## Whiteboard HyperCard ~ live collaboration/drawing/chat/whiteboarding



Easiest installation through [toltec's `opkg`](https://github.com/toltec-dev/toltec)

```

opkg update && opkg install whiteboard-hypercard

```



### Self-hosting whiteboard-server / hosting private rooms



On a machine with IP `1.2.3.4` reachable over the Internet, run:

```

git clone https://github.com/fenollp/reMarkable-tools.git && cd reMarkable-tools && make debug

```

Now on your tablet, run the `whiteboard` Rust application with `--host`, as in:

```

export WHITEBOARD_WEBHOST=http://1.2.3.4:10001/screenshare

.../whiteboard --host=http://1.2.3.4:10000

```

Finally, `docker compose` should show you something akin to:

```

## koreader

* https://github.com/koreader/koreader/releases/latest

* instructions: https://github.com/koreader/koreader/wiki/Installation-on-Remarkable

* creates metadata files:

```

find ~ -name '*.sdr'

```



## Tools

* [`cbr2cbz.sh *.cbr`](./cbr2cbz.sh) unrars then zips CBRs into CBZs so `koreader` can open them.

* `rsync` on the tablet:

    1. wget https://raw.githubusercontent.com/Evidlo/remarkable_entware/master/entware_install.sh && chmod +x entware_install.sh

    1. opkg install rsync

    1. And because `ssh remarkable 'echo $PATH' #=> /usr/bin:/bin`

    1. ln -s `which rsync` /usr/bin/



## Attention



### Updates wipe `~`



### root partition is small

```

remarkable: ~/ df -h

Filesystem                Size      Used Available Use% Mounted on

/dev/root               223.0M    175.0M     32.3M  84% /

```

so routinely run

```

journalctl --vacuum-size=2M

```



## HyperCards



Visible rectangular elements that can be drawn on/dragged/zoomed/rotated/connected/duplicated.

* tools / modifiers are square cards snapping to the edges of the screen

	* *henceforth mentioned as `[ToolX]` for tool X*

	* using them / modifying them by a press held while using the pencil

            * similar to Minecraft's mix & match: action through combination

	* a `[?]` tool always hangs in a corner, pressing = shows description text (like crosswords)

	* modification (reorganization / addition / removal) through drawing and pressing

	* tools icons can be drawn too / loaded from a font / loaded from a builtin set of images

	* pen & fingers are different devices for different purposes

	    * => drag/move and pinch/zoom (think Apple trackpad gestures) not a pen thing

* whiteboard card

	* rectangle that can be moved by dragging on the edges

	* zoom/rotation by dragging in the area (not the edges)

		* MIGHT: zooming hard moves to another user's view? --> canvas is a window/camera view that can move in 2+1D

	* some bi-directional communication with a networked service

		* user joins a room and shares their live drawings

		* It is possible to combine a [Selection]-ed group of strokes and [Digitize] to ask service for translation

* `[Digitize]`

	* connects to a distant machine or achieves its AI inference on-tablet

	* takes a few strokes in and outputs text+area / shape+area

* `[Selection]`

	* draw approximately on one or more strokes

	* creates a group that can be used with other modifiers

	* press another tool before unpressing this one to pass the group to the other tool

* `[Image]`

	* add an image to a layer

        * should be able to dim that layer

	* select the tool's image with `[Setter] > [Image]` --> opens image picker

	* image should be draggable + zoomable (= two-finger gesture on iOS Reddit app's image viewer)

        * should be able to draw on top of said image
