PROGRAM:
NAME
bf - yet another Brainfuck interpreter
SYNTAX
bf [-h] [options] <filename>
DESCRIPTION
bf ('Yet another Brainfuck interpreter') is a simple interpreter for the esoteric
Brainfuck language.
OPTIONS
-c<num>
Specify the number num of the last cell you are allowed to use in your Brainfuck
program.
So if you use -c0 (or just -c), you'll have one cell (one byte in memory) to use on
your tape. Brainfuck interpreter by Urban Mueller used an array of 30000 bytes
(-c29999).
Our default value is 9999. Usually you need less.
-i Output Brainfuck code input to stderr.
This feature is useful if you can't find out why some Brainfuck code doesn't work
the way it should e.g. ignored loops, or a Brainfuck character within a comment.
Note: Up to 32 +, -, < and > are summarized and displayed as only one. This feature
was introduced in version 20040423.
-n Some Brainfuck contests specify a 0 byte as End Of Input. So -n translates a \n
byte input into a 0 byte input. Disadvantage: the input can only consist of one
line.
-w Disallow byte wrap-around. This causes errors if you try to decrement ('-') a 0x00
byte or to increment ('+') a 0xFF byte.
This feature is useful if you want to take part in Brainfuck contests where such
wrapping-around is disallowed.
By default (without -w), incrementing 0xFF results in 0x00 and decrementing 0x00
results in 0xFF.
-,<mode>
Specify input mode. <mode> can be:
0 (zero) Normal input using getchar(3).
1 Single-char input. You won't see what you type.
2 Single-char input. You will see what you type.
3 The same as 1, but doesn't allow escape characters if compiled with slang.
4 The same as 2, but doesn't allow escape characters, if compiled with slang.
(recommended)
Default is 0. (In some versions the default was 4.)
LIMITATIONS
It's not allowed to '<' below the first cell.
It's not allowed to '>' beyond the last cell.
