Documentation

In addition to the pychlv package, the pychlv distribution file contain the tests, the test results (on macOS only) and the complete documentation generated by Epydoc using command line: epydoc --html --no-private --no-source --name=pychlv --url=... -v pychlv.

Tests

The tests ran with Python 3.14.6, 2.7.18 and with PyPy 7.3.17 (Python 3.10.14), all with pygeodesy 26.5.26 and on macOS 26.5.2 Tahoe in 64-bit. The results of those tests are included in the distribution file.

Python 3.14.6 and PyPy 7.3.17 run on Apple M4 (arm64), natively. Python 2.7.18 runs on Intel (x86_64) or Intel emulation ("arm64_x86_64", see function pychlv.machine).

Test coverage has been measured with coverage 7.14.0 using Python 3.14.6. The complete coverage report in HTML and a PDF summary are included in the distribution file.

The tests also ran with Python 3.14.6 on Windows 2019Server and with Python 3.13.3 on Windows 11, both in 64-bit only.

Notes

All Python source code has been statically checked with Ruff using Python 3.13.12 and with PyChecker, PyFlakes, PyCodeStyle (formerly Pep8) and McCabe using Python 2.7.18, both in 64-bit on macOS 26.5.2 Tahoe only.
