Luja (lou-yah) is a Lua virtual machine written in the excellent Jakt programming language.
It cannot currently interpret .lua files directly, they must first be translated to Lua bytecode using luac <input file>, which will yield a Lua bytecode file. This can be run with luja luac.out.
Luja can be built on Linux using:
> jakt src/main.jakt -I <path to Jakt runtime> -o luja
On Windows:
> jakt src\main.jakt -I <path to Jakt runtime> -o luja.exe
At the time of writing this, there is a compiler bug in Jakt that may require you to pass -I .\src to the compiler on Windows.
Luja cannot read Lua scripts directly and probably won't for a little while. I plan to implement this eventually. I have never written a Lua parser before, but I hope that this can be my first time.
This project is the first thing I have ever built using Jakt, and so is more of a learning tool for me than something I want to turn into a polished product.
