json-lexer



This is a JSON lexer based on the implementation in json3.
It can split a JSON String into a list of annotated tokens. It will list whitespace
as well, so it can used in-place editing of JSON documents.

Note that this doesn't check the validity of your JSON, so it will tokenize something
like "token"}: happily.

``js
var lexer = require('json-lexer')
lexer('{"hello": 1.0}')
// results in
[ { type: 'punctuator', value: '{', raw: '{' },
{ type: 'string', value: 'hello', raw: '"hello"' },
{ type: 'punctuator', value: ':', raw: ':' },
{ type: 'whitespace', value: ' ', raw: ' ' },
{ type: 'number', value: 1, raw: '1.0' },
{ type: 'punctuator', value: '}', raw: '}' } ]
`
