@section Basic Concepts
|
|
|
|
We begin by explaining some basic concepts of Emacs. These concepts are
|
|
explained in more detail in the GNU Emacs Manual.
|
|
|
|
@cindex buffer
|
|
@cindex point
|
|
@cindex mark
|
|
@cindex text
|
|
@cindex looking at
|
|
@cindex end (of buffer)
|
|
@cindex region
|
|
|
|
Conceptually, a @dfn{buffer} is just a string of @acronym{ASCII} characters and two
|
|
special characters @key{PNT} (@dfn{point}) and @key{MRK} (@dfn{mark}) such
|
|
that the character @key{PNT} occurs exactly once and @key{MRK} occurs at
|
|
most once. The @dfn{text} of a buffer is obtained by deleting the
|
|
occurrences of @key{PNT} and @key{MRK}. If, in a buffer, there is a
|
|
character following @key{PNT} then we say that point is @dfn{looking at}
|
|
the character; otherwise we say that point is @dfn{at the end of buffer}.
|
|
@key{PNT} and @key{MRK} are used
|
|
to indicate positions in a buffer and they are not part of the text of the
|
|
buffer. If a buffer contains a @key{MRK} then the text between @key{MRK}
|
|
and @key{PNT} is called the @dfn{region} of the buffer.@refill
|
|
|
|
@cindex window
|
|
|
|
Emacs provides (multiple) @dfn{windows} on the screen, and you can see the
|
|
content of a buffer through the window associated with the buffer. The
|
|
cursor of the screen is always positioned on the character after @key{PNT}.
|
|
@refill
|
|
|
|
@cindex mode
|
|
@cindex keymap
|
|
@cindex local keymap
|
|
@cindex global keymap
|
|
|
|
A @dfn{keymap} is a table that records the bindings between characters and
|
|
command functions. There is the @dfn{global keymap} common to all the
|
|
buffers. Each buffer has its @dfn{local keymap} that determines the
|
|
@dfn{mode} of the buffer. Local keymap overrides global keymap, so that if
|
|
a function is bound to some key in the local keymap then that function will
|
|
be executed when you type the key. If no function is bound to a key in the
|
|
local map, however, the function bound to the key in the global map becomes
|
|
in effect.@refill

|
@node Loading VIP, Modes in VIP, Basic Concepts, Survey
|
|
@section Loading VIP
|
|
|
|
The recommended way to load VIP automatically is to include the line:
|
|
@example
|
|
(load "vip")
|
|
@end example
|
|
@noindent
|
|
in your @file{.emacs} file. The @file{.emacs} file is placed in your home
|
|
directory and it will be executed every time you invoke Emacs. If you wish
|
|
to be in vi mode whenever Emacs starts up, you can include the following
|
|
line in your @file{.emacs} file instead of the above line:
|
|
@example
|
|
(setq term-setup-hook 'vip-mode)
|
|
@end example
|
|
@noindent
|
|
(@xref{Vi Mode}, for the explanation of vi mode.)
|
|
|
|
Even if your @file{.emacs} file does not contain any of the above lines,
|
|
you can load VIP and enter vi mode by typing the following from within
|
|
Emacs.
|
|
@example
|
|
M-x vip-mode
|
|
@end example
|
|
@noindent
|
|
|
|
@node Modes in VIP, Emacs Mode, Loading VIP, Survey

@section Modes in VIP
|
|
|
|
@kindex 032 @kbd{C-z} (@code{vip-change-mode-to-vi})
|
|
@kindex 0301 @kbd{C-x C-z} (@code{suspend-emacs})
|
|
|
|
Loading VIP has the effect of globally binding @kbd{C-z} (@kbd{Control-z})
|
|
to the function @code{vip-change-mode-to-vi}. The default binding of @kbd{C-z}
|
|
in GNU Emacs is @code{suspend-emacs}, but, you can also call
|
|
@code{suspend-emacs} by typing @kbd{C-x C-z}. Other than this, all the
|
|
key bindings of Emacs remain the same after loading VIP.@refill
|
|
|
|
@cindex vi mode
|
|
|
|
Now, if you hit @kbd{C-z}, the function @code{vip-change-mode-to-vi} will be
|
|
called and you will be in @dfn{vi mode}. (Some major modes may locally bind
|
|
@kbd{C-z} to some special functions. In such cases, you can call
|
|
@code{vip-change-mode-to-vi} by @code{execute-extended-command} which is
|
|
invoked by @kbd{M-x}. Here @kbd{M-x} means @kbd{Meta-x}, and if your
|
|
terminal does not have a @key{META} key you can enter it by typing
|
|
@kbd{@key{ESC} x}. The same effect can also be achieve by typing
|
|
@kbd{M-x vip-mode}.)@refill
|
|
|
|
@cindex mode line
|
|
|
|
You can observe the change of mode by looking at the @dfn{mode line}. For
|
|
instance, if the mode line is:@refill
|
|
@example
|
|
-----Emacs: *scratch* (Lisp Interaction)----All------------
|
|
@end example
|
|
@noindent
|
|
then it will change to:
|
|
@example
|
|
-----Vi: *scratch* (Lisp Interaction)----All------------
|
|
@end example
|
|
@noindent
|
|
Thus the word @samp{Emacs} in the mode line will change to @samp{Vi}.
|
|
|
|
@cindex insert mode
|
|
@cindex emacs mode
|
|
|
|
You can go back to the original @dfn{emacs mode} by typing @kbd{C-z} in
|
|
vi mode. Thus @kbd{C-z} toggles between these two modes.@refill
|
|
|
|
Note that modes in VIP exist orthogonally to modes in Emacs. This means
|
|
that you can be in vi mode and at the same time, say, shell mode.
|
|
|
|
Vi mode corresponds to Vi's command mode. From vi mode you can enter
|
|
@dfn{insert mode} (which corresponds to Vi's insert mode) by usual Vi command
|
|
keys like @kbd{i}, @kbd{a}, @kbd{o} @dots{} etc.
|
|
|
|
In insert mode, the mode line will look like this:
|
|
@example
|
|
-----Insert *scratch* (Lisp Interaction)----All------------
|
|
@end example
|
|
@noindent
|
|
You can exit from insert mode by hitting @key{ESC} key as you do in Vi.
|
|
|
|
That VIP has three modes may seem very complicated, but in fact it is not
|
|
so. VIP is implemented so that you can do most editing remaining only
|
|
in the two modes for Vi (that is vi mode and insert mode).
|

|
|

@kindex 032 @kbd{C-z} (@code{vip-change-mode-to-vi})
|
|
|
|
You will be in this mode just after you loaded VIP. You can do all
|
|
normal Emacs editing in this mode. Note that the key @kbd{C-z} is globally
|
|
bound to @code{vip-change-mode-to-vi}. So, if you type @kbd{C-z} in this mode
|
|
then you will be in vi mode.@refill

@node Vi Mode, Insert Mode, Emacs Mode, Modes in VIP

@subsection Vi Mode
|
|
|
|
This mode corresponds to Vi's command mode. Most Vi commands work as they
|
|
do in Vi. You can go back to emacs mode by typing @kbd{C-z}. You can
|
|
enter insert mode, just as in Vi, by typing @kbd{i}, @kbd{a} etc.

@node Insert Mode, Differences from Vi, Vi Mode, Modes in VIP
|
|
@subsection Insert Mode
|
|
|
|
The key bindings in this mode is the same as in the emacs mode except for
|
|
the following 4 keys. So, you can move around in the buffer and change
|
|
its content while you are in insert mode.
|
|
|
|
@table @kbd
|
|
@item @key{ESC}
|
|
@kindex 033 @kbd{ESC} (@code{vip-change-mode-to-vi}) (insert mode)
|
|
This key will take you back to vi mode.
|
|
@item C-h
|
|
@kindex 010 @kbd{C-h} (@code{vip-delete-backward-char}) (insert mode)
|
|
Delete previous character.
|
|
@item C-w
|
|
@kindex 027 @kbd{C-w} (@code{vip-delete-backward-word}) (insert mode)
|
|
Delete previous word.
|
|
@item C-z
|
|
@kindex 032 @kbd{C-z} (@code{vip-ESC}) (insert mode)
|
|
Typing this key has the same effect as typing @key{ESC} in emacs mode.
|
|
Thus typing @kbd{C-z x} in insert mode will have the same effect as typing
|
|
@kbd{ESC x} in emacs mode.

|
|
@kindex 165 @kbd{u} (@code{vip-undo})
|
|
@kindex 056 @kbd{.} (@code{vip-repeat})
|
|
|
|
You can repeat undoing by the @kbd{.} key. So, @kbd{u} will undo
|
|
a single change, while @kbd{u .@: .@: .@:}, for instance, will undo 4 previous
|
|
changes. Undo is undoable as in Vi. So the content of the buffer will
|
|
be the same before and after @kbd{u u}.@refill

|
@node Changing, Searching, Undoing, Differences from Vi

@subsection Changing
|
|
|
|
Some commands which change a small number of characters are executed
|
|
slightly differently. Thus, if point is at the beginning of a word
|
|
@samp{foo} and you wished to change it to @samp{bar} by typing @w{@kbd{c w}},
|
|
then VIP will prompt you for a new word in the minibuffer by the prompt
|
|
@samp{foo => }. You can then enter @samp{bar} followed by @key{RET} or
|
|
@key{ESC} to complete the command. Before you enter @key{RET} or
|
|
@key{ESC} you can abort the command by typing @kbd{C-g}. In general,
|
|
@kindex 007 @kbd{C-g} (@code{vip-keyboard-quit})
|
|
you can abort a partially formed command by typing @kbd{C-g}.@refill

@subsection Searching
|
|

|
@kindex 057 @kbd{/} (@code{vip-search-forward})
|
|
@kindex 077 @kbd{?} (@code{vip-search-backward})
|
|
|
|
As in Vi, searching is done by @kbd{/} and @kbd{?}. The string will be
|
|
searched literally by default. To invoke a regular expression search,
|
|
first execute the search command @kbd{/} (or @kbd{?}) with empty search
|
|
string. (I.e, type @kbd{/} followed by @key{RET}.)
|
|
A search for empty string will toggle the search mode between vanilla
|
|
search and regular expression search. You cannot give an offset to the
|
|
search string. (It is a limitation.) By default, search will wrap around
|
|
the buffer as in Vi. You can change this by rebinding the variable
|
|
@code{vip-search-wrap-around}. @xref{Customization}, for how to do this.@refill

|
|
@kindex 1722 @kbd{z -} (@code{vip-line-to-bottom})
|
|
|
|
For those of you who cannot remember which of @kbd{z} followed by @key{RET},
|
|
@kbd{.}@: and @kbd{-} do what. You can also use @kbd{z} followed by @kbd{H},
|
|
@kbd{M} and @kbd{L} to place the current line in the Home (Middle, and
|
|
Last) line of the window.@refill
|
|
|
|
@node Counts, Marking, z Command, Differences from Vi
|
|
@subsection Counts
|
|
|
|
Some Vi commands which do not accept a count now accept one
|
|
|
|
@table @kbd
|
|
@item p
|
|
@itemx P
|
|
@kindex 160 @kbd{p} (@code{vip-put-back})
|
|
@kindex 120 @kbd{P} (@code{vip-Put-back})
|
|
Given counts, text will be yanked (in Vi's sense) that many times. Thus
|
|
@kbd{3 p} is the same as @kbd{p p p}.
|
|
@item o
|
|
@itemx O
|
|
@kindex 157 @kbd{o} (@code{vip-open-line})
|
|
@kindex 117 @kbd{O} (@code{vip-Open-line})
|
|
Given counts, that many copies of text will be inserted. Thus
|
|
@kbd{o a b c @key{ESC}} will insert 3 lines of @samp{abc} below the current
|
|
line.
|
|
@item /
|
|
@itemx ?
|
|
@kindex 057 @kbd{/} (@code{vip-search-forward})

@cindex region
|

|
|
Vi operators like @kbd{d}, @kbd{c} etc. are usually used in combination
|
|
with motion commands. It is now possible to use current region as the
|
|
argument to these operators. (A @dfn{region} is a part of buffer
|
|
delimited by point and mark.) The key @kbd{r} is used for this purpose.
|
|
Thus @kbd{d r} will delete the current region. If @kbd{R} is used instead
|
|
of @kbd{r} the region will first be enlarged so that it will become the
|
|
smallest region containing the original region and consisting of whole
|
|
lines. Thus @kbd{m .@: d R} will have the same effect as @kbd{d d}.@refill

Insert a newline and leave point before it, and then enter insert mode.
|
|
@item C-r
|
|
@kindex 022 @kbd{C-r} (@code{isearch-backward})
|
|
Backward incremental search.
|
|
@item C-s
|
|
@kindex 023 @kbd{C-s} (@code{isearch-forward})
|
|
Forward incremental search.
|
|
@item C-c

|
These keys will exit from vi mode and return to emacs mode temporarily. If
|
|
you hit one of these keys, Emacs will be in emacs mode and will believe
|
|
that you hit that key in emacs mode. For example, if you hit @kbd{C-x}
|
|
followed by @kbd{2}, then the current window will be split into 2 and you
|
|
will be in vi mode again.
|
|
@item \
|
|
@kindex 134 @kbd{\} (@code{vip-escape-to-emacs})
|
|
Escape to emacs mode. Hitting @kbd{\} will take you to emacs mode, and you
|
|
can execute a single Emacs command. After executing the Emacs command you
|
|
will be in vi mode again. You can give a count before typing @kbd{\}.
|
|
Thus @kbd{5 \ *}, as well as @kbd{\ C-u 5 *}, will insert @samp{*****}
|
|
before point. Similarly @kbd{1 0 \ C-p} will move the point 10 lines above
|
|
the current line.@refill
|
|
@item K
|
|
@kindex 113 @kbd{K} (@code{vip-kill-buffer})
|
|
Kill current buffer if it is not modified. Useful when you selected a
|
|
buffer which you did not want.
|
|
@item Q
|
|
@itemx R
|
|
@kindex 121 @kbd{Q} (@code{vip-query-replace})
|
|
@kindex 122 @kbd{R} (@code{vip-replace-string})
|
|
@kbd{Q} is for query replace and @kbd{R} is for replace. By default,
|
|
string to be replaced are treated literally. If you wish to do a regular
|
|
expression replace, first do replace with empty string as the string to be
|
|
replaced. In this way, you can toggle between vanilla and regular
|
|
expression replacement.
|
|
@item v
|
|
@itemx V
|
|
@kindex 166 @kbd{v} (@code{vip-find-file})
|
|
@kindex 126 @kbd{V} (@code{vip-find-file-other-window})
|
|
These keys are used to Visit files. @kbd{v} will switch to a buffer
|
|
visiting file whose name can be entered in the minibuffer. @kbd{V} is
|
|
similar, but will use window different from the current window.
|
|
@item #
|
|
@kindex 0430 @kbd{#} (@code{vip-command-argument})
|
|
If followed by a certain character @var{ch}, it becomes an operator whose
|
|
argument is the region determined by the motion command that follows.
|
|
Currently, @var{ch} can be one of @kbd{c}, @kbd{C}, @kbd{g}, @kbd{q} and
|
|
@kbd{s}.@refill
|
|
@item # c
|
|
@kindex 0432 @kbd{# c} (@code{downcase-region})
|
|
Change upper-case characters in the region to lower case
|
|
(@code{downcase-region}).
|
|
@item # C
|
|
@kindex 0431 @kbd{# C} (@code{upcase-region})
|
|
Change lower-case characters in the region to upper case. For instance,
|
|
@kbd{# C 3 w} will capitalize 3 words from the current point
|
|
(@code{upcase-region}).
|
|
@item # g
|
|
@kindex 0432 @kbd{# g} (@code{vip-global-execute})

@subsection New Key Bindings
|
|
|
|
In VIP the meanings of some keys are entirely different from Vi. These key
|
|
bindings are done deliberately in the hope that editing under Emacs will
|
|
become easier. It is however possible to rebind these keys to functions
|
|
which behave similarly as in Vi. @xref{Customizing Key Bindings}, for
|
|
details.
|
|
|
|
@table @kbd
|
|
@item C-g
|
|
@itemx g
|
|
@kindex 007 @kbd{C-g} (@code{vip-keyboard-quit})
|
|
@kindex 147 @kbd{g} (@code{vip-info-on-file})
|
|
In Vi, @kbd{C-g} is used to get information about the file associated to
|
|
the current buffer. Here, @kbd{g} will do that, and @kbd{C-g} is
|
|
used to abort a command (this is for compatibility with emacs mode.)
|
|
@item SPC
|
|
@itemx @key{RET}
|
|
@kindex 040 @kbd{SPC} (@code{vip-scroll})
|
|
@kindex 015 @kbd{RET} (@code{vip-scroll-back})
|
|
Now these keys will scroll up and down the text of current window.
|
|
Convenient for viewing the text.
|
|
@item s
|
|
@itemx S
|
|
@kindex 163 @kbd{s} (@code{vip-switch-to-buffer})
|
|
@kindex 123 @kbd{S} (@code{vip-switch-to-buffer-other-window})
|
|
They are used to switch to a specified buffer. Useful for switching to
|
|
already existing buffer since buffer name completion is provided. Also
|
|
a default buffer will be given as part of the prompt, to which you can
|
|
switch by just typing @key{RET} key. @kbd{s} is used to select buffer
|
|
in the current window, while @kbd{S} selects buffer in another window.
|
|
@item C
|
|
@itemx X
|
|
@kindex 103 @kbd{C} (@code{vip-ctl-c-equivalent})
|
|
@kindex 1300 @kbd{X} (@code{vip-ctl-x-equivalent})
|
|
These keys will exit from vi mode and return to emacs mode temporarily.
|
|
If you type @kbd{C} (@kbd{X}), Emacs will be in emacs mode and will believe
|
|
that you have typed @kbd{C-c} (@kbd{C-x}, resp.) in emacs mode. Moreover,
|
|
if the following character you type is an upper-case letter, then Emacs
|
|
will believe that you have typed the corresponding control character.
|
|
You will be in vi mode again after the command is executed. For example,
|
|
typing @kbd{X S} in vi mode is the same as typing @kbd{C-x C-s} in emacs
|
|
mode. You get the same effect by typing @kbd{C-x C-s} in vi mode, but
|
|
the idea here is that you can execute useful Emacs commands without typing
|
|
control characters. For example, if you hit @kbd{X} (or @kbd{C-x}) followed
|
|
by @kbd{2}, then the current window will be split into 2 and you will be in
|
|
vi mode again.@refill
|
|
@end table
|

In addition to these, @code{ctl-x-map} is slightly modified:

@kindex 1301 @kbd{X 3} (@code{vip-buffer-in-two-windows})
|
|
|
|
@table @kbd
|
|
@item X 3
|
|
@itemx C-x 3
|
|
This is equivalent to @kbd{C-x 1 C-x 2} (1 + 2 = 3).

Most Vi commands accept a @dfn{numeric argument} which can be supplied as

a prefix to the commands. A numeric argument is also called a @dfn{count}.
|
|
In many cases, if a count is given, the command is executed that many times.
|

For instance, @kbd{5 d d} deletes 5 lines while simple @kbd{d d} deletes a

In Emacs many commands are bound to the key strokes that start with

@kbd{C-x}, @kbd{C-c} and @key{ESC}. These commands can be

accessed from vi mode as easily as from emacs mode.@refill

|
Typing one of these keys have the same effect as typing it in emacs mode.
|
|
Appropriate command will be executed according as the keys you type after
|
|
it. You will be in vi mode again after the execution of the command.
|
|
For instance, if you type @kbd{@key{ESC} <} (in vi mode) then the cursor will
|
|
move to the beginning of the buffer and you will still be in vi mode.

@item C

@kindex 103 @kbd{C} (@code{vip-ctl-c-equivalent})

Typing one of these keys have the effect of typing the corresponding
|
|
control character in emacs mode. Moreover, if you type an upper-case
|
|
character following it, that character will also be translated to the
|
|
corresponding control character. Thus typing @kbd{X W} in vi mode is the
|
|
same as typing @kbd{C-x C-w} in emacs mode. You will be in vi mode again
|
|
after the execution of a command.

@item \

and you can execute a single Emacs command. After executing the
|
|
Emacs command you will be in vi mode again. You can give a count before

In Emacs the text you edit is stored in a @dfn{buffer}.

You can see the contents of buffers through @dfn{windows} created by Emacs.
|
|
When you have multiple windows on the screen only one of them is selected.
|
|
Each buffer has a unique name, and each window has a mode line which shows
|
|
the name of the buffer associated with the window and other information
|
|
about the status of the buffer. You can change the format of the mode
|
|
line, but normally if you see @samp{**} at the beginning of a mode line it
|
|
means that the buffer is @dfn{modified}. If you write out the content of
|
|
the buffer to a file, then the buffer will become not modified. Also if
|
|
you see @samp{%%} at the beginning of the mode line, it means that the file
|
|
associated with the buffer is write protected.
|

We have the following commands related to windows and buffers.

As @dfn{buffer name completion} is provided, you have only to type in
|
|
initial substring of the buffer name which is sufficient to identify it
|
|
among names of existing buffers. After that, if you hit @key{TAB} the rest
|
|
of the buffer name will be supplied by the system, and you can confirm it
|
|
by @key{RET}. The default buffer name to switch to will also be prompted,
|
|
and you can select it by giving a simple @key{RET}. See GNU Emacs Manual

|
file in the current window, you can just type @kbd{v}. Emacs maintains the
|
|
@dfn{default directory} which is specific to each buffer. Suppose, for
|
|
instance, that the default directory of the current buffer is
|
|
@file{/usr/masahiko/lisp/}. Then you will get the following prompt in the
|
|
minibuffer.@refill
|
|
@example
|
|
visit file: /usr/masahiko/lisp/
|
|
@end example
|
|
@noindent
|
|
@cindex file name completion
|
|
If you wish to visit, say, @file{vip.el} in this directory, then you can
|
|
just type @samp{vip.el} followed by @key{RET}. If the file @file{vip.el}
|
|
already exists in the directory, Emacs will visit that file, and if not,
|
|
the file will be created. Emacs will use the file name (@file{vip.el}, in
|
|
this case) as the name of the buffer visiting the file. In order to make
|
|
the buffer name unique, Emacs may append @samp{<2>}, @samp{<3>} etc., to
|
|
the buffer name. As the @dfn{file name completion} is provided here, you
|
|
can sometime save typing. For instance, suppose there is only one file in the
|
|
default directory whose name starts with @samp{v}, that is @samp{vip.el}.
|
|
Then if you just type @kbd{v @key{TAB}} then it will be completed to
|
|
@samp{vip.el}. Thus, in this case, you just have to type @kbd{v v @key{TAB}
|
|
@key{RET}} to visit @file{/usr/masahiko/lisp/vip.el}. Continuing the
|
|
example, let us now suppose that you wished to visit the file
|
|
@file{/usr/masahiko/man/vip.texinfo}. Then to the same prompt which you get
|
|
after you typed @kbd{v}, you can enter @samp{/usr/masahiko/man/vip.texinfo} or
|
|
@samp{../man/vip.texinfo} followed by @key{RET}.
|
|
|
|
Use @kbd{V} instead of @kbd{v}, if you wish to visit a file in another
|
|
window.
|
|
|
|
You can verify which file you are editing by typing @kbd{g}. (You can also
|
|
type @kbd{X B} to get nformation on other buffers too.) If you type
|
|
@kbd{g} you will get an information like below in the echo area:@refill
|
|
@example
|
|
"/usr/masahiko/man/vip.texinfo" line 921 of 1949
|
|
@end example
|
|
|
|
After you edited the buffer (@samp{vip.texinfo}, in our example) for a while,
|
|
you may wish to save it in a file. If you wish to save it in the file
|
|
associated with the buffer (@file{/usr/masahiko/man/vip.texinfo}, in this
|
|
case), you can just say @kbd{X S}. If you wish to save it in another file,
|
|
you can type @kbd{X W}. You will then get a similar prompt as you get for
|
|
@kbd{v}, to which you can enter the file name.@refill

@section Viewing the Buffer
|
|
|
|
In this and next section we discuss commands for moving around in the
|
|
buffer. These command do not change the content of the buffer. The
|
|
following commands are useful for viewing the content of the current
|
|
buffer.
|
|
|
|
@table @kbd
|

@item @key{SPC}
|
|
@itemx C-f
|
|
@kindex 040 @kbd{SPC} (@code{vip-scroll})
|
|
@kindex 006 @kbd{C-f} (@code{vip-scroll-back})
|
|
Scroll text of current window upward almost full screen. You can go
|
|
@i{forward} in the buffer by this command (@code{vip-scroll}).
|
|
@item @key{RET}
|
|
@itemx C-b
|
|
@kindex 015 @kbd{RET} (@code{vip-scroll-back})
|
|
@kindex 002 @kbd{C-b} (@code{vip-scroll-back})
|
|
Scroll text of current window downward almost full screen. You can go
|
|
@i{backward} in the buffer by this command (@code{vip-scroll-back}).
|
|
@itemx C-d
|
|
@kindex 004 @kbd{C-d} (@code{vip-scroll-up})
|
|
Scroll text of current window upward half screen. You can go
|
|
@i{down} in the buffer by this command (@code{vip-scroll-down}).
|
|
@itemx C-u
|
|
@kindex 025 @kbd{C-u} (@code{vip-scroll-down})
|
|
Scroll text of current window downward half screen. You can go
|
|
@i{up} in the buffer by this command (@code{vip-scroll-up}).
|
|
@item C-y
|
|
@kindex 031 @kbd{C-y} (@code{vip-scroll-down-one})
|
|
Scroll text of current window upward by one line (@code{vip-scroll-down-one}).
|
|
@item C-e
|
|
@kindex 005 @kbd{C-e} (@code{vip-scroll-up-one})
|
|
Scroll text of current window downward by one line (@code{vip-scroll-up-one}).
|
|
@end table
|
|
@noindent
|
|
You can repeat these commands by giving a count. Thus, @kbd{2 @key{SPC}}
|
|
has the same effect as @kbd{@key{SPC} @key{SPC}}.
|

|
@kindex 1723 @kbd{z H} (@code{vip-line-to-top})
|
|
@kindex 1721 @kbd{z RET} (@code{vip-line-to-top})
|
|
Put point on the top (@i{home}) line in the window. So the current line
|
|
becomes the top line in the window. Given a count @var{n}, point will be
|
|
placed in the @var{n}-th line from top (@code{vip-line-to-top}).

Put point on the @i{middle} line in the window. Given a count @var{n},
|
|
point will be placed in the @var{n}-th line from the middle line

The following commands are used to mark positions in the buffer.
|
|
|
|
@table @kbd
|
|
@item m @var{ch}
|
|
@kindex 155 @kbd{m} (@code{vip-mark-point})

Store current point in the register @var{ch}. @var{ch} must be a
|
|
lower-case @acronym{ASCII} letter.
|
|
@item m <
|
|
Set mark at the beginning of current buffer.
|
|
@item m >
|
|
Set mark at the end of current buffer.
|
|
@item m .
|
|
Set mark at point.
|
|
@item m ,
|
|
Jump to mark (and pop mark off the mark ring).
|
|
@end table
|
|
|
|
@cindex mark ring
|
|
|
|
Emacs uses the @dfn{mark ring} to store marked positions. The commands
|
|
@kbd{m <}, @kbd{m >} and @kbd{m .}@: not only set mark but also add it as the
|
|
latest element of the mark ring (replacing the oldest one). By repeating
|
|
the command `@kbd{m ,}' you can visit older and older marked positions. You
|
|
will eventually be in a loop as the mark ring is a ring.

@dfn{line commands}. The point commands are as follows:
|
|
@example
|
|
@kbd{h}, @kbd{l}, @kbd{0}, @kbd{^}, @kbd{$}, @kbd{w}, @kbd{W}, @kbd{b}, @kbd{B}, @kbd{e}, @kbd{E}, @kbd{(}, @kbd{)}, @kbd{/}, @kbd{?}, @kbd{`}, @kbd{f}, @kbd{F}, @kbd{t}, @kbd{T}, @kbd{%}, @kbd{;}, @kbd{,}
|
|
@end example
|
|
@noindent
|
|
The line commands are as follows:
|
|
@example
|
|
@kbd{j}, @kbd{k}, @kbd{+}, @kbd{-}, @kbd{H}, @kbd{M}, @kbd{L}, @kbd{@{}, @kbd{@}}, @kbd{G}, @kbd{'}
|
|
@end example
|
|
@noindent
|
|
@cindex expanding (region)
|
|
If a point command is given as an argument to a modifying command, the
|
|
region determined by the point command will be affected by the modifying
|
|
command. On the other hand, if a line command is given as an argument to a
|
|
modifying command, the region determined by the line command will be
|
|
enlarged so that it will become the smallest region properly containing the
|
|
region and consisting of whole lines (we call this process @dfn{expanding
|
|
the region}), and then the enlarged region will be affected by the modifying
|
|
command.

@subsection Delete Commands
|
|
|
|
@table @kbd
|
|
@item d @var{motion-command}
|
|
@kindex 1440 @kbd{d} (@code{vip-command-argument})
|
|
Delete the region determined by the motion command @var{motion-command}.
|
|
@end table
|
|
@noindent
|
|
For example, @kbd{d $} will delete the region between point and end of
|
|
current line since @kbd{$} is a point command that moves point to end of line.
|
|
@kbd{d G} will delete the region between the beginning of current line and
|
|
end of the buffer, since @kbd{G} is a line command. A count given to the
|
|
command above will become the count for the associated motion command.
|
|
Thus, @kbd{3 d w} will delete three words.
|
|
|
|
@kindex 042 @kbd{"} (@code{vip-command-argument})
|
|
It is also possible to save the deleted text into a register you specify.
|
|
For example, you can say @kbd{" t 3 d w} to delete three words and save it
|
|
to register @kbd{t}. The name of a register is a lower-case letter between
|
|
@kbd{a} and @kbd{z}. If you give an upper-case letter as an argument to
|
|
a delete command, then the deleted text will be appended to the content of
|
|
the register having the corresponding lower-case letter as its name. So,
|
|
@kbd{" T d w} will delete a word and append it to register @kbd{t}. Other
|
|
modifying commands also accept a register name as their argument, and we
|
|
will not repeat similar explanations.
|
|
|
|
We have more delete commands as below.
|

@kindex 1441 @kbd{d R}
|
|
Expand current region and delete it.
|
|
@item D
|
|
@kindex 104 @kbd{D} (@code{vip-kill-line})
|
|
Delete to the end of a line (@code{vip-kill-line}).

(@code{vip-delete-char}).
|
|
@item @key{DEL}
|
|
@kindex 177 @kbd{DEL} (@code{vip-delete-backward-char})

@subsection Yank Commands
|

|
|
@cindex yank
|
|
|
|
Yank commands @dfn{yank} a text of buffer into a (usually anonymous) register.
|
|
Here the word `yank' is used in Vi's sense. Thus yank commands do not
|
|
alter the content of the buffer, and useful only in combination with
|
|
commands that put back the yanked text into the buffer.
|
|
|
|
@table @kbd
|
|
@item y @var{motion-command}
|
|
@kindex 1710 @kbd{y} (@code{vip-command-argument})
|
|
Yank the region determined by the motion command @var{motion-command}.
|
|
@end table
|
|
@noindent
|
|
For example, @kbd{y $} will yank the text between point and the end of line
|
|
into an anonymous register, while @kbd{"c y $} will yank the same text into
|
|
register @kbd{c}.
|
|

|
|
@item y r
|
|
@kindex 1712 @kbd{y r}
|
|
Yank current region.
|

@subsection Put Back Commands
|
|
Deleted or yanked texts can be put back into the buffer by the command
|
|
below.
|
|
|
|
@table @kbd
|
|
@item p
|
|
@kindex 160 @kbd{p} (@code{vip-put-back})
|
|
Insert, after the character point is looking at, most recently
|
|
deleted/yanked text from anonymous register. Given a register name
|
|
argument, the content of the named register will be put back. Given a
|
|
count, the command will be repeated that many times. This command also
|
|
checks if the text to put back ends with a new line character, and if so
|
|
the text will be put below the current line (@code{vip-put-back}).
|
|
@item P
|
|
@kindex 120 @kbd{P} (@code{vip-Put-back})
|
|
Insert at point most recently deleted/yanked text from anonymous register.
|
|
Given a register name argument, the content of the named register will
|
|
be put back. Given a count, the command will be repeated that many times.
|
|
This command also checks if the text to put back ends with a new line
|
|
character, and if so the text will be put above the current line rather
|
|
than at point (@code{vip-Put-back}).
|
|
@end table
|
|
@noindent
|
|
@cindex number register
|
|
Thus, @kbd{" c p} will put back the content of the register @kbd{c} into the
|
|
buffer. It is also possible to specify @dfn{number register} which is a
|
|
numeral between @kbd{1} and @kbd{9}. If the number register @var{n} is
|
|
specified, @var{n}-th previously deleted/yanked text will be put back. It
|
|
is an error to specify a number register for the delete/yank commands.

Most commonly used change command takes the following form.
|
|
|
|
@table @kbd
|
|
@item c @var{motion-command}
|
|
@kindex 1430 @kbd{c} (@code{vip-command-argument})
|
|
Replace the content of the region determined by the motion command
|
|
@var{motion-command} by the text you type. If the motion command is a
|
|
point command then you will type the text into minibuffer, and if the
|
|
motion command is a line command then the region will be deleted first and
|
|
you can insert the text in @var{insert mode}.
|
|
@end table
|
|
@noindent
|
|
For example, if point is at the beginning of a word @samp{foo} and you
|
|
wish to change it to @samp{bar}, you can type @kbd{c w}. Then, as @kbd{w}
|
|
is a point command, you will get the prompt @samp{foo =>} in the
|
|
minibuffer, for which you can type @kbd{b a r @key{RET}} to complete the change
|
|
command.@refill
|
|
|
|
@table @kbd
|

Change a line. Given a count, that many lines are changed.
|
|
@item c r
|
|
@kindex 1432 @kbd{c r}
|
|
Change current region.
|

@item u
|
|
@kindex 165 @kbd{u} (@code{vip-undo})
|

Undo the last change. You can undo more by repeating undo by the repeat
|
|
command @samp{.}. For example, you can undo 5 previous changes by typing
|
|
@samp{u....}. If you type @samp{uu}, then the second @samp{u} undoes the
|
|
first undo command (@code{vip-undo}).
|
|
@item .
|
|
@kindex 056 @kbd{.} (@code{vip-repeat})
|
|
Repeat the last modifying command. Given count @var{n} it becomes the new

You can also bind @kbd{C-h} to @code{help-command} if you like.
|
|
(@xref{Customizing Key Bindings}, for details.) Binding @kbd{C-h} to
|
|
@code{help-command} has the effect of making the meaning of @kbd{C-h}

|
uniform among emacs, vi and insert modes.
|
|
|
|
When you enter insert mode, VIP records point as the start point of
|
|
insertion, and when you leave insert mode the region between point and
|
|
start point is saved for later use by repeat command etc. Therefore, repeat

|
command will not really repeat insertion if you move point by emacs
|
|
commands while in insert mode.

In vi mode, you can execute an Ex command @var{ex-command} by typing:
|
|
@example
|
|
@kbd{:@: @var{ex-command} @key{RET}}
|
|
@end example
|
|
Every Ex command follows the following pattern:
|
|
@example
|
|
@var{address command} @kbd{!}@: @var{parameters count flags}
|
|
@end example
|

|
|
In the current version of VIP, searching by Ex commands is always
|
|
@dfn{magic}. That is, search patterns are always treated as @dfn{regular
|
|
expressions}. For example, a typical forward search would be invoked by
|
|
@kbd{:/@var{pat}/}. If you wish to include @samp{/} as part of
|
|
@var{pat} you must preceded it by @samp{\}. VIP strips off these @kbd{\}'s
|
|
before @kbd{/} and the resulting @var{pat} becomes the actual search
|
|
pattern. Emacs provides a different and richer class or regular
|
|
expressions than Vi/Ex, and VIP uses Emacs' regular expressions. See GNU
|
|
Emacs Manual for details of regular expressions.
|
|
|
|
Several Ex commands can be entered in a line by separating them by a pipe
|
|
character @samp{|}.

@section Ex Command Reference
|
|
In this section we briefly explain all the Ex commands supported by VIP.
|
|
Most Ex commands expect @var{address} as their argument, and they use
|
|
default addresses if they are not explicitly given. In the following, such
|
|
default addresses will be shown in parentheses.
|
|
|
|
Most command names can and preferably be given in abbreviated forms. In
|
|
the following, optional parts of command names will be enclosed in
|
|
brackets. For example, @samp{co[py]} will mean that copy command can be
|
|
give as @samp{co} or @samp{cop} or @samp{copy}.
|
|
|
|
If @var{command} is empty, point will move to the beginning of the line
|
|
specified by the @var{address}. If @var{address} is also empty, point will
|
|
move to the beginning of the current line.
|
|
|
|
@cindex flag
|
|
|
|
Some commands accept @dfn{flags} which are one of @kbd{p}, @kbd{l} and
|
|
@kbd{#}. If @var{flags} are given, the text affected by the commands will
|
|
be displayed on a temporary window, and you will be asked to hit return to
|
|
continue. In this way, you can see the text affected by the commands
|
|
before the commands will be executed. If you hit @kbd{C-g} instead of
|
|
@key{RET} then the commands will be aborted. Note that the meaning of
|
|
@var{flags} is different in VIP from that in Vi/Ex.
|
|
|
|
@table @kbd
|
|
@item (.,.@:) co[py] @var{addr} @var{flags}
|
|
@itemx (.,.@:) t @var{addr} @var{flags}
|
|
Place a copy of specified lines after @var{addr}. If @var{addr} is
|
|
@kbd{0}, it will be placed before the first line.
|
|
@item (.,.@:) d[elete] @var{register} @var{count} @var{flags}
|
|
Delete specified lines. Text will be saved in a named @var{register} if a
|
|
lower-case letter is given, and appended to a register if a capital letter is
|
|
given.
|
|
@item e[dit] !@: +@var{addr} @var{file}
|
|
@itemx e[x] !@: +@var{addr} @var{file}
|
|
@itemx vi[sual] !@: +@var{addr} @var{file}
|
|
Edit a new file @var{file} in the current window. The command will abort
|
|
if current buffer is modified, which you can override by giving @kbd{!}.
|
|
If @kbd{+}@var{addr} is given, @var{addr} becomes the current line.
|
|
@item file
|
|
Give information about the current file.
|
|
@item (1,$) g[lobal] !@: /@var{pat}/ @var{cmds}
|
|
@itemx (1,$) v /@var{pat}/ @var{cmds}
|
|
Among specified lines first mark each line which matches the regular
|
|
expression @var{pat}, and then execute @var{cmds} on each marked line.
|
|
If @kbd{!}@: is given, @var{cmds} will be executed on each line not matching
|
|
@var{pat}. @kbd{v} is same as @kbd{g!}.
|
|
@item (.,.+1) j[oin] !@: @var{count} @var{flags}
|
|
Join specified lines into a line. Without @kbd{!}, a space character will
|
|
be inserted at each junction.
|
|
@item (.@:) k @var{ch}
|
|
@itemx (.@:) mar[k] @var{ch}
|
|
Mark specified line by a lower-case character @var{ch}. Then the
|
|
addressing form @kbd{'}@var{ch} will refer to this line. No white space is
|
|
required between @kbd{k} and @var{ch}. A white space is necessary between
|
|
@kbd{mark} and @var{ch}, however.
|
|
@item map @var{ch} @var{rhs}
|
|
Define a macro for vi mode. After this command, the character @var{ch}
|
|
will be expanded to @var{rhs} in vi mode.
|
|
@item (.,.@:) m[ove] @var{addr}
|
|
Move specified lines after @var{addr}.
|
|
@item (.@:) pu[t] @var{register}
|
|
Put back previously deleted or yanked text. If @var{register} is given,
|
|
the text saved in the register will be put back; otherwise, last deleted or
|
|
yanked text will be put back.
|
|
@item q[uit] !
|
|
Quit from Emacs. If modified buffers with associated files exist, you will
|
|
be asked whether you wish to save each of them. At this point, you may
|
|
choose not to quit, by hitting @kbd{C-g}. If @kbd{!}@: is given, exit from
|
|
Emacs without saving modified buffers.
|
|
@item (.@:) r[ead] @var{file}
|
|
Read in the content of the file @var{file} after the specified line.
|
|
@item (.@:) r[ead] !@: @var{command}
|
|
Read in the output of the shell command @var{command} after the specified
|
|
line.
|
|
@item se[t]

|
|
you can set.
|
|
@item sh[ell]
|
|
Run a subshell in a window.
|
|
@item (.,.@:) s[ubstitute] /@var{pat}/@var{repl}/ @var{options} @var{count} @var{flags}
|
|
@itemx (.,.@:) & @var{options} @var{count} @var{flags}
|
|
On each specified line, the first occurrence of string matching regular
|
|
expression @var{pat} is replaced by replacement pattern @var{repl}. Option
|
|
characters are @kbd{g} and @kbd{c}. If global option character @kbd{g}
|
|
appears as part of @var{options}, all occurrences are substituted. If
|
|
confirm option character @kbd{c} appears, you will be asked to give
|
|
confirmation before each substitution. If @kbd{/@var{pat}/@var{repl}/} is
|
|
missing, the last substitution is repeated.
|
|
@item st[op]
|
|
Suspend Emacs.
|
|
@item ta[g] @var{tag}
|
|
@cindex tag
|
|
@cindex selected tags table
|
|
Find first definition of @var{tag}. If no @var{tag} is given, previously
|
|
given @var{tag} is used and next alternate definition is find. By default,
|
|
the file @file{TAGS} in the current directory becomes the @dfn{selected tags
|
|
table}. You can select another tags table by @kbd{set} command.
|
|
@xref{Customizing Constants}, for details.
|
|
@item und[o]

|
|
Write out specified lines into file @var{file}. If no @var{file} is given,
|
|
text will be written to the file associated to the current buffer. Unless
|
|
@kbd{!}@: is given, if @var{file} is different from the file associated to
|
|
the current buffer and if the file @var{file} exists, the command will not
|
|
be executed. Unlike Ex, @var{file} becomes the file associated to the
|
|
current buffer.
|
|
@item (1,$) w[rite]>> @var{file}
|
|
Write out specified lines at the end of file @var{file}. @var{file}
|
|
becomes the file associated to the current buffer.
|
|
@item (1,$) wq !@: @var{file}

|
Same as @kbd{write} and then @kbd{quit}. If @kbd{!}@: is given, same as
|
|
@kbd{write !}@: then @kbd{quit}.
|
|
@item (.,.) y[ank] @var{register} @var{count}
|
|

|
|
specified, text will be saved in an anonymous register.
|
|
@item @var{addr} !@: @var{command}
|
|
Execute shell command @var{command}. The output will be shown in a new
|
|
window. If @var{addr} is given, specified lines will be used as standard
|
|
input to @var{command}.
|
|
@item ($) =
|
|
Print the line number of the addressed line.
|
|
@item (.,.) > @var{count} @var{flags}
|
|
Shift specified lines to the right. The variable @code{vip-shift-width}
|
|
(default value is 8) determines the amount of shift.
|
|
@item (.,.) < @var{count} @var{flags}
|
|
Shift specified lines to the left. The variable @code{vip-shift-width}
|
|
(default value is 8) determines the amount of shift.
|
|
@item (.,.@:) ~ @var{options} @var{count} @var{flags}
|
|
Repeat the previous @kbd{substitute} command using previous search pattern
|
|
as @var{pat} for matching.

@section Customizing Constants
|
|
An easy way to customize VIP is to change the values of constants used
|
|
in VIP. Here is the list of the constants used in VIP and their default
|
|
values.
|
|
|
|
@table @code
|
|
@item vip-shift-width 8
|
|
The number of columns shifted by @kbd{>} and @kbd{<} command.
|
|
@item vip-re-replace nil
|
|
If @code{t} then do regexp replace, if @code{nil} then do string replace.
|
|
@item vip-search-wrap-around t
|
|
If @code{t}, search wraps around the buffer.
|
|
@item vip-re-search nil
|
|
If @code{t} then search is reg-exp search, if @code{nil} then vanilla
|
|
search.
|
|
@item vip-case-fold-search nil
|
|
If @code{t} search ignores cases.
|
|
@item vip-re-query-replace nil
|
|
If @code{t} then do reg-exp replace in query replace.
|
|
@item vip-open-with-indent nil
|
|
If @code{t} then indent to the previous current line when open a new line
|
|
by @kbd{o} or @kbd{O} command.
|
|
@item vip-tags-file-name "TAGS"
|
|
The name of the file used as the tags table.
|
|
@item vip-help-in-insert-mode nil
|
|
If @code{t} then @key{C-h} is bound to @code{help-command} in insert mode,
|
|
if @code{nil} then it sis bound to @code{delete-backward-char}.
|
|
@end table
|
|
@noindent
|
|
You can reset these constants in VIP by the Ex command @kbd{set}. Or you
|
|
can include a line like this in your @file{.vip} file:
|
|
@example
|
|
(setq vip-case-fold-search t)
|
|

@cindex local keymap
|
|
|
|
VIP uses @code{vip-command-mode-map} as the @dfn{local keymap} for vi mode.
|
|
For example, in vi mode, @key{SPC} is bound to the function
|
|
@code{vip-scroll}. But, if you wish to make @key{SPC} and some other keys
|
|
behave like Vi, you can include the following lines in your @file{.vip}
|
|
file.
|
|
|
|
@example
|
|
(define-key vip-command-mode-map "\C-g" 'vip-info-on-file)
|
|
(define-key vip-command-mode-map "\C-h" 'vip-backward-char)
|
|
(define-key vip-command-mode-map "\C-m" 'vip-next-line-at-bol)
|
|
(define-key vip-command-mode-map " " 'vip-forward-char)
|
|
(define-key vip-command-mode-map "g" 'vip-keyboard-quit)
|
|
(define-key vip-command-mode-map "s" 'vip-substitute)
|
|
(define-key vip-command-mode-map "C" 'vip-change-to-eol)
|
|
(define-key vip-command-mode-map "R" 'vip-change-to-eol)
|
|
(define-key vip-command-mode-map "S" 'vip-substitute-line)
|
|
(define-key vip-command-mode-map "X" 'vip-delete-backward-char)
