+# waycorner
+
+Hot corners for Wayland. Waycorner allows you to create anchors on specified locations 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._
+
+## Installation
+
+Currently only available on AUR. Feel free to make an issue if you would like to see it elsewhere and have some time available to help.
+
+### Manually
+
+```zsh
+git clone [email protected]:AndreasBackx/waycorner.git
+cd waycorner
+cargo install --path .
+```
+
+## 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.
+
+```toml
+[left]
+# Shell command to execute when hotcorner is triggered.
+command = "lock"  # required
+
+# Locations of the hot corners.
+# Options: top_left, top_right, bottom_right, and bottom_left.
+locations = ["bottom_right", "bottom_left"]  # default
+
+# Size of the hot corners in pixels.
+size = 10  # default
+
+# Timeout in milliseconds before command is triggered.
+timeout_ms = 250  # 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.
+
+## Logging
+
+Pass `RUST_LOG` with either `trace`, `debug`, `info`, `warn`, or `error`. To set the logging level, default is `error`. See [env_logger documentation](https://docs.rs/env_logger/0.8.3/env_logger/).
