# @BLURB: common ebuild functions for waf-based packages
# @DESCRIPTION:
# The waf-utils eclass contains functions that make creating ebuild for
# waf-based packages much easier.
# Its main features are support of common portage default settings.

# @FUNCTION: waf-utils_waflibdir
# @USAGE: [<waf-binary>]
# @DESCRIPTION:
# Echoes the absolute path to the directory containing the waf-based
# project's waflib python module. Ensures that the waflib shipped with a
# project is unpacked if it isn't already. This waflib may be safely
# patched because waf-lite will not touch the waflib directory if it
# already exists. Uses the waf binary specified in WAF_BINARY.
#
# @EXAMPLE
# The simplest case, for a monolithic compilation:
#
# @CODE
# pushd "$(waf-utils_waflibdir)" || die "Unable to patch waflib"
# epatch "${FILESDIR}"/${P}-waf-fix.patch
# popd
# @CODE
#
# Note that if you are using the python eclass and installating python
# modules, you must either call python_set_active_version or call
# waf-utils_waflibdir() from within a function run by
# python_execute(). This is because waf uses a different directory for
# waflib when using python3 than when using python2.
#
# @CODE
# SUPPORT_PYTHON_ABIS=1
# inherit eutils python waf-utils
#
# # Always use the waf associated with the current python ABI.
# WAF_BINARY=./waf

# epatch "${FILESDIR}"/${P}-sourcecode-fix.patch

# epatch "${FILESDIR}"/${P}-waf-fix.patch
