Procedural Program Flow

BernieTheBernie

As you know from his previous posts, Bernie's team terribly struggles with Object-Oriented Programming. Well, they received their Master degrees around 1990 when OOP just had crept into main stream (C++ was developed in 1979, and so it might have been to novel for learning it). So at least, they ought to know the older procedural style. Ehm, ...

Bernie found a batch file which calls one of their programs with a parameter -k. Now he was curious to find out where that was handled and what it meant. After all, anyone can immediately see what -k means. With a text search through all the source code, he found it:

public MainView()
{
    string[] args = Environment.GetCommandLineArgs();
    bool noBorder = false;
    foreach (string arg in args)
    {
        if (arg == "-k")
        {
            noBorder = true;
        }
    }
    if (noBorder)
    {
        WindowStyle = WindowStyle.None;
    }
    InitializeComponent();
}

Of course, it is not handled in static Main or in OnStartup - that's for whimps. Even with C#, command line arguments are global, and you can read them from anywhere by calling string[] args = Environment.GetCommandLineArgs();. So they do in the constructor of the main window of a WPF application.

Next, set a boolean variable to flase, iterate over all arguments, and if such an argument exactly is -k, set that boolean to true. Afterwards, check the boolean and set the WindowStyle of that window accordingly. And what about -K (uppercase K)? Bernie's colleagues won't care about such users.

You can shorten the code (and correct it at the same time) to

if (args.Contains("-k", StringComparer.OrdinalIgnoreCase))
{
    WindowStyle = WindowStyle.None;
}

At least, Bernie learned the meaning of -k.

flase

BernieTheBernie

@pie_flavor You are the frist to detect that.

Kian

But what if -K is used elsewhere for selecting bananas out of a list of fruits? You'll be setting the window style when all they wanted was bananas! Or more seriously, what if someone sets many flags at once, such as -rk?

Well, I saw it as well, but my activity response rate is low so just saw it now.

@cvi are you saying @pie_flavour can't spell his own name?

@Jaloopa No, it's just Brit-proof.

What if someone sets flags using forward slash: /k ?

I expect arguments that start with a "-" to be case sensitive. If it starts with a "/" I expect it to be case insensitive.

@Kian You could be right. After all, when they create such a mess, they could also add some Unix flavour to a Windows application.

Gąska

@BernieTheBernie it's already using dashes instead of slashes. Why not go all the way then?

boomzilla

BernieTheBernie

@Gąska Because they prefer a mess. Do not add some kind of unnecessary order to our applications.

BernieTheBernie

@boomzilla Those numbers in the edges, what do they mean? Is it the line number for GOTO?

boomzilla

@BernieTheBernie probably.

He obviously comes from the Unix-style command line args! Case Matters!

-K should do the opposite of -k if both are supported.

@PleegWat I just realized many modern linux utilities also have more descriptive long options, whose names would likely be --borderless and --no-borderless or slimilar.

@boomzilla but it's still appropriate. Shell scripts are some of the deepest fucking magic I've seen in my life.

I did that until relatively recently because 99.9% of all commands I used listed it with / in help, and I didn't even know - is even an option on Windows

Careful. I believe Windows system programs do understand both. CMD commands, however, accept only / (with /- meaning "not to"). And PowerShell and most cross-platform programs accept only -.
