Running a command in a terminal from another app is a common usecase. Almost all terminals provide such a command execution interface (-e, -x, -- or such). Clients can guess, but they cant know it for sure. If it can break, it will break.

There is a freedesktop spec proposal that tries to standardize the way we configure a default terminal for command execution. It implicitly solves the above problem. Its as simple as that: the app/package provides this info.

To support it you simply need to add X-ExecArgs or ExecArgs (the reference implementation respects both) to the desktop file (like this) and make sure there is TerminalEmulator in Categories. It has not yet been approved (therefore the X-) but hey ExecArgs does not conflict any standard key and if it will be approved you dont have to change it again.

As an elaborative example see how GNOME terminal does it: f1814cb7ec

This will help making Linux a better user experience and a less annoying developer experience.

Thank you

PS:
The draft states that the default will be -e and you might think "okay, done" if your ExecArg is -e. I recommend to add it anyway because then you are on the safe side if the final spec does not fall back to -e. I guess (hope) there will be no default.
You might also think "Why that early if it's a draft?". Correct, but if you do so, I will give you a grateful hug should we ever meet in real life because I am the maintainer of that frustrating list linked in the beginning. If you do so I can wipe your entry from the list ❤️. Also this proposal is a good thing and we should all push it.

Now that I know that there is a related intentapp draft and a terminal intent I'll have to get an opinion before starting discussions.

I though a while about it and also discussed it on the xdg mailing list and came to the conclusion that it makes sense to add it, even in the advent of the terminal intent.
