# @BLURB: An eclass for Python packages not installed for multiple implementations.
|
|
# @DESCRIPTION:
|
|
# An extension of the python-r1 eclass suite for packages which
|
|
# don't support being installed for multiple Python implementations.
|
|
# This mostly includes tools embedding Python and packages using foreign
|
|
# build systems.
|
|
#
|
|
# This eclass sets correct IUSE. It also provides PYTHON_DEPS
|
|
# and PYTHON_REQUIRED_USE that need to be added to appropriate ebuild
|
|
# metadata variables.
|
|
#
|
|
# The eclass exports PYTHON_SINGLE_USEDEP that is suitable for depending
|
|
# on other packages using the eclass. Dependencies on packages using
|
|
# python-r1 should be created via python_gen_cond_dep() function,
|
|
# using PYTHON_MULTI_USEDEP placeholder.
|
|
#
|
|
# Please note that packages support multiple Python implementations
|
|
# (using python-r1 eclass) can not depend on packages not supporting
|
|
# them (using this eclass).
|
|
#
|
|
# Please note that python-single-r1 will always inherit python-utils-r1
|
|
# as well. Thus, all the functions defined there can be used
|
|
# in the packages using python-single-r1, and there is no need ever
|
|
# to inherit both.
|
|
#
|
|
# For more information, please see the wiki:
|
|
# https://wiki.gentoo.org/wiki/Project:Python/python-single-r1

# @ECLASS-VARIABLE: PYTHON_COMPAT
|
|
# @REQUIRED
|
|
# @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_7 python3_3 python3_4 )
|
|
# @CODE
|
|
#
|
|
# Please note that you can also use bash brace expansion if you like:
|
|
# @CODE
|
|
# PYTHON_COMPAT=( python2_7 python3_{3,4} )
|
|
# @CODE
|
|
|
|
# @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 naming the implementation
|
|
# which package will be built for. It needs to 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 and PYTHON_SINGLE_TARGET is ignored,
|
|
# and the implementation in PYTHON_COMPAT_OVERRIDE is built instead.
|
|
# Dependencies need to be satisfied manually.
|
|
#
|
|
# Example:
|
|
# @CODE
|
|
# PYTHON_COMPAT_OVERRIDE='pypy' emerge -1v dev-python/bar
|
|
# @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_single_target_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.
|
|
#
|
|
# The dependency string is conditional on PYTHON_SINGLE_TARGET.
|
|
#
|
|
# Example use:
|
|
# @CODE
|
|
# RDEPEND="${PYTHON_DEPS}
|
|
# dev-foo/mydep"
|
|
# DEPEND="${RDEPEND}"
|
|
# @CODE
|
|
#
|
|
# Example value:
|
|
# @CODE
|
|
# dev-lang/python-exec:=
|
|
# python_single_target_python2_7? ( dev-lang/python:2.7[gdbm] )
|
|
# python_single_target_pypy? ( virtual/pypy[gdbm] )
|
|
# @CODE
|
|
|
|
# @ECLASS-VARIABLE: PYTHON_USEDEP
|
|
# @DESCRIPTION:
|
|
# DEPRECATED. Use PYTHON_SINGLE_USEDEP or python_gen_cond_dep with
|
|
# PYTHON_MULTI_USEDEP placeholder instead.
|
|
#
|
|
# 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,
|
|
# python-single-r1 and python-distutils-ng eclasses. It must not be used
|
|
# on packages using python.eclass.
|
|
#
|
|
# Example use:
|
|
# @CODE
|
|
# RDEPEND="dev-python/foo[${PYTHON_USEDEP}]"
|
|
# @CODE
|
|
#
|
|
# Example value:
|
|
# @CODE
|
|
# python_targets_python2_7(-)?,python_single_target_python3_4(+)?
|
|
# @CODE
|
|
|
|
# @ECLASS-VARIABLE: PYTHON_SINGLE_USEDEP
|
|
# @DESCRIPTION:
|
|
# This is an eclass-generated USE-dependency string which can be used to
|
|
# depend on another python-single-r1 package being built for the same
|
|
# Python implementations.
|
|
#
|
|
# If you need to depend on a multi-impl (python-r1) package, use
|
|
# python_gen_cond_dep with PYTHON_MULTI_USEDEP placeholder instead.
|
|
#
|
|
# Example use:
|
|
# @CODE
|
|
# RDEPEND="dev-python/foo[${PYTHON_SINGLE_USEDEP}]"
|
|
# @CODE
|
|
#
|
|
# Example value:
|
|
# @CODE
|
|
# python_single_target_python3_4(-)?
|
|
# @CODE
|
|
|
|
# @ECLASS-VARIABLE: PYTHON_MULTI_USEDEP
|
|
# @DESCRIPTION:
|
|
# This is a placeholder variable supported by python_gen_cond_dep,
|
|
# in order to depend on python-r1 packages built for the same Python
|
|
# implementations.
|
|
#
|
|
# Example use:
|
|
# @CODE
|
|
# RDEPEND="$(python_gen_cond_dep '
|
|
# dev-python/foo[${PYTHON_MULTI_USEDEP}]
|
|
# ')"
|
|
# @CODE
|
|
#
|
|
# Example value:
|
|
# @CODE
|
|
# python_targets_python3_4(-)
|
|
# @CODE
|
|
|
|
# @ECLASS-VARIABLE: PYTHON_REQUIRED_USE
|
|
# @DESCRIPTION:
|
|
# This is an eclass-generated required-use expression which ensures the following
|
|
# when more than one python implementation is possible:
|
|
# 1. Exactly one PYTHON_SINGLE_TARGET value has been enabled.
|
|
# 2. The selected PYTHON_SINGLE_TARGET value is enabled in PYTHON_TARGETS.
|
|
#
|
|
# 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
|
|
#
|
|

# @USAGE: [<requested-use-flags> [<impl-pattern>...]]
|
|
# @DESCRIPTION:
|
|
# Output a dependency on Python implementations with the specified USE
|
|
# dependency string appended, or no USE dependency string if called
|
|
# without the argument (or with empty argument). If any implementation
|
|
# patterns are passed, the output dependencies will be generated only
|
|
# for the implementations matching them.
|
|
#
|
|
# The patterns can be either fnmatch-style patterns (matched via bash
|
|
# == operator against PYTHON_COMPAT values) or '-2' / '-3' to indicate
|
|
# appropriately all enabled Python 2/3 implementations (alike
|
|
# python_is_python3). Remember to escape or quote the fnmatch patterns
|
|
# to prevent accidental shell filename expansion.
|
|
#
|
|
# Use this function when you need to request different USE flags
|
|
# on the Python interpreter depending on package's USE flags. If you
|
|
# only need a single set of interpreter USE flags, just set
|
|
# PYTHON_REQ_USE and use ${PYTHON_DEPS} globally.
|
|
#
|
|
# Example:
|
|
# @CODE
|
|
# PYTHON_COMPAT=( python{2_7,3_{3,4}} pypy )
|
|
# RDEPEND="foo? ( $(python_gen_impl_dep 'xml(+)') )"
|
|
# @CODE
|
|
#
|
|
# It will cause the variable to look like:
|
|
# @CODE
|
|
# RDEPEND="foo? (
|
|
# python_single_target_python2_7? (
|
|
# dev-lang/python:2.7[xml(+)] )
|
|
# python_single_target_pypy? (
|
|
# dev-python/pypy[xml(+)] ) )"
|
|
# @CODE
