This avoids the build from erroring out on C4819 (Unicode handling issue in
Visual Studio compiler), notably when running on Chinese, Japanese and
Korean locales.
Also apply -D_USE_MATH_DEFINES, -FImsvc_recommended_pragmas.h and -utf-8 to
the C++ compiler options as well.
Copy just enough of libwayland-cursor to make our own
loading. This lets us drop the dependency on libwayland-cursor,
and changes the startup cost for cursor theme loading
from 25ms to 0.1ms.
At the same time, simplify the handling of scaled cursors -
instead of creating an array of theme objects, just make a
single theme object provide all scaled cursor sizes.
sincosf() is really a GCC-specific function that may more may not be
supported on non-GCC compilers, so we want to check for it, otherwise we
use a fallback implementation, not unlike the one in
demos/gtk-demo/gtkgears.c.
The `name` and `description` events were added to `xdg-output` protocol
in version 2 which is part of wayland-protocols 1.14.
In xdg-output-v1 version 3, the `xdg-output.done` event was deprecated
and the `xdg-output.description` event was made mutable, but that
doesn't change the actual events so we do not actually need to require
that version of xdg-output from wayland-protocols 1.18.
Update the wayland-protocols requirement to the bare minimum version,
which is 1.14.

Use cairo-script-interpreter to parse the scripts that generate cairo
nodes.
This requires libcairoscriptinterpreter.so to work properly, but if
it isn't found we disable this (unimportant for normal functioning)
code and just emits a parser warning.
The testsuite requires it however or it will fail.
A new test is included that tests all of this.
This uses the new sysprof-3 ABI to implement the capture writer. It also
uses the statically linked libsysprof-capture-3.a that is provided with
Sysprof for the capture writing to ensure that we do not leak any symbols
nor depend on any additional libraries.
The GTK_TRACE_FD can be used to pass a FD for tracing into Gtk. Sysprof
uses this when the Gtk instrument is selected for recording.
The 'documentation' option also guarded the man page build. Instead
if skipping the whole docs subdir skip the specific gtkdoc calls, so that the
man page build still works.
This brings it in line with the gtk3 meson build.
XInput2 is more than a decade old already, and the input improvements
there (and in every other backend really) make it untenable to have
support for X11 core input events dragging things behind.
Added two new private GtkWidget API:
* gtk_widget_add_surface_transform_changed_callback()
* gtk_widget_remove_surface_transform_changed_callback()
The intention is to let the user know when a widget transform relative
to the surface changes. It works by calculating the surface relative
transform during allocation, and notifying the callbacks if it changed
since last time. Each widget adds itself as a listener to its parent
widget, thus will be triggered if a parents surface relative transform
changes.
These flags check for code that we don't want to write, so turn them
into error flags.
Variable length arrays should be replaced by malloc() - or explicit
alloca() calls if you know what you're doing.
Implicit fallthrough should be replaced by explicit fallthrough with the
usage of G_GNU_FALLTHROUGH.

This library is meant to be the new CSS library that gets used from GDK,
GSK and GTK for string printing and parsing.
As a first step, move GtkCssProviderError into it.
While doing so, split it into GtkCssParserError (for critical problems)
and GtkCssParserWarning (for non-critical problems).
The current Meson releases have broken CMake support, meaning that it is
likely that HarfBuzz could not be located for Visual Studio builds
unless one handcrafts pkg-config files for it, which is both tedious and
error-prone.
Instead, use the existing mechanism for looking for the HarfBuzz headers
and libraries on Visual Studio first when it could not be found via
dependency(), and then use the fallback if it still could not be found.
In particular, check that to_matrix() and to_2d(), to_affine() and
to_translate() return the same values.
This also requires a recent Graphene version or the tests will fail.
The tests were added when we thought we had to align memory allocations
for structures including a Graphene type in their members. Graphene
added alignment annotations for its types, and we never really used the
symbols we set after testing for allocations being aligned out of the
box with malloc(), and for aligned allocators.
Some of the flags got lost in the meson transition or were demoted from
error flags to warning flags.
This commit reintroduces them.
It also includes fixes for the code that had warnings with those flags.
The big one being -Wshadow.
Using an empty `configuration_data` object to copy a configuration file
is deprecated since Meson 0.47 (released July 2018); the equivalent
behaviour is available by using `copy: true`.
The existing post-install shell script will most likely not work on
Visual Studio builds as there is normally no shell interpreter installed
on the system where the build is done, but the build is normally done in
a standard Windows cmd.exe console.
Instead, use a Python script so that it will work on the platforms that
Python supports.
This meson port is not upstream yet, so a wrap file is not included.
Upstream has expressed interest but the port hasn't been tested on all
platforms yet. Will be added when it gets upstreamed.
Link to WIP port: https://github.com/centricular/harfbuzz
* A bunch of new variables for config.h.meson
* A check for aligned allocation being necessary at all
(graphene must use GCC vector instructions or SSE2)
* A check for C malloc() being aligned at 16-byte boundaries
* A check for a few special aligned allocator functions being
present and not being built-ins (posix_memalign is a builtin
in GCC, even on platforms where there is no posix_memalign
system function)
* Added -mstackrealign flag on Windows, since otherwise
stack variables may become unaligned when the stack briefly
passes through OS code (such as in various callbacks and
handlers)
The header linux/input.h used by GDK is specific to Linux. It is
possible to get a few Linux headers on FreeBSD by installing v4l_compat,
but it is usually better to use the one shipped with FreeBSD.
We prefer dev/evdev/input.h to linux/input.h here, so it will always use
dev/evdev/input.h on FreeBSD regardless of v4l_compat.

This commit adds support the stable version of the xdg-shell protocol.
Support for the last version of the unstable series is left intact, but
will not receive new features.
The stable version is prioritized above the older version.

Instead of hard-coding linker flags for a specific operating system and
a specific compiler, we can should cc.links to test them, so they can be
used on more operating systems and compilers.
All of the four platform-dependent backends are enabled by default. It
is usually a good default because it requires users to explicitly choose
backends they want to use. Rules in meson.build also automatically
disable unavailable backends for macOS, Windows, Linux, so users on
these 3 major platforms don't have to manually disable things when
running meson commands.
However, meson.build doesn't do the same thing for other Unix-like
systems, which is acceptable but not ideal. To make it easier to build
GTK+ on these systems, the Linux case, which enables X11 and Wayland and
disables Win32 and Quartz, is made the default for all operating systems
that are not Windows or macOS.
This commit also changes most 'host_machine.system()' calls to os_*
variables, which are easier to read and less likely to be used wrongly.
Instead of going through an ancillary script to strip away the
`WL_EXPORT` annotation from the generated code, we should bump up the
required version of Wayland, and use the `private-code` argument for
wayland-scanner, which does the right thing for us.
The demos are now built as GUI programs, which will require the presence
of WinMain() on Visual Studio builds, unless we specify the entry point.
Pass the /entry:mainCRTStartup linker flag on Visual Studio builds for
the demo programs so that they can link properly.
https://bugzilla.gnome.org/show_bug.cgi?id=773299
Examples are not like demos; the latter are installed, and provide a
Flatpak manifest for CI pipelines and GNOME Builder. We should not be
using a single configure time option to gate building both.
We forgot to account for the case where we lookup for HarfBuzz manually
under Visual Studio builds, so only set HAVE_HARFBUZZ (and thus
HAVE_PANGOFT, since PangoFT2 depends on HarfBuzz) after we did the
fallback check for HarfBuzz.
Also, check for hb.h instead of harfbuzz/hb.h to be inline with the
pkg-config case, as the sources also include the HarfBuzz header by
using #include <hb.h>, not #include <harfbuzz/hb.h>
https://bugzilla.gnome.org/show_bug.cgi?id=773299
Check for freetype2 version, because pangoft works with any version
(pangoft availability does not indicate that ft2 is new enough), unlike
GTK.
On Windows, since pangoft is optional, we check for the presence of
freetype2 .pc file first after finding that we have pangoft, and then
check for FT_Get_Var_Design_Coordinates() manually by looking for the
freetype headers and .lib first, and then looking for the presence of
that symbol, since freetype2's Visual Studio build system does not
generate a .pc file for us.
https://bugzilla.gnome.org/show_bug.cgi?id=773299
Meson warns when doing that, as it's not really portable.
Since we're using platform-specific linker flags on Darwin, we can also
do the same on Linux; the syntax is GCC-specific, so we're going to need
Clang users to test it.
This way, we can support external libraries providing implementations of
GtkMediaFile.
We also add a media backend called 'nomedia' that can be enabled to not
compile any support for GtkMediaFile. This is useful when people want to
statically compile GTK into an application that does not use media.
For now, this option is the default.
We also support a new environment variable GTK_MEDIA that allows
selecting the implementation to use.
GTK_MEDIA=help can be used to get info about the available
implementations.
This makes demos be compiled/linked before tests. And that means that
while hacking, I can already run widget-factory when the tests are
still linking.
Release builds should only disable cast checks, to match what we used
to do back with the Autotools builds.
The Autotools build had an "--enable-debug=no" option, but that was
rarely used; Meson has debug, debugoptimized, release, and plain build
types, but we considered the "release" build types as the old "disable
all debugging code", which is not really accurate.
Disabling assertions and preconditon checks should be left to people
with constrained environments and/or packagers; they are supposed to
use the "plain" build type, and override the CFLAGS themselves.
Drop the 'enable-' prefix, and always enable all platform-specific
backends. We can disable them depending on the platform. This way,
the documentation printed by `meson configure` remains accurate.
Instead of having separate options for each print backend, we can use
the same approach as the input method modules: a single option, with a
comma-separated list of print backends.
The standard Vulkan SDK ships with a pkg-config file, like a modern
library should.
We should fall back to finding the library and header only for platforms
where pkg-config is not really a thing.
Based on a patch by: Daniel Stone <daniels@collabora.com>

Add the necessary machinery into the Meson definition files so that we
can build for Windows.
Since we don't have Wayland or X support for our use case here, disable
them once we know that we are building for Windows, as they are
(otherwise) enabled by default, and enable the items that need to be
built for Windows builds.
Exclude gtk4-launch from Windows builds as that is something that
is not supported on Windows.
As we won't have gio-unix on Windows, and PangoFT2 is optional, don't use
fallbacks for them when we are on Windows (but do use fallbacks for
gio-win32, as it will be used).
Also, clean up meson.build a bit as we can just force-include
msvc_recommended_pragmas.h from GLib since we depend on GLib, and so we
can handle these warnings from msvc_recommended_pragmas.h instead.
https://bugzilla.gnome.org/show_bug.cgi?id=785210
This patch makes that work using 1 of 2 options:
1. Add all missing enums to the switch statement
or
2. Cast the switch argument to a uint to avoid having to do that (mostly
for GdkEventType).
I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.
The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.
-Wshadow these days does not overwarn anymore like it did in gcc 4.
There are no warnings inside gtk, so better enable it to keep it that
way.
-Wuninitialized also has no positives, so I'm gonna turn it on just
because.
-Wint-conversion is important because it checks casts from ints to
pointers.
-Wdiscarded-qualifiers is important to catch cases where we don't
strings when we should.
Otherwise it fails to build with:

For dependencies that do not generate pkg-config files for their Visual
Studio build systems, we need to look for them using cc.has_header() and
cc.find_library(), namely for Cairo and HarfBuzz, if one does not have
crafted pkg-config files for them (which, by themselves may be
error-prone).
As a result, we will still try to look for Cairo and HarfBuzz using
pkg-config, but will give another shot at them on Visual Studio using
cc.has_header() and cc.find_library() if they couldn't be found via
pkg-config.
https://bugzilla.gnome.org/show_bug.cgi?id=785210
The Vulkan .lib file that is supplied by the LunarG Vulkan SDK is
vulkan-1.lib, not vulkan.lib, so make sure we look for the right
libraries when building on Visual Studio (I am not sure whether the
LunarG SDK will work for MinGW/mingw-w64 builds, as only Visual Studio
.lib files are provided).
Note that this will require one to set LIB and INCLUDE appropriately to
find the Vulkan .lib and header files, and possibly PATH if one's video
drivers do not contain the Vulkan runtime DLL.
https://bugzilla.gnome.org/show_bug.cgi?id=785210
This is meant to cut down build time in flatpak and similar
situations. Since it produces technically incomplete builds,
we list these options in the status output at the end of
the meson run.
