Default env scripts listed by hatch env show as being avilable to all environments (standalone and matrices). Is that correct?

[doolio]

The default pyproject.toml generated by hatch new contains the following tables:

[tool.hatch.envs.default.scripts]
test = "pytest {args:tests}"
test-cov = "coverage run -m pytest {args:tests}"
cov-report = [
  "- coverage combine",
  "coverage report",
]
cov = [
  "test-cov",
  "cov-report",
]

[tool.hatch.envs.types.scripts]
check = "mypy --install-types --non-interactive {args:src/hatch_demo tests}"

But hatch env show suggests all default scripts listed for all environments. Is that expected? I thought default was just the name given to an initial environment if none is specified. Does it also infer any env.default settings apply to all environments?

$ hatch env show

Yes. default is both the environment selected when you don't name one and the default template for other environments. Scripts defined in [tool.hatch.envs.default.scripts] therefore appear in types and the matrix environments unless you disable inheritance. I checked this with Hatch 1.18.1: a types environment with its own check script also listed the hello script from default in hatch env show.

For a types environment without inherited scripts, set its template to itself:

[tool.hatch.envs.types]
template = "types"

Hatch's environment inheritance docs document this self-referential template setting.
