Title: Yet Another Brainf*ck Text Editor
Post by: AngelFish on August 22, 2011, 08:55:48 pm

Introducing the future of text editors, the Tidal editor. Hand-written in raw, optimized Brainf*ck (after being ported from both the TI-84+ and Casio FX-CG families of calculators) and released under a GPL license for this exclusive beta download, Tidal is the fastest and most powerful Brainf*ck text editor around.

The text editor core is like five instructions :P

The rest of that is just parsing inputs.

Way to go Qwerty, it works great. I typed it into my on-calc BrainF*ck compiler and it worked great. The only problem was that I had no way to type ~, and I feel like half the code is devoted to backspacing...

It's actually pretty long if you type it out. It took 8 full lines in the basic editor.

Yeah, the equality test I used for ~ is... slightly long. But if you want to replace "~" with your own value, just change this part of the code to generate the character value you want:

Code: [Select]

+++ ++++[<+++ +++ +++>-]<[<++>-] That's set to 0x7E or 126 in the regular code. The test works for any value.

On a side note, I still have features planned for this simply to see if I can implement them :D

I made it use 'z' = 0x7A by simply adding -- right before the final [<++>-]. But then nothing changed.

So I debugged the whole thing and I saw the magic in action. It was so cool to see the whole thing work out perfectly and end with 00's. But what I saw is that it doesn't actually update the screen, it just deletes the memory. So now I know.

There are a few interpreter oddities that make refreshing the screen a PITA to do consistently, so that's one of the things I want to figure out next.

This is incredible. HOW DO YOU DO THIS.

I went back and commented the source for anyone who's curious about how the magic happens. There might be a few minor errors because I lost the original (commented) source to this, so I had to figure out what was going on again.

Code: [Select]

+[-,> // notice the similarities of this code to the main interpreter loop code of "+[-,>+]"
     , // handle the \n most editors insert after input where the character code for \n is 0x10
   ----------[++++++++++>] // subtract 0x10 from second cell. If still non-zero (for multi-character input),
          // restore it and switch to next cll
          [-] // zero the value of the cell to operate on (to handle bad interpreter memory initialization)
           [<]< // go backwards to the last character entered
            [>+>+<<-]+>-[<+>-] // copy character entered out to next two cells
            >>>>+++++++[<+++++++++>-]<[<++>-]<< // the character code for "~" is 0x7E which can be factored as 7*9*2
                 [>-<-]> // subtract the character code from 126
                 [>>]<< // if 0, move pointer back to value of character in memory
                    // otherwise nothing happens
                 [-]<  // erase value of cell containing previous character code (if current code is 0x7E)
                 [-]<+ // clean up memory normally

You type the code and it does stuff. In cases like this, sometimes cool stuff.

what's Brainf*ck?

The classic Esoteric Language (basically, a language that exists either as a joke or to challenge programmers), that has a tendency to F*ck your Brain. Hence, the fitting name :)
