Removing Tree Sitter
The Tree Sitter just isn't changing anything for me, so I'm removing this code for the time being. I'll reinvestigate later.

*** Tree Sitter
|

Let’s follow along with Mickey Petersen’s [[https://www.masteringemacs.org/article/how-to-get-started-tree-sitter][Getting Started with Tree Sitter]] guide.
|
||||
I’m curious about the new [[https://emacs-tree-sitter.github.io/][Tree Sitter feature]] now [[https://lists.gnu.org/archive/html/emacs-devel/2022-11/msg01443.html][built into Emacs 29]]. After following along with Mickey Petersen’s [[https://www.masteringemacs.org/article/how-to-get-started-tree-sitter][Getting Started with Tree Sitter]] guide, I’ve concluded I /currently/ don’t need this feature. I’m leaving the code here, but adding a =:tangle no= to all the blocks until I’m ready to re-investigate.

*** Evil Text Object from Tree Sitter
