Delvs

Delvs(pronounced /delve-iss/) is a Brainfuck extension similar to Brainfuck++ designed in February 2013 by User:L8D. The primary purpose was to combine many other Brainfuck derivitaves like Brainfuck++ and Boolfuck, and the language(and Interpreter) are still in development.

Instructions

Delvs currently has 10 additional instructions.

Command	Description	Pseudo Code
:	Cast current cell's value to string and print	printf("%hhd", *p);
;	Read number set from stdin and store in current cell	scanf("%hhd", p);
#	Read following cells as null-terminating string for filename, then if current cell is not 1, open file for reading, or if 1, open file writing	f = fopen(p + 1, p == 1 ? "w" : "r");
`	Read next char from file stream and store in current cell	*p = fgetc(f);
!	Write current cell's value to file stream	fputc(*p, f);
"	Move bit to the right once	b <= 0 ? b = 7 : b--;
'	Toggle/flip bit and move bit to the right once	*p ^= (1 << b); b <= 0 ? b = 7 : b--;
\	Comments out rest of line	while(*c++ != '\n');
@	Prints out surround cell values in a formatted way. Basically a breakpoint for debugging	printf("%hhd : %hhd : %hhd : %hhd : %hhd", *(p - 2), *(p - 1), *p, *(p + 1), *(p + 2));
$	Sleeps the current cell's value in seconds	sleep(*p);

To do

• implement a working socket system
• implement an stdout flushing system
• implement runtime args
• implement namespaces (separate arrays of 30000 chars)
• (maybe) implement better way to divide
• implement full integers
