Formatting text entry in a custom bundle

[dmv]

Hi Everyone,

I am new to textmate and just getting started creating my own bundles. I am using a entry variable such as ${3:'CustomRemoteMethodCall'} and what I would like to be able to do is format the text that is entered to all upper case. Is there an easy way to do this??

for example, user enters hello and the bundle converts this automatically to HELLO

I am looking for the code to put into the bundle

Thanks in advance for any help

Don
