Collection of reMarkable related apps, utilities and libraries.
All of this was done by Claude, Codex and me (5%). Look into docs folder for very detailed description.
Tested on Remarkable 2 firmware 3.3.2.1666 with Toltec installed.
Clone repo and run:
./scripts/test-fonts.sh
to build following variants of yaft:
Font variants (all Polish support — żółćęśąźń ŻÓŁĆĘŚĄŹŃ):
| Binary | Cell size | Cols × Rows (rM2 1404×1872) |
|---|---|---|
yaft-terminus-16x32 |
16×32 | 87 × 58 (original, small) |
yaft-terminus-24x48 |
24×48 | 58 × 39 ★ recommended |
yaft-terminus-28x56 |
28×56 | 50 × 33 |
yaft-terminus-32x64 |
32×64 | 43 × 29 |
yaft-spleen-16x32 |
16×32 | 87 × 58 |
yaft-spleen-32x64 |
32×64 | 43 × 29 (currently deployed) |
Build will use Docker for crosscompiling, image is ~1.7GB so delete it after use.
Transfer them to your Remarkable2, e.g:
scp build/font-test/yaft-terminus-24x48 root@10.11.99.1:/home/root/
I use remux launcher.
Create a file in /opt/etc/draft/yaft-24x48.draft with following content:
name=yaft-24x48
desc=Framebuffer terminal emulator with bigger font
call=/opt/bin/yaft-terminus-24x48
term=:
imgFile=yaft
Bring remux menu with gesture and you will see 'yaft-24x48' item, select it to run.
Polish characters are available on Folio with RightAlt+letter, e.g. ą - RightAlt+a.
Custom implementation for reMarkable 2 framebuffer. The differences are:
- Lower level hooking, removing the Qt dependence.
- Uses UNIX sockets instead of message queues. Makes it easier to implement synchronized updates.
- Supports less but newer xochitl versions
A fast framebuffer terminal emulator.
To use simply execute yaft or yaft <command..>.
More usage information can be found in the yaft Readme.
Launcher that uses the power button to show.
When pressing the power button, the app drawer will be shown with a timeout of 10 seconds.
After 10 seconds the device will go to sleep, unless an app is picked before that timeout.
You can also interrupt the timeout by pressing the [x] button.
This allows you to switch apps without relying on gestures.
A TI-84+ calculator emulator for the remarkable.
To use simply execute tilem, a prompt for downloading a ROM file will be shown.
If you already have a ROM file, you can pass it as an argument on the command line.
Library for writing remarkable apps. Includes an extensive declarative UI framework based on Flutter.
A NixOS module that allows soft-rebooting into NixOS. This allows to declaratively manage your reMarkable 2 configuration.
This lib contains a reverse engineered software TCON. It currently still relies
on some functions from xochitl, namely the generator thread routine.
To use these functions it must be launched as an LD_PRELOAD library attached to xochitl.
The swtcon-preload tool is an example of how it can be currently used.
Building for the remarkable can either use the toltec toolchain or the reMarkable one:
# For toltec:
$ cmake --preset dev-toltec
# For remarkable:
$ cmake --preset dev
# To build everything:
$ cmake --build build/dev
# Or to build a specific app:
$ cmake --build build/dev --target yaft
# To create an ipk file:
$ cmake --build build/dev --target packageFor faster development an EMULATE mode is supported by rMlib. This allows
running most apps on a desktop using SDL to emulate the remarkable screen.
To enable it pass -DEMULATE=ON to the cmake configure command, without using
the reMarkable toolchain of course.
$ cmake --preset dev-host
$ cmake --build build/host --target yaft
$ ./build/host/apps/yaft/yaft # Should launch Yaft with an emulated screen in a separete window.
