# 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. | |
