Support user units

[k0ral]

It seems that systemctl-tui can only work with global units, as opposed to user units (as in: systemctl --user.) It would be nice to be able:

• to switch between global & user mode using a keyboard shortcut
• to choose between global or user mode at start-up using a commandline option (e.g. --user or -u as with systemctl tool)

Would you accept a merge request to that end ? (I'm willing to try and contribute it.)

Thanks for the issue!

I'd rather not have separate modes if we can avoid it; how do you feel about showing both global and user units at the same time?

[k0ral]

I suggested a modal implementation because this is somewhat what systemctl does and I figured you might want to stick to its model. But we could instead use a filter on the "scope" of the unit (for lack of a better word), with 2 possible flags (user & global) and 3 possible combinations (user / global / user | global). What do you think ?

Anyway, to answer your question: showing both global and user units at the same time is already a desirable improvement over the current situation, so I'll take it :slightly_smiling_face: .

Gotcha. I'm OK diverging from systemctl's behaviour here.

Sure, that seems useful. Maybe as a CLI flag like --scope user/--scope global/--scope all, and default to all?

@k0ral Still have any interest in implementing this?

I don't think I'll be able to implement this in a timely manner, I got preempted by other tasks. Feel free to implement it, if that's what you had in mind ; apologies for implying that I was actively working on it.

I've implemented this in https://github.com/rgwood/systemctl-tui/commit/7c92092a5d8c4357f1cb9a131ca149af073ef2cf, sorry for the wait!

Version 0.3.0 now handles global+user services. By default it displays both (and mentions which is which in the details pane), but the --scope CLI flag can be used to only display one of those.
