HeadFuck
A brainfuck-based esoteric programming language
Language specs:
Old operators (brainfuck)
> - increment pointer
< - decrement pointer
+ - increment cell value
- - decrement cell value
* - write byte from attached input into current cell
^ - write byte to attached output
[ - loop while current cell != 0 open
] - loop closing
New operators: [Done: 9.5/14]
. - reset pointer
_ - set cell value to 0
! - terminate program with exit code equal to current cell
@*or^a-z - attach stream to input/output, if self passed as argument, then default value is assigned
a-z - call a function (argument is current cell, return gets placed in the same cell)
Preallocation:
#a-z - put value/reference from preallocated memory into current cell (variables)
: - preallocated code section open
; - preallocated code section close
, - next declaration
{ - function scope open
} - function scope close
a-z{<code>} - declare a function
a-z"<string>"
a-z'<signed long long int>'
<comment> - comment
STD functions:
(f)
Call: creates a file with either a numeric name if argument is a byte value, or alphabetic name if argument is a string reference.
@ operator: opens handle to file with specified name and assigns it to chosen stream. If file does not exist, do nothing.
(m)
Call: shows an info message box with either number represented by current byte value or string.
Sample programs:
hello world:
>+++++++++[<++++++++>-]<^>+++++++[<++++>-]<+^+++++++^^+++^[-]>++++++++[<++++>-]<^>+++++++++++[<++++++++>-]<-^--------^+++^------^--------^[-]>++++++++[<++++>-]<+^[-]++++++++++^
Write "hello world" to a file:
f@^f>+++++++++[<++++++++>-]<^>+++++++[<++++>-]<+^+++++++^^+++^[-]>++++++++[<++++>-]<^>+++++++++++[<++++++++>-]<-^--------^+++^------^--------^[-]>++++++++[<++++>-]<+^[-]++++++++++^
