8th Light Blog: Unrubify

Unrubify

Often times while writing meta programming code, I am using the eval function and doing manipulation on method/class/variable names. Today I needed to unrubify a name. I haven’t seen this done regularly, and unfortunately there is no fun rails method to do it (there is one for rubifying a string). So, here is my attempt at it, for anyone trying to solve the same problem.

def unrubify(sentence)  
  sentence.capitalize!
  sentence.gsub!(/_(.)/) { $1.upcase }
  return sentence 
end

Any suggestions on improvements please let me know!

Thank you!!! I thought it should be there somewhere, but couldn’t find it.
