Your Custom Brainfuck

See examples.

You can execute original programming language like brainfuck with JSON config file.

This is a config JSON for a standard brainfuck.

{
  "next": ">",
  "prev": "<",
  "inc": "+",
  "dec": "-",
  "read": ",",
  "write": ".",
  "open": "[",
  "close": "]",
  "whitespaces": " \t\r\n"
}

When you want PPAP programming language, you can get it with a following JSON:

{
  "next": "apple",
  "prev": "pinapple",
  "inc": "I",
  "dec": "have",
  "read": "pen",
  "write": "Uh",
  "open": "[",
  "close": "]",
  "whitespaces": " \t\r\n"
}

You can execute your PPAP program:

# PPAP program source code
$ cat helloworld.ppap
IIIIIIIII[appleIIIIIIIIappleIIIIIIIIIIIappleIIIIIpinapplepinapplepinapplehave]appleUhappleIIUhIIIIIIIUhUhIIIUhapplehaveUhhavehavehavehavehavehavehavehavehavehavehavehaveUhpinappleIIIIIIIIUhhavehavehavehavehavehavehavehaveUhIIIUhhavehavehavehavehavehaveUhhavehavehavehavehavehavehavehaveUhappleIUh

# Execute your PPAP program
$ brainfuck-go -conf ppap.json helloworld.ppap
Input: IIIIIIIII[appleIIIIIIIIappleIIIIIIIIIIIappleIIIIIpinapplepinapplepinapplehave]appleUhappleIIUhIIIIIIIUhUhIIIUhapplehaveUhhavehavehavehavehavehavehavehavehavehavehavehaveUhpinappleIIIIIIIIUhhavehavehavehavehavehavehavehaveUhIIIUhhavehavehavehavehavehaveUhhavehavehavehavehavehavehavehaveUhappleIUh
