uv-dynamic-versioning 0.4.1

Dynamic versioning based on VCS tags for uv/hatch project

uv-dynamic-versioning

poetry-dynamic-versioning influenced dynamic versioning tool for uv/hatch, powered by dunamai.

Installation

Update or add build-system and tool.hatch.version in your pyproject.toml to use uv-dynamic-versioning.

[build-system]
requires = ["hatchling", "uv-dynamic-versioning"]
build-backend = "hatchling.build"

[tool.hatch.version]
source = "uv-dynamic-versioning"

Also remove version in project and set dynamic (dynamic = ["version"]).

Before

[project]
name = "..."
version = "0.1.0"

After

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

Configuration

[!NOTE]

• Configuration is almost same to poetry-dynamic-versioning. But format-jinja, format-jinja-imports are not supported.
• The following descriptions are excerpts from poetry-dynamic-versioning.

In your pyproject.toml, you may configure the following options:

• [tool.uv-dynamic-versioning]: General options.

  • vcs (string, default: any): This is the version control system to check for a version. One of: any, git, mercurial, darcs, bazaar, subversion, fossil, pijul.

  • metadata (boolean, default: unset): If true, include the commit hash in the version, and also include a dirty flag if dirty is true. If unset, metadata will only be included if you are on a commit without a version tag. This is ignored when format or format-jinja is used.

  • tagged-metadata (boolean, default: false): If true, include any tagged metadata discovered as the first part of the metadata segment. Has no effect when metadata is set to false. This is ignored when format or format-jinja is used.

  • dirty (boolean, default: false): If true, include a dirty flag in the metadata, indicating whether there are any uncommitted changes. Has no effect when metadata is set to false. This is ignored when format or format-jinja is used.

  • pattern (string): This is a regular expression which will be used to find a tag representing a version. When this is unset, Dunamai's default pattern is used.

    There must be a capture group named base with the main part of the version. Optionally, it may contain another two groups named stage and revision for prereleases, and it may contain a group named tagged_metadata to be used with the tagged-metadata option. There may also be a group named epoch for the PEP 440 concept.

    If the base group is not included, then this will be interpreted as a named preset from the Dunamai Pattern class. This includes: default, default-unprefixed (makes the v prefix optional).

    You can check the default for your installed version of Dunamai by running this command:

    poetry run python -c "import dunamai; print(dunamai.Pattern.Default.regex())"
    

    Remember that backslashes must be escaped in the TOML file.

    # Regular expression:
    pattern = '(?P<base>\d+\.\d+\.\d+)'
    # Named preset:
    pattern = "default-unprefixed"
    

  • pattern-prefix (string): This will be inserted after the pattern's start anchor (^). For example, to match tags like some-package-v1.2.3, you can keep the default pattern and set the prefix to some-package-.

  • format (string, default: unset): This defines a custom output format for the version. Available substitutions:

    • {base}
    • {stage}
    • {revision}
    • {distance}
    • {commit}
    • {dirty}
    • {tagged_metadata}
    • {branch}
    • {branch_escaped} which omits any non-letter/number characters
    • {timestamp} of the current commit, which expands to YYYYmmddHHMMSS as UTC

    Example: v{base}+{distance}.{commit}

  • style (string, default: unset): One of: pep440, semver, pvp. These are preconfigured output formats. If you set both a style and a format, then the format will be validated against the style's rules. If style is unset, the default output format will follow PEP 440, but a custom format will only be validated if style is set explicitly.

  • latest-tag (boolean, default: false): If true, then only check the latest tag for a version, rather than looking through all the tags until a suitable one is found to match the pattern.

  • bump (boolean, default: false): If true, then increment the last part of the version base by 1, unless the stage is set, in which case increment the revision by 1 or set it to a default of 2 if there was no revision. Does nothing when on a commit with a version tag.

    Example, if there have been 3 commits since the v1.3.1 tag:

    • PEP 440 with bump = false: 1.3.1.post3.dev0+28c1684
    • PEP 440 with bump = true: 1.3.2.dev3+28c1684

  • tag-branch (string, default: unset): Branch on which to find tags, if different than the current branch. This is only used for Git currently.

  • full-commit (boolean, default: false): If true, get the full commit hash instead of the short form. This is only used for Git and Mercurial.

  • strict (boolean, default: false): If true, then fail instead of falling back to 0.0.0 when there are no tags.

  • ignore-untracked (boolean, default: false): If true, ignore untracked files when determining whether the repository is dirty.

Simple example:

[tool.uv-dynamic-versioning]
vcs = "git"
style = "semver"

Environment variables

In addition to the project-specific configuration above, you can apply some global overrides via environment variables.

• UV_DYNAMIC_VERSIONING_BYPASS: Use this to bypass the VCS mechanisms and use a static version instead. The value of the environment variable will be used as the version for the active project and any path/SSH dependencies that also use the plugin. This is mainly for distro package maintainers who need to patch existing releases, without needing access to the original repository.
