We are absolutely in agreement.
Personally I would side against overloading operators unless the meaning is intuitively obvious, e.g. +-*/ for arithmetic classes and [] for container classes. As soon as you have to ask "what does this mean for this class...?" then you're doing it wrong, because operators ideally have a globally consistent meaning.

i-i have done it. i have become faggot.

>Rustacean
I get having a CoC and forcing niceness. I get not being 100% serious in your docs. But stop with this shit in the official manual, for fuck's sake.

Today I learned Rust has a pseudo-goto in the form of break label. You can add a label to a loop to allow break to exit out of an inner loop. Combined with using RAII for deterministic cleanup of resources upon an error, Rust has effectively eliminated every legitimate need for a goto using other language constructs.

>>60373890

If you're looking to use another programming language as an intermediary language, I'd recommend not using Rust. Presumably, the compiler you are using to generate the IL will always produce correct code, so using a language with an advanced type checker will only slow down compilation time (the type checking should be done in the language you are transpiling to C). Moreover, Rust only supports as many platforms as LLVM does, while C supports at least as many targets as LLVM does, with compilers on other platforms as well.

>>60374102
for a quick n dirty DSL, typechecking in the target language might be more time effective.

Continuation from >>60373433 (posted 5 mins before thread died).
Does anyone here have any experience in going from OOP -> DOD?
In which case, do you have any tips or experiences you'd like to share?

Context:
I'm a C++ game dev, that has recently taken an interest in trying an entity system rather than the conventional component-based design.

Just to annoy you guys, I intentionally added a goto into the SW project I’m currently working on. For the first time in my life. It was a very peculiar feeling, like shitting on the desk. (hmm… haven’t tried that yet) My fingers are still trembling, I feel guilty and depressed. I lost something, I’m not myself anymore, my guilt is chasing me. I believe they’re watching me during coding. Heard some strange remarks about me around the coffee machine, they probably know it. Trying to act normal, but it’s probably written on my face. I’m afraid that my boss will see that code and tells me down in front of the team. I would not survive that. Probably will be called “the goto guy” in the rest of my life. Not sure whether I can carry this weight, I regret doing that in the same minute. I wish I could change history, but it’s already committed. Everytime I open Mercurial, I get shocked by that change set with the ugly goto, like touching high voltage.

It seems that the only way out is setjmp.h. That would end the pain and I could be free again. I don’t want to be the average conformist coder, adding auxiliary variables to keep the state or restructuring all those five code lines, just to make my manager happy. I’m not broken yet, I still have self esteem. Probably if I add some Inline assembler, they won’t notice the goto…

>>60374414
>Just to annoy you guys

not like we give a shit, you're the one that will have to maintain it

>>60374139

I can't think of any reason why you'd get a speedup using another language's type checker, but I can think of a practical reason why not to. Namely, that a type checker is supposed to be a sign of code that is broken. How can you know what is wrong with your own program if the error message is in code generated by the compiler?

Perhaps, but I'd figure if you want to make a DSL people would like to use, it might make more sense to put a little more effort into designing it, especially if performance is so relevant to its usage that it needs to be compiled, rather than interpreted or embedded within another language.

>Again, this is in no way an optimal way to make a DSL, but
Eh, I suppose you could do things like that, but it wouldn't be able to give you a detailed reason for the error.

>>60373589

>>60374496
I'm not sure what you're asking, but if you don't know what I mean by "conventional component-based design", I'm simply talking about a Component system.

In a component system, the functionality of game objects are split up into smaller components, that are then have to be attached to this empty shell. This is, for example, what the unity engine is based on.

An ECS, or an Entity System simply takes this a bit further by being more data centric and maximising the efficiency of the cache. (( though there are obvious downsides, such as a lack of abstraction and difficulty debugging etc.))

>>60374832

It's nice in certain scripting languages e.g. PHP where funny things happen to double-quoted strings.

>>60374766
this does the opposite of what you think it does.

>>60374876

In Ruby, single quoted strings are faster to parse, because you can't do string interpolation with them, and most escape sequences are more or less interpreted literally.

If you want to do different things depending on where the exception is thrown, you need separate try blocks.

Generics are a mistake and the world is starting to understand this and turn away from them.

The usual argument for generics is to avoid writing "boilerplate." But understanding the details of how the code actually executes is vitally important to understanding what the program does.

I need some naming advice. Please keep in mind that English is not my first language.

I'm writing simple support for different units and types of measurements - weight, length, arbitrary "custom" units and so on. I have no idea what to name it all.

Let's say we have concepts of measurement, like "length", "weight", "volume" and so on. Then within "weight" we have "grammes", "kilograms" and so on.

What do I call the classes of these? I'm thinking an enum/class for "Measurement" which describes measurement types like length and volume. Then one metre is a unit of measurement, so therefore the class which describes "metres" or "kilos" should be called "Unit" ?

Are there better names I'm missing here?

Not really.
I think measurement fits better.

I have a very stupid question, what happens if i don't specify the headers argument when calling requests.get in python? I just give it the url. I see it works anyway, am i right? I'm using it in a script that monitors a webpage for changes

Hello, I have just done this:
#include <stdio.h>
#include <stdlib.h>

int main()
{
char arr[12] = {' ',' ',' ',' ',' ',' ',' ',' ',' ',' ',' ',' '};
int i, e;
for(e = 0; e < 12; e++)
{
for(i = 0; i < 12; i++)
{
printf("%c", arr[i]);
}
arr[e] = 'H';
arr[e - 1] = ' ';
printf("\n");
system("CLS");
}

return 0;
}
The idea is make the H move from the first position to the last one. But it does too quickly.
How do I make the first for wait a second until runing again?

Game dev is the same as regular dev except you get paid less and have shit hours. A software engineer working on a game isn't going to be doing cool video game stuff, they are going to be optimizing a task scheduler or hunting down cache misses.

You could make it so that instead of choosing only one input at random, it chooses n at random, for n <= input size.

Dimensions.

Look up the IUPAC Green Book, which goes through some dimensional analysis with the common physical and chemical dimensions.

By the way, 'gram' and 'kilogram' are not units of weight.

>>60377991
Unless you're an indie game dev. Then it's shit hours, inconsistent pay but generally beans, and nothing at all like regular dev.

Python pleb here, Rust looks interesting. Is there any book I should read as an intermediate programmer?

>>60377932
GNU shuf does a better job of this than your program. You probably store all these lines and select a random one at the end. Make this a true CLI app, that understands EOF and doesn't pollute the output you might use in a pipeline with diagnostic messages. Make it accept a parameter (-n) that tells how many random lines to output. Make it work when the input is bigger than your memory. Implement the rest of GNU shuf, without looking at its source.

The CLI is something you might think you are familiar with.

>>60378301
Rust essentials, or the official Rust book online

>>60377932
>>60378315

Also when you are done, try timing your app and GNU shuf. If yours is faster in multiple cases, send them a patch, though I doubt that would happen.

Wrote a python script today that replaces non-ascii characters in a filename by either a suitable equivalent (like ae for ä or ... for …) or its escape sequence, because some other programs had problems with non-ascii characters previously, but they're ubiquitious.

Disagree. Consider:
>I didn't really read your mindless post.
This implies previous participation in the conversation, because if he hadn't been participating, there'd be no reason for him to say he didn't read my post, because no one expected him to.
>As I expected.
This also implies previous participation in the conversation. The implication is much more obvious and warrants no explanation.
>Only those who belong to this species are human beings. The implication is pretty obvious.
The implication is scientifically inaccurate. I maintain this inaccuracy is deliberate as a kind of exaggeration. Implying anyone is less than human as a form of exaggeration is morally repulsive and ergo a demonstration of my point.
>"this" doesn't refer to the sentence itself.
I know it doesn't. But it does if you take it out of context. It was a joke, you see. Pretending to have absentmindedly abandoned the context of a conversation is funny. It's like a verbal slapstick.

He claimed that killing is the ultimate expression of humanity. Humanity is generally a trait held in high regard. An expression of it would therefore be desirable. His claim therefore entails that killing is desirable.
>Not in any English-speaking culture I know of. Maybe in your lost cause of a country it implies something.
It's not a matter of language. Such a response would carry the implication I claim it carries in any dialect of English, as well as Spanish, German, or Chinese.
>Ah, so you were only pretending to be retarded.
Clearly we don't share the same sense of humor.
>It is entirely accurate. I have actually studied your kind pretty thoroughly and I have concluded that there is simply no way you belong to the same species as the rest of us. We could meet somewhere and I could show you my research. But only under the condition that it will be in some neutral land which hasn't been infested by your kind yet.
You're talking out your ass. No, wait--this is worse than talking out your ass. You're writing absurdist science fiction. I'm not interested in your research, because it doesn't exist, and is part of a silly children's game you've invented in a desperate ploy to win this ridiculous excuse for a debate, and I'm in no mood for games.

"1_based_string" is not even a valid identifier as it starts with a digit.

Yes, and n should be '\n'. I fucked up formatting when I uploaded it. Sorry.

Hi.

>to which that sentence was intended as a response
But this is wrong. If it's not, then it should be easy to demonstrate. Yet you failed miserably at such a "simple" (according to you) task.
>Humanity is generally a trait held in high regard.
Can you link me to the post where he said he holds humanity in a high regard?
>An expression of it would therefore be desirable.
Only assuming he actually holds it in high regard. Which you can't possibly show.
>His claim therefore entails that killing is desirable.
Even if he somehow thinks it's desirable, his statement isn't an endorsement of it.

>It's not a matter of language.
Yes, I was wrong. It's a matter of species.
>Clearly we don't share the same sense of humor.
Indeed. I don't find saying blatantly wrong things to be funny. You seem to though.
>I'm not interested in your research
So you're not interested in the truth about yourself? That's nothing surprising.
>because it doesn't exist
It does. I could show it to you if you agree to meet me in a country which isn't entirely ran by the world police.
>I'm in no mood for games.
You seem to be, since you basically deny your own identity. How is that not a game?

Jesus Christ you've JUST learned this? break has been a thing since c++

I didn't expect a coherent answer from you anyway. It's not like you're even physically capable of delivering one.

>>60380447
On the contrary, that statement is more applicable to yourself. The sort of reduction of semantics to first principles you constantly demand is beyond the scope of any discussion worth having, and of no interest to anyone who can read. It's like talking to a brick wall. I'll have no more of it.

>that statement is more applicable to yourself.
Since I'm human there is nothing stopping me from being able to in principle construct a coherent response to any of your retardation. You on the other hand have a severe handicap, so I'm not expecting much here.
>The sort of reduction of semantics to first principles
Also known as actually referring to things that happened and not your retarded and misguided interpretation of them.
>It's like talking to a brick wall
I highly doubt a brick wall can offer you insights into your own nature. That would be pretty helpful, since currently you just outright deny reality.
