<sect2 role="installation">
<title>Installation of Vim</title>

<para>First change the default locations of the <filename>vimrc</filename> and
<filename>gvimrc</filename> configuration files to <filename class="directory">/etc</filename>.</para>

<screen><userinput>echo '#define SYS_VIMRC_FILE "/etc/vimrc"' &gt;&gt; src/feature.h
echo '#define SYS_GVIMRC_FILE "/etc/gvimrc"' &gt;&gt; src/feature.h</userinput></screen>

<para>Now prepare Vim for compilation:</para>

<screen><userinput>./configure --prefix=/usr --enable-multibyte</userinput></screen>

<para>The optional <userinput>--enable-multibyte</userinput> switch
includes multibyte editing support into
vim. It is only needed for those people who ignore our recommendation not to
use LFS in locales with multibyte character sets, but it does not hurt
others.</para>

<para>Compile the package:</para>

<screen><userinput>make</userinput></screen>

<para>To test the results, you can issue:
<userinput>make test</userinput>. However, this test suite outputs a lot of
seemingly garbage characters to the screen, and this can wreak havoc with the
settings of the current terminal. Therefore the running of the test suite here
is strictly optional.</para>

<para>Now install the package:</para>

<screen><userinput>make install</userinput></screen>

<para>Many users are used to using <command>vi</command>, instead of
<command>vim</command>. To let them execute <command>vim</command> when
they habitually enter <command>vi</command>, create a symlink:</para>

<screen><userinput>ln -s vim /usr/bin/vi</userinput></screen>

<para>If you are going to install the X Window system on your LFS system, you
may want to re-compile Vim after having installed X. Vim comes with a nice GUI
version of the editor that requires X and a few other libraries to be
installed. For more information read the Vim documentation.</para>

<sect2 id="conf-vim" role="configuration"><title>Configuring Vim</title>
<indexterm zone="conf-vim"><primary sortas="e-/etc/vim">/etc/vim</primary></indexterm>

<para>By default, <command>vim</command> runs in vi-incompatible mode. Some
people might not like this, but we prefer to run <command>vim</command> in its
own mode (else we wouldn't have included it in this book, but the original
<command>vi</command>). We've included the setting of "nocompatible"
below to high-light the fact that the new behavior is being used. It
also reminds those who would change to "compatible" mode that it should
appear first because it changes other settings and overrides must come
after this setting. Create a default vim configuration file by running
the following:</para>

<screen><userinput>cat &gt; /etc/vimrc &lt;&lt; "EOF"</userinput>
" Begin /etc/vimrc

set nocompatible
set backspace=2
syntax on
set background=dark

" End /etc/vimrc
<userinput>EOF</userinput></screen>

<para>The <emphasis>set nocompatible</emphasis> makes
<command>vim</command> behave in a more useful way (the default) than the
vi-compatible manner. Remove the "no" if you want the old <command>vi</command>
behavior. The <emphasis>set backspace=2</emphasis> allows
backspacing over line breaks, autoindents and the start of insert. The
<emphasis>syntax on</emphasis> enables <command>vim</command>'s
syntax highliting, while <emphasis>set background=dark</emphasis> gives the
highliting a better color scheme for use on the black background of a linux
console.  If you later use X and terminals with a light background, changing
this will be useful.</para>

<para>Documentation for other available options can be obtained by running
the following command:</para>

<screen><userinput>vim -c ':options'</userinput></screen>
