Backwards compatible Brainfuck language-extension

Brainlove

Backwards compatible Brainfuck extension. Currently supports Macros (Functions) using horribly annoying syntax, as to keep with the spirit of brainfuck. The interpreter handles both Brainfuck and Brainlove files.

💬 This project is not optimized, condensed or follows any proper styleguide - it doesn't matter, it's a one-off project meant as a joke.

Syntax

As with normal Brainfuck files, the operations: < > + - , . [ ] are all supported.

to utilize the macro-feature of Brainlove, the following syntax must be used:

• ł - marks the start of a macro, this should be followed by any [a-Z]+[a-zA-Z0-9]* identifier.

• % - marks the end of said identifier

• # - marks the end of the code the macro contains

• ŋmyfunctionNameð here shows that to call a macro, one must prefix and suffix the function identifier with ŋ and ð respectively

Nested macros are supported, meaning that this definition would be a valid macro:

łsub10%----------#

łsub30%
ŋsub10ð
ŋsub10ð
ŋsub10ð
#

Usage

python3 interpreter.py [sourcefile]

Examples

The examples/ directory contains a few examples of both brainlove and brainfuck applications, examples of the extended languages features are showcased in the former.
