<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>Vim has a security vulnerability already addressed upstream.  The
following patch fixes the problem:</para>

<screen><userinput>patch -Np1 -i ../&vim-security_fix-patch;</userinput></screen>

<para>Now 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 using a locale with
a multibyte character set. 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, issue: <userinput>make test</userinput>. However,
this test suite outputs a lot of binary data to the screen, which can cause
issues with the settings of the current terminal. This can be resolved by
redirecting the output to a log file.</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 users habitually enter <command>vi</command>, create a
symlink:</para>

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

<para>If an X Window System is going to be installed on the LFS
system, it may be necessary to recompile 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 and the Vim installation page
in the BLFS book at <ulink
url="&blfs-root;view/svn/postlfs/editors.html#postlfs-editors-vim"/>.</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 be the first setting in the
configuration file. This is necessary because it changes other settings, and
overrides must come after this setting. Create a default <command>vim</command>
configuration file by running the following:</para>

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

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

" End /etc/vimrc</literal>
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> to keep 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
<emphasis>if</emphasis> 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>
