The 2nd Monitor

You can do ibanElement.setText(ibanNumber), but that's just a syntax-sugar thing

otherwise, no, it looks about right.

Monking.btw

if you knew what was happening behind the scenes you would think it was simple already

No factory method that can create an element based on name and content? :(

11:23 AM

compare it with DOM ;-)

JDOM decided against the Factory method thing. There are too many possible ways the factory methods would need to be done, and there's always utility methods, and constructors

@skiwi Monking too

So i need to ~~lie~~ live with it :)

Or write your own (small) factory method if you do it a lot.

in fairness, you have 6 lines of code populating an entire 3-level XML document....

Yeah

Evil XMLOutputter.output, it doesn't close my FileWriter

it is not supposed to, and it is documented.

@rolfl That sounded a bit too cryptic

11:29 AM

@MadaraUchiha statics aren't that different from instance methods, esp. from a historical perspective

evil user does not read docs:

> All of the output*(...) methods will flush the destination Writer or OutputStream before returning, and none of them will close() the destination.

in php 5.2 you could declare a method and then call it as either a static or instance method

I know... I should've RTFM

jdom.org/docs/apidocs/org/jdom2/output/XMLOutputter.html

@DaggNabbit Statics and instance methods are completely different.

There is no difference between static methods and normal functions.

11:30 AM

and when you did call it as a static method it would even keep the last $this binding

@DaggNabbit There's a very good reason why this isn't the case anymore.

Q: Assign XSLT file to an XML file inside another XSLT?

I wrote an mymap.XSLT file that transforms xmlA.xml to xmlB.xml It renames some nodes, and removes some nodes from the xmlA. I also have a viewBasHTML.xslt that enables viewing xmlB.xml nicely in a browser. I would like to modify mymap.XSLT file so that each resulting xmlB.xml file includes a ...

xml xslt

of course there's a good reason

try {
    xmlOutputter.output(document, Files.newBufferedWriter(path.resolve("manual.xml")));
} catch (IOException ex) {
    throw new UncheckedIOException(ex);
}

Statics aren't OO. They aren't a part of the OOP paradigm, and they shouldn't be used in OO code.

11:31 AM

@rolfl But it looked so nice like this

my point is, historically, there really wasn't much of a difference between static methods and instance methods, internally

Refactoring time then

poor @skiwi

a method was a function associated with a class. if you called it from an instance of a class it would have a $this binding

oh well...

11:32 AM

@DaggNabbit How does that reduce anything from this?

38 mins ago, by Madara Uchiha

There is no single good use-case for globals or statics in PHP.

@DaggNabbit The difference is more conceptual than internal/functional.

if you called it from a class, it wouldn't have a $this binding (except actually it would)

Not to mention that instance methods are properly scoped.

I can live with this

try (BufferedWriter bufferedWriter = Files.newBufferedWriter(path.resolve("manual.xml"))) {
    xmlOutputter.output(document, bufferedWriter);
} catch (IOException ex) {
    throw new UncheckedIOException(ex);
}

my point is it's not a matter of whether there's a "good" use case or not. Isn't it enough to assume that the people who designed PHP wanted the language to be complete, saw statics in every other language, and implemented it so people didn't whine about there not being statics?

@DaggNabbit As someone who is involved with PHP's internals: No, that's not how features are implemented most of the time.

Here's a nice example:

php.net/manual/en/class.datetimeimmutable.php

11:36 AM

@skiwi: It looks better like:

well then, as someone who's involved with php's internals, you should be in a position to answer the question of why statics are in the language yourself

@DaggNabbit Because someone decided that it should be, and did so without conferring with anyone else.

try (Writer writer = Files.newBufferedWriter(path.resolve("manual.xml"))) {
    xmlOutputter.output(document, writer);
} catch (IOException ex) {
    throw new UncheckedIOException(ex);
}

That doesn't make it good.

See the example I posted above

how is that datetime thing relevant

11:37 AM

Also, skiwi, I see you did that, and also, what if the writer was on a long-lived socket....

@rolfl Coding against interface there?

not sure what you mean

@DaggNabbit It's another piece of crap that someone just decided to have one day, and he did it without asking anyone.

How do you mean on a long-lived socket there?

@rolfl You changed BufferedWriter to Writer

if JDOM was on the server side of a socket, sending XML to the client, you don't want the writer closed.

11:39 AM

Ah, I agree

@MadaraUchiha it does look useless, but an isolated thing like that is not really comparable to a language feature like statics

As always, you are correct @rolfl

Except when using Java 8 :p sometimes

If you give XMLWriter an open writer, then it is the calling code's responsibility to close it

@skiwi Java 8 does not change what is right

@DaggNabbit statics was mindlessly taken from other languages without thinking of the reason of why statics need to be used.

that's exactly what i'm saying

11:40 AM

@rolfl I more meant that you are very experienced (duh) with JDOM2, but not so much with Java 8

although i wouldn't have phrased it quite like that

@DaggNabbit That doesn't mean you should be using it in PHP!

Java8 does not change what's right.

Like I already said, in PHP, there are absolutely no use cases for statics. Any pro it has on other languages is nullified by PHP due to the very nature of PHP applications.

i'm not saying you should be using it, i'm saying it's there for people who don't know any better

11:41 AM

If you need a static method, just use a function!

I'm not saying either that JDOM2 needs to be changed because of java 8 or anything

@DaggNabbit Hence: My ranting about statics and encouraging people to not use it.

I'm ranting because you should not be using statics in PHP, at all.

scope is a wonderful thing, it helps with garbage collection, with modularity and overall quality of the code, why trample it horribly like that with statics and globals?

well, suppose you are porting something from another language to php, and it has statics, because they made sense there. You want the API to be identical to whatever it was in the other language. It had SomeClass::createFromFoo(), so you write SomeClass::createFromFoo(). What's the big deal?

@DaggNabbit Because they mean differently.

In Java, you can scope classes

@DaggNabbit You will have to adjust the API either way, because you will "lose" the data on a new request either way. So either do it right or don't

11:45 AM

So statics are also scoped to whatever scope the class was limited to

@MadaraUchiha well make it J2EE (nevermind, wrong scope)

PHP has no such concept.

In PHP all classes, functions and statics are inherently global

@Vogel612 Note the distinction between scope and namespacing.

@MadaraUchiha note the distinction between scope and scope :(

(I honestly have no idea what J2EE is :D)

@Vogel612 php is not necessarily just a one-shot cgi-style thing. There can be long-running php programs, even if people don't usually do that

11:47 AM

Enterprise Edition

@MadaraUchiha Java EE

@DaggNabbit you still lose all the data when making a new request.

@DaggNabbit There can also be webservers in C++, you don't do that, don't you?

@MadaraUchiha i don't but some people do

in JEE you have Scopes for Backing Beans, that correspond to different lifecycle phases of a website usage.

e.g: @RequestScoped, @ApplicationScoped, @SessionScoped and a few others.

@Vogel612 you are missing the point, i'm saying it doesn't have to be a run-once-per-request-and-die type of setup

@DaggNabbit If you are looking for that kind of application, PHP is probably not the best tool for the job anyway.

11:49 AM

@DaggNabbit you miss the point that it always IS either way. (at least from what I take of the Second Rikudo's comments)

@Vogel612 PHP can be run from the command line

It doesn't have be run in web-sapi context.

Although it usually is

However, for these sort of applications, you probably don't want PHP anyway.

Monking!

And even you do, the use of statics in that is an edge case of an edge case.

is that again one of these:

> another piece of crap that someone just decided to have one day, and he did it without asking anyone.

Monking @Mat'sMug ;)

@MadaraUchiha probably not, but you can see where language designers would like to think of their language as being more generally useful than whatever people normally want to use it for

11:52 AM

You also have something to contribute to our PHP wars?

Does a ++ operator even make sense on a Fraction type?

@DaggNabbit that's sham

Why not?

why not what?

@Mat'sMug Yeah, why not

Please expand on "increment/decrement operators are broken", I intended {1/2}++ to return {2/2}.. like, var oneThird = new Fraction(1,3); oneThird++; - oneThird is now 2/3. — Mat's Mug 7 hours ago

11:53 AM

One problem.,. what's more intuitive::

@Mat'sMug I expect ++ to add a whole one.

Ah

0.5++ = 1.5

3/3 ++ = 4/3 || 3/3 ++ = 6/3

But that's my opinion

11:55 AM

So what I've done is better off in a IncrementNumerator method perhaps
