TokenParser

TokenParser is a library to replace tokenized string. It has a build in extensible lexer to parse text and find expressions. By default, it will expect expressions encapsulated with [ and ], and will use angular-expression to parse the expressions.

Install

TokenParser is available for both node.js and browser environments, throught a browserified bundle available at dist/token-parser.js (and it's minified version).

NPM

Simply install it via npm install token-parser and use it with require('token-parser').

Bower

Install it with bower install token-parser and add it to your project with a common script tag. The TokenParser will be made available globally.

Usage

var TokenParser = require('token-parser');
var parser = new TokenParser();

// Do not forget to initialize it. This step is necessary so that extending
// lexer could be possible.
parser.init();

// "Text"
parser.replace('Text');

// "undefined" 
parser.replace('[foo]');

// "Text"
parser.replace('[foo]', {
  foo: 'Text'
});

// "Text"
parser.replace('[foo.bar]', {
  foo: {
    bar: 'Text'
  }
});

// "Text foo!"
parser.replace('Text [foo]', {
  foo: 'foo!'
});

// "Text"
parser.replace('[varia[foo]]', {
  foo: 'ble',
  variable: 'Text'
});

// FILTERS
//--------

parser.filter('uppercase', function (value) {
  return value.toUpperCase();
});

// "Text FOO!"
parser.replace('Text [foo|uppercase]', {
  foo: 'foo!'
});
