# JSDoc 3 change history This file describes notable changes in each version of JSDoc 3. To download a specific version of JSDoc 3, see [GitHub's tags page](https://github.com/jsdoc3/jsdoc/tags). ## 3.3.0 (January 2015) **Note**: This draft changelog is current through January 21, 2015, and is subject to change before JSDoc 3.3.0 is released. ### Major changes + You can now run JSDoc on Node.js. (#93) + You can now use the `@interface` and `@implements` tags to document interfaces and their implementations. (#720, #828) + Closure Compiler's `@inheritDoc` and `@override` tags are now supported. (#53) + If the JSDoc comment for a symbol includes the `@mixes` tag, all of the mixins now appear in the symbol's documentation. (#378) + JSDoc can now log information to the console as it runs (for example, the name of each file that JSDoc parses). To log this information, run JSDoc with the `--verbose` flag. (#416) + You can now use any file as the package or README file for your documentation. Use the `-P/--package/` and `-R/--readme` flags to specify the package and README file. (#708) + The default template's typography and color scheme have been significantly improved. (#550, #780, #843) ### Enhancements + You can now use the `--pedantic` flag to treat all errors as fatal errors, and to treat warnings as errors. This flag replaces the `--lenient` flag, which had roughly the opposite meaning and is no longer available. (#416) + You can now use the `-a/--access` flag to control whether private, protected, and public symbols appear in the documentation. (#860, #861) + You can now use the `--debug` flag to log detailed debugging information to the console. This information can help you diagnose bugs in JSDoc itself. (#416) + JSDoc's configuration file can now contain JavaScript comments. (#660) + You can now include source files from a directory, but exclude one of its subdirectories, by adding the subdirectory to the `source.exclude` option in the configuration file. (#484) + The `source.exclude` option now works correctly when JSDoc is run with the `-r/--recurse` flag. (#616) + When JSDoc is run with the `-r/--recurse` flag, it now scans for tutorials recursively. (#712) + JSDoc's `-X/--explain` option now runs much more quickly. (#633) + If all of the text for an `@example` tag is indented, JSDoc now removes the extra indentation. (#540) + The default value for a parameter or property can now include brackets (for example, `@param {Array.} [foo=['bar']]`). (#640) + You can now provide a default value for parameters and properties that are not optional (for example, `@property {string} foo='bar'`). (#791) + If the `@type` tag includes a description (for example, `@type {string} some text`), JSDoc now parses the type expression correctly and discards the description. (#615) + You can now add JSDoc comments to function parameters. (#473) + For Closure Compiler projects, you can now enable a Closure Compiler-specific tag dictionary that more closely matches Closure Compiler's semantics. To enable Closure Compiler semantics, set the configuration file's `tags.dictionaries` option to `['closure']`. This option can contain the values `jsdoc`, `closure`, or both. If multiple dictionaries are enabled, and a tag is defined in more than one dictionary, JSDoc uses the definition from the first dictionary that contains the tag. (#729, #730, #731, #732) + If one symbol overrides another, JSDoc now adds an `overrides` property to the doclet that is overriding another. The `overrides` property contains the longname of the overridden symbol. (#792) + When a JSDoc tag contains a type expression, the doclet's `type` object now includes a hidden `parsedType` property. The `parsedType` property contains a syntax tree that represents the type expression. The syntax tree is generated by [Catharsis](https://github.com/hegemonic/catharsis), and its format may change in the future. (#576) + JSDoc now allows output filenames to contain non-ASCII characters. In addition, links to output files are now URL-encoded when necessary. (#677) + JSDoc now ensures that output filenames do not have a leading underscore. (#758) + JSDoc now tries to ensure that `id` attributes in output files are unique within that file. (#539) + JSDoc now has an up-to-date JSON Schema file for parse results. The schema file is available in `lib/jsdoc/schema.js`. (#327) + JSDoc now extracts more information from package files. (#710) + JSDoc now displays usage information if you run JSDoc without any input files, or with an unrecognized command-line option. (#609, #840) ### Bug fixes + When the `allowUnknownTags` option is set to `false`, JSDoc no longer logs warnings about the presence of `@also` and `@scope` tags. (#574) + Fixed several errors when parsing type expressions. (#619, #644, #652, #705, #767) + Properties added to the `module.exports` object can now be documented. (#500) + When a symbol's name starts with the same characters as its parent namespace (such as `Vector` in `V.Vector`), JSDoc now assigns the correct longname to the symbol. (#608) + If a child class inherits from multiple parent classes, and the parent classes have instance members with the same name, the child class no longer displays the documentation from both parent classes. (#613) + If a source file contains an object literal, and one of the property names is a whitespace character or a character that must be escaped in a regular expression, JSDoc now parses the file successfully. (#549, #775) + Virtual comments now work correctly for overloaded functions. (#727) + When a virtual comment appears within a module, JSDoc now assigns the correct values to the virtual comment doclet's `memberof`, `longname`, and `scope` properties. (#631) + JSDoc now sets the `scope` property to `global` for all global doclets. (#684) + Module doclets no longer have a `scope` property. (#782) + In Markdown tutorials, JSDoc no longer unescapes HTML entities. (#743) + If a longname includes a variation (for example, `Foo#bar(variation)`), the link text is now preserved when generating HTML links. (#857) + When a single JSDoc comment includes `@class`, `@classdesc`, and `@constructor` tags, JSDoc no longer ignores the value of the `@classdesc` tag. (#806) + For tags where the name and type are both optional (`@constant`, `@external`, `@member`, `@module`, `@namespace`, and `@param`), JSDoc now parses the tag correctly when it includes a type but not a name. (#351, #535) + The `@default` tag now works correctly when used with an array literal. (#604) + The `@enum` tag now works correctly when the enumeration is part of a chain of assignments (for example, `var FOO = exports.FOO = {/* enumerated values */}`). (#702) + The `@exports` and `@module` tags now work correctly when their value includes a `module:` namespace (for example, `@exports module:foo`). (#786) + The `@memberof` tag now works correctly when it refers to a module that is defined in a separate file. (#880) + The `@variation` tag now works correctly when its value is enclosed in parentheses (for example, `@variation (foo)`). (#850) ### Plugins + Tag definitions can now have a `mustNotHaveDescription` property. When this property is set to `true`, JSDoc will warn the user if the tag text includes a description (such as `The description` in `@param {string} foo - The description`). (#615) + Tag definitions can now call the method `dictionary.normalize`, which is a synonym for `dictionary.normalise`. (#884) + The Markdown plugin no longer prevents inline `{@link}` tags from working. (#518) + The Markdown plugin now converts `@author` and `@throws` tag values to HTML by default. (#736, #878) + JSDoc now includes a `summarize` plugin that automatically generates summaries based on the description. (#485) + JSDoc now includes an `underscore` plugin that finds symbols whose names begin with an underscore and automatically tags them as `@private`. (#471) + Plugins can now replace the `doclet` property of `newDoclet` events. (#584) ### Template improvements + You can now override the default template's main layout file, `layout.tmpl`, by setting the `templates.default.layoutFile` option in JSDoc's configuration file. The property can contain a relative or absolute path to the replacement for `layout.tmpl`. Relative paths are resolved against the path to the configuration file; the current working directory; and the JSDoc directory, in that order. (#480) + When the `templates.default.outputSourceFiles` option is set to `false`, the documentation no longer shows the path to each source file. (#571) + You can now use the property `templates.default.staticFiles.include` to list files that will be copied to the output directory. For backwards compatibility, the property `templates.default.staticFiles.paths` is also supported but is deprecated. (#785) + The `templates.default.staticFiles` options now work correctly on Windows. (#785) + Output files no longer show the default value for members of an enumeration. (#689) + In certain types of AMD modules, the module-overview section is no longer duplicated. (#853) + If a constructor is assigned to `module.exports`, the value of the `@classdesc` tag now appears in the documentation. (#740) + If a constructor is assigned to `module.exports`, and the constructor inherits from another class, the parent class is now listed in the documentation. (#594) + Text within an `@example` tag, including HTML tags, is now properly escaped. (#511) + If a member has a `@fires` tag, the tag information now appears in the documentation. (#568) + If a symbol has members that use the `@mixin` tag, the mixins are now listed in the documentation. (#379, #602) + When multiple `@param` tags are used to document properties of array values (for example, `@param {Object[]} foo` and `@param {string} foo[].bar`), the properties are now grouped into the appropriate row of the parameters table. (#870) + If a member has a `@requires` tag, the tag information now appears in the documentation. (#563) + Type expressions are now presented more clearly. (#618) + Pretty-printed source files now include line numbers. (#532) + When you run JSDoc with a single input file, the full path to the file no longer appears in the documentation. (#553) + When an overloaded function is assigned to `module.exports`, the documentation now displays all of the signatures for the overloaded function. (#727) + Resolved several issues that caused the default template to generate invalid HTML. (#843) ## 3.2.2 (November 2013) ### Bug fixes + Addressed a regression in JSDoc 3.2.1 that could prevent a function declaration from shadowing a declaration with the same name in an outer scope. (#513) + If a child class overrides a method in a parent class without documenting the overridden method, the method's documentation is now copied from the parent class. (#503) + You can now use inline HTML tags in Markdown-formatted text. In addition, JSDoc now uses only the [marked Markdown parser](https://github.com/chjj/marked); the markdown-js parser has been removed. (#510) + Type expressions can now include a much broader range of repeatable types. In addition, you can now use Closure Compiler's nullable and non-nullable modifiers with repeatable types. For example, the type expression `...!string` (a repeatable, non-nullable string) is now parsed correctly. (#502) + If a function accepts a parameter named `prototype`, the parameter is no longer renamed during parsing. (#505) + If the list of input files includes relative paths, the paths are now resolved relative to the user's working directory. (a3d33842) ## 3.2.1 (October 2013) ### Enhancements + JSDoc's parser now fires a `processingComplete` event after JSDoc has completed all post-processing of the parse results. This event has a `doclets` property containing an array of doclets. (#421) + When JSDoc's parser fires a `parseComplete` event, the event now includes a `doclets` property containing an array of doclets. (#431) + You can now use relative paths in the JSDoc configuration file's `source.exclude` option. Relative paths will be resolved relative to the current working directory. (#405) + If a symbol uses the `@default` tag, and its default value is an object literal, this value is now stored as a string, and the doclet will have a `defaultvaluetype` property containing the string `object`. This change enables templates to show the default value with appropriate syntax highlighting. (#419) + Inline `{@link}` tags can now contain newlines. (#441) ### Bug fixes + Inherited symbols now indicate that they were inherited from the ancestor that defined the symbol, rather than the direct parent. (#422) + If the first line of a JavaScript file contains a hashbang (for example, `#!/usr/bin/env node`), the hashbang is now ignored when the file is parsed. (#499) + Resolved a crash when a JavaScript file contains a [JavaScript 1.8](https://developer.mozilla.org/en-US/docs/Web/JavaScript/New_in_JavaScript/1.8) keyword, such as `let`. (#477) + The type expression `function[]` is now parsed correctly. (#493) + If a module is tagged incorrectly, the module's output file now has a valid filename. (#440, #458) + For tags that accept names, such as `@module` and `@param`, if a hyphen is used to separate the name and description, the hyphen must appear on the same line as the name. This change prevents a Markdown bullet on the followng line from being interpreted as a separator. (#459) + When lenient mode is enabled, a `@param` tag with an invalid type expression no longer causes a crash. (#448) + The `@requires` tag can now contain an inline tag in its tag text. (#486) + The `@returns` tag can now contain inline tags even if a type is not specified. (#444) + When lenient mode is enabled, a `@returns` tag with no value no longer causes a crash. (#451) + The `@type` tag now works correctly with type expressions that span multiple lines. (#427) + If a string contains inline `{@link}` tags preceded by bracketed link text (for example, `[test]{@link Test#test}`), HTML links are now generated correctly even if the string contains other bracketed text. (#470) + On POSIX systems, if you run JSDoc using a symlink to the startup script, JSDoc now works correctly. (#492) ### Default template + Pretty-printed source files are now generated by default. To disable this feature, add the property `templates.default.outputSourceFiles: false` to your `conf.json` file. (#454) + Links to a specific line in a source file now work correctly. (#475) + Pretty-printed source files are now generated using the encoding specified in the `-e/--encoding` option. (#496) + If a `@default` tag is added to a symbol whose default value is an object, the value is now displayed in the output file. (#419) + Output files now identify symbols as "abstract" rather than "virtual." (#432) ## 3.2.0 (May 2013) ### Major changes + JSDoc can now parse any valid [Google Closure Compiler type expression](https://developers.google.com/closure/compiler/docs/js-for-compiler#types). **Note**: As a result of this change, JSDoc quits if a file contains an invalid type expression. To prevent JSDoc from quitting, run JSDoc with the `--lenient` (`-l`) command-line option. (Multiple issues) + You can now use the new `@listens` tag to indicate that a symbol listens for an event. (#273) ### Enhancements + The parser now fires a `parseBegin` event before it starts parsing files, as well as a `parseComplete` event after all files have been parsed. Plugins can define event handlers for these events, and `parseBegin` handlers can modify the list of files to parse. (#299) + Event handlers for `jsdocCommentFound` events can now modify the JSDoc comment. (#228) + You can now exclude tags from Markdown processing using the new option `markdown.excludeTags` in the configuration file. (#337) + You can now use the [marked](https://github.com/chjj/marked) Markdown parser by setting the configuration property `markdown.parser` to `marked`. In addition, if `markdown.parser` is set to `gfm`, JSDoc will now use the "marked" parser instead. (#385) + The `@typedef` tag no longer requires a name when used with a Closure Compiler-style type definition. For example, the following type definition will automatically get the name `Foo.Bar`: ```javascript /** @typedef {string} */ Foo.Bar; ``` (#391) + You can now use an inline `{@type}` tag in a parameter's description. If this tag is present, JSDoc will assume that the parameter uses the type specified in the inline `{@type}` tag. For example, the following `@param` tag would cause `myParam`'s type to be documented as `Foo`: ``` @param {(boolean|string)} myParam - My special parameter. {@type Foo} ``` (#152) + The `console.log` function now behaves the same way as on Node.js. In addition, the functions `console.info`, `console.error`, `console.warn`, and `console.trace` have been implemented. (#298) + You can now use npm to install JSDoc globally by running `npm install -g`. **Note**: JSDoc will still run under Mozilla Rhino, not Node.js. (#374) + The `jsVersion` configuration property has been removed. (#390) ### Bug fixes + JSDoc now quits if the configuration file cannot be loaded. (#407) + JSDoc's `--explain` (`-X`) option now runs much more quickly, and it outputs valid JSON to the console. (#298) + JSDoc's `--lenient` (`-l`) option now prints warnings on STDERR rather than STDOUT. (#298) + The parser now assigns the correct scope to object properties whose names include single quotes. (#386) + The parser now recognizes CommonJS modules that export a single function rather than an object. (#384) + The inline `{@link}` tag now works correctly when `@link` is followed by a tab. (#359) + On POSIX systems, quoted command-line arguments are no longer split on spaces. (#397) ### Plugins + The new `overloadHelper` plugin makes it easier to link to overloaded methods. (#179) + The `markdown` plugin now converts Markdown links in the `@see` tag. (#297) ### Default template enhancements + You can now use the configuration property `templates.default.staticFiles` to copy additional static files to the output directory. (#393) + All output files now use human-readable filenames. (#339) + The documentation for events now lists the symbols that listen to that event. (#273) + Links to source files now allow you to jump to the line where a symbol is defined. (#316) + The output files now link to individual types within a Closure Compiler type expression. (Multiple issues) + CommonJS modules that export a single function, rather than an object, are now documented more clearly. (#384) + Functions that can throw multiple types of errors are now documented more clearly. (#389) + If a `@property` tag does not identify the property's name, the template no longer throws an error. (#373) + The type of each `@typedef` is now displayed. (#391) + If a `@see` tag contains a URL (for example, `@see http://example.com` or `@see `), the tag text is now converted to a link. (#371) + Repeatable parameters are now identified. (#381) + The "Classes" header is no longer repeated in the navigation bar. (#361) + When the only documented symbols in global scope are type definitions, you can now click the "Global" header to view their documentation. (#261) ## 3.1.1 (February 2013) + Resolved a crash when no input files contain JSDoc comments. (#329) + Resolved a crash when JSDoc cannot identify the common prefix of several paths. (#330) + Resolved a crash when the full path to JSDoc contained at least one space. (#347) + Files named `README.md` or `package.json` will now be processed when they are specified on the command line. (#350) + You can now use `@emits` as a synonym for `@fires`. (#324) + The module `jsdoc/util/templateHelper` now allows you to specify the CSS class for links that are generated by the following methods: (#331) + `getAncestorLinks` + `getSignatureReturns` + `getSignatureTypes` + `linkto` ## 3.1.0 (January 2013) ### Major changes + You can now use the new `@callback` tag to provide information about a callback function's signature. To document a callback function, create a standalone JSDoc comment, as shown in the following example: ```javascript /** * @class */ function MyClass() {} /** * Send a request. * * @param {MyClass~responseCb} cb - Called after a response is received. */ MyClass.prototype.sendRequest = function(cb) { // code }; /** * Callback for sending a request. * * @callback MyClass~responseCb * @param {?string} error - Information about the error. * @param {?string} response - Body of the response. */ ``` + The inline link tag, `{@link}`, has been improved: + You can now use a space as the delimiter between the link target and link text. + In your `conf.json` file, you can now enable the option `templates.cleverLinks` to display code links in a monospace font and URL links in plain text. You can also enable the option `templates.monospaceLinks` to display all links in a monospace font. **Note**: JSDoc templates must be updated to respect these options. + You can now use the new inline tags `{@linkplain}`, which forces a plain-text link, and `{@linkcode}`, which forces a monospace link. These tags always override the settings in your `conf.json` file. (#250) + JSDoc now provides a `-l/--lenient` option that tells JSDoc to continue running if it encounters a non-fatal error. (Multiple issues) + A template's `publish.js` file should now assign its `publish` function to `exports.publish`, rather than defining a global `publish` function. The global `publish` function is deprecated and may not be supported in future versions. JSDoc's built-in templates reflect this change. (#166) + The template helper (`templateHelper.js`) exports a variety of new functions for finding information within a parse tree. These functions were previously contained within the default template. (#186) + Updated the `fs` and `path` modules to make their behavior more consistent with Node.js. In addition, created extended versions of these modules with additional functionality. (Multiple commits) + Updated or replaced numerous third-party modules. (Multiple commits) + Reorganized the JSDoc codebase in preparation for future enhancements. (Multiple commits) + JSDoc now embeds a version of Mozilla Rhino that recognizes Node.js packages, including `package.json` files. (Multiple commits) + Node.js' `npm` utility can now install JSDoc from its GitHub repository. **Note**: JSDoc is not currently compatible with Node.js. However, this change allows JSDoc to be installed as a dependency of a Node.js project. In this version, global installation with `npm` is not supported. (Multiple commits) ### Enhancements + If a `README.md` file is passed to JSDoc, its contents will be included on the `index.html` page of the generated documentation. (#128) + The `@augments` tag can now refer to an undocumented member, such as `window.XMLHTTPRequest`. (#160) + The `@extends` tag can now refer to an undocumented member, such as `window.XMLHttpRequest`. In addition, you can now use `@host` as a synonym for `@extends`. (#145) + The `@lends` tag is now supported in multiline JSDoc comments. (#163) + On Windows, `jsdoc.cmd` now provides the same options as the `jsdoc` shell script. (#127) + JSDoc now provides `setTimeout()`, `clearTimeout()`, `setInterval()`, and `clearInterval()` functions. (Multiple commits) + JSDoc no longer provides a global `exit()` function. Use `process.exit()` instead. (1228a8f7) + JSDoc now includes additional shims for Node.js' built-in modules. **Note**: Many of these shims implement only the functions that JSDoc uses, and they may not be consistent with Node.js' behavior in edge cases. (Multiple commits) + JSDoc now provides a `-v/--version` option to display information about the current version. (#303) + When running tests, you can now use the `--nocolor` option to disable colored output. On Windows, colored output is always disabled. (e17601fe, 8bc33541) ### Bug fixes + When using the `@event` tag to define an event within a class or namespace, the event's longname is now set correctly regardless of tag order. (#280) + The `@property` tag no longer results in malformed parse trees. (20f87094) + The `jsdoc` and `jsdoc.cmd` scripts now work correctly with paths that include spaces. (#127, #130) + The `jsdoc` script now works correctly on Cygwin and MinGW, and with the `dash` shell. (#182, #184, #187) + The `-d/--destination` option is no longer treated as a path relative to the JSDoc directory. Instead, it can contain an absolute path, or a path relative to the current working directory. (f5e3f0f3) + JSDoc now provides default options for the values in `conf.json`. (#129) + If the `conf.json` file does not exist, JSDoc no longer tries to create it, which prevents errors if the current user does not have write access to the JSDoc directory. (d2d05fcb) + Doclets for getters and setters are now parsed appropriately. (#150) + Only the first asterisk is removed from each line of a JSDoc comment. (#172) + If a child member overrides an ancestor member, the ancestor member is no longer documented. (#158) + If a member of a namespace has the same name as a namespace, the member is now documented correctly. (#214) + The parse tree now uses a single set of properties to track both JSDoc-style type information and Closure Compiler-style type information. (#118) + If a type has a leading `!`, indicating that it is non-nullable, the leading `!` is now removed from the type name. (#226) + When Markdown formatting is enabled, underscores in inline `{@link}` tags are no longer treated as Markdown formatting characters. (#259) + Markdown links now work correctly when a JavaScript reserved word, such as `constructor`, is used as the link text. (#249) + Markdown files for tutorials are now parsed based on the settings in `conf.json`, rather than using the "evilstreak" Markdown parser in all cases. (#220) + If a folder contains both tutorial source files and `.js` files, JSDoc no longer attempts to parse the `.js` files as JSON files. (#222) + The "evilstreak" Markdown parser now works correctly with files that use Windows-style line endings. (#223) + JSDoc no longer fails unit tests when the `conf.json` file is not present. (#206) + On Windows, JSDoc now passes all unit tests. (Multiple commits) ### Plugins + The new `partial` plugin adds support for a `@partial` tag, which links to an external file that contains JSDoc comments. (#156) + The new `commentsOnly` plugin removes everything in a file except JSDoc-style comments. You can use this plugin to document source files that are not valid JavaScript, including source files for other languages. (#304) + The new `eventDumper` plugin logs information about parser events to the console. (#242) + The new `verbose` plugin logs the name of each input file to the console. (#157) ### Template enhancements #### Default template + The template output now includes pretty-printed versions of source files. This feature is enabled by default. To disable this feature, add the property `templates.default.outputSourceFiles: false` to your `conf.json` file. (#208) + You can now use the template if it is placed outside of the JSDoc directory. (#198) + The template no longer throws an error when a parameter does not have a name. (#175) + The navigation bar now includes an "Events" section if any events are documented. (#280) + Pages no longer include a "Classes" header when no classes are documented. (eb0186b9) + Member details now include "Inherited From" section when a member is inherited from another member. (#154) + If an `@author` tag contains text in the format "Jane Doe ", the value is now converted to an HTML `mailto:` link. (#326) + Headings for functions now include the function's signature. (#253) + Type information is now displayed for events. (#192) + Functions now link to their return type when appropriate. (#192) + Type definitions that contain functions are now displayed correctly. (#292) + Tutorial output is now generated correctly. (#188) + Output files now use Google Code Prettify with the Tomorrow theme as a syntax highlighter. (#193) + The `index.html` output file is no longer overwritten if a namespace called `index` has been documented. (#244) + The current JSDoc version number is now displayed in the footer. (#321) #### Haruki template + Members are now contained in arrays rather than objects, allowing overloaded members to be documented. (#153) + A clearer error message is now provided when the output destination is not specified correctly. (#174) ## 3.0.1 (June 2012) ### Enhancements + The `conf.json` file may now contain `source.include` and `source.exclude` properties. (#56) + `source.include` specifies files or directories that JSDoc should _always_ check for documentation. + `source.exclude` specifies files or directories that JSDoc should _never_ check for documentation. These settings take precedence over the `source.includePattern` and `source.excludePattern` properties, which contain regular expressions that JSDoc uses to search for source files. + The `-t/--template` option may now specify the absolute path to a template. (#122) ### Bug fixes + JSDoc no longer throws exceptions when a symbol has a special name, such as `hasOwnProperty`. (1ef37251) + The `@alias` tag now works correctly when documenting inner classes as globals. (810dd7f7) ### Template improvements + The default template now sorts classes by name correctly when the classes come from several modules. (4ce17195) + The Haruki template now correctly supports `@example`, `@members`, and `@returns` tags. (6580e176, 59655252, 31c8554d) ## 3.0.0 (May 2012) Initial release.
