MarkdownPS is a PowerShell module that wraps the markdown syntax into PowerShell cmdlets.

Initially I ran into the PSMarkdown for which ishu3101 had developed a cmdlet that renders a table in markdown syntax. This was very useful and I decided that I needed more functionality provided by cmdlets to render other aspects of markdown. After discussing with ishu3101 I pushed a head and created a module of my own. The New-MDTable cmdlet’s code is inspired by the ConvertTo-Markdown by ishu3101 but I enhanced it with column alignment.

This is my first open source projects in GitHub, so I took the opportunity to educate myself a bit about it. The MarkdownPS repository is integrated with visual studio services and I also use Pester to unit test each cmdlet. Overall, it was a good experience while picking up PowerShell knowledge along. Integrating Pester from Visual Studio Services is a bit tricky because VSS runs on PowerShell 4 and the Pester is available with PowerShell v5. The solution is available in code.
