rust is made by mozilla webfags because C/C++ is too hard for them so they need something """"safer""""

but rust is like a retarded version of C++, it offers no tangible benefits over C++ and it's much less popular (which matters when you need to find people to work on your team)

Will C and ASM save america from niggers and cucks?

>>59008822
Rust is like a redesign of C++ with some 30 years of hindsight. A lot of /g/ hates it because /g/ is full of people who like to roleplay as expert programmers and feel validated by writing their fizzbuzz programs in an unsafe language, see: >>59009012

>>59009012
modules instead of retarded header system from the 70s
algebraic data types
hygenic macros
pattern matching
immutability by default instead of spamming const everywhere (or not)
traits (which C++ has been trying to add in the form of concepts for the past decade without success)

Really, you should have just stuck with the usual cucks/sjw mantra instead of trying to make a substantive post. No one can argue any facts that way.

>>59009168
The problem with rust is it will take them 5 more years to get Non-Lexical Lifetimes, if we're lucky.
And in the meantime it's pushing a lot of people away, because correct code that ought to work is rejected for no reason by the compiler.

the syntax alone is enough to repulse people

>>59009194
>5 more years to get Non-Lexical Lifetimes,

What makes you think it's going to take that long? From what I've read that was largely the goal changing their IR from LLVM's default and they've already accomplished that. I didn't have the impression it was far off.

I agree it drove me away. Fighting with the borrow checker where I knew I was in the right drove me to learn C++.

Only the fools who are afraid of anything they don't already know.

>>59009012

>>59009228
>>59009235
come on, it's on par with C++ at best, and C++ is not a pretty-looking language, if they wanted to come up with a substantial improvement they could have made a better syntax

>>59009234
It might sound pessimistic, but I'm afraid it might not be too far off, NLLs in rust is a very non-trivial goal.

First the design itself is far from settled, even though the problem is already more than four years old and very well known at this point.
Then there's the fact that it's a surprisingly deep change to the language (and the compiler), with many prerequisites that are just starting to come together, among those the new MIR work.
And finally it doesn't seem to be a priority in the roadmap, even today. More of an afterthought that received far too little attention to hope for significant progress.

>>59009266
Rust started off largely as an ML derivative but supposedly the designer chose C style syntax for popular appeal and ended up with the current puke. It's inappropriate for a lot of the intended semantics of the language. C++ programmers don't have any ground to complain about syntax but some of the especially functional style Rust is ugly on a whole different level and just degrades into a mess of curly braces, parens and vertical bars

>>59009266
Rust is a bit more complex than C++

Even printing a line takes a macro. But Rust is a good language, the new languages will be influenced by Rust

Rust is still better than C++

>>59009335
>Even printing a line takes a macro.

I think most people would rate that better than the streams API.

>>59009412
This is correct.

Thanks, I will!

>>59009596
Good for you, you must be the only one.
Because everyone who doesn't care about performance and predictable behavior is already using python.

>>59009620
I think it has better performance than C#

>>59009639
Then you need to look at the benchmarks.

>>59009639
you may as well use java/C# if you don't care about GC and being several times slower than C

Why do people defend C++ when Ada is better in every way?

>>59009746

Best c++ IDE?

i just want C with namespaces tbqh

It doesn't matter.
If you like your language, stick to it and make programs with it

>>59009813
eclipse

Why do programs like atom crash on large files?
What's wrong, it's just a text editor.

I'm trying to make my own text editor and I have to know what causes things simple as text editros to crash?

>>59009789
12 lines, still readable:

public class FizzBuzz {
    public static void main(String[] args) {
        final String EMPTY = "";
        for (int i = 1; i <= 100; i++) {
            String value = EMPTY;
            if (i % 3 == 0) value += "Fizz";
            if (i % 5 == 0) value += "Buzz";
            if (value == EMPTY) value += i;
            System.out.println(value);
        }
    }
}

16 lines, and really calling for some extra blank lines:

with Ada.Integer_Text_IO;
with Ada.Text_IO;
procedure FizzBuzz is
begin
   for i in 1 .. 100 loop
      Ada.Integer_Text_IO.Put (i);
      if i rem 15 = 0 then
         Ada.Text_IO.Put (" FizzBuzz");
      elsif i rem 5 = 0 then
         Ada.Text_IO.Put (" Buzz");
      elsif i rem 3 = 0 then
         Ada.Text_IO.Put (" Fizz"); 
      end if;    
      Ada.Text_IO.Skip_Line;
   end loop;
end FizzBuzz;

>>59009860
It's a browser my man.

>>59009764
What the fuck does that even mean? You know what's verbose? Fucking C, where every other line is an if statement making sure you didn't crash.

>>59009815
Namespaces are a useless feature that just fucks with C's simple ABI.
Although, C technically does have namespaces, just not in the way you're probably thinking of.

>>59009873
Error checking is required in literally every language.
And if you'd ever looked at the IOCCC you'd know C is one of the most compact languages around, when it needs to be.

>>59009878
You made that exact same post like a week ago, are you a bot?

I want to fork https://github.com/limetext/lime

>>59009905
Almost all other languages don't need it to the extent c does and the goal of making a program small isn't a good goal in the first place.

>>59009868
That's so cherry picked you deserve a (You)

>>59009868

That's cheating, you douchebag.
Although I can agree that both Ada and Java are shit.

>>59009994

>>59009976
>That's so cherry picked you deserve a (You)
Thank you, it was pretty cherry-picked tbqh.
Still, Ada is pretty verbose.

>>59010009
>if (i % 3 == 0) value += "Fizz";
That is supposed to be

if (i % 3 == 0)
    value += "Fizz";

and if you really want to have a fair comparison with the Ada example, it should be

if (i % 3 == 0) {
    value += "Fizz";
}

>>59010009
Put in a
[use Ada.Text_IO]
And then putting the prints in one line just like the Java well like just fine. Use put_line instead of put and remove the integer_text_io import since it's not useful. Wow, I think that makes it shorter than the Java version and better more readable.

Is x86 assembly difficult to learn?

>>59009868
Isn't the Ada version wrong though? You're not supposed to output the number when the Fizz/Buzz conditions are met.

lol. it should at least be possible to refactor namespace-emulating prefixes conveniently using the IDE. maybe vim/emacs has a plugin for that, idk

I haven't started yet, still thinking about how to go about it. I want to add a feature to nemo (cinnamon's file manager) so that you can list directories in the cwd by size, as a file property column. The tricky part will be making sure that this feature doesn't kill responsiveness.
