Powershell autocomplete with PSReadLine

July 30, 2021

As of powershell 6 you have a module called PSReadLine installed by default. This module changes the editing experience of powershell and is customizable. One thing that I really like is to have auto completion for historical commands. In this post I will show you how I setup PSReadLine in my profile.

Start by installing PSReadLine.

Get-Module -ListAvailable PSReadLine Install-Module PSReadLine

Then open up profile code $PROFILE

#Imports PSReadLine Import-Module PSReadLine #Tab - Gives a menu of suggestions Set-PSReadLineKeyHandler -Key Tab -Function MenuComplete #UpArrow will show the most recent command Set-PSReadLineKeyHandler -Key UpArrow -Function HistorySearchBackward #DownArrow will show the least recent command Set-PSReadLineKeyHandler -Key DownArrow -Function HistorySearchForward #During auto completion, pressing arrow key up or down will move the cursor to the end of the completion Set-PSReadLineOption -HistorySearchCursorMovesToEnd #Shows tooltip during completion Set-PSReadLineOption -ShowToolTips #Gives completions/suggestions from historical commands Set-PSReadLineOption -PredictionSource History
