I recently switched from Emacs and am enjoying TextMate a lot.

I had a go at writing this for you, the only problem with it is that
the cursor doesn't move, so if you've deleted a lot of whitespace you
will find the cursor in one of the following words.

#!/usr/bin/env ruby

txt = STDIN.read
if !ENV['TM_SELECTED_TEXT']
	index = ENV['TM_LINE_INDEX'].to_i
	print txt.slice(0, index).rstrip
	print " "
	print txt.slice(index, txt.length - index).lstrip
else
	print txt.gsub(/[ \t]+/, ' ')
end


Command options:
   Selected Text or Line
   Replace Selected Text
