Pure: Higlight slashes in the path to visualize the path components

This is a feature request.

Please, compare these two screenshots:

Personally, I find it useful, and maybe you will like it too.
The method I use is buggy, as it can't handle % anywhere in the path:

diff --git a/pure.zsh b/pure.zsh

I would rather do the inverse and slightly dim the path separators.

So something like preprompt_parts+=('%F{blue}${${(%):-%~}//\//%F{24\}/%f%F{blue\}}%f')? It could be hard to come up with a good dimmed color.

It could be hard to come up with a good dimmed color.

Agree, I played with the background color, but nothing worked for me as good as a simple bold.

@mafredri There's an ansi escape code for dimming: https://github.com/chalk/ansi-styles/blob/f4df7e9fb69f14fc124cae0769fc17065c4413c5/index.js#L26

I've grown into the realization that having the last path component highlighted is more useful for me.

I do it this way:

function cwd() { print ${(D)PWD} }
function path_head() { print ${${"$(cwd)"%/*}} }
function esc_path_tail() { print ${${"$(cwd)"#"$(path_head)"}//\%/%%} } # escape '%'
function esc_path_head() { print ${$(path_head)//\%/%%} } # escape '%'
# ...
preprompt_parts+=('%F{${prompt_pure_colors[path]}}$(esc_path_head)%f%F{12}$(esc_path_tail)%f')
