Allow configuring preview features in `uv.toml` and `pyproject.toml` by EliteTK · Pull Request #18437 · astral-sh/uv

EliteTK · 2026-03-13T01:10:50Z

Summary

This is a continuation of the excellent work by @j-helland in #16452 and #17202 and closes #15767.

This PR adds preview-features to uv.toml and pyproject.toml.

This field can be set to a boolean or to a list of features.

It is intended to supersede the preview setting itself, and conflicts with it.

There's a little bit of complexity required to ensure that setting either preview or preview-features is combined at the right point, but it's also necessary to leave them split to accurately warn when a uv.toml masks a pyproject.toml in the same directory.

Additionally there's complexity involved in making things work with deny_unknown_fields and flatten (they're incompatible so require manual flattening) and also this improves error messages somewhat.

Also (supersedes) closes #16452 and (supersedes) closes #17202.

Test Plan

Tests taken from the original PR with some alterations and a bunch of additional tests.

Can you justify replacing the preview field? I think we'll have --preview forever and I'd expect preview = true to work ~forever too?

EliteTK · 2026-06-04T13:21:14Z

It's not replaced, just hidden and mutually exclusive. More context here: #16452 (comment) and even more context is on discord I believe (from that time).

Although as written, the docs still keep the preview documentation so it's not really hidden.

The "deprecated": true in the json schema might be a bit of an overreach in this regard?

I think this is fine, but let's address my comments before merging.

I think deprecating preview (with a message nudging people towards preview-features) is the right tradeoff to get people to use the new, more flexible thing without breaking them - even if we don't intend to remove the old option.

Preview features can be configured as a boolean or list of feature names in uv.toml, pyproject.toml, and PEP 723 metadata. These values participate in preview resolution alongside command-line and environment settings. Preserve the deprecated preview spelling, reject configuring both spellings in the same document, and expose the option through settings metadata and the generated schema.
