Quick pop-up emoji input on Linux

I need pop-up Linux emoji input that doesn’t require a mouse. Something like Emoji Keyboard or EmojiOne Picker require the hands to leave the keyboard and click on an emoji – this is a bunch  better than jumping into a web browser and looking one up, but still. Yuck.

The solution I finally found is ibus-uniemoji. Ibus is a framework on Unix that is most generally used for input of foreign characters from a standard keyboard, e.g. pinyin, Russian, or in this case, emoji. Uniemoji uses this to provide an easy pop-up for emoji selection by name or keyword. No mouse!

Ensure the ibus daemon is running at startup, or whenever suits you:

It’s not in the Ubuntu repos as of writing, so to install:

Here is the script I wrote to toggle between normal input and emoji input:

And finally to toggle between (or cycle across) an arbitrary number of ibus engines, find the engines you want by running ibus list-engine and call the script like this from some key combination (see your X or window manager config, whatever):

In my case, I bound this via my i3 config:

Note: you may, like me, need to re-establish your X keyboard settings after each time you switch ibus engines or else you’ll lose your compose keys, maps, etc. To ensure this I just re-run my .xsession as above.
