1This is version 2.2.0 (2020-08-01) of nex/nvi, a reimplementation of the ex/vi 2text editors originally distributed as part of the Fourth Berkeley 3Software Distribution (4BSD), by the University of California, Berkeley. 4 5The directory layout is as follows: 6 7 LICENSE .......

Ex/vi documentation. 15 regex ......... Modified regex library with wide character support. 16 vi ............ Vi source code. 17 18=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 19 20o Nvi was written by Keith Bostic, and the last version is 1.79. After that, 21 22 Sven Verdoolaege added the iconv support and the DB3 locking. 23 24 Jun-ichiro itojun Hagino developed the file encoding detection 25 techniques in his nvi-m17n. 26 27The following acknowledgments were written by Keith Bostic: 28 29=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= 30o This software is several years old and is the product of many folks' work. 31 32 This software was originally derived from software contributed to 33 the University of California, Berkeley by Steve Kirkendall, the 34 author of the vi clone elvis. Without his work, this work would 35 have been far more difficult. 36 37 IEEE POSIX 1003.2 style regular expression support is courtesy of 38 Henry Spencer, for which I am *very* grateful. 39 40 Elan Amir did the original 4BSD curses work that made it possible 41 to support a full-screen editor using curses. 42 43 George Neville-Neil added the Tcl interpreter, and the initial 44 interpreter design was his. 45 46 Sven Verdoolaege added the Perl interpreter. 47 48 Rob Mayoff provided the original Cscope support. 49 50o Many, many people suggested enhancements, and provided bug reports and 51 testing, far too many to individually thank. 52 53o From the original vi acknowledgements, by William Joy and Mark Horton: 54 55 Bruce Englar encouraged the early development of this display 56 editor. Peter Kessler helped bring sanity to version 2's 57 command layout. Bill Joy wrote versions 1 and 2.0 through 2.7, 58 and created the framework that users see in the present editor. 59 Mark Horton added macros and other features and made the editor 60 work on a large number of terminals and Unix systems. 61 62o And... 63 The financial support of UUNET Communications Services is gratefully 64 acknowledged. 65
