FakeLua is a dialect of Lua that compiles code into native machine code at runtime using Just-In-Time (JIT) compilation, providing a streamlined language structure and improved performance.

# Features:

* Compiles with C++23

* Builds on Linux and MinGW

* Supports Lua 5.4 syntax

* Uses Flex and Bison for lexing and parsing

* Compiles to native code using GCC JIT

* Supports GDB for debugging Lua source code

# Differences from Lua:

* No global variables, only global constants

* No garbage collection (GC); uses a memory pool instead

* No coroutines, threads, userdata, or metatables

* Tables are exclusively hash tables, not array tables

* String concatenation supports all data types

* No closures, as they are slow and complex to implement

# Directory structure

* [include](./include) header file

* [src](./src) source code

* [test](./test) test code

* [benchmark](./benchmark) benchmark code

* [cmd](./cmd) command line tool

* [cmake](./cmake) cmake toolchain

# Build

### Linux

* Dependent: install gcc-13 with jit, cmake, flex, bison. install Lua for test.

* Build: 

```shell

mkdir build

cd build

cmake ..

make

```

### Mingw

* Dependent: install [MSYS2](https://www.msys2.org). install [mingw-w64-x86_64-libgccjit](https://packages.msys2.org/package/mingw-w64-x86_64-libgccjit), [mingw-w64-x86_64-lua](https://packages.msys2.org/package/mingw-w64-x86_64-lua). install CLion.

* open project with CLion, set mingw toolchains. and build.
