![]() ![]() On a real Lisp Machine, an Emacs-like text editor is just one application and one interface style. They are Lisp applications which expose a development interface and a development environment (yes, Autocad has Lisp development tools) and users are writing complex applications on top of those. None of the extensible Lisp applications are 'Lisp Machines': not Autocad, not Audacity, not iCAD, not Creo Elements, not GNU Emacs, not OpusModus, not Macsyma. GNU Emacs is a mostly single-threaded editor, with a horrible user interface and heroic efforts from users to deal with thousands of modes and keystroke combinations. ![]() With GNU Emacs the extensibility ends when one calls an OS tool or an OS library - for a Lisp Machine there is no such distinction. A Lisp OS has also an open GUI and not just an editor-buffer-based UI. This means the OS itself is written in Lisp and not just some specialized application, interfacing to a foreign underlying OS. A Lisp machine is a computer with a Lisp OS on the metal. GNU Emacs is an extensible text editor, but not a Lisp Machine. There is, I think, a difference between making a new application that can use neovim for editing some bits and making an old (or, indeed, very old) application switch to using neovim for editing. For all it’s difficulties, having buffer-local variables and dynamic scope seems to make writing extensions easierĪs far as I can tell, making Emacs cooperate with neovim would require shoehorning the editor model of one editor into that of the other, likely causing many extensions and expected behaviours to break. It comes with a built-in web browser, IRC client, calculator, and even Tetris. Language is more dynamic with advice and eval-after-load and such is extensions can play well togetherģ. An extensible and customizable editor that comes with a wide variety of functions for handling not only text but also HTML or source code. Emacs is a text editor, but its so much more than that. Language is more extensible because of macros so dealing with editor state can be hidden.Ģ. This is in comparison to eg vimscript (hopelessly bad) and javascript (extremely mediocre). ![]() A main reason for emacs being good is that it has a good programming language for extensions and good primitives to support it. There are a few text editors available on UNIX, the editors are: EMACS - Gnus version of EMACS - GNU EMACS - Within this editor typing ctrl-H will invoke its. ![]()
