Visual Studio Code, Markdown, and Snippets

Robert Cain takes us through Markdown and snippets in Visual Studio Code:

Seriously though, I do find this documentation language very useful, and easy to use. With just a few commands I can produce a nicely formatted document that can be displayed in my code editor, as well as on platforms like GitHub. I’ve even begun authoring these blog posts in Markdown.

A big reason for me is the ability to integrate it into my projects. VSCode, as well as the full blow Visual Studio, support Markdown (with of course the proper extensions installed). When I create a new PowerShell project in VSCode, I can store the projects documentation in Markdown format right alongside the PowerShell code.

By the way, two VS Code extensions I can highly recommend for their Markdown support are Markdown All in One and markdownlint.

15 Short Code Snippets

Chad Baldwin goes the extra mile:

I’m excited that this will be my first time participating in a T-SQL Tuesday topic!

Most of my time is spent writing T-SQL, PowerShell and working in the PowerShell terminal, so that’s how I’ll split the post up.

I had to cut it short otherwise this post would be a mile long. If you’re interested in seeing more quick tricks, SQL Prompt snippets, etc, please leave a comment and let me know and I can do a Part 2 in the future.

Repurposing Helpful Scripts

Deepthi Goguri re-shares some helpful scripts:

For the past couple of years as a DBA, I migrated several databases and used many handy scripts that helped me made my work easier. These scripts may be simple but if you have a migration project involving several SQL Servers with some hundreds of databases, test and production database migrations becomes tedious. I would like to share some of then here which you might already known them very well.

Using the Power BI REST API for DAX Queries

Gilbert Quevauvilliers writes some Powershell:

In this blog post I am going to show you how to use PowerShell to run a DAX query from my dataset, and then store the results in a CSV file.

I will also include the PowerShell code!

I really liked the awesome blog post by Kay on the Power BI Team which you can find here: Announcing the public preview of Power BI REST API support for DAX Queries

Read on to see what prep work you need to do, as well as the scripts needed to pull this off.

Wackiness with TrimEnd in Powershell

Shane O’Neill digs into TrimEnd:

A couple of days ago, I was running some unit tests across a piece of PowerShell code for work and a test was failing where I didn’t expect it to.

After realising that the issue was with the workings of TrimEnd and my thoughts on how TrimEnd works (versus how it actually works), I wondered if it was just me being a bit stupid.

So I put a poll up on Twitter, and I’m not alone! 60% of the people answering the poll had the wrong idea as well.

The way that works is…not what I would have expected.

Write-Debug in Powershell

Robert Cain goes from verbose to debug mode:

In my previous post, Fun With PowerShell Write-Verbose, I introduced the use of the built in -Verbose switch. In this post we’ll dive into its counterpart, the -Debug switch and its companion Write-Debug cmdlet.

In covering Write-Verbose, I mentioned verbose messages are typically targeted at the average user. The -Debug messages are meant to target the developer. These messages are meant to assist the PowerShell developer in trouble shooting and debugging their code.

Get-FileAgeGroup

Jeffrey Hicks builds a useful function:

If there’s one task I’ve never stopped doing, it is finding files. I am constantly creating new ways to organize files and display them in a meaningful format. Naturally, PowerShell is a great tool for this task. Get-ChildItem is obviously the proper starting point. The cmdlet works fine in getting only files from a folder and I can do basic early filtering by name and extension with wildcards. But my latest task was organizing files by date, and because of the way Get-ChildItem works under-the-hood, I’m going to need to resort to late filtering with Where-Object. There’s nothing wrong with that. But if this is a task I’m likely to repeat, then a PowerShell function is on the drawing board. My goal is to create a function that will display files grouped into aging buckets such as 1-week or 6-months. Even though I’m primarily concerned with age based on the last write time, I (or you) might have a need to base aging on the creation time. Let’s code.
