Power BI / Power Query

Things to note

  • options is an record, when used this way it’s similar to Python’s kwargs
  • Merging two records with update the existing fields, adding new fields, if they do not yet exist
  • (in PowerQuery) the order of steps don’t change the final result (order of execution is the same) That’s why defaults after config works
  • Sometimes readability improves when placing large “blocks” like values_list out of order so the logic is on top
  • I replaced values *before* converting them to text so you have more control (before coercion )
Text.JoinSpecialValues_impl = (source as list, optional options as nullable record) as text =>
    let
            config = Record.Combine({defaults, options ?? []}),
            defaults = [
                Separator = "|",
                UseSpecialSymbols = true
            ],
            text_list = List.Transform( values_list, Text.From),
            joined_string =  Text.Combine( text_list, config[Separator] ),
            values_list  = if not config[UseSpecialSymbols] then source else
                List.ReplaceMatchingItems( source,
                    {
                        // replace true null, and true empty strings (vs whitespace)
                        { null, "␀"},
                        { "#(cr,lf)", "#(240d)␀" }, // is #(2424)" }
                        { "#(lf)", "␀" }, // is #(2424)" }

Using Inline Images and SVG in a Power BI Table

With the column set to Image Url, you’re able to

  • use an external image like https://www.fakeurl.com/image.png
  • or output a svg image programmatically, by placing logic in a measure
  • or embedded a raw a .png image into the model/report itself
    • First encode the image Base64
    • Save that text in a table
    • Finally create a measure that prefixes the text with
[Inline Png ] := 
      "data:image/png;base64, " & SelectedValue( [ColumnWithText] )

Random Power Query

Power Query Sugar for selecting distinct filters. If the condition is not true, then it throws an error. Name = "Orders" works because it results in a distinct value from the column Name It’s valid even though the final query is many records. It’s the “distinctness” of the filter that is required to be true

Source{ [Name = "Orders", Signature = "table"] }

PowerShell Quick Tips

Creating a Discord Webhook in a few lines of PowerShell

Discord Web Hooks are easier than you’d think. It uses a regular `HTTP` web request .

Step1: Creating your webhook url

Go to: Server Settings -> Integrations -> View Webhooks
Then click create webhook.

Choose a name, the channel, then copy webhook url

Step2: Invoke-RestMethod

$webhookUri = 'https://discord.com/api/YourWebhookUrlHere'

$Body = @{
  'username' = 'Nomad'
  'content' = 'https://memory-alpha.fandom.com/wiki/Nomad'
}
Invoke-RestMethod -Uri $webhookUri -Method 'post' -Body $Body

Success!

Docs

There are optional webhook arguments to customize the output: https://discord.com/developers/docs/resources/webhook#execute-webhook

Comparison with curl

I tried making curl easier to read by splitting content, and pipe so that you don’t have to manually escape Json

$Json = @{ 'username' = 'Nomad'; 'content' = 'https://memory-alpha.fandom.com/wiki/Nomad' } | ConvertTo-Json -Compress

$Json | curl -X POST -H 'Content-Type: application/json' -d '@-' $webhookUri

Command Line PowerShell Quick Tips References And Cheat Sheets

Easy way to cache results on the Command Line | Power Shell Tip

Sometimes you’ll need to run a command with the same input with different logic.
This can be a hassle using a slow command like Get-ADUser or Get-ChildItem on a lot of files like ~ (Home) with -Depth / -Recurse

ls ~ -Depth 4 | Format-Table Name

PowerShell 7.0+

Powershell 7 added the Ternary Operator, and several operators for handling $null values.

All of these examples will only run Get-ChildItem the first time. Any future calls are cached.

Null-Coalesce ??= Assignment Operator

This is my favorite on the Command line. The RHS (Right Hand Side) skips evaluation if the left side is not $null

$AllFiles ??= ls ~ -Depth 4

Using the Null-Coalesce ?? Operator

$AllFiles = $AllFiles ?? ( ls ~ -Depth 4  )

Ternary Operator ? whenTrue : WhenFalse

$allFiles = $allFiles ? $allFiles : ( ls ~ -Depth 4 )

Windows PowerShell and Powershell < 7

Windows Powershell can achieve the same effect with an if statement

if(! $AllFiles) { $AllFiles = ls ~ -Depth 4 }

PowerShell : Prefixing lines with the Pipe operator |

There’s a lot of ways to use line continuations in Windows Powershell without backticks . Powershell added a new one, the | pipe operator. It’s cleaner to read, and makes it easier to insert, delete, or toggle comments on the console.

Now you can write:

# Powershell
ls | sort Length
| Select -First 10
| ft Name, Length

Instead of piping on line endings

# Windows Powershell
ls | sort Length |
Select -First 10 |
ft Name, Length

# or
ls | sort Length | Select -First 10 | ft Name, Length
