PSReadLine history doesn't load

I tried to use psreadline today. There is something i don't understand is the history command.

When I run

Set-PSReadLineOption -PredictionSource

The history suggestions start showing up.

I close the terminal ps, open it again, no history suggestions there until i run the command again.

What do I miss?

Solution

  • If this is the only command you are using...

    Set-PSReadLineOption -PredictionSource

    .. then that is not complete.

    As per the Powershell docs here: MS Docs | PSReadLine

    -PredictionSource
Specifies the source for PSReadLine to get predictive suggestions.

Valid values are:

None: disable the predictive suggestion feature
History: get predictive suggestions from history only

    So you have to tell it what you want:

    Set-PSReadLineOption -PredictionSource History

    or

    Set-PSReadLineOption -PredictionSource None

    The latter is the default if you don't tell it. Just put the former in all your console profiles.

    Get-PSReadLineOption
<#
EditMode                               : Windows
AddToHistoryHandler                    : System.Func`2[System.String,System.Object]
HistoryNoDuplicates                    : True
HistorySavePath                        : C:\Users\WDAGUtilityAccount\AppData\Roaming\Microsoft\Windows\PowerShell\PSReadLine\ConsoleHost_history.txt
...
PredictionSource                       : None
...
