JSDoc 3

An inline API documentation processor for JavaScript. JSDoc 3 is intended to be an upgrade to JsDoc Toolkit (JSDoc 2).

Notice

This is beta software! It is available for testing purposes and may not be suitable for production use yet.

Installation

Download a copy of JSDoc 3 from the official Git Hub repository here: https://github.com/jsdoc3/jsdoc

To test that jsdoc is working, change your working directory to the jsdoc folder and run the following command:

java -cp lib/js.jar org.mozilla.javascript.tools.shell.Main \
-modules node_modules -modules rhino_modules \
jsdoc.js -T

If you are operating on a Mac OSX or *nix platform, you can shorten that command to this:

./jsdoc -T

Usage

This example assumes that your working directory is the jsdoc application base directory:

./jsdoc yourSourceCodeFile.js

For help regarding the supported commandline 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 utilises 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 the Rhino application which are only available in or after the 1.7 release 3. A copy of this version of Rhino is included in JSDoc so this is not normally an issue that the user needs to be concerned with. However, in rare cases, users may have their Java CLASSPATH configured to override that included Rhino and point to some older version of Rhino instead. If this is the case, simply correct the CLASSPATH to remove the older Rhino.

The version of rhino distributed with JSDoc3 can be found here: https://github.com/jannon/rhino

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 try the following command:

$ java -classpath lib/js.jar \
org.mozilla.javascript.tools.debugger.Main -debug \
-modules node_modules -modules rhino_modules \
jsdoc.js \
your/script.js

This will open a debugging window. Choose "Break on Exceptions" from the "Debug" menu, then press the "Run" button. If there is an error, you should see exactly where it is in the source code.
