• setuptools-scm is cool

• Wanted even more control?
• Wanted to inject your own helpers?

Example: pyproject.toml

[build-system]
requires = ["scikit-build-core"]
build-backend = "scikit_build_core.build"

[project]
name = "mypackage"
dynamic = ["version"]

[[tool.dynamic-metadata]]
provider = "scikit_build_core.metadata.setuptools_scm"

[tool.setuptools_scm]

You can chain them

[project]
name = "mypackage"
dynamic = ["version", "dependencies"]

[[tool.dynamic-metadata]]
provider = "scikit_build_core.metadata.setuptools_scm"

[[tool.dynamic-metadata]]
provider = "scikit_build_core.metadata.template"
field = "dependencies"
result = ["mypackage-core == {project[version]}"]

[tool.setuptools_scm]

There are many built-ins

[project]
name = "mypackage"
dynamic = ["dependencies"]

[[tool.dynamic-metadata]]
provider = "dynamic_metadata.pin_installed"
packages = ["torch==x.x.*"]

And you can write your own

[project]
name = "mypackage"
dynamic = ["version"]

[[tool.dynamic-metadata]]
provider = {path = "helpers/plugins", module = "my_plugin"}

def dynamic_metadata(
    settings: Mapping[str, Any],
    project: Mapping[str, Any],
) -> dict[str, Any]:
    return {"version": "1.2.3"}

Caveats

• It is only implemented in scikit-build-core right now
• Not even as scikit-build-core plugin
