Textmate/Regex: Strip whitespace from beginning/end of file

Question

I\'m trying to add a macro/command to Textmate for some file cleanup and the last tidbit I haven\'t figured out is simply to remove blank lines from the beginning and end of a f

Answer 1

This regex will remove the whitespace at the beginning of the file

Find ^[\r\n\t ]+ and replace with (nothing).

And this one will remove the whitespace at the end

Find [\r\n\t ]+$ and replace with (nothing).

I've never used Textmate regular expressions. There can be a \s (whitespace) class you can use instead of [\r\n\t ]. Also, you might need to turn multi-line mode on, if there is one.
