grunt-git-ref-changed-files

Detects which files have changed between two git refs.

Getting Started

If you haven't used grunt before, be sure to check out the Getting Started guide.

From the same directory as your project's Gruntfile and package.json, install this plugin with the following command:

npm install grunt-git-ref-changed-files

Once that's done, add this line to your project's Gruntfile:

grunt.loadNpmTasks('grunt-git-ref-changed-files');

Overview

Inside your Gruntfile.js file add a section named refChangedFiles. This section specifies the options to detect which files have changed between two refs (from/to) and a regular expression to filter them.

How it works

It will query which files have changed since the specified from/to parameter using git by running:

git log {ref}..{ref} --name-only --pretty=format:

Finally it will filter the changed files by applying the regexp option to every item. The result of the filtered files changed will be stored in a grunt config item called refChangedFiles.

Config Example

Example to detect if static files where modified since v.100 tag:

refChangedFiles: {
    dist: {
        options: {
            from: 'v.100', // optional: default is HEAD^
            to: 'HEAD', // optional: default is HEAD
            regexp: /public\/lib\/js/, // optional: default is /.*/
        },
        src: 'repoFolder'
    }
}

Then you can access to the filtered changed files using:

grunt.config.get('refChangedFiles');
