remux

remux

remux is an app switcher for the remarkable tablet. once its running, hold the middle button down for several seconds until the remux launcher appears or swipe up either side of the screen.

Adding Apps

usually, most people install toltec and the apps in toltec all use draft format and are installed into /opt/etc/draft.

but if you are writing a new app or trying out an unpackaged app, there are a few ways to configure the list of apps that appear in remux:

1. via code configuration - edit config.launcher.cpy and recompile remux
2. add a binary to /home/root/apps on the remarkable and make sure it is chmod +x
3. using draft remarkable configuration files. they are installed into /opt/etc/draft

Launching

The built in ways of launching remux are:

• holding home button
• swiping up on either side of the display

if you want to adjust them, they can be changed - see the config section below.

Known issues

• remux restarts xochitl at first launch, it is not crashing
• remux does not show itself after an app exits, you must activate it
• after dismissing remux UI, you need to tap the touch screen before swiping again to show remux
• if you can not swipe in xochitl, try swiping with four fingers to reset xochitl's gesture engine

Building

run make remux from the root dir of rmkit to build it. then run make install_remux to copy remux to the remarkable. Run make run_remux to run remux.

Finally, if you want to make the installation permanent, change into the src/remux directory and run make install_service followed by make start_service

Changelog

Custom start application (0.1.9)

• added start_app= option to specify the app to launch. it can be blank or an app name as seen in the list of apps. if the app isn't found or its blank, no app will launch at startup and remux will require a gesture to be invoked.

Disable Power Management (0.1.8)

• added manage_power= boolean option to configuration. setting to false or no tells remux to not enter suspend mode automatically - this lets you use xochitl solely for power management. useful if remux is messing up drawing your suspend screen

Config (0.1.7)

As of remux 0.1.7, remux supports configuration kept in /home/root/.config/remux/remux.conf. The configuration is kept as key=value lines. As of right now, the two main config options are launch_gesture and back_gesture. They can be used to configure the gestures in remux. The format is the same as genie, except semi-colons (;) are used to separate directives instead of newlines.

For example, the below will show remux when three fingers are tapped and switch to last app on a four finger tap.

launch_gesture=gesture=tap;fingers=3
back_gesture=gesture=tap;fingers=4

You can repeat a key in order to setup multiple gestures for the same action, like so:

launch_gesture=gesture=tap;fingers=3
launch_gesture=gesture=tap;fingers=4

API (0.1.6)

remux opens /run/remux.api as a FIFO and listens for incoming commands. The supported commands are show, hide, and back.

Using the API and genie, one can setup their own gestures for remux. To disable the built in gestures in remux, set launch_gesture=, then verify that no gestures were created in remux's output.
