Convert Sentence to Camelcase in Ruby [duplicate]

Question

This seems like it would be ridiculously easy, but I can't find a method anywhere, to convert a sentence string/hyphenated string to camelcase.

Ex:
'this is a sentence' => 'thisIsASentence'
'my-name' => 'myName'

Seems overkill to use regex. What's the best way?

Answer 1

> s = 'this is a sentence'
 => "this is a sentence"
> s.gsub(/\s(.)/) {|e| $1.upcase}
 => "thisIsASentence"

You'd need to tweak that regexp to match on dashes in additions to spaces, but that's easy.

Pretty sure there's a regexp way to do it as well without needing to use the block form, but I didn't look it up.
