best libraries for a journalling app (windows only)

hey guys. so i wanted to make a journalling app myself that'll keep me more accountable in the future. sure, i could use a markdown editor like obsidian or vscode's built-in markdown viewer, but i'm a developer and the best part about being a developer is remaking stuff that already exists just because you can aside from the backstory, what would be good libraries for this sort of thing? looking for a relatively gentle learning curve where i can get a grasp of the basics and get started easily. open to all suggestions and i need something to do over these coming weeks. this will probably be only a windows project, as my friend group only uses windows which is who i'll probably distribute this to. lemme know what you think 👍🏽

code builds but hangs while running

code: https://paste.pythondiscord.com/KTVQ when i build it in release, everything works fine. but when i run in release, it just hangs and does nothing, even though all i'm doing is this:

class Program
{
    // ... <- nothing up here is run

    static void DisplayHelp()
    {
        string help = """
        This is a test help screen.

        What do you think?
        """.Trim();

        Console.WriteLine(help);
    }

    static void Main()
    {
        DisplayHelp();
    }
}

class Program
{
    // ... <- nothing up here is run

    static void DisplayHelp()
    {
        string help = """
        This is a test help screen.

        What do you think?
        """.Trim();

        Console.WriteLine(help);
    }

    static void Main()
    {
        DisplayHelp();
    }
}

how do stacks, lists, arrays, etc have a collection expression?

is it part of the compiler or is there a special function or attribute you can give code in order for it to work that way?

"Object reference not set to an instance of an object"

code: https://github.com/axololly/chess/tree/main/Board.cs#L1073 not sure why this is happening. i changed the Board from a class to a struct so it's no longer heap allocated (used in an engine, so these things matter) and now it's raising weird errors like this

✅ this error makes no sense

getting a null reference exception here:

static Evaluation eval = new();

static Evaluation eval = new();

and that traces to this:

mgTable[pc][sq] = mgValue[p] + GetMGTable(p)[sq];

mgTable[pc][sq] = mgValue[p] + GetMGTable(p)[sq];

and THAT traces to this:

static int[][] mgTable = new int[12][];

static int[][] mgTable = new int[12][];

am i dumb or is this just not how you construct an array like that?

✅ how do i publish my .NET project?

so i made this chess thingy (do check it out, i spent a month on it) and I want to publish it online so i can primarily use it in my other projects. how exactly do i go about this? i'm using vscode btw - vs runs like shit and doesn't correct my code properly. command line would be preferred.

✅ impossible error

so i'm using a Stack<Move> for my chess board's move history. it somehow managed to raise an out-of-bounds error with the line being directly correlated to this line:

moveHistory.Push(move); // Index was outside the bounds of the array.

moveHistory.Push(move); // Index was outside the bounds of the array.

i have zero fucking clue what this is caused by. here's the rest of my code: https://mystb.in/4b14af70b18dc60777 (line 225-250)

null check raising errors

i come from python and my first interpretation was that they can work like decorators, but that's clearly not the case. my question is how do i modify class data with an attribute? like how in python you can decorate a class like this:

def change(name, value):
    def wrapper(cls):
        setattr(cls, name, value)
        return cls

    return wrapper

# ...

@change("num", 4)
class MyClass:
    def __init__(self):
        self.num = 10

mc = MyClass()
print(mc.num) # prints 4 and not 10

def change(name, value):
    def wrapper(cls):
        setattr(cls, name, value)
        return cls

    return wrapper

# ...

@change("num", 4)
class MyClass:
    def __init__(self):
        self.num = 10

mc = MyClass()
print(mc.num) # prints 4 and not 10

how would i do this in C#?

✅ how do i override built-in methods?

i come from python where you can override methods in a class to work a certain way. for example, for use in the == operator, you can override a class to modify the behaviour of the __eq__ method which checks if two objects are equal. if i wanted to do an XOR on a class that holds an internal value, how can i override it so it works on the internal value instead of the class itself?

✅ ternary select between static classes

i have two static classes like this

public static class WhitePieces
{
    ...
}
public static class BlackPieces
{
    ...
}

public static class WhitePieces
{
    ...
}
public static class BlackPieces
{
    ...
}

and i'm trying to select between them like this

var pieceClass = sideAttacking == Colour.White ? WhitePieces : BlackPieces;

var pieceClass = sideAttacking == Colour.White ? WhitePieces : BlackPieces;

and i'm getting this error:

'WhitePieces' is a type, which is not valid in the given context

'WhitePieces' is a type, which is not valid in the given context

why is that?
