in reply to About \d \w and \s

Personally, I've avoided relying on unicode/charset semantics with regular expressions. Most of the input I deal with is either Latin-1 or some other "near IBM-ASCII" single byte encoding, and so is my source code. I've made my regular expressions lenient in the sense that I use dots where I expect umlauts.

Of course, if I were more strict about the encodings of my input data, or Perl were more smart about guessing the encoding of my input data (which is hard without carrying a dictionary of likenesses), I could write my source code and my regular expressions in unicode, and then it would be cool if \w would use the unicode semantics.

I have no opinion on \d, as German has only 0-9 as digits anyway, and my input data also.

    I believe that /u would provide sane matching for German or other latin-1 languages as it would make perl match according to the unicode rules even when the string/pattern weren't themselves unicode.

[stevieb]: cover it all. Awesome thing is that you can dispatch ANY distribution to it (and include all revdeps if desired), and it works all the same as if I'm just testing the RPI code itself
[stevieb]: I'm rather pleased with myself and everything I've leared along this arduous and sometimes frustrating path
[stevieb]: Just need to implement an email plugin or something so I can get alerted remotely if the status of a build has changed from the last run
[stevieb]: Because of the extreme complexity of the testing code itself, I implemented extensive logging so I can troubleshoot much easier by setting a high debug level.
[stevieb]: if you're interested in the test/build backend, have a look at Test::BrewBuild.
