Brainfuck Interpreter

INFORMATION
It is a plugin to interpret codes esoteric programming language BrainFuck in PAWN in a simple way.

Quote:

The language is based on a simple execution model consisting, besides the program, a vector of (at least) 30,000 bytes initialized to zero, a pointer to the vector (at the beginning of execution points to the first element of the vector) and two "streams" of bytes for input and output.

NATIVES

pawn Код:

native _BFInterpret(dest[], code[], len = sizeof(dest));

To use it simply define the native and add the plugin to server.cfg.

EXAMPLES ..

pawn Код:

native _BFInterpret(dest[], code[], len = sizeof(dest));

main()
{
    new
        str[150]
        ;
        
    _BFInterpret(str, "++++[++++>---<]>++.[--->+++++<]>.+.+++[->+++<]>.--[--->+<]>-.+[->+++<]>++.[--->+<]>----.+[---->+<]>+++.---[->++++<]>+.-------.-[->+++++<]>-.+[->+++<]>++.+++++.-----.++++++++.+++.----.+++.[--->+<]>-----.+[->+++<]>+.+.--[--->+<]>-.+[->++<]>.---[----->+<]>-.+++[->+++<]>++.++++++++.+++++.-[->+++<]>-.[++>-------<]>.+[->+++<]>+.++++++++.+[++>---<]>-.");
    printf("\n\n\n\n%s\n\n", str);
}

Quote:

The code "Hello World!" would be written in a single line: pawn Код: _BFInterpret(str, "-[------->+<]>-.-[->+++++<]>++.+++++++..+++.[--->+<]>-----.---[->+++<]>.-[--->+<]>---.+++.------.--------.-[--->+<]>.");

Output: Hello World!

pawn Код:

/* This program prints "Hello World!" and a newline to the screen, its
  length is 106 active command characters [it is not the shortest.]

  This loop is a "comment loop", it's a simple way of adding a comment
  to a BF program such that you don't have to worry about any command
  characters. Any ".", ",", "+", "-", "<" and ">" characters are simply
  ignored, the "[" and "]" characters just have to be balanced.

]                       //Loop till Cell #0 is zero; number of iterations is 8

/*The result of this is:
Cell No :   0   1   2   3   4   5   6
Contents:   0   0  72 104  88  32   8
Pointer :   ^

>>.                     Cell #2 has value 72 which is 'H'
>---.                   Subtract 3 from Cell #3 to get 101 which is 'e'
+++++++..+++.           Likewise for 'llo' from Cell #3
>>.                     Cell #5 is 32 for the space
<-.                     Subtract 1 from Cell #4 for 87 to give a 'W'
<.                      Cell #3 was set to 'o' from the end of 'Hello'
+++.------.--------.    Cell #3 for 'rl' and 'd'
>>+.                    Add 1 to Cell #5 gives us an exclamation point
>++.                    And finally a newline from Cell #6*/

Possibly they knew that it is based on the ASCII table.

instructions:

Character	Meaning
>	increment the data pointer (to point to the next cell to the right).
<	decrement the data pointer (to point to the next cell to the left).
+	increment (increase by one) the byte at the data pointer.
-	decrement (decrease by one) the byte at the data pointer.
.	output the byte at the data pointer.
[	if the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command.
]	if the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command.

This is not absolute use (or maybe yes), can be used simply as a plugin to help you learn this language, possibly always is good to learn something new.
