Acme::Anguish - Use Anguish programming language in your Raku programs
use Acme::Anguish;
anguish "\x2061" x 72 ~ "\x2063"; # prints "H"
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.
Takes a single positional argument: string of Anguish code to evaluate.
See examples
directory of this distribution for example Anguish programs.
The U-FEFF
character also serves as a file BOM, so avoid using it as the first character in your file.
