This library is a javascript LALR(1) parser that parses docblocks and extracts annotations under an structured syntax tree.
npm install doc-parser --saveAnd simple usage :
var DocParser = require('doc-parser');
var reader = new DocParser();
var data = reader.parse('/** @hello world */');/**
* Some description
* @return boolean
* @return map<string, SomeClass>
* @author Ioan CHIRIAC <[email protected]>
* @throws Exception
* @deprecated
* @table('tableName', true)
* @table(
* name='tableName',
* primary=true
* )
* @annotation1 @annotation2
* @Target(["METHOD", "PROPERTY"])
* @Attributes([
* @Attribute("stringProperty", type = "string"),
* @Attribute("annotProperty", type = "SomeAnnotationClass"),
* ])
* @json({
* "key": "value",
* "object": { "inner": true },
* "list": [1, 2, 3]
* })
* <node>
* Some inner multi line content
* </node>

kind: 'doc',
summary: 'Some description retrieved from the first line of the coment',
body: [
{
kind: 'return',
type: 'void',
description: 'Some extra informations'
}
]
}By default, doc-parser supports @return,@param,@throws and @deprecated
doc blocks.
You can extend the support to any doc block :
// lets handle @global (type) (var) (description)
var DocParser = require('doc-parser');
var reader = new DocParser({
'global': [
{
property: 'type',
parser: 'type',
optional: true
},
{
property: 'what',
parser: 'variable',
optional: true
},
{
property: 'description',
parser: 'text',
optional: true,
default: ''
}
]
});
var data = reader.parse('/** @global string some description */');This will result in a new kind of doc block with the specified properties. Here a list of supported parsers :
- type : a simple type, class name, or array of types
- variable : a variable name
- text : a line of text (will eat every token until the current line ends)
- version: a semantic version
- array : an array of items
- object : a json object definition
- boolean : a boolean
- number : a number (integer or float)
- string : a simple or double quoted text
