GNU Emacs
Extensible, self-documenting text editor from the GNU Project
GNU Emacs is a free, extensible text editor built around an Emacs Lisp interpreter, so almost every part of it can be reshaped. It supports programming with language servers through Eglot, debugger integration and built-in shells, and many people also use it for Org mode notes and planning, email and file management. Packages install from ELPA archives. It is part of the GNU Project and licensed under the GPL.
