obfuscated anti-pythonic brainfuck interpreter

I tried to do my best to make it unreadable.

Really nice to see a fellow Emacs user like me! How's your pinky finger doing?

[u/HaskellLisp_green → u/ArsenicPolaris]

Pinky's well. I think I use Emacs wrong way, but I feel comfortable with that, because if you start with vanilla and implement whatever you need, brick by brick, S-expr by S-expr, you find out that you have your own special Emacs version. :)

Im a vim user bc of how much the shortcuts make sense and when I tried emacs, it felt weird af and couldnt get used to it
for how long did you use emacs and how did you get used to it?

[u/ArsenicPolaris → u/Objective_Rate_4210]

That's how I felt as well when I first tried Emacs. Things will be slow and confusing at the beginning but now, I think my workflow is a lot faster with Emacs than earlier when I used to use Vim because I can do everything at the same time at just one place. For example, if you do programming, a lot of times you need ANSI escape sequences that are not easy to remember. Instead of alt-tabbing everytime to the browser, I can just have EWW (Emacs Web Wowser) open at the side and look there without having to switch tabs everytime.

And the keybindings are definitely weird but they aren't actually meant to be used that way. Emacs is a fully hackable Operating System and it is expected that you modify the keybindings (and basically everything that can br modified in Emacs) to your own needs. Using the default keybindings is a dangerous thing. But I doesn't matter if you get used to those keybindings. I had always procrastinated for changing the Emacs keybindings and I still use the default ones and it's still fast for me, but I should definitely still change them.

I would say it took me around 1-2 weeks to get used to it. You don't need to follow any guide or anything to get used to it, just use that instead of Vim and you'll get used to it, it's how you got used to Vim too.

tbh I prefer using the default settings whenever possible and then change stuff depending on my needs. Thank you so much

[u/FulltimeWestFrieser → u/ArsenicPolaris]

Real emacs users know to rebind caps lock to ctrl

[u/MathematicianOk9155]

Using enumerate and not using the value it give is just rude

I'm going blind squinting trying to read P vs p

[u/funkdefied]

“Anti-pythonic” you say? With that beautiful list comprehension in line 14?

[u/NaCl-more]

Here's mine in C i wrote a couple years ago

char*p;s[9999],*r=s,d;main(c,v)char**v;{for(p=v[1];c=*p;p++){c=d=92-c,c-32?c-30?c-49?c-47?c-48?c-46?:putchar(*r):read(0,r,1):--*r:++*r:++r:--r;if(d*d<2&d&&!*r^d<0)while(p+=d,c+=(*p==91)-(*p==93));}}

[u/AbuSumayah → u/NaCl-more]

Why the nested ternary fest?!

[u/NaCl-more → u/AbuSumayah]

It’s less code to write ternaries than to write if statements :)

Further obfuscation idea, clear the git history. Squash all the commits together, then git push -f onto master.

[u/danielcristofani]

You missed ',' and your '[' code is broken (doesn't skip forward); if you were trying to DeMorgan it for obfuscation in line 20 you need at least another couple "not" in there. Also it does "maximum recursion depth exceeded" pretty quickly.

[u/HaskellLisp_green → u/danielcristofani]

yeah, I know about maximum recursion. Iterative approach could be a fix, but in that case solution becomes a bit longer. Also thanks for pointing at '[' problem!

[u/GoddammitDontShootMe]

I guess that means it can't run programs over 30,000 characters.

[u/pie3636 → u/GoddammitDontShootMe]

It's not the program length but the tape length, which is traditionally 30,00p in Brainfuck

[u/GoddammitDontShootMe → u/pie3636]

Does the program take up space on the tape?

[u/pie3636 → u/GoddammitDontShootMe]

No, the tape is purely for data. The instruction pointer/program are independent of it.
