Code Layout and Formatting: Indentation · PowerShell Practice and Style

Posted by jpluimers on 2021/09/22

Since I switch a lot between languages, I tend to forget what indentation, spacing and termination to use.

So from the Indentation/Length/Spacing/Termination sections in [WayBack] Code Layout and Formatting · PowerShell Practice and Style:

PowerShell OS Support Matrix – mohitgoyal.co

Posted by jpluimers on 2021/09/08

By now, probably newer versions have come out, but this should give a rough indication of the 2019 state of [WayBack] PowerShell OS Support Matrix – mohitgoyal.co:

For 5.1 and lower, you can find the prerequisites in [WayBack] Windows PowerShell System Requirements – PowerShell | Microsoft Docs.

“A parameter cannot be found that matches parameter name ‘PassThru'” – likely your powershell version is too old

Posted by jpluimers on 2021/09/07

If you get [WayBack] “A parameter cannot be found that matches parameter name ‘PassThru'” as PowerShell error, then likely the PowerShell version is too old to support -PassThru, which likely means you have are running pre-Windows 10 version.

PowerShell 3 (introduced in 2012) added the -PassThru parameter that allowed to chain multiple commands from one list pipe.

Another reason for the error might be that the command you use does not support the -PassThru parameter.

To check which commandlets support -PassThru, use the below command (the output is from a Windows 8.1 machine running PowerShell 4.0).

Posted by jpluimers on 2021/08/24

The Flux architecture is often used in ReactJS, but there are also implementations outside that realm.

So here are some links for my archive:

Attacking Technical Debt – ardalis

Posted by jpluimers on 2021/08/12

Interesting approach in [WayBack] Attacking Technical Debt – ardalis.

The tech stuff is C# and .NET based, but the general approach can be applied in a universal way.

via: [WayBack] Jim Holmes on Twitter “Great post by @ardalis on attacking Technical Debt. … You should also read my series on creating a Technical Debt Payment Plan, starting here: …”

So also read

Naming of naming styles should reflect their casing · Issue #35243 · dotnet/roslyn · GitHub

Posted by jpluimers on 2021/08/04

If this is still open, please vote for it: [WayBack] Naming of naming styles should reflect their casing · Issue #35243 · dotnet/roslyn · GitHub

Having the drop down of naming styles reflect the actual output in one way or the other will make it way easier to select the correct one.

Besides that, a few new naming styles are suggested in this issue, like snake_case which is great for translating APIs that are already in that form.

Methods on enums by using extension methods: Unity sample MonoBehaviour explaining how to associate simple strings with enums.

Posted by jpluimers on 2021/07/29

Reminder to self (as I keep forgetting how versatile extension methods can be):

[WayBack] Mark Pintar sur Twitter : “The nice thing about extension methods is one can add it to most types. Even works of int, float and other primitive types… “

An interesting way of allowing methods on enumerated types is by using extension methods: [WayBack] Unity sample MonoBehaviour explaining how to associate simple strings with enums. · GitHub.

A more elaborate example from [WayBack] NoraGrace-Chess/Position.cs at master · ericoldre/NoraGrace-Chess · GitHub is below the fold.

using System;
using System.ComponentModel;
using UnityEngine;

public class EnumDescription : MonoBehaviour
{
    public enum PlayerState
    {
        Unknown,
        [Description("Alive and kicking")]
        Alive,
        [Description("Dead as a duck")]
        Dead
    }

    // Start is called before the first frame update
    void Start()
    {
        var state = PlayerState.Dead;
        Debug.Log("Player is " + state.GetDescription());
    }
}

public static class EnumExtensions
{
    public static string GetDescription(this Enum value)
    {
        var type = value.GetType();
        var name = Enum.GetName(type, value);
        if (name != null)
        {
            var field = type.GetField(name);
            if (field != null)
            {
                if (Attribute.GetCustomAttribute(field,
                  typeof(DescriptionAttribute)) is DescriptionAttribute attr)
                    return attr.Description;
            }

c# – Algorithm to check whether a certain hour falls into a given time period – Stack Overflow

Posted by jpluimers on 2021/07/15

For my link archive: [WayBack] c# – Algorithm to check whether a certain hour falls into a given time period – Stack Overflow answered by [WayBack] kennytm:

Assume you only have the time and not the date.

if end_time >= start_time:
    return start_time <= current_time <= end_time
else:
    return start_time <= current_time or current_time <= end_time

I totally agree with this comment:

This is brilliant! Thanks a lot. – Martin Dimitrov [WayBack]

I love it when algorithms are simple and elegant.

It reminded me of another scheduling related algorithm: [WayBack] Activity Selection Problem | Greedy Algo-1 – GeeksforGeeks
