Python setuptools_scm 从 git 标签获取版本

Question

我正在使用project.toml文件来打包我的模块，我想使用

setuptools_scm

模块从git标签中提取版本。

当我运行

python setup.p y --version

命令时，它会给出此输出

0.0.1.post1.dev0

。如何仅获取

0.0.1

值并忽略

.post.dev0

值？

这是project.toml文件设置：

[build-system]
requires = ["setuptools>=46.1.0", "setuptools_scm[toml]>=5"]
build-backend = "setuptools.build_meta"

[tool.setuptools_scm]
version_scheme = "no-guess-dev"
local_scheme="no-local-version"
write_to = "src/showme/version.py"
git_describe_command = "git describe --dirty --tags --long --match v* --first-parent"

[tool.setuptools.dynamic]
version = {attr = "showme.__version__"}

输出：

 python setup.py --version
setuptools/config/pyprojecttoml.py:108: _BetaConfiguration: Support for `[tool.setuptools]` in `pyproject.toml` is still *beta*.
  warnings.warn(msg, _BetaConfiguration)
0.0.1.post1.dev0

谢谢

setuptools_scm

开箱即用生成开发和发布后版本。

要生成像

0.0.1

这样的发布版本，您可以将可调用对象传递给

use_scm_version

：

# content of setup.py

def my_version():
    from setuptools_scm.version import SEMVER_MINOR, guess_next_simple_semver, release_branch_semver_version

    def my_release_branch_semver_version(version):
        v = release_branch_semver_version(version)
        if v == version.format_next_version(guess_next_simple_semver, retain=SEMVER_MINOR):
            return version.format_next_version(guess_next_simple_semver, fmt="{guessed}", retain=SEMVER_MINOR)
        return v

    return {
        'version_scheme': my_release_branch_semver_version,
        'local_scheme': 'no-local-version',
    }


setup(use_scm_version=myversion)
