What’s the simplest thing that could possibly go wrong?

String#casecmp

4 comments

As far as I can tell, this is the correct way to do case-insensitive string comparison in Ruby:

if string1.casecmp(string2) == 0
  # strings match, ignoring case
end

That’s so ugly, it almost looks like Java. Actually, it’s worse than Java, which has String#equalsIgnoreCase.

  1. We need to do that for Mojo too as .NET creates the hex digest in upper case =/

  3. This looks better to me:

    string1.downcase == string2.downcase

  4. You could use regular expressions:

    string1 =~ /^string2$/i
