So, as I'm in the process of transitioning to Bitbucket, which will eventually entail a proper website-ish thing, I'll actually be posting some more developer style stuff here.
First subject: Ruby Custom String Delimiters. This is a feature of Ruby which just shouldn't be allowed. Basically, Ruby claims it can substitute an arbitrary symbol for a string delimiter, by prefixing the delimiter with %q or %Q (depending on if you want a double or single quoted string, which are different in Ruby). Also using a symbol which has a matching closing symbol will cause the closing symbol to be the end of the string (e.g. using [ causes ] to end the string).
Got that? Well, here's some counter-intuitive stuff you have to deal with when trying to parse the damn thing, when playing around with IRB and Ruby 1.8:
- %q"Hello\n" == "Hello\n" => False (so it's insufficient to look at quotation mark to determine type of string)
- %q] does not end the string
- %q]] is a syntax error
- %q£Hello£ quits IRB
