# grunt-properties [![Build Status](http://img.shields.io/travis/heldr/grunt-properties/master.svg?style=flat)](http://travis-ci.org/heldr/grunt-properties)

> Convert java [.properties](http://en.wikipedia.org/wiki/.properties) files to javascript

> "JavaScript isn't a great way to store configuration data. That's because the syntax is still that of a programming language, so you need to be sure you haven't introduced syntax errors. If you end up concatenating JavaScript files together, a syntax error in a single line breaks the overall application"
*( Nicholas C. Zakas, [Maintainable JavaScript, Writing Readable Code, O'Reilly Media, May 2012](http://shop.oreilly.com/product/0636920025245.do))*

## Getting Started
This plugin requires Grunt `~0.4.1`

If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to create a [Gruntfile](http://gruntjs.com/sample-gruntfile) as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

```shell
npm install grunt-properties --save-dev
```

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

```js
grunt.loadNpmTasks('grunt-properties');
```

## The "properties" task

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

```js
grunt.initConfig({
  properties: {
    page_config: {
      files: {
        'tmp/page_config.js': ['test/fixtures/page_config.properties'],
      },
    },
    page_color_config: {
      options: {
        namespace: 'mypage'
      },
      files: {
        'tmp/page_color_config.js': ['test/fixtures/page_config.properties', 'test/fixtures/page_color_config.properties'],
      },
    },
  },
})
```

### Options

#### options.namespace
Type: `String`
Default value: `'config'`

Use a previously defined namespace.

### Usage Examples

#### Default namespace config
```js
grunt.initConfig({
  properties: {
    options: {},
    files: {
      'tmp/page_config.js': ['test/fixtures/page_config.properties'],
    },
  },
})
```

#### Customized namespace
```js
grunt.initConfig({
  properties: {
    page_color_config: {
      options: {
        namespace: 'mypage'
      },
      files: {
        'tmp/page_color_config.js': ['test/fixtures/page_config.properties', 'test/fixtures/page_color_config.properties'],
      },
    },
  },
})
```
