#
#   Use wofi to pick emoji because that's what this
#   century is about apparently...
#   
#   Requirements:
#     wofi, wlroots based compositor 
#
#   Usage:
#     1. Download all emoji
#        $ wofi-emoji --download
#
#     2. Run it!
#        $ wofi-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.

Thank you very much, finally something that seems to work reliably for me under sway! :)
I've been trying different solutions, like rofimoji, splatmoji and so on, but couldn't get any of them to keep properly functioning without having to constantly mess around with manually synchronizing the xwayland clipboard and such hacks, so I have almost decided to write my own, but then I found your nice solution, which saved me a great amount of time!

Pasting the emoji directly in this doesn't work properly. I hacked together a solution using wtype, you can find it in my fork. I don't know how to suggest a revision here :)

Wow, I've been using it for a while and have just now realized that it wasn't properly respecting my wofi config (I set layer=overlay because of this: https://www.reddit.com/r/swaywm/comments/hyti1v/wofi_appears_under_full_screen_windows/), so I started tinkering and through some trial and error realized that it was because of the single hyphen parameters. -dmenu should be --dmenu and so one. After I fixed that it started properly appearing on top of fullscreen windows and I saw the proper sizing that you have originally intended for it. 😃

Edit: After digging a bit more into it I think that it was disrespecting the layer config because of the -dmenu flag being interpreted as the combination of -d, -m and so on, among which -n meant --normal-window.
