Similarly as done in Aug 2024 in Corrade. When these were a part of the
function signature, they ended up being encoded into the exported
symbol. There are still cases of StridedArrayView slice() having
enable_if in the signature, which amounts to about 18 kB symbols in all
libMagnum*-d.so libraries, but apart from that this is the state before:
$ strings libMagnum*-d.so | grep enable_if | grep -v slice | wc -c
29591
And this is after. All of those are coming from STL, thus from
old or deprecated APIs that still use std::vector, std::tuple and such,
and from the few std::sort() uses.
$ strings libMagnum*-d.so | grep enable_if | grep -v slice | wc -c
4103
In a non-deprecated build it's just this, which is a 10x reduction.
Can't really do much about these maybe exceút for implementing my own
swap() specializations (sigh?), but I think it's fine.
$ strings libMagnum*-d.so | grep enable_if | grep -v slice | wc -c
2904
I also made it consistently use
typename std::enable_if<..., int>::type = 0
instead of
class = typename std::enable_if<...>::type
because the former works correctly also in presence of overloads and
having it used consistently everywhere makes it easier to grep & change
later. All SFINAE is now also excluded from Doxygen output, because it
doesn't make much sense there. It's better to just explain the
restriction in words than with this nasty hack.
Doxygen 1.12 has no longer a completely insane matcher and discards
those as it should. With 1.8.17 classes had to be referenced with
Corrade:: but functions, typedefs and variables didn't need to be and it
was a complete utter chaos.
Explicitly provide conversion to Vector2 and Vector3 in addition to
Vector<2> / Vector<3> as otherwise creating a TextureData from an
Array3D will fail, breaking the compilation of TinyGltfImporter.
Its only use was for specifying N-dimensional SamplerWrapping because,
compared to a Math::Vector, it had an implicit constructor from a single
value (whereas the Vector has it explicit). I solved that by simply
adding a few single-value overloads where it mattered. There, done. No
need for this weird thing and confusion with Containers::Array anymore.
All places that used it now use Math::VectorN<SamplerWrapping>, but the
class is still included for backwards compatibility purposes, together
with providing implicit conversion from and to a Vector.
The only places where they aren't absolute are:
- when header is included from corresponding source file
- when including headers which are not part of final installation (e.g.
test-specific configuration, headers from Implementation/)
Everything what was in src/ is now in src/Corrade, everything from
src/Plugins is now in src/MagnumPlugins, everything from external/ is in
src/MagnumExternal. Added new CMakeLists.txt file and updated the other
ones for the moves, no other change was made. If MAGNUM_BUILD_DEPRECATED
is set, everything compiles and installs like previously except for the
plugins, which are now in MagnumPlugins and not in Magnum/Plugins.
Merged constexpr test cases into other ones to remove duplicate code.
Copied the constructors from Math::Vector as I don't feel reinventing
all that again.
It prevents unwanted implicit conversions from e.g. nullptr to Camera,
Vector2 to Physics::Point etc. By making all the constructors explicit
it is easier to routinely add the keyword to all new classes instead of
thinking about cases when to add and when not to.
