Compile Garry's Mod Lua into bytecode using Rust!

• Compatible with Windows and Linux
• Works with 32-bit and 64-bit branches of the game (you must compile for the correct target however)
• Thread-safe

Add to your Cargo.toml file:

[dependencies]
gluac-rs = "*"

This crate supports the parking_lot Mutex, just add the parking_lot feature flag like so:

[dependencies]
gluac-rs = { version = "*", features = ["parking_lot"] }

// A utility macro for user-friendly generation of Lua-compatible CStrings.
use gluac::lua_string;

// The instance of our bytecode compiler. This internally creates and prepares a Lua state and closes it when dropped.
let compiler: BytecodeCompiler = gluac::compiler();

// Compiling a Lua source code string
let result: Result<Vec<u8>, BytecodeError> = compiler.compile_string(lua_string!(r#"print("Hello, world!")"#));
...

// Compiling a file
let result: Result<Vec<u8>, BytecodeError> = compiler.compile_file(lua_string!(r#"path/to/file.lua"#));
...

This crate requires a few dependencies to be in the same directory as the executable.

You can find these libraries in your Garry's Mod installation, they appear to pop up in a number of different paths on different platforms and branches, so here's all the ones I know of:

• bin/
• bin/win64
• bin/linux32
• bin/linux64
• garrysmod/bin

Take care to use the correct dependencies for your target branch of the game (32-bit/64-bit)

• lua_shared.dll
• tier0.dll
• vstdlib.dll

You may also need to add the directory to the LD_LIBRARY_PATH environment variable.

• lua_shared.so
• libtier0.so
• libvstdlib.so
• libsteam_api.so (32-bit only)

I think older Garry's Mod versions have _srv suffixes in the file names for these libraries. These are also supported.
