python-alpm

Python bindings for the Arch Linux Package Management (ALPM) project.

We are currently awaiting decision from PyPI maintainers to allow us to publish this package under the name alpm. Until then, we are using the name python-alpm. You can view the support ticket here.

Documentation

Latest documentation is available at https://alpm.archlinux.page/pdoc.

Installation

pip install python-alpm

Examples

Validating and comparing versions

>>> from alpm.alpm_types import PackageVersion, PackageRelease, FullVersion, SchemaVersion

>>> full_version = FullVersion(pkgver=PackageVersion('0.1.0alpha'), pkgrel=PackageRelease(minor=1))
>>> full_version
FullVersion(pkgver=PackageVersion('0.1.0alpha'), pkgrel=PackageRelease(major=0, minor=1))

>>> PackageVersion('1.0.1') > full_version.pkgver
True

>>> version_one = SchemaVersion.from_str('1.0.0')
>>> version_one
SchemaVersion(major=1, minor=0, patch=0, pre='', build='')

>>> version_one == SchemaVersion(major=1)
True

Parsing .SRCINFO

>>> from alpm.alpm_srcinfo import SourceInfoV1
>>> from alpm.alpm_types import Architecture

>>> srcinfo = SourceInfoV1.from_file("../alpm-srcinfo/tests/correct/all_overrides.srcinfo")

>>> srcinfo.base
PackageBase(name='example', version=FullVersion(pkgver=PackageVersion('0.1.0'), pkgrel=PackageRelease(major=1), epoch=1))

>>> srcinfo.base.architectures
Architectures([Architecture('x86_64'), Architecture('aarch64')])

>>> srcinfo.packages
[Package(name='example')]

>>> srcinfo.packages_for_architecture(Architecture('aarch64'))
[MergedPackage(architecture=Architecture('aarch64'), name='example', version=FullVersion(pkgver=PackageVersion('0.1.0'), pkgrel=PackageRelease(major=1), epoch=1))]

Working with package metadata

>>> from alpm.alpm_srcinfo.source_info.v1.package import Package, Override
>>> from alpm.alpm_types import License

>>> pkg = Package("testpkg")

>>> pkg.description = Override("A test package")
>>> pkg.description
Override(value='A test package')

>>> pkg.licenses = Override([License("MIT"), License("custom-license")])
>>> pkg.licenses
Override(value=[License('MIT'), License('custom-license')])

>>> {str(lic): lic.is_spdx for lic in pkg.licenses.value}
{'MIT': True, 'custom-license': False}
