Brainfuck 0.1

This is a little project that I wrote in QB64.
It contains three CLI tools:

  • the Brainfuck Compiler "BFC.exe"
  • the Brainfuck Assembler "BFASM.exe"
  • the Brainfuck Interbreter "BF.exe"

The Brainfuck Compiler

"BFC.exe" compiles your Brainfuck source code into byte code. The calling syntax is as follows: bfc <sourceFile>

Important: Do not provide a file extension, because the compiler assumes source files having ".bf" and byte code file having ".bfc".

Brainfuck knows 8 commands:

  • ">" = goto next cell
  • "<" = goto previous cell
  • "+" = increment current cell
  • "-" = decrement current cell
  • "[" = begin a loop if current cell is not 0
  • "]" = repeat loop if current cell is not 0
  • "." = print out an ASCII character
  • "," = read in an ASCII character

You can also provide a number, to multiply the number of executions. Following numbers will be added together.

Examples:

  • "+7" = increment seven times
  • "+0" = do not increment at all
  • "-55" = decrement ten (5+5) times

The Brainfuck Assembler

"BFASM.exe" compiles your Brainfuck Assembler code into byte code. The calling syntax is as follows: bfasm <sourceFile>

Important: Do not provide a file extension, because the assembler assumes source files having ".bfa" and byte code file having ".bfc".

The Brainfuck Assembler knows the following commands:

  • "st_X": byte code "X", where X is a hexadecimal digit (0-9,A-F)
  • "add" / "inc": increment current cell
  • "cin" / "in" / "inp": read in an ASCII character
  • "cout" / "out": print out an ASCII character
  • "dec" / "sub": decrement current cell
  • "if" / "while": begin a loop, if current cell is not 0
  • "loop" / "loopne" / "loopnz": repeat loop, if current cell is not 0
  • "nop": perform no operation
  • "pop": goto previous cell
  • "push": goto next cell
  • "ret": return from subroutine

The Brainfuck Interpreter

"BF.exe" runs your compiled Brainfuck byte code. The calling syntax is as follows: bf <sourceFile>

Important: Do not provide a file extension, because the interpreter assumes files having ".bc"

The code is running inside a BVM, i.e. a Brainfuck Virtual Machine, refering to JVM (Java Virtual MAchine).
