That's find and dandy for interactive use but <br> I've found that you really want to have your regexp test cases stored<br> in a file (preferably a largish sample of the typical text that this <br> program is supposed to encounter.<p> Way back in my awk programming days I found it handy to write small <br> stubs of awk code that simply desplayed regexp matches from my test<br> case file. Actually having two test case files make sense --- one <br> that contains nothing but cases that should match and the other such<br> that there should be NO matches.<p> So, perhaps we should send the author a patch that implements these<br> features --- in the form of two buttons: <p> Test Cases: [Run] [Configure]<p> Configure would allow one to point to one or two text files (for<br> &quot;match all&quot; and &quot;match none&quot; (and optionally allow cases to be added <br> to or removed from either of them).<p> Run would just run the current regexp against all the test cases<br> and show any failures.<p> This feature would promote one of the best practices from eXtreme<br> Programming --- create test suites and harnesses before coding.<p>JimD http://lwn.net/Articles/29220/rss 2003-04-17T16:26:25+00:00 piman Python's regular expressions are much closer to Perl (and Ruby, and anything else with PCREs) than to POSIX. http://lwn.net/Articles/29105/rss 2003-04-17T03:13:37+00:00 komarek Isn't the Python regex syntax pretty close to the POSIX syntax available in C regex libraries under unix-ish systems? If so, I'd think that Kodos might be handy outside of Python, too.<p>-Paul Komarek
