mod_invites: Refactor argument handling using util.argparse This makes it so that --admin and --role are no longer mutually exclusive, they the former is simply treated as another --role. This was likely a leftover from when only a single role was possible. It does however become unclear which should be the primary, since the order is not preserved by argparse. Bonus: Loading of modules is avoided with only the --help is shown.

-- Compatibility layer for bitwise operations

-- First try the bit32 lib
-- Lua 5.3 has it with compat enabled
-- Lua 5.2 has it by default
if _G.bit32 then
	return _G.bit32;
end

do
	-- Lua 5.3 and 5.4 would be able to use native infix operators
	local ok, bitop = pcall(require, "prosody.util.bit53")
	if ok then
		return bitop;
	end
end

error "No bit module found. See https://prosody.im/doc/depends#bitop";
