To use normal completion and ignore these key completions, type a space. * Edit current line in external editor: ctrl-x (#161) Fixes: * Python 2.5 compatibility, thanks to Michael Schuller (#279). Python 2.5 is not officially supported, but after few changes Michael introduced, he says it's working fine. * FakeStream has flush(), so works correctly with django.core.email.backends.console thanks to Marc Sibson (#259) * FakeStdin has fileno() (#232) * Changes to sys.ps1 and sys.ps2 are respected thanks to Michael Schulle (#267) * atexit registered functions run on exit (#258) * fixed an error on exit code when running a script with bpython script.py (#260) * setup.py extras are used to define dependencies for urwid and curtsies frontends There's a new frontend for bpython: bpython-curtsies. Curtsies is a terminal wrapper written to making native scrolling work in bpython. (#56, #245) Try bpython-curtsies for the bpython experience with a vanilla python layout. (demo: http://ballingt.com/assets/bpython-curtsies-scroll-demo-large.gif) This curtsies frontend addresses some issues unfixed in bpython-cli, and has a few extra features: * Editing full interpreter history in external editor with F7, which is rerun as in rewind * A new interpreter is used for rewind, unless bpython-curtsies was started with custom locals or in interactive mode (#71) * Ctrl-c behaves more like vanilla python (#177) * Completion still works if cursor at the end of the line (#147) * Movement keys meta-b, meta-f, and meta-backspace, ctrl-left and ctrl-right are all honored (#246, #201) * Non-ascii characters work in the file save prompt (#236) * New --type / -t option to run the contents of a file as though they were typed into the bpython-curtsies prompt A few things about bpython-curtsies are worse than regular bpython: * Bad things can happen when using several threads (#265) * output prints slowly (#262) * bpython-curtsies can't be backgrounded and resumed correctly (via ctrl-z, fg) (#274) There are two new options in the new [curtsies] section of the bpython config * list_above: whether completion window can cover text above the current line; defaults to True * fill_terminal: whether bpython-curtsies should be fullscreen (like bpython); defaults to False 0.12 ---- We want to give special thanks to the Hacker School project- (https://www.hackerschool.com/) for choosing bpython as their pet hacking project. In special we would like to thank the following people for contributing their code to bpython: - Martha Girdler - Allison Kaptur - Ingrid Cheung We'd also like to thank Eike Hein for contributing his pastebin code which now makes it possible to paste using a 3rd party program unlocking a whole slew of pastebins for bpython users. * Added a new pastebin_helper config option to name an executable that should perform pastebin upload on bpython's behalf. If set, this overrides pastebin_url. Data is supplied to the helper via STDIN, and it is expected to return a pastebin URL as the first word of its output. * Fixed a bug causing pastebin upload to fail after a previous attempt was unsuccessful. A duplicate pastebin error would be displayed in this case, despite the original upload having failed. * Added more key shortcuts to bpython.urwid * Smarter dedenting after certain expressions * #74 fixed broken completion when auto_display_list was disabled We also have done numerous cleanup actions including building the man pages from our documentation. Including the documentation in the source directory. Some minor changes to the README to have EOL 79 and changes to urwid to work better without twisted installed. * Fix ungetch issues with Python 3.3. See issues #230, #231. 0.11 ---- A bugfix/cleanup release .The fixed bugs are: * #204: "import math" not autocompleting on python 3.2 Otherwise lots of small additions to the to be replacement for our ncurses frontend, the urwid frontend. I'd like to specifically thank Amjith Ramanujam for his work on history search which was further implemented and is in working order right now. 0.10.1 ------ A bugfix release. The fixed bugs are: * #197: find_modules crashes on non-readable directories * #198: Source tarball lacks .po files 0.10 ---- As a highlight of the release, Michele Orrù added i18n support to bpython. Some issues have been resolved as well: * Config files are now located according to the XDG Base Directory Specification. The support for the old bpythonrc files has been dropped and ~/.bpython.ini as config file location is no longer supported. See issue #91. * Fixed some issues with tuple unpacking in argspec. See issues #133 and #138. * Fixed a crash with non-ascii filenames in import completion. See issue #139. * Fixed a crash caused by inspect.findsource() raising an IndexError which happens in some situations. See issue #94. * Non-ascii input should work now under Python 3. * Issue #165: C-a and C-e do the right thing now in urwid. * The short command-line option "-c config" was dropped as it conflicts with vanilla Python's "-c command" option. See issue #186. 0.9.7.1 ------- A bugfix release. The fixed bugs are: * #128: bpython-gtk is broken * #134: crash when using pastebin and no active internet connection 0.9.7 ----- Well guys. It's been some time since the latest release, six months have passed We have added a whole slew of new features, and closed a number of bugs as well. We also have a new frontend for bpython. Marien Zwart contributed a urwid frontend as an alternative for the curses frontend. Be aware that there still is a lot to fix for this urwid frontend (a lot of the keyboard shortcuts do not yet work for example) but please give it a good spin. Urwid also optionally integrates with a Twisted reactor and through that with things like the GTK event loop. At the same time we have done a lot of work on the GTK frontend. The GTK frontend is now 'usable'. Please give that a spin as well by running bpython-gtk on you system. We also welcome a new contributor in the name of Michele Orrù who we hope will help us fix even more bugs and improve functionality. As always, please submit any bugs you might find to our bugtracker. * Pastebin confirmation added; we were getting a lot of people accidentally pastebinning sensitive information so I think this is a good idea. * Don't read PYTHONSTARTUP when executed with -i. * BPDB was merged in. BPDB is an extension to PDB which allows you to press B in a PDB session which will let you be dropped into a bpython sessions with the current PDB locals(). For usage, see the documentation. * The clear word shortcut (default: C-w) now deletes to the buffer. * More tests have been added to bpython. * The pastebin now checks for a previous paste (during the session) with the exact same content to guard against twitchy fingers pastebinning multiple times. * Let import completion return "import " instead of "import". * GTK now has pastebin, both for full log as well as the current selection. * GTK now has write2file. * GTK now has a menu. * GTK now has a statusbar. * GTK now has show source functionality. * GTK saves the pastebin url to the clipboard. * GTK now has it's own configuration section. * Set focus to the GTK text widget to allow for easier embedding in PIDA and others which fixes issues #121. * #87: Add a closed attribute to Repl to fix mercurial.ui.ui expecting stderr to have this attribute. * #108: Unicode characters in docstring crash bpython * #118: Load_theme is not defined. * #99: Configurable font now documented. * #123: Pastebin can't handle 'ESC' key * #124: Unwanted input when using / keys in the statusbar prompt. 0.9.6.2 ------- Unfortunately another bugfix release as I (Bob) broke py3 support. * #84: bpython doesn't work with Python 3 Thanks very much to Henry Prêcheur for both the bug report and the patch. 0.9.6.1 ------- A quick bugfix release (this should not become a habit). * #82: Crash on saving file. 0.9.6 ------ A bugfix/feature release (and a start at gtk). Happy Christmas everyone! * #67: Make pastebin URL really configurable. * #68: Set a__main__ module and set interpreter's namespace to that module. * #70: Implement backward completion on backward tab. * #62: Hide matches starting with a _ unless explicitly typed. * #72: Auto dedentation * #78: Theme without a certain value raises exception - add the possibility for a banner to be shown on bpython startup (when embedded or in code) written by Caio Romao. - add a hack to add a write() method to our fake stdin object - Don't use curses interface when stdout is not attached to a terminal. - PEP-8 conformance. - Only restore indentation when inside a block. - Do not decrease the lineno in tracebacks for Py3 - Do not add internal code to history. - Make paren highlighting more accurate. - Catch SyntaxError in import completion. - Remove globals for configuration. - rl_history now stays the same, also after undo. 0.9.5.2 ------- A bugfix release. Fixed issues: * #60: Filename expansion: Cycling completions and deleting * #61: Filename expansion: Directory names with '.'s get mangled Other fixes without opened issues: * Encode items in the suggestion list properly * Expand usernames in file completion correctly * future imports in startup scripts can influence interpreter's behaviour now * Show the correct docstring for types without a own __init__ method 0.9.5.1 -------- Added missing data files to the tarball. 0.9.5 ----- Fixed issues: * #25 Problems with DEL, Backspace and C-u over multiple lines * #49 Sending last output to $PAGER * #51 Ability to embed bpython shell into an existing script * #52 FakeStdin.readlines() is broken * #53 Error on printing null character * #54 Parsing/introspection ncurses viewer neglects parenthesis bpython has added a view source shortcut to show the source of the current function. The history file is now really configurable. This issue was reported in Debian's bugtracker. bpython has now some basic support for Python 3 (requires Pygments >=1.1.1). As a result, setuptools is now optional. The pastebin URL is now configurable and the default pastebin is now bpaste.net Argument names are now shown as completion suggestions and one can tab through the completion list. 0.9.4 ----- Bugfix release (mostly) * when typing a float literal bpython autocompletes int methods (#36) * Autocompletion for file names (#40) * Indenting doesn't reset (#27) * bpython configuration has moved from ~/.bpython.ini to ~/.bpython/config (currently still supporting fallback) * leftovers of statusbar when exiting bpython cleaned up * bpython now does not crash when a 'popup' goes out of window bounds * numerous fixes and improvements to parentheses highlighting * made *all* keys configurable (except for arrow keys/pgup/pgdown) 0.9.3 ------ This release was a true whopper! * Full unicode support * Configurable hotkey support * Theming support * Pastemode, disables syntax highlighting during a paste for faster pasting, highlights when done * Parentheses matching * Argument highlighting 0.9.2 ----- * help() now uses an external pager if available. * Fix for highlighting prefixed strings. * Fix to reset string highlighting after a SyntaxError. * bpython now uses optparse for option parsing and it supports --version now. * Configuration files are no longer passed by the first command line argument but by the -c command line switch. * Fix for problem related to editing lines in the history: http://bitbucket.org/bobf/bpython/issue/10/odd-behaviour-when-editing-commands-in-the-history 0.9.1 ----- * Fixed a small but annoying bug with sys.argv ini file passing * Fix for Python 2.6 to monkeypatch they way it detects callables in rlcompleter * Config file conversion fix 0.9.0 ----- * Module import completion added. * Changed to paste.pocoo.org due to rafb.net no longer offering a pastebin service. * Switched to .ini file format for config file. * White background-friendly colour scheme added. * C-l now clears the screen. * SyntaxError now correctly added to history to prevent it garbling up on a redraw. Probably some other things, but I hate changelogs. :) 0.8.0 ------ It's been a long while since the last release and there have been numerous little bugfixes and extras here and there so I'm putting this out as 0.8.0. Check the hg commit history if you want more info: http://bitbucket.org/bobf/bpython/ 0.7.2 ----- Menno sent me some patches to fix some stuff: * Socket error handled when submitting to a pastebin. * Resizing could crash if you resize small enough. Other stuff: * 'self' in arg list is now highlighted a different colour. * flush_output option added to config to control whether output is flushed to stdout or not on exit. * Piping something to bpython made it lock up as stdin was not the keyboard - bpython just executes stdin and exits instead of trying to do something clever. * Mark Florisson (eggy) gave me a patch that stops weird breakage when unicode objects get added into the output buffer - they now get encoded into the output encoding. * Bohdan Vlasyuk sent me a patch that fixes a problem with the above patch from Mark if sys.__stdout__.encoding didn't exist. * Save to file now outputs executable code (i.e. without the >>> and ... and with "# OUT: " prepended to all output lines). I never used this feature much but someone asked for this behaviour. 0.7.1 ----- * Added support for a history file, defaults to ~/.pythonhist and 100 lines but is configurable from the rc file (see sample-rc). * Charles Duffy has added a yank/put thing - C-k and C-y. He also ran the code through some PEP-8 checker thing and fixed up a few old habits I manage to break but didn't manage to fix the code to reflect this - thank you! * Jørgen Tjernø has fixed up the autoindentation issues we encountered when bringing soft tabs in. * SyntaxError, ValueError and OverflowError are now caught properly (code.InteractiveInterpreter treats these as different to other exceptions as it doesn't print the whole traceback, so a different handler is called). This was discovered as I was trying to stop autoindentation from occurring on a SyntaxError, which has also been fixed. * '.' now in sys.path on startup. 0.7.0 ----- C-d behaviour changed so it no longer exits if the current line isn't empty. Extra linebreak added to end of stdout flush. pygments and pyparsing are now dependencies. Jørgen Tjernø has done lots of cool things like write a manpage and .desktop file and improved the way tabbing works and also added home, end and del key handling as well as C-w for deleting words - thanks a lot! raw_input() and all its friends now work fine. PYTHONSTARTUP handled without blowing up on stupid errors (it now parses the file at once instead of feeding it to the repl line-by-line). 0.6.4 ----- KeyboardInterrupt handler clears the list window properly now. 0.6.3 ----- Forgot to switch rpartition to split for 2.4 compat. 0.6.2 ----- The help() now works (as far as I can see) exactly the same as the vanilla help() in the regular interpreter. I copied some code from pydoc.py to make it handle the special cases, e.g. help('keywords') help('modules') etc. 0.6.1 ----- Somehow it escaped my attention that the list window was never fully using the rightmost column, except for the first row. This is because me and numbers don't have the best relationship. I think stability is really improving with the latest spat of bugfixes, keep me informed of any bugs. 0.6.0 ----- No noticeable changes except that bpython should now work with Python 2.4. Personally I think it's silly to make a development tool work with an out of date version of Python but some people seem to disagree. The only real downside is that I had to do a horrible version of all() using reduce(), otherwise there's no real differences in the code. 0.5.3 ----- Now you can configure a ~/.bpythonrc file (or pass a rc file at the command line (bpython /foo/bar). See README for details. 0.5.2 ----- help() actually displays the full help page, and I fixed up the ghetto pager a little. 0.5.1 ----- Now you can hit tab to display the autocomplete list, rather than have it pop up automatically as you type which, apparently, annoys Brendogg. 0.5.0 ----- A few people have commented that the help() built-in function doesn't work so well with bpython, since Python will try to output the help string to PAGER (usually "less") which obviously makes everything go wrong when curses is involved. With a bit of hackery I've written my own ghetto pager and injected my own help function into the interpreter when it initialises in an attempt to rectify this. As such, it's pretty untested but it seems to be working okay for me. Suggestions/bug reports/patches are welcome regarding this. 0.4.2 ----- Well, hopefully we're one step closer to making the list sizing stuff work. I really hate doing code for that kind of thing as I never get it quite right, but with perseverence it should end up being completely stable; it's not the hardest thing in the world. Various cosmetic fixes have been put in at the request of a bunch of people who were kind enough to send me emails regarding their experiences. PYTHONSTARTUP is now dealt with and used properly, as per the vanilla interpreter. 0.4.1 ----- It looks like the last release was actually pretty bug-free, aside from one tiny bug that NEVER ACTUALLY HAPPENS but someone was bugging me about it anyway, oh well. 0.4.0 ----- It's been quite a long time since the last update, due to several uninteresting and invalid excuses, but I finally reworked the list drawing procedures so the crashing seems to have been taken care of to an extent. If it still crashes, the way I've written it will hopefully allow a much more robust way of fixing it, one that might actually work. 0.3.2 ----- Thanks to Aaron Gallagher for pointing out a case where the hugely inefficient list generation routines were actually making a significant issue; they're much more efficient now and should hopefully not cause any more problems. 0.3.1 ----- Thanks to Klaus Alexander Seis for the expanduser() patch. Auto indent works on multiple levels now. 0.3.0 ----- Now with auto-indent. Let me know if it's annoying. 0.2.4 ----- Thanks a lot to Angus Gibson for submitting a patch to fix a problem I was having with initialising the keyboard stuff in curses properly. Also a big thanks to John Beisley for providing the patch that shows a class __init__ method's argspec on class instantiation. I've fixed up the argspec display so it handles really long argspecs (e.g. subprocess.Popen()) and doesn't crash if something horrible happens (rather, it avoids letting something horrible happen). I decided to add a key that will get rid of the autocomplete window, since it can get in the way. C-l seemed like a good choice, since it would work well as a side-effect of redrawing the screen (at least that makes sense to me). In so doing I also cleaned up a lot of the reevaluating and resizing code so that a lot of the strange output seen on Rewind/resize seems to be gone. 0.2.3 ----- The fix for the last bug broke the positioning of the autocomplete box, whoops. 0.2.2 ----- That pesky bug keeps coming up. I think it's finally nailed but it's just a matter of testing and hoping. I hate numbers. 0.2.1 ----- I'm having a bit of trouble with some integer division that's causing trouble when a certain set of circumstances arise, and I think I've taken care of that little bug, since it's a real pain in the ass and only creeps up when I'm actually doing something useful, so I'll test it for a bit and release it as hopefully a bug fixed version. 0.2.0 ----- A little late in the day to start a changelog, but here goes... This version fixed another annoying little bug that was causing crashes given certain exact circumstances. I always find it's the way with curses and sizing of windows and things... I've also got bpython to try looking into pydoc if no matches are found for the argspec, which means the builtins have argspecs too now, hooray. bpython-0.16/doc/sphinx/source/bpdb.rst0000644000175100017510000000061612776765047020152 0ustar useruser00000000000000.. _bpdb: bpdb ==== To enable bpython support within pdb, start pdb with the following code: .. code-block:: python import bpdb bpdb.set_trace() This will drop you into bpdb instead of pdb, which works exactly like pdb except that you can additionally start bpython at the current stack frame by issuing the command `Bpython` or `B`.

If you want to find out more about the bpython interpreter you can visit our website: http://bpython-interpreter.org Contents: .. toctree:: :maxdepth: 2 authors contributing configuration themes releases community django windows changelog bpaste tips bpdb bpython-0.16/doc/sphinx/source/themes.rst0000644000175100017510000000330312776765047020524 0ustar useruser00000000000000.. _themes: Themes ====== This chapter is about bpython's theming capabilities. bpython uses .theme files placed in your ``$XDG_CONFIG_HOME/bpython`` directory [#f1]_. You can set the theme in the :ref:`configuration_color_scheme` option in your ``$XDG_CONFIG_HOME/bpython/config`` file (:ref:`configuration`). Available Colors ---------------- * k = black * r = red * g = green * y = yellow * b = blue * m = magenta * c = cyan * w = white * d = default, this will make the switch default to the bpython default theme Any letter writing uppercase will make the switch bold. Available Switches ------------------ * keyword * name * comment * string * error * number * operator * punctuation * token * background * output * main * prompt * prompt_more * right_arrow_suggestion Default Theme ------------- The default theme included in bpython is as follows: .. code-block:: python :linenos: # Each letter represents a colour marker: # k, r, g, y, b, m, c, w, d # which stands for: # blacK, Red, Green, Yellow, Blue, Magenta, Cyan, White, Default # Capital letters represent bold # Copy to $XDG_CONFIG_HOME/bpython/foo.theme and set "color_scheme = foo" in # $XDG_CONFIG_HOME/bpython/config ($XDG_CONFIG_HOME defaults to ~/.config) [syntax] keyword = y name = c comment = b string = m error = r number = G operator = Y punctuation = y token = C paren = R [interface] # XXX: gnome-terminal appears to be braindead. The cursor will disappear unless # you set the background colour to "d". background = k output = w main = c prompt = c prompt_more = g right_arrow_suggestion = K .. :: Footnotes .. [#f1] ``$XDG_CONFIG_HOME`` defaults to ``~/.config`` if not set. bpython-0.16/doc/sphinx/source/bpaste.rst0000644000175100017510000000050112776765047020512 0ustar useruser00000000000000.. _bpaste: bpaste ====== bpaste (http://bpaste.net) is the pastebin which we run for bpython. bpython is configured by default to paste to this pastebin. Removal ------- If you want a paste removed from the pastebin you can use the removal link as shown by bpython. Refer to https://bpaste.net/removal if you lost it. bpython-0.16/doc/sphinx/source/tips.rst0000644000175100017510000000147612776765047020227 0ustar useruser00000000000000.. _tips: Tips and tricks =============== There are various tricks and tips to bpython. We currently list one of them on this page. If you know any more, don't hesitate to let us know (:ref:`community`)! bpython and multiple python versions ------------------------------------ To use bpython with multiple version items this trick has been relayed to us by Simon Liedtke. Do a source checkout of bpython and add the following to your `.profile` equivalent file. .. code-block:: bash alias bpython3.5='PYTHONPATH=~/python/bpython python3.5 -m bpython.cli' Where the `~/python/bpython`-path is the path to where your bpython source code resides. You can of course add multiple aliases, so you can run bpython with 2.7 and the 3 series. .. note:: Make sure you have the dependencies installed on all Python versions. bpython-0.16/doc/sphinx/source/configuration.rst0000644000175100017510000000061212776765047022106 0ustar useruser00000000000000.. _configuration: Configuration ============= You can edit the config file by pressing F3 (default). If a config file does not exist you will asked if you would like to create a file. By default it will be saved to ``$XDG_CONFIG_HOME/.config/bpython/config`` [#f1]_. .. include:: configuration-options.rst .. :: Footnotes .. [#f1] ``$XDG_CONFIG_HOME`` defaults to ``~/.config`` if not set. bpython-0.16/doc/sphinx/source/django.rst0000644000175100017510000000414412776765047020505 0ustar useruser00000000000000.. _django: Django / Pinax ============== Django is a web framework for professionals with deadlines. People like to interactively talk to their Django models. Currently Django comes with two hardcoded options. Either you use the standard Python REPL, or you use IPython. Pinax is an integrated collection of Django applications, a sort of Django with out of the box models and views for a lot of stuff. For those people wanting to use bpython with their Django installation you can follow the following steps. Written by Chanita Siridechkun. The following instructions make bpython try to import a setting module in the current folder and let django set up its enviroment with the settings module (if found) if bpython can't find the settings module nothing happens and no enviroment gets set up. The addition also checks if settings contains a PINAX_ROOT (if you use Pinax), if it finds this key it will do some additional Pinax setup. The Pinax addition was written by Skylar Saveland. bpython uses something called the PYTHONSTARTUP enviroment variable. This is also used by the vanilla Python REPL. Add the following lines to your ``.profile`` or equivalent file on your operating system (``.bash_profile`` on Mac OS X if you use the default shell): .. code-block:: text export PYTHONSTARTUP=~/.pythonrc This sets the environment variable PYTHONSTARTUP to the contents of the ``~/.pythonrc`` file when you log in. To this ``~/.pythonrc`` file you add the following lines: .. code-block:: python try: from django.core.management import setup_environ import settings setup_environ(settings) if settings.PINAX_ROOT: import sys from os.path import join sys.path.insert(0, join(settings.PINAX_ROOT, "apps")) sys.path.insert(0, join(settings.PROJECT_ROOT, "apps")) except: pass And add an empty line at the end. You need one or it will raise an error. Login again, or execute the ``source ~/.profile`` equivalent for your shell and you should be set to go if you run bpython in a django folder (where the settings.py resides). bpython-0.16/doc/sphinx/source/man-bpython.rst0000644000175100017510000000736112776765047021503 0ustar useruser00000000000000:orphan: bpython manual page =================== Synopsis -------- **bpython** [*options*] [*file* [*args*]] **bpython-curses** [*options*] [*file* [*args*]] **bpython-urwid** [*options*] [*file* [*args*]] Description ----------- The idea is to provide the user with all the features in-line, much like modern IDEs, but in a simple, lightweight package that can be run in a terminal window. In-line syntax highlighting. Hilights commands as you type! Readline-like autocomplete with suggestions displayed as you type. Press tab to complete expressions when there's only one suggestion. Expected parameter list. This displays a list of parameters for any function you call. It uses the inspect module, then tries pydoc. Rewind. This is a bit misleading, but it code that has been entered is remembered, and when you Rewind, it pops the last line and re\-evaluates the entire code. This is error\-prone, and mostly useful for defining classes and functions. Pastebin code/write to file. This posts the current buffer to a pastebin (bpaste.net) or writes it to a file. Flush curses screen to stdout. Unlike other curses apps, bpython dumps the screen data to stdout when you quit, so you see what you've done in the buffer of your terminal. Options ------- The long and short forms of options, shown here as alternatives, are equivalent. If :program:`bpython` sees an argument it does not know, execution falls back to the regular Python interpreter. The following options are supported by all frontends: --config= Use instead of default config file. -h, --help Show the help message and exit. -i, --interactive Drop to bpython shell after running file instead of exiting. The PYTHONSTARTUP file is not read. -q, --quiet Do not flush the output to stdout. -V, --version Print :program:`bpython`'s version and exit. In addition to the above options, :program:`bpython` also supports the following options: -L, --log Write debugging messages to the file bpython.log. Use -LL for more verbose logging. -p file, --paste=file Paste in the contents of a file at startup. In addition to the common options, :program:`bpython-urwid` also supports the following options if Twisted is available: -r , --reactor= Use Twisted's instead of urwid's event loop. --help-reactors Display a list of available Twisted reactors. -p , --plugin= Execute a :program:`twistd` plugin. Use :program:`twistd` to get a list of available plugins. Use -- to pass options to the plugin. -s , --server= Run an eval server on port . This option forces the use of a Twisted reactor. Keys ---- :program:`bpython`'s keys are fully configurable. See http://docs.bpython-interpreter.org/configuration.html#keyboard Files ----- **$XDG_CONFIG_HOME/bpython/config** Your bpython config. See sample-config (in /usr/share/doc/bpython/examples on Debian) for various options you can use, or read :manpage:`bpython-config(5)`. Known bugs ---------- See http://github.com/bpython/bpython/issues/ for a list of known issues. See also -------- :manpage:`bpython-config(5)`, :manpage:`python(1)` Author ------ :program:`bpython` was written by Robert Anthony Farrell and his bunch of loyal followers. This manual page was written by Jørgen Pedersen Tjernø , for the Debian project (but may be used by others). bpython-0.16/doc/sphinx/source/windows.rst0000644000175100017510000000111612776765047020731 0ustar useruser00000000000000.. _windows: Windows ======= When bpython was developed it only supported Linux and we grew support for other platforms as well. There are no official binaries for bpython on Windows (though this is something we plan on providing in the future). The easiest way to get `bpython.cli` (the curses frontend running) is to install an unofficial windows binary for pdcurses from: http://www.lfd.uci.edu/~gohlke/pythonlibs/#curses. After this you can just `pip install bpython` and run bpython curses frontend like you would on a Linux system (e.g. by typing `bpython-curses` on your prompt). bpython-0.16/doc/sphinx/source/configuration-options.rst0000644000175100017510000002271112776765047023603 0ustar useruser00000000000000General ------- This refers to the ``[general]`` section in your `$XDG_CONFIG_HOME/bpython/config` file. arg_spec ^^^^^^^^ Display the arg spec (list of arguments) for callables, when possible (default: True). auto_display_list ^^^^^^^^^^^^^^^^^ Display the autocomplete list as you type (default: True). When this is off, you can hit tab to see the suggestions. autocomplete_mode ^^^^^^^^^^^^^^^^^ There are three modes for autocomplete. simple, substring, and fuzzy. Simple matches methods with a common prefix, substring matches methods with a common subsequence, and fuzzy matches methods with common characters (default: simple). As of version 0.14 this option has no effect, but is reserved for later use. .. versionadded:: 0.12 .. _configuration_color_scheme: color_scheme ^^^^^^^^^^^^ See :ref:`themes` for more information. Color schemes should be put in ``$XDG_CONFIG_HOME/bpython/``. For example, to use the theme ``$XDG_CONFIG_HOME/bpython/foo.theme`` set ``color_scheme = foo`` Leave blank or set to "default" to use the default (builtin) theme. complete_magic_methods ^^^^^^^^^^^^^^^^^^^^^^ Whether magic methods should be auto completed (default: True). dedent_after ^^^^^^^^^^^^ Number of blank lines required before next line will be dedented (default: 1). If set to 0, automatic dedenting never occurs. editor ^^^^^^ Editor for externally editing the current line, session, or config file. .. versionadded:: 0.13 flush_output ^^^^^^^^^^^^ Whether to flush all output to stdout on exit (default: True). Only relevant to bpython-curses and bpython-urwid. highlight_show_source ^^^^^^^^^^^^^^^^^^^^^ Whether the source code of an object should be syntax highlighted (default: True). hist_duplicates ^^^^^^^^^^^^^^^ Whether to store duplicate entries in the history (default: True). hist_file ^^^^^^^^^ History file (default: ``~/.pythonhist``). hist_length ^^^^^^^^^^^ Number of lines to store in history (set to 0 to disable) (default: 100). paste_time ^^^^^^^^^^ The time between keypresses before pastemode is deactivated in bpython-curses (default: 0.02). pastebin_confirm ^^^^^^^^^^^^^^^^ Whether pasting to a pastebin needs to be confirmed before sending the data (default: True). pastebin_expiry ^^^^^^^^^^^^^^^ Time duration after which a paste should expire. Valid values are ``1day``, ``1week`` and ``1month`` (default: ``1week``). .. versionadded:: 0.14 pastebin_helper ^^^^^^^^^^^^^^^ The name of a helper executable that should perform pastebin upload on bpython's behalf. If set, this overrides `pastebin_url`. It also overrides `pastebin_show_url`, as the helper is expected to return the full URL to the pastebin as the first word of its output. The data is supplied to the helper via STDIN. An example helper program is ``pastebinit``, available for most systems. The following helper program can be used to create `gists `_: .. code-block:: python #!/usr/bin/env python import sys import urllib2 import json def do_gist_json(s): """ Use json to post to github. """ gist_public = False gist_url = 'https://api.github.com/gists' data = {'description': None, 'public': None, 'files' : { 'sample': { 'content': None } }} data['description'] = 'Gist from BPython' data['public'] = gist_public data['files']['sample']['content'] = s req = urllib2.Request(gist_url, json.dumps(data), {'Content-Type': 'application/json'}) try: res = urllib2.urlopen(req) except HTTPError, e: return e try: json_res = json.loads(res.read()) return json_res['html_url'] except HTTPError, e: return e if __name__ == "__main__": s = sys.stdin.read() print do_gist_json(s) .. versionadded:: 0.12 pastebin_show_url ^^^^^^^^^^^^^^^^^ The url under which the new paste can be reached. ``$paste_id`` will be replaced by the ID of the new paste (default: https://bpaste.net/show/$paste_id/). pastebin_removal_url ^^^^^^^^^^^^^^^^^^^^ The url under which a paste can be removed. ``$removal_id`` will be replaced by the removal ID of the paste (default: https://bpaste.net/remova/$removal_id/). .. versionadded:: 0.14 pastebin_url ^^^^^^^^^^^^ The pastebin url to post to (without a trailing slash). This pastebin has to be a pastebin which uses provides a similar interface to ``bpaste.net``'s JSON interface (default: https://bpaste.net/json/new). save_append_py ^^^^^^^^^^^^^^ Whether to append ``.py`` to the filename while saving the input to a file. .. versionadded:: 0.13 single_undo_time ^^^^^^^^^^^^^^^^ Time duration an undo must be predicted to take before prompting to undo multiple lines at once. Use -1 to never prompt, or 0 to always prompt. (default: 1.0) .. versionadded:: 0.14 syntax ^^^^^^ Syntax highlighting as you type (default: True). tab_length ^^^^^^^^^^ Soft tab size (default 4, see PEP-8). unicode_box ^^^^^^^^^^^ Whether to use Unicode characters to draw boxes. .. versionadded:: 0.14 Keyboard -------- This section refers to the ``[keyboard]`` section in your ``$XDG_CONFIG_HOME/bpython/config``. You can set various keyboard shortcuts to be used by bpython. However, we have yet to map all keys to their respective control codes. If you configure a key combination which is not yet supported by bpython it will raise an exception telling you the key does not exist in bpython.keys. Valid keys are: * Control + any alphanumeric character (C-a through C-z, also a few others). * Any function key ranging from F1 to F12. backspace ^^^^^^^^^ Default: C-h Delete character in front of the cursor. .. versionadded:: 0.14 beginning_of_line ^^^^^^^^^^^^^^^^^ Default: C-a Move to the beginning of the line. .. versionadded:: 0.14 clear_line ^^^^^^^^^^ Default: C-u Clears to the beginning of the line. clear_screen ^^^^^^^^^^^^ Default: C-l Clears the screen to the top. clear_word ^^^^^^^^^^ Default: C-w Clear the word the cursor is currently on. copy_clipboard ^^^^^^^^^^^^^^ Default: F10 Copy the entire session to clipboard. .. versionadded:: 0.14 cut_to_buffer ^^^^^^^^^^^^^ Default: C-k Cuts the current line to the buffer. delete ^^^^^^ Default: C-d Delete character under the cursor. down_one_line ^^^^^^^^^^^^^ Default: C-n Move the cursor down, by one line. edit_config ^^^^^^^^^^^ Default: F3 Edit bpython configuration in external editor. .. versionadded:: 0.14 edit_current_block ^^^^^^^^^^^^^^^^^^ Default: C-x Edit current block in external editor. .. versionadded:: 0.14 end_of_line ^^^^^^^^^^^ Default: C-e Move to the of the line. .. versionadded:: 0.14 exit ^^^^ Default: C-d Exits bpython (use on empty line) external_editor ^^^^^^^^^^^^^^^ Default: F7 Edit the entire session in an external editor. .. versionadded:: 0.13 help ^^^^ Default: F1 Brings up sincerely cheerful description of bpython features and current key bindings. .. versionadded:: 0.14 incremental_search ^^^^^^^^^^^^^^^^^^^^^^^^^^ Default: M-s Perform incremental search on all stored lines in the history. .. versionadded:: 0.15 last_output ^^^^^^^^^^^ Default: F9 Shows the last output in the systems $PAGER. Only works in bpython-curses. left ^^^^ Default: C-b Move a character to the left. .. versionadded:: 0.14 pastebin ^^^^^^^^ Default: F8 reimport ^^^^^^^^ Default: F6 Reruns entire session, reloading all modules by clearing the sys.modules cache. .. versionadded:: 0.14 reverse_incremental_search ^^^^^^^^^^^^^^^^^^^^^^^^^^ Default: M-r Perform reverse incremental search on all stored lines in the history. .. versionadded:: 0.15 right ^^^^^ Default: C-f Move a character to the right. .. versionadded:: 0.14 save ^^^^ Default: C-s Saves the current session to a file (prompts for filename) search ^^^^^^ Default: C-o Search up for any lines containing what is on the current line. show_source ^^^^^^^^^^^ Default: F2 Shows the source of the currently being completed (python) function. toggle_file_watch ^^^^^^^^^^^^^^^^^ Default: F5 Toggles file watching behaviour; re-runs entire bpython session whenever an imported module is modified. .. versionadded:: 0.14 transpose_chars ^^^^^^^^^^^^^^^ Default: C-t Transpose current character with the one left of it. .. versionadded:: 0.14 undo ^^^^ Default: C-r Rewinds the last action. up_one_line ^^^^^^^^^^^ Default: C-p Move the cursor up, by one line. yank_from_buffer ^^^^^^^^^^^^^^^^ Default: C-y Pastes the current line from the buffer (the one you previously cutted) CLI --- This refers to the ``[cli]`` section in your config file. suggestion_width ^^^^^^^^^^^^^^^^ Default: 0.8 The width of the suggestion window in percent of the terminal width. .. versionadded:: 0.9.8 trim_prompts ^^^^^^^^^^^^ Default: False Trims lines starting with '>>> ' when set to True. curtsies -------- This refers to the ``[curtsies]`` section in your config file. .. versionadded:: 0.13 list_above ^^^^^^^^^^ Default: False When there is space above the current line, whether the suggestions list will be displayed there instead of below the current line. right_arrow_completion ^^^^^^^^^^^^^^^^^^^^^^ Default: True Full line suggestion and completion (like fish shell and many web browsers). Full line completions are displayed under the cursor in gray. When the cursor is at the end of a line, pressing right arrow or ctrl-f will complete the full line. This option also turns on substring history search, highlighting the matching section in previous result.

Getting your development environment set up ------------------------------------------- bpython supports Python 2.7, 3.3 and newer. The code is compatible with all supported versions without the need to run post processing like `2to3`. Using a virtual environment is probably a good idea. Create a virtual environment with .. code-block:: bash # determines Python version used $ virtualenv bpython-dev # necessary every time you work on bpython $ source bpython-dev/bin/activate Fork bpython in the GitHub web interface, then clone the repo: .. code-block:: bash $ git clone git@github.com:YOUR_GITHUB_USERNAME/bpython.git # or "git clone https://github.com/YOUR_GITHUB_USERNAME/bpython.git" Next install the install your development copy of bpython and its dependencies: .. code-block:: bash $ cd bpython # install bpython and required dependencies $ pip install -e . # install optional dependencies $ pip install watchdog urwid # development dependencies $ pip install sphinx mock nose # this runs your modified copy of bpython! $ bpython .. note:: Many requirements are also available from your distribution's package manager. On Debian/Ubuntu based systems, the following packages can be used: .. code-block:: bash $ sudp apt-get install python-greenlet python-pygments python-requests $ sudo apt-get install python-watchdog python-urwid $ sudo apt-get install python-sphinx python-mock python-nose Remember to replace ``python`` with ``python3`` in every package name if you intend to develop with Python 3. You also need to run `virtualenv` with `--system-site-packages` packages, if you want to use the packages provided by your distribution. .. note:: Installation of some dependencies with ``pip`` requires Python headers and a C compiler. These are also available from your package manager. .. code-block:: bash $ sudo apt-get install gcc python-dev As a first dev task, I recommend getting `bpython` to print your name every time you hit a specific key. To run tests from the bpython directory: .. code-block:: bash $ nosetests If you want to skip test cases that are known to be slow, run `nosetests` in the following way: .. code-block:: bash $ nosetests -A "speed != 'slow'" Building the documentation -------------------------- The documentation is included in the bpython repository. After checking out the bpython repository and installing `sphinx` as described in the previous step, you can run the following command in your checkout of the repository to build the documentation: .. code-block:: bash $ make -C doc/sphinx html Afterwards you can point your browser to `doc/sphinx/build/html/index.html`. Don't forget to recreate the HTML after you make changes. Hacking on the site or theme ---------------------------- The site (and its theme as well) is stored in a separate repository and built using pelican. To start hacking on the site you need to start out with a checkout and probably a virtual environment: .. code-block:: bash $ virtualenv bpython-site-dev $ source bpython-site-dev/bin/activate $ pip install pelican Fork bsite and bsite-theme in the GitHub web interface, then clone the repositories: .. code-block:: bash $ git clone git@github.com:YOUR_GITHUB_USERNAME/bsite.git $ git clone git@github.com:YOUR_GITHUB_USERNAME/bsite-theme.git Next you can fiddle around in the source files. If you want to build the site you activate your virtualenv and tell pelican to generate the site with the included configuration file. .. code-block:: bash $ source bpython-site-dev/bin/activate # if you want to fiddle on the text of the site otherwise go into # bsite-theme $ cd bsite # if you checked out the theme in a different place, use that path $ pelican -t ../bsite-theme -s pelicanconf.py After this you can open the `output/index.html` in your favourite browser and see if your changes had an effect. .. _GitHub issue tracker: https://github.com/bpython/bpython/issues .. _bite-size: https://github.com/bpython/bpython/labels/bitesize bpython-0.16/doc/sphinx/source/community.rst0000644000175100017510000000174112776765047021267 0ustar useruser00000000000000.. _community: Community ========= Do you need help with using bpython? Do you want to thank the contributors personally? Or maybe you want to help out, contribute some code or resources or want to help in making bpython known to other persons? These are the places where you can find us. IRC --- You can find us in `#bpython `_ on the `Freenode `_ network. Don't worry when you get no response (this does not usually happen) but we are all from Europe and when you get to the channel during our nighttime you might have to wait a while for a response. Mailing List ------------ We have a mailing list at `google groups `_. You can post questions there and releases are announced on the mailing list.

bpython is a fancy interface to the Python interpreter. It has the following features:

  • In-line syntax highlighting.
  • Readline-like autocomplete with suggestion displayed as you type.
  • Expected parameter list for any Python function.
  • "Rewind" function to pop the last line of code from memory and re-evaluate.
  • Send the code you've entered off to a pastebin.
  • Save the code you've entered to a file.
  • Auto-indentation.

These features include **syntax highlighting**, **expected parameter list**, **auto-indentation**, and **autocompletion**. (See below for example usage). .. image:: http://i.imgur.com/jf8mCtP.gif :alt: bpython :width: 646 :height: 300 :align: center bpython does **not** aim to be a complete IDE - the focus is on implementing a few ideas in a practical, useful, and lightweight manner. bpython is a great replacement to any occasion where you would normally use the vanilla Python interpreter - testing out solutions to people's problems on IRC, quickly testing a method of doing something without creating a temporary file, etc.. You can find more about bpython - including `full documentation`_ - at our `homepage`_. .. contents:: :local: :depth: 1 :backlinks: none ========================== Installation & Basic Usage ========================== If you have `pip`_ installed, you can simply run: .. code-block:: bash $ pip install bpython Start bpython by typing ``bpython`` in your terminal. You can exit bpython by using the ``exit()`` command or by pressing control-D like regular interactive Python. =================== Features & Examples =================== * Readline-like autocomplete, with suggestions displayed as you type. * In-line syntax highlighting. This uses Pygments for lexing the code as you type, and colours appropriately. * Expected parameter list. As in a lot of modern IDEs, bpython will attempt to display a list of parameters for any function you call. The inspect module is tried first, which works with any Python function, and then pydoc if that fails. * Rewind. This isn't called "Undo" because it would be misleading, but "Rewind" is probably as bad. The idea is that the code entered is kept in memory and when the Rewind function is called, the last line is popped and the entire session is re-evaluated. Use to rewind. * Edit the current line or your entire session in an editor. F7 opens the current session in a text editor, and if modifications are made, the session is rerun with these changes. * Pastebin code/write to file. Use the key to upload the screen's contents to pastebin, with a URL returned. * Reload imported Python modules. Use to clear sys.modules and rerun your session to test changes to code in a module you're working on. ============= Configuration ============= See the sample-config file for a list of available options. You should save your config file as **~/.config/bpython/config** (i.e. ``$XDG_CONFIG_HOME/bpython/config``) or specify at the command line:: bpython --config /path/to/bpython/config ============ Dependencies ============ * Pygments * requests * curtsies >= 0.1.18 * greenlet * six >= 1.5 * Sphinx != 1.1.2 (optional, for the documentation) * mock (optional, for the testsuite) * babel (optional, for internationalization) * watchdog (optional, for monitoring imported modules for changes) * jedi (optional, for experimental multiline completion) Python 2 before 2.7.7 --------------------- If you are using Python 2 before 2.7.7, the following dependency is also required: * requests[security] cffi ---- If you have problems installing cffi, which is needed by OpenSSL, please take a look at `cffi docs`_. bpython-urwid ------------- ``bpython-urwid`` requires the following additional packages: * urwid ========== Known Bugs ========== For known bugs please see bpython's `known issues and FAQ`_ page. ====================== Contact & Contributing ====================== I hope you find it useful and please feel free to submit any bugs/patches suggestions to `Robert`_ or place them on the GitHub `issues tracker`_. For any other ways of communicating with bpython users and devs you can find us at the community page on the `project homepage`_, or in the `community`_. Hope to see you there! =================== CLI Windows Support =================== Dependencies ------------ `Curses`_ Use the appropriate version compiled by Christoph Gohlke. `pyreadline`_ Use the version in the cheeseshop. Recommended ----------- Obtain the less program from GnuUtils. This makes the pager work as intended. It can be obtained from cygwin or GnuWin32 or msys Current version is tested with ------------------------------ * Curses 2.2 * pyreadline 1.7 Curses Notes ------------ The curses used has a bug where the colours are displayed incorrectly: * red is swapped with blue * cyan is swapped with yellow To correct this I have provided a windows.theme file. This curses implementation has 16 colors (dark and light versions of the colours) ============ Alternatives ============ `ptpython`_ `IPython`_ Feel free to get in touch if you know of any other alternatives that people may be interested to try. .. _ptpython: https://github.com/jonathanslenders/ptpython .. _ipython: https://ipython.org/ .. _homepage: http://www.bpython-interpreter.org ..

The only way I have been able to think of is to keep the code that's been typed in in memory and re-evaluate it in its entirety for each "undo" operation. Obviously this means some operations could be extremely slow. I'm not even by any means certain that this truly represents a genuine "undo" implementation, but it does seem to be generally pretty effective.
