I’m working on hyprland, one thing I am missing from my awesomewm setup is rofi list all running windows. Sometimes I put a browser instance in a different workspace and I cant find it, especially if I’ve full screened something over top of it.

first pass
──────────

look for brave and go to it or make one

[code]
  #!/usr/bin/env bash
  
  addr=$(hyprctl clients -j | jq -r \
  	'.[] | select(.class == "brave-browser") | .address' | head -n1)
  
  if [ -n "$addr" ]; then
  	# Focus the existing browser window
  	hyprctl dispatch focuswindow address:$addr
  else
  	# Launch a new browser window
  	brave --password-store=basic &
  fi

second pass
───────────

If there are more than one cycle between them.

[code]
  # Get current window address
  current_addr=$(hyprctl activewindow -j | jq -r '.address')

  # Get all Brave window addresses
  brave_windows=($(hyprctl clients -j | jq -r '.[] | select(.class == "brave-browser") | .address'))

  num_windows=${#brave_windows[@]}

  if ((num_windows == 0)); then
  	# No Brave windows, launch it
  	brave --password-store=basic &
  	exit
  fi

  # Find the index of the current window in brave_windows
  current_index=-1
  for i in "${!brave_windows[@]}"; do
  	if [[ "${brave_windows[$i]}" == "$current_addr" ]]; then
  		current_index=$i
  		break
  	fi
  done

  # If we're already in a Brave window, switch to the next one (wrap around)
  if ((current_index != -1)); then
  	next_index=$(((current_index + 1) % num_windows))
  	hyprctl dispatch focuswindow address:${brave_windows[$next_index]}
  else
  	# Not currently in a Brave window — focus the first one
  	hyprctl dispatch focuswindow address:${brave_windows[0]}
  fi

third pass
──────────

Generalize it so that I can make keybindings for any app that I can figure out the classname of and provide a start command.

[code]
  #!/usr/bin/env bash
  
  set -euo pipefail
  
  # Args
  class="${1:-}"
  shift
  start_command="$*"
  
  if [[ -z "$class" || -z "$start_command" ]]; then
  	echo "Usage: $0 <class> <start-command...>"
  	exit 1
  fi
  
  # Current active window
  current_addr=$(hyprctl activewindow -j | jq -r '.address')
  
  # All windows with matching class
  matching_windows=($(hyprctl clients -j | jq -r --arg class "$class" '.[] | select(.class == $class) | .address'))
  
  num_windows=${#matching_windows[@]}
  
  if ((num_windows == 0)); then
  	# None running — start it
  	eval "$start_command" &
  	exit
  fi
  
  # See if currently focused window is in matching list
  current_index=-1
  for i in "${!matching_windows[@]}"; do
  	if [[ "${matching_windows[$i]}" == "$current_addr" ]]; then
  		current_index=$i
  		break
  	fi
  done
  
  # Cycle to next window if already in one
  if ((current_index != -1)); then
  	next_index=$(((current_index + 1) % num_windows))
  	hyprctl dispatch focuswindow address:${matching_windows[$next_index]}
  else
  	# Not in one — focus first
  	hyprctl dispatch focuswindow address:${matching_windows[0]}
  fi

finding the classname
─────────────────────

[code]
  ❯ hyprctl clients -j | jq | grep kitty

      "class": "kitty",
      "initialClass": "kitty",
      "initialTitle": "kitty",
