#Rivercarro

A slightly modified version of rivertile layout generator for river

Compared to rivertile, rivercarro add:

• monocle layout
• smart gaps
• "true" inner gaps instead of padding around views

I don't want to add too much complexity, the only thing I intend to add now is smart borders, after that I'll consider rivercarro features complete. If you want a layout generator with more features and configuration, have a look at some others great community contributions like stacktile or kile.

#Building

Same requirements as river, use zig 0.8.1, if river and rivertile works on your machine you shouldn't have any problems.

Init submodules:

git submodule update --init

Build, e.g.

zig build --prefix ~/.local

Note that rivercarro use pkgconfig for the river-layout-v3 protocol so if you did not installed river system wide you need to set PKG_CONFIG_PATH in your shell rc.

e.g.

export PKG_CONFIG_PATH="$HOME/.local/share/pkgconfig"

#Usage

Works exactly as rivertile, you can just replace rivertile name by rivercarro in your config, and read rivertile(1) man page

e.g. In your river init (usually $XDG_CONFIG_HOME/river/init)

# Mod+H and Mod+L to decrease/increase the main ratio of rivercarro
riverctl map normal $mod H send-layout-cmd rivercarro "main-ratio -0.05"
riverctl map normal $mod L send-layout-cmd rivercarro "main-ratio +0.05"

# Mod+Shift+H and Mod+Shift+L to increment/decrement the main count of rivercarro
riverctl map normal $mod+Shift H send-layout-cmd rivercarro "main-count +1"
riverctl map normal $mod+Shift L send-layout-cmd rivercarro "main-count -1"

# Mod+{Up,Right,Down,Left} to change layout orientation
riverctl map normal $mod Up    send-layout-cmd rivercarro "main-location top"
riverctl map normal $mod Right send-layout-cmd rivercarro "main-location right"
riverctl map normal $mod Down  send-layout-cmd rivercarro "main-location bottom"
riverctl map normal $mod Left  send-layout-cmd rivercarro "main-location left"
# And for monocle
riverctl map normal $mod M     send-layout-cmd rivercarro "main-location monocle"

# Set and exec into the default layout generator, rivercarro.
# River will send the process group of the init executable SIGTERM on exit.
riverctl default-layout rivercarro
exec rivercarro

#Command line options

Run zig fmt and wrap line at 100 columns unless it helps the readability.
