# TODO: Split the "/usr/bin/shiboken2" binding generator from the
# "/usr/lib64/libshiboken2-*.so" family of shared libraries. The former
# requires everything (including Clang) at runtime; the latter only requires
# Qt and Python at runtime. Note that "pip" separates these two as well. See:
# https://doc.qt.io/qtforpython/shiboken2/faq.html#is-there-any-runtime-dependency-on-the-generated-binding
# Once split, the PySide2 ebuild should be revised to require
# "/usr/bin/shiboken2" at build time and "libshiboken2-*.so" at runtime.
# TODO: Add PyPy once officially supported. See also:
# https://bugreports.qt.io/browse/PYSIDE-535

# Shiboken2 assumes the "/usr/lib/clang/${CLANG_NEWEST_VERSION}/include/"
# subdirectory provides Clang builtin includes (e.g., "stddef.h") for the
# currently installed version of Clang, where ${CLANG_NEWEST_VERSION} is
# the largest version specifier that exists under the "/usr/lib/clang/"
# subdirectory. This assumption is false in edge cases, including when
# users downgrade from newer Clang versions but fail to remove those
# versions with "emerge --depclean". See also:
# https://github.com/leycec/raiagent/issues/85
#
# Sadly, the clang-* family of functions exported by the "toolchain-funcs"
# eclass are defective, returning nonsensical placeholder strings if the
# end user has *NOT* explicitly configured their C++ compiler to be Clang.
# PySide2 does *NOT* care whether the end user has done so or not, as
# PySide2 unconditionally requires Clang in either case. This requires us
# to temporarily coerce the "${CPP}" environment variable identifying the
# current C++ compiler to "clang" immediately *BEFORE* calling such a
# function and then restoring that variable to its prior state immediately
# *AFTER* returning from that function call merely to force the
# clang-fullversion() function called below to return sanity. See also:
# https://bugs.gentoo.org/619490
