## Build and Run
## Installation
### Install Dependencies
#### Macos
### Download from Releases
The easiest way to install Lan Mouse is to download precompiled release binaries from the [releases section](https://github.com/feschber/lan-mouse/releases).
For Windows, the depenedencies are included in the .zip file, for other operating systems see [Installing Dependencies](#installing-dependencies).
### Arch Linux
Lan Mouse is available on the AUR:
```sh
brew install libadwaita
# git version (includes latest changes)
paru -S lan-mouse-git
# alternatively
paru -S lan-mouse-bin
```
#### Ubuntu and derivatives
```sh
sudo apt install libadwaita-1-dev libgtk-4-dev libx11-dev libxtst-dev
```
### Nix
- nixpkgs: [search.nixos.org](https://search.nixos.org/packages?channel=unstable&show=lan-mouse&from=0&size=50&sort=relevance&type=packages&query=lan-mouse)
- flake: [README.md](./nix/README.md)
#### Arch and derivatives
```sh
sudo pacman -S libadwaita gtk libx11 libxtst
```
#### Fedora and derivatives
```sh
sudo dnf install libadwaita-devel libXtst-devel libX11-devel
```
### Building from Source
#### Windows
Follow the instructions at [gtk-rs.org](https://gtk-rs.org/gtk4-rs/stable/latest/book/installation_windows.html)
*TLDR:*
Build gtk from source
- The following commands should be run in an admin power shell instance:
```sh
# install chocolatey
Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))
# install python 3.11 (Version is important, as 3.12 does not work currently)
choco install python --version=3.11.0
# install git
choco install git
# install msys2
choco install msys2
# install Visual Studio 2022
choco install visualstudio2022-workload-vctools
```
- The following commands should be run in a regular power shell instance:
```sh
# install gvsbuild with python
python -m pip install --user pipx
python -m pipx ensurepath
pipx install gvsbuild
# build gtk + libadwaita
gvsbuild build gtk4 libadwaita librsvg
```
Make sure to add the directory `C:\gtk-build\gtk\x64\release\bin`
[to the `PATH` environment variable]((https://learn.microsoft.com/en-us/previous-versions/office/developer/sharepoint-2010/ee537574(v=office.14))). Otherwise the project will fail to build.
To avoid building GTK from source, it is possible to disable
the gtk frontend (see conditional compilation below).
### Build and run
Build in release mode:

cargo build --release

To avoid building GTK from source, it is possible to disable
the gtk frontend (see conditional compilation below).
## Usage
### Gtk Frontend
By default the gtk frontend will open when running `lan-mouse`.

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:

cp service/lan-mouse.service ~/.config/systemd/user
systemctl --user daemon-reload
systemctl --user enable --now lan-mouse.service

Lan Mouse is a mouse and keyboard sharing software similar to universal-control on Apple devices. It allows for using multiple pcs with a single set of mouse and keyboard. This is also known as a Software KVM switch.
The primary target is Wayland on Linux but Windows and MacOS and Linux on Xorg have partial support as well (see below for more details).
