brainfuck-fuck
Just a nice little brainfuck interpreter in Python.
Nope! This is brainfuck-fuck. You know there's C, then C+, then C++? Well, there's brainfuck, and now there's brainfuck-fuck. Brainfuck-fuck is supposedly backwards compatible. So therefore this:
+++++++ [ > ++++++++++ < - ] > ++ . [-]<[-] ++++++++++ [ > ++++++++++ < - ] > +++++ .
does exactly the same thing as this:
=H.=i.
besides the fact that the first one uses two cells while the second uses one.
A full list of additions:
- The
=
command. This sets the current cell's value to the ASCII value of the character after the=
. Therefore=H
sets the cell to 72 (the ASCII value of H). - An if/else statement!
The syntax is
? (code) : (code) !
. When a?
is reached, it checks the current cell. If the current cell is 0, it skips to the corresponding:
. Otherwise, it continues on until the:
, then skips to the!
. Thus+ ? =Y : =N ! .
prints out "Y" while? =Y : =N ! .
prints out "N". - Functions! To define a function, use
(@ symbol)(single ASCII character)(code)(pipe, |)
, e.g.@F+++++|
(which simply adds 5). To call a function, use a caret (^
) and then the ASCII character used to name the function, e.g.^F
(which calls the previously defined functionF
, thereby adding 5).
