# 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.
UNICODE_FILE="$HOME/.dotfiles/rofi/scripts/unicode.txt"
# Urls of emoji to download.
# You can remove what you don't need.
