waycorner

Hot corners for Wayland. Create anchors in the corners of your monitors and execute a command of your choice.

Note: Currently only tested on swaywm. Though it should work on any Wayland compositor that supports the xdg-output protocol.

Cargo (crates.io)

cargo install waycorner --locked

Manually

cd waycorner
cargo install --path . --locked

Configuration

Default configuration location is ~/.config/waycorner/config.toml, this needs to be created manually. You can also specify a different location using --config. Preview your configuration with the --preview flag.

[left]
# Shell commands to execute when hotcorner is triggered,
# at least one is required.

# Command to run when cursor enters hotcorner.
# `command` is an alias for `enter_command`.
enter_command = [ "notify-send", "enter" ]
# Command to run when cursor exits hotcorner.
exit_command = [ "notify-send", "exit" ]

# Locations of the hot corners.
# Options:
# - for corners: top_left, top_right, bottom_right, and bottom_left;
# - for edges: top, bottom, right, left.
locations = ["bottom_right", "bottom_left"]  # default

# Size of the hot corners in pixels, for edges the size means the width
# for vertical edges, and height for horizontal edges. The other dimension
# will be the width/height of your display - the set margin.
size = 10  # default

# Margin on the sides of the hot edges, only applicable to edge locations.
# See the comment with sizes attribute above.
margin = 20  # default

# Timeout in milliseconds before command is triggered.
timeout_ms = 250  # default

# Hex color of the corner when previewed, supports transparency. (#AARRGGBB or #RRGGBB)
# (Useful for debuging purposes when setting up several hot corners.)
color = #FFFF0000  # default

# Optional output config to specify what output to use.
[left.output]
# Regex to match output descriptions on.
# Regex engine is similar to RE2: https://github.com/rust-lang/regex
#
# Use `swaymsg -t get_outputs` to get a list of outputs in the format:
# Output ${NAME} '${DESCRIPTION}'
description = ""  # default, empty means all outputs

Then add exec waycorner to your swaywm config.
