[TxMt] a regexp test script (link)

[David Lee]

Hi all

I've written a short ruby script for the purposes of checking regular  
expressions within TextMate.

http://dml.homedns.org/rx_helper.rb

It expects to be fed a regular expression on a line of its own,  
followed by any number of lines to test against. The RX can be either a  
straight match (eg ^([a-z]+):([0-9]+ ) or a substitution (eg,  
/old/new/). Cuddling /slashes/ are only required for  
/pattern/replacement/ expressions.

If you create the following action in TextMate:

echo "$TM_SELECTED_TEXT" | /path_to_script/rx_helper.rb

with input='selected text' & output='show as tooltip', you can open a  
new window, write a regexp, write some test cases for your regexp, then  
select-all and see the results in a tooltip whenever you need it (I  
have it bound to ctrl-alt-option-X).

I hope someone finds it useful. If you find any bugs / have any  
suggestions on how to improve it, please do let me know.

cheers
