I had forgotten that Cmd_Args() preserves quotes, which resulted in
button bindings having excess quotes when used to bind complex commands
(eg, the default quicksave and quickload bindings).
keyhelp provides the input name if it is known, and in_bind tries to use
the provided input name if not a number. Case sensitivity for name
lookups is dependent on the input driver.
There's now an internal event handler for taking care of device addition
and removal, and a public event handler for dealing with device input
events in various contexts In particular, so the clients can check for
the escape key.
While the console command line is quite good for setting everything up,
the devices being bound do need to be present when the commands are
executed (due to needing extra data provided by the devices). Thus
property lists that store the extra data (button and axis counts, device
names/ids, connection names, etc) seems to be the best solution.
Recipes themselves still use float, but using double in the cexpr values
allows bare floating point numbers (which parse as double) to be used,
making the bind command line a little more user-friendly.
The mouse bound to movement axes works (though signs are all over the
place, so movement direction is a little off), and binding F10 (key 68)
to quit works :)
Each axis binding has its own recipe (meaning the same input axis can be
interpreted differently for each binding)
Recipes are specified with field=value pairs after the axis name.
Valid fields are minzone, maxzone, deadzone, curve and scale, with
deadzone doubling as a balanced/unbalanced flag.
The default recipe has no zones, is balanced, and curve and scale are 1.
Hot-plug support is done via "connections" (not sure I'm happy with the
name) that provide a user specifiable name to input devices. The
connections record the device name (eg, "6d spacemouse") and id (usually
usb path for evdev devices, but may be the device unique id if
available) and whether automatic reconnection should match just the
device name or both device name and id (prevents problems with changing
the device connected to the one usb port).
in_bind is only partially implemented (waiting on imt), but device
listing, device naming, and input identification are working. The event
handling system made for a fairly clean implementation for input
identification thanks to the focused event handling.
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).
Input Mapping Tables are still at the core as they are a good concept,
however they include both axis and button mappings, and the size is not
hard-coded, but dependent on the known devices. Not much actually works
yet (nq segfaults when a key is pressed).
