How to set a default addition to generated pyproject.toml?

[BruceEckel]

I would like, in every pyproject.toml I create using rye, to automatically include the following lines when rye creates the file:

[tool.black]
line-length = 47

I imagine this would be part of the config file config.toml in the .rye folder, but I don't see anything about how to do it in https://rye-up.com/guide/config/.

This gives me plugin-territory vibes, but maybe others disagree. Would make sense as a scaffolding plugin, assuming a future plugin system is attainable.

Rye shall ship with the one true formatter

I think it's a question of whether formatters and linters should be given first-class status, or whether they should be plugins.

Yea the way I'd probably do it is ship ruff with the rye toolchain when it's ready and shell out to installed alternatives like black otherwise.

Here I was mainly referring to defaults for configuration.
