eshell-p10k

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

Everything else should already come with emacs

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)
