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

<para>First, unpack both
<filename>vim-&vim-version;.tar.bz2</filename> and (optionally)
<filename>vim-&vim-version;-lang.tar.gz</filename> archives into the
same directory. Then 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>Prepare Vim for compilation:</para>

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

<para>The optional but highly recommended
<parameter>--enable-multibyte</parameter> switch includes support for
editing files in multibyte character encodings into
<command>vim</command>.  This is needed if the recommendation was not
heeded to not to use LFS in locales with multibyte character sets.
This switch is also helpful to be able to edit text files initially
created in Linux distributions like Fedora Core that use UTF-8 as a
default character set.</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 chaotic characters to the screen, which can cause issues with
the settings of the current terminal. Therefore, running the test
suite here is strictly optional.</para>

<para>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 allow execution of <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 the X Window system is going to be installed on the LFS
system, it may be necessary to re-compile Vim after installing X. Vim
comes with a GUI version of the editor that requires X and some
additional libraries to be installed. For more information on this
process, refer to the Vim documentation.</para>

</sect2>

<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.
This may be new to users who have used other editors in the past. The
<quote>nocompatible</quote> setting is included below to highlight the
fact that a new behavior is being used. It also reminds those who
would change to <quote>compatible</quote> mode that it should appear
first.  This is necessary 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"
" Begin /etc/vimrc

set nocompatible
set backspace=2
syntax on
if (&amp;term == "iterm") || (&amp;term == "putty")
  set background=dark
endif

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

<para>The <parameter>set nocompatible</parameter> makes
<command>vim</command> behave in a more useful way (the default) than
the vi-compatible manner. Remove the <quote>no</quote> if you want the
old <command>vi</command> behavior. The <parameter>set
backspace=2</parameter> allows backspacing over line breaks,
autoindents, and the start of insert. The <parameter>syntax
on</parameter> enables vim's syntax highlighting. Finally, the
<parameter>if</parameter> statement with the <parameter>set
background=dark</parameter> corrects <command>vim</command>'s guess
about the background color of some terminal emulators. This gives the
highlighting a better color scheme for use on the black background of
these programs.</para>

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

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