[regex-coach] feature request: Named Groups

Hi First of all I've gotta say, having tested all the available regex tools, your regex coach is farout the best. However, one thing has been bugging me A LOT. You don't seem to support named groups! Since this makes the output in the language I use, PHP, a lot more userfriendly (and less subject to change if you alter the expression) I use this language feature a lot: class="cell2">.*?(?P<downloads>(\d{1,3},{0,1}){0,5})\s*& .*?class="cell5">(?P<requirements>.*?)<\/td> .*?<td>Publisher:<\/td> \s*<td>(?P<publisher>.*?)<\/td> .*?<td>Limitations:<\/td> \s*<td>(?P<limitations>.*?)<\/td> .*?<td>Date.added:<\/td> \s*<td>(?P<published>.*?)<\/td> .*?<div.id="desc-body">\s*?(?P<longdesc>.*?)\s*?<\/div> like in the above example (which by the way your tool processes correctly except for the named groups, where most other tested tools failed!) in the documentation I found it says that this format: (?P<longdesc>group) ...has been adapted from python and made part of the standard... is there a reason you have not put it in the tool? and is it possible to start supporting it? that would be a BIG help!!! right now I need to strip out all names before testing and that sux0rs... it would make your tool the best out there, by a mile..!

[regex-coach] Apparent crash on complex regex in "Tree" tab
by era+regex=coach＠iki.fi 30 Aug '05

I came across your tool, and while it appears interesting, the first thing I tried it with appears to have crashed it somehow. I was trying to run a SpamAssassin rule against a message from the SpamAssassin public corpus. Both of these are publicly available from http://www.spamassassin.org but for completeness, I am also attaching them below in exactly the form I was using them. Running the regex from 20_head_tests_cf_UNRESOLVED_TEMPLATE.txt with the /m modifier against the message headers in easy_ham_00001-head.txt and clicking on the "Tree" tab causes a lot of output to be printed on standard output (cf. third attachment) and the main window to disappear after a short while. The process is still alive, consuming around 90-95% of the CPU, though not producing a lot of load (load average still well below one). I finally killed it after allowing it to run for some 10 minutes wall clock time. Incidentally, ctrl-C causes a message "Quittingregex-coach/regex-coach : Interrupted - quitting" to be printed (on standard output, not standard error, sigh), but does not kill the process. PS. Would you mind if your list was signed up for Gmane <http://www.gmane.org/>? If I go ahead and sign up the list, do you have an mbox archive handy which could be imported into Gmane? /* era */ -- If this were a real .signature, it would suck less. Well, maybe not.

That would be incorrect. I can't reproduce that, though. If I enter these strings The Regex Coach shows a match. Are you using the newest version (0.6.7)? Maybe there's some whitespace or some hidden character in either the regex or the target string? Cheers, Edi.
