$(COPYRIGHT)
luax is a Lua interpreter and REPL based on Lua 5.4
augmented with some useful packages.
luax can also produce standalone scripts from Lua scripts.
luax runs on several platforms with no dependency:
- Linux (x86_64, aarch64)
- MacOS (x86_64, aarch64)
- Windows (x86_64, aarch64)
luax can "compile" scripts executable on all supported platforms
(LuaX must be installed on the target environment).

$(title "LuaX bang file usage")
The LuaX bang file can be given options to customize the LuaX compilation.
Without any options, LuaX:
- is compiled with gcc
- is optimized for size
- is not a cross-compiler
- does not use optional modules (lz4, luasocket, luasec)
- does not use OpenSSL
$(title "Compiler")
bang -- gcc Compile LuaX with gcc (default)
bang -- clang Compile LuaX with clang
bang -- zig Compile LuaX with Zig
$(title "Compilation mode")
bang -- fast Code optimized for speed
bang -- small Code optimized for size (default)
bang -- debug Compiled with debug informations and no optimization
bang -- san Compiled with ASan and UBSan (implies clang)
bang -- lax Disable strict compilation options
bang -- strip Remove debug information from precompiled bytecode
bang -- lto Enable LTO optimizations
bang -- nolto Disable LTO optimizations (default)
$(title "Optional features")
bang -- lz4 Add LZ4 support
bang -- nolz4 No LZ4 support (default)
bang -- socket Add socket support via luasocket
bang -- nosocket No socket support via luasocket (default)
bang -- ssl Add SSL support via LuaSec and OpenSSL
bang -- nossl No SSL support via LuaSec and OpenSSL (default)
bang -- cross Generate cross-compilers (implies compilation with zig)
bang -- nocross Do not generate cross-compilers (default)
Zig is downloaded by the ninja file.
gcc and clang must be already installed.
