Two questions

[Guy Gascoigne-Piggford]

1) Is there a way to change the shell prompt, either by a color or a symbol change to indicate that the user is running with elevated privileges.  The equivalent of switching from $ to # for instance.

2) Is there a way to insert a newline in the prompt? Specifically I want to put a newline before the final $ or #.

Thanks - Guy

It is already done by default by `powerline.segments.common.user`
segment, but detection is limited to “user is (not) root” via UID.

It is possible, using “above” key in theme configuration. Original
issue: https://github.com/powerline/powerline/issues/462,
documentation: http://powerline.readthedocs.io/en/master/configuration/reference.html#config-themes-segments.

Also are you sure you are using powerline? By default there are no
“final $ or #” and while it is possible to do with a proper use of
text segments and colorscheme adjustments, it is rather tricky and
goes against the idea. Normally it just ends with a triangle.

At least on Bash, 'above' doesn't appear to do anything.  My shell theme is:

{
  "default_module": "powerline.segments.common",
  "segments": {
    "above": [
      {
        "left": [
          {
            "function": "powerline.segments.shell.mode",
            "priority": 10
          },
          {
            "function": "powerline.segments.common.net.hostname",
            "args": {
              "only_if_ssh": true,
              "exclude_domain": true
            },
            "priority": 10
          },
          {
            "function": "powerline.segments.common.env.user",
            "priority": 30
          },
          {
            "function": "powerline.segments.shell.cwd",
            "args": {
              "dir_shorten_len": 3,
              "dir_limit_depth": 3,
              "use_path_separator": true
            },
            "priority": 20
          },
          {
            "function": "powerline_gitstatus.gitstatus",
            "priority": 40
          }
        ]
      }
    ]
  }

}

The superuser coloring doesn't appear to work, and I just tested with no local config installed (I moved ~/.config/powerline out of the way).

As for the terminal $ or #, yeah, I know it's not there, I was rather hoping that I could find a way to add it.  We end out with some pretty long branch names here and  it would be nice to avoid truncating them.  I guess the alternative would be to trim them too.

Did you restart the daemon? The above support in bash is being tested:
https://github.com/ZyX-I/powerline/blob/427b2e73623143072f20ffefbfb4f2f7280dc6c2/tests/test_shells/inputs/bash#L59.

It works for me. Though there are ways to have superuser permissions
without UID=0, if this is the case it will not work.

Note that in root powerline should be using root’s config.

id returns a uid of zero.

And above does generate a prompt, it's just indistinguishable from the left one - so no new line at the end of the prompt.

Ah, I get it. In the current state you should have actual left segment
to make it work, just above will not work because of how shell
constructs are processed (prompt is using `PS1="$(…)"` which swallows
all the trailing newlines).
