-- 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; else -- Lua 5.1 may have it as a standalone module that can be installed local ok, bitop = pcall(require, "bit32") if ok then return bitop; end end do -- Lua 5.3 and 5.4 would be able to use native infix operators local ok, bitop = pcall(require, "util.bit53") if ok then return bitop; end end do -- Lastly, try the LuaJIT bitop library local ok, bitop = pcall(require, "bit") if ok then return bitop; end end error "No bit module found.
