disable (and scrub existing) history permanently

TL;DR: how to disable history?

hi, I'm making a move from linux to windows development and I'm using pwsh with oh-my-posh and my prompt looks absolutely fabulous!

just one thing that irks me is the history that tries to give me suggestions when I'm typing.

at first I thought it was something to do with oh-my-posh itself, but after searching a bit it seems the functionality comes from PSReadLine.

I just need history and the attempt to give me suggestions from it gone, but I don't want to disable auto completing, such as pressing tab after Get- to get suggestions there. does that make sense?

welp, I should have done a bit more research! found the answer a bit after posting this, so I'll just share anyway:

Remove-Item (Get-PSReadlineOption).HistorySavePath to delete history
Set-PSReadLineOption -AddToHistoryHandler { return $false } in your profile to disable

real solution is to just disable predictions. duh.
Set-PSReadLineOption -PredictionSource None in the profile. k, I'm done editing now.

cheers!
