<title>The VI Input Mode</title>

<sect1 id="vi-mode-sect1">
<title>VI Input Mode</title>

<para>The goal of the VI mode is not to be a complete replacement
for Vim and support all Vim’s features. Its aim is to make
the <quote>Vim way</quote> of text editing - and the Vim habits learned -
available for programs using the &kappname; text editor as their internal editor.</para>

<para>The VI mode aims integrate nicely with the programs and deviate
from Vim’s behavior where it makes sense. For example,
<userinput><command>:w</command></userinput> will open a save dialog in &kappname;’s VI mode.</para>

<para>To enable the VI input mode for all new views, go to
<menuchoice><guimenu>Settings</guimenu><guimenuitem>Configure &kappname;...</guimenuitem>
<guimenu>Editing</guimenu><guimenuitem>VI Input Mode</guimenuitem></menuchoice>.
On this tab you can set options for the VI Input Mode and define and edit
the key mapping in this mode.
VI Input Mode can also be toggled with the <guimenuitem>VI Input Mode</guimenuitem>
setting in the <guimenu>Edit</guimenu> menu. (The default shortcut key is
<keycombo action="simul"><keysym>Meta</keysym>&Ctrl;<keycap>V</keycap></keycombo>
 - where <keysym>Meta</keysym> usually is the <keysym>Windows</keysym> key).</para>

<note>
<para>Many Vi Mode keyboard commands are case-sensitive, unlike most &kde;
keyboard shortcuts.  That means that <userinput>y</userinput> and
<userinput>Y</userinput> are different commands.  To enter the
<userinput>y</userinput> (yank) command, make sure <keysym>Caps Lock</keysym> is
disabled and press <keycap>Y</keycap>.  To enter the <userinput>Y</userinput>
(yank to end of line) command, 
<keycombo action="simul">&Shift;<keycap>Y</keycap></keycombo>.</para>

<para>This does not apply to commands that use the &Ctrl; key, which may be
entered regardless of <keycap>Caps Lock</keycap> mode and without pressing 
&Shift;.  However, some commands require the use of &Ctrl;-key combination
followed by another key which is case sensitive.  For instance, to input
<quote><keycombo action="simul">&Ctrl;<keycap>W</keycap></keycombo>,
<userinput>h</userinput></quote> (switch to split view right) make sure
<keycap>Caps Lock</keycap> is disabled, press
<keycombo action="simul">&Ctrl;<keycap>W</keycap></keycombo>, release, and
then press <keycap>H</keycap>.</para>
</note>

<sect2 id="vi-incompatibilities">
<title>Incompatibilities with Vim</title>

<para>There are only a few features of &kappname;’s VI mode which are incompatible
with Vim (not counting things missing). They are listed below together
with the respective reasons.</para>
<itemizedlist>
<listitem>
<para>&kappname;: <userinput>U</userinput> and
<keycombo action="simul">&Ctrl;<keycap>R</keycap></keycombo> is redo.</para>
<para>Vim: <keycombo action="simul">&Ctrl;<keycap>R</keycap></keycombo> is
normal redo, <keycap>U</keycap> is used to undo all latest changes on one line.</para>
<para>The reason for having <keycap>U</keycap> act as redo in &kappname;’s VI mode is
that the shortcut <keycombo action="simul">&Ctrl;<keycap>R</keycap></keycombo>
by default is taken by &kappname;’s replace function (search and replace). By default,
the VI mode won’t override &kappname;’s shortcuts (this can be configured in
<menuchoice><guimenu>Settings</guimenu><guimenuitem>Configure &kappname;...</guimenuitem>
<guimenu>Editing</guimenu><guimenuitem>Vi Input Mode</guimenuitem></menuchoice>),
therefore a redo-action needs to be available as a <quote>regular</quote> key press, too.
Besides, the behavior of the <userinput>U</userinput> command in Vim does not map well
to &kappname;’s internal undo system, so it would be non-trivial to support anyway.</para>
</listitem>
<listitem>
<para>&kappname;: <userinput><command>print</command></userinput> shows the <guilabel>Print</guilabel> dialog.</para>
<para>Vim: <userinput><command>print</command></userinput> prints the lines of
the given range like its grandfather ed.</para>
<para>Commands like <userinput><command>:print</command></userinput> are available
not only in the VI mode but for users using <quote>regular</quote> &kappname;, too - therefore
the <userinput><command>:print</command></userinput> command opens
the print dialog - following the principle of least surprise instead of
mimicking Vim’s behavior.</para>
</listitem>
<listitem>
<para>&kappname;: <userinput>Y</userinput> yanks to end of line.</para>
<para>Vim: <userinput>Y</userinput> yanks whole line, just like
<userinput>y</userinput><userinput>y</userinput>.</para>
<para>VI’s behavior for the <userinput>Y</userinput> command is in practice a bug.
For both change and delete commands,
<userinput>c</userinput><userinput>c</userinput>/
<userinput>d</userinput><userinput>d</userinput> will do its action on
the current line and <userinput>C</userinput>/<userinput>D</userinput> will work from the
cursor column to the end of the line. However, both
<userinput>y</userinput><userinput>y</userinput> and <userinput>Y</userinput>
yanks the current line. In &kappname;’s VI Mode <userinput>Y</userinput> will yank to the end
of the line. This is described as <quote>more logical</quote> in the Vim
<ulink url="http://vimdoc.sourceforge.net/htmldoc/change.html#Y">documentation</ulink>.
</para>
</listitem>
<listitem>
<para>&kappname;: <userinput>O</userinput> and <userinput>o</userinput> opens [<replaceable>count</replaceable>] new lines
and puts you in insert mode.</para>
<para>Vim: <userinput>O</userinput> and <userinput>o</userinput> opens a new line and inserts
text [<replaceable>count</replaceable>] times when leaving insert mode.</para>
<para>This is mostly done as a consequence of witnessing many people being
confused by this behavior on a vim irc channel (#vim on freenode).</para>

<para>Visual Mode is entered automatically when text is selected with the mouse.
It is also entered when using functions of Kate that select text, such as Select

<para>Vi marks and <link linkend="kate-part-bookmarks">Kate bookmarks</link> are

a Kate bookmark is created, a corresponding Vi mark at the 0 column is also
created.</para>

<title>The Comma Text Object</title>

<para>This object is missing in Vim. The comma text object
makes it easy to modify parameter lists in C-like languages and other comma
separated lists. It is basically the area between two commas or between a comma
and a bracket. In the line shown in the illustration to the right, the three
ranges this text object can span are highlighted in red.</para>

<caption><para>Comma text object ranges. If the cursor is over &eg;
<replaceable>arg2</replaceable>, pressing
<userinput>ci</userinput>, (<quote>change inner comma</quote>)
would delete <replaceable>double arg2</replaceable> and place the cursor between
the two commas in insert mode. A very convenient way to change a function's
parameters.</para></caption>

<title>Missing Features</title>

<para>As stated earlier, the goal of &kappname;’s VI Mode is not to support 100% of
Vim’s features, however, there are some features which are sorely missed:</para>
<itemizedlist>
<listitem>
<para>Visual block mode - especially the ability to prepend/append text to the
visual block selection.</para></listitem>
<listitem>
<para>Having ex commands available in other programs than the &kappname; application.</para></listitem>
<listitem>
<para>The search code needs improvement and the <userinput>*</userinput> and
<userinput>#</userinput>commands should just be regular searches.</para></listitem>
