Configuration to exclude/rewrite tag names?

[dbarnett]

It would be nice to be able to customize what tag names setuptools-scm considers as the version for a package, and to be able to rewrite the literal tag name to do things like strip a known prefix.

Motivation: I have a repo https://github.com/dbarnett/vim-plugin-metadata that contains both a core implementation rust package and a python interface. I've been tagging the core versions with vx.y.z and the python interface versions with py-vx.y.z, but I can't find any configuration options to hook up the python project to just the py-v* tags and ignore the others.

Currently it's necessary to set a custom describe command to consider only prefixed tags

[dbarnett]

Ah ok, like

git_describe_command = ['git', 'describe', '--dirty', '--tags', '--long', '--match', SOME_PATTERN]

?

But then I guess it's hard-coded to only work on git repos, so it would still be important to get a generalized solution to that.

And for my particular case I guess I can't rely on setuptools-scm at all unless I migrate away from maturin: PyO3/maturin#1267.

A more general tag prefix support is in the pipeline but still pre-planning
