regular expressions would be mor or less the same in other langauges, so no difference here.

Similarily, the (?<!\/) is a "A zero-width negative look-behind assertion" So the pattern matches Error or error, but only if that [Ee]rror is not after a / and not before a . > and the \b stands for "boundary" (alphanum on the left and !alphanum on the > right or the other way around), so obviously both, the tick and the slash, > are !alphanum (as is the colon, which should still match)... Nah, you'r tricking yourself again. \b ist a change of \w to \W (not just alphanum, but also _ and some additional unicode characters) or the other way round, as you wrote yourself. But a line like foo/Error.something would happily match \bError\b - as the / marks a switch - but it should *not* match. > So maybe the easiest would be to add a "and !(A or B)" to the line to > invalidate a false positive match? No, see my comment abve about you not looking at the whole file. There are a bunch of whitelist lines in there, lines that matche the overall error-marking regexes, that should be *ignore*d (hint, hint :-))) and not counted as errors. ciao Christian _______________________________________________ LibreOffice mailing list LibreOffice@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/libreoffice
