Automatic reflection data generator for ApexGameEngine

Apex-Reflect-Tool

Automated reflection data generator for Apex Game Engine based on clang LibTooling. The generated C++ files are intended to be used with Apex Game Engine's Reflection library.

• Currently tested only on windows, Visual Studio 19

How to Build

First run the bootstrap script to download dependencies at the proper locations.

python bootstrap.py

This will download LLVM, Clang and fmt at ./llvm, ./clang and ./clang-tools-extra/ApexReflectTool/fmt-8.1.1 respectively.

To generate the Visual Studio projects, run the following commands -

cd build
cmake_gen_projects.bat

The solution will be generated at build/LLVM.sln. Build the project ApexReflectTool found under the Clang executables group.

How to Use

By providing compilation command in command line

ApexReflectTool.exe path/to/header_file.h -- clang++ -xc++ -DAPEX_REFLECT_TOOL -Ipath/to/Reflect.h -c

By providing compilation database in compile_commands.json
