Good day!

Is there anywhere I can read about limitations on Hare's standard regex
implementation, besides the docs and the blog post about it?

I want to check wherever using multiple alterations is allowed.  My
program aborts when I test again the regex "(a|b|c)", with the following
error:

Abort: /usr/src/hare/stdlib/regex/regex.ha:502:4: slice or array access
out of bounds


And compiling a regex from "a|b|c" returns this error description:

Encountered ")" token without matching "("


I couldn't find anything about several alterations in a row in the POSIX
spec linked in the blog.  It seems that Hare's regex does not support
it, but I just wanted to double check in case I am doing something
wrong.

You can take a look at https://todo.sr.ht/~sircmpwn/hare?search=regex

Particularly, at #696.

Understood, thanks!

Hi, sorry, this is something that I never got around to implementing.

It should be relatively easy, so if you, or anyone else, is looking for
a quick thing to add to regex::, this would be a good candidate. I'm
always available to help in #hare if you have any questions.

Otherwise, just wait and I or someone else will do it eventually.

Regex is an interesting topic!  I'll try to contribute it once I get
better at the language.
