The programs are intended for people who want to learn receiving and sending Morse code. unixcw is developed and tested primarily on GNU/Linux system. For general description of changes see HISTORY file. For detailed description of changes see NEWS file. For details on building unixcw from sources see INSTALL file. For acknowledgements see THANKS file. For full text of software license see COPYING file. The heart of the unixcw package is libcw library. It offers the following basic CW services to a caller program: - Morse code character translation tables, and lookup functions - Morse code low-level timing calculations - A 'sidetone' generation and queueing system, using either the system sound card or the console speaker - Optional keying control for an external device, say a transmitter, or an oscillator - CW character and string send routines, tied in with the character lookup - CW receive routines, also tied in to the character lookup - Adaptive speed tracking of received CW - An iambic keyer, with both Curtis 8044 types A and B timing - Straight key emulation The library uses signals and threads to create a background task in which it performs the majority of its work, leaving the main program free to handle other tasks. For example, the simplest CW sending program that uses the library looks like this (compile it with "gcc -lcw example.c"): #include int main () { /* Library initialization */ cw_generator_new(CW_AUDIO_SOUNDCARD, NULL); cw_generator_start(); /* Start the string sending in the background. */ cw_send_string("Hello, world"); /* Wait for the string send to complete. */ cw_wait_for_tone_queue(); /* Library cleanup */ cw_generator_stop(); cw_generator_delete(); return 0; } Instead of the cw_wait_for_tone_queue() call, this program could instead handle any other work it has to do, asynchronously from the CW library's sending. As well as the handful of applications included in unixcw, the following types of programs might also use libcw as their core: - a fully graphical CW send and receive station - a 'CWbiff' that announces incoming email sender in CW - an offline CW reader program, capable of decoding CW from MP3 or other audio file formats - a simple Iambic keyer for an external transmitter, using the mouse buttons as the keyer paddles - a more comprehensive CW tutor program - an automated Morse Code testing application libcw is written in C for easy portability and use. In addition to libcw, the package comes with four basic applications: - cw: a CW sending 'engine' that reads characters from stdin, sounds them on either the sound card or the console speaker, and echoes them to stdout. - cwgen: a simple random character generator that can be used as a feed for cw. For example: cwgen | cw - cwcp: a curses-based program that generates groups of characters from selected sets, words, and CW abbreviations randomly, and sounds them using libcw. It owes much to CP222.EXE, by VU2ZAP. - xcwcp: a CW tutor program for X Window environment. It offers the same random and keyboard sending as 'cwcp', and in addition can read CW that sent to it using the keyboard or mouse as a keyer, making it useful for sending as well as receiving practice.

The core of the package is libcw, a general-purpose CW functions library. There are four programs in the package built around this library: a simple Morse code sounding program; a small random character generator; a curses-based Morse code tutor; and a Qt4-based (X Window) Morse code tutor. The Qt4-based tutor program offers send practice as well as receive. The package includes complete man pages.

It contains routines for converting characters into Morse code representations and back again, for sending Morse code characters, and for receiving characters. It also contains routines to emulate an Iambic Morse keyer, and a straight key. .PP The library can be included in any program that wishes to make use of these features. It forms the heart of three Morse code tutor applications that accompany the package in which it is distributed. .PP See the \fBcw\fP(7) man page for information on Morse code timings, and the dot and dash representations for the various Morse characters. .\" .\" .\" .SS TONE QUEUE .\" .B libcw contains an inbuilt tone queue. The queue is emptied by background processing, using SIGALRM calls and itimers, so a caller program can continue with other tasks while the library sends tones and keys any external device. .PP As well as being used by the library functions that sound Morse code characters and provide a keyer sidetone, the primitive tone queue functions are publicly available to caller programs. .PP .\" .\" .\" .SS CONTROLLING AN EXTERNAL DEVICE .\" .B libcw may be passed the address of a function that controls external keying. This function is called each time the library changes the keying state, either as a result of sending a Morse character or representation, or as a result of an iambic keyer or straight key state change. The argument passed is a single integer, TRUE for key-down, and FALSE for key-up. .PP .B libcw calls the external keying function only when the keying state changes. A call is likely each time a tone is taken off the tone queue. .PP .\" .\" .\" .SS SENDING CW CHARACTERS AND STRINGS .\" .B libcw offers several functions that send individual characters and character strings as Morse code. It also offers functions that allow specialized 'representations' to be sent. A 'representation' is an ASCII string that consists of only the characters '.' and '-'. .PP Characters and strings are converted into representations, and then the correct tones for the dots and dashes in these representations are queued on the tone queue, for action by the background queue emptying process. .PP .\" .\" .\" .SS RECEIVING CW CHARACTERS AND REPRESENTATIONS .\" .B libcw contains functions to allow it to receive Morse code. To receive, the library must be told when a tone start is detected, and when a tone end is detected. It then determines whether the tone was a dot or a dash depending on the timing difference between the two. After the required silence gap has passed, the library may be queried to see what the received representation or character was. .PP Errors in receiving may be detected by means of the flags passed back on receive character functions. .PP .\" .\" .\" .SS IAMBIC KEYER .\" .B libcw offers functions to simulate an Iambic Morse keyer. The caller program needs to tell the library of paddle state changes. Iambic keyer functions are mutually exclusive with character send and straight key functions. .PP .\" .\" .\" .SS STRAIGHT KEY .\" .B libcw offers simple functions to allow effective pass-through of straight key information. The caller program needs to tell the library of key state changes. Straight key functions are mutually exclusive with character send and iambic keyer functions. .PP .\" .\" .\" .SS RETURN CODES .\" Some of the library's function return a return code of type int. The return code has two values, as defined in libcw.h: \fBCW_SUCCESS\fP or \fBCW_FAILURE\fP. The two symbolic constants are guaranteed to be identical to boolean \fBtrue\fP and \fBfalse\fP. .PP .\" .\" .\" .SS FUNCTIONS The following list describes the functions available to a \fBlibcw\fP caller: include(functions) .PP .\" .\" .\" .SH NOTES .\" Despite the fact that this manual page constantly and consistently refers to Morse code elements as dots and dashes, DO NOT think in these terms when trying to learn Morse code. Always think of them as 'dit's and 'dah's. .PP .B libcw uses system itimers for its internal timing. On most UNIX flavours, itimers are not guaranteed to signal a program exactly at the specified time, and they generally offer a resolution only as good as the normal system 'clock tick' resolution. An itimer SIGALRM usually falls on a system clock tick, making it accurate to no better than 10mS on a typical 100Hz kernel. .PP The effect of this is that an itimer period is generally either exactly as specified, or, more likely, slightly longer. At higher WPM settings, the cumulative effect of this affects timing accuracy, because at higher speeds, there are fewer 10mS clock ticks in a dot period. For example, at 12 WPM, the dot length is 100mS, enough to contain five kernel clock ticks; at 60 WPM, the dot length is 20mS, or just two kernel clock ticks. So at higher speeds, the effect of itimer resolutions becomes more pronounced. .PP .\" .\" .\" .SH SEE ALSO .\" Man pages for \fBcw\fP(7,LOCAL), \fBcw\fP(1,LOCAL), \fBcwgen\fP(1,LOCAL), \fBcwcp\fP(1,LOCAL), and \fBxcwcp\fP(1,LOCAL). .\" unixcw-3.5.0/src/libcw/libdoc.awk0000644000175000017500000001551012451007257016512 0ustar acerionacerion#!/bin/awk -f # # Copyright (C) 2001-2006 Simon Baldwin (simon_baldwin@yahoo.com) # Copyright (C) 2011-2015 Kamil Ignacak (acerion@wp.pl) # # This program is free software; you can redistribute it and/or # modify it under the terms of the GNU General Public License # as published by the Free Software Foundation; either version 2 # of the License, or (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Receive a series of marks and spaces. Interpret them as characters. There are two ways of feeding marks and spaces to receiver. First of them is to notify receiver about "begin of mark" and "end of mark" events. Receiver then tries to figure out how long a mark or space is, what type of mark (dot/dash) or space (inter-mark, inter-character, inter-word) it is, and when a full character has been received. This is done with cw_start_receive_tone() and cw_end_receive_tone() functions. The second method is to inform receiver not about start and stop of marks (dots/dashes), but about full marks themselves. This is done with cw_receive_buffer_dot() and cw_receive_buffer_dash() - two functions that are one level of abstraction above functions from first method. Currently there is only one method of passing received data (characters) from receiver to client code. This is done by client code cyclically polling the receiver with cw_receive_representation() or with cw_receive_character() which is built on top of cw_receive_representation(). Duration (length) of marks, spaces and few other things is in microseconds [us], unless specified otherwise. */ #include "config.h" #include #include #include #include #include /* sqrt(), cosf() */ #if (defined(__unix__) || defined(unix)) && !defined(USG) # include #endif #if defined(HAVE_STRING_H) # include #endif #if defined(HAVE_STRINGS_H) # include #endif #include "libcw.h" #include "libcw_rec.h" #include "libcw_data.h" #include "libcw_utils.h" #include "libcw_debug.h" #include "libcw_test.h" extern cw_debug_t cw_debug_object; extern cw_debug_t cw_debug_object_ev; extern cw_debug_t cw_debug_object_dev; /* See also enum of int values, declared in libcw_rec.h. */ static const char *cw_receiver_states[] = { "RS_IDLE", "RS_MARK", "RS_SPACE", "RS_EOC_GAP", "RS_EOW_GAP", "RS_EOC_GAP_ERR", "RS_EOW_GAP_ERR" }; /* Receive and identify a mark. */ static int cw_rec_identify_mark_internal(cw_rec_t *rec, int mark_len, char *representation); /* Functions handling receiver statistics. */ static void cw_rec_update_stats_internal(cw_rec_t *rec, stat_type_t type, int len); static double cw_rec_get_stats_internal(cw_rec_t *rec, stat_type_t type); /* Functions handling averaging data structure in adaptive receiving mode. */ static void cw_rec_update_average_internal(cw_rec_averaging_t *avg, int mark_len); static void cw_rec_update_averages_internal(cw_rec_t *rec, int mark_len, char mark); static void cw_rec_reset_average_internal(cw_rec_averaging_t *avg, int initial); static void cw_rec_poll_representation_eoc_internal(cw_rec_t *rec, int space_len, char *representation, bool *is_end_of_word, bool *is_error); static void cw_rec_poll_representation_eow_internal(cw_rec_t *rec, char *representation, bool *is_end_of_word, bool *is_error); /** \brief Allocate and initialize new receiver variable Before returning, the function calls cw_rec_sync_parameters_internal() for the receiver.

See comment from this article, starting with "This is my soundcard initialization function": http://stackoverflow.com/questions/3345083/correctly-sizing-alsa-buffers-weird-api Poster sets basic audio playback parameters (channels, sampling rate, sample format), saves the config (with snd_pcm_hw_params()), and then only queries ALSA handle for period size and period time. It turns out that it works in our case: basic hw configuration plus getting period size (I don't need period time). Period size seems to be the most important, and most useful data that I need from configured ALSA handle - this is the size of audio buffer which I can fill with my data and send it down to ALSA internals (possibly without worrying about underruns; if I understand correctly - if I send to ALSA chunks of data of proper size then I don't have to worry about underruns). */ #if CW_ALSA_HW_BUFFER_CONFIG && defined(HAVE_SND_PCM_HW_PARAMS_TEST_BUFFER_SIZE) && defined(HAVE_SND_PCM_HW_PARAMS_TEST_PERIODS) /* http://equalarea.com/paul/alsa-audio.html: Buffer size: This determines how large the hardware buffer is. It can be specified in units of time or frames. Interrupt interval: This determines how many interrupts the interface will generate per complete traversal of its hardware buffer. It can be set either by specifying a number of periods, or the size of a period. Since this determines the number of frames of space/data that have to accumulate before the interface will interrupt the computer. It is central in controlling latency. http://www.alsa-project.org/main/index.php/FramesPeriods " "frame" represents the unit, 1 frame = # channels x sample_bytes. In case of stereo, 2 bytes per sample, 1 frame corresponds to 2 channels x 2 bytes = 4 bytes. "periods" is the number of periods in a ring-buffer. In OSS, called "fragments". So, - buffer_size = period_size * periods - period_bytes = period_size * bytes_per_frame - bytes_per_frame = channels * bytes_per_sample The "period" defines the frequency to update the status, usually via the invocation of interrupts. The "period_size" defines the frame sizes corresponding to the "period time". This term corresponds to the "fragment size" on OSS.

Functions operating on one of core elements of libcw: a generator. Generator is an object that has access to audio sink (soundcard, console buzzer, null audio device) and that can play dots and dashes using the audio sink. You can request generator to produce audio by using *_play_*() functions. The inner workings of the generator seem to be quite simple: 1. dequeue tone from tone queue 2. recalculate tone length in usecs into length in samples 3. for every sample in tone, calculate sine wave sample and put it in generator's constant size buffer 4. if buffer is full of sine wave samples, push it to audio sink 5. since buffer is shorter than (almost) any tone, you will push the buffer multiple times per tone 6. if you iterated over all samples in tone, but you still didn't fill up that last buffer, dequeue next tone from queue, go to #2 7. if there are no more tones in queue, pad the buffer with silence, and push the buffer to audio sink. Looks simple, right? But it's the little details that ruin it all.

Make it in two tones, and here is why. Let's say that 'tone queue low watermark' is one element (i.e. one tone). In order for tone queue to recognize that a 'low tone queue' callback needs to be called, the level in tq needs to drop from 2 to 1. Almost every queued character guarantees that there will be at least two tones, e.g for 'E' it is dash + following space. But what about a ' ' character? If we play ' ' character as single tone, there is only one tone in tone queue, and the tone queue manager can't recognize when the level drops from 2 to 1 (and thus the 'low level' callback won't be called). If we play ' ' character as two separate tones (as we do this in this function), the tone queue manager can recognize level dropping from 2 to 1. Then the passing of critical level can be noticed, and "low level" callback can be called. BUT: Sometimes the first tone is dequeued before/during the second one is enqueued, and we can't recognize 2->1 event. So, to be super-sure that there is a recognizable event of passing tone queue level from 2 to 1, we split the eow space into N parts and enqueue them. This way we have N + 1 tones per space, and client applications that rely on low level threshold == 1 can correctly work when enqueueing spaces.

A basic knowledge or understanding of Morse code is a requirement for Radio Amateurs and Marine Radio Operators in many parts of the world. .PP .\" .\" .\" .SS MORSE CODE TIMINGS .\" In Morse code, a dot or dash is referred to as an element. The basic timing unit is the dot period. This is the time taken to send a dot, not including any space before or after the dot. The lengths of all other elements are then derived from this basic unit, using the following rules: .IP The duration of a dash is three dots. .IP The time between each element (dot or dash) is one dot length. .IP The space between characters is three dot lengths. .IP The space between words is seven dot lengths. .PP The following formula calculates the dot period in microseconds from the Morse code speed in words per minute: .IP .nf dot period = ( 1200000 / speed ) .fi .PP This formula arises from the use of the word PARIS as a 'standard' word for calibrating Morse code speed. PARIS is 50 units long when sent in Morse code. Analysis of English plain-text indicates that the average word is 50 units, including spaces. .PP .\" .\" .\" .SS MORSE CODE CHARACTERS .\" The following list shows the IS0 8859-1 (Latin-1) characters that have commonly understood representations in Morse code: .IP .\" \[u0022] = ", otherwise emacs syntax highlighting is messed up; ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789\[u0022]$()+\-./:;=?_@ and space .PP In addition, following ISO 8859-1 and ISO 8859-2 accented characters are also part of the generally accepted international Morse code: .IP .\" ÜÄÇÖÉČŔŃŞŽ \[:U]\[:A]\[,C]\[:O]\['E]\[`E]\[`A]\[~N]\[S u0327] (S with cedilla), \[Z u030C] (Z with caron/hacek), .PP Finally, \fBlibcw\fP adds the following ASCII characters as extensions to single character procedural signals: .IP <>!&^~ .PP .\" .\" .\" .SS MORSE CODE CHARACTER TABLES .\" The following table shows the Morse code equivalents for the ISO 8859-1, accented ISO 8859-1, and accented ISO 8859-2 characters above.

Tone queue - a circular list of tone durations and frequencies pending, and a pair of indexes, tail (enqueue) and head (dequeue) to manage additions and asynchronous sending. The tone queue (the circular list) is implemented using constant size table. Explanation of "forever" tone: If a "forever" flag is set in a tone that is a last one on a tone queue, the tone should be constantly returned by dequeue function, without removing the tone - as long as it is a last tone on queue. Adding new, "non-forever" tone to the queue results in permanent dequeuing "forever" tone and proceeding to newly added tone. Adding new, "non-forever" tone ends generation of "forever" tone. The "forever" tone is useful for generating tones of length unknown in advance. dequeue() function recognizes the "forever" tone and acts as described above; there is no visible difference between dequeuing N separate "non-forever" tones of length L [us], and dequeuing a "forever" tone of length L [us] N times in a row. Because of some corner cases related to "forever" tones it is very strongly advised to set "low water mark" level to no less than 2 tones. */ #include /* "PRIu32" */ #include #include #include #include /* SIGALRM */ #include "libcw.h" #include "libcw_tq.h" #include "libcw_gen.h" #include "libcw_debug.h" #include "libcw_signal.h" #if defined(HAVE_STRING_H) # include #endif #if defined(HAVE_STRINGS_H) # include #endif /* The CW tone queue functions implement the following state graph: (queue empty) +-----------------------------------------------------+ | | | | | (tone(s) added to queue, | v dequeueing process started) | ----> CW_TQ_IDLE -------------------------------> CW_TQ_BUSY --+ ^ | | | +--------+ (queue not empty) Above diagram shows two states of a queue, but dequeue function returns three distinct values: CW_TQ_DEQUEUED, CW_TQ_NDEQUEUED_EMPTY, CW_TQ_NDEQUEUED_IDLE.

The queue returns three distinct values. This may seem overly complicated for a tone queue, but it actually works. The way the generator interacts with the tone queue, and the way the enqueueing works, depend on the dequeue function to return three values. If you ever try to make the dequeue function return two values, you would also have to redesign parts of generator and of enqueueing code. Look in cw_gen_write_to_soundcard_internal(). The function makes decision based on two distinct tone queue states (described by CW_TQ_DEQUEUED or CW_TQ_NDEQUEUED_EMPTY). So the _write() function must be executed by generator for both return values. But we also need a third return value that will tell the generator not to execute _write() *at all*, but just wait for signal. This third value is CW_TQ_NDEQUEUED_IDLE. These three return values are: \li CW_TQ_DEQUEUED - dequeue() function successfully dequeues and returns through \p tone a valid tone. dequeue() understands how "forever" tone should be handled: if such tone is the last tone on the queue, the function actually both returns the "forever" tone, and keeps it in queue (until next tone is enqueued). \li CW_TQ_NDEQUEUED_EMPTY - dequeue() function can't dequeue a tone from tone queue, because the queue has been just emptied, i.e. previous call to dequeue() was successful and returned CW_TQ_DEQUEUED, but that was the last tone on queue. This return value is a way of telling client code "I've had tones, but no more, you should probably stop playing any sounds and become silent". If no new tones are enqueued, the next call to dequeue() will return CW_TQ_NDEQUEUED_IDLE. \li CW_TQ_NDEQUEUED_IDLE - dequeue() function can't dequeue a tone from tone queue, because the queue is empty, and the tone queue has no memory of being non-empty before. This is the value that dequeue() would return for brand new tone queue. This is also value returned by dequeue() when its previous return value was CW_TQ_NDEQUEUED_EMPTY, and no new tones were enqueued since then. Notice that returned value does not describe internal state of tone queue. Successfully dequeued tone is returned through function's argument \p tone. The function does not modify the arguments if there are no tones to dequeue (CW_TQ_NDEQUEUED_EMPTY, CW_TQ_NDEQUEUED_IDLE). As mentioned above, dequeue() understands how "forever" tone works. If the last tone in queue has "forever" flag set, the function won't permanently dequeue it. Instead, it will keep returning (through \p tone) the tone on every call, until a new tone is added to the queue after the "forever" tone. testedin::test_cw_tq_dequeue_internal() testedin::test_cw_tq_test_capacity_2() \param tq - tone queue \param tone - dequeued tone \return CW_TQ_DEQUEUED (see information above) \return CW_TQ_NDEQUEUED_EMPTY (see information above) \return CW_TQ_NDEQUEUED_IDLE (see information above) */ int cw_tq_dequeue_internal(cw_tone_queue_t *tq, /* out */ cw_tone_t *tone) { pthread_mutex_lock(&(tq->mutex)); /* Decide what to do based on the current state. */ switch (tq->state) { case CW_TQ_IDLE: pthread_mutex_unlock(&(tq->mutex)); /* Ignore calls if our state is idle. */ return CW_TQ_NDEQUEUED_IDLE; case CW_TQ_BUSY: /* If there are some tones in queue, dequeue the next tone.

Every dictionary has a description (dictionary's label), and a list of words that are the body of a dictionary. "words" is used loosely: the words can be real, multi-character words, or just single letters. Every dictionary has a 'group size' property, telling if words in a dictionary are only single-character words, or multi-character words. Dictionaries can be stored in a text file between two sessions of a program. Dictionaries stored in a memory are put on a linked list. There can be only one such list at a time. Description of a given dictionary is in first line in square brackets, and in following line is a list of words. Words are separated by space characters. Examples (yes, this looks like contents of .ini file): [ Digits ] 1 2 3 4 5 6 7 8 9 0 [ A-K ] A B C D E F G H I J K [ My favourite nouns ] coffee C vacation Linux Comments in file are allowed (and skipped): lines starting with ';' or '#' characters are considered to be comments. Usually an application uses several dictionaries, and a file can also store few dictionaries. The module has its own, internal, default list of cw dictionaries.

If defined, these options are used first; command line options take precedence. .PP .\" .\" .\" .SH DESCRIPTION .\" .PP .B cwgen provides a simple method to generate groups of random characters for use as input into \fBcw\fP. Command line options control the group size, number of groups, and character set from which the random characters are selected. .PP .\" .\" .\" .SS COMMAND LINE OPTIONS .\" .B cwgen understands the following command line options. The long form options may not be available in non-LINUX versions. .TP .I "\-g, \-\-groups" Specifies the number of groups of random characters to generate. The default value is 128. .TP .I "\-n, \-\-groupsize" Specifies either the number of random characters in each group, if a single value is given, or a range for the number of random characters in each group if a dash-separated pair of values is given. If a range is given, \fBcwgen\fP generates groups sized randomly between 'group_min' and 'group_max'. The default value is 5. .TP .I "\-r, \-\-repeat" Specifies the number of times to repeat each group. The default value is 0, indicating that each group is printed just once. .TP .I "\-x, \-\-limit" Specifies an upper limit on the number of characters printed. This option is useful when using random group sizes, to ensure a given amount of practice text. The default value is 0, indicating no upper limit on the number of characters printed. .TP .I "\-c, \-\-charset" Defines the character set from which the random characters are selected. The default value is 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'. .PP .\" .\" .\" .SH EXAMPLES .\" Generate 20 groups of 10 characters from the set EISH5, and sound them as Morse code. Both short-form and long-form option examples are shown: .IP cwgen \-g 20 \-n 10 \-c "EISH5" | cw \-w 25 \-t 850 .IP cwgen \-\-groups=20 \-\-groupsize=10 \-\-charset="EISH5" | cw \-\-wpm=25 \-\-tone=850 .PP .\" .\" .\" .SH SEE ALSO .\" Man pages for \fBcw\fP(7,LOCAL), \fBlibcw\fP(3,LOCAL), \fBcw\fP(1,LOCAL), \fBcwcp\fP(1,LOCAL), and \fBxcwcp\fP(1,LOCAL). .\" unixcw-3.5.0/src/cwgen/cwgen.c0000644000175000017500000002702012575332612016026 0ustar acerionacerion/* * Copyright (C) 2001-2006 Simon Baldwin (simon_baldwin@yahoo.com) * Copyright (C) 2011-2015 Kamil Ignacak (acerion@wp.pl) * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * as published by the Free Software Foundation; either version 2 * of the License, or (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

If defined, these options are used first; command line options take precedence. .PP .\" .\" .\" .SH DESCRIPTION .\" .PP .B xcwcp is a X Window-based interactive Morse code tutor program. It lets you choose from a number of options for practice, including sending random characters, random words, and characters from the keyboard. It will also receive Morse code that you send using the keyboard or mouse as a Morse keyer, and display the characters it sees. .PP .\" .\" .\" .SS COMMAND LINE OPTIONS .\" .B xcwcp understands the following command line options. The long form options may not be available in non-LINUX versions. .TP .I "\-s, \-\-system=SYSTEM" Specifies the way that \fBxcwcp\fP generates tones. Valid values are: \fIconsole\fP for tones through the console speaker, \fIalsa\fP for tones generated through the system sound card using ALSA sound system, \fIoss\fP for tones generated through system sound card using OSS sound system, \fIsoundcard\fP for tones generated through the system sound card, but without explicit selection of sound system. These values can be shortened to 'c', 'a', 'o', or 's', respectively. The default value is 'oss'. .TP .I "\-d, \-\-device=DEVICE" Specifies the device file to open for generating a sound. \fBxcwcp\fP will use default device if none is specified. The default devices are: \fI/dev/console\fP for sound produced through console, \fIdefault\fP for ALSA sound system, \fI/dev/audio\fP for OSS sound system. See also \fINOTES ON USING A SOUND CARD\fP below. .TP .I "\-w, \-\-wpm=WPM" Sets the initial sending speed in words per minute. The value must be between 4 and 60. The default value is 12 WPM. .TP .I "\-t, \-\-tone=HZ" Sets the initial sounder pitch in Hz. This value must be between 0 and 4,000. A value of 0 selects silent operation, and can be used for timing checks or other testing. The default value is 800Hz, .TP .I "\-v, \-\-volume=PERCENT" Sets the initial sending volume, as a percentage of full scale volume. The value must be between 0 and 100. The default value is 70 %. Sound volumes work fully for sound card tones, but \fBxcwcp\fP cannot control the volume of tones from the console speaker. In this case, a volume of zero is silent, and all other volume values are simply sounded. .TP .I "\-g, \-\-gap=GAP" Sets the initial extra gap, in dot lengths, between characters (the 'Farnsworth' delay). It must be between 0 and 60. The default is 0. .TP .I "\-f, \-\-infile=FILE" Specifies a text file that \fBxcwcp\fP can read to configure its practice text. See \fICREATING CONFIGURATION FILES\fP below. .TP .I "\-F, \-\-outfile=FILE" Specifies a text file to which \fBxcwcp\fP should write its current practice text. .PP .\" .\" .\" .SS USER INTERFACE .\" .B xcwcp offers GUI controls for changing the speed, tone frequency, 'Farnsworth' gap, and mode of the program. All of the major controls are placed on the application toolbar. .PP The main GUI window is used to display the characters that \fBxcwcp\fP sends or receives. .PP To find out more about what a particular GUI control does, use the "What's this..." icon (the '?' at the far right of the toolbar). .PP .\" .\" .\" .SS RANDOM CHARACTERS AND WORDS .\" .B xcwcp sends random characters in groups of five, with a space between each group. .PP When sending random words, \fBxcwcp\fP sends the complete word, followed by a space. Because short words are easier to copy without writing, \fBxcwcp\fP's default dictionary contains only three, four, and five-letter words in its random words list. .PP .B xcwcp chooses at random from a list of around 3000 words in its default dictionary. You can change this text using a configuration file, read at startup. See \fICREATING CONFIGURATION FILES\fP below. .PP .\" .\" .\" .SS RECEIVING MORSE .\" .B xcwcp can receive Morse code, and display it in its main GUI window. To key Morse code into the program, select the Receive Keyed CW mode, and press the stop/start button. Now, place the mouse cursor over the central window of the program. By pressing the middle mouse button, you should be able to key Morse into the program as if the mouse button was a straight Morse key. .PP For better keying, you can use the left and right mouse buttons as if they were paddles on an Iambic keyer. This will send Morse code at the exact rate set on the Speed control. .PP You can also use the keyboard for keying. In this case, any of the Up or Down cursor keys, Space, Enter, or Return may be used as the straight key, and the Left and Right cursor keys act as the two paddles of an Iambic keyer. .PP By default, \fBxcwcp\fP will try to follow the speed of the Morse code that you send to it. It is possible to switch this tracking off, in which case the program switches to receiving only at the exact speed set on the Speed control. However, fixed speed receiving is very, very picky about receiving only extremely accurately timed Morse code, so unless you are striving for complete perfection, you may find that speed tracking is more comfortable. .PP The speed tracking in \fBxcwcp\fP can sometime be confused by very wide and abrupt changes in speed. If it is having difficulty finding the speed you are sending at, you can use the File pulldown menu to synchronize the receive speed to the speed set on the Speed control. .PP At any time, the mode selection combowidget can get focus by using Alt+M. You can then use the space bar or the up/down keys to change the mode. The Tab key moves to the next widget, so you can change speed, etc. Shift+Tab moves backwards. .PP .\" .\" .\" .SS NOTES ON USING A SOUND CARD .\" By default, \fBxcwcp\fP tries to open OSS device "/dev/audio" to access the system sound card. This is generally the correct device to use, but for systems with special requirements, or those with multiple sound cards, the option \fI-d\fP or \fI\-\-device\fP, combined with \fI-s\fP or \fI\-\-system\fP can be used to specify the device and audio system for sound card access. If the sound card device cannot be set up, \fBxcwcp\fP prints the error message .IP cannot set up soundcard sound .PP and exits. .PP Sound card devices, when opened through OSS sound system, are usually single-access devices, so that when one process has opened the device, other processes are prevented from using it. In such cases \fBxcwcp\fP will of course conflict with any other programs that expect exclusive use of the system sound card (for example, MP3 players). If \fBxcwcp\fP finds that the sound card is already busy, it prints the error message .IP open /dev/audio: Device or resource busy .PP and exits. .PP .\" The main sound card device will often allow \fBxcwcp\fP to control tone .\" volumes directly, but where this is not possible, \fBxcwcp\fP uses the .\" mixer device instead. By default, this is "/dev/mixer", but the device .\" can be specified with the \fI-y\fP or \fI\-\-mdevice\fP options. In .\" general, as with the main sound card device, the default mixer device .\" is usually the correct one to use. .\" .PP .\" The mixer device is only used if the sound card does not allow volume .\" control through the main sound card device. .PP The sound card device is not used if \fBxcwcp\fP is only sending tones on the console speaker. .PP .\" .\" .\" .SS AUDIO OUTPUT \- DEFAULTS AND SELECTION .\" \fBxcwcp\fP first tries to access sound card using PulseAudio sound system, using default device name, unless user specifies other audio device with option \fI-d\fP or \fI\-\-device\fP. .PP \fBxcwcp\fP then tries to access sound card using OSS audio system and default OSS audio device name ('/dev/audio'), unless user specifies other audio device with option \fI-d\fP or \fI\-\-device\fP. .PP If opening soundcard through OSS fails, \fBxcwcp\fP tries to access the sound card using ALSA audio system, and default ALSA audio device name ('default'), unless user specifies other audio device with option \fI-d\fP or \fI\-\-device\fP. .PP If opening soundcard through ALSA also fails, \fBxcwcp\fP tries to access system console buzzer using default buzzer device '/dev/console', unless user specifies other audio device with option \fI-d\fP or \fI\-\-device\fP. .PP It is very common that in order to access the console buzzer device user has to have root privileges. For that reason trying to open console buzzer almost always fails. This is not a program's bug, this is a result of operating system's restrictions. Making \fBxcwcp\fP an suid binary bypasses this restriction. The program does not fork() or exec(), so making it suid should be relatively safe. Note however that this practice is discouraged for security reasons. .PP As stated, user can tell \fBxcwcp\fP which device to use, using \fI-d\fP or \fI\-\-device\fP option. Which device files are suitable will depend on which operating system is running, which system user ID runs \fBxcwcp\fP, and which user groups user belongs to. .PP .\" .\" .\" .SS CREATING CONFIGURATION FILES .\" .B xcwcp contains a default set of modes and practice text that should be enough to begin with. It can however read in a file at startup that reconfigures these to provide different character groupings, word sets, and other practice data. .PP To read a configuration file, use the \fI-i\fP or \fI\-\-infile\fP command line option. The file should introduce each \fBxcwcp\fP mode with a section header in '[' ... ']' characters, followed by the practice text for that mode, with elements separated by whitespace. Lines starting with a semicolon or hash are treated as comments. For example .IP ; Simple example mode .br [ A to Z ] .br A B C D E F G H I J K L M N O P Q R S T U V W X Y Z .PP .B xcwcp will generate five character groups for modes whose elements are all single characters, and treat other modes as having elements that are complete words. As a starting point for customized modes, \fBxcwcp\fP will write its default configuration to a file if given the undocumented \fI-#\fP option, for example "xcwcp -# /tmp/xcwcp.ini". .\" .\" .\" .SH NOTES .\" .B xcwcp is an X Window rewrite of \fBcwcp\fP. Both programs borrow heavily from the the DOS Morse code tutor CP222C.EXE, by VU2ZAP. .PP The characters echoed in the main GUI window may be ASCII equivalents of Morse procedural signals; see the \fBcw\fP(7,LOCAL) man page for details. .\" .\" .\" .SS HINTS ON LEARNING MORSE CODE .\" Here are a few hints and tips that may help with the process of learning Morse code. .PP Firstly, do \fBNOT\fP think of the elements as dots and dashes. Instead, think of them as dits and dahs (so 'A' is di-dah). If you think of them in this way, the process of translating sound into characters will be learned much more easily. .PP Do not learn the characters from a table. Learn them by watching the groups appear on the screen, and listening to the sounds produced as each is sent. In the very initial stages, it may be beneficial if you can find a person to take you through the first stages of recognising characters. .PP Do not waste your time learning Morse code at 5 WPM. Set the speed to 12 or 15 WPM, but use extra spacing (the Gap window) to reduce the effective speed to much lower - around four or five WPM \fIeffective\fP speed. This way, you will learn the rhythm of the characters as they are sent, but still have plenty of time between characters. As you practice, decrease the gap to zero. .PP Learn in stages. Start by learning the \fIEISH5\fP group, then progress down through the menu as each group is mastered. The groups contain characters which are in some way related, either by sound, or by type of character. .PP Once you have completed all the groups \fIEISH5\fP to \fI,?.;)/\fP (or \fI23789\fP if you do not want to learn procedural signals yet), use the full character set options, and the words and CW words options, to sharpen your skill. If you have difficulties with particular characters, return to that group and practice again with a smaller character set. .PP Resist the temptation to try to learn or improve your speed by copying off-air. You will not know what speed you are working at, and much hand-sent Morse is not perfectly formed. What you can gain off-air though is a general 'resilience', a tolerance for Morse code where the timing of individual elements, or spacing between characters and words, is not 100% accurate. .PP If working to attain a particular speed for a test, always set the speed slightly higher. For example, if aiming for 12 WPM, set the tutor speed to 14 or 15 WPM. This way, when you drop back to 12 WPM you will feel much more relaxed about copying. Be aware that \fBxcwcp\fP is not necessarily going to send at exactly the speed you set, due to limitations in what can be done with UNIX timers. It often sends at a slower speed than you set, so be very careful with this if you have a target speed that you need to reach. .PP Use the program to make cassette tapes that you can take with you in a walkman or in the car, for long journeys. You do not have to write down everything you hear to practice Morse code. Simply listening to the shapes of characters over a period will help to train your brain into effortless recognition. In fact, slavishly writing everything down becomes a barrier at speeds of 15-20 WPM and above, so if you can begin to copy without writing each character down, you will find progress much easier above these speeds. But do not over-use these tapes, otherwise you will quickly memorise them. Re-record them with new contents at very regular intervals. .PP Try to spend at least 15-30 minutes each day practicing. Much less than this will make progress glacially slow. But significantly more than an hour or so may just result in you becoming tired, but not improving. Recognise when it is time to stop for the day. .PP Do not worry if you reach a speed 'plateau'. This is common, and you will soon pass it with a little perseverance. .PP At higher speeds, CW operators tend to recognise the 'shape' of whole words, rather than the individual characters within the words. The CW words menu option can be used to help to practice and develop this skill. .PP Neither the mouse buttons nor the keyboard are ideal for use a keys or keyer paddles, for sending practice. Try to use a proper key for sending where possible. It is hard even for experienced operators to get good keying using the mouse or keyboard. Of the two, the mouse is probably the better option, though, in a pinch. .PP .\" .\" .\" .SH ERRORS AND OMISSIONS .\" The calibration option is a bit ropy. It simply sends PARIS repeatedly, and relies on you to time the sending and then work out if any adjustment to the speed is really necessary.

If defined, these options are used first; command line options take precedence. .PP .\" .\" .\" .SH DESCRIPTION .\" .PP \fBcw\fP reads characters from an input file, or from standard input, and sounds each valid character as Morse code on either the system sound card, or the system console speaker. After it sounds a character, \fBcw\fP echoes it to standard output. The input stream can contain embedded command strings. These change the parameters used when sounding the Morse code. \fBcw\fP reports any errors in embedded commands on standard error. .PP Use 'Ctrl+D' key combination to exit \fBcw\fP. .\" .\" .\" .SS COMMAND LINE OPTIONS .\" \fBcw\fP understands the following command line options. The long form options may not be available in non-LINUX versions. .TP .I "\-s, \-\-system=SYSTEM" Specifies the way that \fBcw\fP generates tones. Valid values are: \fInull\fP for no tones, just timings, \fIconsole\fP for tones through the console speaker, \fIalsa\fP for tones generated through the system sound card using ALSA sound system, \fIoss\fP for tones generated through system sound card using OSS sound system, \fIpulseaudio\fP for tones generated through system sound card using PulseAudio sound system, \fIsoundcard\fP for tones generated through the system sound card, but without explicit selection of sound system. These values can be shortened to 'n', 'c', 'a', 'o', 'p', or 's', respectively. The default value is 'pulseaudio' (on systems with PulseAudio installed), followed by 'oss'. .TP .I "\-d, \-\-device=DEVICE" Specifies the device file to open for generating a sound. \fBcw\fP will use default device if none is specified. The default devices are: \fI/dev/console\fP for sound produced through console, \fIdefault\fP for ALSA sound system, \fI/dev/audio\fP for OSS sound system, \fIa default device\fP for PulseAudio sound system. See also \fINOTES ON USING A SOUND CARD\fP below. .TP .I "\-w, \-\-wpm=WPM" Sets the initial sending speed in words per minute. The value must be between 4 and 60. The default value is 12 WPM. .TP .I "\-t, \-\-tone=HZ" Sets the initial sounder pitch in Hz. This value must be between 0 and 4,000. A value of 0 selects silent operation, and can be used for timing checks or other testing. The default value is 800Hz, .TP .I "\-v, \-\-volume=PERCENT" Sets the initial sending volume, as a percentage of full scale volume. The value must be between 0 and 100. The default value is 70 %. Sound volumes work fully for sound card tones, but \fBcw\fP cannot control the volume of tones from the console speaker. In this case, a volume of zero is silent, and all other volume values are simply sounded. .TP .I "\-g, \-\-gap=GAP" Sets the initial extra gap, in dot lengths, between characters (the 'Farnsworth' delay). It must be between 0 and 60. The default is 0. .TP .I "\-k, \-\-weighting=WEIGHT" Sets the initial weighting, as a percentage of dot lengths. It must be between 20 and 80. The default is 50. .TP .I "\-e, \-\-noecho" Stops \fBcw\fP echoing characters on standard output after they are sounded. The default is to have echoing on. .TP .I "\-m, \-\-nomessages" Stops \fBcw\fP printing error messages on standard error. The default is to print messages. .TP .I "\-c, \-\-nocommands" Stops \fBcw\fP from interpreting commands embedded in the input stream. The default is to interpret embedded commands. .TP .I "\-o, \-\-nocombinations" Stops \fBcw\fP from treating character strings bracketed by [...] as a single combination character. The default is to honor combinations. .TP .I "\-p, \-\-nocomments" Stops \fBcw\fP from treating character strings bracketed by {...} as 'comments'. Characters inside these braces will be echoed to standard output, but not sounded. When comments are being honored, any embedded commands inside the braces will be ignored. The default is to honor comments. .TP .I "\-f, \-\-infile=FILE" Specifies a text file that \fBcw\fP can read to configure its practice text. .TP .I "\-h, \-\-help" Prints short help message. .TP .I "\-V, \-\-version" Prints information about program's version, authors and license. .PP .\" .\" .\" .SS SOUNDING CHARACTERS .\" \fBcw\fP reads characters, one at a time, from its standard input or from its input file. Lowercase letters are converted internally to uppercase. The following list shows the valid IS0 8859-1 (Latin-1) characters that can be sounded by \fBcw\fP: .\" \[u0022] = ", otherwise emacs syntax highlighting is messed up; .IP ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789\[u0022]$()+\-./:;=?_@ and space .PP In addition, the program also understands the following ISO 8859-1 and ISO 8859-2 accented characters: .\" .\" .\" �������Ѫ� .\" .\" .\" This looks like a great place for tutorial on non-standard characters .\" in troff document tutorial ;) .\" .\" Q: how to produce '�' ('S' with Cedilla)? .\" A: use composite glyph; 'man 7 groff_char' gives this syntax of .\" composite glyph: .\" \[base_glyph composite_1 composite_2 ...] .\" For '�' base glyph is 'S', and first (and only) composite is .\" 'cedilla', represented by Unicode thingy 'u0327'. Thus: .\" '�' = '\[S u0327]'; .\" .\" Q: how to produce '�' ('Z' with caron/hacek)? .\" A: in two ways: either as a composite glyph as demonstrated above), .\" i.e. like this: '\[Z u030C]', or in 'regular' way, using .\" non-composite glyph \[vZ]' .\" .\" Q: any more tips? .\" A: two: .\" - read 'man 7 groff_char' (or 'man 7 troff_char'); .\" - make sure that your terminal (terminal emulator) can display .\" non-standard characters correctly (and I mean *really* correctly); .\" make a little test: open 'man 7 troff_char' in your terminal, .\" and open web page with html version of the man page, then search .\" for non-standard characters (e.g. cedilla) in the html document .\" and compare them with those displayed in the terminal; .\" .\" .\" .\" .IP \[:U]\[:A]\[,C]\[:O]\['E]\[`E]\[`A]\[~N]\[S u0327] (S with cedilla), \[vZ] (Z with caron/hacek), .PP and accepts the following as single character forms of common procedural signals: .IP <>!&^~ .PP See \fBcw\fP(7,LOCAL) for more information on the above characters and Morse code. .PP If \fBcw\fP receives a character not in this set, it prints an error message '?\fIc\fP', where \fIc\fP is the error character. The only exceptions to this may be the \fBcw\fP command escape character '%', the combination start and stop characters '[' and ']', and the comment start and stop characters '{' and '}'. See \fIEMBEDDED COMMANDS\fP and \fIMORSE CODE COMBINATIONS\fP below. .PP .\" .\" .\" .SS EMBEDDED COMMANDS .\" \fBcw\fP recognizes special sequences in the input stream as embedded commands. These commands alter the parameters of the \fBcw\fP while it is running, or query current values. All commands are prefixed by the command escape character '%', and those which set a value end with a semicolon. .PP The format of an embedded command to change a parameter value is .IP %\fICvalue\fP; .PP where \fIC\fP is a command letter indicating what action \fBcw\fP is to take, and \fIvalue\fP is the argument or value for the command. .PP Valid command letters are .TP .I "T" Sets the tone pitch used to sound a character. .TP .I "W" Sets the sending speed. .TP .I "G" Sets the 'Farnsworth' gap between characters. .TP .I "K" Sets the weighting. .TP .I "E" Disables or re-enables echoing of sent characters on standard output. .TP .I "M" Disables or re-enables error messages on standard error. .TP .I "S" Disables or re-enables speaker tone generation. .TP .I "C" Disables processing of embedded commands. Note that once disabled, this command cannot re-enable them. .TP .I "O" Disables or re-enables recognition of [...] character combinations. .TP .I "P" Disables or re-enables recognition of {...} comments. When comments are being recognized, any character after an opening '{' and before any closing '}' will be echoed to standard output, but will not be sounded, or have any other effect. .PP For example, the embedded command sequence .IP %W25;%T1200; .PP will set \fBcw\fP to a speed of 25 WPM, and a tone pitch of 1200Hz. .PP The 'T', 'W', 'G', and 'A' commands take values along with the command. The limits on values given for embedded commands are the same as the limits available for command line options, detailed above. .PP The 'E', 'M', 'S', 'C' and 'O' commands are flags, and treat a value of zero as clear, and any other value as set. So, for example, the sequence .IP %M0;%C0; .PP will turn off error messages, and then turn off the processing of embedded commands. .PP If a parameter is set successfully, \fBcw\fP reports the new setting on standard error (except if no error messages is set). If an error is detected in an embedded command, \fBcw\fP reports an error. For the formats of error messages see the \fIMESSAGE FORMATS\fP section below. .PP The current values of parameters within \fBcw\fP may be queried, as well as set. The command format .IP %?\fIC\fP .PP queries the value of the parameter normally set with command \fIC\fP. .B cw reports the current value on standard error, using the same format as when new values are set. .PP The current values of parameters within \fBcw\fP may also be requested as output in Morse code. The command format .IP %>\fIC\fP .PP will generate Morse output reporting the value of the parameter normally set with command \fIC\fP. .PP If embedded commands are disabled, '%' characters are treated as any other (in this case, invalid) input character. .PP Once processing of embedded commands has been switched off, any command to switch this feature back on will not be recognized. That is, after '%C0;', an '%C1;' will not be recognized. .PP There is one additional command, and that is '%Q'. This command closes all open files and terminates \fBcw\fP. Any characters after this command in the input stream will be lost. .PP The file \fIcw.h\fP provides a full set of definitions for the commands, special characters, and status codes of \fBcw\fP. .PP .\" .\" .\" .SS MESSAGE FORMATS .\" Where a parameter value is set correctly with an embedded command, the message format .IP \=\fICvalue\fP .PP is returned. \fIC\fP is the command used, and \fIvalue\fP is the new value. .PP If an invalid value is supplied for a parameter in an embedded command, a message .IP ?\fICvalue\fP .PP is returned. .PP Where an invalid command is encountered, the message format .IP ?%\fIC\fP .PP is used. For an invalid query, the message is .IP ??\fIC\fP .PP and for an invalid request for a parameter in Morse code the message is .IP ?>\fIC\fP .PP A character in the input stream that cannot be sounded produces a message .IP ?\fIC\fP .PP These messages are not intended to be user-friendly, but are designed to be easily and quickly interpreted by another program. Similarly, the format of embedded commands is more computer-friendly than user-friendly. .PP If error messages are disabled, no messages of any type are printed on standard error. .PP .\" .\" .\" .SS MORSE CODE COMBINATIONS .\" The standard set of characters offered by \fBcw\fP may not be sufficient for some purposes. For example, some international characters do not have equivalent ISO 8859-1 and ISO 8859-2 that \fBcw\fP can sound directly. .PP To help in sounding such characters, \fBcw\fP offers the ability to form combination characters by placing individual character components between [...] brackets. \fBCw\fP sounds characters inside a combination without the usual gap between them. In this way, any missing character in the set can be built. .PP For example .IP [VA] .PP is one way to form the VA procedural signal, though .IP [SK] .PP works just as well. The eight-dot error signal can be sounded with .IP [HSE] .PP or the C-cedilla in international Morse code with .IP [CE] .PP There can be as many valid letters, numbers, or figures inside the [...] brackets as required. For example, an alternative way of sending the error signal could be .IP [EEEEEEEE] .PP Finally, three alternative ways of sending 73 might be .IP [TTEEE][EEETT] .br [TDE][EUT] .br [GEE][VT] .PP Embedded commands may be placed inside [...] combinations if required. Combinations do not nest. .PP This feature can be disabled by using the \fI\-O\fP or \fI\-\-nocombinations\fP command line flags, or with the 'O' embedded command. If combinations are disabled, '[' and ']' characters are treated as any other (invalid) input character. .PP .\" .\" .\" .SS NOTES ON USING A SOUND CARD .\" By default, \fBcw\fP tries to open default PulseAudio. If PulseAudio server is not accessible, cw tries to open OSS device "/dev/audio" to access the system sound card. This is generally the correct device to use, but for systems with special requirements, or those with multiple sound cards, the option \fI-d\fP or \fI\-\-device\fP, combined with \fI-s\fP or \fI\-\-system\fP can be used to specify the device and audio system for sound card access. If the sound card device cannot be set up, \fBcw\fP prints the error message .IP cannot set up soundcard sound .PP and exits. .PP Sound card devices, when opened through OSS sound system, are usually single-access devices, so that when one process has opened the device, other processes are prevented from using it. In such cases \fBcw\fP will of course conflict with any other programs that expect exclusive use of the system sound card (for example, MP3 players). If \fBcw\fP finds that the sound card is already busy, it prints the error message .IP open /dev/audio: Device or resource busy .PP and exits. .PP .\" The main sound card device will often allow \fBcw\fP to control tone .\" volumes directly, but where this is not possible, \fBcw\fP uses the .\" mixer device instead. By default, this is "/dev/mixer", but the device .\" can be specified with the \fI-y\fP or \fI\-\-mdevice\fP options. In .\" general, as with the main sound card device, the default mixer device .\" is usually the correct one to use. .\" .PP .\" The mixer device is only used if the sound card does not allow volume .\" control through the main sound card device. .PP The sound card device is not used if \fBcw\fP is only sending tones on the console speaker. .PP .\" .\" .\" .SS AUDIO OUTPUT \- DEFAULTS AND SELECTION .\" \fBcw\fP first tries to access sound card using PulseAudio sound system, using default device name, unless user specifies other audio device with option \fI-d\fP or \fI\-\-device\fP. .PP \fBcw\fP then tries to access sound card using OSS audio system and default OSS audio device name ('/dev/audio'), unless user specifies other audio device with option \fI-d\fP or \fI\-\-device\fP. .PP If opening soundcard through OSS fails, \fBcw\fP tries to access the sound card using ALSA audio system, and default ALSA audio device name ('default'), unless user specifies other audio device with option \fI-d\fP or \fI\-\-device\fP. .PP If opening soundcard through ALSA also fails, \fBcw\fP tries to access system console buzzer using default buzzer device '/dev/console', unless user specifies other audio device with option \fI-d\fP or \fI\-\-device\fP. .PP It is very common that in order to access the console buzzer device user has to have root privileges. For that reason trying to open console buzzer almost always fails. This is not a program's bug, this is a result of operating system's restrictions. Making \fBcw\fP an suid binary bypasses this restriction. The program does not fork() or exec(), so making it suid should be relatively safe. Note however that this practice is discouraged for security reasons. .PP As stated, user can tell \fBcw\fP which device to use, using \fI-d\fP or \fI\-\-device\fP option. Which device files are suitable will depend on which operating system is running, which system user ID runs \fBcw\fP, and which user groups user belongs to. .PP .\" .\" .\" .SH NOTES .\" Despite the fact that this manual page constantly and consistently refers to Morse code elements as dots and dashes, DO NOT think in these terms when trying to learn Morse code. Always think of them as 'dit's and 'dah's. .PP The Morse code table in the \fBcw\fP(7,LOCAL) man page is provided for reference only. If learning for the first time, you will be much better off learning by hearing the characters sent, rather than by looking at the table. .PP Other programs running in the system may interfere with the timing of the Morse code that \fBcw\fP is sending. If this is a problem, either try to run on a quiescent system, or try running \fBcw\fP with nice(1L,C,1). UNIX is not really designed for user-level programs to do the sort of fine timing required to send Morse code. \fBcw\fP is therefore more sensitive than most programs to other system activity. .PP .B cw uses system itimers for its internal timing. On most UNIX flavors, itimers are not guaranteed to signal a program exactly at the specified time, and they generally offer a resolution only as good as the normal system 'clock tick' resolution. An itimer SIGALRM usually falls on a system clock tick, making it accurate to no better than 10mS on a typical 100Hz kernel. .PP The effect of this is that an itimer period is generally either exactly as specified, or, more likely, slightly longer. At higher WPM settings, the cumulative effect of this affects timing accuracy, because at higher speeds, there are fewer 10mS clock ticks in a dot period. For example, at 12 WPM, the dot length is 100mS, enough to contain five kernel clock ticks. But at 60 WPM, the dot length is 20mS, or just two kernel clock ticks. So at higher speeds, the effect of itimer resolutions becomes more pronounced. .PP To test itimer timing, first try .IP X="PARIS PARIS PARIS PARIS " .IP echo "$X" | time cw \-w 4 .PP and note the elapsed time, which should be very close to one minute. Next, try .IP echo "$X$X$X$X$X$X$X$X$X$X$X$X" | time cw \-w 48 .PP The elapsed time should be the same. If it has increased, this is the effect of system itimers delaying for slightly longer than the specified period (higher WPM rates make more itimer calls). That's itimers for you, not perfect for this job, but the best there is without writing some, and perhaps a lot of, kernel code. .PP Except for zero, which is silent, tone values lower than 10Hz may not sound at the expected pitch. .PP .\" .\" .\" .SH EXAMPLES .\" Send a string of characters at 25 WPM, 700Hz, with no extra gaps: .IP echo "UNIX CW SOUNDER" | cw \-w 25 \-t 700 .PP Send a string at varying speeds and tones on the console speaker, specifying a system console device: .IP echo "%W12;%T400;400HZ 12WPM %W25;%T1500;1500HZ 25WPM" | cw \-m \-sc \-d /dev/tty2 .PP Send C-cedilla, VA, and a report of the WPM setting, with extra spacing at half volume: .IP echo "[CE] [VA] %>W" | cw \-g 10 \-v 50 .PP .\" .\" .\" .SH ERRORS AND OMISSIONS .\" Cut numbers are not provided, though they can be emulated, up to a point, by pre-filtering. .PP An output to an optional external device, for example, keying a line on the parallel port, or a serial line, might also be useful. .PP .\" .\" .\" .SH SEE ALSO .\" Man pages for \fBcw\fP(7,LOCAL), \fBlibcw\fP(3,LOCAL), \fBcwgen\fP(1,LOCAL), \fBcwcp\fP(1,LOCAL), and \fBxcwcp\fP(1,LOCAL). .\" unixcw-3.5.0/src/cw/Makefile.am0000644000175000017500000000366512451005455016125 0ustar acerionacerion# Copyright (C) 2001-2006 Simon Baldwin (simon_baldwin@yahoo.com) # Copyright (C) 2011-2015 Kamil Ignacak (acerion@wp.pl) # # This program is free software; you can redistribute it and/or # modify it under the terms of the GNU General Public License # as published by the Free Software Foundation; either version 2 # of the License, or (at your option) any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

If defined, these options are used first; command line options take precedence. .PP .\" .\" .\" .SH DESCRIPTION .\" .PP \fBcwcp\fP is a curses-based interactive Morse code tutor program. It allows menu selection from a number of sending modes, and also permits character sounding options, such as the tone pitch, and sending speed, to be varied from the keyboard using a full-screen user interface. .PP .\" .\" .\" .SS COMMAND LINE OPTIONS .\" .B cwcp understands the following command line options. The long form options may not be available in non-LINUX versions. .TP .I "\-s, \-\-system=SYSTEM" Specifies the way that \fBcwcp\fP generates tones. Valid values are: \fInull\fP for no tones, just timings, \fIconsole\fP for tones through the console speaker, \fIalsa\fP for tones generated through the system sound card using ALSA sound system, \fIoss\fP for tones generated through system sound card using OSS sound system, \fIpulseaudio\fP for tones generated through system sound card using PulseAudio sound system, \fIsoundcard\fP for tones generated through the system sound card, but without explicit selection of sound system. These values can be shortened to 'n', 'c', 'a', 'o', 'p', or 's', respectively. The default value is 'pulseaudio'. .TP .I "\-d, \-\-device=DEVICE" Specifies the device file to open for generating a sound. \fBcwcp\fP will use default device if none is specified. The default devices are: \fI/dev/console\fP for sound produced through console, \fIdefault\fP for ALSA sound system, \fI/dev/audio\fP for OSS sound system, \fIa default device\fP for PulseAudio sound system. See also \fINOTES ON USING A SOUND CARD\fP below. .TP .I "\-w, \-\-wpm=WPM" Sets the initial sending speed in words per minute. The value must be between 4 and 60. The default value is 12 WPM. .TP .I "\-t, \-\-tone=HZ" Sets the initial sounder pitch in Hz. This value must be between 0 and 4,000. A value of 0 selects silent operation, and can be used for timing checks or other testing. The default value is 800Hz, .TP .I "\-v, \-\-volume=PERCENT" Sets the initial sending volume, as a percentage of full scale volume. The value must be between 0 and 100. The default value is 70 %. Sound volumes work fully for sound card tones, but \fBcwcp\fP cannot control the volume of tones from the console speaker. In this case, a volume of zero is silent, and all other volume values are simply sounded. .TP .I "\-g, \-\-gap=GAP" Sets the initial extra gap, in dot lengths, between characters (the 'Farnsworth' delay). It must be between 0 and 60. The default is 0. .TP .I "\-k, \-\-weighting=WEIGHT" Sets the initial weighting, as a percentage of dot lengths. It must be between 20 and 80. The default is 50. .TP .I "\-T, \-\-time=TIME" Sets the initial practice time, in minutes. \fBcwcp\fP stops after generating random Morse code for this period. The value must be between 1 and 99. The default is 15 minutes. .TP .I "\-f, \-\-infile=FILE" Specifies a text file that \fBcwcp\fP can read to configure its practice text. See \fICREATING CONFIGURATION FILES\fP below. .TP .I "\-F, \-\-outfile=FILE" Specifies a text file to which \fBcwcp\fP should write its current practice text. .\".TP .\".I "\-c, \-\-colours, \-\-colors" .\"This option specifies an initial colour set for \fBcwcp\fP. The colour .\"set is specified as four integers, in the range 0 to 7, separated by .\".\"commas. These integers set the display foregrounds, the display .\"backgrounds, the box foregrounds, and the box backgrounds. The .\"available colours are, in order, black, red, green, yellow, blue, .\"magenta, cyan, and white. The default colour set is "7,4,7,0". .\"If \fI\-m\fP or \fI\-\-mono\fP is given, this option is ignored. .\".TP .\".I "\-m, \-\-mono" .\"This option tells \fBcwcp\fP not to attempt to produce a colour .\"display. Where colours are not possible, or monochrome .\"requested, \fBcwcp\fP will use reverse video within its windows to .\"create its interface. If this option is given, any \fI\-c\fP .\"or \fI\-\-colours\fP is ignored. .TP .I "\-h, \-\-help" Prints short help message. .TP .I "\-V, \-\-version" Prints information about program's version, authors and license. .PP .\" .\" .\" .SS USER INTERFACE .\" \fBcwcp\fP is a curses-based program that takes over the complete operation of the terminal on which it is run. If colours are available on the terminal, it will produce a colour interface. .PP The \fBcwcp\fP screen is divided into several distinct areas: .TP .I "The Menu Selection window" The Menu Selection window shows the main modes that \fBcwcp\fP offers. Use the \fIF10\fP and \fIF11\fP or \fIKEY_DOWN\fP and \fIKEY_UP\fP keys to select the mode. \fIF9\fP or \fIReturn\fP start sending, and \fIF9\fP again or \fIEsc\fP stop sending. Changing mode also stops sending. .TP .I "The Morse Code Display window" This window displays each Morse code character after it has been sent. .TP .I "The Speed Control window" The Speed window shows the current Morse code sending speed in words per minute. Pressing the \fIF2\fP or \fIKEY_RIGHT\fP keys increases the speed; pressing the \fIF1\fP or \fIKEY_LEFT\fP keys decreases the speed. .TP .I "The Tone Control window" This window shows the current Morse code tone pitch. Use the \fIF4\fP or \fIKEY_HOME\fP key to increase the pitch, and the \fIF3\fP or \fIKEY_END\fP key to decrease it. Values change in steps of 20Hz. .TP .I "The Volume Control window" This window shows the current Morse code volume. Use the \fIF6\fP key to increase the volume, and the \fIF5\fP key to decrease it. Values change in steps of 1%. Note that \fBcwcp\fP cannot control the volume of the console speaker, so the volume control only works effectively for tones generated on the sound card. .TP .I "The Gap Control window" This window shows the current additional 'Farnsworth' gaps to be appended after each Morse code character is sounded. Use \fIF8\fP to increase the gap, and \fIF7\fP to decrease it. .TP .I "The Time Control window" This window shows the selected practice time. After generating Morse code in a particular mode for this amount of time, \fBcwcp\fP stops automatically. Use \fIKEY_NPAGE\fP to increase the time, and \fIKEY_PPAGE\fP to decrease it. During sending, the value in this window counts down to one, and after final minute of sending has elapsed, \fBcwcp\fP stops sending. The timer operates like a microwave or kitchen timer; it counts down on its own, but the time remaining can also be altered manually while the timer operates. .PP The following keys vary the screen colours: .TP .I "{ key" Changes the foreground colour of the window boxes. .TP .I "} key" Changes the background colour of the window boxes. .TP .I "[ key" Changes the foreground colour of the window contents. .TP .I "] key" Changes the background colour of the window contents. .PP Eight screen colours are available for each: black, red, green, yellow, blue, magenta, cyan, and white. Use a key to cycle round these colours for the particular part of the display controlled by that key. On a change of colours, the complete screen is repainted. .PP Use \fICtrl\-L\fP to repaint the complete screen, in case of screen corruption. Use \fICtrl\-V\fP to clear the Morse Code Display Window. This command is available only when \fBcwcp\fP is not sending. .PP To leave \fBcwcp\fP, press \fIF12\fP or \fICtrl-C\fP, or select \fIExit\fP on the mode menu. .PP All of the above command keys may be used while random characters are being sent, and when keyboard input is being sent. .PP If function keys are not available on the terminal, \fICtrl-\fP combinations can be used. On the top row of letter keys on the keyboard, the keys \fICtrl-Q\fP to \fICtrl-I\fP may be used as alternatives for \fIF1\fP to \fIF8\fP, and on the second row of letter keys, \fICtrl-A\fP to \fICtrl-F\fP as alternatives for \fIF9\fP to \fIF12\fP. For \fIKEY_PPAGE\fP and \fIKEY_NPAGE\fP, use \fICtrl-O\fP and \fICtrl-P\fP. .PP .\" .\" .\" .SS RANDOM CHARACTERS AND WORDS .\" .B cwcp sends random characters in groups of five, with a space between each group. After a period of sending, set in the \fITime Control window\fP, \fBcwcp\fP stops automatically. It can also be stopped manually, before this time period expires. .PP When sending random words, \fBcwcp\fP sends the complete word, followed by a space. Because short words are easier to copy without writing, \fBcwcp\fP's default dictionary contains only three, four, and five-letter words in its random words list. .PP .B cwcp chooses at random from a list of around 3000 words in its default dictionary. You can change this text using a configuration file, read at startup. See \fICREATING CONFIGURATION FILES\fP below. .PP .\" .\" .\" .SS NOTES ON USING A SOUND CARD .\" By default, \fBcw\fP tries to open default PulseAudio. If PulseAudio server is not accessible, cw tries to open OSS device "/dev/audio" to access the system sound card. This is generally the correct device to use, but for systems with special requirements, or those with multiple sound cards, the option \fI-d\fP or \fI\-\-device\fP, combined with \fI-s\fP or \fI\-\-system\fP can be used to specify the device and audio system for sound card access. If the sound card device cannot be set up, \fBcwcp\fP prints the error message .IP cannot set up soundcard sound .PP and exits. .PP Sound card devices, when opened through OSS sound system, are usually single-access devices, so that when one process has opened the device, other processes are prevented from using it. In such cases \fBcwcp\fP will of course conflict with any other programs that expect exclusive use of the system sound card (for example, MP3 players). If \fBcwcp\fP finds that the sound card is already busy, it prints the error message .IP open /dev/audio: Device or resource busy .PP and exits. .PP .\" The main sound card device will often allow \fBcwcp\fP to control tone .\" volumes directly, but where this is not possible, \fBcwcp\fP uses the .\" mixer device instead. By default, this is "/dev/mixer", but the device .\" can be specified with the \fI-y\fP or \fI\-\-mdevice\fP options. In .\" general, as with the main sound card device, the default mixer device .\" is usually the correct one to use. .\" .PP .\" The mixer device is only used if the sound card does not allow volume .\" control through the main sound card device. .PP The sound card device is not used if \fBcwcp\fP is only sending tones on the console speaker. .PP .\" .\" .\" .SS AUDIO OUTPUT \- DEFAULTS AND SELECTION .\" \fBcwcp\fP first tries to access sound card using PulseAudio sound system, using default device name, unless user specifies other audio device with option \fI-d\fP or \fI\-\-device\fP. .PP \fBcwcp\fP then tries to access sound card using OSS audio system and default OSS audio device name ('/dev/audio'), unless user specifies other audio device with option \fI-d\fP or \fI\-\-device\fP. .PP If opening soundcard through OSS fails, \fBcwcp\fP tries to access the sound card using ALSA audio system, and default ALSA audio device name ('default'), unless user specifies other audio device with option \fI-d\fP or \fI\-\-device\fP. .PP If opening soundcard through ALSA also fails, \fBcwcp\fP tries to access system console buzzer using default buzzer device '/dev/console', unless user specifies other audio device with option \fI-d\fP or \fI\-\-device\fP. .PP It is very common that in order to access the console buzzer device user has to have root privileges. For that reason trying to open console buzzer almost always fails. This is not a program's bug, this is a result of operating system's restrictions. Making \fBcwcp\fP an suid binary bypasses this restriction. The program does not fork() or exec(), so making it suid should be relatively safe. Note however that this practice is discouraged for security reasons. .PP As stated, user can tell \fBcwcp\fP which device to use, using \fI-d\fP or \fI\-\-device\fP option. Which device files are suitable will depend on which operating system is running, which system user ID runs \fBcwcp\fP, and which user groups user belongs to. .PP .\" .\" .\" .SS CREATING CONFIGURATION FILES .\" \fBcwcp\fP contains a default set of modes and practice text that should be enough to begin with. It can however read in a file at startup that reconfigures these to provide different character groupings, word sets, and other practice data. .PP To read a configuration file, use the \fI-f\fP or \fI\-\-infile\fP command line options. The file should introduce each \fBcwcp\fP mode with a section header in '[' ... ']' characters, followed by the practice text for that mode, with elements separated by whitespace. Lines starting with a semicolon or hash are treated as comments.

As a starting point for customized modes, \fBcwcp\fP will write its default configuration to a file if given the undocumented \fI-#\fP option, for example "cwcp -# /tmp/cwcp.ini". .\" .\" .\" .SH NOTES .\" .B cwcp owes its existence to the DOS Morse code tutor CP222C.EXE, by VU2ZAP. CP222C.EXE seemed to offer the right range of facilities for learning Morse code in a simple, easy-to-use, and compact package. \fBcwcp\fP is very much modeled on that DOS program, and should prove useful both for learning the code, and for experienced CW users who want, or need, to improve their receiving speed. .PP Curses may impose a delay when recognizing the \fIEsc\fP key alone, as this character is often the first of a sequence generated by a function key. \fBcwcp\fP responds instantly to \fIF9\fP. .PP The characters echoed in the Morse Code Display window may be ASCII representations of Morse procedural signals; see the \fBcw\fP(7,LOCAL) man page for details. .PP .\" .\" .\" .SS HINTS ON LEARNING MORSE CODE .\" Here are a few hints and tips that may help with the process of learning Morse code. .PP Firstly, do \fBNOT\fP think of the elements as dots and dashes. Instead, think of them as dits and dahs (so 'A' is di-dah). If you think of them in this way, the process of translating sound into characters will be learned much more easily. .PP Do not learn the characters from a table. Learn them by watching the groups appear on the screen, and listening to the sounds produced as each is sent. In the very initial stages, it may be beneficial if you can find a person to take you through the first stages of recognizing characters. .PP Do not waste your time learning Morse code at 5 WPM. Set the speed to 12 or 15 WPM, but use extra spacing (the Gap window) to reduce the effective speed to much lower - around four or five WPM \fIeffective\fP speed. This way, you will learn the rhythm of the characters as they are sent, but still have plenty of time between characters. As you practice, decrease the gap to zero. .PP Learn in stages. Start by learning the \fIEISH5\fP group, then progress down through the menu as each group is mastered. The groups contain characters which are in some way related, either by sound, or by type of character. .PP .\" \[u0022] = ", otherwise emacs syntax highlighting is messed up; Once you have completed all the groups \fIEISH5\fP to \fI\[u0022]'$(+:_\fP (or \fI23789\fP if you do not want to learn procedural signals yet), use the full character set options, and the words and CW words options, to sharpen your skill. If you have difficulties with particular characters, return to that group and practice again with a smaller character set. .PP Resist the temptation to try to learn or improve your speed by copying off-air. You will not know what speed you are working at, and much hand-sent Morse is not perfectly formed. What you can gain off-air though is a general 'resilience', a tolerance for Morse code where the timing of individual elements, or spacing between characters and words, is not 100% accurate. .PP If working to attain a particular speed for a test, always set the speed slightly higher. For example, if aiming for 12 WPM, set the tutor speed to 14 or 15 WPM. This way, when you drop back to 12 WPM you will feel much more relaxed about copying. Be aware that \fBcwcp\fP is not necessarily going to send at exactly the speed you set, due to limitations in what can be done with UNIX timers. It often sends at a slower speed than you set, so be very careful with this if you have a target speed that you need to reach. .PP Use the program to make cassette tapes that you can take with you in a walkman or in the car, for long journeys. You do not have to write down everything you hear to practice Morse code. Simply listening to the shapes of characters over a period will help to train your brain into effortless recognition. In fact, slavishly writing everything down becomes a barrier at speeds of 15-20 WPM and above, so if you can begin to copy without writing each character down, you will find progress much easier above these speeds. But do not over-use these tapes, otherwise you will quickly memorize them. Re-record them with new contents at very regular intervals. .PP Try to spend at least 15-30 minutes each day practicing. Much less than this will make progress glacially slow. But significantly more than an hour or so may just result in you becoming tired, but not improving. Recognize when it is time to stop for the day. .PP Do not worry if you reach a speed 'plateau'. This is common, and you will soon pass it with a little perseverance. .PP At higher speeds, CW operators tend to recognize the 'shape' of whole words, rather than the individual characters within the words. The CW words menu option can be used to help to practice and develop this skill. .PP .\" .\" .\" .SH ERRORS AND OMISSIONS .\" The calibration option is a bit ropy. It simply sends PARIS repeatedly, and relies on you to time the sending and then work out if any adjustment to the speed is really necessary. Automatic calibration by making measurements over a given period would be a lot better. .PP Generating random CW QSOs would be fun to do. .PP A facility to allow a user to key Morse into the system, and to have it send code, and measure the accuracy of keying, would be nice. .PP .\" .\" .\" .SH SEE ALSO .\" Man pages for \fBcw\fP(7,LOCAL), \fBlibcw\fP(3,LOCAL), \fBcw\fP(1,LOCAL), \fBcwgen\fP(1,LOCAL), and \fBxcwcp\fP(1,LOCAL). .\" unixcw-3.5.0/src/cwcp/cwcp.c0000644000175000017500000012035412604554042015510 0ustar acerionacerion/* * Copyright (C) 2001-2006 Simon Baldwin (simon_baldwin@yahoo.com) * Copyright (C) 2011-2015 Kamil Ignacak (acerion@wp.pl) * * This program is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public License * as published by the Free Software Foundation; either version 2 * of the License, or (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs.

Moreover, depending on platform and software/files installed on build machine, the build system will configure and compile following features: - cwcp, if ncurses development files are available; - xcwcp, if QT5 development files are available (xcwcp is an application written in C++); libcw library, and cw and cwgen applications are built unconditionally. You can explicitly disable some libcw and unixcw features by passing flags to configure script. See output of "./configure --help" for details. Check your platform-dependent documentation on what packages/files are needed for each of these features. Build-time requirements for unixcw: - standard build environment to build software from source package with "./configure && make && make install"; - GNU make may be necessary on some platforms (I've had a problem with FreeBSD's make on FreeBSD 9.3; make on FreeBSD 10.0 worked fine). If, when running "make", you see an error message like this: *** Parse error in unixcw-3.4.0/src: Need an operator in '../Makefile.inc' (Makefile:640) *** Error 1 in unixcw-3.4.0 (Makefile:416 'all-recursive') then install gmake package, and try running "gmake & gmake install" instead of "make & make install". - pkg-config to get configuration flags for QT5 application (xcwcp); you can override pkg-config settings for QT5 using environment variables, see output of "./configure --help" for details. - audio library development files for including support for OSS, ALSA and PulseAudio audio sinks in libcw; - header file providing KIOCSOUND symbol for including support for console buzzer in libcw. - ncurses development files for building cwcp; - QT5 development files for building xcwcp; unixcw 3.4.2 (or at least parts of it) was successfully compiled on following platforms: - Debian GNU/Linux 8 jessie/sid, x86_64, gcc 4.9.2; - Alpine Linux 3.1, x86_64, gcc 4.8.3, musl 1.1.5; - FreeBSD 10.0, x86_64, clang 3.3; unixcw 3.4.1 (or at least parts of it) was successfully compiled on following platforms: - Debian GNU/Linux jessie/sid, x86_64, gcc 4.9.1; unixcw 3.4.0 (or at least parts of it) was successfully compiled on following platforms: - Debian GNU/Linux jessie/sid, x86_64, gcc 4.9.1; - FreeBSD 10.0 (x86_64-unknown-freebsd10.0, with clang 3.3); - FreeBSD 9.3 (freebsd9.3 with gcc 4.2.1); - OpenBSD 5.5 (amd64-unknown-openbsd5.5 with gcc 4.2.1); compilation on OpenBSD gives lots of warnings related to usage of functions deemed unsafe by OpenBSD developers, but there are no errors. There are also some warnings about redeclarations of some functions - this still needs to be fixed. These were project-specific instructions. Generic instructions are below. Basic Installation ================== These are generic installation instructions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, a file `config.cache' that saves the results of its tests to speed up reconfiguring, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.in' is used to create `configure' by a program called `autoconf'. You only need `configure.in' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. If you're using `csh' on an old version of System V, you might need to type `sh ./configure' instead to prevent `csh' from trying to execute `configure' itself. Running `configure' takes awhile. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package. 4. Type `make install' to install the programs and any data files and documentation. 5. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. You can give `configure' initial values for variables by setting them in the environment. Using a Bourne-compatible shell, you can do that on the command line like this: CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure Or on systems that have the `env' program, you can do it like this: env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you must use a version of `make' that supports the `VPATH' variable, such as GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. If you have to use a `make' that does not supports the `VPATH' variable, you have to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. Installation Names ================== By default, `make install' will install the package's files in `/usr/local/bin', `/usr/local/man', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PATH'. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you give `configure' the option `--exec-prefix=PATH', the package will use PATH as the prefix for installing programs and libraries. Documentation and other data files will still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=PATH' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Optional Features ================= Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Specifying the System Type ========================== There may be some features `configure' can not figure out automatically, but needs to determine by the type of host the package will run on. Usually `configure' can figure that out, but if it prints a message saying it can not guess the host type, give it the `--host=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name with three fields: CPU-COMPANY-SYSTEM See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the host type. If you are building compiler tools for cross-compiling, you can also use the `--target=TYPE' option to select the type of system they will produce code for and the `--build=TYPE' option to select the type of system on which you are compiling the package. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Operation Controls ================== `configure' recognizes the following options to control how it operates. `--cache-file=FILE' Use and save the results of the tests in FILE instead of `./config.cache'. Set FILE to `/dev/null' to disable caching, for debugging `configure'. `--help' Print a summary of the options to `configure', and exit. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--version' Print the version of Autoconf used to generate the `configure' script, and exit. `configure' also accepts some other, not widely useful, options. unixcw-3.5.0/ChangeLog0000644000175000017500000010755112604554041014442 0ustar acerionacerion2015-09-29 Kamil Ignacak * bugfix: fixing code that resets tone queue on flushing. A bug was found on FreeBSD: after pressing Ctrl+C, application that wanted to stop and delete generator as part of SIGINT handling procedure, got stuck in cw_tq_flush_internal() function, waiting for tone queue to go idle. This never happened. Resetting all tone queue state variables in flush function ensures that the function completes and returns, and that client application can exit. 2015-09-12 Kamil Ignacak * xcwcp: the application souce code files are now ported to Qt5. Build system files have been modified to use Qt5 to build xcwcp. Discovery and adding -fPIC to compiler flags for xcwcp is right now very naive, perhaps that will have to be improved in the future. 2015-09-09 Kamil Ignacak * alternative IPC: now that we have experimental branch, I decided to remove "alternative IPC" code from master branch and leave that just in "experimental" branch. master will be for small very incremental, and only necessary changes. At this point libcw code in master looks pretty much like it was in around commit d02491ee32668d5f5ca3904193f306956e72468d, i.e. pre-semaphores. 2015-09-08 Kamil Ignacak * git: created experimental_receiver branch, where all changes related to new ideas for receiver will be developed. master branch will be for boring, non-experimental code. 2015-09-03 Kamil Ignacak * xcwcp: fixed handling of backspace key in keyboard mode. For some time now the backspace key didn't remove yet-unplayed characters from text area. Now the key works correctly. 2015-09-01 Kamil Ignacak * xcwcp: simplifying class design in display.h. The file is now called textarea.h, the class/widget derived from QTextEdit is now called TextArea, and the change is reflected in few of xcwcp's source files. I hope to have less work in future thanks to this simplification. A bit less code to maintain, a bit less logic to understand. 2015-08-31 Kamil Ignacak * xcwcp: beginning of review of the the code, refactoring, updating comments. 2015-08-30 Kamil Ignacak * libcw/signals: improving signals code already existing in cw_gen and cw_tq modules. In particular change in cw_gen (in dequeue_and_play_internal()) greatly improves correctness of usage of semaphores so far. Fixing a FIXME in cw_tq_wait_for_tone_internal(): using new semaphore deq_semaphore for another aspect of communication between tq and generator makes the function fully ready for use of alternative IPC mechanism (the function doesn't need signals anymore). * libcw/ipc: adding new header file for new libcw module: libcw_ipc (Inter Process Communication). For now the module consists only of a header file with a single macro. * libcw/ipc: implementing cw_tq_wait_for_level_internal() using semaphores. Improving the part of cw_tq_wait_for_tone_queue_internal that used semaphores. This means that tq module can work without signals, with semaphores only. * libcw/tests: adding test_cw_tq_wait_for_level_internal() unit test function 2015-08-28 Kamil Ignacak * libcw/signals: Initial commit of semaphores code. The code enables communication between generator and tone queue using semaphores instead of signals. It may be desirable for libcw library to not to use signals, so that client application can use them freely, without any interference between application and libcw. This is the first step to replace signals with other IPC mechanisms. This alternative mechanism may be enabled with "--enable-signals-alternative" passed to ./configure script. 2015-08-02 Kamil Ignacak * tests: moving selected "make" test build targets from src/libcw/Makefile.am to src/libcw/tests/Makefile.am. Updating flags for some of the targets, so they may be built a bit differently * tests: libcw_test_public.c no longer tests "forever" feature. Since this is a test of public API, it shouldn't use LIBCW_UNIT_TESTS flag for compilation, nor should it use any internal or test functions. 2015-07-31 Kamil Ignacak * gen/tq: creating small client application that tests for presence of the problem described on 2015-07-29 ("short space" problem). The client application is located in src/libcw/tests/ and is executed as part of standard test suite ("make check"). 2015-07-29 Kamil Ignacak * gen/tq: one more attempt in cw_gen_play_eow_space_internal() to ensure that eow spaces are enqueued so that client software can have tq low level threshold set to 1. It should be stressed in release notes that client software cannot assume that eow space will be one tone. There may have been such implicit assumption in the past, but it was only implicit, and it became invalid some time ago. 2015-06-14 Kamil Ignacak * pre-release: updating information in selected files before release (updating version numbers, adding notes new releases etc.) 2015-03-19 Kamil Ignacak * fixes: Few minor changes in main code and test code that solve problems found during tests on FreeBSD 10. 2015-03-13 Kamil Ignacak * generator: fixing one possible cause of segfaults: limiting number of executions of cw_gen_silence_internal() function that somewhere down in call stack also called pthread_kill(). On some occasions (during library cleanup) the thread id passed to pthread_kill becomes invalid, and any subsequent calls to cw_gen_silence_internal() resulted in segfault. I have discovered this problem when testing src/cw/cw on Alpine Linux. Other parts of unixcw package may have been affected by this problem as well. I don't know how old the problem was (since when it was possible to create segfaults when exiting from cw on Alpine Linux). The fix was tested on Alpine Linux and on Debian GNU/Linux. 2015-03-10 Kamil Ignacak * tests: testing unixcw on Alpine Linux (with musl libc). Fixing problems in cw_oss and cw_gen modules. One important change in libcw made during tests on Alpine Linux: generator's thread function is now a joinable thread (it was a detached thread until now). I don't think that it will have any impact on libcw's client code, but I thought that I should mention this in ChangeLog. Also adding one (unit ?) test function to libcw_test_internal. 2015-03-05 Kamil Ignacak * cw_gen: today I've added second and third brand new unit test function for cw_gen module in libcw_gen.c file. At the beginning of this development cycle there were zero functions defined in libcw_gen.c (there were, and still are, functions testing cw_gen module in libcw_test_public.c). I think that's a progress :) During creation of these functions I had an opportunity to improve code and comments of generator's base functions. 2015-03-04 Kamil Ignacak * asserts: base libcw is now compiled with -DNDEBUG flag by default (asserts are "off"). The asserts are still "on" by default in "unit tests" libcw. Asserts are switched "on" in base libcw with "./configure --enable-dev". 2015-03-02 Kamil Ignacak * generator: First unit test intended to be executed on building "make check" target. The unit test function uncovered one error: when a generator is created, then is *not* started, and then is deleted, libcw called pthread_kill(&id, ...) on uninitialized id in cw_gen_delete(). This caused a program to crash. This has been fixed by adding a flag to cw_gen_t and additional code in cw_gen.c. 2015-02-25 Kamil Ignacak * tq: improving handling of tones in general, and "forever" tones in particular. I have created CW_TONE_INIT and CW_TONE_COPY macros that (re-)initialize a tone variable (all of its fields), and that copy values of fields from one cw_tone_t variable to other. There are so many places where I need to set values of fields of cw_tone_t, that I thought it would be beneficial to have some sort of constructor/initializer. A full constructor that mallocs() tone would be too much, but simple macro doing assignments is quite ok. Until now the tone queue manager and generator used special value CW_AUDIO_FOREVER_USECS assigned to cw_tone_t.usecs to indicate that a tone is "forever" tone. This had one downside: a regular, plain variable had special value that I had to constantly be aware of. Now the "usecs" is again a regular variable - nothing more than the length of tone. Information whether or not a tone is "forever" tone is now conveyed by new field in cw_tone_t: cw_tone_t.forever. 2015-02-23 Kamil Ignacak * cw_gen: Lots of small updates. Mostly in comments, but I have also removed few unused (commented out) lines of code and renamed some internal functions. One noticeable change was in cw_generator_set_tone_slope() - some corner cases of handling function's arguments were cleared in function's top level comments, and implementation has been updated accordingly. 2015-02-22 Kamil Ignacak * key, generator, tone queue: Small improvements at intersection of these modules. One example: after changing third argument to cw_key_ik_enqueue_symbol_internal(), the function no longer has to explicitly refer to length of Space/Dot/Dash stored in generator. Enqueueing symbols with proper length is now exclusively job of generator (at least in case of this function call). Also modifying names of some variables (so that they follow a convention used already in receiver) and functions (so that their purpose is more obvious). So in a nutshell: small improvements in key, generator and tone queue. 2015-02-22 Kamil Ignacak * libcw.c: after populating the file with "global" functions for generator, tone queue and receiver modules, I have also moved here the "global" functions from cw_key module. At this point the file contains definitions of global variables cw_receiver, cw_generator and cw_key (cw_key is static in this file). 2015-02-19 Kamil Ignacak * libcw.c: I have (re)created the file. It will contain all the functions that use global variables cw_generator, cw_receiver and maybe cw_key as implicit arguments. After moving such functions from other modules into libcw.c, other modules major should be completely free of global variables, and should only contain functions that operate on generators, receivers and keys as explicit function arguments. Then the function will have the old interface, and the new interface. And it will be easy to have multiple generators (or receivers) in the same application. 2014-12-30 Kamil Ignacak * valgrind: running valgrind on libcw_test_internal reveals few small problems in test code, and one small problem in "production" code. Fixing the problems. Thanks valgrind! 2014-12-20 Kamil Ignacak * tests: moving as much code as possible from libcw_test_public.c to respective module files. The tests that are still in libcw_test_public.c test library functions that depend on different modules (mostly tone queue and generator). Those library functions that can be tested in separation are tested in their module files. This should shorten the libcw_test_public.c file and ensure that test functions are defined as close to library functions as possible, so that library code and related test code are grouped together (thus improving modularization of library). There is still some work to be done in this area, but a good progress has been made. In the process of moving test functions to their modules, some test functions have been improved a bit. 2014-12-02 Kamil Ignacak * tests: improving unit tests for receiver module. The receiver's test code from libcw_test_public.c is being slowly moved to libcw_rec.c. receiver module is fairly independent from a generator or audio sinks, so it's ok to mat the tests internal in the libcw_rec.c file. They can be executed with simple "make check", and the execution takes very little time. 2014-11-28 Kamil Ignacak * tests: improving unit tests for receiver module. Working on functions that will automatically generate test data (input data for cw_start_receive_tone() and cw_end_receive_tone() functions) with different parameters 2014-11-24 Kamil Ignacak * tests: Test executables for libcw now accept -m option, which allows me to specify libcw module(s) to be tested. Option's values are: 'r' - receiver 't' - tone queue 'g' - generator 'k' - Morse key 'o' - other * cwutils: reformatting code in src/cwutils/cmdline.c. No functional changes. 2014-11-19 Kamil Ignacak More changes in receiver module. Refactoring and moving public functions' code to _internal() functions that accept pointer to receiver as first argument. Updating comments. If you depend on Receiver State names (strings starting with RS_) printed by library's debug messages, you may want to check changed values of RS enum and corresponding strings on top of libcw_rec.c - they have been changed. Making some terminology changes in libcw_rec.c - some things are now named in more consistent way (variable names, names of things). 2014-11-12 Kamil Ignacak Proceeding with changes, simplifications and refactoring in receiver module. Generator module is also affected. 2014-11-11 Kamil Ignacak Creating new module: libcw_rec. Moving code related to receiver from libcw.c to libcw_rec.c. Moving other code from libcw.c to other modules. libcw.c has been emptied and is now removed. 2014-08-17 Kamil Ignacak * build system: changes in build system files (configure.ac and src/libcw/Makefile.am) introduced to improve compilation on OpenBSD 5.5. 2014-08-16 Kamil Ignacak * README: reviewed contents of README file. Lots of stuff accumulated in the file over the time, making a first-to-read document a bit too large. Moved parts of the file to INSTALL, THANKS and HISTORY files. * INSTALL: reviewed contents of INSTALL file. Less unnecessary sentences, more details. Also added a generic installation instructions as usually found in INSTALL files. * files: added new files to dist package: THANKS HISTORY added new files to git repository only: qa_build_debian.sh qa_compile_headers.sh qa_test_configure_flags.sh (well this one is moved from ./tools) qa_valgrind_cwcp.sh 2014-08-12 Kamil Ignacak * libcw/utils: three more functions have been moved to libcw_utils: cw_version, cw_license and cw_get_audio_system_label, because, well, these functions look like utility functions. * libcw/signal: I couldn't resist and I moved signal-related functions from libcw.c to new module: libcw_signal. Bodies of these functions have not been modified, so you can compare contents of libcw_signal.c with contents of libcw.c from last release to see how the move has been done. * libcw/generator: I have moved some more code from libcw.c to libcw_gen.c. There is still some generator-related code left in libcw.c, but I promise not to touch it in this release. I think that I have enough of moving code. There is still some code left in libcw.c. Big part of this code is related to receiver. The next big task in my work on libcw should be understanding (or at least attempting to understand) the receiver code and its relation to other modules (especially to libcw_gen and libcw_key modules). Receiver code is one of last areas that I haven't really tried to digest. 2014-08-07 Kamil Ignacak * QT4: Simplifying configuration of QT4 in configure.ac: using PKG_CHECK_MODULES instead of custom shell script. Tests on Linux and FreeBSD ongoing. * FreeBSD & clang 3.3: successful build of "make check" target. Successful execution of libcw_test_simple_gen and libcw_test_internal. Tests on FreeBSD ongoing. 2014-08-06 Kamil Ignacak * FreeBSD: I managed to configure and build the package on FreeBSD 10. It worked! I only had to slightly adjust configure.ac and src/libcw/Makefile.am (dl library). There is still a bit of work on FreeBSD left to do in configure.ac. * OSS: During tests of OSS on FreeBSD I've found a bug that prevented libcw from correctly opening OSS sink (unnecessary function call). This bug has been fixed. This fix should affect Linux and FreeBSD. 2014-08-02 Kamil Ignacak * libcw/key: lots of changes in libcw_key module. After some trials and errors I've implemented a code with single data type for all types of code (cw_key_t) while maintaining separate states of straight key, iambic keyer, and tone-queue-key. The key and code handling it is not visible to users of public API. Behaviour of public API functions has not been changed. 2014-07-28 Kamil Ignacak * libcw: I think that for now I'm done with splitting libcw.c into parts. In about a week I have moved large portions of code from libcw.c to separate files. Different parts of libcw.c, implementing different functionality, are now in their own *.c/*.h files. These new modules are: libcw_data.c libcw_gen.c libcw_key.c libcw_tq.c libcw_utils.c It's very possible that in future I will move some more code from libcw.c to new files. Up until now the code in new files is pretty much the same as it was in libcw.c (the same order of functions, the same bodies of functions, pretty much copy-and-paste). If you want to check correctness of moving the functions to new files, you could do this by comparing libcw/*.c files from 28.07.2014 with original libcw.c from previous release (I did such comparing using KDE application 'kompare', everything looks ok to me). After today I may make some changes in *.c files that will make the movement of code less transparent (but of course keeping everything in git). In addition to moving parts core functionality of the library from libcw.c to new files, I have also reviewed test code and build targets in Makefile.am for building test applications. You can now build three test executables with "make check": libcw_test_internal libcw_test_public libcw_test_simple_gen C code used to build these test executables is now a bit more simple - it uses a bit less #ifdefs, and main() function for each executable is in its own separate *.c file. There is no main() function in libcw.c file anymore. The main goal for the splitting of libcw.c was to introduce more order into the project. libcw.c file contained almost 10k LOC. Almost all modules (with exception of audio systems) were in a single file. Functions implementing these modules were sometimes mixed. Mental navigation in the file was becoming difficult. The split should help me solve these problems. The description above was given to explain why and how the libcw.c has been modified so heavily in this release. The code is still in *.c files. No functionality has been removed. No functions have been added or removed. Looking from outside, the library hasn't changed. It has the same set of functions implementing the same functionality. The libcw.h and libcw_debug.h files haven't changed at all. Changes to libcw in this release, from users' and developers' point of view, are none. 2014-07-26 Kamil Ignacak * cwcp: fixing a stupid error that I introduced in one of previous releases: cwcp didn't use "combined" argv, so it didn't process CWCP_OPTIONS from env. Now it should work. Today's commit ends my main part of work on cwcp code. There were three main changes made to cwcp: first: fixing the bug mentioned above; second: calling few delwin()s to plug memory leaks; third: bringing the code into shape when it comes to project's indentation and comments style. 2014-07-23 Kamil Ignacak * libcw/test code: moving some code related to testing from libcw.c into other files. This little change triggered a larger change in test utilities for libcw. Now we have three libcw test executables built with "make check": libcw_test_internal, libcw_test_public, and libcw_test_simple. Each of them has its own .c file with its own main(). There is no main() function in libcw.c anymore. Explicit "standalone" target has been removed from src/libcw/Makefile.am. It has been replaced by libcw_test_simple executable built with "make check". 2014-07-22 Kamil Ignacak * libcw/keying code: Moving most of code related to iambic keyer, straight key, and general keying control into new file: libcw_key.c. Having separate things in separate files (instead of having everything in a single 10kLOC file) should make some things easier for me as a maintainer of libcw. 2014-07-21 Kamil Ignacak * libcw/tone queue: Moving most of code related to tone queue into new file: libcw_tq.c. * libcw/data: Moving code related to characters (and their representation), prosigns and phonetics to new file: libcw_data.c Having separate things in separate files (instead of having everything in a single 10kLOC file) should make some things easier for me as a maintainer of libcw. 2014-04-23 Kamil Ignacak * committing changes before a new release; the new release contains a fix of problem reported by Pino Zollo ZP4KFX. Se NEWS file for more details. 2013-12-08 Kamil Ignacak * cwgen: improving seed for random function. 2013-10-26 Kamil Ignacak * clocking of iambic keyer. There has been a problem with clocking iambic keyer when the state machine for the keyer was in motion. The clocking has been receiving imprecise timestamps, and so recognizing characters (e.g. in xcwcp's receiver) was difficult. Today I've committed code that fixes timing problems in clocking iambic keyer. The code updates receiver's timer with lengths of dequeued tones in cw_generator_dequeue_and_play_internal(). Receiver uses this updated timer as an argument to cw_{start|stop}_receive_tone(), and since the timer is updated with exact time values, the lengths of spaces and marks are more precise. Fixing the problem also required some changes in xcwcp/receiver.cc and xcwcp/application.cc. 2013-10-22 Kamil Ignacak * unit tests: adding first unit test in cwutils/dictionary module. 2013-10-19 Kamil Ignacak * unit tests: adding "tests::" and "testedin::" markings in functions' top level comments to indicate which functions are tested in which unit tests. Also rewriting parts of bodies of unit tests in libcwtest.c so that printout of test results is a bit cleaner. 2013-10-17 Kamil Ignacak * xcwcp: reviewing, commenting and reformatting code in receiver.cc - the file that uses libcw's receiver functionality. 2013-10-13 Kamil Ignacak * receiver code: more changes and reviewing of receiver code. Unit tests for two functions in recever section: cw_timestamp_validate_internal() and cw_timestamp_compare_internal(). I've reversed order of arguments for the first function, so the order now matches (output, input) pattern of parameters order. 2013-10-10 Kamil Ignacak * testing: some improvements in code testing receiving functions in libcwtest.c: simplifications, comments, refactoring. * refactoring in libcw.c: moving some free variables related to sending and receiving of Morse code into generator and receiver variables, respectively. 2013-10-06 Kamil Ignacak * tone queue: using "len" property to simplify management and monitoring of tone queue and its capacity. Code is now a bit simpler. 2013-10-05 Kamil Ignacak * tone queue: adding "len" property to tone queue. Adding and using it should simplify some aspects of queue management. 2013-10-04 Kamil Ignacak * tone queue: still working with capacity, head and tail. Updated data type for the three variables, it will be uint32_t. * debugging: introduced cw_assert() macro that should improve debugging and assertions. 2013-09-12 Kamil Ignacak * tone queue: more changes related to "capacity", and additionally "head" and "tail" properties of tone queue. No functionality changed yet, just some minor improvements, comments and tests. 2013-09-09 Kamil Ignacak * tone queue: refactoring code handling "capacity" of tone queue; two purposes: improved "testability" and possibility of assigning non-default capacities of tone queues. 2013-07-24 Kamil Ignacak * FreeBSD patches: applying patches for FreeBSD, provided by Diane Bruce (thank you!). Thanks to the patches the ./configure script now should support two new flags: --with-qt-includes= --with-qt-libraries= 2013-03-18 Kamil Ignacak * fixes: Thomas Beierlein has reported that some combinations of '--enable-*'/'--disable-*' flags result in a code that fails to compile. He also provided a patch that fixes it. I've created a tool ('unixcw/tools/test_configure_flags.sh') that tests all combinations of configure flags, which also detected one more faulty configuration, in addition to the ones discovered by Thomas. 2013-01-24 Kamil Ignacak * unit tests: src/libcw/libcwtests.c has been heavily refactored. The work on the file will continue to ensure that public API of libcw is tested as thoroughly as reasonably possible. * new functions: adding new functions: cw_character_is_valid() (replaces cw_check_character()) and cw_string_is_valid() (replaces cw_check_string()). The old functions are still available, but have been marked as deprecated. 2013-01-03 Kamil Ignacak * fixes: fixing a function in libcw that attempts to open audio device. Simple improvement of logic conditions makes it less possible (under certain circumstances) that the function will fail to open a device. * pre-release: new version of unicw will have version number 3.2.0. New version of libcw will have soname version 5.0.0. Implementing necessary changes related to the two pieces of information. Also attempting to build debian packages from unixcw source package, and fixing bugs and upgrading files in the process. Various other updates of files related to pre-release activities. 2012-12-31 Kamil Ignacak * distribution: src/libcw/libcw_debug.h is now marked as file to be installed along with libcw.h * generator: improved behaviour of cw_generator_new() in cases when the function failed to create a generator. Now if the function fails, the generator variable is fully 'de-initialized'. 2012-12-29 Kamil Ignacak * tone queue: improving the method of queuing a space character. This helps me avoid problems in some corner case (when a single space is queued, and tone queue's low watermark is set to 1). This problem has been spotted when testing cwdaemon. * compilation errors: unixcw/src/libcw/libcw.h: Rewriting three cases of usage of "__attribute__ ((deprecated(msg)))", some versions of gcc may not support "deprecated" with string argument (error reported by user). 2012-11-21 Kamil Ignacak * debugging: I have reviewed list of CW_DEBUG_* flags. Some of the names of the flags have changed. If you are using any of these flags, you need to review your code. debug module now provides updated macro printing debug messages. The macro now accepts 'severity level' flag (debug / info / warning / error). There are now three permanent debug objects provided by libcw. Two of them are only for debug purposes, the third one is for general use. Behaviour of the objects may be controlled by the severity flag, as well as by debug flags defining areas of code, for which the debugging is active. 2012-09-17 Kamil Ignacak * libcw: code implementing support for various audio backends has been moved from libcw.c to new files. That way we have less mess in libcw.c, better separation of modules, and cleaner space for improvements in code implementing support for audio backends (e.g. advanced API of PulseAudio). 2012-09-11 Kamil Ignacak * debug: adding src/libcw/libcw_debug.py - a tool that transforms timing information that may be printed by debugged libcw applications. The transformed timing information may be then plotted by plotting programs to gain insight into inner workings and time dependencies of different parts of libcw applications. The tool is rather imperfect and may need manual adjustments for every new situation, but hopefully it will turn out to be useful. * cwcp: refactoring cwcp.c, adding comments, fixing one small annoyance. 2012-08-15 Kamil Ignacak * tone slopes: libcw now can generate tones with slopes shaped as sine function or as raised cosine function. The 'raised cosine' slope is now default. Until now, shape of slopes has been calculated every time a tone has been generated. Now the shape is calculated only when some parameters of generator (volume, sample rate, length of slope) change. This should improve performance of libcw by one or two percents (no benchmarks were performed :/ ). 2012-08-11 Kamil Ignacak * debug: Adding src/libcw/libcw_debug.c module. Currently the module implements only debug events with time stamps, but most probably all debugging facilities will be moved to the module in future. 2012-08-06 Kamil Ignacak * build system configuration: fixing faulty logic checking "--disable-feature" flags in configure.ac. Bug reported by Thomas Beierlein. Thanks Thomas! 2012-07-04 Kamil Ignacak * libcw: fixing problem with interlocks in threaded code; since this is an important fix, I will have to prepare new release of unixcw. 2012-05-27 Kamil Ignacak * libcw: fixing an error with overflowing n_samples. It was spotted during some tests performed when reviewing files before new release. I guess that means that I'm in a phase of final tests of the package. * unixcw: bunch of changes that prepare the package for new release. New release number of unixcw will be 3.1.0, new soname of libcw will be 4:0:0. 2012-05-21 Kamil Ignacak * libcw: Implementing loading of PulseAudio and ALSA libraries at run-time (loading symbols from the two libraries - to be exact), instead of doing it at compile time (load time?). This means that support for PulseAudio and/or ALSA can be enabled during compile time, but user doesn't have to have PulseAudio and/or ALSA installed on target system in order to install libcw. In other words: PulseAudio and ALSA libraries are now recommended, but not required. This does not mean that the two libraries are somehow deprecated by libcw. It just means that installing libcw doesn't have to mean a necessity of installing too much additional packages. OSS - by its nature - doesn't have to be loaded to be used by libcw, it's just open(), write() and close(), so handling OSS is much easier and doesn't involve run time loading (the description is rather simplified, but still OSS is a different story than PulseAudio and ALSA libraries). 2012-05-17 Kamil Ignacak * libcw/pulseaudio: some general improvements in PulseAudio code; there may be a slight improvement in responsiveness, as I've added code that configures buffering attribute passed to pa_simple_new(). The configuration is very simple (read: code copied from the net), I suspect that it can be improved. * libcw/Null: Adding support for Null output. Null output is an empty device that doesn't produce a sound. It doesn't use any physical or logical device to output a sound. Its only function is to provide a timing information: it acts as if it accepts and plays x microseconds of sound, and it returns after the x microseconds. I'm not sure if this will turn out useful, maybe yes, maybe no. Currently it is implemented using single call to usleep(), without any checks of return value. This should be improved. Code from cwutils has been changed to use/provide functionality related to the new output. 2012-05-14 Kamil Ignacak * libcw/tone queue: cw_generator_write_sine_wave_internal(): using cw_signal_wait_internal() (together with pthread_kill() in enqueue function) instead of usleep() - this should decrease CPU usage in idle state; still needs to be tested and verified, but - overall - good idea; I think that this solution existed in libcw before I've started slaughtering the code, so consider this just rediscovering of a clever code; 2012-05-10 Kamil Ignacak * libcw/console: Console output now works correctly, playing nicely with queue()/dequeue() and the generator. 2012-05-06 Kamil Ignacak * cwcp/user interface: fixing small bug in code: till now modifying practice time didn't work correctly, any attempts to do so resulted in resetting the time to zero. Now this is fixed. 2012-05-01 Kamil Ignacak * libcw/experimental code: removed code that was disabled when CW_DEV_EXPERIMENTAL_WRITE was set to 1. 2012-05-01 Kamil Ignacak * libcw/audio: more changes in libcw; I'm decreasing dependency on timers, and increasing dependency on tone queue. I could put it that way: there are less places where time periods are dictated by itimers, and more places where time periods are measured by audio systems' 'write' functions. This way I am sure that when I'm sending X samples to audio sink, it - given sample rate Y - results in Z microseconds of sound. This seems like a good concept, it works well so far. I think that it will me impossible (and impractical) to get rid of all timers, but for generating audio - it works well. There may be a problem with console buzzer, as there is no audio sink that would accept X samples, but already I have an idea how to solve this. I've been using CW_DEV_EXPERIMENTAL_WRITE definition to enable new, experimental code, and disable old code. Since the new, experimental code works so well, I will completely get rid of the old code soon. 2012-04-25 Kamil Ignacak * libcw/ALSA: the problem described below has been solved, but at a cost of significant changes in how a Morse code sound is generated (timers are no longer used). This will almost certainly affect other parts of libcw (e.g. Morse keys handling), but it has advantages: timing of ALSA sound is (should be - to be tested) perfect, and I can easily add support for PulseAudio. (this change has been made and committed earlier, somewhere between 21.04 and 24.04, I'm just describing it now). * libcw/PulseAudio: Adding support for PulseAudio. PulseAudio only works with "experimental write" enabled, so there is no way that I can have both PulseAudio and old algorithm for generating audio. Either I will have to refactor/refresh/rework rest of libcw.c (and then have PulseAudio), or I will leave old way of generating audio (not breaking things (yet) in applications using libcw, but also not having PulseAudio). 2012-04-21 Kamil Ignacak * libcw/ALSA: I've noticed that there is a problem with waveform produced with ALSA. Dits and dashes start at correct time, but they are ended incorrectly - either too soon, or too late. This results in dots and dashes of incorrect length. The length differences are small, but audible. I have ruled out problems with itimer. itimer doesn't produce perfect time intervals, but error introduced by itimer is way to small to result in described problem. The problem is probably related to delay introduced by snd_pcm_writei(). I'm thinking about following solution: start generating tones (be it inter-symbol silence, or the symbols (dits and dashes) themselves) on signal generated by itimer, but stop generating dit/dash/silence after writing specific number of samples to audio device. In other words: start generating on timer events, stop generating on sample counter overflow. The problem doesn't seem to appear when using OSS output, perhaps because sound fragment size is much smaller than ALSA period size, e.g. 128 vs. 940. 2012-04-15 Kamil Ignacak * build system: Most important change: adding code that handles --disable-xxx options passed to the script: --disable-console --disable-oss --disable-alsa --disable-cwcp --disable-xcwcp The options allow disabling certain functionalities of unixcw, so that the package can be built on machines that don't provide some functions or properties. Example: unixcw 3.0.1 can't be compiled on hurd-i386 because of this error from configure script: "configure: error: Cannot find either sys/kd.h, sys/vtkd.h, or sys/kbio.h" At lease one of these headers is needed for console buzzer support. With new code in configure, compilation of code working with console buzzer can be disabled. Similarly, user can now disable compilation of OSS-related code on platforms that no longer provide OSS. Functionality can be disabled explicitly (with command line option), or implicitly - if any of tests performed by configure script fails. Changes described above required some modifications of libcw.c file. Also added --enable-dev. Build system now uses Makefile.am and Makefile.in files used/generated by Automake. Adding two calls to configure: AM_INIT_AUTOMAKE (build system now uses Automake to handle Makefile files), and AC_PROG_LIBTOOL (libtool is now used to create libraries). Build system now supports "make distcheck" target. Build system now depends on libtool. unixcw-3.5.0/icon_unixcw.svg0000644000175000017500000001426111663010242015723 0ustar acerionacerion image/svg+xml unixcw-3.5.0/icon_unixcw.xpm0000644000175000017500000235034311663010407015741 0ustar acerionacerion/* XPM */ static char * unixcw_xpm[] = { "800 800 3 1", " c None", ". c #FF0000", "+ c #000000", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ", " ...................................................................................................................................................... ......................................................................................................................................................

This is HISTORY file for unixcw. It describes major changes in unixcw releases. For detailed description of changes see NEWS file. The original UnixCW package, version 1, grew out of a desire to have a program available under Linux that was very similar to the one I was used to under DOS. While several Linux Morse Tutors were, in fact, still are, available, I never quite found one that did the stuff I wanted. From the original UnixCW package came version 2. This was almost a total rewrite, although it included the same basic binaries as were in version 1. The two major changes for this version were the addition of an extensive, general purpose CW library, and also an X Window-based CW tutor program. With version 2.1, finally, came full sound card support, built into the CW library itself. All three main user level programs that use the library were enhanced to allow control over the sound card tone volume. Console speaker sound is still there, if needed, but sound card tones became the default mode. Version 2.2 was a bug-fixed version of 2.1. It seems that some sound card drivers (some later OSS drivers) couldn't handle the volume control ioctls that the CW library uses, and this meant sound card tones would not work for these systems. To solve this, version 2.2 uses the /dev/mixer device to control volumes if it finds that it cannot do this with the main sound card device. Version 2.3 is a thorough overhaul, cleanup, and refactoring of version 2.2. All the code has been reformatted for correct Gnu style, and programs now take a lot more care over what they do, and don't do, in signal handler context. cwcp and xcwcp now offer fully configurable modes and dictionaries through a configuration file option, and xcwcp has been rewritten in proper C++ style. Version 3.0 has been prepared and released by new lead developer, Kamil Ignacak. The takeover of unixcw has been discussed with and approved by Simon Baldwin. Main changes in 3.0 are: o rewriting parts of libcw so that using OSS is less probable to cause problems (this should solve at least one Debian bug) o adding support for ALSA to libcw; libcw uses OSS as default audio system, but there are no differences in support of OSS and ALSA in terms of functionality o porting xcwcp to Qt4 The fact that there is a new maintainer should take some burden off of shoulders of Kamal Mostafa, who was responsible for (among other things) patching unixcw. Version 3.0 introduces some changes in API, and there should be some more API changes in 3.1. Hopefully things will be more stable in 3.2. Version 3.0.1 contains small fixes that don't influence core capabilities of any application, but are still important. Patches for this release were provided mainly by Kamal Mostafa (thanks Kamal!). Version 3.1.0 adds support for PulseAudio. Plenty of other changes in library code improve timings of tones produced by the library. Few library functions are deprecated, they are replaced by new functions. Version 3.1.1 fixes small problem with interlocks in thread code. Version 3.2.0 introduces small fixes and improvements in libcw, and implements new debug facilities (the old ones are being deprecated). It also fixes faulty logic checking "--disable-feature" flags in configure.ac. The problem was spotted by Thomas Beierlein. Version 3.3.0 is mostly fixes. More fixes in configuration flags (thanks again to Thomas Beierlein). Patches fixing compilation under FreeBSD (thanks to Diane Bruce). Fixes and improvements of handling of iambic keying in libcw and xcwcp. Fixing compilation error in cwutils/dictionary.h. Version 3.3.1 is just one fix in libcw. Thanks to Pino Zollo ZP4KFX for reporting a bug and testing solution. Version 3.4.0 contains two changes in source code: - refreshment of cwcp code; - splitting libcw.c into parts. Additionally the build system has been updated to correctly build unixcw on: - FreeBSD 10 (x86_64-unknown-freebsd10.0, with clang 3.3); - FreeBSD 9.3 (freebsd9.3 with gcc 4.2.1); - OpenBSD 5.5 (amd64-unknown-openbsd5.5 with gcc 4.2.1); Version 3.4.1 focused on internal changes in libcw. All library code is now split between separate module files. Some test code from libcw_test_public.c has been moved to respective modules. Version 3.4.2 focused on internal changes in libcw. Improving separation of modules in the library. Taking steps to separate library's global variables (generator, receiver, key) and functions implicitly operating on these variables from functions taking a generator, receiver, or key as an argument. Improving unit tests code. Testing unixcw on Alpine Linux (because of musl libc) and FreeBSD 10.0 (because this is *unix*cw). *** This file is no longer updated. *** *** See NEWS file for description of changes. ***unixcw-3.5.0/NEWS0000644000175000017500000005445512605000641013364 0ustar acerionacerionversion 3.5.0 / 2015-10-06 libcw: - adding few more small tests. - trying to fix a problem of short space. The problem occurs when client application has registered low-tone-queue callback, the threshold for the callback is set to 1, and a single end-of-word space has been enqueued by client application. When the eow space is enqueued as a single tone-queue tone (or even as two tones) ("short space"), older versions of libcw may miss the event of passing of tone queue level from 2 to 1 and will not call the callback. - Library soname/version changed from 6.4.1 to 6.5.1. xcwcp - porting the application from Qt4 to Qt5. ---------------------------------------------------------------------------- version 3.4.2 / 2015-06-17 libcw: - fixing one possible cause of segfaults in generator code (segfaults occurred when pthread_kill() was called with invalid thread ID in some specific circumstances). - fixing another problem with libcw: when a generator is created, then is *not* started, and then is deleted, libcw called pthread_kill(&id, ...) on uninitialized id in cw_gen_delete(). This caused a program to crash. - fixing problems with OSS and generator modules that surfaced during tests on Alpine Linux. - expanding unit tests. - libcw is now compiled with -DNDEBUG flag by default (asserts are "off"). The asserts are still "on" by default in "unit tests" libcw. Asserts are switched "on" in base libcw with "./configure --enable-dev". - cw_generator_set_tone_slope(): some corner cases of handling function's arguments were cleared in function's top level comments, and implementation has been updated accordingly. - Library soname/version changed from 6.3.1 to 6.4.1. ---------------------------------------------------------------------------- version 3.4.1 / 2015-01-02 libcw: - The remainder of code from libcw.c has been moved to respective module files. New module file has been created: libcw_rec.c - it contains receiver code. I think that number of modules won't change anymore. libcw.c has been removed, all functionality is now implemented by module files. - A number of unit test functions has been moved from libcw_test_public.c to respective module files. These functions can be executed independently, so there is no reason to keep them in libcw_test_public.c. They can be kept in module files, close to tested library functions. libcw_test_public.c is now less difficult to work with. The moved test functions are now executed while building "make check" target, so they should be called more often, increasing the chances of catching problems early. - Data sets for some of receiver's unit tests are now generated by helper functions. This allowed me to increase size of the data sets and increase variation of the data (both for fixed speed receiving and for adaptive receiving). The data sets are basically timing tables used to drive the receiver - to test main functions of the receiver, responsible for accepting mark/space events from client code. The increased size and variation of the test data gives me more confidence that the core functionality of the receiver works as expected. - If you run libcw in debugging mode and you depend on Receiver State names (strings starting with RS_) printed by library's debug messages, you may want to check changed values of RS enum and corresponding strings on top of libcw_rec.c - they have been changed. - Some changes have been made to library functions (mainly in generator and receiver modules) to ensure that the code separated between modules can be compiled and that it works as expected. Since receiver code has been put in a separate file, it was possible to review and refactor the receiver code a bit. No functionality of the library has been changed, with an exception described in next point. - Data type of receiver's speed is now internally a float instead of int. This change improves behaviour of adaptive receiving algorithm a bit. It's not a big change, but it may positively impact client code using receiver functions. - libcw_test_public test executable now accepts '-m' command line option (for selecting module(s)) to test. Check output of 'libcw_test_public -h' for more details. - Since the modification described above does not change how the library works, nor does it change any API, there is no reason for any major revision changes. Library soname/version has been changed from 6.2.1 to 6.3.1. ---------------------------------------------------------------------------- version 3.4.0 / 2014-11-11 unixcw: - Build system files have been modified to correctly configure and compile unixcw (or at least parts of it) on following platforms (in addition to Debian GNU/Linux): - FreeBSD 10.0 (x86_64-unknown-freebsd10.0, with clang 3.3); - FreeBSD 9.3 (freebsd9.3 with gcc 4.2.1); - OpenBSD 5.5 (amd64-unknown-openbsd5.5 with gcc 4.2.1); See INSTALL file for more information. - QT4 configuration flags (CFLAGS, LIBS, MOC) are now detected only by using pkg-config. My hand-made script that searched for QT4 files has been reduced to simple call to PKG_CHECK_MODULES(). This means that the following arguments are no longer accepted by configure script: --with-qt-cflags= --with-qt-libraries= If you want to override pkg-config settings, you can still use environment variables. Check output of "./configure --help" for details libcw: - Large parts of libcw.c have been moved to new files: - libcw_gen.c (generator) - libcw_tq.c (tone queue) - libcw_data.c (representations and lookup) - libcw_key.c (straight key, iambic keyer) - libcw_signal.c (signal handling) - libcw_utils.c (utility functions) Benefits of this move: - I won't have to use a table of contents to move around in libcw.c (the file had 10kLOC before this operation); - it will be easier to define boundaries between functionality of modules, and it will be easier to reason about how these modules should function and interact with each other; Check ChangeLog entry from 2014-07-28 for more information on this subject. Separation of libcw modules is not yet completed. Receiver code is still mixed with generator code, and there are still some functions left in libcw.c. I expect to finish the separation in one or two development cycles. - "make check" now builds three executables in libcw directory: - libcw_test_internal - libcw_test_public - libcw_test_simple_gen main() functions for test executables have been moved outside of libcw.c. - fixed bug in OSS code on BSD systems (found under FreeBSD 10). As part of configuring OSS device, libcw made this call: ioctl(*fd, SNDCTL_DSP_POST, ¶meter) It turns out that this call was unnecessary and returned error value. This prevented libcw from correctly opening OSS device. Now OSS device should be again available to unixcw applications. Notice that this bug most probably affected only BSD systems. - Library soname/version changed from 6.1.1 to 6.2.1. All these changes described above did not change API of the library in any way. Functionality of the library is intact. libcw.h header file has not been changed at all. cwcp: - cwcp ignored CWCP_OPTIONS environment variable. Now it should read it and use it as intended. - cwcp code has been reviewed. Code has been modified to ensure that each call to ncurses' newwin() is matched with delwin(). valgrind may still complain, but now the situation is a bit better. ---------------------------------------------------------------------------- version 3.3.1 / 2014-04-23 libcw: - Fixing bug discovered when fixing a problem with cwdaemon, reported by Pino Zollo ZP4KFX. Condition for calling "low water mark in tone queue" callback was invalid. This resulted in calling the callback too early or too often. - Library version changed from 6.0.1 to 6.1.1. Big *thank you* to Pino Zollo ZP4KFX for reporting a problem with cwdaemon and for helping to solve it in cwdaemon and in libcw. ---------------------------------------------------------------------------- version 3.3.0 / 2013.12.10 unixcw: - Thomas Beierlein has reported that some combinations of '--enable-*'/'--disable-*' flags result in a code that fails to compile. He also provided a patch that fixes it. I've created a tool ('unixcw/tools/test_configure_flags.sh') that tests all combinations of configure flags, which also detected one more faulty configuration, in addition to the ones discovered by Thomas. Thanks Thomas! - FreeBSD patches: Diane Bruce provided a set of patches that fix compilation on FreeBSD (thank you!). Thanks to the patches the ./configure script now should support two new flags: --with-qt-cflags= --with-qt-libraries= The state of build system on FreeBSD may still not be perfect (I didn't test this myself on FreeBSD), but should now be better than it was. libcw: - new functions: adding new functions: cw_character_is_valid() (replaces cw_check_character()) and cw_string_is_valid() (replaces cw_check_string()). The old functions are still available, but have been marked as deprecated. - unit tests: improvements and expansion of unit test code testing public API. - unit tests: improvements and expansion of unit test code testing libcw's internal functions. - receiver code (responsible for receiving and recognizing Morse code keyed with iambic keyer or straight key) has been reviewed. - code handling incoming events for receiving iambic keyer has been improved. iambic keyer events sent from client code to libcw are recognized with better precision, which leads to better recognition of keyed characters. These changes don't change public API nor "external" behaviour of libcw - these are just improvements of existing functionality. - new function: cw_iambic_keyer_register_timer(): to be used by client code that wants to receive Morse code sent with mouse or keyboard keys emulating iambic key. The function is related to the change mentioned one point above. At this point the interface to iambic keying becomes a bit more complicated. It will take me some more time to figure it out completely. For now I've made some internal fixes and changes that improve one aspect of this functionality, and as a result I had to add this one function. Expect more changes in future. If you want to see an example of usage of the keyer API, see xcwcp source code. xcwcp: - xcwcp takes advantage of changes in how libcw handles iambic keying, and - with some additional modifications in xcwcp's code - gets improved handling of iambic keying. cwgen: - improving randomness of generated strings; until now if cwgen was called twice within the same second, it produced the same result (since the random function has been seeded with value returned by time()). Now the seed comes from gettimeofday() (the milliseconds part), so randomness has been improved a bit. cwutils: - unit tests: adding first unit test in cwutils/dictionary module. - bugfix: usage of __attribute__ ((deprecated("message"))) construct in cwutils/dictionary.h may have lead to compilation failure. This has been fixed by getting rid of "message" argument. ---------------------------------------------------------------------------- version 3.2.0 / 2013.01.11 unixcw: - Fixing faulty logic checking "--disable-feature" flags in configure.ac. Bug reported by Thomas Beierlein. Thanks Thomas! libcw: - Debugging facilities of the library are being rewritten and have been moved to new file: src/lib/libcw_debug.h. See the file for details of new interface. The interface may still change, and it isn't documented yet. List of CW_DEBUG_* flags has been modified. The old interface is being deprecated. - libcw now can generate tones with slopes shaped as sine function or as raised cosine function. The 'raised cosine' slope is now default. - Rewriting usage of "__attribute__ ((deprecated(msg)))" facility in libcw.h. A user has reported errors related to the attribute when compiling libcw with gcc 4.3.3. - Improving the method of queuing a space character. This helps me avoid problems in some corner cases (e.g. when a single space is queued, and tone queue's low watermark is set to 1). - Improving behaviour of cw_generator_new(). Under some circumstances it is less likely to fail to create new generator. There was also possibility of causing a client application to crash if the function failed, but this has been fixed. - Library version changed from 4.1.1 to 5.0.0. cwcp: - Fixing one small issue: in every new session with cwcp the application printed a space at the beginning of played text. ---------------------------------------------------------------------------- version 3.1.1 / 2012.07.04 libcw: - Fixing problem with interlocks in thread code. Library version changed from 4.0.0 to 4.1.1. ---------------------------------------------------------------------------- version 3.1.0 / 2012.06.30 unixcw: - Added support for PulseAudio. All applications from unixcw that produce audio output benefit from this. PulseAudio is the default audio backend on machines with installed and accessible PulseAudio server. If audio backend hasn't been specified by user, the applications try to access different sound backends in following order: PulseAudio -> OSS -> ALSA -> console buzzer. The usual restrictions for console buzzer output (root privileges required) still apply. Running application from unixcw package (cw, cwcp, xcwcp) with ALSA selected as sound backend while PulseAudio server is running will result in all kinds of different problems. User is warned about such situation by the application. - Added 'Null' audio system as an optional audio backend. No sound is being played if this system is selected, libcw is spending its time only on generating tones of proper length and sending then in proper moments to a pseudo-device. Pass '-s n' option to unixcw application to use this 'audio' backend. - Thanks to changes in libcw, unixcw doesn't 'require' ALSA or PulseAudio libraries, or PulseAudio server on target system, even if support for the two audio backends was compiled in. The two audio backends are now only recommended, thanks to linking to the libraries at run time. - Build system now uses libtool. 'libtool' script is in release archive, so there are no new compile-time requirements related to this (at least 'make distcheck' completes successfully with libtool package uninstalled). - It is possible to explicitly disable support for audio backends at compile time. Pass --disable-{console|oss|alsa|pulseaudio} to ./configure to do this. - It is possible to explicitly disable compilation of cwcp and xcwcp. Pass --disable-{cwcp|xcwcp} to ./configure to do this. - Build system now uses Makefile.am files as a basis to generate Makefile files. - Build system now supports and correctly builds "make distcheck" target. libcw: - Added support for PulseAudio. There are still some things to be improved in code implementing support for PulseAudio, but pretty solid basics are there. - Added support for Null pseudo-audio-system. Not sure if it will be useful, I just thought that someone would like to use libcw without generating any sound. Perhaps some simple platforms without audio devices, perhaps practicing sending/keying without playback. Who knows. It was easy to do, so I did it. - If you compare libcw.c files from this and previous release, you will notice lots of changes. This is because I've changed the algorithm that controls time periods when generating tones (generating sine wave). Until now the periods were measured with itimers. The tricky part was to keep two processed in sync: turning sine wave on and off, and sending the content of audio buffer with sine wave to audio backend. I'm calling it 'tricky' because it works fine only for small sizes of audio buffer, as was is in case of OSS (~128 samples). With larger buffer sizes forced by ALSA (~1k samples) the two processes de-synchronize. I had to come up with better design, and the side effect of the design is total rewrite of parts of libcw.c (for my own purposes I call the rewrite a 'butchering', but that is a different story). New design relies on blocking writes to audio systems, and their property of being able to play only X samples (Y milliseconds) at a time (with given sample rate). - Following functions are deprecated: cw_check_representation(), cw_lookup_representation(), cw_lookup_character(). Use these instead: cw_representation_is_valid(), cw_representation_to_character(), cw_character_to_representation(). - library's soname changed from 3.0.1 to 4.0.0 Library's version becomes independent from version of unixcw. cwcp: - Fixing small bug in user interface: till now modifying practice time didn't work correctly, any attempts to do so resulted in resetting the time to zero. Now this is fixed. ---------------------------------------------------------------------------- version 3.0.2 / 2012.06.18 New version. You won't find it in git repo, but only in SourceForge download area and on Debian webpage. This is a special release with two goals related to Debian packaging: debian/: - fixing Debian's FTBFS bug #676752 - removing debian/ from unixcw_X.Y.Z.orig.tar.gz. Contents of debian/ can be found in separately provided unixcw_X.Y.Z-W.debian.tar.gz Thanks to Kamal Mostafa for patiently explaining to me some details of Debian/Ubuntu packaging. ---------------------------------------------------------------------------- version 3.0.1 / 2012.01.08 Thanks to Kamal Mostafa for providing patches that are the reason for 3.0.1 release. Content of upstream package unixcw-3.0.1 is approximately the same as of Debian source package unixcw_3.0-5. debian/: - added proper "Section" field in control file; - fixed library dependencies in control file; - fixed "Replaces:"/"Conflicts:" fields in control file; - fixed Debian bug #653411: changes in *.preinst files to remove dangling symlinks left by old packaging (suggested by Bob Proulx); general: - fixed library dependencies in "configure" script; - fixed library dependencies provided by libcw.pc file; libcw: - proper detection of capabilities of liboss-salsa-dev (kfreebsd's libasound implementation); libcw now can be built properly on Debian/kFreeBSD; - fixing awk scripts producing man pages: the awk scripts now work with mawk too; cwcp: - fixed list of libraries in Makefile; ---------------------------------------------------------------------------- version 3.0 / 2011.12.13 Thanks to Simon Baldwin for creating this software in the first place, and to Kamal Mostafa for helping me with packaging unixcw 3.0 for Debian. unixcw: - Changed major version of unixcw package to '3'. Changes listed below probably justify this. - New main developer: Kamil Ignacak - New website: http://unixcw.sourceforge.net - Scripts building Debian packages now build 'libcw3' package instead of 'unixcw' package, and 'libcw3-dev' Debian package instead of 'unixcw-dev' Debian package. libcw: - Renamed 'cwlib' part of unixcw package to 'libcw'. - Renamed library's header file from cwlib.h to libcw.h. - Changed library's soname from 0 to 3 (/usr/lib/libcw.so.3.0.0 / libcw.so.3). - Added support for ALSA. OSS is still the default backend. - As a consequence, libasound2 is a new dependency. There is no possibility (yet) to disable or reconfigure this at build time. It is possible to select sound backend in applications that use libcw. - Added implicit dependency on pthread library (which is a part of libc library, so it should be available on target system by default). Main routine generating sine wave operates as a separate thread. - Added actual slopes to dot and dash sounds produced by the library. This should result in less of (or even none) audible pops. Unfortunately current implementation makes dots and dashes a tiny bit longer than they would be without the slopes. The difference is not significant, but I plan to re-implement it in the future to make this feature 100% correct. The slopes are linear. - Rewritten management of sound volume so that the library doesn't use OSS mixer. This should resolve Debian bug #567394 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=567394). Code that controls volume level is common for OSS and ALSA. - Since libcw doesn't touch the mixer device anymore, then Debian bug #567392 should be resolved as well (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=567392). - Added code that attempts to discover proper audio buffer size for both OSS and ALSA. This should resolve Debian bug #567395 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=567395). - Fix of Debian bug #567395 should also solve Debian bug #567397 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=567397). - Changed library's API. There will be more API changes in 3.1, so consider current API to be unstable. - Changed volume change step from 5% to 1%. - Changed frequency change step from 100Hz to 20Hz. - The library no longer can produce sound on console buzzer and on sound card at the same time. - The library knows default names of OSS, ALSA and console buzzer devices. The names are used to open sound devices if no other names are provided explicitly as function arguments. - Introduced symbolic names of int values returned by most of library's function: CW_FAILURE / CW_SUCCESS. xcwcp: - Ported xcwcp to QT4. This should resolve Debian bug #604386 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=604386). - Added auto-detection of QT4 headers and QT4 moc by build files. unixcw-3.5.0/THANKS0000644000175000017500000000272212373716241013602 0ustar acerionacerionunixcw was developed by Simon Baldwin, G0FRD . ---------- Thanks to... Kamal Mostafa, KA6MAL, for reviewing the libcw API, showing me the errors of my ways with 64-bit integers, and hounding me to add the adaptive receive speed tracking... Joop Stakenborg, PG4I, for being a willing "guinea pig" with various snapshots of unfinished versions of the package, for help in isolating various sound card problems, and for his continued enthusiasm and interest in maintaining UnixCW as a Debian Linux package... Paolo Cravero, IK1ZYW, for very kindly making the first sound card patch available for UnixCW 2. His tone generation code is now fully embedded inside the CW library, and it's no exaggeration to say that without his help, there would still be no sound card support in UnixCW... Michael D. Ivey, for identifying a problem with CW sending rhythm when sending in 'Farnsworth' mode, and for taking the time and trouble to test the patches I sent him... Wolf-Ruediger Juergens, for ideas on implementing CW weighting... Diane Bruce and Jason L. Wright, for adding support for assorted BSD flavors... Dan Jacobson, for making improvement suggestions above and beyond the call of duty... And finally, everyone else who has sent feedback about UnixCW. If not for your interest, and fairly frequent requests for a version that works with a sound card, the package would not have progressed at all.
