But maybe if waf can compile things in a smarter way. Every time I edited document.h, I has to wait a long time for the compile because
it
currently compiles every included file (and I understand why it
might
need to) but perhaps some kind of manual command to say `make
document.o
only and relink`
If you edit document.h, you must rebuild every file that includes document.h - there is no way around that, in any build system in existence. It is theoretically possible to check whether the edits change API/ABI and only recompile then, but this would be incredibly complex to implement; I don't even know whether this is possible at all.
The problem will disturb less when we have modules[1] in C++. Unfortunately, the spec was getting more complex after each iteration.
