Elvis

Elvis is an enhanced clone of the vi text editor, first released in January 1990. It introduced several new features, including syntax highlighting and built-in support for viewing nroff and HTML documents. Elvis is written by Steve Kirkendall and is distributed under the Clarified Artistic License (ClArtistic) which is used by Perl and is a GPL-compatible free software license. Elvis is the version of vi that comes with Slackware, Frugalware, and KateOS. Comments Elvis was the pioneering vi clone, widely admired in the 1990s for its conciseness, and many features. It influenced the development of Vim until about 1997. It was the first to provide color syntax highlighting (and to generalize syntax highlighting to multiple file types), first to provide highlighted selections via keyboard.
