   📋 Porting plan

   pre-commit is a Python-based framework for managing pre-commit hooks. The upstream project is mature and widely used. The port is straightforward since all dependencies (check_python, libyaml) are already in zopen, and a dedicated port repository exists: zopencommunity/pre-commitport.

   Build system: Python
   Dependencies (zopen): check_python libyaml
   Not yet in zopen: None
   Start from: pyyamlport/buildenv — Python, shares both dependencies

   Steps

   1. zopen-generate with Python template and check_python, libyaml as dependencies → verify: buildenv uses underscores, not hyphens
   2. Adapt upstream setup.py/pyproject.toml for z/OS if needed
   3. Build and test with z/OS Python (check_python)
   4. Add z/OS-specific patches only after a successful build
   5. Add coreutils if make install fails due to system install
   6. Document any z/OS-specific changes

   Watch out for:

   • Use check_python in ZOPEN_STABLE_DEPS
   • Only use underscores in buildenv variable names
   • Reference dependencies as ${<DEP>_HOME}
   • Guard z/OS changes with #ifdef __MVS__
   • Patch only after confirming a working build
