eshell-p10k is, as the name implies, an eshell version of p10k (a popular shell theme).

Everything else should already come with emacs

Coming Soon™

Add in the load-path somewhere after the dependencies

Some point after eshell has loaded (ideally), use the following options to load the prompt

(setq eshell-prompt-function #'eshell-p10k-prompt-function
        eshell-prompt-regexp eshell-p10k-prompt-string)

Much like p10k itself, it’s possible to change all the start/end/separator characters.

Any characters should work but haven’t been tested

This package includes a somewhat sane prompt out of the box, but also includes a number of tools to create our own segments.

Let’s take a go at our own segment(using an existing face for simplicity)

(eshell-p10k-def-segment time
  ""
  (format-time-string "%H:%M" (current-time))
  'eshell-distro-face)

The eshell-p10k-def-segment macro takes the following basic form:

(eshell-p10k-def-segment segment-name
  icon-to-use
  body
  face)

• segment-name is the defined name of the segment, which will be later used when we define the prompt function
• icon-to-use is the icon which will get prepended to the start of the form. Can also be an expression.
• body is the … body of the segment, which gets evaluated to produce the output. A result of nil will cause the segment to not be displayed.
• face is the face used to display the segment. Can also be an expression.

Now the segment has been created, the prompt definer (eshell-p10k-prompt-function) has to be modified

(defun eshell-p10k-prompt-function ()
  "Prompt defining function."
  (eshell-p10k-def-prompt '(distro dir git prompt-num time)))

And after everything has been re-evaluated, we have the below prompt!

• This article gave me the fundamentals to create the skeleton for this
• doom-modeline for the concept of split segments and adding checks around said segments
• p10k for the inspiration and (and the icons)
