Hi:
A couple of times recently, I’ve noticed boilerplate in ports that require
C++14. After including the compiler_blacklist_versions portgroup, they then do
some gymnastics like:
compiler.blacklist *gcc-3.* *gcc-4.* {*gcc-5.[0-3]} \
{clang < 800} macports-clang-3.4 macports-clang-3.5
macports-clang-3.6 macports-clang-3.7
Would it not be easier to use and maintain if we had some shorthand
definitions. Maybe something like:
compiler.blacklist ${min_cxx14}
“min_cxx14” would be defined in the portgroup and then expand to the
above...assuming the above actually does a good job of blacklisting compilers
that don’t support C++14!
A major advantage is that if our list of non-C++14 compilers ever changes, it
only needs to be updated in one spot.
I suspect there would be a few other shorthand lists that could be pre-defined.
Thoughts?
