# @(#)README 8.147 (Berkeley) 10/19/96
|
|
|
|
This is the README for nex/nvi, a freely redistributable implementation
|
|
of the ex/vi text editors originally distributed as part of the Fourth
|
|
Berkeley Software Distribution (4BSD), by the University of California,
|
|
Berkeley.
|
|
|
|
The source code for nex/nvi can be retrieved by using anonymous ftp to
|
|
ftp.cs.berkeley.edu. The file ucb/4bsd/nvi.tar.gz is the gzip'd archive,
|
|
of version 1.71 of nex/nvi. This version is believed to be stable and
|
|
problem free. The file ucb/4bsd/nvi-###.ALPHA.tar.gz is a gzip'd archive
|
|
of the current alpha-test release of nex/nvi. This version reflects the
|
|
current development tree, and will be more likely to have problems.
|
|
|
|
See the file:
|
|
build/README for information on building nvi.
|
|
LAYOUT for a description of where everything is.
|
|
LICENSE for the copyright and redistribution terms.
|
|
|
|
If you have any questions about nex/nvi, problems with it, or concerns
|
|
about the conditions for redistribution, please contact me:

o This software is several years old and is the product of many folks' work.
|
|
|
|
This software was originally derived from software contributed to
|
|
the University of California, Berkeley by Steve Kirkendall, the
|
|
author of the vi clone elvis. Without his work, this work would
|
|
have been far more difficult.
|
|
|
|
IEEE POSIX 1003.2 style regular expression support is courtesy of
|
|
Henry Spencer, for which I am *very* grateful.
|
|
|
|
Elan Amir did the original 4BSD curses work that made it possible
|
|
to support a full-screen editor using curses.
|
|
|
|
George Neville-Neil added the Tcl interpreter, and the initial
|
|
interpreter design was his.
|
|
|
|
Sven Verdoolaege added the Perl interpreter.
|
|
|
|
Rob Mayoff provided the original Cscope support.
|
|
|
|
o Many, many people suggested enhancements, and provided bug reports and
|
|
testing, far too many to individually thank.
|
|
|
|
o From the original vi acknowledgements, by William Joy and Mark Horton:
|
|
|
|
Bruce Englar encouraged the early development of this display
|
|
editor. Peter Kessler helped bring sanity to version 2's
|
|
command layout. Bill Joy wrote versions 1 and 2.0 through 2.7,
|
|
and created the framework that users see in the present editor.
|
|
Mark Horton added macros and other features and made the editor
|
|
work on a large number of terminals and Unix systems.
|
|
|
|
o And...
|
|
The financial support of UUNET Communications Services is gratefully
|
|
acknowledged.
|
|

|
|
o Status:
|
|
|
|
This software is in beta test, and it's pretty stable. Almost all of the
|
|
historic functionality in ex/vi is there, the only major missing pieces
|
|
are open mode and the lisp edit option.
|
|
|
|
Nvi is largely 8-bit clean. This isn't difficult to fix, and was left in
|
|
during initial development to keep things simple. Wide character support
|
|
will be integrated at the same time that it is made fully 8-bit clean.
|
|
|
|
There aren't a lot of new features in nex/nvi, but there are a few things
|
|
you might like. The "Additional Features" section of the reference work
|
|
(docs/USD.doc/vi.ref/vi.ref.txt, docs/USD.doc/vi.ref/vi.ref.ps) has more
|
|
information.

o Debugging:
|
|
|
|
Code fixes are greatly appreciated, of course, but if you can't provide
|
|
them, please email me as much information as you can as to how I might
|
|
reproduce the bug, and I'll try to fix it locally. Stack traces of core
|
|
dumps are only rarely helpful -- an example file with a set of keystrokes
|
|
that causes the problem is almost invariably necessary. I know it's
|
|
annoying, but simply playing with the bug until you can reproduce it at
|
|
will, with minimal keystrokes, is immensely helpful to me.
|
|
|
|
Please include the following in the bug report;
|
|
|
|
o The version of nvi you're running (use :version to get it).
|
|
o The row/column dimensions of the screen (80 x 32).
|
|
o Unless you're confident that they're not part of the problem,
|
|
your startup files (.exrc, .nexrc) and the environment variable
|
|
(EXINIT, NEXINIT) values. (Cutting and pasting the output
|
|
of ":set all" is usually sufficient.)
|
|
|
|
If you want to do your own debugging, recompile the program with DEBUG
|
|
defined. (Configuring with --enable-debug will do this for you.) This
|
|
turns on the additional command-line option -D, that takes either s or w
|
|
as an argument. The option -Ds causes nvi to ignore the EXINIT and
|
|
.exrc files on startup, and -Dw causes nvi to print out the process id
|
|
and wait for you to enter a <carriage-return> to continue.
|
|
|
|
If you're running a memory checker (e.g. Purify) on nvi, you will first
|
|
want to recompile everything with "-DPURIFY" set in the CFLAGS. This
|
|
initializes allocated pages in the DB code, and free's allocated memory
|
|
at the end of the nvi execution.
