hatch-pinned-extra 0.0.3

Add a packaging extra with pinned dependencies from a lock file

hatch-pinned-extra

Hatch plugin that adds a packaging extra to the wheel metadata with pinned dependencies from uv.lock.

Usage

# pyproject.toml
[build-system]
requires = [
    "hatchling",
    "hatch-pinned-extra>=0.0.1,<0.1.0",
]
build-backend = "hatchling.build"

[tool.hatch.metadata.hooks.pinned_extra]
name = "pinned"

If your package doesn't have any optional dependencies already, you will need to mark them as dynamic:

# pyproject.toml
[project]
dynamic = [
    "optional-dependencies",
]

Enabling the Plugin

The plugin requires the HATCH_PINNED_EXTRA_ENABLE environment variable to be set to activate. This design allows you to control when pinned dependencies are included:

# Build with pinned dependencies
HATCH_PINNED_EXTRA_ENABLE=1 uv build

# Update lockfile without constraints from pinned dependencies
uv lock --upgrade

This approach solves the circular dependency issue where pinned dependencies become constraints during uv lock --upgrade, preventing actual upgrades.
