IPRUG Ruby Golf 2015

IPRUG, 14 April 2015

Time for another Ruby golf challenge – can you pare your code down to fewer characters than everyone else?

There will be nine "holes" to complete. I'll provide the tests to describe them on the night, to stop anyone getting a head start. And because I haven't written them yet.

The winner is whoever gets the lowest total score for all nine, or if no-one finishes then the lowest total for the furthest hole (if that makes sense). No prizes I'm afraid, apart from the admiration of your peers.

Requirements

Ruby 2.2 (so everyone's on a level playing field in terms of language features).

Setup

Before you turn up (to avoid having to download everything on the night over dodgy wifi):

git clone https://github.com/kerryb/iprug-rubygolf-2015.git
cd iprug-rubygolf-2015
gem install bundler
bundle

You'll probably want to grab an offline copy of the Ruby API docs too.

Testing

Run rake, and you should see something like this:

$ bundle exec rake
.........

Rules

  • No editing of any file apart from lib/golf.rb
  • All code must go in the methods that are already there (hole_1 etc)
  • No extra classes or methds, evaluation of other files or any other creative cheating
  • The def ... line and the final end of each method don't count towards the score
  • Whitespace does count, apart from newlines and indentation
