Unicat

Unicat is an esoteric programming language created in 2015 by User:Gemdude46.

The language is programmed using the 9 cat emoji: ( 😸 😹 😺 😻 😼 😽 😾 😿 🙀 ) All other characters are ignored.

Memory is an infinite tape of signed bignums.

A Unicat interpreter, as well as examples, can be found on Github.

Hello, world! is as follows:

A full documentation is yet to be written.

Any string is a valid Unicat program, although most will loop forever.
