Add command-line flag to open the given file/folder in a new window instead of tab

[sindresorhus]

On macOS, I can run this in the Terminal app:

open -a 'Ghostty' .

To open the current folder in a new Ghostty tab.

However, it would be useful to also be able to force it to open in a new window.

I think it could be a new command-line flag, so this would work:

open -a 'Ghostty' . --args --new-window

It obviously makes no sense to open from Terminal to Ghostty. That's just an example. My specific use-case is to support opening new Ghostty windows in my Supercharge app. Users have requested this.

#2353 will let you do this the only other solution would be to be able to start a new instance of ghostty by adding -n to your open command

I think this is the right answer for this use case.

This is not a solution. You would get multiple Dock icons and it could easily corrupt config as most apps don't expect there to be multiple instances of the app running at the same time.

I don't see why this should be blocked by a full-blown scripting API. This is just about passing a single command-line flag directly to the app.

It isn’t fundamentally, I just think that’s the best path forward right now. Our CLI flags are config fields so you’d have to consider what config makes sense that could also be in a file. Or, consider a new special case.

I don’t yet see this as desirable enough to special case. I’m willing to change my opinion on that if enough people really wanted this. For now, you’re the first I’ve heard.

Given that, i think the best path is the API and you scripting it.

Or feel free to maintain a fork that adds this if you want it directly in Ghostty.
