Automated tools and guides for generating 3000+ standalone C++ functions organized into a static library.
This project provides everything needed to:
- Generate thousands of standalone C++ functions
- Organize them into a compilable static library
- Validate function quality and requirements
- Build and test the complete library
Get started in 10 minutes:
# 1. Make scripts executable
chmod +x generate_project.py validate_functions.py
# 2. Generate a small test project (10 functions)
python3 generate_project.py --output ./test_project --count 10
# 3. Build and test
cd test_project
mkdir build && cd build
cmake .. && make
./FunctionLibrary_testSee QUICKSTART.md for detailed first-time setup.

Each function must meet these criteria:
- 50-100 lines of code (some can be slightly less)
- No parameters OR all parameters have default values
- Example:
int fun_algo(int n = 100, string s = "default")
- C++17 standard library only
- No third-party libraries
- No networking modules
Functions must not be optimized away:
- Include
coutstatements (side effects) - Use
volatilekeyword for results - Return values are used by caller
- Compiles successfully with C++17
- Links into static library
- No memory leaks
- No undefined behavior
Automatically creates project structure with function templates.
python3 generate_project.py --output ./my_project --count 100 --build-system cmakeOptions:
--output, -o: Output directory (default:./function_library)--count, -n: Number of functions (default: 10)--build-system, -b: Build system:cmakeormake(default:cmake)
Generates:
- Header files (.hpp)
- Implementation files (.cpp)
- FuncRunner controller class
- Build system files (CMakeLists.txt or Makefile)
- main.cpp test driver
- README and documentation
Validates functions meet all requirements.
python3 validate_functions.py ./my_project --compile --report validation.mdOptions:
project_path: Path to project directory--compile, -c: Attempt to compile each function--strict, -s: Strict validation (stricter line count)--report, -r: Generate markdown report
Checks:
- Line count (50-100 range)
- Anti-optimization measures (cout, volatile)
- No prohibited includes
- Parameters have defaults
- No common class name collisions
- Compilation success (if --compile used)

| Issue | Solution |
|---|---|
| Compilation errors | Check includes (standard library only) |
| Linker errors | Verify unique function names |
| Functions optimized away | Add cout and volatile |
| Memory leaks | Use smart pointers, check destructors |
| Build too slow | Use parallel make: make -j8 |

This project structure and tools are provided as-is for educational and development purposes.
This is a project generation tool. To improve:
- Enhance validation rules in
validate_functions.py - Add more AI prompt templates to
AI_PROMPTS.md - Improve project generator features
- Add more example functions
For issues:
- Check WORKFLOW.md troubleshooting section
- Review validation reports for specific errors
- Consult example function for reference
# 1. Generate test project
python3 generate_project.py --output ./my_test --count 10
# 2. Open AI_PROMPTS.md and copy a prompt
