Consistently with changes done to Utility::Path, this enforces proper
error handling on user side. Originally I didn't want to do this and
instead wanted to have a special Array instance devoted for an error
state, but that still would allow the error state be errorneously
treated as a successful but empty array.
It's more useful if the Error class is directly referenced than saying
just "error output" -- so people can grab it, redirect it, etc. Also
drop the useless "does what it is expected to do on success" sentences
that add no value whatsoever.
It limits the support for CMake 3.12+, but it's much less verbose and I
don't expect people to use ancient CMake versions with IDEs like Xcode
or VS anyway, so this should be fine.
I wanted to avoid including extra stuff with the Manager.hpp split, but
this would make it even worse than having Array and String included
unconditionally. Fortunately it's enough to simply not even have the
declaration.
Probably a leftover from when these dependencies were handled in a
much shittier way? For as long as I remember, enabling WITH_GL_INFO
always enabled WITH_GL and WITH_WINDOWLESSWHATEVERAPPLICATION
implicitly.
Minor but very important convenience feature, especially useful when
dealing with command-line apps. This now works:
magnum-imageconverter a.png a.jpg -c jpegQuality=0.75
The AnyImageConverter gets the jpegQuality option and then
automatically propagates it to the concrete plugin (which is either
JpegImageConverter or StbImageConverter), possibly warning in case the
target plugin doesn't recognize given option (i.e., doesn't list it in
its default configuration). Previously the user had to always specify a
concrete converter implementation using -C, which was rather annoying
and nonintuitive.
There will be Flag::FlipY for images at some point, enabled by default
for compatibility with existing GL code, and so it makes sense to start
discouraging setFlags() as early as possible to avoid people resetting
the default by accident.
Also update the imageconverter, sceneconverter and shaderconverter utils
to use these instead of setFlags().
Currently those will be needed mainly by the Vk library to patch around
a SwiftShader bug. I'm not sure yet how the public API should look so
it's all hidden in the Implementation namespace for now.
If it's ignored, a warning is printed to catch accidents, but not an
error since it should be possible to just append --info to existing
command line to see what the input is about.
Sigh, again. That's what I get for removing std::string only from some
APIs and not all. Explicitly fetching the argument values as a
StringView everywhere now, it avoids a copy so it's good to do even if
not strictly needed.
To make it convenient, the format equals to the usual file extension.
Currently skipping WGSL and DXIL however because I have no idea what
extension should they have, not even the DirectXShaderCompiler repo
tests show anything useful, there it's either generic LLVM *.ll or *.bc.
Come on, did people in 2020 also forget how to design file formats?!
