I'd say "mostly C11": it uses __VA_OPT__ that's been standardized only in C23.
The "foreach" macros need a lot of refinement: passing the body in the parameters is asking for troubles, for example. And using a non-unique default name for the index prevents nested loops.
To overcome the issues with generic and qualified types, have you considered using typeof_unqual?
_Generic(*(typeof_unqual(x)*)0, ...)I do kinda like how foreach is implemented right now. This allows me to perform some strict checking for easy loop iteration based bugs and also it kinda looks cool.
This is the first time I came across typeof_unqual. I'll look into it, thanks .
I spent a lot of time making this work across all three compilers (especially MSVC). I'm glad MSVC has VA_OPT support.
Yes but the body in the parameters really is a show stopper. What if the body has a unprotected comma? Like
VecForeach(&v, e, {
int x, y;
...
});
#define VecForeachIdx(v, var, idx)\
for (size idx=0,_d=1; ValidateVec(v),_d; _d--)\
for (VEC_DATATYPE(v) var={}; idx<(v)->length && (var=VecAt(v,idx),1); idx++)
