matrix environment selection with run and env run doesn't work as expected / documented

[tobi45]

I have a matrix environment defined and want to run a script/command in a subset of all matrix based environments. For that purpose the run command has the + and - options and the env run command the -i and -x options to select a subset of all environments.

With both commands and options it is possible to select a value along one dimension/list, but not along more than one dimension/list.

Should it be possible to select/include values along multiple dimensions/lists?

Environment definition from pyproject.toml:

[tool.hatch.envs.test]
detached = true

[[tool.hatch.envs.test.matrix]]
python = ["3.8", "3.9"]
tensorflow = ["2.12.*", "2.11.*", "2.10.*", "2.9.*"]

[tool.hatch.envs.test.scripts]
test = [ "echo {env_name}" ]

My goal is e. g. to run a script/command in the environment with python 3.8 and tensorflow 2.11.*. Next are my tries with their result. Note that I included runs to show that the * in the value shouldn't be the problem.

• hatch run +tensorflow=2.11.* test:test
  • works correctly, all python versions: test.py3.8-2.11.*, test.py3.9-2.11.*
• hatch run +python=3.8 test:test
  • works correctly, all tensorflow versions
• hatch run +tensorflow=2.11.* +python=3.8 test:test and hatch run +python=3.8 +tensorflow=2.11.* test:test
  • neither python specific nor tensorflow specific, thus all python versions and all tensorflow versions
• hatch run +python=3.8,tensorflow=2.11.* test:test
  • python specific but not tensorflow specific, thus all tensorflow versions
• hatch run +tensorflow=2.11.*,python=3.8 test:test
  • tensorflow specific but not python specific, thus all python versions

Then I tried env run:

• hatch env run -i tensorflow=2.11.* -i python=3.8 test:test
  • error: Variable selection is unsupported for non-matrix environments: default
  • according to the documentation it should work: https://hatch.pypa.io/latest/cli/reference/#hatch-env-run
• hatch env run --env test -i tensorflow=2.11.* -i python=3.8 test
  • neither python specific nor tensorflow specific, thus all python versions and all tensorflow versions
• hatch env run --env test -i tensorflow=2.11.* test
  • works correctly, all python versions
• hatch env run --env test -i python=3.8 test
  • works correctly, all tensorflow versions
• hatch env run --env test -i tensorflow=2.11.* python=3.8 test
  • no error message, no output, just does nothing
• hatch env run --env test -i tensorflow=2.11.*,python=3.8 test
  • tensorflow specific but not python specific, thus all python versions

The only way I found to run scripts in exactly one matrix based environment, python 3.8 and tensorflow 2.11.*, is without the options -i or + but:

hatch env run --env test.py3.8-2.11.* test

It is unclear to me, if it shouldn't be possible and if the documentation is unclear and the command line parser has a bug or if it should be possible and there is a bug in the selection process and another one in the command line parser / option error handling.

This looks like a bug to me and should be allowed
