There's a few cases where something is a huge list of space-separated things, and it is desireable to remove one. The example currently afflicting me is DISTRO_FEATURES_LIBC_DEFAULT; I want to end up with the distro features including all but one of the words in it.
It seems to me that a counterpart to _append would make sense. Here is my basic idea: FOO_subtract = "..." means that, when you expand FOO: 1. Fully expand it. 2. Fully expand FOO_subtract. 3. Remove any words in FOO_subtract from FOO. 4. Yield the result. The rationale is that the semantics of things where we're using _append seem to be consistently of the form "this is a space-separated set", and being able to remove things from a set would be Super Handy. So I'm proposing the semantics for consideration, and if people like them, I will go try to implement it in my Copious Free Time. -s -- Listen, get this. Nobody with a good compiler needs to be justified. _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core
