# @ECLASS: distutils-r1
# @MAINTAINER:

# @BLURB: A simple eclass to build Python packages using distutils.
# @DESCRIPTION:
# A simple eclass providing functions to build Python packages using
# the distutils build system. It exports phase functions for all
# the src_* phases. Each of the phases runs two pseudo-phases:
# python_..._all() (e.g. python_prepare_all()) once in ${S}, then
# python_...() (e.g. python_prepare()) for each implementation
# (see: python_foreach_impl() in python-r1).
#
# In distutils-r1_src_prepare(), the 'all' function is run before
# per-implementation ones (because it creates the implementations),
# per-implementation functions are run in a random order.
#
# In remaining phase functions, the per-implementation functions are run
# before the 'all' one, and they are ordered from the least to the most
# preferred implementation (so that 'better' files overwrite 'worse'
# ones).
#
# If the ebuild doesn't specify a particular pseudo-phase function,
# the default one will be used (distutils-r1_...). Defaults are provided
# for all per-implementation pseudo-phases, python_prepare_all()
# and python_install_all(); whenever writing your own pseudo-phase
# functions, you should consider calling the defaults (and especially
# distutils-r1_python_prepare_all).
#
# Please note that distutils-r1 sets RDEPEND and DEPEND unconditionally
# for you.
#
# Also, please note that distutils-r1 will always inherit python-r1
# as well. Thus, all the variables defined and documented there are
# relevant to the packages using distutils-r1.
#
# For more information, please see the python-r1 Developer's Guide:
# http://www.gentoo.org/proj/en/Python/python-r1/dev-guide.xml

# @ECLASS-VARIABLE: DISTUTILS_OPTIONAL
# @DEFAULT_UNSET
# @DESCRIPTION:
# If set to a non-null value, distutils part in the ebuild will
# be considered optional. No dependencies will be added and no phase
# functions will be exported.
#
# If you enable DISTUTILS_OPTIONAL, you have to set proper dependencies
# for your package (using ${PYTHON_DEPS}) and to either call
# distutils-r1 default phase functions or call the build system
# manually.

# @ECLASS-VARIABLE: DISTUTILS_SINGLE_IMPL
# @DEFAULT_UNSET
# @DESCRIPTION:
# If set to a non-null value, the ebuild will support setting a single
# Python implementation only. It will effectively replace the python-r1
# eclass inherit with python-single-r1.
#
# Note that inheriting python-single-r1 will cause pkg_setup()
# to be exported. It must be run in order for the eclass functions
# to function properly.

# @ECLASS-VARIABLE: PATCHES
# @DEFAULT_UNSET
# @DESCRIPTION:
# An array containing patches to be applied to the sources before
# copying them.
#
# If unset, no custom patches will be applied.
#
# Please note, however, that at some point the eclass may apply
# additional distutils patches/quirks independently of this variable.
#
# Example:
# @CODE
# PATCHES=( "${FILESDIR}"/${P}-make-gentoo-happy.patch )
# @CODE

# @ECLASS-VARIABLE: DOCS
# @DEFAULT_UNSET
# @DESCRIPTION:
# An array containing documents installed using dodoc. The files listed
# there must exist in the directory from which
# distutils-r1_python_install_all() is run (${S} by default).
#
# If unset, the function will instead look up files matching default
# filename pattern list (from the Package Manager Specification),
# and install those found.
#
# Example:
# @CODE
# DOCS=( NEWS README )
# @CODE

# @ECLASS-VARIABLE: HTML_DOCS
# @DEFAULT_UNSET
# @DESCRIPTION:
# An array containing documents installed using dohtml. The files
# and directories listed there must exist in the directory from which
# distutils-r1_python_install_all() is run (${S} by default).
#
# If unset, no HTML docs will be installed.
#
# Example:
# @CODE
# HTML_DOCS=( doc/html/. )
# @CODE

# @ECLASS-VARIABLE: EXAMPLES
# @DEFAULT_UNSET
# @DESCRIPTION:
# An array containing examples installed into 'examples' doc
# subdirectory. The files and directories listed there must exist
# in the directory from which distutils-r1_python_install_all() is run
# (${S} by default).
#
# The 'examples' subdirectory will be marked not to be compressed
# automatically.
#
# If unset, no examples will be installed.
#
# Example:
# @CODE
# EXAMPLES=( examples/. demos/. )
# @CODE

# @ECLASS-VARIABLE: DISTUTILS_IN_SOURCE_BUILD
# @DEFAULT_UNSET
# @DESCRIPTION:
# If set to a non-null value, in-source builds will be enabled.
# If unset, the default is to use in-source builds when python_prepare()
# is declared, and out-of-source builds otherwise.
#
# If in-source builds are used, the eclass will create a copy of package
# sources for each Python implementation in python_prepare_all(),
# and work on that copy afterwards.
#
# If out-of-source builds are used, the eclass will instead work
# on the sources directly, prepending setup.py arguments with
# 'build --build-base ${BUILD_DIR}' to enforce keeping & using built
# files in the specific root.

# @ECLASS-VARIABLE: DISTUTILS_NO_PARALLEL_BUILD
# @DEFAULT_UNSET
# @DESCRIPTION:
# If set to a non-null value, the parallel build feature will
# be disabled.
#
# When parallel builds are used, the implementation-specific sub-phases
# for selected Python implementation will be run in parallel. This will
# increase build efficiency with distutils which does not do parallel
# builds.
#
# This variable can be used to disable the afore-mentioned feature
# in case it causes issues with the package.

# @ECLASS-VARIABLE: mydistutilsargs
# @DEFAULT_UNSET
# @DESCRIPTION:
# An array containing options to be passed to setup.py.
#
# Example:
# @CODE
# python_configure_all() {
# 	mydistutilsargs=( --enable-my-hidden-option )
# }
# @CODE

# @FUNCTION: esetup.py
# @USAGE: [<args>...]
# @DESCRIPTION:
# Run setup.py using currently selected Python interpreter
# (if ${PYTHON} is set; fallback 'python' otherwise).
#
# setup.py will be passed the following, in order:
# 1. ${mydistutilsargs[@]}
# 2. additional arguments passed to the esetup.py function.
#
# Please note that setup.py will respect defaults (unless overriden
# via command-line options) from setup.cfg that is created
# in distutils-r1_python_compile and in distutils-r1_python_install.
#

#
# Please note that this function should be only used if package uses

	# 3) non-root 'install' complains about PYTHONPATH and missing dirs,
	#    so we need to set it properly and mkdir them,
	# 4) it runs a bunch of commands which write random files to cwd,
