Change window title on Powershell?

[ransagy]

As per the documentation, one needs to define the logic of setting the window title before launching Starship. However, The documentation only mentions the *nix family of shells.

In Powershell the way to do this AFAIK is the following:

function SetWindowTitle {
    $host.UI.RawUI.WindowTitle = $PWD  # always set to the path, as an example.
}

However, I'm not too sure about the equivelant of the precmd commands in this case. Is this somethign Starship needs to do/support or am i missing something in my $PROFILE file to be set before Starship launches?

I've been thinking about this and src/init/starship.ps1 probably needs to be modified to change the window title. No big a deal IMHO.
However, what value do we want the window title to be? the current working directory? the complete prompt?

[davidkna]

Shouldn't we just add documentation for that like with the nix shells?
Yes supporting some kind of starship_pre_cmd thing sounds good.

[ransagy]

I'd start with the current working directory; I believe that's what Powershell does by default. Obviously other scripts/apps can change the title as well but that shouldn't concern us.

It would be a nice bonus to make it configurable as i can definitely imagine some people wanting it to mimic the prompt itself. (which in turn is exactly what would make it configurable to begin with?)

[davidkna]

I just tested in plain powershell and no window title gets set.

Powershell 7 (Core) seems to do this for me; it could be the posh-git module i used before Starship, as well.

[davidkna]

Using @(starship prompt)[1] for the window title could work but you'd have to somehow get rid of the ansi color escapes (a second starship config with lots of style strings maybe?).

In powershell you can use for now

function SetWindowTitle {
    $host.UI.RawUI.WindowTitle = $PWD  # always set to the path, as an example.
}

# Starship must come first
starship init powershell | iex

$oldPrompt = $function:prompt
function prompt {
	$null = SetWindowTitle 
	& $oldPrompt
}

(stolen from zoxide)

Also akin to zoxide for $PWD chnages only this will work:

$ExecutionContext.InvokeCommand.LocationChangedAction = {
	$null = SetWindowTitle 
}

[ransagy]

Seems to work for me without the last part. Maybe i misunderstood you though. Just adding the first part to my $PROFILE seems to work well.

[davidkna]

They are differnt methods to achive the same thing.
$ExecutionContext.InvokeCommand.LocationChangedAction triggers on every directory change and prompt on every prompt draw.

[ransagy]

Oh, I misread the last part, indeed. Either way, Thank you, works splendidly for now :]
