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

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

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

    <para>Disable a test that fails:</para>

<screen><userinput remap="pre">sed -i '/call/{s/split/xsplit/;s/303/492/}' src/testdir/test_recover.vim</userinput></screen>

    <para>Prepare Vim for compilation:</para>

<screen><userinput remap="configure">./configure --prefix=/usr</userinput></screen>

    <para>Compile the package:</para>

<screen><userinput remap="make">make</userinput></screen>

    <para>To test the results, issue:</para>

<screen><userinput remap="test">make -j1 test &amp;&gt; vim-test.log</userinput></screen>

    <para>The test suite outputs a lot of binary data to the screen.  This can
    cause issues with the settings of the current terminal.  The problem can be
    avoided by redirecting the output to a log file as shown above.  A
    successful test will result in the words "ALL DONE" in the log file
    at completion.</para>

    <para>Install the package:</para>

<screen><userinput remap="install">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 for both the binary and the man page in the provided
    languages:</para>

<screen><userinput remap="install">ln -sv vim /usr/bin/vi
for L in  /usr/share/man/{,*/}man1/vim.1; do
    ln -sv vim.1 $(dirname $L)/vi.1
done</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 remap="install">ln -sv ../&vim-docdir;/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-book;postlfs/vim.html"/>.</para>

  <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

" Ensure defaults are set before customizing settings, not after
source $VIMRUNTIME/defaults.vim
let skip_defaults_vim=1 

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


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

    <para>The <parameter>set nocompatible</parameter> setting 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>
    setting allows backspacing over line breaks, autoindents, and the start of
    insert. The <parameter>syntax on</parameter> parameter enables vim's syntax
    highlighting.  The <parameter>set mouse=</parameter> setting enables
    proper pasting of text with the mouse when working in chroot or over a
    remote connection.  Finally, the <emphasis>if</emphasis> statement with the
    <parameter>set background=dark</parameter> setting 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>Creating an empty <filename>~/.vimrc</filename> prevents vim from
    overriding settings in <filename>/etc/vimrc</filename> by using
    <filename>/usr/share/vim/vim80/defaults.vim</filename>.</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, download the
      <filename>*.spl</filename> and optionally, the <filename>*.sug</filename>
      files for your language and character encoding from <ulink
      url="ftp://ftp.vim.org/pub/vim/runtime/spell/"/> and save them to
      <filename class='directory'>/usr/share/&vim-docdir;/spell/</filename>.</para>

      <para>To use these spell files, some configuration in
      <filename>/etc/vimrc</filename> is needed, e.g.:</para>

<screen><literal>set spelllang=en,ru
set spell</literal></screen>

      <para>For more information, see the appropriate README file located
      at the URL above.</para>
