Ceedling is a build system for C projects that is something of an extension around Ruby’s Rake (make-ish) build system. Ceedling also makes TDD (Test-Driven Development) in C a breeze by integrating CMock, Unity, and CException -- three other awesome open-source projects you can’t live without if you're creating awesomeness in the C language. Ceedling is also extensible with a handy plugin mechanism.

Documentation and license info exists in the repo in docs/

First make sure Ruby is installed on your system (if it's not already). Then, from a command prompt:

> gem install ceedling

> git clone --recursive https://github.com/throwtheswitch/ceedling.git
> cd ceedling
> bundle install # Ensures you have all RubyGems needed
> bundle exec rake # Run all CMock library tests

If bundler isn't installed on your system or you run into problems, you might have to install it:

> sudo gem install bundler

Ceedling can deploy all of its guts into a folder. This allows it to be used without having to worry about external dependencies. You don't have to worry about Ceedling changing for this particular project just because you updated your gems.

ceedling new YourNewProjectName

This will install all of Unity, CMock, and Ceedling into a new folder named YourNewProjectName. It will also create a simple directory structure for you with src and test folders. SCORE! It's also creates a simple rakefile and project.yml file that you can tweak to your own needs.

It'll also include documentation for all of these tools, unless you specify --nodocs at when you issue the command above... then it skips that step for you.

Ceedling can also be used as a gem. By installing it this way, you can automatically update to the latest version of Ceedling, Unity, and CMock just by running an update on your gems. Use this if you are only running one project OR if you feel you want to keep all your projects up to date.

ceedling new YourNewProjectName --as_gem

This creates a new folder named YourNewProjectName. Inside it will be your shiny new project file, rakefile, and a couple of src and test directories to get you started. You can then tweak all of those things to your heart's content.
