NAME

Acme::Anguish - Use Anguish programming language in your Raku programs

SYNOPSIS

use Acme::Anguish;

anguish "\x2061" x 72 ~ "\x2063"; # prints "H"

DESCRIPTION

Anguish is a Brainfuck variant that uses invisible Unicode characters instead of traditional Brainfuck's ones.

Here's the mapping of Brainfuck operators to Anguish:

> [⁠] U+2060 WORD JOINER [Cf]
< [​] U+200B ZERO WIDTH SPACE [Cf]
+ [⁡] U+2061 FUNCTION APPLICATION [Cf]
- [⁢] U+2062 INVISIBLE TIMES [Cf]
. [⁣] U+2063 INVISIBLE SEPARATOR [Cf]
, [] U+FEFF ZERO WIDTH NO-BREAK SPACE [Cf]
[ [‌] U+200C ZERO WIDTH NON-JOINER [Cf]
] [‍] U+200D ZERO WIDTH JOINER [Cf]

All other characters are silently ignored.

The meaning of original Brainfuck characters are as follows:

> 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.
, accept one byte of input, storing its value in 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.

SUBROUTINES

anguish

Takes a single positional argument: string of Anguish code to evaluate.

EXAMPLES

See examples directory of this distribution for example Anguish programs.

BUGS AND CAVEATS

The U-FEFF character also serves as a file BOM, so avoid using it as the first character in your file.
