I use ~elpaca~ for package management, and ~use-package~ for configuration management. This means that ~elpaca~ replaces the built-in ~package.el~ functionality.
I use ~elpaca~ for package management, and ~use-package~ for
configuration management. This means that ~elpaca~ replaces the
built-in ~package.el~ functionality.
I do it this way because it simplifies my developement workflow for the emacs-lisp packages I want to contribute to. The built-in ~package.el~ is just fine, and if you prefer that, you should just COMMENT this section, uncomment [[#h:424340cc-f3d7-4083-93c9-d852d40dfd40][The =init.el= settings for packages (=package.el=)]] and re-export all the code-blocks.
I do it this way because it simplifies my developement workflow for
the emacs-lisp packages I want to contribute to, by letting me use
code directly from git forges.
When using ~elpaca~, here are some gotchas you should be aware of
(Note: these only apply for =:ensure t= cases):
1. Use ~elpaca-after-init-hook~ instead of ~after-init-hook~ or
~emacs-startup-hook~. Elpaca runs in the background and does not
guarantee order. Using this special hook ensures that config is
loaded in the expected order.
2. Prefer ~:demand~ or ~:wait~ over ~:defer~, especially when
deferring for a certain number of seconds. Do not make any
assumptions about order of execution.

~treesit-auto~ automatically downloads and installs tree-sitter modules. Tree-sitter is amazing new tech that is built into Emacs from v29 onwards, and enables much better syntax highlighting and code-navigation. I'll write more about tree-sitter in this section at a later date.
