Could you please provide a tested patch for 'lua' package with the changes you suggest?

Attached patch seems to work. It provides both package names that debian had in
addition to archlinux. Seems to work fine:

[root@269d701c4588 /]# pkgconf --list-all | grep lua | sort
lua-5.3 Lua - An Extensible Extension Language
lua5.3 Lua - An Extensible Extension Language
lua53 Lua - An Extensible Extension Language
lua Lua - An Extensible Extension Language

[root@269d701c4588 /]# for pkg in $(pkgconf --list-package-names | sort | grep lua); do \
> echo $pkg: $(pkgconf --libs $pkg); \
> done
lua: -llua -lm
lua-5.3: -llua -lm
lua5.3: -llua -lm
lua53: -llua -lm

Thank you for considering this :)

Your patch looks good. I just pushed lua to [testing]. Please verify that it works as expected.

I also modified lua52 and lua51 accordingly to stay consistent with 'lua' package.

Thank you for acting on this ticket :) I've tested the packages in testing and
they seem to work fine:

[root@dc472776420f lua]# cat test.c
#include <lua.h>
#include <lauxlib.h>
#include <lualib.h>

int main(void) {
lua_State *lua = luaL_newstate();
luaL_openlibs(lua);
luaL_dostring(lua, "print('" PKG_NAME ": ' .. _VERSION);");
lua_close(lua);
return 0;
}
