## 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-cache-breaker --save-dev
```
Once the plugin has been installed, add this to your Gruntfile.js

grunt.loadNpmTasks('grunt-cache-breaker');

And then add one of the following to your list of tasks

##Usage
###(all examples require version 1.0.0 or above)

**Append timestamps as query strings**

Very useful in the development stages, not to be used in production though (see the other examples)

```js
// Append a timestamp to 'all.min.js' & 'core.min.js' which are both located in 'index.html'
cachebreaker: {
    dev: {
        options: {
            match: ['all.min.js', 'core.min.css'],
        },
        files: {
            src: ['index.html']
        }
    }
}
```

**Append timestamps as filename changes**

A great idea if you have server rewrites. The file names are not changed, just changed in the markup.

File urls will be rewritten to `all.min.4252425.js`, for example

```js
// Append a timestamp to 'all.min.js' & 'core.min.js' which are both located in 'index.html'
cachebreaker: {
    dev: {
        options: {
            match: ['all.min.js', 'core.min.css'],
            position: 'filename'
        },
        files: {
            src: ['index.html']
        }
    }
}
```

**Append timestamps as filename changes in certain positions**

Again, to be used with server rewrites, this allows you specify which 'piece' of the filename is rewritten.

File urls will be rewritten to `all.4252425.js`, for example.

```js
// Append a timestamp to 'all.min.js' & 'core.min.js' which are both located in 'index.html'
cachebreaker: {
    dev: {
        options: {
            match: ['all.*.js', 'core.*.css'],
            position: 'overwrite'
        },
        files: {
            src: ['index.html']
        }
    }
}
```

##MD5 hash
Use the contents of a file to generate a hash instead of a timestamp. Works in all positions mentioned above.

This example will create links like this: `all.min.js?rel=hetweyj332` - which is useful as your templates only change
when the contents of the file change.

```js
// Append a md5 hash to 'all.js' which is located in 'index.html'
cachebreaker: {
    dev: {
        options: {
            match: ['all.js'],
            replacement: 'md5',
            src: {
                path: 'app/all.js'
            }
        },
        files: {
            src: ['index.html']
        }
    }
}
```

##Multiple MD5 hashs (v2.0.0 required)
Use the contents of multiple files to generate a hash for each.
NOTE: When passing an object to the `match` array like this, each `key`
is the pattern to search for in the html file & the value is the actual
file to be hashed.

If you're not sure, check the [Gruntfile.js](https://github.com/shakyShane/grunt-cache-breaker/blob/master/Gruntfile.js#L56-L69)
in this project for working examples.

```js
// Append a md5 hash to 'all.js' & `script.js` which is located in 'index.html'
cachebreaker: {
    dev: {
        options: {
            match: [
                {
                    // Pattern    // File to hash
                    'script.js': 'test/fixtures/js/script.js',
                    'app.js':    'test/fixtures/js/app.js'
                }
            ],
            replacement: 'md5'
        },
        files: {
            src: ['index.html']
        }
    }
}
```

##Custom replacement
You can also provide your own replacement if the Timestamps or MD5 hashes are not right for you.

This example would change the URL of app.js, to `app.js?rel=v_2_0`

```js
// Append a custom string to 'all.js' which is located in 'index.html'
cachebreaker: {
    dev: {
        options: {
            match: ['all.js'],
            replacement: function (){
                return "v_2_0"
            }
        },
        files: {
            src: ['index.html']
        }
    }
}
```

Of course, as with all examples, you're free to mix & match the options. For example, you could use
the custom method above, but to change the filename in the markup instead of a query string.

```js
// Change filename in the markup to include custom string
cachebreaker: {
    dev: {
        options: {
            match: ['all.js'],
            position: 'filename',
            replacement: function (){
                return "v_2_0"
            }
        },
        files: {
            src: ['index.html']
        }
    }
}
```

##Options

| Option      | Type            | Default  | Description                          |   |
|-------------|-----------------|----------|--------------------------------------|---|
| match       | string|array    | null     |                                      |   |
| replacement | string|function | "time"   | "time", "md5", or custom function    |   |
| position    | "string"        | "append" | "append", "filename", "overwrite"    |   |
| src.path    | "string"        | null     | Path to file to be used for md5 hash |   |
