Emacs Centered-Point

What is it?

Emacs centered-point mode is a mode that centers the point within an Emacs buffer. This gives you good visual context when you are scrolling to avoid jarring bumps as you work on a piece of code.

Where can I get it?

The code is available on github at: https://github.com/jmercouris/emacs-centered-point

What about emacs-centered-cursor mode?

I've been using the emacs-centered-cursor mode for a long time, and while I am really satisfied with it, it bothered me how much CPU time it seemed to take. In response I developed a plugin that was substantially shorter and used only one line of Elisp code.

What does the code look like?

(define-minor-mode centered-point-mode
  "Alaways center the cursor in the middle of the screen."
  :lighter "..."
  (cond (centered-point-mode (add-hook 'post-command-hook 'line-change))
    (t (remove-hook 'post-command-hook 'line-change)))

(defun line-change ()

What was the journey like?

Along the way I had a lot of great resources that helped me. I strongly recommend the following resources to anyone looking to extend their editor:

The path that I recommend is going through the quick Xah Elisp tutorial, then going through the Emacs minor-mode tutorial, then referencing the Elisp resources until you can finally shape what you need. Looking at my code should even be enough of a simple example to build off and get started. Good luck! Thanks for reading, I hope you enjoyed it!
