This is the repository that goes along with the Codemash pre-compiler 7 Languages in 7 Hours. Here, you'll find the slides, reference materials, and a starting and ending point for each language.

1. TDD
   • Write the simplest test you can to make progress
   • Write only enough code to make your test pass
   • Only refactor on green!
2. Pairing is encouraged, but you don't have to. Here's an example of ping-pong style pairing if you want to try it out:
   • You write a very simple failing test (non-compiling counts as failing)
   • You pass the keyboard to your pair to make it pass writing only enough code as is necessary
   • Your pair writes another simple failing test and passes the keyboard back
3. You may not finish the exercise in the allotted time - that's fine! You still have the rest of your life outside of this session to work on it. :)
4. Don't be a jerk.

That last one is one we can all be accountable for. This is a safe, supportive place where many of us have little to no idea what we’re doing and are there to stumble through the often uncomfortable steps of learning together.

This pre-compiler uses the prime factors kata to guide us through learning all 7 languages. Given an integer, return a list of factors for that integer that are prime numbers. For example:

To test your setup, run the tests for each exercise on the command line once you've cloned this and installed all prereqs:

• ruby - run bundle in the ruby folder, and once bundled, run rspec prime_factors_spec.rb
• clojure - run lein test from clojure/prime_factors
• haskell - run ghci PrimeFactors_Test.hs from the haskell folder and then main at the Prelude> prompt
• rust - run cargo test in the rust folder
• scala - run sbt test in the scala folder
• elixir - run mix test from elixir/prime_factors
• go - run ginkgo from the go folder

• A text editor of your choosing. I like Atom, but you do you.

• ruby 2.1.5 (https://www.ruby-lang.org/en/documentation/installation/)
• rubygems 2.2.2 (https://rubygems.org/pages/download)
• bundler 1.7.8 (http://bundler.io/)

• JDK 6
• leiningen 2.5.1 (http://leiningen.org/)

• haskell-platform 7.10.3 (https://www.haskell.org/platform/)
• os x: you will need to open xcode and agree to the license in order to run ghci

• rust 1.5.0 (https://www.rust-lang.org/downloads.html)

• scala 2.11.* (http://www.scala-lang.org/download/install.html)
• sbt 0.13.9 (http://www.scala-sbt.org/)

• elixir 1.1.1 (http://elixir-lang.org/install.html)

• go 1.5.1 (https://golang.org/doc/install)
• set the environment variable GOPATH to point at wherever you want to store go directories. in my case, on os x, that is "$HOME/code/crebma/7-languages/go"
• add $GOPATH/bin to your path variable
• go get github.com/onsi/ginkgo/ginkgo
• go get github.com/onsi/gomega
