Setup PowerShell Autocomplete

Enable Linux-style shell autocompletion in PowerShell using the PSReadLine module.

Installation

Install-Module PSReadLine

Configuration

Edit your PowerShell profile:

notepad $PROFILE

Add the following code:

# Check if PSReadLine module is available, if not, install it
if (-not (Get-Module -ListAvailable -Name PSReadLine)) {
    Install-Module -Name PSReadLine -Force -Scope CurrentUser
}

# Check if PSReadLine is loaded, if not, import it
if (-not (Get-Module -Name PSReadLine)) {
    Import-Module PSReadLine
}

# Shows navigable menu of all options when hitting Tab
Set-PSReadLineKeyHandler -Key Tab -Function MenuComplete

# Autocomplete for Arrow keys
Set-PSReadLineOption -HistorySearchCursorMovesToEnd
Set-PSReadLineKeyHandler -Key UpArrow -Function HistorySearchBackward
Set-PSReadLineKeyHandler -Key DownArrow -Function HistorySearchForward

Set-PSReadLineOption -ShowToolTips
Set-PSReadLineOption -PredictionSource History

This makes your terminal start slightly slower, but it’s worth it.
