Full window-width bar in transient prompt

[forrestfwilliams]

In my zsh prompt, I would like to make a transient prompt that is a bar which spans the full width of my command prompt window, regardless of window size. Ideally it would look something like this:

I can create this transient prompt using a pre-defined width:

transient_prompt:
  foreground: "#9ece6a"
  template: "{{ repeat 105 \"—\" }}\n"

But I can't figure out how to make the bar length dynamic so that it always fits my window size. Does anyone have suggestions on how I could accomplish this? Thanks!

@forrestfwilliams transient prompt doesn't know about this length. But we do have a feature in a regular prompt called filler that does this for right aligned blocks. I could expose this for transient as well so that it fills the entire line with a set of config defined characters. I can have a look once I'm back from my holidays.

That sounds like a great solution! Yes it would be great to have that option exposed in transient prompts.

@JanDeDobbeleer thanks for the update! I've upgraded to version 14.30.0. Could you confirm that the configuration below should produce a solid line transient prompt? Currently, this configuration only produces a single dash for me.

transient_prompt:
  foreground: "#a9b1d6"
  template: "—\n"
  filler: "—"

I also tried it as:

transient_prompt:
  foreground: "#a9b1d6"
  alignment: right
  template: "—\n"
  filler: "—"

But got the same result.

@forrestfwilliams I'll check on zsh myself

Thanks!

This is a bug in zsh somehow. Will try to find out why that happens.

[JanDeDobbeleer]

@forrestfwilliams this works in all other shells but zsh. It outputs the characters, they're just ignored somehow and I don't see why. I'm going to let this marinate in my head a little bit because I'm starting to question life.

Haha no worries! Sorry to drag you down a rabbit hole!
