But upon further investigation, I see that is not AlwaysTheCase (LOL @ PascalCase). I always thought camelCase was lowercase for the first-most character.

Our implementation mixes this method in to String on application startup. Hope this helps someone. I’m pretty sure I’ve got this, in case anyone cares:

self.gsub!(/\W+/, ‘ ‘) # all non-word chars to spaces
self.strip!
self.underscore.split.join(“_”).camelcase(:lower)

assuming that self is a String. Our implementation mixes this method in to String on application startup.

Hope this helps someone.

Also: phrase.gsub!(/s/, '') would return nil if no substitutions were made to phrase. gsub would return the result of phrase post-gsub even if no changes were made.

I'm pretty sure Ruby methods automagically return the last thing that gets evaluated within. Oh, and I don’t think you even need the return statement.

If you’re in Rails, you can take advantage of the Inflector class and do something like this:

>> phrase = ‘my Dog hAs FlEas’
=> “my Dog hAs FlEas”
>> phrase.downcase.gsub(/\s/, ‘_’).camelize
=> “MyDogHasFleas”
