  • Git bisect and PowerShell

    Inevitably when writing code there will be bugs, it’s just part of being human and writing code and especially true when the code gets complex. So when it occurs we need to track it down and fix it, which can be easy, but we often want to track down where the bug was introduced so we can figure out what caused it (especially for the more difficult to pinpoint bugs). As we’re all using source control this becomes easier with git and it’s extremely powerful bisect tool.

  • Enforcing Code Style using Pester

    As part of an ongoing effort to improve code quality and consistency across the company we decided to apply the same principles to PowerShell code as we would apply to our C# and other code, since code is code no matter what language it is written in or who maintains it. With this in mind a few of us sat down many months ago and figured out what our style should be using the community style guide as a baseline and picking the things we’d like to apply. With these basic guidelines decided it was up to me to enforce these in some way, and Pester as my tool of choice.

  • [Scriptblock] and ConvertTo-Json: a match made in recursive hell

    I’ve been working on JeaDsc off and on for a few months to improve on the original project and make it available in the PowerShell Gallery. The biggest bug it’s currently got is that it doesn’t compare an existing configuration against a new one very well, especially for complex configurations. For a DSC resource this is a huge problem and something I’ve been wanting to fix got a little while. As part of fixing it I came across this wonderful problem with ConvertTo-Json.
