FakeLua(Work in process)

FakeLua is a superset of Lua, it compiles Lua to native code at runtime.

Feature

• compile with C++23
• build on Linux && Mingw
• support Lua 5.4 grammar
• lexing and parsing by Flex && Bison
• compile to native code by GCC JIT
• support GDB Lua source code

Difference with Lua

• no global variable, only global constant
• no GC, use memory pool
• no coroutine/thread/userdata/metatable
• table are always hash table, no array table
• string concat support all type
• no closure, it's slow and complex to implement

Directory structure

• include header file
• src source code
• test test code
• benchmark benchmark code
• cmd command line tool
• cmake cmake toolchain

Build

Linux

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

mkdir build
cd build
cmake ..
make

Mingw

• Dependent: install MSYS2. install mingw-w64-x86_64-libgccjit, mingw-w64-x86_64-lua. install CLion.
• open project with CLion, set mingw toolchains. and build.
