# CI test image for pyWebLayout
# Build: docker build -f Dockerfile.ci -t gitea.tourolle.paris/dtourolle/pyweblayout-ci:latest .
# Push:  docker push gitea.tourolle.paris/dtourolle/pyweblayout-ci:latest
#
# pyWebLayout is a library, so CI tests every interpreter pyproject.toml claims
# to support rather than just one. All four are in this image and the workflow
# matrix picks one per job; dependencies are pre-installed into each, so a CI
# run downloads nothing.

# One venv per interpreter at a predictable path, /opt/py<version>. Ubuntu marks
# its system Python externally-managed, so installing into venvs sidesteps that
# without --break-system-packages, and keeps the four dependency sets isolated.
#
# The package list is written once so versions cannot drift between
# interpreters. It mirrors pyproject.toml's runtime deps plus the test and dev
# extras; keep the two in step.
#
# Deliberately NOT installed: pyWebLayout itself. The workflow installs the
# checkout with --no-deps, so a job always tests the code under review.
#
# setuptools is pinned below 81 because that release dropped pkg_resources,
# which coverage-badge still imports at startup. Without the pin the badge step
# dies with ModuleNotFoundError. Revisit when coverage-badge stops using it.
