👨‍💻 gluac-rs

Compile Garry's Mod Lua into bytecode using Rust!

Features

• 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

Usage

Add to your Cargo.toml file:

[dependencies]
gluac-rs = "*"

parking_lot support

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

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

Example

// 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"#));
...

Dependencies

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

Where to find them

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)

Windows

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

Linux

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.
