How do I make sure this displays when I'm working in a container?

[kaosine]

When I enter containers(unless I choose specific themes that I can never recall which do and which don't), I can't tell if I am or not in one and occasionally forget that I am in one. Especially if it's toolbox right now since I've not gotten around to converting vagrant or some other method for having containerized development. But I'd like to prefix it like vanilla fish does(or at least I swear I remember it did?). Just so it's easier to remember and not accidentally exit the terminal completely if I am out of it and forgot.

Can you please elaborate and help me understand what this is about?

I'm on fedora and when in bash it displays
⬢[darsparx@toolbox pulsar-edit.github.io]
where when I've run:
toolbox-enter pulsar-docs
It adds that bit of text to the front(and I think even the default fish config inherits this but these themes don't?). But it seems, unless you use specific themes, that darsparx@toolbox isn't included. I just want that part displayed in some way when looking at the path and branch it has listed:

It depends on the theme you use. It has to support that. Also, you probably need to configure it.

Hey, @fidencio, isn't this already part of the default theme?

[kaosine]

Well, I didn't know how to go about configuring it. Finding information about this stuff is a bit difficult every time I go about searching for it. Since this time, I've got a proper bare git backing stuff up, so hopefully this time it'll be fixed...
