+# SWAYFOCUS - Window Switching Tool For Sway
+
+A tool to focus a specific window in sway, useful for run or raise scripts that would have used xdotool or wmctrl under Xorg.
+Uses swaymsg to communicate. Windows hidden to the system tray don't show up in the get_tree command, so they can't be raised with this.
+
+## Usage
+```
+Usage: swayfocus [OPTIONS]
+    -v, --version                    Show Version
+    -h, --help                       Show Help
+    -p, --print                      Print window names and exit
+    -c, --cycle                      Cycle through all matching windows in order, instead of selecting the first in the list    
+	-n WNAME, --name=WNAME           Match against window name
+    -m WMARK, --mark=WMARK           Match against window mark
+    -t WTYPE, --type=WTYPE           Match against window type (app_id for wayland, class for xwayland)
+```
+Select at least one matching option.
+
+## Examples
+```
+swayfocus -p | sort -u | bemenu | xargs swayfocus -c --name=
+# simple window switcher
+```
+
+## Installation
+```
+make && sudo make install
+```
