A Scalingo buildpack for Ruby based apps (Ruby, Rack, and Rails apps). It uses Bundler for dependency management.

This buildpack requires 64-bit Linux.

This buildpack will be used if your app has a Gemfile and Gemfile.lock in the root directory. It will then use Bundler to install your dependencies.

Example Usage:
    $ ls
    Gemfile Gemfile.lock

    $ scalingo create ruby-app

    $ git push scalingo master
    ...
    -----> Ruby app detected
    -----> Installing dependencies using Bundler version 1.1.rc
           Running: bundle install --without development:test --path vendor/bundle --deployment
           Fetching gem metadata from http://rubygems.org/..
           Installing rack (1.3.5)
           Using bundler (1.1.rc)
           Your bundle is complete! It was installed into ./vendor/bundle
           Cleaning up the bundler cache.
    -----> Discovering process types
           Procfile declares types -> (none)
           Default types for Ruby  -> console, rake

The buildpack will detect your app as Ruby if it has a Gemfile and Gemfile.lock files in the root directory. It will then proceed to run bundle install after setting up the appropriate environment for ruby and Bundler.

To use this buildpack, fork it on Github. Push up changes to your fork, then create a test app with BUILDPACK_URL=<your-github-url> and push to it.

The tests on this buildpack are written in Rspec to allow the use of focused: true. Parallelization of testing is provided by https://github.com/grosser/parallel_tests this lib spins up an arbitrary number of processes and running a different test file in each process, it does not parallelize tests within a test file. To run the tests: clone the repo, then bundle install then clone the test fixtures by running:

$ bundle exec hatchet install

$ bundle exec rake spec
