  <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, patch Vim with several fixes from upstream
    developers since the initial release of Vim-&vim-version;:</para>

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

    <para>This version of Vim installs translated man pages and places
    them into directories that will not be searched by Man-DB. Patch Vim
    so that it installs its man pages into searchable directories and
    ultimately allows Man-DB to transcode the page into the desired format
    at run-time:</para>

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

    <para>Finally, change the default location of the
    <filename>vimrc</filename> configuration file to <filename
    class="directory">/etc</filename>:</para>

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

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

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

    <variablelist>
      <title>The meaning of the configure options:</title>

      <varlistentry>
        <term><parameter>--enable-multibyte</parameter></term>
        <listitem>
          <para>This switch enables support for editing files in multibyte
          character encodings.  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>
        </listitem>
      </varlistentry>

    </variablelist>

    <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>In UTF-8 locales, the <command>vimtutor</command> program tries to
    convert the tutorials from ISO-8859-1 to UTF-8. Since some tutorials are
    not in ISO-8859-1, the text in them is thus made unreadable. If you
    unpacked the <filename>vim-&vim-version;-lang.tar.gz</filename> archive
    and are going to use a UTF-8 based locale, remove non-ISO-8859-1 tutorials.
    An English tutorial will be used instead.</para>
    <!-- Removal is used instead of conversion in order for the user to be able to
    painlessly revert his UTF-8 locale choice. -->

<screen><userinput>rm -f /usr/share/vim/vim70/tutor/tutor.{gr,pl,ru,sk}
rm -f /usr/share/vim/vim70/tutor/tutor.??.*</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 for both the binary and the man-page:</para>

<screen><userinput>ln -sv vim /usr/bin/vi
ln -sv vim.1 /usr/share/man/man1/vi.1</userinput></screen>

    <para>By default, Vim's documentation is installed in <filename
    class="directory">/usr/share/vim</filename>. The following symlink
    allows the documentation to be accessed via <filename
    class="directory">/usr/share/doc/vim-&vim-version;</filename>, making
    it consistent with the location of documentation for other packages:</para>

<screen><userinput>ln -sv ../vim/vim70/doc /usr/share/doc/vim-&vim-version;</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/vimrc">/etc/vimrc</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 role="nodump"><userinput>vim -c ':options'</userinput></screen>

    <note>
      <para>By default, Vim only installs spell files for the English language.
      To install spell files for your preferred language, please read the README
      file located here: <ulink url="ftp://ftp.vim.org/pub/vim/runtime/spell/" /></para>
