Delvs(Pronounced Del-vis) is my own personal variation of brainfuck, the interpreter is written in C. File reading was inspired by brainfuck++, and the bit fiddling was inspired by boolfuck(DuckDuckGo them if you have to, I'm not putting links there right now)
:casts the current value to a string and prints it.;grabs value from user input and casts to cell value.#reads following cells as null-terminating string for filename, then if current cell is != 1, open file for reading, or if 1, open file writing.`read next char from file, apply to current cell.!write char from current cell to file."increment current bit position by 1.'flip bit at current bit position, then incrment current bit position by 1.\ ...ignore EVERYTHING until newline is reached.$sleeps the current cell's value in seconds.%reads following cells as null-terminating string for address, and null-spaced port after that, then it opens a socket at that address.^sends current cell to socket.&reads on byte from socket and apply to current cell.*simply flushes stdout.
Corresponding lines of code:
:printf("%hhd", *p);;scanf("%hhd", p);#f = fopen(p + 1, p == 1 ? "w" : "r");`*p = fgetc(f);!fputc(*p, f);"b++;'*p ^= (1 << b)\ ...while(*c) if(*c++ == '\') return;$sleep(*p);%makesocket(p, (int)*++t);^send(s, p, 1, 0);&recv(s, p, 1, 0);*fflush(stdout);
- implement runtime args
- implement namespaces(seperate arrays of 30000 chars)
- (maybe) implement better way to divide
Setting entire cell values with just the bit intructions is as easy as converting 0's to "s and 1's to 's.
01001000 = 72
"'""'""" . >
01101001 = 105

Block comments are very straight forward to use, just plant a \[ when you start "commenting" and a ] when you're done.

How about reading files? Just generate a string as the filename an the use a # at the beginning of it. Like so:
01101101 m
"''"''"'
01111001 y
"''''""'
01110100 t
"'''"'""
01100101 e
"''""'"'
01111000 x
"''''"""
01110100 t
"'''"'""
01100110 f
"''""''"
01101001 i
"''"'""'
01101100 l
"''"''""
01100101 e
"''""'"'
00101110\.
""'"'''"
01110100 t
"'''"'""
01111000 x
"''''"""
01110100 t
"'''"'""
[<] #
\ standard concatenation loop with file reading(and EOF check)
`+[-.`+]
Want to give the actual value of the cell when printing? Just add a dot above your intruction!
01100100 \ 'd' or 100
"''""'""
. \ prints "d"
: \ prints "100"
