grunt-gitnewer

Run Grunt tasks with only those source files modified since the last git commit.

It's very like grunt-newer, but for git commit.

Usage

The gitnewer task

The most common use case. If some files changed from last git commit, and exactly match with one or more task, then those tasks will run with only those files.

grunt.initConfig({
    jshint: {
        all: {
            src: ['src/**/*.js']
        }
    }
});
 
grunt.loadNpmTasks('grunt-contrib-jshint');
grunt.loadNpmTasks('grunt-gitnewer');
 
grunt.registerTask('lint', ['gitnewer:jshint:all']);

The gitnewer-prefix task

The only differece from gitnewer task is gitnewer-prefix uses prefix match, this is useful when src of task is a list of directories.

Options

branch='HEAD', diffFilter='ACM'

Internally, the following command is executed to detect changed files from some git commit:

git diff ${branch} --name-only --diff-filter=${diffFilter}

branch and diffFilter can be configured to meet your needs.
