20:59:34 <jbk> am I completely misreading regex(7), or should both of these regexes match: https://gist.github.com/jasonbking/b3cb4b2fc33e31bf6a7057176098f05f
21:05:12 <richlowe> [[:digit:]] no?
21:07:14 <richlowe> that is, `[<foo>]` is a character class, and `[:digit:]` expands to the set of characters that are digits in this locale
21:07:24 <richlowe> so `[[:digit:]]` forms a character class of those digits
21:08:09 <jbk> maybe?
21:08:26 <richlowe> I should note I'm saying this from memory, and memory of a book in the 90's that explained it really well.  Definitely not that manual page, which regardless of whether I'm right, does not explain it well
21:08:31 <richlowe> or, potentially, does not explain it
21:08:38 <jbk> hrm... ok
21:08:40 <jbk> that worked
21:09:36 <jbk> the man page though is not very clear on that
21:09:38 <jbk> at least to me
21:10:15 <jbk> that [:xxx:] is what goes inside of [] vs. being a variant of []
21:11:16 <otis> and character classes are locale aware
21:36:29 <sommerfeld> https://en.wikibooks.org/wiki/Regular_Expressions/POSIX_Basic_Regular_Expressions says "a[:digit:]b is an error: character classes must be in brackets"
22:12:29 <jbk> oh that has much better examples than the manpage
22:13:23 <jbk> i've always tended to just use [0-9] or such since that's historically worked everywhere...
