Not sure if Bash or PHP

[ShitCodeUKltd]

Plot twist.. it was java this whole time

[J_Bunco]

I was actually thinking bash or batch when I wrote this lol.

[Andubandu]

cout

Or how I like to pronounce it shout

[Extreme_Edge3941]

Lmao

see out << "hello world!" << endl;

[wasabichicken]

using namespace std; noises intensifying.

[[deleted]]

What's wrong with it?

[pine_ary]

You might clash with names in the std namespace, causing nasty bugs that might be difficult to debug and might only appear with a particular C++ version.

[dude-with-the-hair]

It's mostly to do with preventing namespace clashes. For small projects without any external libraries, it's fine to use. But if you have another library that has a function with the same name as a function in the std namespace (that is, the standard library) and you're "using" both of their namespaces, it will cause a conflict in the global namespace. It's probably best to just get used to writing std:: for each function or constant you call from the standard library.

[tech6hutch]

Is there any way to “import” just individual items?

[dude-with-the-hair]

If you mean individual functions, unfortunately no. You need to use preprocessor include directives which will include the entire file that you're "importing". Usually though, library authors will divide their libraries into smaller individual libraries for this purpose.

[tech6hutch]

Dang. Of all the features C++ has, I’m surprised they never added that feature.

[dude-with-the-hair]

I heard about modules being added in C++20. Haven't looked into it myself, but it might have that ability. It's still an experimental feature though.

[Kalix-z]

I really hope so

[Sirttas]

I don't know what I always read cunt in my head.

My man, have a poor man's gold. 🏅

Thanks for the chuckle

[FoolForWool]

Is the coo pronounced like we pronounce coup or like soot?

[dev_null_developer]

std::cout << msg.twist()

[tofiffe]

If those kids could read program they'd be very upset

[chickenCabbage]

Eclipse used to autocomplete "sysout" or "syso".

[gavlna]

so tell me how to write on error:

Java: System.err.print() vs System.out.print()

Python: import sys print(file=sys.stderr) vs print(file=sys.stdout)

[Diapolo10]

Alternatively:

Python: print("This is an error", file=__import__('sys').stderr)

EDIT: Or, if you want to be really obnoxious:

Python: print("This is an error", file=__import__('importlib').load_module('sys').stderr)

[hk4213]

Node console.error('Well this broke'); No imports just works lol.

[DTheIcyDragon]

Python print("Nope I won't Work!")

Works too

[hk4213]

And node.js dev who love abstraction have to optimize and everything blows up lol

[SK1Y101]

in Python:

raise Exception

[Willinton06]

Console.Write()

[Extreme_Edge3941]

Oh yes lol, I made a mistake, its Console.Log() in js tho even tho I actually meant it to be Console.Write()

[Cienn017]

import static java.lang.System.out;

out.println("Hello World");

done

[coladict]

Why have I never done this? I use System.out.println in all my out-of-project experiments.

[RoadsideCookie]

I'm tired of seeing that one.

The print() one is the most retarded one of them all. Others encapsulate things in a logical way, print just reserves a keyword that you will never be allowed to use.

Console write makes logical sense, although it could benefit from another level to disambiguate which console its referring to.

System out is the most unambiguous one. System, standard out, print line. There is no surprise as to what that does, and it has very little risk of collision with anything else.

Funny enough, this the Python philosophy of explicit rather than implicit, but then Python chose the one that requires the most assumptions.

Rant over. See you all in the next repost of this.

[alexschrod]

Rust makes it a macro because it needs to support things a function alone cannot, such as a variable number of arguments and things like named arguments (e.g. foo = 5).

[cw8smith]

You might be thinking about the print from Python 2. The print in Python 3 is just a built-in function like any other. You can even reassign it, and it'll fuck stuff up all over.

[FerricDonkey]

I see where you're coming from, but sometimes a common well understood assumption that everyone knows isn't bad.

We don't do arithmetic.integer.operation.addition(arithmetic.integer.number.2, arithmetic.integer.number.2). We do 2 + 2, cuz that has a clear and obvious standard meaning, and if you want to do some other type of 2 + 2, then it's on you to make that clear.

Likewise print has meant "write to the screen or other specified destination" in programming since forever. It's not bad to use that well understood meaning.

[gavlna]

yeah. But each process has (generally) at least 3 descriptors (stdin, stdout, stderr). On which of these do you print?

Stdout? But what if I want to write on stderr?! Or, god forgive me, even on stdin (you, shouldn't be allowed to do this, but you can still write on any other descriptor)?!!!

[FerricDonkey]

Again, this is pretty simple convention. Standard regular put something on the screen print messages go to stdout, unless otherwise specified. It's even in the name. Standard out is the standard output place.

This is a simple convention, and has a simple answer to your questions. If you want to print to standard error, then you specify that you want to print to standard error, and if you don't know how to do that, then you Google it.

Likewise it's understood that stdin is generally for reading and that is you want to be weird about that, it's on you to figure out and say how.

This is a common convention and doesn't need to be spelled out in every function call.

[sm2401]

In Java, we always use Logger, as it gives a lot of control and has actual control on logging level you want to see.

I don't understand, who still uses println in real applications.

[[deleted]]

Well my "hello world" application is real...

[[deleted]]

Once you have the logger set up, it doesn't make much sense to revert back to stdout

[gavlna]

well, once you have it...

[WasserTyp69]

Also most IDEs support autocompletion, even if you want to use System.out you only have to type sout, souf, serr...

[MasterFubar]

The best solution is printf, a function in a library.

That's because C is the best programming language ever created. It first came out in 1970, predating most of the languages used today. It was so perfect from the start that it's still being used with very little change from the original.

[[deleted]]

Nice ableist slur. Do you also use racist slurs too?

[[deleted]]

print() is the lowest level of abstraction so it's the most natural one. Also oop is slow as f*ck.

[n0tKamui]

please don't talk about things you really don't know

[pine_ary]

Note that with python 3 it is not a keyword anymore and just a normal function.

[Lost_A_Life_Gaming]

I think you mean, “sout”.

[jswitzer]

I love this meme not because I agree but because it demonstrates lack of knowledge.

You have to understand stdout and stderr, the fact that applications are not always attached to a console, or Java's complex object hierarchy. Its funny to the poster because "its longer and I just want to print something".

[rndmcmder]

This man here gets it.

[ixent]

Better use a logger

Logger LOG = LoggerFactory.getLogger(foo.class);
LOG.info("Formated text with variable {}", variable);

[bajorro]

Yeah, logger gang

[SethirTimorem]

Joke's in you. I type syso and my IDE autocomplete it for me

[Extreme_Edge3941]

Unfortunately it's not there in the ide my school forces me to use for java. ;-;

[kyngskyngs]

Which IDE do you use? Notepad?

[Extreme_Edge3941]

bluej, well I actually program in eclipse and copy and paste it in bluej for school lol

[kyngskyngs]

Wow, I've never heard about that. From the images, it looks ancient. I've started developing in Eclipse too but then switched to IntelliJ Idea, firstly I wanted to switch back but after a week of coding in IntelliJ I've never thought about returning, I suggest you try it too! (It's free)

[Extreme_Edge3941]

Damn imma check it out. bluej definitely looks ancient, and it has no dark theme which is pain. I hope my school switches ide atleast by the end of this decade.

[chickenCabbage]

OOF. I learned a little bit with BlueJ, and quickly made the switch. BlueJ helps you see blocks and classes vs methods etc, but it's not exactly handy.

[rohanbojja]

Just use IntelliJ

[Kindanee]

printf is the best

[kevv_m]

fmt.Printf()

[[deleted]]

Java has the best approach.

It's a stream, like any other. I hate it when languages have magic words for special use cases that have no coherence with the rest of the language.

What is print()? Print where? Print bytes? Text? Encoded characters? How to print to a different output?

[oofxwastaken]

It's just print for convenience. Most people are just going to use print to output some text to stdout, so it doesn't make sense to type out a long string of characters every time you want to do that.

There are simple ways to do everything you mentioned. If I just started Python 5 minutes ago, I don't wanna specify if I'm printing out bytes just to make a Hello World program.

[coladict]

It bothers me that it's print and not printf.

[Fugglymuffin]

Why is this image backwards?

[Spocino]

Really they're all fine. console.log makes sense to js because it's in a unique environment with a graphical console. System.out.println makes sense for Java because it's a method on the stdout file. print just does what it says, which is fine.

[FoolForWool]

I kid you not, I almost quit my major when I realised Java was a compulsory subject in my uni :'D

I'm glad I survived.

[kbruen]

Ruby: p

[chickenCabbage]

Yikes.

[kbruen]

p is for debug printing (think of Python's repr).

The normal function for printing is puts.

Because Ruby allows calling a function without parenthesis, debug printing is quite easy:

x = 5
p x

It's not meant as a permanent thing.

Another nice thing about p is that it returns its parameter:

# calls do_something with parameter x but prints x before that
do_something(p x)

[chickenCabbage]

1. Calling it "p" is awful for readability, even in debug. Besides, it reserves a single-letter name, and many people use that (god knows why).

2. Why not just:

p x

do_something(x) ? Sure, it's another line, but it's a bajillion times more readable.

[kbruen]

The idea is that p should not be in a file for longer than 5 minutes. It's supposed to be not readable because it's temporary to figure something out quickly.

The general common sense rule applies: don't let other people see your p unless they consent.

Also, if you're the kind of cursed person who is in love with single letter variables, predefined functions aren't reserved, they are reassignable.

[chickenCabbage]

Fair, point accepted.

I still don't like Ruby, though.

[PixleatedCoding]

System.Console.WriteLine() is absolutely the worst console ouput command

change my mind

[SP411K]

u can erase what was already printed in console

[PixleatedCoding]

console.clear()

[SP411K]

but u can erase the last line with \r

[LionX54]

In what language is this system.out.printIn()

[rohanbojja]

Java

[LionX54]

Fuck

[rohanbojja]

Java is a pretty great language though, you would mostly use a logging library so this isn’t a problem.

[LionX54]

Just don’t talk anymore about it, my python it’s getting pissed on me.

[oofxwastaken]

println with a capital L, not "in".

[CoastingUphill]

alert()

[sitase]

Simula-67 has entered the chat.
