pair-tree.el
A cons cell explorer.
M-x pair-tree is a learning tool for visualizing Emacs Lisp lists.
If you're baffled by cons and confused by cdaadr you might want to give it a spin.
For example
M-x pair-tree '((2 . (turtle doves)) (3 french hens) 4 (calling . birds) partridge)
Requirements
You will need Emacs 27.1 and svg support. Needless to say, this won't work on a terminal.
Installation
Clone this repository and add pair-tree.el to your load path:
(add-to-list load-path "/path/to/repo/pair-tree.el")
Usage
Call M-x pair-tree and type the list you want to visualise.
You can navigate the tree with the arrow keys. The minibuffer shows the most concise accessor for the focused section.
Other resources
If you're learning about lists, be sure to read the GNU Emacs manual. You may want to check out dash.el, the excellent list library used in this package.
