[gentoo-dev] [PATCH 0/5] python-r1 suite: python_gen_impl_dep() function

["Michał Górny" <mgorny@gentoo.org>]

Hi,

Here's a quick set of patches that add python_gen_impl_dep() function
to python-r1 and python-single-r1 eclasses, and use them in a few
ebuilds.

The problem solved is that some Python packages need to depend on more
than one combination of USE flags on the Python interpreter. Currently,
we solved this through bash-substituting USE dependencies in generated
${PYTHON_DEPS} -- though this was kinda ugly.

The python_gen_impl_dep() function intends to match API of other
functions. In particular, its usage is:

  python_gen_impl_dep <req-use> [<impl-pattern>...]

where req-use defines the USE-dep for Python interpreters (alike
PYTHON_REQ_USE) and can optionally be an empty string, and impl-patterns
specify PYTHON_COMPAT patterns to match implementations that will be
present in the dependency. If no patterns are passed, '*' is assumed.

Examples (for PYTHON_COMPAT=( python2_7 python3_4 )):

  python_gen_impl_dep 'bzip2(+)'

    python_targets_python2_7? ( dev-lang/python:2.7[bzip2(+)] )
    python_targets_python3_4? ( dev-lang/python:3.4[bzip2(+)] )

  python_gen_impl_dep ''

    python_targets_python2_7? ( dev-lang/python:2.7 )
    python_targets_python3_4? ( dev-lang/python:3.4 )

  python_gen_impl_dep '' python3*

    python_targets_python3_4? ( dev-lang/python:3.4 )

Please review the patches sent in reply.
