Two helper +# functions, pypi_sdist_url and pypi_wheel_url are provided to generate +# URLs to artifacts of specified type, with customizable project name. +# Additionally, pypi_wheel_name can be used to generate wheel filename. +# +# @EXAMPLE: +# @CODE@ +# inherit pypi +# +# SRC_URI="$(pypi_sdist_url "${PN^}" "${PV}")" +# S=${WORKDIR}/${P^} +# @CODE@ + +case ${EAPI} in + 8) ;; + *) die "${ECLASS}: EAPI ${EAPI:-0} not supported" ;; +esac + +if [[ ! ${_PYPI_ECLASS} ]]; then +_PYPI_ECLASS=1 + +SRC_URI=" + https://files.pythonhosted.org/packages/source/${PN::1}/${PN}/${P}.tar.gz +" + +# @FUNCTION: pypi_sdist_url +# @USAGE: <project> [<version> [<suffix>]] +# @DESCRIPTION: +# Output the URL to PyPI sdist for specified project/version tuple. +# +# If <version> is unspecified, it defaults to ${PV}. +# +# If <format> is unspecified, it defaults to ".tar.gz".
