A simple command line utility for playing ruby golf with problems defined via RSpec examples.

In ruby golf, you need to write a function that passes the provided specs in the fewest characters you can.

gem install boca-golf

git clone git://github.com/flipstone/boca-golf-problems.git

in my_solution.rb:

def sanitize(word, string)
  ... your implementation ...
end

then:

boca-golf my_solution.rb boca-golf-problems/sanitize/spec.rb

and see:

Testing my_solution.rb against specs:
  - boca-golf-problems/sanitize/spec.rb

...

Finished in 0.0007 seconds
3 examples, 0 failures

Code:
def sanitize(word, string)
  ... your implementation ...
end

Score:
<# of characters in your solution>

Go to gist.github.com and create a gist with your solution

then someone can run it with:

boca-golf <your gist url> boca-golf-problems/sanitize/spec.rb

Simply create an rspec examples file, decide on what coders should name the method, and call it!

in my_spec.rb:

describe "reverse" do
  it "reverses the string" do
    reverse("foo").should == "oof"
  end
end

then:

boca-golf solution.rb my_spec.rb

And send your problems in and we’ll give you credit in the boca-golf-problems repo!

Happy Golfing!

boca-golf runs all code from potential solutions at $SAFE = 4, so you don’t need to worry about someone’s gist wrecking your system. That being said, we are not liable for any damage caused to your system by untrusted code. Always run untrusted code at your own risk.

Problem definitions, on the other hand, are run at $SAFE = 0, so you can access any part of ruby you want within the RSpec examples you write for your problems. That also means you should be sure you trust whomever is defining the problems you’re running with boca-golf.
