.Sh DESCRIPTION
|
|
||||||
.Nm \&Ex
|
|
||||||
is a line-oriented text editor.
|
|
||||||
.Nm Vi
|
|
||||||
is a screen oriented text editor, based on
|
|
||||||
.Nm ex .
|
|
||||||
.Nm View
|
|
||||||
is the same as using the
|
|
||||||
.Fl R
|
|
||||||
(read-only) option of
|
|
||||||
.Nm vi .
|
|
||||||
.Nm \&Ex
|
|
||||||
and
|
|
||||||
.Nm vi
|
|
||||||
are really different interfaces to the same program,
|
|
||||||
and it is possible to switch back and forth during the same edit session.
|
|
||||||
.Pp
|
|
||||||
This manual page is the one provided with the
|
|
||||||
.Nm nex
|
|
||||||
and
|
|
||||||
.Nm nvi
|
|
||||||
versions of the vi text editors.
|
|
||||||
.Nm Nex
|
|
||||||
and
|
|
||||||
.Nm nvi
|
|
||||||
are intended as bug-for-bug compatible replacements for the original
|
|
||||||
Fourth Berkeley Software Distribution (4BSD)
|
|
||||||
.Nm ex
|
|
||||||
and
|
|
||||||
.Nm vi
|
|
||||||
programs.
|
|
||||||
.Pp
|
|
||||||
The following options are available:
|
|
||||||
.Bl -tag -width indent
|
|
||||||
.It Fl c
|
|
||||||
Execute
|
|
||||||
.Ar command
|
|
||||||
immediately after starting the edit session.
|
|
||||||
Useful for initial positioning in the file, but
|
|
||||||
.Ar command
|
|
||||||
is not limited to positioning commands.
|
|
||||||
This is the POSIX 1003.2 interface for the historic
|
|
||||||
.Dq "+command"
|
|
||||||
syntax.
|
|
||||||
.Nm Nex/nvi
|
|
||||||
supports both the old and new syntax.
|
|
||||||
.It Fl e
|
|
||||||
Start editing in ex mode, as if the command name was
|
|
||||||
.Nm ex .
|
|
||||||
.It Fl F
|
|
||||||
Don't copy the entire file when first starting to edit.
|
|
||||||
(The default is to make a copy in case someone else tries to edit
|
|
||||||
the file too.)
|
|
||||||
.It Fl l
|
|
||||||
List the files that may be recovered using the
|
|
||||||
.Fl r
|
|
||||||
option of
|
|
||||||
.Nm vi .
|
|
||||||
This is the new interface for the historic
|
|
||||||
.Fl r
|
|
||||||
without a file argument syntax.
|
|
||||||
.Nm Nex/nvi
|
|
||||||
supports both the old and new syntax.
|
|
||||||
.It Fl R
|
|
||||||
Start editing in read-only mode, as if the command name was
|
|
||||||
.Nm view .
|
|
||||||
.It Fl r
|
|
||||||
Recover the specified file.
|
|
||||||
.It Fl s
|
|
||||||
Enter batch mode; applicable only to
|
|
||||||
.Nm ex
|
|
||||||
edit sessions.
|
|
||||||
Batch mode is useful when running
|
|
||||||
.Nm ex
|
|
||||||
scripts.
|
|
||||||
Prompts, informative messages and other user oriented things are
|
|
||||||
turned off.
|
|
||||||
This is the POSIX 1003.2 interface for the historic
|
|
||||||
.Fl \-
|
|
||||||
syntax.
|
|
||||||
.Nm Nex/nvi
|
|
||||||
supports both the old and new syntax.
|
|
||||||
.It Fl t
|
|
||||||
Start editing at the specified tag.
|
|
||||||
(See
|
|
||||||
.Xr ctags 1 ).
|
|
||||||
.It Fl w
|
|
||||||
Set the initial window size to the specified number of lines.
|
|
||||||
.It Fl v
|
|
||||||
Start editing in vi mode, as if the command name was
|
|
||||||
.Nm vi
|
|
||||||
or
|
|
||||||
.Nm view .
|
|
||||||
.It Fl x
|
|
||||||
Reserved for X11 interfaces.
|
|
||||||
Not currently implemented.
|
|
||||||
.Sh ADDITIONAL FEATURES
|
|
||||||
This manual page is the one distributed with the
|
|
||||||
.Nm nvi
|
|
||||||
and
|
|
||||||
.Nm nex
|
|
||||||
reimplementations of
|
|
||||||
.Nm ex/vi .
|
|
||||||
There are a few additional features in
|
|
||||||
.Nm nex/nvi .
|
|
||||||
.Bl -tag -width indent
|
|
||||||
.It "8-bit clean data, large lines, files"
|
|
||||||
.Nm Nvi/nex
|
|
||||||
will edit any format file.
|
|
||||||
Line lengths are limited by available memory,
|
|
||||||
and file sizes are limited by available disk space.
|
|
||||||
The command
|
|
||||||
.Dq "^Vx[0-9A-Fa-f]* ,"
|
|
||||||
in input mode, will insert any
|
|
||||||
legal character value into the text.
|
|
||||||
.It "Split screens"
|
|
||||||
The command
|
|
||||||
.Dq ":sp[lit] [file ...]"
|
|
||||||
splits the screen in vi mode.
|
|
||||||
The key
|
|
||||||
.Dq "^W"
|
|
||||||
switches between the foreground screens,
|
|
||||||
and the
|
|
||||||
.Dq ":resize count"
|
|
||||||
command can be used to grow or shrink any
|
|
||||||
particular screen.
|
|
||||||
.It "Background and foreground screens"
|
|
||||||
The command
|
|
||||||
.Dq ":bg"
|
|
||||||
backgrounds the current screen,
|
|
||||||
and the command
|
|
||||||
.Dq ":fg [file]"
|
|
||||||
foregrounds the backgrounded screeen
|
|
||||||
that is editing the specified file, or, by default, the first background
|
|
||||||
screen on the queue.
|
|
||||||
The command
|
|
||||||
.Dq ":di[splay] s[creens]"
|
|
||||||
lists the background screens.
|
|
||||||
.It "Shell screens"
|
|
||||||
The command
|
|
||||||
.Dq ":sc[ript] [file ...]"
|
|
||||||
runs a shell in the screen.
|
|
||||||
Editing is unchanged, with the exception that a <carriage-return>
|
|
||||||
enters the current line (stripped of any prompt) as input to the
|
|
||||||
shell.
|
|
||||||
.It "Tag stacks"
|
|
||||||
Tags are now maintained in a stack.
|
|
||||||
The command
|
|
||||||
.Dq "^T"
|
|
||||||
returns to the previous tag location.
|
|
||||||
The command
|
|
||||||
.Dq ":tagpop [number \| file]"
|
|
||||||
returns to the most recent tag
|
|
||||||
location by default, or, optionally to a specific tag number in the
|
|
||||||
tag stack, or the most recent tag from the specified file.
|
|
||||||
Use the command
|
|
||||||
.Dq ":di[splay] t[ags]"
|
|
||||||
to view the tags stack.
|
|
||||||
The command
|
|
||||||
.Dq ":tagtop"
|
|
||||||
returns to the top of the tag stack.
|
|
||||||
.It "New displays"
|
|
||||||
The command
|
|
||||||
.Dq ":di[splay] b[uffers] \| s[creens] \| t[ags]"
|
|
||||||
can be
|
|
||||||
used to display, respectively, the current cut buffers,
|
|
||||||
the backgrounded screens, and the tags stack.
|
|
||||||
.It "Infinite undo"
|
|
||||||
The changes made during an edit session may be rolled backward and
|
|
||||||
forward.
|
|
||||||
A '.' command immediately after a 'u' command continues either forward
|
|
||||||
or backward depending on whether the 'u' command was an undo or a redo.
|
|
||||||
.It "Usage information"
|
|
||||||
The command
|
|
||||||
.Dq ":exu[sage [cmd]"
|
|
||||||
and
|
|
||||||
.Dq "viu[sage] [key]"
|
|
||||||
provide usage
|
|
||||||
information for all of the ex and vi commands by default, or, optionally,
|
|
||||||
for a specific command or key.
|
|
||||||
.It "Extended regular expressions"
|
|
||||||
The
|
|
||||||
.Dq ":set extended"
|
|
||||||
command treats search and other command regular
|
|
||||||
expressions as extended (egrep(1) style) regular expressions.
|
|
||||||
.It "Word search"
|
|
||||||
The command
|
|
||||||
.Dq "^A"
|
|
||||||
searches for the word referenced by the cursor.
|
|
||||||
.It "Number increment"
|
|
||||||
The command
|
|
||||||
.Dq "#"
|
|
||||||
increments the number referenced by the cursor.
|
|
||||||
.It "Previous file"
|
|
||||||
The command
|
|
||||||
.Dq ":prev[ious][!]"
|
|
||||||
edits the previous file from the
|
|
||||||
argument list.
|
|
||||||
.It "Left-Right scrolling"
|
|
||||||
The command
|
|
||||||
.Dq ":set leftright"
|
|
||||||
makes
|
|
||||||
.Nm nvi
|
|
||||||
do left-right screen scrolling, instead of the traditional
|
|
||||||
.Nm vi
|
|
||||||
line wrapping.
|
|
||||||
.Sh RECOVERY
|
|
||||||
There is no recovery program for nvi, nor does it run setuid.
|
|
||||||
Users may recover any file which they may read, and the superuser
|
|
||||||
may recover any edit session.
|
|
||||||
.Pp
|
|
||||||
Edit sessions are backed by files in
|
|
||||||
.Pa /var/tmp/vi.recover ,
|
|
||||||
and are named
|
|
||||||
.Dq "vi.XXXX" ,
|
|
||||||
where
|
|
||||||
.Dq "XXXX"
|
|
||||||
is a number related to the process id.
|
|
||||||
When a file is first modified, a second file, which contains an
|
|
||||||
email message for the user, is created, and is named
|
|
||||||
.Dq "recover.XXXX" ,
|
|
||||||
where, again,
|
|
||||||
.Dq "XXXX"
|
|
||||||
is associated with the process id.
|
|
||||||
Both files are removed at the end of a normal edit session,
|
|
||||||
but will remain if the edit session is abnormally terminated
|
|
||||||
or the user enters the ex/vi
|
|
||||||
.Dq "preserve"
|
|
||||||
command.
|
|
||||||
The use of the
|
|
||||||
.Pa /var/tmp
|
|
||||||
directory may be changed setting the option
|
|
||||||
.Dq "recdir"
|
|
||||||
in the user's or system startup information.
|
|
||||||
.Pp
|
|
||||||
The recovery directory should have the
|
|
||||||
.Dq "sticky-bit"
|
|
||||||
set so that only the owners of files may remove them.
|
|
||||||
If this is not possible on the system, then a pseudo-user should
|
|
||||||
own the recovery directory.
|
|
||||||
The recovery directory must be both read and write-able by
|
|
||||||
any user.
|
|
||||||
.Pp
|
|
||||||
The recovery file has all of the necessary information in it to enable the
|
|
||||||
user to recover the edit session.
|
|
||||||
In addition, it has all of the necessary email headers for sendmail.
|
|
||||||
When the system is rebooted, all of the files in
|
|
||||||
.Pa /var/tmp/vi.recover
|
|
||||||
named
|
|
||||||
.Dq "recover.XXXX"
|
|
||||||
should be sent by email,
|
|
||||||
using the
|
|
||||||
.Fl t
|
|
||||||
flag of sendmail (or a similar mechanism in other mailers).
|
|
||||||
A simple way to do this is to insert the following script into your
|
|
||||||
rc.local (or other startup) file:
|
|
||||||
.sp
|
|
||||||
.ne 7v
|
|
||||||
.Bd -literal -offset indent -compact
|
|
||||||
# Recover nvi editor files.
|
|
||||||
virecovery=/var/tmp/vi.recover/recover.*
|
|
||||||
if [ "$virecovery" != "/var/tmp/vi.recover/recover.*" ]; then
|
|
||||||
echo 'Recovering vi editor sessions'
|
|
||||||
for i in $virecovery; do
|
|
||||||
sendmail -t < $i
|
|
||||||
done
|
|
||||||
fi
|
|
||||||
.Ed
|
|
||||||
.Pp
|
|
||||||
If
|
|
||||||
.Nm nex/nvi
|
|
||||||
receives a hangup (SIGHUP) signal, it will email the recovery
|
|
||||||
information to the user itself.
|
|
||||||
.Pp
|
|
||||||
If you don't have the sendmail program on your system, the source file
|
|
||||||
.Pa nvi/recover.c
|
|
||||||
will have to be modified to use your mail delivery programs.
