sas: simple app script
simple is a simple app script for remarkable that lets developers write apps without needing to compile code.
simple app script applies the unix philosophy of pipes to building a UI: a description of the UI to display is provided on stdin and when there is an event on a widget, it prints the UI’s current state and the event to stdout and exits.
using simple app script greatly reduces the amount of code needed to put a UI on the screen and reduces the development lifecycle for developers, since you can immediately re-run your app and see the changes without waiting for the compilation cycle.
the spec is just a spec - the backend for the language can be
written with qt, rust or plain c/cpp. currently, simple is provded as an implementation
of the SAS spec.
an example layout:
button 50 50 200 50 I'm a button
button 50 150 400 50 I'm a different button
label 50 100 300 50 I'm some text
image 50 200 200 200 /home/root/bomb-solid.png
[paragraph 80 450 800 200 I'm multi-line text, I'm multi-line text, I'm
multi-line text, I'm multi-line text, I'm multi-line text, I'm multi-line text,
I'm multi-line text, I'm multi-line text, I'm multi-line text, I'm multi-line
text, I'm multi-line text, I'm multi-line text, I'm multi-line text, I'm
multi-line text, I'm multi-line text, I'm multi-line text,]
an example bash program with one scene and one event:
#!/usr/bin/env sh
while true; do
app="
button 50 50 200 50 option 1
button 250 50 200 50 option 2
label 500 500 200 50 you pressed: ${option}
[paragraph 500 600 500 500 ${output}]
"
echo "APP IS"
echo "${app}"
option=`echo "${app}" | apps/simple.exe | grep 'selected:' | sed 's/selected: //'`
output=`cat /etc/os-release`
sleep 0.1
done
