This change adds logic to parse a keyboard layout file, and compile that
into a layout structure that can be used later by the profile to map the
characters into a key+modifiers structure.
Prior to this change, the mouse speed was controlled by an opaque
numeric value, that controlled both the speed and the delay between
updates. This caused a lot of choppy behavior with lower speeds, and the
really low speeds had as little as 1% speed difference between them in
the practical pixels/second speed, while there was effectively a 50%
jump in the speed between speed settings 11 and 12, due to the
hyperbolic relationship between steps. Post that, it was an even 25%
increase in sensitivity for every step.
This change modifies it so that the old Speed option is deprecated, it
is now replaced by the Sensitivity option, which is a direct percentage
scale from 10% to 500%. In addition, there is a CurveFactor option to
let it have fine control when there is little deflection, and move
faster when further away from the center. This also adds an
IsometricMode option which computes the speed as a function of the
cartesian distance from the center (`sqrt(dx^2 + dy^2)`). The default
behavior uses the existing linear speed which controls the speed of the
X and Y axes independently, but now uses the sensitivity and curve
factors to get better behavior. Also, the mouse events are consistently
reported every 10ms. This should make it a lot smoother.
Finally, this change also adds a Deadzone factor, which allows the user
to ignore small changes near the center of the joystick that can cause
mouse drift. This deadzone uses the total distance, so if just the X or
Y axis has moved, it will still allow suppressing any play in the thumb
stick.
Issue: #44
Previously, x52d had conditional compilation flags linking to libevdev
on Linux. However, I wanted to change this so that we use an abstraction
layer that will link to the appropriate backend (evdev on Linux only for
now). The idea is that we get rid of all conditional compilation blocks
and deal with the backend through the vkm library.
This new library handles the mouse scrolling, clicking, as well as
adding the ability to include keyboard events so that we can support the
profiles feature in a future commit.
The change to build using Meson broke the install target, causing x52ctl
and x52d to fail with a missing libx52dcomm library. This was fixed by
setting `install: true` in the library call.
In addition, several features were used that were leftover from my
earlier attempts to migrate to Meson, but targeted older Meson versions.
Some of these features were deprecated in newer Meson versions, and
therefore, cause warnings to show up during meson setup.
GH-Issue: #63
GH-Issue-URL: https://github.com/nirenjan/libx52/issues/63
When enabling --warnlevel=3 during Meson setup, the build threw up
several warnings, mostly related to either unused parameters, or
sometimes an integer type mismatch. This commit addresses all of those
changes and ensures that the build does not contain any unnecessary
warnings.
Prior to this change, the check was for an explicit -Dnls=enabled,
however, if the option was never set, it defaulted to disabled. With
this change, unless explicitly disabled, the Meson build system will
automatically build with NLS support.
Meson is a far more robust build framework, compared to autotools. This
greatly simplifies adding new features, since it's far easier to
maintain a set of meson.build files vs the autotools mishmash.
DEPRECATION NOTICE: Autotools based build is deprecated and will be
removed in the future.
