🌈 Scheme, now written with emojis.

🌈 escm <your-code>.escm

Scheme, now written with emojis. Install it on your computer by downloading escm.py and editing your shell's configuration path to include:

escm() {
  if [ -z "$1" ]; then
    echo "Usage: escm [path_to_file].escm"
  else
    if [[ $1 == *.escm ]]; then
      python3 /path/to/escm.py "$1"
      [your_scheme_interpreter] "${1%.escm}.scm"
    else
      echo "Usage: escm [path_to_file].escm"
    fi
  fi
}

Here's an example snippet that prints the 21st number in the Fibonacci sequence:

(🟰 (fibonacci n) (🤷 (< n 2) n (+ (fibonacci (- n 1)) (fibonacci (- n 2)))))

(🖨️ (fibonacci 21))

Usage is fairly simple, write Scheme as you usually would but use emojis for actions / command words instead of words.

🐻 Shoutout to any future 61A-ers learning Scheme! That was the inspiration for this project... wahoo :)
