This document is a guide to quickly setting up the Vim color editor on Linux or Unix systems. The information here will improve the productivity of programmers because the
Vim editor supports syntax color highlighting and bold fonts, improving the
"readability" of program code. A programmer's productivity improves 2 to 3 times
with a color editor like Vim.
The information in this document applies to all operating sytems where Vim
works, such as Linux, Windows 95/NT, Apple Mac, IBM OSes, VMS, BeOS and all flavors of Unix like Solaris, HPUX, AIX, SCO, Sinix, BSD, Ultrix etc.. (it means almost all operating systems on this planet!)

<sect>Introduction
<p>
<bf>
(The latest version of this document is at <url url="http://www.milkywaygalaxy.freeservers.com">. You may
want to check there for changes).
</bf>
Vim stands for 'Vi Improved'. Vi is the most popular and powerful
editors in the Unix world. <bf>Vi</bf> is an abbreviation for "<it><bf>Vi</bf></it>sual" editor.
One of the first editors was a line editor
called 'ed' (and 'ex'). The <it><bf>Vi</bf></it>sual editor
like Vi was a vast improvement over line editors like 'ed' (or 'ex'). The editors 'ed'
and 'ex' are still available on Linux: see 'man ed' and 'man ex'.
<p>
A good editor improves programmer productivity. Vim supports color syntax highlighting of program code and
also emphasises text using different fonts like normal, bold or italics. A color editor like Vim
can improve the <bf>productivity</bf> of programmers by <bf>2 to 3 times</bf>!! Programmers can
read the code much more rapidly as the code syntax is colored and highlighted.
<sect1> Before you Install <label id="Before you Install">
<p>
Before you install Vim, please refer to the OS specific release notes and
information about compiling and usage of Vim at -
<itemize>
<item> Go to this location and look for files os_*.txt <url url="http://cvs.vim.org/cgi-bin/cvsweb/vim/runtime/doc">
</itemize>
If you do not have the Vim package (RPM, DEB, tar, zip) then download
the Vim source code by ftp from the official Vim site
<itemize>
<item> The home page of vim is at <url url="http://www.vim.org">
<item> Mirror site in US is at <url url="http://www.us.vim.org">
<item> Ftp site <url url="ftp://ftp.vim.org/pub/vim">
<item> Or use one of the mirrors <url url ="ftp://ftp.vim.org/pub/vim/MIRRORS">
</itemize>
<sect1> Install Vim on Redhat Linux
<p>
To use Vim install the following RPM packages on Redhat Linux -
<code>
rpm -i vim*.rpm
OR do this -
rpm -i vim-enhanced*.rpm
rpm -i vim-X11*.rpm
rpm -i vim-common*.rpm
rpm -i vim-minimal*.rpm
</code>
You can see the list of files the vim rpm installs by -
<code>
rpm -qa | grep ^vim | xargs rpm -ql | less
or
rpm -qa | grep ^vim | awk '{print "rpm -ql " $1 }' | /bin/sh | less
</code>
and browse output using j,k, CTRL+f, CTRL+D, CTRL+B, CTRL+U or using arrow keys, page up/down keys.
See 'man less'.
<p>
Note that the RPM packages for Redhat Linux use a Motif interface. If you have installed the
GTK libraries on your system, consider compiling Vim from the source code for a clean
GUI interface. For information on compiling Vim from the source code, see "Install Vim on Unixes", below.
<sect1> Install Vim on Debian GNU/Linux
<p>
To install Vim on Debian Linux (GNU Linux), login as root and when connected to internet
type -
<code>
apt-get install vim vim-rt
</code>
It will download the latest version of vim, install it, configure it.
The first package listed is vim, the standard editor, compiled
with X11 support, vim-rt is the vim runtime, it holds all the syntax and help files.
<p>
On Debian 3.0 (woody) and above, use 'apt-get install vim' instead.
The vim-rt package is part of the main vim package.
<sect1> Install Vim on Unixes
<p>
For other flavors of unixes like Solaris, HPUX, AIX, Sinix, SCO download the source code file
( see
<ref id="Before you Install">
)
<code>
zcat vim.tar.gz | tar -xvf -
cd vim-5.5/src
./configure --prefix=$HOME/local
make
make install
</code>
You can exclude prefix option if you want to install in default location in /usr/local.
If the graphics version 'gvim' gives trouble then try with
<code>
./configure --prefix=$HOME/local --enable-gui=motif
</code>
<p>
<sect1> Install Vim on Microsoft Windows 95/NT
<p>
See <ref id="installmswin" name="Install on MS Windows">.
<sect1> Install Vim on VMS
<p>
<sect2> Download files
<p>
You will need both the Unix and Extra archives to build vim.exe for VMS.
For using Vim's full power you will need the runtime files as well.
Get these files
( see
<ref id="Before you Install">
)
You can download precompiled executables from:

</itemize>
<sect2> Compiling
<p>
Unpack the Unix and Extra archives together into one directory. In the <.SRC>
subdirectory you should find the make file OS_VMS.MMS. By editing this file
you may choose between building the character, GUI and debug version. There
are also additional options for Perl, Python and Tcl support.
You will need either the DECSET mms utility or the freely available clone of
it called mmk (VMS has no make utility in the standard distribution). You can
download mmk from http://www.openvms.digital.com/freeware/MMK/
If you have MSS on your system, the command
> mms /descrip=os_vms.mms
will start building your own customised version of Vim.
The equivalent command for mmk is:
> mmk /descrip=os_vms.mms
<sect2> Deploy
<p>
Vim uses a special directory structure to hold the document and runtime files:
<code>
vim (or wherever)
|- tmp
|- vim55
|----- doc
|----- syntax
|- vim56
|----- doc
|----- syntax
vimrc (system rc files)
gvimrc
Use:
> define/nolog device:[leading-path-here.vim] vim
> define/nolog device:[leading-path-here.vim.vim56] vimruntime
> define/nolog device:[leading-path-here.tmp] tmp
</code>
to get vim.exe to find its document, filetype, and syntax files, and to
specify a directory where temporary files will be located. Copy the "runtime"
subdirectory of the vim distribution to vimruntime.
Note: Logicals $VIMRUNTIME and $TMP are optional. Read more at :help runtime
<sect2> Practical usage
<p>
Usually you want to run just one version of Vim on your system, therefore
it is enough to dedicate one directory for Vim.
Copy all Vim runtime directory structure to the deployment position.
Add the following lines to your LOGIN.COM (in SYS$LOGIN directory).
Set up logical $VIM as:
<code>
> $ define VIM device: <path>
</code>
Set up some symbols:
<code>
> $ ! vi starts Vim in chr. mode.
> $ vi*m :== mcr device:<path>VIM.EXE
> $ !gvi starts Vim in GUI mode.
> $ gv*im :== spawn/nowait mcr device:<path>VIM.EXE -g
</code>
Create .vimrc and .gvimrc files in your home directory (SYS$LOGIN).
The easiest way is just rename example files. You may leave the menu file
(MENU.VIM) and files vimrc and gvimrc in the original $VIM directory. It will
be default setup for all users, and for users is enough just to have their
own additions or resetting in home directory in files .vimrc and .gvimrc.
It should work without problems.
Note: Remember, system rc files (default for all users) do not have the leading
"." So, system rc files are:
<code>
> VIM$:vimrc
> VIM$:gvimrc
> VIM$:menu.vim
</code>
and user's customised rc files are:
<code>
> sys$login:.vimrc
> sys$login:.gvimrc
</code>
You can check that everything is on the right place with the :version command.
<code>
Example LOGIN.COM:
> $ define/nolog VIM RF10:[UTIL.VIM]
> $ vi*m :== mcr VIM:VIM.EXE
> $ gv*im :== spawn/nowait mcr VIM:VIM.EXE -g
> $ set disp/create/node=192.168.5.223/trans=tcpip
</code>
Note: This set-up should be enough if you are working in a standalone server or
clustered environment, but if you want to use Vim as an internode editor, it
should suffice. You just have to define the "whole" path:
<code>
> $ define VIM "<server_name>[""user password""]::device:<path>"
> $ vi*m :== "mcr VIM:VIM.EXE"
</code>
as for example:
<code>
> $ define VIM "PLUTO::RF10:[UTIL.VIM]"
> $ define VIM "PLUTO""ZAY mypass""::RF10:[UTIL.VIM]" ! if passwd required
</code>
You can also use $VIMRUNTIME logical to point to proper version of Vim if you
have multiple versions installed at the same time. If $VIMRUNTIME is not defined
Vim will borrow value from $VIM logical. You can find more information about
$VIMRUNTIME logical by typing :help runtime as a Vim command.
<sect2> GUI mode questions
<p>
VMS is not a native X window environment, so you can not start Vim in GUI mode
"just like that". But it is not too complicated to get a running Vim.
<code>
1) If you are working on the VMS X console:
Start Vim with the command:
> $ mc device:<path>VIM.EXE -g
or type :gui as a command to the Vim command prompt. For more info :help gui
2) If you are working on other X window environment as Unix or some remote X
VMS console. Set up display to your host with:
> $ set disp/create/node=<your IP address>/trans=<transport-name>
and start Vim as in point 1. You can find more help in VMS documentation or
type: help set disp in VMS prompt.
Examples:
> $ set disp/create/node=192.168.5.159 ! default trans is DECnet
> $ set disp/create/node=192.168.5.159/trans=tcpip ! TCP/IP network
> $ set disp/create/node=192.168.5.159/trans=local ! display on the same node
</code>
Note: you should define just one of these.
For more information type $help set disp in VMS prompt.
<sect1> Install Vim on OS/2
<p>
Read the release notes for Vim on OS/2, see
<ref id="Before you Install">
.
At present there is no native PM version of the GUI version of vim: The OS/2
version is a console application. However, there is now a Win32s-compatible
GUI version, which should be usable by owners of Warp 4 (which supports
Win32s) in a Win-OS/2 session. The notes in this file refer to the native
console version.
To run Vim, you need the emx runtime environment (at least rev. 0.9b). This
is generally available as (ask Archie about it):
<code>
emxrt.zip emx runtime package
</code>

Vim compiles out of the box with the supplied CodeWarrior project when using
CodeWarrior 9. If you are using a more recent version (e. g. CW Pro) you have
to convert the project first.
When compiling Vim for 68k Macs you have to open the "size" resource in
ResEdit and enable the "High level events aware" button to get drag and drop
working.
You have to increase the memory partition to at least 1024 kBytes to prevent
Vim from crashing due to low memory.

<sect> Install Vim on Microsoft Windows 95/NT <label id="installmswin">
<p>
For Windows 95/NT, download the Vim zip file.
Double click on the vim.exe and <bf>do "FULL"
install and not "Typical"</bf> to get graphics and colors.
If you decide download in parts, then you must download <bf>TWO</bf> zip files -
<itemize>
<item> Runtime support file <bf>vim*rt.zip</bf>
<item> Vim command file <bf>vim*60.zip</bf>. Where Vim version is 5.6.
</itemize>
Get one big executable or two zip files from:
Goto <url url="http://www.vim.org"> and click on
Download-> download FAQ-> Windows 95/NT or click on these
<url url="ftp://vim.ftp.fu-berlin.de/pc/gvim60.zip"> and
<url url="ftp://vim.ftp.fu-berlin.de/pc/vim60rt.zip">.
( see also
<ref id="Before you Install">
)
Unpack the zip files using the Winzip <url url="http://www.winzip.com">.
Both the zip files (vim*rt.zip and vim*60.zip) must be unpacked
in the same directory like say <bf>c:\vim</bf>.
For Windows 95/98, set the environment variable VIM (all caps no lowercase) in
autoexec.bat by adding this line -
<code>
set VIM=c:\vim\vim60
</code>
For Windows NT, add the environment variable VIM (all caps no lowercase) to the
<bf>Start | Control Panel | System | Environment | System Properties</bf> dialog.
For Windows 2000, click on
<bf>Start | Control Panel | System | Advanced | Environment Variable</bf> dialog
and add variable VIM (all caps no lowercase):
<code>
VIM=c:\vim\vim60
</code>
The VIM variable should point to wherever you installed the vim60 directory.
You can also set your PATH to include the gvim.exe's path.
You may need to logoff and relogin to set your environment. Bring up a MS-DOS window by
click on Start->Programs->MSDOS (for Windows 95/98) and Start->Run->cmd (for Windows NT/2000).
At an MS-DOS prompt type -
<code>
c:\> set vim
c:\> cd vim\vim60
c:\> install.exe
</code>
For 'set vim' command, you should see - VIM=c:\vim\vim60 and start the install program
which will setup the enviroment.
Create a short-cut on to your desktop by click-and-drag
from c:\vim\vim60\gvim.exe.
<bf>Color Syntax Highlighting: </bf> To enable color syntaxt highlighting and
other nice features you must copy the gvimrc_example file to
the $VIM\_gvimrc. In my case it is c:\vim\vim60\_gvimrc.
<code>
c:\> copy c:\vim\vim60\gvimrc_example $VIM\_gvimrc
</code>
<bf>Useful Tips : </bf>
<itemize>
<item>Just double click on gvim icon on desktop and
click MyComputer->C:drive->Select a file and drag and drop it into the gvim window.
The file is automatically opened by gvim window!!
<p>
<item> To automatically maximize the Vim window in MS Windows, you can use
<url url="http://www.southbaypc.com/AutoSizer"> or you can right click on Gvim shortcut
and select properties and pick maximize the window on startup.
</itemize>
<sect1> Install bash shell
<p>
In order make MS Windows 95/98/NT/2000/XP even more user-friendly, install the
bash shell (Bourne Again Shell). Install
<url url="http://sources.redhat.com/cygwin/setup.exe">
(Cygwin-setup program) and select bash and other common utilities.
The CygWin main site is at <url url="http://sources.redhat.com/cygwin">.
With CygWin the Windows 2000 computer will look like Linux/Unix box!!
And combined with gvim editor, the Windows 2000 gives programmers more power.
The cygwin home is at <url url="http://cygwin.com">.
You may also want to install MKS in case you are planning to use Java and
Java compilers. Get MKS from <url url="http://www.mks.com">.
<sect1> Edit bash_profile
<p>
After installing the Cygwin, insert some useful aliases in ~/.bash_profile file.
Open a cygwin window and at bash prompt -
<code>
bash$ cd $HOME
bash$ gvim .bash_profile
set -o vi
alias ls='ls --color '
alias cp='cp -i '
alias mv='mv -i '
alias rm='rm -i '
alias vi='gvim '
alias vip='gvim ~/.bash_profile & '
alias sop='. ~/.bash_profile '
alias mys='mysql -uroot -p '
PATH=$PATH:"/cygdrive/c/Program Files/mysql/bin"
</code>
With color ls, when you do ls you will see all the directory names and files in
different colors (it looks great!!).
With set -o vi, you can use the command line history editing just as in linux.
<sect1> Setup Window colors
<p>
The default background color of MS DOS prompt window is black and white text.
You must change the color, fontsize and window size to make it more pleasing.
On MS Windows 2000, click on button Start->Run and type "cmd" and hit return.
On MS Windows 95/98/NT click on Start->Programs->MSDOS Prompt which will
bring up MSDOS window.
Right click on the top left corner of the MSDOS prompt window and select properties.
Select color background and enter R=255, G=255, B=190 (red, green, blue) for
lightyellow background
and text foreground color to black (R=0, G=0, B=0).
This sets background to light yellow and text foreground to black and this
combination is most pleasing to human eyes.
If you have problems with colors in cygwin bash window when doing 'man ls', set the
text color to "marune".
For Windows95 see <url name="Color for MS-DOS prompt window" url="http://www.elementkjournals.com/w95/9711/w9597b3.htm">.
<sect> Setup gvim init files
<p>
To enable the syntax color highlighting you MUST copy the gvimrc file to
your home directory. This will also put the "Syntax" Menu with gvim command.
You can click on Syntax Menu and select appropriate languages like C++, Perl, Java, SQL, ESQL etc..
<CODE>
cd $HOME
cp /usr/doc/vim-common-5.3/gvimrc_example ~/.gvimrc
</CODE>
Comment lines in .gvimrc begin with double-quotes (").
You can customize gvim by editing the file $HOME/.gvimrc and put the following lines -
<CODE>
" This line is a comment .... one which begins with double-quotes
" The best is the bold font, try all of these and pick one....
set guifont=8x13bold
"set guifont=9x15bold
"set guifont=7x14bold
"set guifont=7x13bold
"
" Highly recommended to set tab keys to 4 spaces
set tabstop=4
set shiftwidth=4
"
" The opposite is 'set wrapscan' while searching for strings....
set nowrapscan
"
" The opposite is set noignorecase
set ignorecase
set autoindent
"
" You may want to turn off the beep sounds (if you want quite) with visual bell
" set vb
" Source in your custom filetypes as given below -
" so $HOME/vim/myfiletypes.vim
</CODE>
It is <bf>very strongly</bf> recommended that you set the <it>tabstop</it> to 4 and
<it>shiftwidth</it> to 4.
The <it>tabstop</it> is the number of spaces the TAB key will indent while editing with gvim. The
<it>shiftwidth</it> is the number of spaces the lines will be
shifted with "&gt;&gt;" or "&lt;&lt;" vi commands. Refer to Vi
tutorials
<ref id="Vim Tutorial">
for more details.
To see the list of available fonts on Linux/Unix see
the command <bf>xlsfonts</bf>. Type -
<code>
bash$ xlsfonts | less
bash$ xlsfonts | grep -i bold | grep x
bash$ man xlsfonts
</code>
<sect1> Sample gvimrc file
<p>
You can change the settings like color, bold/normal fonts in your $HOME/.gvimrc file.
It is <bf>very strongly</bf> recommended that you set the background color
to <it>lightyellow</it> or <it>white</it> with <it>black</it> foreground. Ergonomics says
that best background color is
<it>lightyellow</it> or <it>white</it> with <it>black</it> foreground. Hence change
the variable 'guibg' in your $HOME/.gvimrc file as follows:
<code>
highlight Normal guibg=lightyellow
</code>
The sample gvimrc from /usr/doc/vim-common-5.3/gvimrc_example is as follows:
<CODE>
" Vim
" An example for a gvimrc file.
" The commands in this are executed when the GUI is started.
"
" To use it, copy it to
" for Unix and OS/2: ~/.gvimrc

" for MS-DOS and Win32: $VIM\_gvimrc
" Make external commands work through a pipe instead of a pseudo-tty
"set noguipty
" set the X11 font to use. See 'man xlsfonts' on unix/linux
" set guifont=-misc-fixed-medium-r-normal--14-130-75-75-c-70-iso8859-1

endif
</CODE>

<sect1> Xdefaults parameters
<p>
You can set some of the Vim properties in Xdefaults file.
<bf> WARNING: </bf><it>Do not set <bf>Vim*geometry</bf> as it will break the gvim menu, use <bf>Vim.geometry</bf> instead</it>.
Edit the $HOME/.Xdefaults file and add the following lines:
<CODE>
! GVim great Colors.
Vim*useSchemes: all
Vim*sgiMode: true
Vim*useEnhancedFSB: true
Vim.foreground: Black
!Vim.background: lightyellow2
Vim*background: white
! Do NOT use Vim*geometry , this will break the menus instead
! use Vim.geometry. Asterisk between Vim and geometry is not allowed.
! Vim.geometry: widthxheight
Vim.geometry: 88x40
!Vim*font: -misc-fixed-medium-r-normal--20-200-75-75-c-100-iso8859-15-*5
Vim*menuBackground: yellow
Vim*menuForeground: black
</CODE>
In order for this change to take effect, type -
<code>
xrdb -merge $HOME/.Xdefaults
man xrdb
</code>
You can also edit the &tilde/.gvimrc file to change the background colors
<CODE>
gvim $HOME/.gvimrc
The best background color is lightyellow or white, with black foreground.
highlight Normal guibg=lightyellow
</CODE>
<sect> Color Syntax init files
<p>
<sect1> Auto source-in method
<p>
This section below is obtained from gvim session by typing 'help syntax' -
<code>
bash$ gvim some_test
:help syntax
</code>
Click on the menu Window=>Close_Others to close other Window. And then do CTRL+] on 'Syntax Loading Procedure' menu which will take you there.
(Use CTRL+T to rewind and go back).
If a file type you want to use is not detected, then there are two ways to
add it.
<bf>Method 1: </bf> You can modify the <it>$VIMRUNTIME/filetype.vim</it> file,
but this is not recommended as it will be overwritten when you
install a new version of Vim.
<bf> Method 2: </bf> Create a file in $HOME/vim/myfiletypes.vim and put
these lines in it -
<code>

" so $HOME/vim/myfiletypes.vim
"
" *************************************************************
augroup filetype
au!
au! BufRead,BufNewFile *.phc set filetype=php
au! BufRead,BufNewFile *.mine set filetype=mine
au! BufRead,BufNewFile *.xyz set filetype=drawing
au! BufRead,BufNewFile *.prc set filetype=plsql
augroup END
</code>
Then add a line in your $HOME/.vimrc and $HOME/.gvimrc file to source
in the file "myfiletypes.vim".
(<bf>CAUTION:</bf> You MUST put this in both vimrc and gvimrc files
in order for this to work) Example:
<code>
so $HOME/vim/myfiletypes.vim
</code>
<bf>NOTE:</bf> Make sure that you set "so myfiletypes.vim" before switching on file type
detection. This is must be before any ":filetype on" or ":syntax on"
command.
See the documentation on autocommand at -
<itemize>
<item><bf>:help autocmd</bf> (within a vim editing session)
<item>See also the doc at /usr/share/vim/doc/autocmd.txt
</itemize>
Your file will then be sourced in after the default FileType autocommands have
been installed. This allows you to overrule any of the defaults, by using
":au!" to remove any existing FileType autocommands for the same pattern.
Only the autocommand to source the scripts.vim file is given later. This
makes sure that your autocommands in "myfiletypes.vim" are used before
checking the contents of the file.
<sect1> Manual method
<p>
Instead of using "Syntax" menu you can also
manually source in the syntax file. Edit the file with gvim
and at : (colon) command give 'so' command. For example -
<CODE>
gvim foo.pc
:so $VIM/syntax/esqlc.vim
</CODE>
The syntax source files are at /usr/share/vim/syntax/*.vim. Vim supports more
than 120 different syntax files for different languages like C++, PERL, VHDL, JavaScript,...and so on!!
Each syntax file supports one or more default file name extensions, for example, JavaScript syntax
file supports the *.js extension. If you happen to use an extension that conflicts with
another default syntax file (such as adding JavaScript to a *.html file) than you can source in
the additional syntax file with the command :so $VIM/syntax/javascript.vim.
To avoid all of this typing, you can create a soft link like -
<code>
ln -s $VIM/syntax/javascript.vim js
gvim foo.html (... this file contains javascript functions and HTML)
:so js
</code>
<sect> VIM Usage
<p>
You can use Vim in two modes - one with GUI and other without GUI.
To use GUI use command -
<CODE>
gvim foo.cpp
</CODE>
To use non-gui mode give -
<CODE>
vim foo.cpp
OR plain vanilla mode
vi foo.cpp
</CODE>
It is very strongly recommended that you always use gvim instead of vim, since GUI mode
with colors will definitely improve your productivity.
The vim also gives colors but cannot set the background colors and gvim can set the
background and foreground colors.
GUI mode gvim provides the following -
<itemize>
<item> You can mark the text using the mouse to do cut, copy and paste.
<item> You can use the Menu bar which has - File, Edit, Window, Tools, Synatx and Help buttons.
<item> Also in near future in gvim - a second menu bar will display the list of files being edited,
and you can switch files by clicking on the filenames, until then you can use
vi commands - :e#, :e#1, :e#2, :e#3, :e#4, ....so on to select the files.
</itemize>
<sect> Remote Vi - MS Windows QVWM Manager
<p>
QVWM Window Manager is the best as it is very similar in appearance to Microsoft Windows.
If you want to use Vi and Vim remotely from a MS Windows PC client, then
you should use VNC + QVWM manager. Servers are generally located
in remote Data Centers and to edit the files, you should first login
to remote servers from MS Windows or Linux desktop PCs.
After starting VNC server and QVWM manager on remote server, you should
fire up <bf>vncviewer</bf> on your client desktop and edit remote files
with <bf>gvim</bf>.
To use graphical editor like <bf>gvim</bf> for remote operations, use the
following techniques below:
You can use the VNC to display remote machines on your local display.
<itemize>
<item> The VNC is at <url url="http://www.uk.research.att.com/vnc">
and commercial VNC is at <url url="http://www.realvnc.com">
<p>
<item> Get VNC rpms from
<url name="rpmfind" url="http://rpmfind.net/linux/rpm2html/search.php?query=vnc">
or from commercial VNC at <url url="http://www.realvnc.com">
<p>
<item> The best Window manager for VNC is QVWM which is like MS Windows 98/NT/2000 interface, get
it from <url url="http://www.qvwm.org">.
<p>
<item> After starting vncserver, you can start the <bf>vncviewer</bf> program on clients
like MS Windows, Mac or Linux.
<p>
<item> See also the
<url name="List of X11 Windows Managers" url="http://www.dlhoffman.com/publiclibrary/RPM/X11_Window_Managers.html">.
</itemize>
<bf>Compiling qvwm on Solaris : </bf>
On Solaris you should install the following packages which you can get
from <url url="http://sun.freeware.com"> - xpm, imlib, jpeg, libungif, giflib (giftran),
libpng, tiff.
And you can download the binary package for solaris from
<url url="http://www.qvwm.org">.
Or you can download the qvwm source for solaris from
<url url="http://www.qvwm.org"> and compile it using gcc.
If mainsite is busy use the mirror sites listed there.
Click on the link "The latest version of qvwm is [ftp/http]" to
download the source code.
Troubleshooting the compile:
<itemize>
<item> You must install all the packages listed - xpm, imlib, jpeg, libungif,
giflib, libpng, tiff. Otherwise src will not compile
<item> Must edit the src/util.cc file and change snprintf to printf to compile
the program to get rid of the compile errors.
<item>You should put unsigned long before arg in usleep()
usleep((unsigned long) 10000)
<item> Still problems then see
<url url="http://www.milkywaygalaxy.freeservers.com/vnc"> for compile instructions.
</itemize>
For transferring files from Unix to MS Windows use the ftp clients like
<itemize>
<item> Commercial :

<sect> Vi companions
<p>
Generally Vim is used in conjunction with other powerful
tools like <bf>ctags</bf> and <bf>gdb</bf>. <bf>ctags</bf> is for very rapid navigation
through millions of lines of "C/C++" code and <bf>gdb</bf> is for debugging the "C/C++" code.
A brief introduction of these two indispensable commands will be given in this chapter.
<p>
<bf>ctags</bf> is the most powerful command available for coding C, C++, Java, Perl,
Korn/Bourne shell scripts or Fortran. Developers very extensively use <bf>ctags</bf> to
navigate through thousands of functions within C/C++ programs. See 'man ctags' on Unix.
It is <bf>very important</bf> that you learn how to use ctags to
develop programs in C or C++, Java, etc.. Navigation is the single most important task while
doing development of C or C++ code. Using ctags you can very quickly read the code
by jumping from a calling line to the called function, drill down deeper into nested function calls,
and unwind back all the way up to the top. You can go back and forth from function to function
very quickly.
Without NAVIGATION you will be completely lost! <bf>ctags</bf> is like the magnetic COMPASS
needle for the programmers.
Usage of <bf>ctags</bf> :
<code>
ctags *.cpp
gvim -t foo_function
gvim -t main
</code>
This will edit the C++ program file which contains the function foo_function() and will
automatically place the cursor on the first line of the function foo_function(). The second
command takes you to the line with the main() function definition.
Inside the Vim editor, you can jump to a function by typing : (colon) tag &lt function name &gt
as below -
<code>
:tag sample_function
</code>
This will place the cursor on first line of sample_function()
If you want to jump into the function from a line in file which contains the function name, place the
cursor just before the function name and press <bf>CTRL+]</bf> (press control key and
left-square-bracket key simultaneously).
<code>
// example code
switch(id_number) {
Case 1:
if ( foo_function( 22, "abcef") == 3 )
^
|
|
|
Place the cursor here (just before foo_function) and press CTRL+]
This takes you to the function named "foo_function".
To come back to this line press CTRL+t
</code>
To go back to the calling line press <bf>CTRL+t</bf> (Control key and letter 't' together). Keep pressing <bf>CTRL+t</bf>
to unwind and go to the first line where you started the navigation. That is you can keep pressing <bf>CTRL+]</bf>
and then keep pressing <bf>CTRL+t</bf> to go back. You can repeat these as many times as you want to have complete
navigation through all the functions of C or C++.
<sect1> Directory Tree 'tags'
<p>
To recursively process the tags file for the entire directory :
<code>
$ cd $HOME
$ ctags -R
</code>
This will recurse the directory underneath and create a tag file all the files
under the directory and beneath. But to use this tag file you must set the following
in the vim session or modify .gvimrc file
<code>
$ vi ~/.gvimrc
" Set the tag file search order
set tags=./tags,tags,~/tags,/home/john/ccplus/tags
</code>
Or in the Vim session you set the tags with colon command:
<code>
$ vi somefile.cpp
:set tags=./tags,tags,~/tags,/home/john/ccplus/tags
</code>
<sect1> Ctags for ESQL
<p>
Since ctags does not directly support the Embedded SQL/C (ESQL) language, the following shell script
can be used to create tags for esql. ESQL/C is database SQL commands embedded inside the "C" programs.
Oracle's ESQL/C is called Pro*C and Sybase, Informix have ESQL/C and PostgreSQL has product "ecpg".
<p>
Save this file as "sqltags.sh" and do chmod a+rx tags_gen.sh.
<code>
#!/bin/sh
# Program to create ctags for ESQL, C++ and C files
ESQL_EXTN=pc
tag_file1=tags_file.1
tag_file2=tags_file.2
which_tag=ctags
rm -f $tag_file1 $tag_file2 tags
aa=`ls *.$ESQL_EXTN`
#echo $aa
for ii in $aa
do
#echo $ii
jj=`echo $ii | cut -d'.' -f1`
#echo $jj
if [ ! -f $jj.cpp ]; then
echo " "
echo " "
echo "***********************************************"
echo "ESQL *.cpp files does not exist.. "
echo "You must generate the *.cpp from *.pc file"
echo "using the Oracle Pro*C pre-compiler or Sybase"
echo "or Informix esql/c pre-compiler."
echo "And then re-run this command"
echo "***********************************************"
echo " "
exit
fi
rm -f tags
$which_tag $jj.cpp
kk=s/$jj\.cpp/$jj\.pc/g
#echo $kk > sed.tmp
#sed -f sed.tmp tags >> $tag_file1
#sed -e's/sample\.cpp/sample\.pc/g' tags >> $tag_file1
sed -e $kk tags >> $tag_file1
done
# Now handle all the C++/C files - exclude the ESQL *.cpp files
rm -f tags $tag_file2
bb=`ls *.cpp *.c`
aa=`ls *.$ESQL_EXTN`
for mm in $bb
do
ee=`echo $mm | cut -d'.' -f1`
file_type="NOT_ESQL"
# Exclude the ESQL *.cpp and *.c files
for nn in $aa
do
dd=`echo $nn | cut -d'.' -f1`
if [ "$dd" = "$ee" ]; then
file_type="ESQL"
break
fi
done
if [ "$file_type" = "ESQL" ]; then
continue
fi
rm -f tags
$which_tag $mm
cat tags >> $tag_file2
done
mv -f $tag_file2 tags
cat $tag_file1 >> tags
rm -f $tag_file1
# Must sort tags file for it work properly ....
sort tags > $tag_file1
mv $tag_file1 tags
</code>
<sect1> Ctags for JavaScript programs, Korn, Bourne shells
<p>
The shell script given below can be used to generate tags for a very large variety of programs
written in JavaScript, PHP/FI scripts, Korn shell, C shell, Bourne shell and many others. This is
a very generic module.
Save this file as tags_gen.sh and do chmod a+rx tags_gen.sh.
<code>
#!/bin/sh
tmp_tag=tags_file
tmp_tag2=tags_file2
echo " "
echo " "
echo " "
echo " "
echo " "
echo "Generate tags for ...."
while :
do
echo " Enter file extension for which you want to generate tags."
echo -n " File-extension should be like sh, js, ksh, etc... : "
read ans
if [ "$ans" == "" ]; then
echo " "
echo "Wrong entry. Try again!"
else
break
fi
done
\rm -f $tmp_tag
aa=`ls *.$ans`
for ii in $aa
do
jj=`echo $ii | cut -d'.' -f1`
#echo $jj
cp $ii $jj.c
ctags $jj.c
echo "s/$jj.c/$ii/g" > $tmp_tag2
sed -f $tmp_tag2 tags >> $tmp_tag
\rm -f tags $jj.c
done
sort $tmp_tag > tags
\rm -f $tmp_tag $tmp_tag2
</code>
<sect1> Debugger gdb
<p>
You would be using gdb extensively along with Vi.
Debugging is the most important aspect of programming
as the major cost of software projects goes into debugging and testing.
<p>
To debug C++/C programs use 'gdb' tool. See <bf>'man gdb'</bf>.
You must compile your programs with -g3 option like
<tscreen><verb>
gcc -g3 foo.c foo_another.c sample.c
</verb></tscreen>
To set up easy aliases do -
<tscreen><verb>
Setup an alias in your ~/.bash_profile
alias gdb='gdb -directory=/home/src -directory=/usr/myname/src '
Give -
gdb foo.cpp
gdb> dir /hom2/another_src
This will add to file search path
gdb> break 'some_class::func<TAB><TAB>
This will complete the function name saving you typing time... and will output like -
gdb> break 'some_class::function_foo_some_where(int aa, float bb)'
</verb></tscreen>
Pressing TAB key twice is the command line completion, which will save
you lots of typing time. This is one of the most important technique of using gdb.
To get online help do -
<tscreen><verb>
gdb> help
Gives online help
gdb> help breakpoints
Gives more details about breakpoints.
</verb></tscreen>
To set breakpoints and do debugging
<tscreen><verb>
unixprompt> gdb exe_filename
gdb> b main
This will put breakpoint in main() function
gdb> b 123
This will put breakpoint in line 123 of the current file
gdb> help breakpoints
Gives more details about breakpoints.
</verb></tscreen>
To analyze the core dumps do
<tscreen><verb>
unixprompt> gdb exe_filename core
gdb> bt
Gives backtrace of functions and line numbers where the program failed
gdb> help backtrace
Gives more details about backtrace.
</verb></tscreen>
<p>
You can also use GUI version of gdb called xxgdb.

<sect> Vi Tutorial <label id="vimtut">
<p>
In this tutorial, we describe some "advanced" <bf>vi</bf> concepts and commands, so you can appreciate the power of <bf>vi</bf> and so you decide how to build your
knowledge of <bf>vi</bf> commands. Nearly all <bf>vi</bf> references list the available
commands, but many don't bother to discuss how the commands interrelate;
this topic is the main purpose of this tutorial.
<sect1> Cursor Movement Commands
<p>
The <bf>vi</bf> cursor movement commands allow you to position the cursor in the file
and/or on the screen efficiently, with a minimum number of keystrokes. There
are oodles of cursor movement commands - don't try memorizing them all at
once! Later, we'll see that much of the power of <bf>vi</bf> comes from mixing cursor
movement commands with other commands to delete, change, yank (copy), and
filter text.
Please edit a large text file (say, <bf>wknight</bf>) so you can experiment with each
command as it is described. Keep in mind these commands will only work in
Command Mode, not Insert Mode; if you start getting your "commands" in your
text, press the ESC key to return to Command Mode.
<itemize>
<item> <bf>cursor keys</bf> : As we've seen, cursor keys move by single character amounts
left, down, up, and right. Movement above the top of the file,
below the bottom, to the right of the end of a line, or left of the
beginning is not allowed (no line wrapping).
<p>
<item> <bf>hjkl</bf> : When <bf>vi</bf> was written (around 1978), many terminals on UNIX
systems did not have cursor keys! <bf>h, j, k,</bf> and <bf>l</bf> were chosen
as commands to move left, down, up, and right, respectively.
Try them! Most <bf>vi</bf> diehards prefer these to the cursor keys
because
<itemize>
<item><bf>(a)</bf> they are in the same place on all keyborads, and
<item><bf>(b)</bf> they fit nicely under the fingers, unlike
most cursor keys, which are arranged in a box or "T" or some
other nonlinear shape.
</itemize>
Why h, j, k, and l? Well, in the ASCII character set, CTRL-H is backspace
(moves left), CTRL-J is linefeed (moves down), and, of course, k and l are
next to h and j, so you see, they're mnemonic.
<p>
<item> <bf>0</bf> : ("zero", not "oh") Move to the beginning of current line. (To try
this and the next few commands, use the cursor keys or <bf>h j k l</bf> to
move to an indented text line that contains few "e"
characters. If you can't find an indented line in your file, create
one by inserting a few space characters at the beginning of a
line.)
<p>
<item> <bf> ^ </bf> : Move to first non-white character of current line. (For
indented line, 0 and ^ are different.)
<p>
<item> <bf> $ </bf> : Move to last character of current line.
<p>
<item> <bf> tC </bf> : Move to (but not on) next character c in current line. (Press 0,
then press te. This will move to the first e in the curent line.)
<p>
<item> <bf> fC </bf> : Find (move on top of) next character c in current line. (Press
fe, and the cursor will find - that is, move on top - the next e in
the current line.)
<p>
<item> <bf> TC </bf> : Move to (but not on) the previous character c in current line
(Press $, then Te.)
<p>
<item> <bf> FC </bf> : Find (move on top of) the previous character c in current line.
(Press Fe.)
<p>
<item> <bf> n| </bf> : Move to column n in current line. (Try 20 |. The digits 2 and 0
will not be displayed as you type them, but when you press | the cursor will
move to column 20.)
Try some experiments with t f T F | . When you do something illegal, <bf>vi</bf> will
beep your terminal.
<p>
<item> <bf> w </bf> : Forward to beginning of next "small" word ( a "small" word
consists of unbroken alphanumeric characters or punctuation characters, but
not mixed alphanumeric and punctuation). Try
tapping w a dozen times or so - note what happens at
punctuation.
<p>
<item> <bf> W </bf> : Forward to beginning of next "big" word (alphanumeric and
punctuation mixed). Try W a dozen times or so.
<p>
<item> <bf> b </bf> : Backward to beginning of "small" word.
<p>
<item> <bf> B </bf> : Backward to beginning of "big" word.
<p>
<item> <bf> e </bf> : Forward to end of "small" word.
<p>
<item> <bf> E </bf> : Forward to end of "big" word.
<p>
<item> <bf> + Return </bf> : Move to first non-white space character on next line. (+ and
the Return key have the same effect.)
<p>
<item> <bf> - </bf> : Move to first non-white space character on previous line.
<p>
<item> <bf> ) </bf> : Move to the end of sentence. (A sentence ends either at a
blank line or at a period or examination mark followed by two
space characters or at the end of a line. A period or
exclamation mark followed by one space character does not
end a sentence; this is correct behaviour, according to traditional
rules of how sentences should appear in typed documents, but often
appears wrong to those who have never suffered through
a formal typing class.)
<p>
<item> <bf> ( </bf> : Move to beginning of sentence.
<p>
<item> <bf> } </bf> : Move to end of paragraph. (Paragraphs are seperated with
blank lines, by <bf>vi</bf>'s definition.)
<p>
<item> <bf> { </bf> : Move to beginning of paragraph.
<p>
<item> <bf> H </bf> : Move to home position (top line) on the screen
<p>
<item> <bf> M </bf> : Move to middle line on the screen.
<p>
<item> <bf> L </bf> : Move to last line on the screen.
<p>
<item> <bf> nG </bf> : Move to line n. If n is not given, move
to the last line in the file.
(Try 15G to move to line 15, for example. The CTRL-G command displays
the name of the file, some status information, and the
current line number. To move to the top of the file: 1G)
<p>
<item> <bf> CTRL-d </bf> : Scroll down half-screen (see note).
<item> <bf> CTRL-u </bf> : Scroll up half-screen (see note).
<item> <bf> CTRL-f </bf> : Move forward one-screen (see note).
<item> <bf> CTRL-b </bf> : Move backward one-screen (see note).
<item> <bf> Note </bf> : These four scrolling/paging commands cannot be used
with the delete, change, yank, or filter commands.
<p>
<item> <bf> /reg_exp </bf> : Move to next occurrence of the regular expression reg_exp
When you press /, the cursor drops to the lower left corner of the screen and
waits for you to type in the regular expression.
Press the Return key to finish; <bf>vi</bf> then searches forward for the next
occurrence of the regular expression. For example, press /the followed by
Return. This moves forward to the next occurrence of the, perhaps imbedded
in the middle of some longer word (other, weather, etc.). If you just press /
and then Return, <bf>vi</bf> searches for the next occurrence of whatever the last
regular expression was that you searched for.
<p>
<item> <bf> n </bf> : Has the same effect as pressing / and then Return; i.e.,
searches for the next occurrence of whatever the last regular
expression was that you searched for.
<p>
<item> <bf> ?reg_exp </bf> : Searches backward, rather than forward. If no reg_exp is
given, it searches for the last regular expression that was entered.
Both / and ? wrap around, so searching "below" the bottom or "above" the
top of the file is legal.
<p>
<item> <bf> N </bf> : Same as pressing ? and then Return.
</itemize>
<sect1> Repeat Counts
<p>
Many of the movement commands discussed above can be preceded with a
repeat count; the movement is simply repeated the given number of times:
<itemize>
<item> <bf> 3w </bf> : Move forward three words
<item> <bf> 5k </bf> : Move up four characters
<item> <bf> 3fa </bf> : Find the third succeeding a in current line
<item> <bf> 6+ </bf> : Move down six lines
</itemize>
For some commands, the "repeat counts" has special meaning:
<itemize>
<item> <bf> 4H </bf> : Move to Line 4 on the screen (home plus 3)
<item> <bf> 8L </bf> : Move to the eigth line from the bottom of the screen
<item> <bf> 3$ </bf> : Move to the end of the third line down
</itemize>
For some commands (e.g., ^) the repeat count is ignored; for others (e.g.,
/ and ? ) it is illegal
<sect1> Deleting Text
<p>
We've seen that <bf>dd</bf> deletes the current line. This can be used
with a repeat
count: 3dd deletes three lines, the current line, and the two following lines.
The d command can be used as a "prefix" on most of the movement commands
above to delete nearly arbitrary chunks of text. When used with d, the
movement commands are called target specifiers. d can be given a repeat
count. (As you try these experiments, remember to press u after each command
to undo the deletion).
<itemize>
<item> <bf> dw </bf> : Delete "small" word forward
<item> <bf> d3w </bf> : Delete three "small" words forward
<item> <bf> 3dw </bf> : Three times, delete "small" word forward
<item> <bf> 3d3w </bf> : Three times, delete three "small" words forward (that is,
delete nine "small" words forward)
<item> <bf> d+ </bf> : Delete current line and next line down
<item> <bf> d/the </bf>: Delete from current character up to but not including the
next occurrence of the pattern the.
<item> <bf> d$ </bf> : Delete to end of line
<item> <bf> d0 </bf> : Delete to beginning of line
<item> <bf> d30G </bf> : Delete from the curent line to and including Line 30
<item> <bf> dG </bf> : Delete from current line to and including last line
<item> <bf> d1G </bf> : Delete from current line to and including Line 1
</itemize>
To delete single characters, use x. x can be given a repeat count:
<itemize>
<item> <bf> 15x </bf> : Delete current and 14 following characters
</itemize>
x is actually just an abbreviation of d1; that is, delete one character right.
<sect1> Changing Text
<p>
The c command is similar to d, except it toggles <bf>vi</bf> into Insert Mode, allowing
the original (unwanted) text to be changed to something else.
For example, put the cursor on the beginning of a word (press w to get to the
beginning of the next word). Then, press cw to change that word. On the
screen, the last character in the word being changed will be replaced
with a <bf>$</bf>
symbol indicating the boundary of the change; type in a new word (you will
overwrite the original word on the screen) and press the ESC key when done.
Your input may be longer or shorter than the word being changed.
Put the cursor at the beginning of a line containing at least three words, and
try c3w to change three words. Try c$ to change to the end of the current line.
In all cases where the change affects only the current line, the boundary of the
change is indicated with $.
When a change affects more than just the current line, <bf>vi</bf> deletes the original
text from the screen and toggles into Insert Mode. For example, try c3+ to
change the current and the next three lines; <bf>vi</bf> deletes the four
original lines from the screen and toggles into Insert Mode in a new blank line.
As usual, press the ESC key when you have finished entering your new text.
Some other change commands:
<itemize>
<item> <bf> cc </bf> : Change current line
<item> <bf> 5cc </bf> : Change five lines (current and next four)
<item> <bf> c/the </bf> : Change from current character up to but not including the next
occurrence of the pattern the
<item> <bf> c$ </bf> : Change to end of line
<item> <bf> c30G </bf> : Change from the current line to and including Line 30
<item> <bf> cG </bf> : Change from curernt line to and including last line
<item> <bf> c1G </bf> : Change from curernt line to and including Line 1
</itemize>
<sect1> Yanking (Copying) Text
<p>
The y command yanks a copy of text into a buffer; the yanked text can then
be put (or pasted) elsewhere in the file using p or P.
The simplest form of yank is yy to yank the current line; after yy, try p to
put a copy of the yanked line after the cursor. Following yy, you can make
as many copies of the yanked line as you want by moving up and down in the file
and pressing p.
To copy multiple lines, try, for example, 5yy (yank the current and next four
lines). p puts a copy of the yanked lines after the cursor; the sequence 5yyp
"works" but it probably doesn't do what you would like. The P command is like
p, but puts a copy of the yanked text ahead of the cursor; try the sequence
5yyP.
Other yank commands:
<itemize>
<item> <bf> y3w </bf> : Yank three words
<item> <bf> y$ </bf> : Yank to end of current line
<item> <bf> y1G </bf> : Yank from current line to and including Line 1
</itemize>
<sect1> Filtering text
<p>
The filter command <bf>!</bf>, prompts for the name of a UNIX command (which should
be a filter), then passes selected lines through the filter, replacing those
selected line in the <bf>vi</bf> buffer with the output of the filter command. <bf>vi</bf>'s
ability to pass nearly arbitrary chunks of text through any UNIX filter adds
incredible flexibility to <bf>vi</bf>, at no "additional cost" in size or performance to
<bf>vi</bf> itself.
Some examples will help illustrate. Create a line in your file containing just
the word who and absolutely no other text. Put the cursor on this line, and press <bf>!!</bf>
This command is analogous to dd, cc, or yy, but instead of deleting, changing,
or yanking the current line, it filters the current line. When you press the
second !, the cursor drops down to the lower left corner of the screen and a
single ! is displayed, prompting you to enter the name of a filter. As the
filter name, type sh and press the Return key. <bf>sh</bf> (the Bourne shell) is a filter!
It reads standard input, does some processing of its input (that is, executes
commands), and sends its output (the output of those commands) to standard output. Filtering the line containing who through sh causes the line containing who to be replaced with a list of the current users on the system - right in your file!
Try repeating this process with <bf>date</bf>. That is, create a line containing nothing
but the word <bf>date</bf>, then put the cursor on the line, and press <bf>!!sh</bf> and the
Return key. The line containing <bf>date</bf> is replaced with the output of the <bf>date</bf>
command.
Put your cursor on the first line of the output of who. Count the number of lines.
Suppose, for example, the number is six. Then select those six lines to be
filtered through sort; press <bf>6!!sort</bf> and the Return key. The six lines will
be passed through sort, and sort's output replaces the original six lines.
The filter command can only be used on complete lines, not on characters or
words.
Some other filter commands (here, &lt CR &gt means press Return):
<itemize>
<item> <bf>!/the &lt CR &gt sort &lt CR &gt</bf> : Sort from the current line up to and including the
next line containing the
<item><bf> !1Ggrep the &lt CR &gt</bf> : Replace from the current line to and including Line 1
with just the lines that contain the
<item><bf> !Gawk '{print $1}' &lt CR &gt </bf>: From the current line to the end of file, replace every line with just its first word.
</itemize>
<sect1> Marking Lines and Characters
<p>
You can mark lines and characters to be used as targest for movement, deletion,
change, yanking, and filtering using the command mc, where c is a
lowercase letter.
For example, put the cursor in the middle of some word and press ma. This
marks the character under the cursor as mark a.
Now, move the cursor off the marked character and to a different line ( use
the cursor keys, CTRL-u, or whatever). To return to the marked line, press 'a
(that is, single quote, then a). This moves to the first non-white space
character on the line containing mark a.
Move off that line again. To return to the marked character, press `a (that is,
backquote, then a). This moves on top of the character marked with a.
Marking is usually used with deleting, changing, yanking or filtering. For
example, move the cursor to a line other than the one containing mark a,
and then press d'a (d, single quote, a). This deletes from the current line to and
including the line marked with a.
Put the cursor in the middle of a different word and press mb to set mark b.
Now, move the cursor away from that word (but only a few lines, so you can see
what we're about to do more easily), and then press d`b (d, backquote, b).
This deletes from the current CHARACTER to and including the CHARACTER marked
with b.
As another example, to sort the output of who, mark the first line (ma), then
move the cursor to the last line and press !'asort and the Return key.
If you jump to a mark and decide you want to jump back to whatever you jumped
from, you can press '' (jump back to line) or `` (jump back to character).
<sect1> Naming Buffers
<p>
When you delete, change, or yank text, the original text is stored (until the next delete, change, or yank) in an unnamed buffer from which it can be put using
p or P. Using the unnamed buffer, only the most recently deleted, changed or yanked
text may be recovered.
If you wish to delete, change, or yank multiple sections of text and remember
them all (up to a maximum of 26), you can give a buffer name ahead of the
delete change or yank command. A buffer name has the form "c (double quote,
lowercase c).
For example, press "ayy to yank the current line into buffer a, then move to a
different line and press "byy to yank that line into buffer b. Now, move
elsewhere in the file and press "ap and "bp to put copies of the text
stored in buffers a and b.
Some other named buffer commands:
<itemize>
<item> <bf> "a6yy </bf> : Yank six lines (current and next five) into buffer a
<item> <bf> "bd1G </bf> : Delete from the curernt line to and including Line 1,
storing the deleted lines in buffer b
<item> <bf> "cy'c </bf> : Yank from the current line to the line marked c into buffer c
(marks and buffers are distinct, and may
have the same name without confusing <bf>vi</bf>)
</itemize>
<sect1> Substitutions
<p>
To substitute one chunk of text for another in lines throughout your file,
use the :s command. Some substitute examples:
<itemize>
<item> <bf> :1,$s/the/THE/g </bf> From Line 1 to the last line (line $), substitute
for the text THE; do this globally in each line where the occurrs
<item> <bf> :'a,.s/.*/ha ha/ </bf> From the line marked a to the current line (line .),
substitute for everything on the line the text ha ha
</itemize>
<sect1> Miscellaneous "Colon Commands"
<p>
All colon commands begin with a colon; when you press the colon, the cursor
drops to the lower left corner of the screen, and a colon prompt is displayed
waiting for you to finish your colon command.
Some important examples:
<itemize>
<item><bf>:w </bf> Write the buffer contents to the file without quitting from <bf>vi</bf>
<item><bf>:w abc </bf>Write the buffer contents to the file abc (creating abc
if it doesn't exist, or overwriting current contents if it does exist) without
quitting from <bf>vi</bf>
<item><bf>:1,10w abc </bf>Write lines 1 through 10 to file abc
<item><bf>:'a,$w abc </bf>Write from the line marked a to the last line into file abc
<item><bf>:e abc </bf>Edit file abc, instead of the current file. <bf>vi</bf> prints an error
message if changes have been made to the curernt file that have not been saved
with :w
<item><bf>:e! abc </bf>Edit file abc, throwing away any changes that may
have been made to the current file
<item><bf>:e # </bf>Edit the prior file edited (successive :e# commands toggle
back and forth between two files)
<item><bf>:f abc </bf>Change the file anme for the current <bf>vi</bf> buffer to abc
<item><bf>:q </bf>Quit, unless unsaved chanegs have been made
<item><bf>:q! </bf>Quit, throwing away any changes that may have been made
<item><bf>:r abc </bf>Read the file abc into current <bf>vi</bf> buffer, after the line the
cursor is on (try :r croc to read in a copy of the croc file)
<item><bf>:!cmd </bf>Execute command cmd (who, sort, ls, etc.)
</itemize>
<sect1> Setting Options
<p>
Various options affect the "feel" of <bf>vi</bf>. You can display all the various options
that can be set using the colon command :set all. You can also use set to
change options.
For example, if you want to see line numbers for the lines in the file you're
editing, use the command :set number. To turn off line numbering, use
the command :set nonumber. Most options can be abbreviated; :set nu turns
on line numbering and :set nonu turns off line numbering.
If you :set nomagic, the special meanings of regular expression characters
(period, asterisk, square bracket, etc.) are switched off. Use :set magic to
restore the special meanings.
Some options take a value. For example, :set tabstop=4 causes tabs to
be displayed as four space characters, rather than the usual eight.
If you find you always want certain options set certain ways, you can put the
set commands you want ina file .exrc, or you can set up the
environment variable EXINIT to specify the options you want.
For example, if your login shell is Bourne shell, this line could go in your
.profile file:
<code>
EXINIT='set nomagic nu tabstop=4'; export EXINIT
</code>
If your login shell is a C shell, this line could go in your .login file:
<code>
setenv EXINIT 'set nomagic nu tabstop=4'
</code>
<sect1> Key Mappings
<p>
If you find you're performing a series of simple commands over and over,
you can map the command series to an unused command key using the :map
command. If your mapping must include control characters such as Return
key (CTRL-M in ASCII) or the ESC (CTRL-[ in ASCII) key, precede such
characters with CTRL-v to suppress their usual special meaning.
For example, this command maps CTRL-A to move the cursor forward 55 lines,
then back up to the most recent blank line, then change that blank line
to a formfeed (CTRL-L) and three blank lines. That is, each CTRL-A will
paginate the next page, without splitting paragraphs across pages.
Note: In this command, each control character is shown as ^C, where C is
some uppercase letter. For example, CTRL-M is shown as ^M. Also, when you enter
this command you will not see the CTRL-v characters as shown: each CTRL-v
merely suppresses the usual special meaning of the following control
character, so when you press the sequence ^V^M, all you will see on the screen is
^M. In this command, ^M is the Return key and ^[ is the ESC key.
<code>
:map ^A 55+?^$^V^Mcc^V^L^V^M^V^M^V^M^V^[
</code>
<sect1> Editing Multiple Files
<p>
You can edit multiple files with <bf>vi</bf> by giving multiple file names as command
line arguments:
<code>
vi croc fatherw wknight
</code>
Three colon commands are used to move through the multiple files:
<itemize>
<item><bf> :n </bf>Move to the next file in the argument list (you must save
changes with :w or <bf>vi</bf> will print an error message)
<item><bf> :N </bf>Move to the previous file in the argument list (you must save
changes with :w or <bf>vi</bf> will print an error message)
<item><bf> :rew </bf>Rewind and start over with the first file in the argument list
</itemize>
The :n, :N, and :rew commands are somewhat clumsy, but there are some
important benefits: the contents of named buffers ("a, "b, "c, etc.) are
remembered across files, so you can use :n and :rew with p and P to copy
text back and forth between files. Also, the most recent search string for the
/ and ? commands remembered across files, so you can do repetitive searches
in multiple files rather easily.
For example, try the following experiment:
First get out of <bf>vi</bf>, then execute <bf>vi</bf> with croc and wknight as arguments:
<code>
$ vi croc wknight
</code>
In croc, search for the
<bf> /the &lt CR &gt </bf>
Yank this line into buffer a:
<bf> "ayy </bf>
Now go to the next file (you've made no change to croc, so this will work):
<bf> :n &lt CR &gt </bf>
Search for the "next" line containing the, without retyping the search string:
<bf> n </bf>
Put a copy of buffer a after the current line in wknight:
<bf> "ap </bf>
Move down two lines, and yank the current line into buffer b:
<bf> jj"byy </bf>
Save the changes to wknight
<bf> :w &lt CR &gt </bf>
Now, rewind to croc
<bf> :rew &lt CR &gt </bf>
Search again, and put a copy of buffer b after the found line:
<bf> n"bp </bf>
Save the changes, and exit <bf>vi</bf>
<bf> ZZ </bf>
<sect1> Final Remarks
<p>
This tutorial was intended to introduce some of the <bf>vi</bf> capabilities that you
might overlook in your system's <bf>vi</bf> manual or that might not be mentioned in
the manual (different systems have manuals of widely varying quality).
You will not be a <bf>vi</bf> expert after reading this tutorial, but you will have a
good appreciation of <bf>vi</bf>'s capabilities. Only time and effort can make a <bf>vi</bf>
expert. But the efficiency and universality of <bf>vi</bf> make this effort pay off in
the long run.
You may have decided you hate <bf>vi</bf>. So be it! But be aware that <bf>vi</bf> remains
the standard UNIX text editor - the one editor you can count on being
available on every UNIX system you'll use - so even if you prefer to use
something else day-to-day, you'd be well advised to know the bare minimum <bf>vi</bf>
material covered in this tutorial.

<sect> Build Your "WYSIWYG" HTML Editor With Vi & Netscape
<p>
This section was written by
<url url="http://www.pcquest.com/content/linux/handson/101100102.asp" name="Manas K Laha">
, Aerospace Engineering Department, IIT Kharagpur, India.
This is about a quick and dirty way to create an HTML editor combining vi and Netscape.
If vi (or one of its friends, such as elvis or vim ) is your favorite text
editor, as it is mine, you must surely long for a way
of creating HTML with it quickly and comfortably. And
if with that you could get the convenience of
"WYSIWYG", wouldn't you just jump at it? All this is
indeed possible, and here we'll see how.
The major hurdles I've found in editing HTML with vi are
<enum>
<item> The need to write HTML tags. It appears that there
are more tags to be written than displayable matter. Moreover, some
of these tags have a syntax that is hard to remember.
<item> The need to keep track of whether an opening tag has been given
its proper closing tag at the right place (for example, whether a <
ol> has a
matching <
/ol> ).
<item> Difficulty in readily identifying matching pairs of tags.
</enum>
These can be got around using some of the less used features of vi and
friends. In this article I shall use vim for definiteness, but the ideas should
apply to classic vi and its other look-alikes as well.
The "abbreviation" feature of vim:
Vim has a feature whereby it is possible to assign a keystroke sequence to
represent a string of characters in input mode. This is the ab colon
command. For example, the command
<code>
:ab tT &lt
tt> &lt
/tt>
</code>
creates an abbreviation, named tT, for the sequence of characters <
tt><
/tt>.
Then, in input mode, as soon as the characters tT are typed, they are
replaced by the string <
tt><
/tt>. Complicated HTML tags may also be
abbreviated. The ab definition
<code>
:ab aH <a href=?http://?><!? { ?>^M
Comments here^M^D &lt
/a><!? } ?>
</code>
makes aH the shorthand for
<code>
<a href=?http://?><!? { ?>
Comments here
&lt
/a><!? } ?>
</code>
where the two ^M s cause the two line breaks and the ^D causes the closing
<
/a> tag to be indented back to be in line with the opening <
a> tag.
(Indenting the matter enclosed within a matching pair of tags makes reading and
editing the raw HTML easier.) The syntax of the tag is outlined, as an aid to
memory. The 'Comments here' line is a placeholder, to be replaced with
appropriate text.
What are the { and } within HTML comments doing there? Aha! Those are for
matching the opening and closing tags (in this case <
a> and <
/a>). The bracket
matching feature of vi (using the % key) is readily usable for the purpose. This
can be really helpful when the opening and closing tags are many lines apart
and cannot be readily matched 'by eye', such as can be the case with the
<
ol><
/ol> pair.
This technique can be extended to generate fancier HTML, for example with
frames. All one has to do is to define the appropriate abbreviations. For
example, the definition
<code>
:ab fS &lt
frameset scrolling=?no?
frameborder=?0? framespacing=?0?
cols=?20%,80%?>&lt
!? { ?>^M &lt
/frameset> &lt
!?
} ?>
</code>
makes the string fS a convenient
abbreviation for the pair of tags:
<code>
&lt
frameset scrolling=?no? frameborder=?0?
framespacing=?0? cols=?20%,80%?> &lt
!? { ?>
&lt
/frameset>&lt
!? } ?>
</code>
Some tags do not like comments to come in between the opening and closing pair.
The ones I have found are <
title><
/title> and <
a\ href=?mailto:?>
<
/a>. Luckily, in both these the opening and closing pair are never very far
apart, so the braces-within-comments feature is not needed.
<sect1>
Sample .vimhtmlrc File
<p>
How do I tell vim about these abbreviations? I put all of them (and a
command to set some of vim's variables) in a file, which I call .vimhtmlrc and
which resides in my home directory, and invoke
<code>
vim -u ~/.vimhtmlrc index.html
</code>
where index.html is the HTML file I want to edit. This is what my .vimhtmlrc
file looks like:
<code>
ab aH &lt
a href=?http://?>&lt
!? { ?>^M
Comments here^M^D&lt
/a> &lt
!? } ?>
ab aM &lt
a href=?mailto:?>^M Comments

</code>
When the ab commands are put in a file, to be read in by vim at startup, then
the leading :is not needed. The last line is a command to set some of vim 's
variables. Here is what they mean:
<code>
se set: tells vim to activate the options that follow autoindent: begin the next
ai line in the same column as this one (and not from column 1)
aw autowrite: automatically write file to disk when it changes on a TAB key, move cursor 4
ts=4 characters (and not the normal 8); this is my personal preference
sw=4 number of spaces to use for indentation chars from right margin where
wm=10 line wrapping starts (useful if one is writing running text and not programs)
message on status line to show
showmode current mode (for the novice, actually) briefly jump to matching
opening '(' or '{' or '[' as
showmatch soon as a closing ')' or '}' or ']' is typed; beep if no match
ruler show cursor line and column in status line some characters, such as '.'
magic and '*', have special meanings in search and replace patterns.
</code>
Typing help in a vim window shows the explanations for these options and many
more besides.
<sect1>
WYSIWYG
<p>
'WYSIWYG' has two parts to it. To begin with is the fact that Netscape under
Unix (and Linux) can be controlled remotely.
That is, you may control the behavior of an already running Netscape through
commands of the form
<code>
netscape -remote -noraise 'openFile(/home/mlaha/html/index.html)'
</code>
(If no Netscape is running, the command just exits with an error message.) This
command causes the Netscape browser window to attempt to open the file
/home/mlaha/html/index.html. For more on remote controlling Netscape, see
<url url="http://home.netscape.com/newsref/std/x-remote.html">.
And then, there is atchange . Jeffrey Copeland and Jeffrey Haemer
(<url url="http://alumni.caltech.edu/~copeland/work/edit-web.html"> ,
<url url="ftp://ftp.ncifcrf.gov/pub/delila/atchange">
and <url url="http://www.lecb.ncifcrf.gov/~toms/atchange.html"> )
describe a little shell script, called atchange, that waits in the
background for a named file to change and then invokes a specified command. Thus,
<code>
atchange index.html 'netscape -noraise -remote 'openFile(/home/mlaha/html/index.html)'' &
</code>
would cause atchange to run in the background, watching the file index.html
and, as soon as it changed, ask Netscape to display it afresh. If you were
editing index.html with vi, then, when you saved it (with :w, say), atchange
would spring into action and Netscape would update its display.
If you wish to edit another HTML file, you have to quit vim, kill the current
invocation of atchange, then start it again with the name of the new file in
place of index.html and begin editing that file with vim.
<sect1>
Other 'WYSIWYG' uses
<p>
As you may have guessed, atchange can be used in other instances, too. You can
make a handy 'WYSIWYG' LaTeX editor by having atchange monitor your LaTeX
source and, when it changed, run the necessary programs to convert it to
Postscript. The 'WYSIWYG' capability is provided in this case by invoking
Ghostview with the monitoring option (-watch) that causes it to redisplay its
current Postscript file whenever that file changes. Thus, every time you saved
your LaTeX source file in the editor, the Postscript output with the latest
changes would be automatically displayed in the Ghostscript window.

# who wrote the original version as a shell script
# version = 2.07 of atchange 1999 Dec 30
# 1999 Dec 18: Added shell call to /bin/csh so that
# atchange works under Linux.
# 1999 Feb 5: By setting the PERLCSH variable, the new shell can tell

# The test inside the .cshrc is:
#if ( (! $?PERLCSH ) && $?prompt) then
# stty erase '^H'
# set prompt = "`uname -n` \!% "
#endif
# This is necessary under Sun Solaris 2.6 because otherwise the
# call to stty gives an error message now.

<p>
PDF file can be generated from postscript file using
either acrobat <bf>distill</bf> or <bf>Ghostscript</bf>.
And postscript file is generated
from DVI which in turn is generated from LaTex file.
You can download distill software from <url url="http://www.adobe.com">. Given below
is a sample session:
<code>
bash$ man sgml2latex
bash$ sgml2latex filename.sgml
bash$ man dvips
bash$ dvips -o filename.ps filename.dvi
bash$ distill filename.ps
bash$ man ghostscript
bash$ man ps2pdf
bash$ ps2pdf input.ps output.pdf
bash$ acroread output.pdf &
</code>
Or you can use Ghostscript command <bf>ps2pdf</bf>.
ps2pdf is a work-alike for nearly all the functionality of
Adobe's Acrobat Distiller product: it
converts PostScript files to Portable Document Format (PDF) files.
<bf>ps2pdf</bf> is implemented as a very small command script
(batch file) that invokes Ghostscript, selecting a special "output device"
called <bf>pdfwrite</bf>. In order to use ps2pdf, the pdfwrite
device must be included in the makefile when Ghostscript was compiled;
see the documentation on building Ghostscript for details.

The linuxdoc is very simple and is easy to use. To convert linuxdoc SGML
file to Docbook SGML use the program <bf>ld2db.sh</bf> and some perl scripts.
The ld2db output is not 100% clean and you need to use the <bf>clean_ld2db.pl</bf>
perl script. You may need to manually correct few lines in the document.
<itemize>
<item> Download ld2db program from <url url="http://www.dcs.gla.ac.uk/~rrt/docbook.html">
or from <url name="Al Dev site" url="http://www.milkywaygalaxy.freeservers.com">
<item> Download the cleanup_ld2db.pl perl script from
from <url name="Al Dev site" url="http://www.milkywaygalaxy.freeservers.com">
</itemize>
The ld2db.sh is not 100% clean, you will get lots of errors when you run
<code>
bash$ ld2db.sh file-linuxdoc.sgml db.sgml
bash$ cleanup.pl db.sgml > db_clean.sgml
bash$ gvim db_clean.sgml
bash$ docbook2html db.sgml
</code>
And you may have to manually edit some of the minor errors after
running the perl script. For e.g. you may need to put closing tag <
/Para> for each <

You can convert the SGML howto document to Microsoft Windows Help file,
first convert the sgml to html using:
<code>
bash$ sgml2html xxxxhowto.sgml (to generate html file)
bash$ sgml2html -split 0 xxxxhowto.sgml (to generate a single page html file)
</code>
Then use the tool <url name="HtmlToHlp" url="http://javadocs.planetmirror.com/htmltohlpe.html">.
