river

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

Note: river is currently early in development. Expect breaking changes and missing features. If you run into a bug don't hesitate to open an issue

Design goals

• Simplicity and minimalism, river should not overstep the bounds of a window manager.
• 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:

• zig 0.7.1
• wayland
• wayland-protocols
• wlroots 0.12.0
• xkbcommon
• libevdev
• pixman
• pkg-config
• scdoc (optional, but required for man page generation)

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

Then run, for example:

zig build -Drelease-safe=true --prefix /usr install

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

Usage

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

On startup river will look for and run an executable file at one of the following locations, checked in the order listed:

• $XDG_CONFIG_HOME/river/init
• $HOME/.config/river/init
• /etc/river/init

Usually this executable init file will be a shell script invoking riverctl to create mappings and preform other configuration. The init file path may be overridden with the -c flag.

An example init script with sane defaults is provided here in the example directory and installed to /etc/river/init.

For a complete list of commands and documentation see the riverctl(1) man page.
