Emacs changes how you think about programming.

Emacs is totally introspectable. You can always find out ‘what code runs when I press this button?’.

Emacs is an incremental programming environment. There’s no edit-compile-run cycle. There isn’t even an edit-run cycle. You can execute snippets of code and gradually turn them into a finished project. There’s no distinction between your editor and your interpreter.

Emacs is a mutable environment. You can set variables, tweak functions with advice, or redefine entire functions. Nothing is off-limits.

Emacs provides functionality without applications. Rather than separate applications, functionality is all integrated into your Emacs instance. Amazingly, this works. Ever wanted to use the same snippet tool for writing C++ classes as well as emails?

Emacs is full of incredible software concepts that haven’t hit the mainstream yet. For example:

• Many platforms have a single item clipboard. Emacs has an infinite clipboard.
• If you undo a change, and then continue editing, you can’t redo the original change. Emacs allows undoing to any historical state, even allowing tree-based exploration of history.
• Emacs supports a reverse variable search: you can find variables with a given value.
• You can perform structural editing of code, allowing you to make changes without breaking syntax. This works for lisps (paredit) and non-lisps (smartparens).
• Many applications use a modal GUI: for example, you can’t do other edits during a find-and-replace operation. Emacs provides recursive editing that allow you to suspend what you’re currently doing, perform other edits, then continue the original task.

Emacs has a documentation culture. Emacs includes a usage manual, a lisp programming manual, pervasive docstrings and even an interactive tutorial.

Emacs has a broad ecosystem. If you want to edit code in a niche language, there’s probably an Emacs package for it.

Emacs doesn’t have a monopoly on good ideas, and there are other great tools out there. Nonetheless, we believe the Emacs learning curve pays off.

This configuration is about Emacs + Evil, but Emacs vanilla key bindings are respected.
