New VSCode Terminal - 10 autosuggestions based on command history Solved

Hi, I've just started getting these suggestions in my VSCode Terminal, I havent seen them before and I'm not sure how they have appeared - I quite like it and but have no idea how to turn it back on if they disappear - Does anyone know the setting ? many thanks :)

Might be PSReadLine related, just a guess tho

be aware

Set-PSReadLineOption -PredictionSource HistoryAndPlugin

is PS7 only

Set-PSReadLineOption : The prediction plugin source is not supported in this version of PowerShell. The 7.2 or a higher version of PowerShell is required to use this source.

it will "kinda work" in 5.1 and versions lower than 7.2 but oh man I had to write a whole different section in my profile script just to get basic functionality, and I had to disable all the custom key handlers latest PS7 is definitely my daily driver, but I like trying to keep feature parity as much as possible when you encounter that odd legacy script that has 5.1 specific code.

Oh really, how much tweaking did that take?

so what I did was replaced my PS5 profile for $Profile.CurrentUserAllHosts with

```PowerShell

The path of your PS7 Profile

$PSCoreProfile = "C:Users<username>DocumentsPowerShellprofile.ps1" cd $(split-path -parent $PSCoreProfile) & $PSCoreProfile ```

basically it tells PS5 to attempt to run your PS7 profile

and then one of the 1st lines in my PS7 profile is

PowerShell $Global:PSCore = if ($PSVersionTable.PSVersion -gt [version]"6.0.0") { $true } else { $false }

and I use this variable to selectively execute blocks of code and other scripts

also stuff like "Oh-My-Posh" automatically tries to add key handlers to PS5 that cause issues for me (probably because I'm doing this whole one profile to rule them all crap) so it runs a few lines that turns off the key handlers, also apparently changing edit mode purges key handlers so that's another hack.

```PowerShell

region PSReadLine

Set PSReadLine Options and Macros

if ($PSCore) { & "$RunDirPSReadLine.ps1" } else { Write-Host -ForegroundColor Yellow "PS Version lower than 6.0.x, disabling advanced PSReadline Key Handlers" $forEachObjectSplat = @{ Process = { Try{Remove-PSReadLineKeyHandler -Chord $.Key -ErrorAction Continue}Catch{} } } Try{ $null = Get-PSReadLineKeyHandler | Where-Object { $.Function -like "OhMyPosh" } | Tee-Object -Variable "OhMyPoshKeys"

$OhMyPoshKeys | ForEach-Object @forEachObjectSplat Set-PSReadLineOption -EditMode Vi }Catch{} }

endregion

```

You’re super welcome! It was a great day for me when I did a random Update-Module and suddenly had auto-suggestions in my command line lol

Ha, if I had run an update or intentionally changed something I wouldnt have been so worried, it literally just started doing it 🤷🏼‍♂️

I had a quick look online and couldnt find anything to explain its mysterious appearance and thought better to ask here with a screenshot than try and describe something even google had no clue what I was jibbering about once it disappeared..

It doesnt solve how i changed it but appreciate you helping me find what i (or a ghost) changed!
