BFInfinity

This is still a work in progress. It may be changed in the future.

BFInfinity is a completely open-source brainfuck derivative. 'Open-source', in this context, means that you can add anything to it. You want a 6th dimension (There is already a 15th (technically infinite) dimension though)? You got it! Just add a section in the 'Specifications' section for how exactly it works.

Rules

1. Any UTF-8 character can be used EXCEPT letters from the latin alphabet and numbers, no matter how many accents they have.

2. Add your username with the instruction(s). You should let others know who are you.

3. Don't delete anyone else's work! I think this is pretty straight-forward.

4. Explain things clearly and precisely. Don't go into infinite details either.

5. Fixing mistakes other people make is fair game!

6. Have fun with it! You can add anything.

7. When adding a command, please make sure that the character you use are not used by other commands.

Specifications

Base Specs

BFInfinity has an infinite number of initially 8-bit unsigned cells positioned on a 15D grid. It also has a stack and a deque and a queue. It also has a dictionary with string keys and 8-bit integer values. It also has a weighted 8-bit full binary tree. It also has a directed graph. It also has a sorted set. It also has infinite locks, numbered from 0 to infinity. It also has time travel and timelines. It also has a continuation stack (continuations keep everything except the continuation stack & IP). It also has a dimension counter, range is 1~infinity.

Let X be current instruction number.

Repeated Commands

If 2 commands share a symbol, then: (unknown values are treated as 0)

• If current cell value mod 2 is 1, then take the first command in the order of the table.
• Else, take the second command.

The same applies if 3 or more commands share a symbol.

Commands

All non-commands are comments.

BFInfinity currently has the following commands (it's always under construction):
