Description
This allows webconfig to show and save fish_right_prompt if it is defined in a sample (or the current prompt).
It will not remove an existing fish_right_prompt if there is one.
It looks like this:
Fixes issue #736 (at least for fish_right_prompt, I don't think we need more).
In addition (and this is optional, it was just nice to get a better screenshot), this adds a slightly simplified version of my own prompt as the "Disco" sample. Here's a preview:
(the $PWD color depends on the sha of $PWD - this requires sha256sum to be available. if not it'll gracefully fallback to $fish_color_cwd. It will also only show user@host if necessary)
