Transforming Ruby's hash rocket to the new syntax
When I work in projects that started before Ruby 1.9, I don't like the mix of the old hash rocket style hashes, and the new syntax.
If you want to transform the old style to the new one, this simple regex will save you some time. Just use the following string in your "Find" or "Find in Project" prompt in Textmate.
If Vim is your editor of choice, just change
This will transform all hashes from the old format to the new where possible.
The regex uses only lowercase letters, so that it doesn't find namespaced classes as the key. Also, uppercase letters in symbols are pretty rare (but allowed).
