It abstracts away the complexity of PyPI URLs, and makes it +easier to adapt ``SRC_URI`` to their future changes. + +Please note that PyPI archives are not always the best choice +for distfiles. In particular, they frequently are missing tests +and other files important to Gentoo packaging. Should that be the case, +other archives should be used. Read the :ref:`source archives` section +for more information. + +Eclass reference: `pypi.eclass(5)`_ + + +Packages with matching name and version +======================================= +In the most common case, the upstream package will have exactly the same +name as the Gentoo package, and the version numbers will be entirely +compatible. In this case, it is sufficient to inherit the eclass, +and it will automatically set a suitable default ``SRC_URI``. The URI +will be equivalent to:: + + SRC_URI=" + https://files.pythonhosted.org/packages/source/${PN::1}/${PN}/${P}.tar.gz + " + +Note that ``SRC_URI`` is not combined between eclasses and ebuilds. +Should you need to fetch additional files, you need to explicitly append +to the variable or the default will be overwritten, e.g.:: + + inherit distutils-r1 pypi + + SRC_URI+=" + https://github.com/pytest-dev/execnet/commit/c0459b92bc4a42b08281e69b8802d24c5d3415d4.patch + -> ${P}-pytest-7.2.patch + " + + +Customizing the generated URL +============================= +The default value may not be suitable for your package if it uses +a different project name, version numbers that are incompatible with +Gentoo or the legacy ``.zip`` sdist format. The ``pypi_sdist_url`` +function can be used to generate URLs in that case. Its usage is:: + + pypi_sdist_url [<project> [<version> [<suffix>]]] + +with package defaulting to ``${PN}``, version to ``${PV}`` and suffix +to ``.tar.gz``.
