# niri

|
|
The beginnings of a scrollable-tiling Wayland compositor.
|
|
|

|
## Status
|
|
|
|
Heavily work in progress.
|
|
The occasional thing works, but likely is in a half-broken state.

## Idea
|
|
|
|
This section describes the goals I'm working towards.
|
|
Many things don't work as written yet.
|
|
|
|
Niri implements scrollable tiling, heavily inspired by [PaperWM].
|
|
Windows are arranged in columns on an infinite strip going to the right.
|
|
Every column takes up as much height as possible, spread between its windows.
|
|
|
|
With multiple monitors, every monitor has its own separate window strip.
|
|
Windows can never "overflow" to an adjacent monitor.
|
|
|
|
This is one of the reasons that prompted me to try writing my own compositor.
|
|
PaperWM is a solid implementation that I use every day, but, being a GNOME Shell extension, it has to work around Shell's global window coordinate space to prevent windows from overflowing.
|
|
|
|
Niri also has dynamic workspaces which work similar to GNOME Shell.
|
|
Since windows go left-to-right horizontally, workspaces are arranged vertically.
|
|
Every monitor has an independent set of workspaces, and there's always one empty workspace present all the way down.
|
|
|
|
Niri tries to preserve the workspace arrangement as much as possible upon disconnecting and connecting monitors.
|
|
When a monitor disconnects, its workspaces will move to another monitor, but upon reconnection they will move back to the original monitor where it makes sense.
|
|
|
|
## Running
|
|
|
|
`cargo run -- -- alacritty`
|
|
|
|
Inside a desktop session, it will run in a window.
|
|
On a TTY, it will run natively.
|
|
|
|
To exit when running on a TTY, press <kbd>Super</kbd><kbd>Shift</kbd><kbd>E</kbd>.
|
|
|
|
## Hotkeys
|
|
|
|
When running on a TTY, the Mod key is <kbd>Super</kbd>.
|
|
When running in a window, the Mod key is <kbd>Alt</kbd>.
|
|
|
|
The general system is: if a hotkey switches somewhere, then adding <kbd>Ctrl</kbd> will move the focused window or column there.
|
|
|
|
| Hotkey | Description |
|
|
| ------ | ----------- |
|
|
| <kbd>Mod</kbd><kbd>T</kbd> | Spawn `alacritty` |
|
|
| <kbd>Mod</kbd><kbd>D</kbd> | Spawn `fuzzel` |
|
|
| <kbd>Mod</kbd><kbd>N</kbd> | Spawn `nautilus` |
|
|
| <kbd>Mod</kbd><kbd>Q</kbd> | Close the focused window |
|
|
| <kbd>Mod</kbd><kbd>H</kbd> or <kbd>Mod</kbd><kbd>←</kbd> | Focus the window to the left |
|
|
| <kbd>Mod</kbd><kbd>L</kbd> or <kbd>Mod</kbd><kbd>→</kbd> | Focus the window to the right |
|
|
| <kbd>Mod</kbd><kbd>J</kbd> or <kbd>Mod</kbd><kbd>↓</kbd> | Focus the window below in a column |
|
|
| <kbd>Mod</kbd><kbd>K</kbd> or <kbd>Mod</kbd><kbd>↑</kbd> | Focus the window above in a column |
|
|
| <kbd>Mod</kbd><kbd>Ctrl</kbd><kbd>H</kbd> or <kbd>Mod</kbd><kbd>Ctrl</kbd><kbd>←</kbd> | Move the focused column to the left |
|
|
| <kbd>Mod</kbd><kbd>Ctrl</kbd><kbd>L</kbd> or <kbd>Mod</kbd><kbd>Ctrl</kbd><kbd>→</kbd> | Move the focused column to the right |
|
|
| <kbd>Mod</kbd><kbd>Ctrl</kbd><kbd>J</kbd> or <kbd>Mod</kbd><kbd>Ctrl</kbd><kbd>↓</kbd> | Move the focused window below in a column |
|
|
| <kbd>Mod</kbd><kbd>Ctrl</kbd><kbd>K</kbd> or <kbd>Mod</kbd><kbd>Ctrl</kbd><kbd>↑</kbd> | Move the focused window above in a column |
|
|
| <kbd>Mod</kbd><kbd>U</kbd> | Switch to the workspace below |
|
|
| <kbd>Mod</kbd><kbd>I</kbd> | Switch to the workspace above |
|
|
| <kbd>Mod</kbd><kbd>Ctrl</kbd><kbd>U</kbd> | Move the focused window to the workspace below |
|
|
| <kbd>Mod</kbd><kbd>Ctrl</kbd><kbd>I</kbd> | Move the focused window to the workspace above |
|
|
| <kbd>Mod</kbd><kbd>,</kbd> | Consume the window to the right into the focused column |
|
|
| <kbd>Mod</kbd><kbd>.</kbd> | Expel the focused window into its own column |
|
|
| <kbd>Mod</kbd><kbd>R</kbd> | Toggle between preset column widths |
|
|
| <kbd>Mod</kbd><kbd>F</kbd> | Maximize column |
|
|
| <kbd>Mod</kbd><kbd>Shift</kbd><kbd>E</kbd> | Exit niri |
