[regex-coach] feature request: Named Groups
by Randy Gerritse 31 Aug '05

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.
