Show of background jobs

[lourenko]

Hello, I think this even isn't an issue. I'm just trying to migrate from bash to xonsh and my question is if it is possible to configure powerline2 to show the last segment or add an indicator when there are active (or stopped) background jobs in terminal (for example, when I Ctrl+Z in vim). I realize to make a simple stuff like this:

$PL_EXTRA_SEC = {'user': lambda: [' {user} ', 'WHITE', '#555'],
                                  "cwd": lambda: ['{cwd}'+(' ({})'.format(len($(jobs).split("\n"))-1) if len($(jobs).split("\n")) > 1 else ' '), '#000000' if len($(jobs).split("\n")) > 1 else "WHITE", "#fd971f" if len($(jobs).split("\n")) > 1 else "#444"],
                }

Which will change the color of cwd and add the number of jobs in background. But I think the performance of this approach is very poor.

Thank you in advance.

Thx. I've tried something similar myself. But, you're right, it is "bad performance".
I'm hoping we can handle it async/await ... 🤔
