Don't be autistic. You know what I meant.

Only an ai bot would write such a switch statement

>>105762799
Nah, AI chat bots usually use the most boring formatting and alignment possible. I usually format code by hand so it's easily readable and I can look at it and quickly see patterns.

What's thr best way to learn asm?

>>105763647
why would you want to learn assembly?
once you have a good understanding of C, assembly is just useless mental gymnastics made obsolete by any compiler or godbolt if you prefer a web interface

>>105763647
reading lots of assembly code, unfortunately

>>105763687

I'm just very irrational with my choices of what to learn, don't care about utility and I mostly go with what feels maxxcomfy but also weird at the same time.

its interesting and not everyone wants to be a codemonkey

>>105764036
it's not fucking interesting
if you actually gave a fuck about such "interesting" shit, you would implement your own virtual machine with your own register layout and whatever other weird shit you want to include, and you would consult existing architectures in the process. this would teach you a whole fucking lot more than any bullshit fucking around in x86 ASM as if you're doing anything of fucking value.
build actual fucking software that does interesting shit. that is the point of programming. not fucking around like some monk "speaking the language of the chip." it's fucking stupid as absolute shit.

>>105763687
>why would you want to learn
If you don't find joy in learning and understanding how things work you're some variety of nigger, pure and simple.

>>105764105
learning assembly is like learning multipication by memorizing every possible combination. sure its good to memorize any X*Y=Z for X and Z < 20. but to memorize more than that is not "learning and understanding" its just stupid.
same with assembler. you need to know the basics, whats a jump, branch, comp, etc. but memorizing 500+ mnemonics is, well just stupid. you'll learn anyway, if you have to work with them.

>>105764036

>>105762446 (OP)
Why would you write switch statements like that? Are you scared of new lines?

well he puts the bracket on the same line as the statement so, clearly.

>>105762446 (OP)
>enum
why

>>105762446 (OP)
why are you using braces around the switch if you're already disgustingly hiding it back there

>>105767343
why not? what would you do? use a number to indicate mode / direction? thats the same thing but you've just lost the name which is nice to have for clarity

My fav pattern for fsm state functions.

>>105769558
i always make my switch case statements 1 liners. If the body cannot be squished into 1 line then i'll make it a function. I just love seeing
switch(X)
{
case A: ... ; break;
case B: ... ; break;
case C: ... ; break;
case D: ... ; break;
}


so clean

>>105769574
There's a satisfying aesthetic to it for sure.

>>105762446 (OP)
stop being such a special princess and format your code properly.

>>105769574
at that point you might as well make have a static const jumptable and just call it like myfunctions[case]();

>>105770030
i sometimes think about doing that but im not sure because the compiler can probably more easily interpret what im doing with a switch statement and so it can figure out whether to turn it into a literal jump table like that or not

then again im not sure the compiler will ever make a jump table if the case values are not consecutive

>OP said comfy, not 200 line function

>>105767325
I try to keep code under 80 chars, not because of some kind of autistic compulsion (well, maybe a little bit of it), but mostly because it's obviously easy for humans to comprehend information when it isn't stretched all over the screen and looks more like a newspaper column. So yeah, it does save space on the left inside the switch statement. But also it just makes sense to do it that way because it indicates immediately that the "if" only applies to "switch" and there's nothing else inside besides it.

>>105771374
I can't take seriously people who writes test code or TDD promoters.

>>105770612
I've never done this before until recently, then decided to try. It's super comfy and actually useful, because you can immediately see what's tested and don't need to jump between files abd serch for unit tests. Also when you do it this way, there's no need to name your tests, because it's immediately obvious which function they're testing - the one they immediately follow.

>>105771981
I don't promote TDD but not writing unit tests and not understanding why it is helpful both immediately and in the long term is very much a skill issue.

>>105772005
So, you need something to take your hand and guide you because you are not able to understand your own code and how it can potentially fail.

>>105770017
Whoa buddy, it's my code, it doesn't owe you any formatting. If you use go fmt or whatever equivalent - good for you, but I bet you're one of them people who cannot picture an apple in their heads or something. Many such cases.

>>105772032
You got it wrong. Say I'm writing a gui app, but this particular part is far removed from actual gui. Unit tests just make it possible to write without a) having gui part ready first b) having to constantly check said gui after every change to my code. If you claim you can just write any kind of code and make it immediately work, you're talking out of your ass.

The formatting is nice.

>>105774118
I think it's actually the font that makes it nice, haven't found a better one in years, desu.

Not mine but look at this beauty.

I think it's clear that way

Where? It says step >= 1, not step > 0
> both getter and setter
Don't think so, this is D. If you mean that function is reloaded with different (0 and 1) number of args, then yeah. This actually allows me to say obj.mode and obj.mode = and is intended.
> pausing twice
Good catch

>>105774272

Not a particularly elegant function as a whole, but it calculates the screen-space extents of a cube using just 4 AVX intrinsics at lines 30-33. What normally takes 8 mat4-vec4 multiplications compressed to one.

for 100000 elements arrays.
This only happens in certain adapters like you have read in the documentation. In your code where you just do slice::iter().enumerate() it literally won't make any difference and you are just making your code super ugly for no good reason.

>>105775346
>super ugly
why do you consider that style ugly? with a normal ass for you have to look at surrounding variables to determine intent. a fold guarantees that you are combining a collection into some other variable.
it's literally just a matter of you learning how to read the functional style.

>>105775362
>why do you consider that style ugly?
For the same reason why LISP is ugly. It's just symbol soup that is hard to follow. For loops with proper flow control keywords are much more clean to look at than nested, multi-line closures.

>>105775671
it's hard to read because you are not used to it.
it's genuinely that simple.
do you think people that enjoy Lisp are just bullshitting when they say that the syntax is nice? no, they've put in their week of time with the syntax, internalized it, and began to cringe whenever they had to do superfluous bullshit when using another language.
here is a Lisp that I made, it does not allow for variadic arguments, so you do not need parentheses even.

hashmaps are so retarded of a concept i didnt even have a word for that type of structure until i was years into programming in c

>>105777157

i really dont look like a programmer irl, though
im a dropout, self taught
i was a physical worker during my whole wagie career
i done my programming heresies during the night

If I may interject for a moment what you're refering to as a hashmap is actually a lookup table or as I've taken to calling it a 2 + dimensional array available for lookup.

>>105777233

>>105777103
>hashmaps are so retarded of a concept
this is a joke post, right?

>>105777341
i meant its basic
for me its just memory management
you figure out storage structures and interfaces to streamline the access to your data
i could take a function that atois a string into an int and then shove that into linked lists and make it live in arenas and you would say "thats a hashmap"
well, not in my mind
its an interface, and memory management in the larger sense
its not specific to your hasmap, it extends throughout the whole program

>>105777375
post your code

>>105777268
>>105777375
(cont)
i mean
lets say you work with a big array
lets say you create a LUT to elements in your big array
lets say its for a game and you have an additional layer of abstraction, your scripting language
and you use that look up table to access the data of your game, idk, positional for ex
and that you have a function that turns a game id into a number which is then used for indexation

where does the hashmap starts and where does it end?
it there even one at all? because for me its just the interaction bw different subsystems
interfaces and memory management

>>105777375
>i could take a function that atois a string into an int and then shove that into linked lists and make it live in arenas and you would say "thats a hashmap"
I wouldn't, actually, because it has no bucketing, collision behavior, and atoi is not a good hash function
