Roadrunner Interpreter v1.0

# Brainf*ck Clone Interpreter v1.0
# Created by Connor Scialdone
#
# Language Implemented:
#   Name: Roadrunner
#   Version: 1.0
#   Author: Connor Scialdone
#
#   More Info:
#       Roadrunner was a stupid idea that ended up turning into
#       a full-on Brainf*ck clone interpreter in which I
#       implemented the language. So yeah!
#
#       It's based off the popular Looney Tunes character by the
#       same name; all the commands are just "meep" with different
#       capitalization.
#
#   More documentation is maintained here: https://esolangs.org/wiki/Roadrunner

# Syntax list
# Each entry is stored by the Brainf*ck equivalent and contains
#   the translated token.
# 'sep' is the token separator; note that it can be empty (if it is, tokens are assumed to be single characters).
syntax = {
    '>': 'meeP',
    '<': 'Meep',
    '+': 'mEEp',
    '-': 'MeeP',
    '.': 'MEEP',
    ',': 'meep',
    '[': 'mEEP',
    ']': 'MEEp',
    'sep': ' ',
}
