Dox

Dox is a JavaScript documentation generator written with node. Dox no longer generates an opinionated structure or style for your docs, it simply gives you a JSON representation, allowing you to use markdown and JSDoc-style tags.

Modify in this dox

  • Support this kind of comment: multiLine tags, only split by \n@.You can use the multiLine option to open it.
  • Support markdown in @param and @return 's description.
  • Add exports.extractDoc function, accept a path of file, callback the dox Json.
/**
 * Description of this function 
 * @param {Object} options 
 * example:  
 *
  • {
  • raw: false,
  • multiLine: true
  • }
  • ```
  • @return {String} */ ```

Installation

Install from npm:

$ npm install dox-edp

Usage Examples

dox(1) operates over stdio:

$ dox < utils.js
...JSON... 

to inspect the generated data you can use the --debug flag, which is easier to read than the JSON output:

 $ dox --debug < utils.js 

utils.js:

/**
 * Escape the given `html`.
 *
 * Examples:
 *
 *     utils.escape('<script></script>')
 *     // => '&lt;script&gt;&lt;/script&gt;'
 *
 * @param {String} html string to be escaped
 * @return {String} escaped html
 * @api public
 */

exports.escape = function(html){
  return String(html)
    .replace(/&(?!\w+;)/g, '&amp;')
    .replace(/</g, '&lt;')
    .replace(/>/g, '&gt;');
};

output:

[
  {
    "tags": [
      {
        "type": "param",
        "types": [
          "String"
        ],
        "name": "html",
        "description": "string to be escaped"
      },
      {
        "type": "return",
        "types": [
          "String"
        ],
        "description": "escaped html"
      },
      {
        "type": "api",
        "visibility": "public"
      }
    ],
    "description": {
      "full": "<p>Escape the given <code>html</code>.</p>\n\n<h2>Examples</h2>\n\n<pre><code>utils.escape('&amp;lt;script&amp;gt;&amp;lt;/script&amp;gt;')\n// =&amp;gt; '&amp;lt;script&amp;gt;&amp;lt;/script&amp;gt;'\n</code></pre>",
      "summary": "<p>Escape the given <code>html</code>.</p>",
      "body": "<h2>Examples</h2>\n\n<pre><code>utils.escape('&amp;lt;script&amp;gt;&amp;lt;/script&amp;gt;')\n// =&amp;gt; '&amp;lt;script&amp;gt;&amp;lt;/script&amp;gt;'\n</code></pre>"
    },
    "isPrivate": false,
    "ignore": false,
    "code": "exports.escape = function(html){\n  return String(html)\n    .replace(/&(?!\\w+;)/g, '&amp;')\n    .replace(/</g, '&lt;')\n    .replace(/>/g, '&gt;');\n};",
    "ctx": {
      "type": "method",
      "receiver": "exports",
      "name": "escape",
      "string": "exports.escape()"
    }
  }
]

This output can then be passed to a template for rendering. Look below at the "Properties" section for details.

Usage


Usage: dox [options]

Options:

  -h, --help     output usage information
  -v, --version  output the version number
  -d, --debug    output parsed comments for debugging

Examples:

  # stdin
  $ dox > myfile.json

  # operates over stdio
  $ dox < myfile.js > myfile.json

Properties

A "comment" is comprised of the following detailed properties:

- tags
- description
- isPrivate
- ignore
- code
- ctx

Description

A dox description is comprised of three parts, the "full" description, the "summary", and the "body". The following example has only a "summary", as it consists of a single paragraph only, therefore the "full" property has only this value as well.

/**
 * Output the given `str` to _stdout_.
 */

exports.write = function(str) {
  process.stdout.write(str);
};
`

yields:

description: 
     { full: '<p>Output the given <code>str</code> to <em>stdout</em>.</p>',
       summary: '<p>Output the given <code>str</code> to <em>stdout</em>.</p>',
       body: '' },

Large descriptions might look something like the following, where the "summary" is still the first paragraph, the remaining description becomes the "body". Keep in mind this is markdown, so you can indent code, use lists, links, etc. Dox also augments markdown, allowing "Some Title:\n" to form a header.

/**
 * Output the given `str` to _stdout_
 * or the stream specified by `options`.
 * 
 * Options:
 * 
 *   - `stream` defaulting to _stdout_
 * 
 * Examples:
 * 
 *     mymodule.write('foo')
 *     mymodule.write('foo', { stream: process.stderr })
 * 
 */

exports.write = function(str, options) {
  options = options || {};
  (options.stream || process.stdout).write(str);
};

yields:

description: 
     { full: '<p>Output the given <code>str</code> to <em>stdout</em><br />or the stream specified by <code>options</code>.</p>\n\n<h2>Options</h2>\n\n<ul>\n<li><code>stream</code> defaulting to <em>stdout</em></li>\n</ul>\n\n<h2>Examples</h2>\n\n<pre><code>mymodule.write(\'foo\')\nmymodule.write(\'foo\', { stream: process.stderr })\n</code></pre>',
       summary: '<p>Output the given <code>str</code> to <em>stdout</em><br />or the stream specified by <code>options</code>.</p>',
       body: '<h2>Options</h2>\n\n<ul>\n<li><code>stream</code> defaulting to <em>stdout</em></li>\n</ul>\n\n<h2>Examples</h2>\n\n<pre><code>mymodule.write(\'foo\')\nmymodule.write(\'foo\', { stream: process.stderr })\n</code></pre>' }

Tags

Dox also supports JSdoc-style tags. Currently only @api is special-cased, providing the comment.isPrivate boolean so you may omit "private" utilities etc.


/**
 * Output the given `str` to _stdout_
 * or the stream specified by `options`.
 * 
 * @param {String} str
 * @param {Object} options
 * @return {Object} exports for chaining
 */

exports.write = function(str, options) {
  options = options || {};
  (options.stream || process.stdout).write(str);
  return this;
};

yields:

tags: 
   [ { type: 'param',
       types: [ 'String' ],
       name: 'str',
       description: '' },
     { type: 'param',
       types: [ 'Object' ],
       name: 'options',
       description: '' },
     { type: 'return',
       types: [ 'Object' ],
       description: 'exports for chaining' },
     { type: 'api',
       visibility: 'public' } ]

Code

The .code property is the code following the comment block, in our previous examples:

exports.write = function(str, options) {
  options = options || {};
  (options.stream || process.stdout).write(str);
  return this;
};

Ctx

The .ctx object indicates the context of the code block, is it a method, a function, a variable etc. Below are some examples:

exports.write = function(str, options) {
};

yields:

ctx: 
 { type: 'method',
   receiver: 'exports',
   name: 'write',
   string: 'exports.write()' } }
var foo = 'bar';

yields:

ctx: 
 { type: 'declaration',
   name: 'foo',
   value: '\'bar\'',
   string: 'foo' }
function User() {

}

yields:

ctx: 
 { type: 'function',
   name: 'User',
   string: 'User()' } }

Ignore

Comments and their associated bodies of code may be flagged with "!" to be considered worth ignoring, these are typically things like file comments containing copyright etc, however you of course can output them in your templates if you want.

/**
 * Not ignored.
 */

vs

/*!
 * Ignored.
 */
