 ## OS Support

-Most current desktop environments and operating systems are fully supported, this includes
- GNOME >= 45
- KDE Plasma >= 6.1
- Most wlroots based compositors, including Sway (>= 1.8), Hyprland and Wayfire
- Windows
- MacOS
+The following table shows support for input emulation (to emulate events received from other clients) and
+input capture (to send events *to* other clients) on different operating systems:

+| Backend                   | input emulation          | input capture                        |
+|---------------------------|--------------------------|--------------------------------------|
+| Wayland (wlroots)         | :heavy_check_mark:       | :heavy_check_mark:                   |
+| Wayland (KDE)             | :heavy_check_mark:       | :heavy_check_mark:                   |
+| Wayland (Gnome)           | :heavy_check_mark:       | WIP                                  |
+| X11                       | :heavy_check_mark:       | WIP                                  |
+| Windows                   | :heavy_check_mark:       | WIP                                  |

-### Caveats / Known Issues
+Keycode translation is not yet implemented so on MacOS only mouse emulation works as of right now.

-> [!Important]
-> - **X11** currently only has support for input emulation, i.e. can only be used on the receiving end.
->
-> - **Sway / wlroots**: Wlroots based compositors without libei support on the receiving end currently do not handle modifier events on the client side.
-> This results in CTRL / SHIFT / ALT / SUPER keys not working with a sending device that is NOT using the `layer-shell` backend
->
-> - **Wayfire**: If you are using [Wayfire](https://github.com/WayfireWM/wayfire), make sure to use a recent version (must be newer than October 23rd) and **add `shortcuts-inhibit` to the list of plugins in your wayfire config!**
-> Otherwise input capture will not work.
->
-> - **Windows**: The mouse cursor will be invisible when sending input to a Windows system if
-> there is no real mouse connected to the machine.

 ## Usage
-<details>
-    <summary>Gtk Frontend</summary>
-
+### Gtk Frontend
 By default the gtk frontend will open when running `lan-mouse`.

-To connect a device you want to control, simply click the `Add` button and enter the hostname
-of the device.
+To add a new connection, simply click the `Add` button on *both* devices,
+enter the corresponding hostname and activate it.

-On the *remote* device, authorize your *local* device for incoming traffic using the `Authorize` button
-under the "Incoming Connections" section.
-The fingerprint for authorization can be found under the general section of your *local* device.
-It is of the form "aa:bb:cc:..."
+If the mouse can not be moved onto a device, make sure you have port `4242` (or the one selected)
+opened up in your firewall.

-Authorized devices can be persisted using the configuration file (see [Configuration](#configuration)).
+### Command Line Interface
+The cli interface can be enabled using `--frontend cli` as commandline arguments.
+Type `help` to list the available commands.

-If the device still can not be entered, make sure you have UDP port `4242` (or the one selected) opened up in your firewall.
-</details>
-
-<details>
-    <summary>Command Line Interface</summary>
-
-The cli interface can be accessed by passing `cli` as a commandline argument.
-Use
+E.g.:
 ```sh
-lan-mouse cli help
-```
- to list the available commands and
-```sh
-lan-mouse cli <cmd> help
-```
-for information on how to use a specific command.
-
-</details>
-
-<details>
-    <summary>Daemon Mode</summary>
-
-Lan Mouse can be launched in daemon mode to keep it running in the background (e.g. for use in a systemd-service).
-
-To do so, use the `daemon` subcommand:
-
-```sh
-lan-mouse daemon
+$ cargo run --release -- --frontend cli
+(...)
+> connect <host> left|right|top|bottom
+(...)
+> list
+(...)
+> activate 0
 ```

-In order to start lan-mouse with a graphical session automatically,
-the [systemd-service](service/lan-mouse.service) can be used:
-
-Copy the file to `~/.config/systemd/user/` and enable the service:
+### Daemon
+Lan Mouse can be launched in daemon mode to keep it running in the background.
+To do so, add `--daemon` to the commandline args:

 ```sh

-systemctl --user daemon-reload
-systemctl --user enable --now lan-mouse.service
+$ cargo run --release -- --daemon
 ```

+## Protocol
+Currently *all* mouse and keyboard events are sent via **UDP** for performance reasons.
+Each event is sent as one single datagram, currently without any acknowledgement to guarantee 0% packet loss.
+This means, any packet that is lost results in a discarded mouse / key event, which is ignored for now.
+
+**UDP** also has the additional benefit that no reconnection logic is required.
+Any client can just go offline and it will simply start working again as soon as it comes back online.
+
+Additionally a tcp server is hosted for data that needs to be sent reliably (e.g. the keymap from the server or clipboard contents in the future) can be requested via a tcp connection.
+
+## Bandwidth considerations
+The most bandwidth is taken up by mouse events. A typical office mouse has a polling rate of 125Hz
+while gaming mice typically have a much higher polling rate of 1000Hz.
+A mouse Event consists of 21 Bytes:
+- 1 Byte for the event type enum,
+- 4 Bytes (u32) for the timestamp,
+- 8 Bytes (f64) for dx,
+- 8 Bytes (f64) for dy.
+
+Additionally the IP header with 20 Bytes and the udp header with 8 Bytes take up another 28 Byte.
+So in total there is 49 * 1000 Bytes/s for a 1000Hz gaming mouse.
+This makes for a bandwidth requirement of 392 kbit/s in total _even_ for a high end gaming mouse.
+So bandwidth is a non-issue.
+
+Larger data chunks, like the keymap are offered by the server via tcp listening on the same port.
+This way we dont need to implement any congestion control and leave this up to tcp.
+In the future this can be used for e.g. clipboard contents as well.
+
+## Packets per Second
+While on LAN the performance is great,
+some WIFI cards seem to struggle with the amount of packets per second,
+particularly on high-end gaming mice with 1000Hz+ polling rates.
+
+The plan is to implement a way of accumulating packets and sending them as
+one single key event to reduce the packet rate (basically reducing the polling
+rate artificially).
+
+The way movement data is currently sent is also quite wasteful since even a 16bit integer
+is likely enough to represent even the fastest possible mouse movement.
+A different encoding that is more efficient for smaller values like
+[Protocol Buffers](https://protobuf.dev/programming-guides/encoding/)
+would be a better choice for the future and could also help for WIFI connections.

+## Security
+Sending key and mouse event data over the local network might not be the biggest security concern but in any public network or business environment it's *QUITE* a problem to basically broadcast your keystrokes.
+- There should be an encryption layer below the application to enable a secure link.
+- The encryption keys could be generated by the graphical frontend.


-## Detailed OS Support
+## Wayland support
+### Input Emulation (for receiving events)
+On wayland input-emulation is in an early/unstable state as of writing this.

-In order to use a device for sending events, an **input-capture** backend is required, while receiving events requires
-a supported **input-emulation** *and* **input-capture** backend.
+For this reason a suitable backend is chosen based on the active desktop environment / compositor.

-A suitable backend is chosen automatically based on the active desktop environment / compositor.
+Different compositors have different ways of enabling input emulation:

-The following sections detail the emulation and capture backends provided by lan-mouse and their support in desktop environments / operating systems.
+#### Wlroots
+Most wlroots-based compositors like Hyprland and Sway support the following
+unstable wayland protocols for keyboard and mouse emulation:
+- [virtual-keyboard-unstable-v1](https://wayland.app/protocols/virtual-keyboard-unstable-v1)
+- [wlr-virtual-pointer-unstable-v1](https://wayland.app/protocols/wlr-virtual-pointer-unstable-v1)

-### Input Emulation Support
+#### KDE
+KDE also has a protocol for input emulation ([kde-fake-input](https://wayland.app/protocols/kde-fake-input)),
+it is however not exposed to third party applications.

+The recommended way to emulate input on KDE is the
+[freedesktop remote-desktop-portal](https://flatpak.github.io/xdg-desktop-portal/#gdbus-org.freedesktop.portal.RemoteDesktop).

- `wlroots`: This backend makes use of the [wlr-virtual-pointer-unstable-v1](https://wayland.app/protocols/wlr-virtual-pointer-unstable-v1) and [virtual-keyboard-unstable-v1](https://wayland.app/protocols/virtual-keyboard-unstable-v1) protocols and is supported by most wlroots based compositors.
- `libei`: This backend uses [libei](https://gitlab.freedesktop.org/libinput/libei) and is supported by GNOME >= 45 or KDE Plasma >= 6.1.
- `xdp`: This backend uses the [freedesktop remote-desktop-portal](https://flatpak.github.io/xdg-desktop-portal/#gdbus-org.freedesktop.portal.RemoteDesktop) and is supported on GNOME and Plasma.
- `x11`: Backend for X11 sessions.
- `windows`: Backend for Windows.
- `macos`: Backend for MacOS.
+#### Gnome
+Gnome uses [libei](https://gitlab.freedesktop.org/libinput/libei) for input emulation and capture,
+which has the goal to become the general approach for emulating and capturing Input on Wayland.

+### Input capture

+To capture mouse and keyboard input, a few things are necessary:
+- Displaying an immovable surface at screen edges
+- Locking the mouse in place
+- (optionally but highly recommended) reading unaccelerated mouse input

-### Input Capture Support

+The [zwlr\_virtual\_pointer\_manager\_v1](wlr-virtual-pointer-unstable-v1) is required
+to display surfaces on screen edges and used to display the immovable window on
+both wlroots based compositors and KDE.
+
+Gnome unfortunately does not support this protocol
+and [likely won't ever support it](https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/1141).
+
+~In order for layershell surfaces to be able to lock the pointer using the pointer\_constraints protocol [this patch](https://github.com/swaywm/sway/pull/7178) needs to be applied to sway.~
+(this works natively on sway versions >= 1.8)

- `layer-shell`: This backend creates a single pixel wide window on the edges of Displays to capture the cursor using the [layer-shell protocol](https://wayland.app/protocols/wlr-layer-shell-unstable-v1).
- `libei`: This backend uses [libei](https://gitlab.freedesktop.org/libinput/libei) and is supported by GNOME >= 45 or KDE Plasma >= 6.1.
- `windows`: Backend for input capture on Windows.
- `macos`: Backend for input capture on MacOS.
- `x11`: TODO (not yet supported)
