grunt-strex

Grunt plugin to extract strings from javascript files, process them and export them all to an other file.

Getting Started

This plugin requires Grunt ~1.0.0

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-strex --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-strex');

In your project's Gruntfile, add a section named strex to the data object passed into grunt.initConfig().

grunt.initConfig({
  strex: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
});

Usage Examples

If you have a file src/testing.js with content:

var tags = [
  "@title Hello",
  "@name Sexy"
];

Using this options:

grunt.initConfig({
  strex: {
    options: {
      match: /^.@(.*) (.*)./,
      replace: "$1: $2",
      separator: ", ",
      ecmaVersion: 5,
      comment: false
    },
    files: {
      'dest/result.txt': ['src/testing.js'],
    },
  },
});

You extract all strings of the src/testing.js file to the resulting dest/result.txt:

title: Hello, name: Sexy
