Jove

JOVE (Jonathan’s Own Version of Emacs) is an open-source ErsatzEmacs implementation.

JOVE is primarily intended for Unix-like operating systems, but also supports MS-DOS and Microsoft Windows. JOVE was inspired by GoslingEmacs? but is much smaller and simpler, lacking any form of LISP or other extension language. It was originally created in 1983 by Jonathan Payne while at Lincoln-Sudbury Regional High School in Massachusetts, USA on a PDP-11 minicomputer. JOVE was distributed with several releases of BSD Unix, including 2.9BSD, 4.3BSD-Reno and 4.4BSD-Lite2.

In 1990 while working at Sun Microsystems JonathanPayne? wrote a series of articles on the comp.editors and comp.emacs newsgroups explaining the benefits of using a “Buffer Gap” technique in the implementation of a text editor. [1] However JOVE still uses a linked-list of pointers to lines of text (stored in a temporary file) with a maximum line length set at compile time.

JOVE is currently maintained by Hugh Redelmeier:
