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

No problem here using ruby 1.8.2 (2004-12-25) [powerpc-darwin7.7.0] in /usr/local/bin/ruby

It must be the version then... Maybe Tiger will update Ruby for me. :)

I'll test against the stock install when I get home. Shouldn't be too hard to get it playing nice with both; then I can submit it to svn :)

Great, just commit over the copy I put in the RegularExpressions.tmbundle...

Very nice. Thank you for the bundle. Robert

I've written an alternative version of the regular expression checker. It relies heavily on a script I found on the web by Aristotle at perlmonks.org (cited in the code).

I've checked it into the svn repository. There's also a version of the Ruby script that produces a tooltip (though I can't get that to work on my computer yet). They live at http://macromates.com/svn/Bundles/trunk/RegularExpressions.tmbundle/

The way this alternative works is you copy the regexp to the clipboard, then highlight the text you want to check. Then it produces HTML output which color codes each subcapture.

There might be a nicer way to grab the regexp, like maybe using Cocoadialog, but I just wanted to get this out there.

best wishes, Eric
