# @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 python-r1 will always inherit python-utils-r1 as
|
|
# well. Thus, all the functions defined there can be used
|
|
# in the packages using python-r1, and there is no need ever to inherit
|
|
# both.
|
|
#
|
|
# For more information, please see the python-r1 Developer's Guide:
|
|
# http://www.gentoo.org/proj/en/Python/python-r1/dev-guide.xml

# @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.
|
|
#
|
|
# Example:
|
|
# @CODE
|
|
# PYTHON_COMPAT=( python2_5 python2_6 python2_7 )
|
|
# @CODE
|
|
#
|
|
# Please note that you can also use bash brace expansion if you like:

# @ECLASS-VARIABLE: PYTHON_COMPAT_OVERRIDE
|
|
# @INTERNAL
|
|
# @DESCRIPTION:
|
|
# This variable can be used when working with ebuilds to override
|
|
# the in-ebuild PYTHON_COMPAT. It is a string listing all
|
|
# the implementations which package will be built for. It need be
|
|
# specified in the calling environment, and not in ebuilds.
|
|
#
|
|
# It should be noted that in order to preserve metadata immutability,
|
|
# PYTHON_COMPAT_OVERRIDE does not affect IUSE nor dependencies.
|
|
# The state of PYTHON_TARGETS is ignored, and all the implementations
|
|
# in PYTHON_COMPAT_OVERRIDE are built. Dependencies need to be satisfied
|
|
# manually.
|
|
#
|
|
# Example:
|
|
# @CODE
|
|
# PYTHON_COMPAT_OVERRIDE='pypy2_0 python3_3' emerge -1v dev-python/foo
|
|
# @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.
|
|
#
|
|
# This should be set before calling `inherit'.
|
|
#
|
|
# 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="${PYTHON_DEPS}
|
|
# dev-foo/mydep"
|
|
# DEPEND="${RDEPEND}"
|
|
# @CODE
|
|
#
|
|
# Example value:
|
|
# @CODE
|
|
# dev-python/python-exec:=
|
|
# python_targets_python2_6? ( dev-lang/python:2.6[gdbm] )
|
|
# python_targets_python2_7? ( dev-lang/python:2.7[gdbm] )
|
|
# @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:
|
|
# @CODE
|
|
# RDEPEND="dev-python/foo[${PYTHON_USEDEP}]"
|
|
# @CODE
|
|
#
|
|
# Example value:
|
|
# @CODE
|
|
# python_targets_python2_6(-)?,python_targets_python2_7(-)?
|
|
# @CODE
|
|
|
|
# @ECLASS-VARIABLE: PYTHON_REQUIRED_USE
|
|
# @DESCRIPTION:
|
|
# This is an eclass-generated required-use expression which ensures at
|
|
# least one Python implementation has been enabled.
|
|
#
|
|
# This expression should be utilized in an ebuild by including it in
|
|
# REQUIRED_USE, optionally behind a use flag.
|
|
#
|
|
# Example use:
|
|
# @CODE
|
|
# REQUIRED_USE="python? ( ${PYTHON_REQUIRED_USE} )"
|
|
# @CODE
|
|
#
|
|
# Example value:
|
|
# @CODE
|
|
# || ( python_targets_python2_6 python_targets_python2_7 )
