A way to truncate the current folder name if too long?

[Adam-Kay]

Hi, I'm looking for a way to modify the configuration for the Path segment so that if the folder name is over a certain length it truncates it, preferably with a "...", as some folder names end up taking up too much real estate:

My current configuration is using "style": "folder", but I could not find any properties I could configure for this, besides maybe max_width, but that only seems to work for Powerlevel style.

My current Path segment configuration:

      {
        "type": "path",
        "style": "powerline",
        "powerline_symbol": "\ue0b0",
        "foreground": "p:black",
        "background": "p:yellow",
        "template": " \uea83 {{ path .Path .Location }} ",
        "properties": {
          "style": "folder",
  	  "max_width": 10
        }
      },

Perhaps there is something I can do in the template for this? Sorry, I am still new.

@Adam-Kay You can do this using the template function trunc or abbrev from sprig's string functions.

This is perfect, thank you!

For anyone else who stumbles upon this, I used abbrev and changed my template line to:

"template": " \uea83 {{ path (abbrev 30 .Path) .Location }} ",

which will ensure the folder name can only reach a maximum of 30 characters, including the ... .

I ended up with this segment to keep the prefix and last directory with the beginning trimmed if it exceeds $max, otherwise just present the entire path:

  - options:
      style: full
    template: >-
        {{ $max := 30 }}{{ if le (len .Path) $max }}{{ path .Path .Location }}{{ else }}{{ $p := replace "\\" "/" .Path }}{{ $s := splitList "/" $p }}{{ $root := first $s }}{{ $tail := last $s }}{{ $budget := int (sub $max (add (len $root) 5)) }}{{ if le (len $tail) $budget }}{{ $root }}/.../{{ $tail }}{{ else }}{{ $avail := int (sub $max (add (len $root) 4)) }}{{ $root }}/...{{ trunc (int (mul -1 $avail)) $tail }}{{ end }}{{ end }}
    foreground: "#dddddd"
    powerline_symbol: 
    background: "#0000ff"
    type: path
    style: powerline

Maybe there is a more elegant solution for this, or maybe a new template function could help.

Is there some way to truncate in the middle? With abbrev it shows just the beginning of the path, but I'd like to see at least a part of the beginning and for sure the current working directory. It could be nice if only the middle part could be truncated when it's too long, leaving the 3 dots instead.

No, that's not possible. Would be a custom function to achieve that.
