Please see our [FAQ](https://github.com/wycats/handlebars.js/blob/master/FAQ.md) for common issues that people run into. Should you run into other issues with the project, please don't hesitate to let us know by filing an [issue][issue]! In general we are going to ask for an example of the problem failing, which can be as simple as a jsfiddle/jsbin/etc. We've put together a jsfiddle [template][jsfiddle] to ease this. (We will keep this link up to date as new releases occur, so feel free to check back here) Pull requests containing only failing thats demonstrating the issue are welcomed and this also helps ensure that your issue won't regress in the future once it's fixed. Documentation issues on the handlebarsjs.com site should be reported on [handlebars-site](https://github.com/wycats/handlebars-site). ## Pull Requests We also accept [pull requests][pull-request]! Generally we like to see pull requests that - Maintain the existing code style - Are focused on a single change (i.e. avoid large refactoring or style adjustments in untouched code if not the primary goal of the pull request) - Have [good commit messages](http://tbaggery.com/2008/04/19/a-note-about-git-commit-messages.html) - Have tests - Don't significantly decrease the current code coverage (see coverage/lcov-report/index.html) ## Building To build Handlebars.js you'll need a few things installed. * Node.js * [Grunt](http://gruntjs.com/getting-started) Before building, you need to make sure that the Git submodule `spec/mustache` is included (i.e. the directory `spec/mustache` should not be empty). To include it, if using Git version 1.6.5 or newer, use `git clone --recursive` rather than `git clone`. Or, if you already cloned without `--recursive`, use `git submodule update --init`. Project dependencies may be installed via `npm install`. To build Handlebars.js from scratch, you'll want to run `grunt` in the root of the project. That will build Handlebars and output the results to the dist/ folder. To re-run tests, run `grunt test` or `npm test`. You can also run our set of benchmarks with `grunt bench`. The `grunt dev` implements watching for tests and allows for in browser testing at `http://localhost:9999/spec/`. If you notice any problems, please report them to the GitHub issue tracker at [http://github.com/wycats/handlebars.js/issues](http://github.com/wycats/handlebars.js/issues). ## Ember testing The current ember distribution should be tested as part of the handlebars release process. This requires building the `handlebars-source` gem locally and then executing the ember test script. ```sh npm link grunt build release cp dist/*.js $emberRepoDir/bower_components/handlebars/ cd $emberRepoDir npm link handlebars npm test ``` ## Releasing Handlebars utilizes the [release yeoman generator][generator-release] to perform most release tasks. A full release may be completed with the following: ``` yo release npm publish yo release:publish components handlebars.js dist/components/ cd dist/components/ gem build handlebars-source.gemspec gem push handlebars-source-*.gem ``` After this point the handlebars site needs to be updated to point to the new version numbers. The jsfiddle link should be updated to point to the most recent distribution for all instances in our documentation.

How can I file a bug report: See our guidelines on [reporting issues](https://github.com/wycats/handlebars.js/blob/master/CONTRIBUTING.md#reporting-issues). 1. Why isn't my Mustache template working? Handlebars deviates from Mustache slightly on a few behaviors. These variations are documented in our [readme](https://github.com/wycats/handlebars.js#differences-between-handlebarsjs-and-mustache). 1. Why is it slower when compiling? The Handlebars compiler must parse the template and construct a JavaScript program which can then be run. Under some environments such as older mobile devices this can have a performance impact which can be avoided by precompiling. Generally it's recommended that precompilation and the runtime library be used on all clients. 1. Why doesn't this work with Content Security Policy restrictions? When not using the precompiler, Handlebars generates a dynamic function for each template which can cause issues with pages that have enabled Content Policy. It's recommended that templates are precompiled or the `unsafe-eval` policy is enabled for sites that must generate dynamic templates at runtime. 1. How can I include script tags in my template? If loading the template via an inlined ` ``` It's generally recommended that templates are served through external, precompiled, files, which do not suffer from this issue. 1. Why are my precompiled scripts throwing exceptions? When using the precompiler, it's important that a supporting version of the Handlebars runtime be loaded on the target page. In version 1.x there were rudimentary checks to compare the version but these did not always work. This is fixed under 2.x but the version checking does not work between these two versions. If you see unexpected errors such as `undefined is not a function` or similar, please verify that the same version is being used for both the precompiler and the client. This can be checked via: ```sh handlebars --version ``` If using the integrated precompiler and ```javascript console.log(Handlebars.VERSION); ``` On the client side. We include the built client libraries in the npm package for those who want to be certain that they are using the same client libraries as the compiler. Should these match, please file an issue with us, per our [issue filing guidelines](https://github.com/wycats/handlebars.js/blob/master/CONTRIBUTING.md#reporting-issues). 1. Why doesn't IE like the `default` name in the AMD module? Some browsers such as particular versions of IE treat `default` as a reserved word in JavaScript source files. To safely use this you need to reference this via the `Handlebars['default']` lookup method. This is an unfortunate side effect of the shims necessary to backport the Handlebars ES6 code to all current browsers. 1. How do I load the runtime library when using AMD? There are two options for loading under AMD environments. The first is to use the `handlebars.runtime.amd.js` file. This may require a [path mapping](https://github.com/wycats/handlebars.js/blob/master/spec/amd-runtime.html#L31) as well as access via the `default` field. The other option is to load the `handlebars.runtime.js` UMD build, which might not require path configuration and exposes the library as both the module root and the `default` field for compatibility. If not using ES6 transpilers or accessing submodules in the build the former option should be sufficient for most use cases. handlebars.js-4.0.5/Gruntfile.js000066400000000000000000000147161262352515600165530ustar00rootroot00000000000000/* eslint-disable no-process-env */ module.exports = function(grunt) { grunt.initConfig({ pkg: grunt.file.readJSON('package.json'), eslint: { options: { }, files: [ '*.js', 'bench/**/*.js', 'tasks/**/*.js', 'lib/**/!(*.min|parser).js', 'spec/**/!(*.amd|json2|require).js' ] }, clean: ['tmp', 'dist', 'lib/handlebars/compiler/parser.js'], copy: { dist: { options: { processContent: function(content) { return grunt.template.process('/*!\n\n <%= pkg.name %> v<%= pkg.version %>\n\n<%= grunt.file.read("LICENSE") %>\n@license\n*/\n') + content; } }, files: [ {expand: true, cwd: 'dist/', src: ['*.js'], dest: 'dist/'} ] }, cdnjs: { files: [ {expand: true, cwd: 'dist/', src: ['*.js'], dest: 'dist/cdnjs'} ] }, components: { files: [ {expand: true, cwd: 'components/', src: ['**'], dest: 'dist/components'}, {expand: true, cwd: 'dist/', src: ['*.js'], dest: 'dist/components'} ] } }, babel: { options: { sourceMaps: 'inline', loose: ['es6.modules'], auxiliaryCommentBefore: 'istanbul ignore next' }, amd: { options: { modules: 'amd' }, files: [{ expand: true, cwd: 'lib/', src: '**/!(index).js', dest: 'dist/amd/' }] }, cjs: { options: { modules: 'common' }, files: [{ cwd: 'lib/', expand: true, src: '**/!(index).js', dest: 'dist/cjs/' }] } }, webpack: { options: { context: __dirname, module: { loaders: [ // the optional 'runtime' transformer tells babel to require the runtime instead of inlining it. { test: /\.jsx?$/, exclude: /node_modules/, loader: 'babel-loader?optional=runtime&loose=es6.modules&auxiliaryCommentBefore=istanbul%20ignore%20next' } ] }, output: { path: 'dist/', library: 'Handlebars', libraryTarget: 'umd' } }, handlebars: { entry: './lib/handlebars.js', output: { filename: 'handlebars.js' } }, runtime: { entry: './lib/handlebars.runtime.js', output: { filename: 'handlebars.runtime.js' } } }, requirejs: { options: { optimize: 'none', baseUrl: 'dist/amd/' }, dist: { options: { name: 'handlebars', out: 'dist/handlebars.amd.js' } }, runtime: { options: { name: 'handlebars.runtime', out: 'dist/handlebars.runtime.amd.js' } } }, uglify: { options: { mangle: true, compress: true, preserveComments: /(?:^!|@(?:license|preserve|cc_on))/ }, dist: { files: [{ cwd: 'dist/', expand: true, src: ['handlebars*.js', '!*.min.js'], dest: 'dist/', rename: function(dest, src) { return dest + src.replace(/\.js$/, '.min.js'); } }] } }, concat: { tests: { src: ['spec/!(require).js'], dest: 'tmp/tests.js' } }, connect: { server: { options: { base: '.', hostname: '*', port: 9999 } } }, 'saucelabs-mocha': { all: { options: { build: process.env.TRAVIS_JOB_ID, urls: ['http://localhost:9999/spec/?headless=true', 'http://localhost:9999/spec/amd.html?headless=true'], detailedError: true, concurrency: 4, browsers: [ {browserName: 'chrome'}, {browserName: 'firefox', platform: 'Linux'}, {browserName: 'safari', version: 7, platform: 'OS X 10.9'}, {browserName: 'safari', version: 6, platform: 'OS X 10.8'}, {browserName: 'internet explorer', version: 11, platform: 'Windows 8.1'}, {browserName: 'internet explorer', version: 10, platform: 'Windows 8'}, {browserName: 'internet explorer', version: 9, platform: 'Windows 7'} ] } }, sanity: { options: { build: process.env.TRAVIS_JOB_ID, urls: ['http://localhost:9999/spec/umd.html?headless=true', 'http://localhost:9999/spec/amd-runtime.html?headless=true', 'http://localhost:9999/spec/umd-runtime.html?headless=true'], detailedError: true, concurrency: 2, browsers: [ {browserName: 'chrome'} ] } } }, watch: { scripts: { options: { atBegin: true }, files: ['src/*', 'lib/**/*.js', 'spec/**/*.js'], tasks: ['build', 'amd', 'tests', 'test'] } } }); // Build a new version of the library this.registerTask('build', 'Builds a distributable version of the current project', [ 'eslint', 'parser', 'node', 'globals']); this.registerTask('amd', ['babel:amd', 'requirejs']); this.registerTask('node', ['babel:cjs']); this.registerTask('globals', ['webpack']); this.registerTask('tests', ['concat:tests']); this.registerTask('release', 'Build final packages', ['eslint', 'amd', 'uglify', 'test:min', 'copy:dist', 'copy:components', 'copy:cdnjs']); // Load tasks from npm grunt.loadNpmTasks('grunt-contrib-clean'); grunt.loadNpmTasks('grunt-contrib-concat'); grunt.loadNpmTasks('grunt-contrib-connect'); grunt.loadNpmTasks('grunt-contrib-copy'); grunt.loadNpmTasks('grunt-contrib-requirejs'); grunt.loadNpmTasks('grunt-contrib-uglify'); grunt.loadNpmTasks('grunt-contrib-watch'); grunt.loadNpmTasks('grunt-babel'); grunt.loadNpmTasks('grunt-eslint'); grunt.loadNpmTasks('grunt-saucelabs'); grunt.loadNpmTasks('grunt-webpack'); grunt.task.loadTasks('tasks'); grunt.registerTask('bench', ['metrics']); grunt.registerTask('sauce', process.env.SAUCE_USERNAME ?

Handlebars.js and Mustache are both logicless templating languages that keep the view and the code separated like we all know they should be. Checkout the official Handlebars docs site at [http://www.handlebarsjs.com](http://www.handlebarsjs.com) and the live demo at [http://tryhandlebarsjs.com/](http://tryhandlebarsjs.com/). Installing ---------- See our [installation documentation](http://handlebarsjs.com/installation.html). Usage ----- In general, the syntax of Handlebars.js templates is a superset of Mustache templates. For basic syntax, check out the [Mustache manpage](http://mustache.github.com/mustache.5.html). Once you have a template, use the `Handlebars.compile` method to compile the template into a function. The generated function takes a context argument, which will be used to render the template. ```js var source = "

Hello, my name is {{name}}. I am from {{hometown}}. I have " + "{{kids.length}} kids:

" + ""; var template = Handlebars.compile(source); var data = { "name": "Alan", "hometown": "Somewhere, TX", "kids": [{"name": "Jimmy", "age": "12"}, {"name": "Sally", "age": "4"}]}; var result = template(data); // Would render: //

Hello, my name is Alan. I am from Somewhere, TX. I have 2 kids:

Precompiling Templates ---------------------- Handlebars allows templates to be precompiled and included as javascript code rather than the handlebars template allowing for faster startup time. Full details are located [here](http://handlebarsjs.com/precompilation.html). Differences Between Handlebars.js and Mustache ---------------------------------------------- Handlebars.js adds a couple of additional features to make writing templates easier and also changes a tiny detail of how partials work. - [Nested Paths](http://handlebarsjs.com/#paths) - [Helpers](http://handlebarsjs.com/#helpers) - [Block Expressions](http://handlebarsjs.com/#block-expressions) - [Literal Values](http://handlebarsjs.com/#literals) - [Delimited Comments](http://handlebarsjs.com/#comments) Block expressions have the same syntax as mustache sections but should not be confused with one another. Sections are akin to an implicit `each` or `with` statement depending on the input data and helpers are explicit pieces of code that are free to implement whatever behavior they like. The [mustache spec](http://mustache.github.io/mustache.5.html) defines the exact behavior of sections. In the case of name conflicts, helpers are given priority. ### Compatibility There are a few Mustache behaviors that Handlebars does not implement. - Handlebars deviates from Mustache slightly in that it does not perform recursive lookup by default. The compile time `compat` flag must be set to enable this functionality. Users should note that there is a performance cost for enabling this flag. The exact cost varies by template, but it's recommended that performance sensitive operations should avoid this mode and instead opt for explicit path references. - The optional Mustache-style lambdas are not supported. Instead Handlebars provides its own lambda resolution that follows the behaviors of helpers. - Alternative delimiters are not supported. Supported Environments ---------------------- Handlebars has been designed to work in any ECMAScript 3 environment. This includes - Node.js - Chrome - Firefox - Safari 5+ - Opera 11+ - IE 6+ Older versions and other runtimes are likely to work but have not been formally tested. The compiler requires `JSON.stringify` to be implemented natively or via a polyfill. If using the precompiler this is not necessary. [![Selenium Test Status](https://saucelabs.com/browser-matrix/handlebars.svg)](https://saucelabs.com/u/handlebars) Performance ----------- In a rough performance test, precompiled Handlebars.js templates (in the original version of Handlebars.js) rendered in about half the time of Mustache templates. It would be a shame if it were any other way, since they were precompiled, but the difference in architecture does have some big performance advantages. Justin Marney, a.k.a. [gotascii](http://github.com/gotascii), confirmed that with an [independent test](http://sorescode.com/2010/09/12/benchmarks.html). The rewritten Handlebars (current version) is faster than the old version, with many [performance tests](https://travis-ci.org/wycats/handlebars.js/builds/33392182#L538) being 5 to 7 times faster than the Mustache equivalent. Upgrading --------- See [release-notes.md](https://github.com/wycats/handlebars.js/blob/master/release-notes.md) for upgrade notes.

Any JSON structure matching this pattern may be used and passed into the `compile` and `precompile` methods in the same way as the text for a template. AST structures may be generated either with the `Handlebars.parse` method and then manipulated, via the `Handlebars.AST` objects of the same name, or constructed manually as a generic JavaScript object matching the structure defined below. ```javascript var ast = Handlebars.parse(myTemplate); // Modify ast Handlebars.precompile(ast); ``` ### Basic ```java interface Node { type: string; loc: SourceLocation | null; } interface SourceLocation { source: string | null; start: Position; end: Position; } interface Position { line: uint >= 1; column: uint >= 0; } ``` ### Programs ```java interface Program <: Node { type: "Program"; body: [ Statement ]; blockParams: [ string ]; } ``` ### Statements ```java interface Statement <: Node { } interface MustacheStatement <: Statement { type: "MustacheStatement"; path: PathExpression | Literal; params: [ Expression ]; hash: Hash; escaped: boolean; strip: StripFlags | null; } interface BlockStatement <: Statement { type: "BlockStatement"; path: PathExpression; params: [ Expression ]; hash: Hash; program: Program | null; inverse: Program | null; openStrip: StripFlags | null; inverseStrip: StripFlags | null; closeStrip: StripFlags | null; } interface PartialStatement <: Statement { type: "PartialStatement"; name: PathExpression | SubExpression; params: [ Expression ]; hash: Hash; indent: string; strip: StripFlags | null; } interface PartialBlockStatement <: Statement { type: "PartialBlockStatement"; name: PathExpression | SubExpression; params: [ Expression ]; hash: Hash; program: Program | null; indent: string; openStrip: StripFlags | null; closeStrip: StripFlags | null; } ``` `name` will be a `SubExpression` when tied to a dynamic partial, i.e. `{{> (foo) }}`, otherwise this is a path or literal whose `original` value is used to lookup the desired partial. ```java interface ContentStatement <: Statement { type: "ContentStatement"; value: string; original: string; } interface CommentStatement <: Statement { type: "CommentStatement"; value: string; strip: StripFlags | null; } ``` ```java interface Decorator <: Statement { type: "Decorator"; path: PathExpression | Literal; params: [ Expression ]; hash: Hash; strip: StripFlags | null; } interface DecoratorBlock <: Statement { type: "DecoratorBlock"; path: PathExpression | Literal; params: [ Expression ]; hash: Hash; program: Program | null; openStrip: StripFlags | null; closeStrip: StripFlags | null; } ``` Decorator paths only utilize the `path.original` value and as a consequence do not support depthed evaluation. ### Expressions ```java interface Expression <: Node { } ``` ##### SubExpressions ```java interface SubExpression <: Expression { type: "SubExpression"; path: PathExpression; params: [ Expression ]; hash: Hash; } ``` ##### Paths ```java interface PathExpression <: Expression { type: "PathExpression"; data: boolean; depth: uint >= 0; parts: [ string ]; original: string; } ``` - `data` is true when the given expression is a `@data` reference. - `depth` is an integer representation of which context the expression references. `0` represents the current context, `1` would be `../`, etc. - `parts` is an array of the names in the path. `foo.bar` would be `['foo', 'bar']`. Scope references, `.`, `..`, and `this` should be omitted from this array. - `original` is the path as entered by the user. Separator and scope references are left untouched. ##### Literals ```java interface Literal <: Expression { } interface StringLiteral <: Literal { type: "StringLiteral"; value: string; original: string; } interface BooleanLiteral <: Literal { type: "BooleanLiteral"; value: boolean; original: boolean; } interface NumberLiteral <: Literal { type: "NumberLiteral"; value: number; original: number; } interface UndefinedLiteral <: Literal { type: "UndefinedLiteral"; } interface NullLiteral <: Literal { type: "NullLiteral"; } ``` ### Miscellaneous ```java interface Hash <: Node { type: "Hash"; pairs: [ HashPair ]; } interface HashPair <: Node { type: "HashPair"; key: string; value: Expression; } interface StripFlags { open: boolean; close: boolean; } ``` `StripFlags` are used to signify whitespace control character that may have been entered on a given statement. ## AST Visitor `Handlebars.Visitor` is available as a base class for general interaction with AST structures. This will by default traverse the entire tree and individual methods may be overridden to provide specific responses to particular nodes. Recording all referenced partial names: ```javascript var Visitor = Handlebars.Visitor; function ImportScanner() { this.partials = []; } ImportScanner.prototype = new Visitor(); ImportScanner.prototype.PartialStatement = function(partial) { this.partials.push({request: partial.name.original}); Visitor.prototype.PartialStatement.call(this, partial); }; var scanner = new ImportScanner(); scanner.accept(ast); ``` The current node's ancestors will be maintained in the `parents` array, with the most recent parent listed first. The visitor may also be configured to operate in mutation mode by setting the `mutation` field to true. When in this mode, handler methods may return any valid AST node and it will replace the one they are currently operating on. Returning `false` will remove the given value (if valid) and returning `undefined` will leave the node in tact. This return structure only apply to mutation mode and non-mutation mode visitors are free to return whatever values they wish. Implementors that may need to support mutation mode are encouraged to utilize the `acceptKey`, `acceptRequired` and `acceptArray` helpers which provide the conditional overwrite behavior as well as implement sanity checks where pertinent. ## JavaScript Compiler The `Handlebars.JavaScriptCompiler` object has a number of methods that may be customized to alter the output of the compiler: - `nameLookup(parent, name, type)` Used to generate the code to resolve a give path component. - `parent` is the existing code in the path resolution - `name` is the current path component - `type` is the type of name being evaluated. May be one of `context`, `data`, `helper`, `decorator`, or `partial`. Note that this does not impact dynamic partials, which implementors need to be aware of. Overriding `VM.resolvePartial` may be required to support dynamic cases. - `depthedLookup(name)` Used to generate code that resolves parameters within any context in the stack. Is only used in `compat` mode. - `compilerInfo()` Allows for custom compiler flags used in the runtime version checking logic. - `appendToBuffer(source, location, explicit)` Allows for code buffer emitting code. Defaults behavior is string concatenation. - `source` is the source code whose result is to be appending - `location` is the location of the source in the source map. - `explicit` is a flag signaling that the emit operation must occur, vs. the lazy evaled options otherwise. - `initializeBuffer()` Allows for buffers other than the default string buffer to be used. Generally needs to be paired with a custom `appendToBuffer` implementation. ```javascript function MyCompiler() { Handlebars.JavaScriptCompiler.apply(this, arguments); } MyCompiler.prototype = Object.create(Handlebars.JavaScriptCompiler); MyCompiler.nameLookup = function(parent, name, type) { if (type === 'partial') { return 'MyPartialList[' + JSON.stringify(name) ']'; } else { return Handlebars.JavaScriptCompiler.prototype.nameLookup.call(this, parent, name, type); } }; var env = Handlebars.create(); env.JavaScriptCompiler = MyCompiler; env.compile('my template'); ``` handlebars.js-4.0.5/docs/decorators-api.md000066400000000000000000000034521262352515600204370ustar00rootroot00000000000000# Decorators Decorators allow for blocks to be annotated with metadata or wrapped in functionality prior to execution of the block. This may be used to communicate with the containing helper or to setup a particular state in the system prior to running the block. Decorators are registered through similar methods as helpers, `registerDecorators` and `unregisterDecorators`. These can then be referenced via the friendly name in the template using the `{{* decorator}}` and `{{#* decorator}}{/decorator}}` syntaxes. These syntaxs are derivitives of the normal mustache syntax and as such have all of the same argument and whitespace behaviors. Decorators are executed when the block program is instantiated and are passed `(program, props, container, context, data, blockParams, depths)` - `program`: The block to wrap - `props`: Object used to set metadata on the final function. Any values set on this object will be set on the function, regardless of if the original function is replaced or not. Metadata should be applied using this object as values applied to `program` may be masked by subsequent decorators that may wrap `program`. - `container`: The current runtime container - `context`: The current context. Since the decorator is run before the block that contains it, this is the parent context. - `data`: The current `@data` values - `blockParams`: The current block parameters stack - `depths`: The current context stack Decorators may set values on `props` or return a modified function that wraps `program` in particular behaviors. If the decorator returns nothing, then `program` is left unaltered. The [inline partial](https://github.com/wycats/handlebars.js/blob/master/lib/handlebars/decorators/inline.js) implementation provides an example of decorators being used for both metadata and wrapping behaviors. handlebars.js-4.0.5/lib/000077500000000000000000000000001262352515600150135ustar00rootroot00000000000000handlebars.js-4.0.5/lib/handlebars.js000066400000000000000000000017211262352515600174550ustar00rootroot00000000000000import runtime from './handlebars.runtime'; // Compiler imports import AST from './handlebars/compiler/ast'; import { parser as Parser, parse } from './handlebars/compiler/base'; import { Compiler, compile, precompile } from './handlebars/compiler/compiler'; import JavaScriptCompiler from './handlebars/compiler/javascript-compiler'; import Visitor from './handlebars/compiler/visitor'; import noConflict from './handlebars/no-conflict'; let _create = runtime.create; function create() { let hb = _create(); hb.compile = function(input, options) { return compile(input, options, hb); }; hb.precompile = function(input, options) { return precompile(input, options, hb); }; hb.AST = AST; hb.Compiler = Compiler; hb.JavaScriptCompiler = JavaScriptCompiler; hb.Parser = Parser; hb.parse = parse; return hb; } let inst = create(); inst.create = create; noConflict(inst); inst.Visitor = Visitor; inst['default'] = inst; export default inst; handlebars.js-4.0.5/lib/handlebars.runtime.js000066400000000000000000000017131262352515600211400ustar00rootroot00000000000000import * as base from './handlebars/base'; // Each of these augment the Handlebars object.

If the helper uses the same context, then a new stack is not created. This leads to behavior that better matches expectations for helpers like `if` that do not seem to alter the context. Any instances of `../` in templates will need to be checked for the correct behavior under 4.0.0. In general templates will either reduce the number of `../` instances or leave them as is. See [#1028](https://github.com/wycats/handlebars.js/issues/1028). - The `=` character is now HTML escaped. This closes a potential exploit case when using unquoted attributes, i.e. `
`. In general it's recommended that attributes always be quoted when their values are generated from a mustache to avoid any potential exploit surfaces. - AST constructors have been dropped in favor of plain old javascript objects - The runtime version has been increased. Precompiled templates will need to use runtime of at least 4.0.0.

Compatibility notes: - The project now includes separate artifacts for AMD, CommonJS, and global objects. - AMD: Users may load the bundled `handlebars.amd.js` or `handlebars.runtime.amd.js` files or load individual modules directly. AMD users should also note that the handlebars object is exposed via the `default` field on the imported object. This [gist](https://gist.github.com/wycats/7417be0dc361a69d5916) provides some discussion of possible compatibility shims. - CommonJS/Node: Node loading occurs as normal via `require` - Globals: The `handlebars.js` and `handlebars.runtime.js` files should behave in the same manner as the v1.0.12 / 1.0.0 release. - Build artifacts have been removed from the repository. [npm][npm], [components/handlebars.js][components], [cdnjs][cdnjs], or the [builds page][builds-page] should now be used as the source of built artifacts. - Context-stored helpers are now always passed the `options` hash. Previously no-argument helpers did not have this argument. [Commits](https://github.com/wycats/handlebars.js/compare/v1.0.12...v1.1.0) ## v1.0.12 / 1.0.0 - May 31 2013 - [#515](https://github.com/wycats/handlebars.js/issues/515) - Add node require extensions support ([@jjclark1982](https://github.com/jjclark1982)) - [#517](https://github.com/wycats/handlebars.js/issues/517) - Fix amd precompiler output with directories ([@blessenm](https://github.com/blessenm)) - [#433](https://github.com/wycats/handlebars.js/issues/433) - Add support for unicode ids - [#469](https://github.com/wycats/handlebars.js/issues/469) - Add support for `?` in ids - [#534](https://github.com/wycats/handlebars.js/issues/534) - Protect from object prototype modifications - [#519](https://github.com/wycats/handlebars.js/issues/519) - Fix partials with . name ([@jamesgorrie](https://github.com/jamesgorrie)) - [#519](https://github.com/wycats/handlebars.js/issues/519) - Allow ID or strings in partial names - [#437](https://github.com/wycats/handlebars.js/issues/437) - Require matching brace counts in escaped expressions - Merge passed partials and helpers with global namespace values - Add support for complex ids in @data references - Docs updates Compatibility notes: - The parser is now stricter on `{{{`, requiring that the end token be `}}}`. Templates that do not follow this convention should add the additional brace value. - Code that relies on global the namespace being muted when custom helpers or partials are passed will need to explicitly pass an `undefined` value for any helpers that should not be available. - The compiler version has changed. Precompiled templates with 1.0.12 or higher must use the 1.0.0 or higher runtime.

See http://javascript.crockford.com/jsmin.html USE YOUR OWN COPY. IT IS EXTREMELY UNWISE TO LOAD CODE FROM SERVERS YOU DO NOT CONTROL. This file creates a global JSON object containing two methods: stringify and parse. JSON.stringify(value, replacer, space) value any JavaScript value, usually an object or array. replacer an optional parameter that determines how object values are stringified for objects. It can be a function or an array of strings. space an optional parameter that specifies the indentation of nested structures. If it is omitted, the text will be packed without extra whitespace. If it is a number, it will specify the number of spaces to indent at each level. If it is a string (such as '\t' or ' '), it contains the characters used to indent at each level. This method produces a JSON text from a JavaScript value. When an object value is found, if the object contains a toJSON method, its toJSON method will be called and the result will be stringified. A toJSON method does not serialize: it returns the value represented by the name/value pair that should be serialized, or undefined if nothing should be serialized. The toJSON method will be passed the key associated with the value, and this will be bound to the value For example, this would serialize Dates as ISO strings. Date.prototype.toJSON = function (key) { function f(n) { // Format integers to have at least two digits. return n < 10 ? '0' + n : n; } return this.getUTCFullYear() + '-' + f(this.getUTCMonth() + 1) + '-' + f(this.getUTCDate()) + 'T' + f(this.getUTCHours()) + ':' + f(this.getUTCMinutes()) + ':' + f(this.getUTCSeconds()) + 'Z'; }; You can provide an optional replacer method. It will be passed the key and value of each member, with this bound to the containing object. The value that is returned from your method will be serialized. If your method returns undefined, then the member will be excluded from the serialization. If the replacer parameter is an array of strings, then it will be used to select the members to be serialized. It filters the results such that only members with keys listed in the replacer array are stringified. Values that do not have JSON representations, such as undefined or functions, will not be serialized. Such values in objects will be dropped; in arrays they will be replaced with null. You can use a replacer function to replace those with JSON values. JSON.stringify(undefined) returns undefined. The optional space parameter produces a stringification of the value that is filled with line breaks and indentation to make it easier to read. If the space parameter is a non-empty string, then that string will be used for indentation. If the space parameter is a number, then the indentation will be that many spaces. Example: text = JSON.stringify(['e', {pluribus: 'unum'}]); // text is '["e",{"pluribus":"unum"}]' text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t'); // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]' text = JSON.stringify([new Date()], function (key, value) { return this[key] instanceof Date ? 'Date(' + this[key] + ')' : value; }); // text is '["Date(---current time---)"]' JSON.parse(text, reviver) This method parses a JSON text to produce an object or array. It can throw a SyntaxError exception. The optional reviver parameter is a function that can filter and transform the results. It receives each of the keys and values, and its return value is used instead of the original value. If it returns what it received, then the structure is not modified. If it returns undefined then the member is deleted. Example: // Parse the text. Values that look like ISO date strings will // be converted to Date objects. myData = JSON.parse(text, function (key, value) { var a; if (typeof value === 'string') { a = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value); if (a) { return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4], +a[5], +a[6])); } } return value; }); myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) { var d; if (typeof value === 'string' && value.slice(0, 5) === 'Date(' && value.slice(-1) === ')') { d = new Date(value.slice(5, -1)); if (d) { return d; } } return value; }); This is a reference implementation.
