The MAGNUM_GL_ABSTRACTSHADERPROGRAM_SUBCLASS_DRAW_IMPLEMENTATION() and
MAGNUM_GL_ABSTRACTSHADERPROGRAM_SUBCLASS_DISPATCH_IMPLEMENTATION() *is*
documented so that one stays not underscored.
Compared to Corrade, the improvement in compile time is about a minute
cumulative across all cores, or about 8 seconds on an 8-core system (~2
minutes before, ~1:52 after). Not bad at all. And this is with a
deprecated build, the non-deprecated build is 1:48 -> 1:41.
Using Containers::Pair allows me to make certain Range APIs constexpr
that weren't possible in C++11 before. Compared to std::pair it's also
trivially copyable, which is a nice property when storing it in various
growable containers.
As usual, the <Corrade/Containers/PairStl.h> include is in place to help
people with porting, although in many cases this change will be
breaking. I had to do it at some point anyway, so the earlier it is the
better.
Instead of defining the same types and vaguely risking little
differences. Typedefs that don't exist in Magnum.h (such as integer
quaternions) and typedefs that differ from Magnum.h (such as
using Vector<4, T> instead of Vector4<T>) stay as typedefs, to make it
clear what *deliberately* differs and what not.
Typedefs that didn't conflict with the template types in Math (such as
Vector3us) are removed entirely, as the typedef from Magnum.h can be
used directly in that case, without any `using`.
I did this back in 2010 because it "felt like the right thing to do",
given that all of Magnum depended on Math and not vice versa. But,
strictly speaking, Math already uses typedefs from Magnum/Types.h so why
it couldn't also bring in the Corrade namespace, and the
Debug/Warning/Error names too. Having to type out Corrade:: in all these
was really just a waste of time, weird inconsistency in docs and an
extra roadblock for whoever might want to contribute anything there.
This makes it possible to conveniently do things like
Containers::StridedArrayView1D<Float> array = …;
Vector4 vector{NoInit};
Utility::copy(array, vector); // or the other way around
which is especially useful together with the new JSON classes. In some
cases this means the function is no longer constexpr, but those weren't
constexpr because it was useful for anything, they were only because it
was possible. So this breakage shouldn't do any harm I think.
Certain Clang-based IDEs (CLion) "emulate" a compiler by inheriting all
its defines, which means one gets __clang__ defined but also __GNUC__
set to 11 or whatever, breaking all these assumptions.
The old one is deprecated, and will be removed in a future release.
Unfortunately, to avoid deprecation warnings, all use of NoInit in the
Math library temporarily have to be Magnum::NoInit This will be cleaned
up when the deprecated alias is removed.
Since Range1D is now used all over Animation, the vector made it very
annoying to use. That's fixed now. This is a backwards-incompatible
change, but I don't expect the 1D range to be used much, mainly because
it was so shitty to use. Generic code that needs a vector can always
cast to it, like this:
Math::Vector<dimensions, T>{range.min()}
Test for the constructor from pair is no longer accepting pairs of 1D
vectors. I have no idea what I meant by that test case (it's testing the
same thing twice), so I removed one of these.
