PowerGUI and Modules

With full PowerShell v2, Windows 7, and Windows Server 2008 R2 support in PowerGUI we obviously absolutely had to fully support Modules – and we do.🙂 Modules are first class citizens in PowerGUI 1.9: you can add them, get intellisense and F1 help in script editor, start searching for them when adding admin console elements, set them as PowerPack dependencies and so on.

As a quick 101: modules are a new format of PowerShell libraries introduced in PowerShell version 2. Unlike snapins in v1, modules can be scripted – so you do not have to use Visual Studio and compile them.

To create a simple module, just take a PowerShell script file with a function, e.g.:

function Add-Number {
param ($A, $B)
    $A+$B
}

Then create a folder with a name you want for a module (e.g. MATH) and save the file into that folder as MATH.psm1.

To make this module listed as available, put the module folder (in our example MATH) into one of the $env:psmodulepath folders. Which basically means C:\Windows\system32\WindowsPowerShell\v1.0\Modules\ if you want it to be available to anyone, or your Documents\WindowsPowerShell\Modules if it’s for you only.

Now, if in PowerGUI (admin console or script editor) you click File / PowerShell Libraries, you’ll see it listed as one of the options:

PowerShell-Libraries

As you can see, other modules (BitsTransfer and PSDiagnostics) are also available, as well as v1-style snapins.

You can also use Add Module button, if you want to add a module which you have outside of the default module folders.

Anyways, once you select MATH and click OK, the module becomes available for you. E.g. you get intellisense and F1 help for the module members:

Module-Intellisense

For more information of creating modules of your own, see this MSDN page.

Happy PowerShell v2 scripting!😉
