In the replacement part of
evil I can add commands like
\l to lowercase the next char and
\L to lowercase everything that follows, but I am unable to find documentation for that anywhere.
I would have expected it to be documented at https://www.gnu.org/software/emacs/manual/html_node/elisp/Syntax-of-Regexps.html but that only talks about matching, not replacing.
What I found however, is that its support seems to match this list: https://www.boost.org/doc/libs/1_44_0/libs/regex/doc/html/boost_regex/format/perl_format.html
Is there documentation on this?
