[Bin] Huge simplification of wacom-setup
It’s not a one-liner yet, but it’s still much shorter and cleaner than the previous mess. Also change wacom-setup from a fish script to a sh script

I made a small and quick utility to set up my Wacom tablet so it is
|
||||
only bound to one screen. This is quite easy, we simply need to find
|
||||
the Wacom stylus’ ID and assign it to the display we want.

||||

||||

:END:
|
||||
We need some variables in order to correctly set our tablet. First, let’s get
|
||||
declare what the name of our tablet is, and what the name of its touchpad is.
|
||||
#+BEGIN_SRC fish
|
||||
set -g DEVICE "Wacom USB Bamboo PAD Pen stylus"
|
||||
#+END_SRC
|
||||
|
||||
To get the correct values for the area it can cover, we’ll need to reset our
|
||||
tablet.
|
||||
#+BEGIN_SRC fish
|
||||
xsetwacom set "$DEVICE" ResetArea
|
||||
#+END_SRC
|
||||
|
||||
Now we can get the X and Y areas.
|
||||
#+BEGIN_SRC fish
|
||||
set -g AREATOT (xsetwacom get "$DEVICE" Area)
|
||||
set -g AREAX (echo $AREATOT | awk '{print $3}')
|
||||
set -g AREAY (echo $AREATOT | awk '{print $4}')
|
||||
#+END_SRC
|
||||
|
||||
*** Select our screen

|
||||
:END:
|
||||
This function will allow us to select the screen on which the tablet will be
|
||||
active. We can also select the option “desktop” so that all screens are
|
||||
selected. Let’s declare our function.
|
||||
#+BEGIN_SRC fish :noweb yes
|
||||
function set_screen
|
||||
<<wacom-screen-get-displays>>
|
||||
<<wacom-screens-select-screen>>
|
||||
<<wacom-screen-get-position>>
|
||||
<<wacom-screen-get-dimensions>>
|
||||
end
|
||||
#+END_SRC
|
||||
|
||||
First, let’s set what screens are available, including the desktop option.
|
||||
#+NAME: wacom-screen-get-displays
|
||||
#+BEGIN_SRC fish :tangle no
|
||||
set CONNECTED_DISPLAYS (xrandr -q --current | \
|
||||
sed -n 's/^\([^ ]\+\) connected .*/\1/p') desktop
|
||||
#+END_SRC
|
||||
|
||||
Now, let’s select the one we wish to use using rofi.
|
||||
#+NAME: wacom-screens-select-screen
|
||||
#+BEGIN_SRC fish :tangle no
|
||||
set -g SCREEN (for d in $CONNECTED_DISPLAYS
|
||||
echo $d
|
||||
end | rofi -dmenu -i -p "Select your dispaly" | tr -d '\n')
|
||||
#+END_SRC
|
||||
|
||||
We can now get the position of our screen.
|
||||
#+NAME: wacom-screen-get-position
|
||||
#+BEGIN_SRC fish :tangle no
|
||||
set -g POSITION (xrandr -q --current | sed -nr "s/^$SCREEN connected (primary )*([0-9x\+]+).*/\2/p")
|
||||
#+END_SRC
|
||||
|
||||
We’ll also get the width and height of the screen so we can set correctly the
|
||||
drawing area of the tablet.
|
||||
#+NAME: wacom-screen-get-dimensions
|
||||
#+BEGIN_SRC fish :tangle no
|
||||
set -g HEIGHT (echo $POSITION | sed -nr 's/[0-9]+x([0-9]+).*/\1/p')
|
||||
set -g WIDTH (echo $POSITION | sed -nr 's/([0-9]+)x.*/\1/p')
|
||||
#+END_SRC
|
||||
|
||||
*** Adjust the tablet
|
||||
:PROPERTIES:
|
||||
:CUSTOM_ID: Wacom_setup-Adjust_the_tablet-342acaf3
|
||||
:END:
|
||||
This function will take care of adjusting our tablet to our screen. Let’s
|
||||
declare our function.
|
||||
#+BEGIN_SRC fish :noweb yes
|
||||
function adjust_device
|
||||
<<wacom-tablet-set-ration-area>>
|
||||
<<wacom-tablet-set-new-area>>
|
||||
<<wacom-tablet-set-device-area-and-screen>>
|
||||
end
|
||||
#+END_SRC
|
||||
|
||||
If our screen is too high or too wide for our tablet, we will have to adjust the
|
||||
height or width of the area used by the tablet. So let’s get the theoretical new
|
||||
height and width of the area.
|
||||
#+NAME: wacom-tablet-set-ration-area
|
||||
#+BEGIN_SRC fish :tangle no
|
||||
set RATIOAREAY (math ceil \($AREAX \* $HEIGHT \/ $WIDTH\))
|
||||
set RATIOAREAX (math ceil \($AREAY \* $WIDTH \/ $HEIGHT\))
|
||||
#+END_SRC
|
||||
|
||||
Now, if the current height of the tablet’s area is greater than the theoretical
|
||||
new area, it means the current area is too high. Otherwise, it should be the
|
||||
other way around. Let’s set =NEWAREAX= and =NEWAREAY= that will be used to set
|
||||
the new area for the tablet.
|
||||
#+NAME: wacom-tablet-set-new-area
|
||||
#+BEGIN_SRC fish :tangle no
|
||||
if test $AREAY -gt $RATIOAREAY
|
||||
set -g NEWAREAX $AREAX
|
||||
set -g NEWAREAY $RATIOAREAY
|
||||
else
|
||||
set -g NEWAREAX $RATIOAREAX
|
||||
set -g NEWAREAY $AREAY
|
||||
end
|
||||
#+END_SRC
|
||||
|
||||
Alright, now let’s set the new area with these new variables.
|
||||
#+NAME: wacom-tablet-set-device-area-and-screen
|
||||
#+BEGIN_SRC fish :tangle no
|
||||
xsetwacom set "$DEVICE" Area 0 0 $NEWAREAX $NEWAREAY
|
||||
#+END_SRC
|
||||
|
||||

|

:END:
|
||||
Back to the main body of the script, we can now launch the functions
|
||||
sequencially.
|
||||
#+BEGIN_SRC fish
|
||||

|
