Thanks for the patch!


I am opportunist here. :-) There is this old bug #25425 [1] about lua.
Since you, Alex, sent this non-trivial patch, maybe, who knows, a fix
might be possible.

Basically, the bug is about search-patch.

$ guix shell lua lua-lpeg -- lua

Before, this tweak about environment variables was possible as an ugly
workaround (detail in the bug#25425),

--8<---------------cut here---------------start------------->8---
$ guix shell -C lua lua-lpeg
[env]$ export LUA_PATH="$GUIX_ENVIRONMENT/share/lua/5.3/?.lua;$GUIX_ENVIRONMENT/share/lua/5.3/?/?.lua"
[env]$ export LUA_CPATH="$GUIX_ENVIRONMENT/lib/lua/5.3/?.so;$GUIX_ENVIRONMENT/lib/lua/5.3/?/?.so"
--8<---------------cut here---------------end--------------->8---

but now the same trick raises an error:

--8<---------------cut here---------------start------------->8---
[env]$ lua
Lua 5.4.3  Copyright (C) 1994-2021 Lua.org, PUC-Rio
> require('lpeg')

Well, I do not know if it is related to the applied patch.  Even if, it
does not appear to me a big deal. :-) My aim here is to pop this old
issue [1] and maybe shave the yak. ;-)
