docs: regex library non-capture support #18900
Description
Documentation URL
https://docs.micropython.org/en/latest/library/re.html
Description
The documentation states that non-capture groups are not supported:
- non-capturing groups (
(?:...))
But at https://github.com/micropython/micropython/blob/master/lib/re1.5/compilecode.c#L92 it looks like it is supported.
int capture = re[1] != '?' || re[2] != ':';
And
import re
re.match("(?:.)","1")
returns
<match num=1>
suggesting that it works.
