If this is working code, the it is off topic here and should be in the Code Review Stack Exchange, where people critique and make suggestions for improving otherwise working code. — MatthewMartin 31 secs ago

I think we're out of Tic Tac Toe titles now. This question must've gotten very hot quickly, too.

Q: Connect 4 (glorified tic-tac-toe) implementation

I'm posting here my implementation of the game Connect 4. It's obviously a pretty trivial game and code but I'm primarily interested in any advice concerning improvements to the code structure: types, dependencies and coupling, concerns, etc. I'm interested in attacking more complicated games bu...

This answer made it back up to -2 so it's not faded anymore. :(

> Get into the habit of placing the bodies of if, for, else, etc in curly braces, unless you have a VERY specific and convincing (to someone else) justification not to. Such things are strongly recommended in most style guides for a good reason. And remember that indentation does not change the meaning of code in any way.

I have no problem with this statement

@Mat'sMug You still got flags to spare on SO?

> However, although it answers the question as asked, this is NOT a technique I would ever recommend. There are so many ways that such hacks could confuse programmers - including yourself in future - that it is simply not worth it. Code that is easy to misunderstand is easy to get wrong.

At the end of the day, drive-by SO users are looking for snippets to copy-pasta, and that answer provided a bad-practice copy-pasta.

@BernardMeurer yup, we know.... But our goal is to have it run jQuery natively.

Did I just miss a PPCG-fest?

^^

Cᴏɴᴏʀ O'Bʀɪᴇɴ

Announcement: jQuery is bad for most conventional tasks. Do not use it unless you must.

@EasterlyIrk Make JQuery run assembly and I'll support it

@CᴏɴᴏʀO'Bʀɪᴇɴ making an OS isn't a conventional task, is it?

@Mat'sMug True. 'twas just a simple announcement ^_^

@BernardMeurer you can just render the GUI with HTML and JS

"It looks like you're trying to make an OS... you should totally drop that and use jQuery instead."

also webassembly

If you're trying to make an OS... why?

8:50 PM

@AlexA. you should totally drop operating systems and use jquery

If you're trying to develop your own programming language... why?

@nhgrif ^^

@Quill GUI? Heretic

@nhgrif I agree with the comments, but the answer is answering the question. I downvoted the question.

Cᴏɴᴏʀ O'Bʀɪᴇɴ

@nhgrif Developing a programming language isn't hard. Developing a useful programming language is harder.

8:52 PM

If you're trying to write your own code instead of using code already written and test and easily imported in a library... why?

@BernardMeurer Terminal is best.

I live on keyboard shortcuts that require assistance of your coworkers to get done

If you're not writing automated tests... why?

You guys have heard of Test Driven Development, right?

Have you heard of Bug Driven Testing?

Testing is for weak people, the bug's only exist when they are experienced. Every bug is a schrödinger cat

@nhgrif is that when you encounter a bug, write a test to cover it, fix the bug, and walk away happy with yet another green test so that the bug can't show up again without failing the CI build?

8:54 PM

So if you don't search for them they don't really exist

@Mat'sMug Sort of ish, yes. But my next blog post takes this a level farther...

@BernardMeurer or, if your code doesn't have users yet. users will find the bugs, 100% guaranteed.

I started a conversation with our CTO yesterday... this week, I'm going to be coming up with a plan for a lot of this idea of Bug Driven Testing.

@Mat'sMug It's legacy code by then

Tests confirm whether or not your code works. Bugs confirm whether or not your tests work.

If I can modify your code base an insert a bug, and then run your test suite... if you don't have at least one failing test, your tests aren't good enough, are they?

So for example... if you write func fizzBuzzify(value: Int) -> String and it does what we expect it to do... and your "tests" look like this...

func testFizzBuzzify() {
    XCTAssertEqual("Fizz", fizzBuzzify(3))
}

I could modify that function to look like this:

func fizzBuzzify(value: Int) -> String {
    return "Fizz"
}

your test would still pass

but the function obviously would not be performing correctly... so even though you get 100% code coverage... your tests aren't good enough.

8:59 PM

gist.github.com/bemeurer/8a768991e5636b330472

Best development methodology ever

Code coverage percentage is a useful statistic, but it only shows you which lines of code were executed during an automated test. Code coverage doesn't show you whether sensible asserts are being made.

@BernardMeurer by M.Feathers' definition legacy code is code without tests.

By my definition, it's code without tests and documentation.

@Mat'sMug That's pretty accurate

or

9:03 PM

Legacy code is XGH code

some code is exempt from documentation if it is self-documenting.

self-documenting code is the ideal.

No. Legacy code is UGH code.

@Mat'sMug Ugly Go Horse?

@nhgrif well-named tests are documentation

@BernardMeurer no. Just "ugh".

I disagree.

Well-named tests are self-documented tests.

9:06 PM

> This is a very complex Axiom, it suggests that a project using XGH is immersed in chaos. Do not try to set order to XGH (See Axiom 16), it's useless and you'll be wasting precious time. This will cause the project to sink even faster (See Axiom 8). Do not try to manage XGH, it is self sufficient (See Axiomm 11), just like chaos.

If I pull a library into my code base, I shouldn't have to pull the tests in too just to get the documentation.

Legacy code is that

They tell you what the thing is supposed to be doing and how

@nhgrif right

You guys scared away the PPCG people with all this talk about testing and code quality.

What's PPCG?

Private Party Communist Guerrilla?

@BernardMeurer Programming Puzzles and Code Golf.

Tests are a form of documentation, but not, by themselves, acceptable documentation.

Didn't even see that message, my bad

lol

So what's after blog posts for @nhgrif? Should he do talks next?

@nhgrif Interview me

9:09 PM

Now that I've been writing Swift... I wonder how in the world people writing languages without optionals/nullables survive.

Depends of the context. Take Rubberduck's resolver code; documenting it would be replicating 100% of the VBA language's scoping rules, and that would be a waste of time.. and a boring read.

possible answer invalidation by wnerb on question by wnerb: codereview.stackexchange.com/posts/123304/revisions

Well, @Mat'sMug, I have a different level of criteria for documentation in end-use code versus reusable library code.

If you're talking about a framework, then yeah I definitely agree

library, framework, whatever

9:11 PM

Framework != library

Anything that's reusable code.

Including things that are reused throughout your project and not extracted out to a library.

But again, remember, in some cases, if the class & method names are good enough, they're self-documenting.

papa-bless-those-who-document

goes to github to write documentation

For example...

// Does the thing
func doTheThing()

@BernardMeurer Posted that to PPCG. They should have a good laugh

9:13 PM

That's not really helpful, is it?

@Sherlock9 Gimme PPCG

@PinCrash Testing is mandatory, posting explanations is optional, quality is dubious, at best

But...

in The Whiteboard, 6 mins ago, by iksemyonov

what are the rules for codereview.se.com? namely, if i have 2 related code pieces that can function independently but make little sense to show them separately, can i post both in one question?

you guys might be interested in that :)

typical GhostDoc lazybones documentation

9:14 PM

// Does the thing.  If circumstance X, Y, or Z arises, the thing is actually not done.  This method fails silently.
func doTheThing()

That's important to be documented.

Of course, the comment format should be in whatever appropriate format that assures it fills out tooltips in appropriate IDEs and can be generated into HTML or PDF documentation packet using whatever appropriate tools.

There's a great Xcode plugin called VVDocumenter that automatically formats my comments with AppleDoc comment style so that I get the IDE pop-ups and can generate an HTML page for my project fully documented. ;)

Haha...

Flagged as UWYA, seemed appropriate.

Well, he said he included the code.

I call bullshit, but that's what he says.

It's simply very, very, very broken.

I think { } is valid JavaScript

@PinCrash It is. It creates an empty object.

An anonymous empty object I assume?

Don't mind me lurking. One thing that I am finding this part of SE really helpful with is the availability of code to look over and (gradually) learn.

Greetings everyone

@Mat'sMug to continue the discussion of Jedi Swift...

if let date1 = getValueForKeyFromPersistentStorrage("latestepisode"){
        let Date1 = date1 as! NSDate

Line 2 is called a force cast.

love it haha

Line 1 is optional binding, the right way to unwrap an optional

The correct way to write this looks like this:

9:53 PM

s/write/right/?

no...?

think about it.

"the write way" is some kind of meme then?

oh

I was looking at a different line

if let latestEpisodeDate = getValueForKeyFromPersistentStorrageThisIsATerribleMethodName("latestEpisodeMagicStringShouldBeAConstant") as? NSDate {

Note the as? NSDate

if the method returns anything but an NSDate, the optional binding fails, and we enter the else branch.

makes sense
