Is it possible to replace list values when extend-ing another toml file

[brki]

For example, with parent-ruff.toml:

line-length = 120

[lint]
select = ["E", "W","F"]
ignore = ["E402"]

And project-ruff.toml:

extend = "./parent-ruff.toml"

line-length = 80

[lint]
ignore = ["E501"]

I would like it if the final lint.ignore value is ["E501"].
The actual value seems to be ["E402", "E501"].

The scalar line-length value takes the value from project-ruff.toml, but the list value seems to have the values combined, like a set union.

The semantics on how values are combined depends on the setting. I don't think there's a way to unset values in the ignore list. But you can re-select the rule using extend-select = ["E402"]

"unignoring" is basically the same as "reselecting" in most cases. (The difference is there's no "go back to default", but Ruff doesn't have many default rules anyway).

This should work fine with eventual shared configs, which would"ve been my concern.
