grunt-commenthash

Calculates a unique hash of a file. This hash will be added as a comment to javascript, CSS, PHP and HTML files.

Getting Started

This plugin requires Grunt ~0.4.0

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-commenthash --save-dev

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

grunt.loadNpmTasks('grunt-commmenthash');

This plugin was designed to work with Grunt 0.4.x. If you're still using grunt v0.3.x it's strongly recommended that you upgrade.

			hashFunction: function(source, encoding){ // default is md5
				return require('crypto').createHash('sha1').update(source, encoding).digest('hex');
			},
      footer: '<%= grunt.template.today("yyyy-mm-dd") %> - <%= commenthash.value %>', // Comment text template
      banner: false // Can be true, false, a string or a function that returns a template/boolean. Function retrieves some metadata.
