Regexes behave differently on different OSes #9

Open frasertweedale opened 5 years ago

frasertweedale commented 5 years ago

Describe the bug Regex matching can behave differently on different OSes. This basically comes down to how the system regex(3) library behaves. e.g. on GNU+Linux (glibc), backslash character classes (e.g. \s for whitespace, \w for alnum + underscore) work fine, but they are not recognised on FreeBSD and you are restricted to POSIX definitions (e.g. [[:alpha:]]).

Expected behavior We need to decide on this - whether we want to normalise the behaviour across OSes by switching regex library to something that behaves consistently, or whether we leave it as a caveat and simply document it clearly.

Urgh, hitting this hard now, trying to test purebred on FreeBSD.
