Schemoji

An emoji-based language structured on Scheme's syntax.

examples

Check out the tests folder for Scheme (.scm) and Schemoji (.smoji) equivelent files.

Simple factorial code:

(begin
    (define fact (lambda (n) (if (<= n 1) 1 (* n (fact (- n 1))))))
    (print (fact 10))
)

🔸👌
    🔸✏️ fact 🔸🐏 🔸n🔹 🔸☯️ 🔸🌜 n 1🔹 1 🔸🇽 n 🔸fact 🔸➖ n 1🔹🔹🔹🔹🔹🔹
    🔸🙈 🔸fact 10🔹🔹
🔹

conversion

run convertall.py or src/converter.py to convert between Scheme and Schemoji There's a --prettify flag that, when set, changes the open-close parens to be dialer keycode emojis, representing scope-depth.

to run

e.x. python -m src.run tests/circle_area.smoji

For Scheme, these files are tested against Chicken Scheme.

language rules

The rules are defined in src/mapping.py

python env

using conda: conda create --name schemoji --file env.txt
