SAPIEN’s Primal Forms 2009 now has an integrated script editor that you can use as a standalone editor for PowerShell scripts. The app has integrated help, popup command help, a PowerShell browser, a .NET object browser. As you can see in the screen shot I’ve started a very basic PowerShell script.
Once saved, I can run the script and view the results in the output panel. You can open and edit existing scripts as well. If you want a more full featured editing experience with code samples, snippets and more, or if you still need to work in other languages like VBScript, you’ll want PrimalScript 2009. But let’s say you only require an easy to use PowerShell script editor that provides a Windows Form feature, then PrimalForms 2009 is the ticket.
