This adds GLFW_CONTEXT_DEBUG as a preferred alias for
the GLFW_OPENGL_DEBUG_CONTEXT window hint, as debug contexts are
defined for both OpenGL and OpenGL ES.
Related to #1720.
Re-worded documentation for the `GLFW_OPENGL_DEBUG_CONTEXT` window hint
to avoid implying that it only applies to OpenGL contexts. Added a link
to the relevant Khronos extension description.
Closes#1720.
This adds support for EGL_EXT_platform_base and its associated X11 and
Wayland extensions, allowing us to explicitly tell EGL which window
system we are using.
This is based on work by @linkmauve in #1691.
Closes#1691.
This fixes a regression introduced by
105cf32e0b where GLFW_INCLUDE_GLU had no
effect if the GLFW header detected an earlier OpenGL header or loader
library header.
Closes#1712.
This makes the null platform behave more like an actual stub. More
queryable state is tracked and there is even a fake monitor with one
whole fake video mode.
This fixes a race between the key repeat logic and the surface leave
event handler, which could result in repeated keys being reported with
a window of NULL.
Fixes#1704.
The documentation claims that any extension loader library header
included before the GLFW one will prevent the inclusion of the
default OpenGL header. In reality this only worked if the loader
defined the canonical desktop OpenGL __gl_h_ inclusion guard and even
then relied on the OpenGL header to detect this.
This is the companion to 105cf32e0b, which
added the preprocessor logic to check for many known OpenGL and OpenGL
ES inclusion guards and not even attempt to include the default header
if any are present.
Some clarification of the language around header inclusion has also been
attempted, including making GLFW_INCLUDE_NONE more prominent.
Fixes#1695.
This adds two new error codes: GLFW_FEATURE_UNAVAILABLE for when
a GLFW feature cannot be reasonably implemented on that platform, and
GLFW_FEATURE_UNIMPLEMENTED for when it can be but has not been yet.
This replaces the current situation where the Wayland code emitted
GLFW_PLATFORM_ERROR in both cases while the macOS code silently did
nothing.
If your application exits on any GLFW error, these error codes should at
least be easy to filter out from that behavior.
Ideally, GLFW_FEATURE_UNAVAILABLE should be rare and
GLFW_FEATURE_UNIMPLEMENTED should never be emitted at all.
Fixes#1692.
If an OpenGL ES header or the glcorearb header is included before the
GLFW header (with no options defined), the legacy OpenGL header will be
implicitly included and the compilation will fail.
This disables the default behavior if we detect any known OpenGL, OpenGL
ES or extension loader inclusion guard macro.

These are harmless errors but the code was worth fixing just to reduce
confusion and be more explicit. E.g. using a different variable name
for a new variable of a different type in win32_joystick.c.
Closes#1700.
When compiling with `-Wall` and `-pedantic-errors`, gcc complains with
```
warning: ISO C does not support the '%m' gnu_printf format [-Wformat=]
```
because the `%m` conversion specifier is a GNU extension.
Closes#1702.
The only two EGL implementations on macOS are Swiftshader and ANGLE.
While Swiftshader supports both `NSView` and `CALayer` as
`EGLNativeWindowType`, ANGLE supports only `CALayer`. Furthermore
Swiftshader's OpenGL ES frontend is deprecated in favor of using ANGLE's
Vulkan backend on top of Swiftshader's Vulkan frontend.
This means that on macOS `EGLNativeWindowType` should be a `CALayer` for
compatibility with ANGLE.
Fixes#1169.
Closes#1680.
A regression introduced by b889aa7841
broke the special handling of numpad keys for the non-XKB fallback path.
The non-functional remains were later removed. This restores the
original behavior.
