So Michael Ferante talked me into trying the daily routine of a Code Kata. I was looking for two things: to learn something, and perhaps to find a programming problem suitable for a pairing exercise.
I did learn some things about Ruby: String#each_char, Heredocs (and that they can't be embedded in a single-statement Hash), and the syntax for up-to-but-not-including in ranges.
What I've found is that after three attempts I've incorporated a couple of good ideas, but I'm not going to arrive at a better solution. Does that mean I've picked too simple a problem?
My problem is also bad as a pairing exercise. I only arrive at two tests with the last test resulting in having to write the majority of the code. That would have for very dull ping-pong pairing. Again, did I pick the wrong problem?
Here's my code kata repo.
The exercise is to take a number and print it using this font - excerpt:
.d8888b. d888 .d8888b. .d8888b. ... d88P Y88bd8888 d88P Y88bd88P Y88b ... 888 888 888 888 .d88P ... 888 888 888 .d88P 8888" ... 888 888 888 .od888P" "Y8b. ... 888 888 888 d88P" 888 888 ... Y88b d88P 888 888" Y88b d88P ... "Y8888P" 8888888888888888 "Y8888P" ...Edit: For a tougher challenge, try this font: (note that the space is used more aggressively -- compare 4 vs 45 and 1 vs 01)
