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-changelog --save-devOnce the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-changelog');In your project's Gruntfile, add a section named changelog to the data object passed into grunt.initConfig(). The task, by default, will go through the last 7 days of commit messages, looking for issues that were closed or fixed. It will then generate a template-based changelog with those changes and write them to a destination file.
grunt.initConfig({
changelog: {
sample: {
options: {
// Task-specific options go here.
}
}
},
