river

River is a dynamic tiling Wayland compositor with flexible runtime configuration.

Join us at #river on irc.libera.chat. Read our man pages and our wiki.

Note: river is currently early in development. Expect breaking changes and missing features. Bugs should however be rare at this point, if you run into one don't hesitate to open an issue

Design goals

• Simple and predictable behavior, river should be easy to use and have a low cognitive load.
• Window management based on a stack of views and tags.
• Dynamic layouts generated by external, user-written executables. A default rivertile layout generator is provided.
• Scriptable configuration and control through a custom Wayland protocol and separate riverctl binary implementing it.

Building

On cloning the repository, you must init and update the submodules as well with e.g.

git submodule update --init

To compile river first ensure that you have the following dependencies installed. The "development" versions are required if applicable to your distribution.

• zig 0.9
• wayland
• wayland-protocols
• wlroots 0.15
• xkbcommon
• libevdev
• pixman
• pkg-config
• scdoc (optional, but required for man page generation)

Then run, for example:

zig build -Drelease-safe --prefix ~/.local install

To enable experimental Xwayland support pass the -Dxwayland option as well.

Usage

River can either be run nested in an X11/Wayland session or directly from a tty using KMS/DRM. Simply run the river command.

On startup river will run an executable file at $XDG_CONFIG_HOME/river/init if such an executable exists. If $XDG_CONFIG_HOME is not set, ~/.config/river/init will be used instead.

Usually this executable is a shell script invoking riverctl(1) to create mappings, start programs such as a layout generator or status bar, and perform other configuration.

An example init script with sane defaults is provided here in the example directory.

For complete documentation see the river(1), riverctl(1), and rivertile(1) man pages.
