#PC CLONE EX LITE SERIAL KEY MANUAL#
There were some things stolen from ed-we got a manual page for the Toronto version of ed, which I think Rob Pike had something to do with. Dot is really the double-escape from Bravo, the redo command. In an interview about vi's origins, Joy said: Ī lot of the ideas for the screen editing mode were stolen from a Bravo manual I surreptitiously looked at and copied. Īccording to Joy, many of the ideas in this visual mode were taken from Bravo-the bimodal text editor developed at Xerox PARC for the Alto. vi is also the shell command to launch ex/vi in the visual mode directly, from within a shell.
The longform command to do the same was visual, and the name vi is explained as a contraction of visual in later literature. The name vi comes from the abbreviated ex command ( vi) to enter the visual mode from within it.

Vi and ex share their code vi is the ex binary launching with the capability to render the text being edited onto a computer terminal-it is ex's visual mode. After Haley's departure, Bruce Englar encouraged Joy to redesign the editor, which he did June through October 1977 adding a full-screen visual mode to ex -which came to be vi. Inspired by em, and by their own tweaks to ed, Bill Joy and Chuck Haley, both graduate students at UC Berkeley, took code from em to make en, and then "extended" en to create ex version 0.1. Some people considered this new kind of editor to be a potential resource hog, but others, including Bill Joy, were impressed. When Coulouris visited UC Berkeley in the summer of 1976, he brought a DECtape containing em, and showed the editor to various people. It was one of the first programs on Unix to make heavy use of "raw terminal input mode", in which the running program, rather than the terminal device driver, handled all keystrokes. The em editor was designed for display terminals and was a single-line-at-a-time visual editor. Thus it had to fall to someone else to pioneer screen editing for Unix, and that was us initially, and we continued to do so for many years.Ĭoulouris considered the cryptic commands of ed to be only suitable for "immortals", and thus in February 1976, he enhanced ed (using Ken Thompson's ed source as a starting point) to make em (the "editor for mortals" ) while acting as a lecturer at Queen Mary College. You can't run a screen editor on a storage-tube display as the picture can't be updated. They carried on with TTYs and other printing terminals for a long time, and when they did buy screens for everyone, they got Tektronix 4014s. for many years, they had no suitable terminals. Within AT&T Corporation, where ed originated, people seemed to be happy with an editor as basic and unfriendly as ed, George Coulouris recalls: Vi was derived from a sequence of UNIX command line editors, starting with ed, which was a line editor designed to work well on teleprinters, rather than display terminals. īill Joy, the original creator of the vi editor A 2009 survey of Linux Journal readers found that vi was the most widely used text editor among respondents, beating gedit, the second most widely used editor, by nearly a factor of two (36% to 19%).

In addition to various non– free software variants of vi distributed with proprietary implementations of Unix, vi was opensourced with OpenSolaris, and several free and open source software vi clones exist.
The name is pronounced / ˌ v iː ˈ aɪ/ (the English letters v and i). The name "vi" is derived from the shortest unambiguous abbreviation for the ex command visual, which switches the ex line editor to visual mode.
Some current implementations of vi can trace their source code ancestry to Bill Joy others are completely new, largely compatible reimplementations. It was not until version 2.0 of ex, released as part of Second BSD in May 1979 that the editor was installed under the name "vi" (which took users straight into ex's visual mode), and the name by which it is known today. Bill Joy's ex 1.1 was released as part of the first Berkeley Software Distribution (BSD) Unix release in March 1978. The original code for vi was written by Bill Joy in 1976, as the visual mode for a line editor called ex that Joy had written with Chuck Haley.
#PC CLONE EX LITE SERIAL KEY PORTABLE#
The portable subset of the behavior of vi and programs based on it, and the ex editor language supported within these programs, is described by (and thus standardized by) the Single Unix Specification and POSIX. Vi (pronounced as distinct letters, / ˌ v iː ˈ aɪ/) is a screen-oriented text editor originally created for the Unix operating system.
