 - # Doctrine
 - 
 - Doctrine is a [JSDoc](http://usejsdoc.org) parser that parses documentation comments from JavaScript (you need to pass in the comment, not a whole JavaScript file).
 - 
 - ## Installation
 - 
 - You can install Doctrine using [npm](https://npmjs.com):
 - 
 - ```
 - $ npm install doctrine --save-dev
 - ```
 - 
 - Doctrine can also be used in web browsers using [Browserify](http://browserify.org).
 - 
 - ## Usage
 - 
 - Require doctrine inside of your JavaScript:
 - 
 - ```js
 - var doctrine = require("doctrine");
 - ```
 - 
 - ### parse()
 - 
 - The primary method is `parse()`, which accepts two arguments: the JSDoc comment to parse and an optional options object. The available options are:
 - 
 - * `unwrap` - set to `true` to delete the leading `/**`, any `*` that begins a line, and the trailing `*/` from the source text. Default: `false`.
 - * `tags` - an array of tags to return. When specified, Doctrine returns only tags in this array. For example, if `tags` is `["param"]`, then only `@param` tags will be returned. Default: `null`.
 - * `recoverable` - set to `true` to keep parsing even when syntax errors occur. Default: `false`.
 - * `sloppy` - set to `true` to allow optional parameters to be specified in brackets (`@param {string} [foo]`). Default: `false`.
 - * `lineNumbers` - set to `true` to add `lineNumber` to each node, specifying the line on which the node is found in the source. Default: `false`.
 - * `range` - set to `true` to add `range` to each node, specifying the start and end index of the node in the original comment. Default: `false`.
 - 
 - Here's a simple example:
 - 
 - ```js
 - var ast = doctrine.parse(
 -     [
 -         "/**",
 -         " * This function comment is parsed by doctrine",
 -         " * @param {{ok:String}} userName",
 -         "*/"
 -     ].join('\n'), { unwrap: true });
 - ```
 - 
 - This example returns the following AST:
 - 
 -     {
 -         "description": "This function comment is parsed by doctrine",
 -         "tags": [
 -             {
 -                 "title": "param",
 -                 "description": null,
 -                 "type": {
 -                     "type": "RecordType",
 -                     "fields": [
 -                         {
 -                             "type": "FieldType",
 -                             "key": "ok",
 -                             "value": {
 -                                 "type": "NameExpression",
 -                                 "name": "String"
 -                             }
 -                         }
 -                     ]
 -                 },
 -                 "name": "userName"
 -             }
 -         ]
 -     }

 - ## Frequently Asked Questions
 - 
 - ### Can I pass a whole JavaScript file to Doctrine?
 - 
 - No. Doctrine can only parse JSDoc comments, so you'll need to pass just the JSDoc comment to Doctrine in order to work.
