A V3 PowerShell module to improve tab expansion and Intellisense

TabExpansion++

V3 of PowerShell has excellent support for tab expansion and Intellisense, but it is missing some useful features. This module addresses some of those shortcomings.

TabExpansion++ adds support for the following:

• Easily add custom argument completion.
• Complete attribute argument names, e.g. [CmdletBinding(Def -or- [Parameter(
• Exclude hidden files from results.
• Easily set options like 'IgnoreHiddenShares'.

In addition to making it simple to add custom argument completion, TabExpansion++ provides many useful custom argument completers that can also serve as good examples of how to add your own.

Say you wanted to support completing the argument to -Verb parameter of Get-Command, e.g.:

Get-Command -Verb <TAB>

You could do so by adding the following function to your profile:

function VerbCompletion
{
    [ArgumentCompleter(Parameter = 'Verb', Command = 'Get-Command')]
    param($commandName, $parameterName, $wordToComplete, $commandAst, $fakeBoundParameter)

    Get-Verb "$wordToComplete*" |
        ForEach-Object {
            New-CompletionResult $_.Verb ("Group: " + $_.Group)
        }   
}

Usage

Assuming you've installed the module somewhere in your module path, just import the module in your profile, e.g.:

Import-Module TabExpansion++
