Tales of the Ruby Grimoire


The council of 3.0 had been called, and Scarlet was readying to join them to discuss the future of the land of Ruby. With her was her student, Red, carrying out his latest lesson.

"Now be sure to finish the remaining problems by the time I return, Red. I expect I'll have many fun things to tell you of when I return." said Scarlet.

Red nodded, still writing away on his scrolls, but as Scarlet exited the castle a sly sort of grin grew on his face.

View ruby_tricks.rb
# A few fun tricks right quick. Note that more tricks like this are over at:
# I'll probably condense this into a blog post later, but for now we'll have our fun.
# 1 - "Pattern Matching" with case
# We make a new lambda named M for brevity. Because it can be called with `[]` it
# looks quite natural in flow with a case statement.
