JSDoc 3
|
|
=======
|
|
[](http://travis-ci.org/jsdoc3/jsdoc)
|
|
|
|
An inline API documentation processor for JavaScript. JSDoc 3 is intended to be
|
|
an upgrade to JsDoc Toolkit (JSDoc 2).
|
|

|
|
|
Installation
|
|
------------
|
|
|
|
Use git to clone the [official JSDoc repository](https://github.com/jsdoc3/jsdoc):
|
|
|
|
git clone git@github.com:jsdoc3/jsdoc.git
|
|
|
|
Alternatively, you can download a .zip file for the
|
|
[latest development version](https://github.com/jsdoc3/jsdoc/archive/master.zip)
|
|
or a [previous release](https://github.com/jsdoc3/jsdoc/tags).
|
|
|
|
You can also install JSDoc within a Node.js project's `node_modules` directory
|
|
using npm. To install the latest development version, change directories to your
|
|
Node.js project, then run the following command:
|
|
|
|
npm install git://github.com/jsdoc3/jsdoc.git
|
|
|
|
Or to install JSDoc globally:
|
|
|
|
npm install -g git://github.com/jsdoc3/jsdoc.git
|
|
|
|
**Note**: Although you can install JSDoc with npm, JSDoc does not currently run
|
|
on Node.js.
|
|
|
|
|
|
Usage
|
|
-----
|
|
|
|
This example assumes that your working directory is the JSDoc application base
|
|
directory:
|
|
|
|
./jsdoc yourSourceCodeFile.js
|
|
|
|
For information about the supported command-line options, use the `--help`
|
|
option.
|
|
|
|
./jsdoc --help
|
|
|
|
Generated documentation will appear in the folder specified by the
|
|
`--destination` option, or in a folder named "out" by default.
|
|
|
|
|
|
Dependencies
|
|
------------
|
|
|
|
JSDoc 3 uses the Mozilla Rhino engine, which requires Java. JSDoc 3 is known to
|
|
work with version 1.6.0_24 of Java.
|
|
|
|
JSDoc 3 uses advanced features in Mozilla Rhino that are only available in or
|
|
after version 1.7R3. In addition, JSDoc 3 requires several customizations to the
|
|
standard Rhino distribution. The customized version of Rhino is included with
|
|
JSDoc.
|
|
|
|
In rare cases, users may have their Java CLASSPATH configured to override the
|
|
included Rhino and point to an older version of Rhino instead. If this is the
|
|
case, simply correct the CLASSPATH to remove the older Rhino. (On OS X, you may
|
|
need to remove the file `~/Library/Java/Extensions/js.jar`.)
|
|
|
|
The version of Rhino distributed with JSDoc 3 can be found here:

Debugging
|
|
---------
|
|
|
|
Rhino is not always very friendly when it comes to reporting errors in
|
|
JavaScript. Luckily, it comes with a full-on debugger included that can be much
|
|
more useful than a simple stack trace. To invoke JSDoc with the debugger, run
|
|
the following command on Windows:
|
|
|
|
jsdoc --debug
|
|
|
|
Or on OS X, Linux, and other POSIX-compliant systems:
|
|
|
|
./jsdoc --debug
|
|
|
|
If you can't get the short-form commands to work, try invoking Java directly:
|
|
|
|
java -cp lib/js.jar org.mozilla.javascript.tools.debugger.Main \
|
|
-debug -modules node_modules -modules rhino -modules lib -modules . \
|
|
jsdoc.js your/script.js
|
|
|
|
Note: `--debug` must be the first argument to the short-form command.
|
|
|
|
This will open a debugging window. Click Debug > Break on Exceptions, then click
|
|
Run. If there is an error, you should see exactly where it is in the source
|
|
code.
