river

river is a dynamic wayland compositor that takes inspiration from dwm and bspwm.

Note: river is currently early in development and may lack some features. If there are specific features blocking you from using river, don't hesitate to open an issue

Design goals

• Simplicity and minimalism, river should not overstep the bounds of a window manger.
• Dynamic window management based on a stack of views and tags like dwm.
• Scriptable configuration and control through a separate binary, riverctl, like bspwm. This works using the custom river-control protocol.

Building

To compile river first ensure that you have the following dependencies installed:

• zig 0.6.0
• wayland
• wayland-protocols
• wlroots 0.10.1
• xkbcommon
• pixman
• pkg-config

Note: NixOS users should refer to the Building on NixOS wiki page

Then run, for example, sudo zig build --prefix /usr/local install to build and install the river and riverctl binaries to /usr/local/bin. To enable experimental Xwayland support pass the -Dxwayland=true option.

Usage

River can either be run nested in an X11/wayland session or directly from a tty using KMS/DRM.

River has no keybindings by default; mappings can be created using the map command of riverctl. Generally, creating mappings and other configuration is done with a shell script. River will execute any arbitrary shell command passed with the -c flag during startup. For example:

river -c /path/to/config.sh

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

Some configuration options are still hardcoded in Config.zig. Eventually all configuration will be moved to the riverctl binary.
