% The final reference card has six columns, three on each side.
% This file can be used to produce it in any of three ways:
% 1 column per page
%    produces six separate pages, each of which needs to be reduced to 80%.
%    This gives the best resolution.
% 2 columns per page
%    produces three already-reduced pages.
%    You will still need to cut and paste.
% 3 columns per page
%    produces two pages which must be printed sideways to make a
%    ready-to-use 8.5 x 11 inch reference card.
%    For this you need a dvi device driver that can print sideways.
% Which mode to use is controlled by setting \columnsperpage above.

\section{Loading Viper}

Just type \kbd{M-x viper-mode} followed by \kbd{RET}

OR put

(setq viper-mode t)
(require 'viper)

in .emacs

\section{Viper States}

Viper has four states: {\it emacs state}, {\it vi state}, {\it insert state},
{\it replace state}.
Mode line tells you which state you are in.
In emacs state you can do all the normal GNU Emacs editing.
This card explains only vi state and insert state (replace state is similar
to insert state).
{\bf GNU Emacs Reference Card} explains emacs state.
You can switch states as follows.

\key{from emacs state to vi state}{C-z}
\key{from vi state to emacs state}{C-z}
\key{from vi state to emacs state for 1 command}{$\backslash$}
\metax{from vi state to insert state}{i, I, a, A, o, O}
\metax{from vi state to replace state}{c, C, R}
\key{from insert or replace state to vi state}{ESC}
\key{from insert state to vi state for 1 command}{C-z}


\section{Insert Mode}
You can do editing in insert state.

\metax{go back to vi state}{ESC}
\metax{delete previous character}{C-h, DEL}
\key{delete previous word}{C-w}
\key{delete line word}{C-u}
\key{indent shiftwidth forward}{C-t}
\key{indent shiftwidth backward}{C-d}
\key{delete line word}{C-u}
\key{quote following character}{C-v}
\key{emulate Meta key in emacs state}{C-$\backslash$}
\key{escape to Vi state for one command}{C-z}

\vskip 2mm

{\bf The rest of this card explains commands in {\bf vi state}.}

\section{Getting Information on Viper}

Execute info command by typing \kbd{M-x info} and select menu item
\kbd{viper}.  Also:

\key{describe function attached to the key {\it x}}{$\backslash$ C-h k {\it x}}

\section{Leaving Emacs}

\metax{suspend Emacs}{:st {\rm or} :su}
\metax{exit Emacs permanently}{C-xC-c}
\metax{exit current file}{:wq {\rm or} :q}

\shortcopyrightnotice

\section{Error Recovery}

\metax{abort command}{C-c (user level = 1)}
\metax{abort command}{C-g (user level > 1)}
\key{redraw messed up screen}{C-l}
\metax{{\bf recover} after system crash}{:rec file}
\metax{restore a buffer }{:e!\ {\rm or} M-x revert-buffer}


\section{Counts}

Most commands in vi state accept a {\it count} which can be supplied as a
prefix to the commands.  In most cases, if a count is given, the
command is executed that many times.  E.g., \kbd{5 d d} deletes 5
lines.

\section{Registers}

There are 26 registers (\kbd{a} to \kbd{z}) that can store texts
and marks.
You can append a text at the end of a register (say \kbd{x}) by
specifying the register name in capital letter (say \kbd{X}).
There are also 9 read only registers (\kbd{1} to \kbd{9}) that store
up to 9 previous changes.
We will use {\it x\/} to denote a register.
\section{Entering Insert Mode}

\key{{\bf insert} before first non-white}{I}

\key{move cursor to {\bf next} window}{C-x o}
\key{delete current window}{C-x 0}
\key{delete other windows}{C-x 1}
\key{split current window into two windows}{C-x 2}
\key{{\bf switch} to a buffer in the current window}{C-x {\sl buffer}}

\key{{\bf overwrite} {\it n} lines}{{\it n} R}

\metax{{\bf buffer} search (if enabled)}{g {\it move command}}

\section{Modifying Commands}

Most commands that operate on text regions accept the motion commands,
to describe regions. They also accept the Emacs region specifications
{\bf r} and {\bf R}. {\bf r} describes the region between {\it point}
and {\it mark}, and {\bf R} describes whole lines in that region.
Motion commands are classified into {\it point commands} and
{\it line commands}.  In the case of line commands, whole lines will
be affected by the command.

The point commands are as follows:

\hskip 5ex
\kbd{h l 0 ^ \$ w W b B e E ( ) / ?\ ` f F t T \% ; ,}

The line commands are as follows:

\hskip 5ex
\kbd{j k + - H M L \{ \} G '}

These region specifiers will be referred to as {\it m} below.

\subsection{Delete/Yank/Change Commands}

\paralign to \hsize{#\tabskip=10pt plus 1 fil&#\tabskip=0pt&#\tabskip=0pt&#\cr
\fourcol{}{{\bf delete}}{{\bf yank}}{{\bf change}}
\fourcol{region determined by {\it m}}{d {\it m}}{y {\it m}}{c {\it m}}
\fourcol{... into register {\it x}}{" {\it x\/} d {\it m}}{" {\it x\/} y {\it m}}{" {\it x\/} c {\it m}}
\fourcol{a line}{d d}{Y {\rm or} y y}{c c}
\fourcol{current {\bf region}}{d r}{y r}{c r}
\fourcol{expanded {\bf region}}{d R}{y R}{c R}
\fourcol{to end of line}{D}{y \$}{c \$}
\fourcol{a character after point}{x}{y l}{c l}
\fourcol{a character before point}{DEL}{y h}{c h}
}

\vskip 2ex
\key{Overwrite {\it n} lines}{{\it n} R}

\subsection{Put Back Commands}

Deleted/yanked/changed text can be put back by the following commands.

\key{{\bf Put} back at point/above line}{P}
\key{... from register {\it x}}{" {\it x\/} P}
\key{{\bf put} back after point/below line}{p}
\key{... from register {\it x}}{" {\it x\/} p}

\subsection{Repeating and Undoing Modifications}

\key{{\bf undo} last change}{u {\rm or} :und}
\key{repeat last change}{.\ {\rm (dot)}}

Undo is undoable by \kbd{u} and repeatable by \kbd{.}.
For example, \kbd{u...} will undo 4 previous changes.
A \kbd{.} after \kbd{5dd} is equivalent to \kbd{5dd},
while \kbd{3.} after \kbd{5dd} is equivalent to \kbd{3dd}.

\section{Customization}

By default, search is case sensitive.
You can change this by including the following line in your \kbd{\~{}/.vip} file.

\hskip 5ex
\kbd{(setq viper-case-fold-search t)}

The following is a subset of the variety of
options available for customizing Viper.
See the Viper manual for details on these and other options.

\beginindentedkeys

\paralign to \hsize{#\tabskip=10pt plus 1 fil&#\tabskip=0pt&#\cr
\twocol{{\bf variable}}{{\bf default value}}
\twocol{viper-search-wrap-around}{t}
\twocol{viper-case-fold-search}{nil}
\twocol{viper-re-search}{t}
\twocol{viper-re-replace}{t}
\twocol{viper-re-query-replace}{t}
\twocol{viper-auto-indent}{nil}
\twocol{viper-shift-width}{8}
\twocol{viper-tags-file-name}{"TAGS"}
\twocol{viper-no-multiple-ESC}{t}
\twocol{viper-ex-style-motion}{t}
\twocol{viper-always}{t}
\twocol{viper-custom-file-name}{"\~{}/.vip"}
\twocol{ex-find-file-shell}{"csh"}
\twocol{ex-cycle-other-window}{t}
\twocol{ex-cycle-through-non-buffers}{t}
\twocol{blink-matching-paren}{t}
\twocol{buffer-read-only}{{\it buffer dependent}}
}

To bind keys in Vi command state, put lines like these in your
\kbd{\~{}/.vip} file:

\beginexample
(define-key viper-vi-global-user-map "\\C-v" 'scroll-down)
(define-key viper-vi-global-user-map "\\C-cm" 'smail)
\endexample


\newcolumn

\title{Ex Commands in Viper}

In vi state, an Ex command is entered by typing:

\hskip 5ex
\kbd{:\ {\sl ex-command} RET}

\section{Ex Addresses}

\paralign to \hsize{#\tabskip=5pt plus 1 fil&#\tabskip=2pt&#\tabskip=5pt plus 1 fil&#\cr
\twocolkey{current line}{.}{next line with {\sl pat}}{/ {\sl pat} /}
\twocolkey{line {\it n}}{{\it n}}{previous line with {\sl pat}}{?\ {\sl pat} ?}
\twocolkey{last line}{\$}{{\it n\/} line before {\it a}}{{\it a} - {\it n}}
\twocolkey{next line}{+}{{\it a\/} through {\it b}}{{\it a\/} , {\it b}}
\twocolkey{previous line}{-}{line marked with {\it x}}{' {\it x}}
\twocolkey{entire buffer}{\%}{previous context}{' '}
}

Addresses can be specified in front of a command.
For example,

\hskip 5ex
\kbd{:.,.+10m\$}

moves 11 lines below current line to the end of buffer.

\section{Ex Commands}

Avoid Ex text manipulation commands except substitute.
There are better VI equivalents
for all of them. Also note that all Ex commands expand \% to
current file name. To include a \% in the command, escape it with a $\backslash$.
Similarly, \# is replaced by previous file. For Viper, this is the
first  file in the {\sl :args} listing for that buffer. This defaults
to the previous file in the VI sense if you have one window.
Ex commands can be made to have history. See the manual for details.
