# SAGE_ROOT/tox.ini: Environments for testing the Sage distribution
#

# To run a specific environment:
#
#   $ tox -e docker-fedora-31-standard
#
# This will do a complete build of the Sage distribution in a Docker container, which will take a while.
#
# To do an incremental build based on the latest build of a beta version on GitHub Actions:
#
#   $ tox -e docker-fedora-31-standard-incremental
#
# This will download a large (multi-gigabyte) Docker image from GitHub Packages (ghcr.io).
#
# Specific 'make' targets can be given as additional arguments after "--".
# For example, to only run the configuration phase:
#
#   $ tox -e docker-debian-bullseye-standard -- config.status
#
# To build a single package (and its dependencies):
#
#   $ tox -e docker-manylinux-2_24-i686-standard -- ppl
#
# It can be useful to run several of the environments in parallel. For example:
#
#   $ tox -p auto -- config.status
#
# with local squid:
#
#   $ EXTRA_DOCKER_BUILD_ARGS="--build-arg http_proxy=http://host.docker.internal:3128 --build-arg https_proxy=http://host.docker.internal:3128" tox -p auto -- config.status

    ### "docker" environments copy sources from the source tree subject to the exclusions in
    ### the file ".dockerignore".  This should work out of non-clean source trees, and all
    ### "docker" toxenvs can be run in parallel.

    ### Package factors:
    ###
    ### - minimal   # Install a minimal set of system packages that supports bootstrapping and compiling Sage.
    ### - standard  # Install all known system packages equivalent to standard packages that have spkg-configure.m4
    ### - maximal   # Install all known system packages equivalent to standard/optional packages that have spkg-configure.m4

    docker-ubuntu-trusty-toolchain-gcc_9-minimal,
    docker-debian-bullseye-standard,
    docker-fedora-34-standard,
    docker-archlinux-latest-maximal,
    docker-manylinux-2_24-i686-standard,
    docker-conda-forge-standard,

    ### "local" targets should be run from a source tree that is freshly checked out
    ### (for example, by 'git worktree add ...') or has been cleaned by 'make bdist-clean' --
    ### because they build within the source tree (because we have no VPATH support).
    ### Only one "local" target can be run at a time.
    ### However, "local" targets install in a separate prefix (SAGE_LOCAL=.tox/TOXENV/local)
    ### rather than "local/" and also place log files into .tox/TOXENV/log, where TOXENV
    ### is the name of the environment.  (The prefix can be configured by passing the
    ### environment variable PREFIX.)
    #
    # The "local-homebrew" toxenvs create an "isolated" homebrew installation (not in /usr/local).
    # (However, many configure scripts still look for stuff in /usr/local.)
    #
    # By default, it runs "make build" (after bootstrapping and configuring)
    # with SAGE_CHECK=yes and SAGE_CHECK_PACKAGES set to a good default,
    # and V=0 so that screen output is limited.
    #
    #   $ tox -e local-homebrew-macos-standard
    #
    # The value of MAKE is picked up from the environment, so you can do:
    #
    #   $ MAKE="make -j8" tox -e local-homebrew-macos-standard
    #
    # Build targets can be passed as positional arguments (separated from tox options by "--"):
    #
    #   $ tox -e local-homebrew-macos-standard -- ppl
    #   $ tox -e local-homebrew-macos-standard -- build ptest
    #
    # Also make variables can be passed as positional arguments; for example, to run the
    # test suite:
    #
    #   $ tox -e local-homebrew-macos-standard -- SAGE_CHECK=no build ptest SAGE_NUM_THREADS=4
    #
    # Or to rebuild a package with verbose output:
    #
    #   $ tox -e local-homebrew-macos-standard -- ppl-uninstall ppl V=1
    #
    # The variant "local-homebrew-macos-usrlocal" uses the global installation in /usr/local
    # instead.  It may install packages or update packages.  It will not remove packages.
    # Use at your own risk.
    #

    ###
    ### The "local-direct" toxenv passes the whole environment on to the sage build.
    ### Whatever is in PATH etc. will be used.
    ###
    #
    #   $ tox -e local-direct -- openblas
