This was always a horrible hack just to get the screen centered on the
window back when we were doing fullscreen badly. With my experiments
with XInput, it has proven to be a liability (I'd forgotten it was even
there until it started imposing a 2s delay to QF's startup).
Input driver can now have an optional init_cvars function. This allows
them to create all their cvars before the actual init pass thus avoiding
some initialization order interdependency issues (in this case, fixing a
segfault when starting x11 clients fullscreen due to the in_dga cvar not
existing yet).
Seems to work nicely for keyboard (though key bindings are not
cross-platform). Mouse not tested yet, and I expect there are problems
with it for absolute inputs (yay mouse warp :P).
Mouse axis and button names are handled internally (and thus
case-insensitive).
Key names are handled by X11. Case-sensitivity is currently determined
by Xlib.
The cooked inputs (ie_key, ie_mouse) are intended for UI interaction, so
generally should have priority over the raw events, which are intended
for game interaction.
This has smashed the keydest handling for many things, and bindings, but
seems to be a good start with the new input system: the console in
qw-client-x11 is usable (keyboard-only).
The button and axis values have been removed from the knum_t enum as
mouse events are separate from key events, and other button and axis
inputs will be handled separately.
keys.c has been disabled in the build as it is obsolute (thus much of
the breakage).
I'm undecided on how to handle application focus (probably gain/lose
events), and the destination handler has been a stub for a while. One less
dependency on the "old" key handling code.
I'm undecided if the pasted text should be sent as a string rather than
individual key events, but this will do the job for now as it gets me
closer to being able to test everything.
It seems that under certain circumstances (window managers?), select is not
reliable for getting key events, so use of select has been disabled until I
figure out what's going on and how to fix it.
For the mouse in x11, I'm not sure which is more cooked: deltas or
window-relative coordinates, but I don't imagine that really matters too
much. However, keyboard and mouse events suitable for 2D user interfaces
are sent at the same time as the more game oriented button and axis events.
The x11 keyboard and mouse devices are really core input devices rather
than x11 input devices in that keyboard and mouse will be present on most
systems and thus not specific to the main user interface (x11, windows,
etc).
Now nothing works at all ;) However, that's only because the binding
system is incomplete: the X11 input events are getting through to the
binding system, so now it's just a matter of getting that to work.
The common input code (input outer loop and event handling) has been
moved into libQFinput, and modified to have the concept of input drivers
that are registered by the appropriate system-level code (x11, win,
etc).
As well, my evdev input library code (with hotplug support) has been
added, but is not yet fully functional. However, the idea is that it
will be available on all systems that support evdev (Linux, and from
what I've read, FreeBSD).
The recent changes to key handling broke using escape to get out of the
console (escape would toggle between console and menu). Thus take care
of the menu (escape) part of the coupling FIXME by implementing a
callback for the escape key (and removing key_togglemenu) and sorting
out the escape key handling in console. Seems to work nicely
conwidth and conheight have been moved into vid.conview (probably change
the name at some time), and scr_vrect has been replaced by a view as
well. This makes it much easier to create 2d elements that follow the
screen size (taking advantage of a view's gravity) which will, in the
end, make changing the window size easier.
This refactors (as such) keys.c so that it no longer depends on console
or gib, and pulls keys out of video targets. The eventual plan is to
move all high-level general input handling into libQFinput, and probably
low-level (eg, /dev/input handling for joysticks etc on Linux).
Fixes#8
vid.aspect is removed (for now) as it was not really the right idea (I
really didn't know what I was doing at the time). Nicely, this *almost*
fixes the fov bug on fresh installs: the view is now properly
upside-down rather than just flipped vertically (ie, it's now rotated
180 degrees).
Not only does it makes sense to centralize the setting of viewport and
scissor, but it's actually necessary in order to fix the upside-down
rendering on windows.
This gets the GL and GLSL renderers working for the -win targets... sort
of: they are upside down and GLSL's bsp surfaces are black (same as
Vulkan). However, with this, all 5 renderers at least limp along for
-win, 4/5 work for -sdl.
It turns out the dd and dib "driver" code is very specific to the
software renderer. This does not fix the segfault on changing video
mode, but I do know where the problem lies: the window is being
destroyed and recreated without recreating the buffers. I suspect a
clean solution to this will allow for window resizing in X as well.
Only 64-bit windows is tested, and there are still various failures, but
QF is limping along in windows again.
nq-sdl works for sw, and sw32, gl and glsl are mostly black (but not
entirely for gl?), vulkan is not supported with sdl.
nq-win works for sw and sw32, and sort of for vulkan (very dark and
upside-down?). gl and glsl complain about vid mode,
qw-client-[sdl,win] seem to be the same, but something is wrong with the
console (reading keyboard input).
It looks like choosing a visual is not necessary (at least for normal
apps, VR might be another matter). Still no idea if anything works (for
-win support in general, let alone vulkan).
Still "some" more to go: a pile to do with transforms and temporary
entities, and a nasty one with host_cbuf. There's also all the static
block-alloc lists :/
It now takes a context pointer (opaque data) that holds the buffers it
uses for the temporary strings. If the context pointer is null, a static
context is used (making those uses of va NOT thread-safe). Most calls to
va use the static context, but all such calls have been formatted
consistently so they are easy to find when it comes time to do a full
audit.
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.
The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.
Most of the old Makefile.am files are now Makemodule.am. This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases). The current remaining Makefile.am files are for
standalone sub-projects.a
The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.
While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).
They take a pointer to a free-list used for hashlinks so the hashlink
pools can be per-thread. However, hash tables that are not updated are
always thread-safe, so this affects only updates. progs_t has been set
up such that it is easy for multiple progs within one thread can share
hashlinks.
This allows for the four combinations of shift and control. Not
bothering with alt because alt-f4 closes my xterm (bbkeys from the looks
of it: it grabs a bunch of Mod1-* keys).
I added Sys_RegisterShutdown years ago and never really did anything
with it: now any system that needs to be shutdown can ensure it gets
shutdown on program exit, and in the correct order (ie, reverse to init
order).
This makes sure that some unchecked event doesn't cause a lockup.
However, blocking input is really not the way to go: need to implement a
state machine and use non-blocking event reads.
Or really, allow it if the user specifically requests it: the default is
blocked. Modern systems (particularly displays) do not really like
changing resolution, so doing so by default seems rather wrong.

This paves the way for clean initialization of the Vulkan renderer, and
very much cleans up the older renderer initialization code as gl and sw
are no longer intertwined.
This fixes the segfault and pushes things very much in the desired
direction of proper system independence for rendering and presentation
separation (though things were headed in the right direction before).
Also fix a bug where despite supporting 32 buttons, only 18 were actually
supported, and a similar issue for the number of axes.
My saitek x52 has 34 buttons and 10 axes. Whee.
Once and for all: remove the default and move the Sys_Error outside the
switch (changing appropriate breaks to returns). Now gcc will let me know
when I forget to update the switch statements.
Johnny's number->J_AXISn mapping is preserved, but I had intended for any
key to be supported (J_AXISn was just to ensure free keys were available).
This gives both methods (and some range checking on the axis button
number).
