Chezmoi and Emacs
- Related pages
I’ve recently wanted to integrate Chezmoi with Emacs, so I can avoid switching
to the terminal or eshell whenever I needed Chezmoi. I’ve searched for a few
Emacs and Chezmoi integration and I found this. However, I wanted to play a
bit with Elisp, so I decided to write my own.
The code is still a work-in-progress, but I already have the basic functionality set up.
chezmoi.el provides three functions: apply, edit and diff – all three run
asynchronously. All logs and diffs are stored in the *chezmoi* buffer.
Further, chezmoi-mode is a minor-mode that sets up keybindings for all three
functions.
The following variables are available: chezmoi-bin, chezmoi-apply and
chezmoi-edit.

These are things I want to implement.
