Compares source & destination files before calling grunt-contrib-copy.

Currently compatible with [email protected].

Tests & much of the Gruntfile taken from grunt-contrib-copy. Extensive tests of grunt-diff-copy's actual functionality are planned.

Overview

Developed with grunt-newer integration in mind, diffCopy will only write to a destination file if its contents actually differ from the source. By filtering, "last modified" times are preserved on unchanged files, allowing grunt-newer to do its thing.

grunt diffCopy newer:myTask

The diffCopy task delegates to grunt-contrib-copy, and requires no other configuration. Just specify diffCopy instead of copy when running tasks.

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-contrib-copy --save-dev
npm install grunt-diff-copy --save-dev

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

grunt.loadNpmTasks('grunt-contrib-copy');
grunt.loadNpmTasks('grunt-diff-copy');

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, but in case you can't please use v0.3.2.

Does this actually do anything or is it vaporware?
