hi, possible modus operandi of this code in the sinatra : str.squish.downcase.tr(" ","_")

It looks like it's attempting to underscorize the string. squish trims whitespace from the ends of the string, and replaces all multiple whitespace characters with a single one. downcase will make the string lowercase. tr will replace the character " " with the character "_". This isn't a great implementation of underscorizing, however, because it won't remove characters that aren't a-zA-Z, if that was the intention.
