Objective

I use a hyprland plugin called hyprscroller to emulate the scroll functionality of PaperWM.
However, I can’t get whether I am in row mode or column mode, so I want to show the mode status on my waybar.

Related issue: https://github.com/dawsers/hyprscroller/issues/57

Implementation

I wrote two shell script under ~/.config/waybar/

• scroller_mode_listener.sh, responsible for listening the IPC message of hyprscroller and store that information in a tmp file. This script can be executed in hyprland config file using exec-once

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

  #!/bin/bash MODE_FILE="/tmp/hyprland_scroller_mode" function handle { if [[ ${1:0:8} == "scroller" ]]; then if [[ ${1:10:9} == "mode, row" ]]; then echo "Row" > "$MODE_FILE" elif [[ ${1:10:12} == "mode, column" ]]; then echo "Column" > "$MODE_FILE" #else #echo "" > "$MODE_FILE" fi hyprctl dispatch submap reset && pkill -SIGRTMIN+8 waybar # update the widget on waybar fi } # Initialize the mode file echo "" > "$MODE_FILE" socat - "UNIX-CONNECT:$XDG_RUNTIME_DIR/hypr/$HYPRLAND_INSTANCE_SIGNATURE/.socket2.sock" | while read -r line; do handle "$line"; done

• scroller_mode_reader.sh, responsible for reading the tmp file and return the json value to waybar to change the shown icon.

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

  #!/bin/bash MODE_FILE="/tmp/hyprland_scroller_mode" current_mode=$(cat "$MODE_FILE") if [[ "$current_mode" == "Row" ]]; then icon="Row" percent=0 class="mode-row" elif [[ "$current_mode" == "Column" ]]; then icon="Column" percent=100 class="mode-column" else icon="Row" percent=0 class="" fi echo "{\"text\":\"$icon\", \"tooltip\":\"Scroller Mode: $current_mode\", \"class\":\"$class\",\"percentage\": $percent}"

Then add the custom module to waybar in config file (we use signal to update the module):

1
2
3
4
5
6
7
8
9

"custom/scroller-mode": {
    "exec": "~/.config/waybar/scroller_mode_reader.sh",
    "return-type": "json",
    "interval": "once",
    "signal": 8,
    "on-click": "hyprctl dispatch submap reset && pkill -SIGRTMIN+8 waybar",
    "format": "{icon}",
    "format-icons": ["", ""],
}

Also remember to add the module to the bar:

1

"modules-right": ["custom/scroller-mode", "cpu", "memory", "temperature","battery","clock","custom/power"],

Then everything is done

After a certain upgrade of hyprland, I can no longer copy&paste across Wayland & XWayland apps, which is very annoying.
The relatied issue: https://github.com/hyprwm/Hyprland/issues/6132
Maybe fixed in: https://github.com/hyprwm/Hyprland/pull/6086

According to 6132 issue, some provide a walk around. I tailored it to adapt it to my system.

Create a shell in ~ directory, named clipsync.sh

#!/usr/bin/env sh
# Two-way clipboard syncronization between Wayland and X11.
# Requires: wl-clipboard, xclip, clipnotify.
#
# Usage:
#   clipsync.sh watch - run in background.
#   clipsync.sh kill - kill all background processes.
#   echo -n any | clipsync.sh insert - insert clipboard content fron stdin.
#
# Workaround for issue:
# "Clipboard synchronization between wayland and xwayland clients broken"
# https://github.com/hyprwm/Hyprland/issues/6132

# Updates clipboard content of both Wayland and X11 if current clipboard content differs.
# Usage: echo -e "1\n2" | clipsync insert
insert() {
  # Read all the piped input into variable.
  value=$(cat)
  wValue="$(wl-paste)"
  xValue="$(xclip -o -selection clipboard)"

  notify() {
    notify-send -u low -c clipboard "$1" "$value"
  }

  if [ "$value" != "$wValue" ]; then
    notify "Wayland"
    echo -n "$value" | wl-copy
  fi

  if [ "$value" != "$xValue" ]; then
    notify "X11"
    echo -n "$value" | xclip -selection clipboard
  fi
}

watch() {
  # Wayland -> X11
  wl-paste --type text --watch "/home/cyl/clipsync.sh" insert &

  # X11 -> Wayland
  while clipnotify; do
    xclip -o -selection clipboard | ~/clipsync.sh insert
  done &
}

kill() {
  pkill wl-paste
  pkill clipnotify
  pkill xclip
  pkill clipsync
}

"$@"

alias in ~/.zshrc:

1

alias clipsync="~/clipsync.sh"

enable it by running

1

clipsync watch

kill all by running

1

clipsync kill

Self-start, configured in ~/.config/hyprland/hyprland.conf

1

exec-once = clipsync watch

REMEMBER TO REMOVE ALL THESE STUFF WHEN HYPRLAND HAS FIXED THE ISSUE
