# @BLURB: A common, simple eclass for Python packages.
|
|
|
|
# @DESCRIPTION:
|
|
|
|
# A common eclass providing helper functions to build and install
|
|
|
|
# packages supporting being installed for multiple Python
|
|
|
|
# implementations.
|
|
|
|
#
|
|
|
|
# This eclass sets correct IUSE and REQUIRED_USE. It exports PYTHON_DEPS
|
|
|
|
# and PYTHON_USEDEP so you can create correct dependencies for your
|
|
|
|
# package easily. It also provides methods to easily run a command for
|
|
|
|
# each enabled Python implementation and duplicate the sources for them.
|
|
|
|
#
|
|
|
|
# Please note that this eclass is mostly intended to be extended
|
|
|
|
# on-request. If you find something you used in other eclasses missing,
|
|
|
|
# please don't hack it around and request an enhancement instead.

# @DESCRIPTION:
|
|
|
|
# This variable contains a list of Python implementations the package
|
|
|
|
# supports. It must be set before the `inherit' call. It has to be
|
|
|
|
# an array.
|
|
|
|
#
|
|
|
|
# The default is to enable all supported implementations. However, it is
|
|
|
|
# discouraged to use that default unless in very special cases and test
|
|
|
|
# the package with each added implementation instead.
|
|
|
|
#
|
|
|
|
# Example:
|
|
|
|
# @CODE
|
|
|
|
# PYTHON_COMPAT=( python2_5 python2_6 python2_7 )
|
|
|
|
# @CODE

# @ECLASS-VARIABLE: PYTHON_REQ_USE
|
|
|

# @DEFAULT_UNSET

|
|
|
# @DESCRIPTION:
|
|
|
|
# The list of USEflags required to be enabled on the chosen Python
|
|
|
|
# implementations, formed as a USE-dependency string. It should be valid
|
|
|
|
# for all implementations in PYTHON_COMPAT, so it may be necessary to
|
|
|
|
# use USE defaults.
|
|
|
|
#
|
|
|
|
# Example:
|
|
|
|
# @CODE
|
|
|
|
# PYTHON_REQ_USE="gdbm,ncurses(-)?"
|
|
|
|
# @CODE
|
|
|
|
#
|
|
|
|
# It will cause the Python dependencies to look like:
|
|
|
|
# @CODE
|
|
|
|
# python_targets_pythonX_Y? (
|
|
|
|
# dev-lang/python:X_Y[gdbm,ncurses(-)?] )
|
|
|
|
# @CODE
|
|
|
|
|
|
|
|
# @ECLASS-VARIABLE: PYTHON_DEPS
|
|
|
|
# @DESCRIPTION:
|
|
|
|
# This is an eclass-generated Python dependency string for all
|
|
|
|
# implementations listed in PYTHON_COMPAT.
|
|
|
|
#
|
|
|
|
# Example use:
|
|
|
|
# @CODE
|
|
|
|
# RDEPEND="${PYTHON_DEPS}
|
|
|
|
# dev-foo/mydep"

|
|
|
|
# @CODE
|
|
|
|
|
|
|
|
# @ECLASS-VARIABLE: PYTHON_USEDEP
|
|
|
|
# @DESCRIPTION:
|
|
|
|
# This is an eclass-generated USE-dependency string which can be used to
|
|
|
|
# depend on another Python package being built for the same Python
|
|
|
|
# implementations.
|
|
|
|
#
|
|
|
|
# The generate USE-flag list is compatible with packages using python-r1
|
|
|
|
# and python-distutils-ng eclasses. It must not be used on packages
|
|
|
|
# using python.eclass.
|
|
|

#
|
|

|
# Example use:
