{{implementation|Brainf***}}
A Brainf*** compiler written by [[User:IanOsgood|Ian Osgood]] in [[Forth]].
==Usage==
Load the code your preferred Forth environment. The code will define the
===Compiling Brainf*** code===
Let's say you have this sequence that prints a capital A:
++++++[>+++++++++++<-]>-.
You can compile it by using the ''':bf''' word:
:bf
Your Brainf*** code is now compiled in your Forth environment as the word '''printA'''. If you want to use a different
Larger BF programs may be loaded from a file instead of parsed from the interpreter:
:bf-file bottles bottles.bf
===Running the compiled Brainf*** code===
Assuming you used the word '''printA''' from the above example, you can execute your code by running the word:
