NAME
celvis, cex, cvi, cview, cinput - The Chinese editor
SYNOPSIS
celvis [flags] [*cmd] [files...]
DESCRIPTION
Elvis is a text editor which emulates vi/ex. Celvis is a Chinese
version of elvis. It should run on top of some Chinese terminal or
Chinese system, such as cxterm in X11 window system. This version
supports both GB encoding and Big5 encoding Chinese text.
On systems which pass the program name as an argument, such as Unix and
Minix, you may also install celvis under the names "cex", "cvi",
"cview", and "cinput". These extra names would normally be links to
celvis; see the "ln" shell command.
When celvis is invoked as "cvi", it behaves exactly as though it was
invoked as "celvis". However, if you invoke celvis as "cview", then
the readonly option is set as though you had given it the "-R" flag.
If you invoke celvis as "cex", then celvis 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 celvis as "cinput" or "cedit",
then celvis will start up in input mode, as though the "-i" flag was
given.
OPTIONS
-r To the real vi, this flag means that a previous edit should be
recovered. Celvis, though, has a separate program, called
virec(1), for recovering files. When you invoke celvis with -r,
celvis will tell you to run virec.
-R This sets the "readonly" option, so you won't accidentally
overwrite a file.
-t tag This causes celvis to start editing at the given tag.
-e Celvis will start up in colon command mode.
-v Celvis will start up in visual command mode.
-i Celvis will start up in input mode.
*command
If you use the +command parameter, then after the first file is
loaded command is executed as an EX command. A typical example
would be "celvis +237 foo", which would cause celvis to start
editing foo and then move directly to line 237.
FILES
/tmp/elv*
During editing, celvis 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.
tags This is the database used by the :tags command and the -t
option. It is usually created by the ctags(1) program.
.exrc or elvis.rc
On UNIX-like systems, a file called ".exrc" in your home
directory is executed as a series of ex 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.

BUGS
There is no LISP support. Certain other features are missing, too.
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.
Long lines are displayed differently. The real vi wraps long lines
onto multiple rows of the screen, but celvis scrolls sideways.

Many other people have worked to port elvis to various operating
systems. To see who deserves credit, run the :version command from
within celvis, or look in the system-specific section of the complete
documentation.
The Chinese version, celvis, is developed by Man-Chi Pong (now with the
Hong Kong University of Science and Technology, HK. E-mail:
