Open new terminal tab in same directory as existing tab (OSC 7?)

[edencorbin]

Description of the new feature/enhancement

Have the option (or default) of a new terminal tab opening in the current directory of the window of which you hit the hotkey to open a new tab. This is the standard way most linux terminals work and is most handy. I often work in a directory where I need to launch multiple seperate processes, its a pain to CD back into the directory each time.

Proposed technical implementation details (optional)

Hit the new tab hotkey, the new terminal should then be in the same folder as the previouse.

This is largely something configurable today, this issue is just tracking another way of configuring this

There's a "standard" escape sequence (OSC 7 ; URI ST) to set the terminal emulator's belief about the current directory. It originates from macOS Terminal.app, and was later adopted by some other ones, including GNOME Terminal and as far as I know Konsole too.

Another possible approach is to do some OS-specific hacks to examine the inner state of the child process (or even further down to descendents).

Yet another possibility is to mix the two, e.g. go to the directory set via OSC 7 if it was ever emitted, otherwise dig into the process.

The advantage of the OSC 7 approach is that it's clever regarding when to and when not to follow a child process. E.g. you start another nested subshell, it'll be the subdirectory of that subshell that's taken into account because that one also emits this sequence. However, launch an app that internally changes directory (e.g. make) and it – luckily – won't be make's internal subdir that's used.

The disadvantage of OSC 7 is that it requires cooperation from the shell, or other apps that matter.

I've been rejecting this feature request for as long as this project has been open-source, and I never learned about OSC 7. This is very exciting.

I'm not happy to crawl through the process tree to dig up the leafmost process's CWD, but I am extremely happy to support OSC 7.
