Automate documentation of Actions and Filters in WordPress. This npm module needs the JSDoc3 module as dependency. It uses JSDoc3 as comment parser and generates a documentation with the power of JSDoc.

Simply install via:

$ npm install jsdoc -g
$ npm install wp-hookdoc --save-dev

In your JSDoc configuration file hookdoc-conf.json the following options are essential (create a seperate configuration file if you already use JSDoc):

{
    "opts": {
        "template": "node_modules/wp-hookdoc/template"
    },
    "source": {
        "includePattern": ".+\\.(php|inc)?$"
    },
    "plugins": [
        "node_modules/wp-hookdoc/plugin"
    ]
}

Run your jsdoc command with the input files and -c hookdoc-conf.json.

Define @hook attribute with the name of the action:

<?php
/**
 * Enqueue scripts for all admin pages.
 *
 * @since 2.8.0
 * @hook admin_enqueue_scripts
 * @param {string} $hook_suffix The current admin page.
 */
do_action( 'admin_enqueue_scripts', $hook_suffix );

Define @hook attribute with the name of the filter and a @returns attribute:

/**
 * Filters the title tag content for an admin page.
 *
 * @since 3.1.0
 * @hook admin_title
 * @param {string} $admin_title The page title, with extra context added.
 * @param {string} $title       The original page title.
 * @returns {string} The title
 */
$admin_title = apply_filters( 'admin_title', $admin_title, $title );

To generate an example documentation change to the node_modules/wp-hookdoc folder and run:

npm run example

You will find the output in node_modules/wp-hookdoc/example/out:
