In the pursuit of an optimized Emacs setup, I focused on enhancing defaults and minimizing the number of installed packages to maintain simplicity and efficiency:

• The initial step involved creating minimal-emacs.d, a project that has resonated with the Emacs community, providing a foundational template for many users’ init.el and early-init.el vanilla Emacs configuration.

• Next, I experimented with hundreds of Emacs packages, carefully selecting the most valuable ones that, ideally, leverage built-in Emacs functions. (This is why I chose corfu chosen over company, eglot over lsp-mode, and flymake over flycheck, etc.)

In this article, I will share the Emacs packages I use daily for software development and text editing. Please share in the comments the Emacs packages you are using!

Where can I find the third-party packages listed below?
