pi uses [Fyne](https://fyne.io) for the frontend and uses the [Oasis SDK](https://github.com/jjj333-p/oasis-sdk) by [Joseph Winkie](https://pain.agency) for XMPP functionality.
pi is an extremely opinionated client. It aims to have as little extra windows as possible, instead using alt-menus to perform many of the actions you'd see in a typical client.
When you launch pi, you will be greeted with a create account screen. You will then be able to enter your XMPP account details and then relaunch the application to log in.
You will need to add ~/Go/bin to your $PATH, for MSYS2 you can paste the following command into your terminal:
$ echo "export PATH=\$PATH:~/Go/bin" >> ~/.bashrc
For the compiler to work on other terminals you will need to set up the windows %PATH% variable to find these tools. Go to the “Edit the system environment variables” control panel, tap “Advanced” and add “C:\msys64\mingw64\bin” to the Path list.
On BSD and Linux systems, you may want to build an executable for Wayland only, meaning it will not run through XWayland. This will increase performance and also allow drag-on-drop functionality. Most Wayland setups can run X11 apps, but no X11 setup can run Wayland apps. Because of this, all executables are shipped for use with X11. This may change in the future, but if you want to build for Wayland, it's as simple as the commands above, but just adding a `wayland` tag to the build command.
A Wayland-only executable will also substantially decrease the level of screen tearing and lag.
pi currently has no consolidated way of installing it. There is an [Arch User Repository package available](https://aur.archlinux.org/pi-im), which is maintained by [snit](https://isekai.rocks/~snit).
Pi will require no additional dependencies to run on MacOS and Windows systems.
On other *NIX systems, `dbus` is needed for notification support, but is not required.
If your system has an X11 or Wayland setup, Pi will most likely work without issues.
Pi does not require GTK, Qt or any other graphical layout.
### Compiling
In general, you need Go, a C compiler and graphical libraries.
*This information is from the [https://docs.fyne.io/started/](the Fyne documentation.) Windows and MacOS users are heavily reccomended to simply use pre-compiled binaries, due a more complex set of dependencies.*
Linux systems:
Debian, Ubuntu and Raspberry Pi OS: `sudo apt-get install golang gcc libgl1-mesa-dev xorg-dev libxkbcommon-dev`
[1] Android is not a supported platform, however it's possible to compile and run pi for it. If you want to become suicidal, you can go for it, but pi is a primarily PC-oriented client. There are multiple mobile clients that already exist which will give you a substantially better experience.
