4 Delvs(Pronounced Del-vis) is my own personal variation of brainfuck, the interpreter is written in C.
|
|
|
5 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)

9 - `:` casts the current value to a string and prints it. Code: `printf("%hhd", *p);`
|
|
|
10 - `;` grabs value from user input and casts to cell value. Code: `scanf("%hhd", p);`
|
|
|
11 - `#` 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. Code: `f = fopen(p + 1, p == 1 ? "w" : "r");`
|
|
|
12 - `` ` `` read next char from file, apply to current cell. (`EOF` becomes `0`) Code: `*p = fgetc(f);`
|
|
|
13 - `!` write char from current cell to file. Code: `fputc(*p, f);`
|
|
|
14 - `"` increment current bit position by 1. (psuedo)Code: `b++;`
|
|
|
15 - `'` flip bit at current bit position, then incrment current bit position by 1. Code: `*p ^= (1 << b)`
|
|
|
16 - `\ ...` ignore EVERYTHING until newline is reached. `while(*c) if(*c++ == '\') return;`
|
|
|
17 - `@` prints value of current cell and surrounding 4 cells. Code:
|
|
|
18 - `$` sleeps the current cell's value in seconds

20 ### To do
|
|
|
21 - implement a working socket system
|
|
|
22 - implement an stdout flushing system
|
|
|
23 - implement runtime args
|
|
|
24 - implement namespaces(seperate arrays of 30000 chars)
|
|
|
25 - (maybe) implement better way to divide
|
|
|
26 - implement full integers
|
|
|

|
|
30 Setting entire cell values with just the bit intructions is as easy as converting 0's to `"`s and 1's to `'`s.

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

59 How about reading files? Just generate a string as the filename an the use a `#` at the beginning of it. Like so:
|
|
|

|
|
|
61 01101101 m
|
|
|
62 "''"''"'

64 "''''""'

65 01110100 t

94 Want to give the actual value of the cell when printing? Just add a dot above your intruction!
|
|
|
95
|
|

96 01100100 \ 'd' or 100
