versioningit

• Drop support for Python 3.7
• Bugfix: When using versioningit with Hatch, don't run the onbuild step for editable builds

• Correctly mark a certain test as requiring Mercurial

• When git describe fails to retrieve a tag, the resulting log/error message now includes all options passed to the command (based on contribution by @jenshnielsen)
• When hg log fails to retrieve a tag, the resulting log/error message now includes the tag pattern passed to latesttag(), if any

• Migrated from setuptools to hatch
• Support using the onbuild step with Hatch
• Breaking: The build_dir argument passed to Versioningit.do_onbuild() and onbuild method callables has been changed to an OnbuildFileProvider ABC

• Always read .hg_archival.txt files using UTF-8 encoding
• Added support for using versioningit with Hatch

• Raise a ConfigError if the selected tool.versioningit.format field is not a string
• Update tests for pydantic 2.0
• Update tests for Python 3.12
• Support Python 3.12

• The custom setuptools command classes can now be imported directly from the versioningit.cmdclass module as an alternative to calling get_cmdclasses()

• Drop support for Python 3.6
• Support Python 3.11
• Use tomllib on Python 3.11

• Don't run the onbuild step under setuptools' upcoming PEP 660 editable mode (contributed by @abravalheri)

• The {version} placeholder in the "basic" format step has been renamed to {base_version}. The old name remains usable, but is deprecated.
  • Breaking: The version argument passed to Versioningit.do_format() and format method callables has been renamed to base_version.
• A {version_tuple} field, along with the fields available in the format step, is now available for use in templates in the write and onbuild steps.
  • New step and subtable: "template-fields"
  • Breaking: The version arguments passed to Versioningit.do_write(), Versioningit.do_onbuild(), run_onbuild(), and write & onbuild method callables have been replaced with template_fields arguments
  • Added a get_template_fields_from_distribution() function for use by callers of run_onbuild()
• Versioningit.get_version() now takes optional write and fallback arguments
• The onbuild step is no longer run when building from an sdist; the configuration therefore no longer needs to be idempotent
• Drop setuptools runtime dependency
  • setuptools is only needed for get_cmdclasses(), which should only be called in an environment where setuptools is already installed.
• Prevent log messages from being printed twice under recent versions of setuptools
• Values supplied for the require-match parameters of the tag2version and onbuild steps must now actually be booleans; previously, values of any type were accepted and were converted to booleans.
• Added a Versioningit.run() method that returns a structure containing all intermediate & final values
• "git" method: {author_date} and {committer_date} are no longer "clamped" to less than or equal to {build_date}. This undocumented behavior was based on a misinterpretation of the SOURCE_DATE_EPOCH spec, and was even applied when SOURCE_DATE_EPOCH was not set.
• When resolving entry points, if multiple entry points with the given group & name are found, error instead of using the first one returned

• Backport "Don't run the onbuild step under setuptools' upcoming PEP 660 editable mode" from v2.0.1 (contributed by @abravalheri)

• Do not import setuptools unless needed (contributed by @jenshnielsen)

• Added custom setuptools commands for inserting the project version into a source file at build time
  • New step and subtable: "onbuild"
  • New public get_cmdclasses() and run_onbuild() functions
• Moved documentation from the README to a Read the Docs site
  • Established external documentation for the public library API
• When falling back to using tool.versioningit.default-version, emit a warning if the version is not PEP 440-compliant.
• The versioningit command now honors the VERSIONINGIT_LOG_LEVEL environment variable

• Changes to custom methods:
  • The signatures of the method functions have changed; user-supplied parameters are now passed as a single params: Dict[str, Any] argument instead of as keyword arguments.
  • User-supplied parameters with the same names as step-specific method arguments are no longer discarded.
• Changes to the "git-archive" method:
  • Lightweight tags are now ignored (by default, but see below) when installing from a repository in order to match the behavior of the %(describe) format placeholder.
  • The "match" and "exclude" settings are now parsed from the describe-subst parameter, which is now required, and the old match and exclude parameters are now ignored.
  • Git 2.35's "tags" option for honoring lightweight tags is now recognized.
  • Added a dedicated error message when an invalid %(describe) placeholder is "expanded" into itself in an archive
• The file parameter to the "basic" write method is now required when the [tool.versioningit.write] table is present. If you don't want to write the version to a file, omit the table entirely.
• Library API:
  • Config is no longer exported; it should now be considered private.
  • Merged Versioningit.from_config() functionality into Versioningit.from_project_dir()
  • Renamed Versioningit.from_config_obj() to Versioningit.from_config(); it should now be considered private

• Git 1.8.0 is now the minimum required version for the git methods, and this is documented. (Previously, the undocumented minimum version was Git 1.8.5.)
• Document the minimum supported Mercurial version as 5.2.

• Call importlib.metadata.entry_points() only once and reuse the result for a speedup (contributed by @jenshnielsen)

• Support Python 3.10
• Support tomli 2.0

• Gave the CLI interface an -n/--next-version option for showing a project's next release version
• Added a get_next_version() function
• Added a mention to the README of the existence of exported functionality other than get_version()
• Renamed the individual step-calling methods of Versioningit to have names of the form do_$STEP()

• Update for tomli 1.2.0

• The log messages displayed for unknown parameters are now at WARNING level instead of INFO and include suggestions for what you might have meant
• "git" vcs method: default-tag will now be honored if the git describe command fails (which generally only happens in a repository without any commits)
• Added an experimental "git-archive" method for determining a version when installing from a Git archive
• Project directories under .git/ are no longer considered to be under version control
• Project directories inside Git working directories that are not themselves tracked by Git are no longer considered to be under version control
• Support added for installing from Mercurial repositories & archives

• Add more logging messages
• Changed default version formats to something that doesn't use {next_version}
• "basic" tag2version method:
  • If regex is given and it does not contain a group named "version," the entire text matched by the regex will be used as the version
  • Added a require-match parameter for erroring if the regex does not match
• "basic" write method: encoding now defaults to UTF-8
• New next-version methods: "minor-release", "smallest-release", and "null"
• Replaced entry-points dependency with importlib-metadata
• Added tool.versioningit.default-version for setting the version to use if an error occurs
• When building a project from a shallow clone or in a non-sdist directory without VCS information, display an informative error message.
