Robert,

I updated the docblock in the script with installation instructions (including Allan's handy hint about STDIN).

It's basically a standalone script which TM pipes stuff into / out of with a tiny Command.

So you open a new TM document, write your regexp on the first line, write some match/replace-fodder below it, select-all and run the Command.

please let me know if you get stuck

cheers

David, Looks great....Now the stupid question. How do I use it?

Should I place this in TextMate as a snippet and then type in a line of regexp to test and run the rx_helper over it, or install this a as a command within the ruby bundle. Alternately, should I have my file open in textmate and then write my rexexp in the "filter through command" after calling rx_helper.

Thanks for the work, and the time to explain its use

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
