Add a space after dropped file/path

[cverond]

When you drag a folder or file its path is copied, but without adding a space. This forces the addition of the space by hand in case you want to compose a command (e.g. cp). MacOS Terminal adds a space each time the path is entered. It would be very convenient to have this behavior in Ghostty as well.

Doing this in all contexts is not necessarily a good idea since you could also drag and drop into say, a text editor window. I think this falls more into shell integration territory since it only makes sense for shells where arguments are delimited by spaces.

Thanks @pluiedev , I definitely hadn't thought of this use-case. It is also true that dragging a path automatically applies the escapes thought for a shell. In that sense I did not think of other scenarios. I don't know if it is possible to think of rules depending on the running process to apply or not some kind of transformation (escaping, adding spaces, ...).

I will say I kind of don't like the behavior of dragging and dropping files because right now I think we always add shell escapes, but as @pluiedev said (and I've considered before), you can drop these anywhere so escaping unconditionally is annoying and prefers the shell.

I've considered -- but didn't follow through -- only shell escaping if we have shell integration and we know we're at a prompt. Otherwise, just letting it through. But that isn't perfect either.

For your specific request, I don't think any other terminal adds a space after a drag and drop, and I tried my best in this case to follow other terminals (since, as I said, the behavior is a bit annoying anyways).

[cverond]

Thanks @mitchellh , I understand that the issue is controversial and depends on the use of the terminal. My observation stems from my habit with macOS Terminal which adds a space at the end of dragged paths, but I have no experience with other terminals.
Thank you anyway for the great work you are doing!

I think what probably needs to happen is a new mode needs to be invented (à la Kitty Keyboard Protocol mode) where the app running in the terminal can signal that it wants more sophisticated handling of dropped files. That mode could then send file paths or whatever else is dropped onto the terminal though some esc codes or some other protocol that can handle more sophisticated encoding.

That's obviously a longer term project that will need coordination among the various terminal developers and the developers of major TUI apps and libraries.

Yeah I was thinking of something analogous to bracketed paste, but for drag-and-drop instead, where programs could specify they want to have "enhanced" drag-and-drop support and the terminal emulator can return DnD results in a special sequence. I thought surely Kitty would do something like this already but it appears that Kovid doesn't want to enhance DnD even further 😅 Maybe it would be down to us this time to invent a protocol then
