Ability to reference variables across pyproject.toml

[linjer]

Is there a way to set a variable somewhere in the pyproject.toml that is used in other places of the file? Specifically, I'm interested in setting python = "3.10" in one place, and have multiple environments reference the variable. This way I can set the python version across all environments without having to update multiple strings.

I found a simple workaround for anyone who finds their way here. I defined a special environment called base where I put the python version to be shared.

[tool.hatch.envs.base]
template = "base"
python = "3.11"

[tool.hatch.envs.default]
template = "base"
# ...

[tool.hatch.envs.deploy]
template = "base"
# ...

[tool.hatch.envs.training]
template = "base"
# ...

This does not provide general variables for other uses, but this solved my original problem.

This is the way for now, thanks! It's possible that I might add the ability to reference variables from other environments but I don't know if that would add much value on top of inheritance.
