.TH ELVIS 1
|
|
.SH NAME
|
|
celvis, cex, cvi, cview, cinput - The Chinese editor
|
|
.SH SYNOPSIS
|
|
\fBcelvis\fP [\fIflags\fP] [\fB+\fP\fIcmd\fP] [\fIfiles\fP...]
|
|
.SH DESCRIPTION
|
|
\fIElvis\fP is a text editor which emulates \fIvi\fP/\fIex\fP.
|
|
\fICelvis\fP is a Chinese version of \fIelvis\fP.
|
|
It should run on top of some Chinese terminal or Chinese system,
|
|
such as \fIcxterm\fP in X11 window system.
|
|
This version supports both GB encoding and Big5 encoding
|
|
Chinese text.
|
|
.PP
|
|
On systems which pass the program name as an argument, such as Unix and Minix,
|
|
you may also install \fIcelvis\fP under the names
|
|
"cex", "cvi", "cview", and "cinput".
|
|
These extra names would normally be links to celvis;
|
|
see the "ln" shell command.
|
|
.PP
|
|
When \fIcelvis\fP is invoked as "cvi",
|
|
it behaves exactly as though it was invoked as "celvis".
|
|
However, if you invoke \fIcelvis\fP as "cview",
|
|
then the readonly option is set as though you had given it the "-R" flag.
|
|
If you invoke \fIcelvis\fP as "cex",
|
|
then \fIcelvis\fP will start up in the colon command mode
|
|
instead of the visual command mode,
|
|
as though you had given it the "-e" flag.
|
|
If you invoke \fIcelvis\fP as "cinput" or "cedit",
|
|
then \fIcelvis\fP will start up in input mode,
|
|
as though the "-i" flag was given.
|
|
.SH OPTIONS
|
|
.IP \fB-r\fP
|
|
To the real vi, this flag means that a previous edit should be recovered.
|
|
\fICelvis\fP, though, has a separate program, called \fIvirec(1)\fP,
|
|
for recovering files.
|
|
When you invoke \fIcelvis\fP with -r,
|
|
\fIcelvis\fP will tell you to run \fIvirec\fP.
|
|
.IP \fB-R\fP
|
|
This sets the "readonly" option,
|
|
so you won't accidentally overwrite a file.
|
|
.IP "\fB-t\fP \fItag\fP"
|
|
This causes \fIcelvis\fP to start editing at the given tag.
|
|
.IP \fB-e\fP
|
|
\fICelvis\fP will start up in colon command mode.
|
|
.IP \fB-v\fP
|
|
\fICelvis\fP will start up in visual command mode.
|
|
.IP \fB-i\fP
|
|
\fICelvis\fP will start up in input mode.
|
|
.IP "\fB+\fP\fIcommand\fP
|
|
If you use the +\fIcommand\fP parameter,
|
|
then after the first file is loaded
|
|
\fIcommand\fP is executed as an EX command.
|
|
A typical example would be "celvis +237 foo",
|
|
which would cause \fIcelvis\fP to start editing foo and
|
|
then move directly to line 237.
|
|
.SH FILES
|
|
.IP /tmp/elv*
|
|
During editing,
|
|
\fIcelvis\fP stores text in a temporary file.
|
|
For UNIX, this file will usually be stored in the /tmp directory,
|
|
and the first three characters will be "elv".
|
|
For other systems, the temporary files may be stored someplace else;
|
|
see the version-specific section of the documentation.
|
|
.IP tags
|
|
This is the database used by the \fI:tags\fP command and the \fB-t\fP option.
|
|
It is usually created by the \fIctags(1)\fP program.
|
|
.IP ".exrc or elvis.rc"
|
|
On UNIX-like systems, a file called ".exrc" in your home directory
|
|
is executed as a series of \fIex\fR commands.
|
|
A file by the same name may be executed in the current directory, too.
|
|
On non-UNIX systems, ".exrc" is usually an invalid file name;
|
|
there, the initialization file is called "elvis.rc" instead.

|
|
.SH BUGS
|
|
There is no LISP support.
|
|
Certain other features are missing, too.
|
|
.PP
|
|
Auto-indent mode is not quite compatible with the real vi.
|
|
Among other things, 0^D and ^^D don't do what you might expect.
|
|
.PP
|
|
Long lines are displayed differently.
|
|
The real vi wraps long lines onto multiple rows of the screen,
|
|
but \fIcelvis\fP scrolls sideways.

Many other people have worked to port \fIelvis\fP to various operating systems.

To see who deserves credit, run the \fI:version\fP command
|
|
from within \fIcelvis\fP,
