grunt-runner

Build your project using Grunt from Atom.

How to use

Set a path to your local grunt-cli in the settings (may not be necessary).
Open a project that has a Gruntfile.js in the root.
Open the task list (ctrl-alt-g) and choose a task to run, or input a new one.
The output from the grunt task will be shown in bottom toolbar. Toggle the log with ctrl-alt-t, toggle the entire toolbar with ctrl-alt-shift-t. The toolbar will appear automatically if Grunt Runner was able to find and parse a Gruntfile, otherwise you can toggle it on yourself.
If your task doesn't end automatically (e.g. watches files for changes) you can force it stop from the toolbar or by pressing ctrl-alt-shift-g.

Install Grunt Runner package using the command line

apm install grunt-runner

Or install it from the Atom Package Manager.

The Gruntfile must be in the root of your project directory to successfully get the available tasks. Additionally, all grunt commands will be called in the root directory.
Tasks added to a Gruntfile will not be automatically added until the project is reloaded or the page gets refreshed. They will still be callable from from the toolbar.
Currently hard to add tasks that prefix another task. For example, if you have a task in the task list called develop, it is impossible to add or call a task called dev
