Shoes 4 : the next version of Shoes

Hacking

*nix

1. Fork the repository and clone your fork, or

    $ git clone git://github.com/shoes/shoes4.git
   

2. Install a JDK and JRuby

    $ rvm install jruby
   

Note: Please make sure that you either install jruby-1.7.0 or higher or you set jruby to always run in 1.9 mode. This is required in order for shoes4 to work.

3. Set up your local environment

    $ cd shoes4
    $ gem install bundler && bundle install
   

4. You're ready to go!

Windows

1. Fork the repository and clone your fork, or

    C:\tmp> git clone git://github.com/shoes/shoes4.git
   

2. Install a JDK and JRuby (Windows Executable)

3. Set up your local environment

JRuby 1.7

    C:\tmp>cd shoes4
    C:\tmp\shoes4>jruby -S gem install bundler
    C:\tmp\shoes4>jruby -S bundle install

JRuby 1.6

    C:\tmp>cd shoes4
    C:\tmp\shoes4>jruby --1.9 -S gem install json -v '1.6.1'
    C:\tmp\shoes4>jruby --1.9 -S gem install bundler
    C:\tmp\shoes4>jruby --1.9 -S bundle install

4. You're ready to go!

Refer to the RubyInstaller DevKit if you are having issues building native gems. You might be forced to download and install MinGW if your system is missing GCC or make.

Running Specs

Shoes 4 is developed in a TDD style. You should be writing and running the specs :)

There are two kinds of Shoes 4 specs:

1. Integration specs: These specify the functionality of the Shoes DSL. They can be run with any compatible Shoes backend. Shoes 4 comes with a mock backend and an Swt backend that can run the integration specs.

2. Isolation specs: These specify the internal behavior of a Shoes backend, in isolation from the DSL. Shoes 4 comes with an isolation spec suite for the Swt backend.

There are rake tasks for running specs. Some examples:

$ rake spec                      # Run the whole spec suite
$ rake spec:shoes                # Run integration specs using the mock backend
$ rake spec:swt                  # Run integration specs using the Swt backend, plus isolation specs for the Swt backend
$ rake spec:swt:isolation        # Run isolation specs for the Swt backend
$ rake spec:swt:integration      # Run integration specs using the Swt backend
$ rake spec[Shape]               # Run the whole spec suite, but only for Shape
$ rake spec:shoes[Shape]         # Run integration specs for Shape using the mock backend
$ rake spec:swt[Shape]           # Run integration and isolation specs for Shape, using the Swt backend
$ rake spec:swt:isolation[Shape] # Run isolation specs for Shape using the Swt backend

Note: For Windows, C:\tmp\shoes4>jruby --1.9 -S rake spec

Running a Shoes App

Shoes 4 comes with a command-line app runner. Just pass it the filename of your Shoes app.

$ bin/swt-shoooes samples/simple-sound.rb

Note: For Windows, C:\tmp\shoes4>bin\swt-shoooes samples\simple-sound.rb

Packaging a Shoes App

Packaging is just a baby, so be gentle.

If this is your first time running the packager, you'll want to bundle install to pull in a couple of additional gems.

In order to package an app, you need to have the Shoes gem installed in your environment.

$ rake gem
$ gem install pkg/shoes-4.0.0.pre1

Now, you can package an app. But first, looky here:

• The packager will include everything in the directory of your shoes script and below, unless you tell it not to.
• The packager will probably not work properly if it detects a .gemspec or a Gemfile. It uses Warbler, which always looks for those files. If you run the specs, you may notice some warnings like this:

warning: Bundler path' components are not currently supported. The shoes-4.0.0.pre1' component was not bundled. Your application may fail to boot!

That's Warbler talking. Actually, we sneak the Shoes gem in anyway, but don't tell.

Okay, now for real. The simplest thing is to put your script in a directory by itself and then

$ bin/shoes -p swt:app path/to/directory-of/your-shoes-app.rb

You'll find your app at path/to/directory-of/pkg/Shoes App.app.

If you want more control (like you want to name your app something besides "Shoes App", or you don't want to include all of those files we talked about before), make an app.yaml file. See the example for more details. When you have an app.yaml file right next to your script, you have three options:

$ bin/shoes -p swt:app path/to/directory-of/your-shoes-app.rb
$ bin/shoes -p swt:app path/to/directory-of/app.yaml
$ bin/shoes -p swt:app path/to/directory-of

The packager will find your instructions using any of those commands. Again, you'll find your app in the pkg directory inside your project's directory. Find out more at bin/shoes --help.

Oh, and you can also just run your Shoes apps with bin/shoes.

Want to contribute?

That's awesome, thank you!

You can go ahead an try to fix one of our issues.

Also there is a list of samples that already work at samples/README, along with all the other samples. You can try to get a new sample to run.

With all you do, please make sure to write specs as Shoes 4 is developed TDD-style (see the Running Specs section above). So make sure that you don't break any tests :-)

If you feel unsure about testing or your implementation just open an issue or a pull request. We're happy to help you get your contribution ready to be merged in order to help build Shoes 4!
