Rofi emoji picker

rofi-emoji.sh

#!/usr/bin/env bash
#
#   Use rofi to pick emoji because that's what this
#   century is about apparently...
#
#   Requirements:
#     rofi, xsel, xdotool, curl, xmllint
#
#   Usage:
#     1. Download all emoji
#        $ rofi-emoji --download
#
#     2. Run it!
#        $ rofi-emoji
#
#   Notes:
#     * You'll need a emoji font like "Noto Emoji" or "EmojiOne".
#     * Confirming an item will automatically paste it WITHOUT
#       writing it to your clipboard.
#     * Ctrl+C will copy it to your clipboard WITHOUT pasting it.
#

# Where to save the emojis file.
EMOJI_FILE="$HOME/.cache/emojis.txt"

# Urls of emoji to download.
# You can remove what you don't need.

it works @tadly 👌✅🚀 gangelop/dotfiles@9225039

Just encountered this same problem & delighted to see it also fixed here :) This XPath might be more robust to future markup changes: //ul[contains(@class,"emoji-list")]

This project is a crime and I love it.

Wrote this patch to download the list from the official unicode website instead of emojipedia. This only requires one download, should have a more stable format over time and cuts out the xmllint dependency + most of the parsing code.

Here is a fork of @omc8db's fork that works with wayland, fixes an error with recent versions of rofi that prevents it from launching because ctrl+c is already bound by rofi, and fixes shellcheck warnings. https://gist.github.com/mmirus/840c907f02dfb491a150be4e459893d1
