Open Source Emacs-Lisp Emacs Software for Mac

The best editor is neither Emacs nor Vim, it's Emacs *and* Vim, courtesy of Spacemacs! Spacemacs is an extension of the popular text editor Emacs, that offers a whole new way of experiencing Emacs. It is a community-driven Emacs distribution that focuses on ergonomics, mnemonics and consistency. Using it comes naturally to both Emacs and Vim users. In fact, you could even combine the two editing styles. Enabling you to switch between input styles makes Spacemacs a great choice for pair-programming. Spacemacs features a beautiful GUI and exceptional ergonomics, with all the key bindings easily accessible simply by pressing the space bar or alt-m. Spacemacs also comes with hundreds of curated, ready-to-use packages that are well organised in configuration layers.
