16<para>The <acronym>LFS</acronym> book installs <application>vim</application>
17as its text editor. At this point we should state that there are a
18<emphasis>lot</emphasis> of different editing applications out there including
19<application>emacs</application>, <application>nano</application>,
20<application>joe</application> and many more. Anyone who has been around the
21Internet (especially usenet) for a short time will certainly have observed at
22least one flame war, usually involving <application>vim</application> and
23<application>emacs</application> users!</para>
24
25<para>The <acronym>LFS</acronym> book gives a basic <filename>vimrc
26</filename> file. Here, we attempt to enhance this file. At startup,
27<command>vim</command> reads <filename>/etc/vimrc</filename> and
28<filename>~/.vimrc</filename> (i.e., the global
29<filename>vimrc</filename> and the user-specific one.). Note that this is
30only true if you compiled <application>vim</application> using
31<acronym>LFS</acronym>-3.1 onwards. Prior to this,
32the global <filename>vimrc</filename> was <filename>/usr/share/vim/vimrc
33</filename>.</para>
34
35<para>Here is a slightly expanded <filename>vimrc</filename> that you can
36put in <filename>/etc/vimrc</filename> to provide global effect. Of course, if
37you put it into <filename>/etc/skel/.vimrc</filename> instead, it will
38be made available to users you add to the system later. You can also copy
39the file from <filename>/etc/skel/.vimrc</filename> to
40<filename>/etc/vimrc</filename> and the home directory of users already
41on the system, like root. Be sure to set permissions, owner, and group if
42you do copy anything directly from <filename>/etc/skel</filename>.</para>

56<para>A <acronym>FAQ</acronym> on the lfs mailing lists regards the
57comment tags in <filename>vimrc</filename>. Note that they are " instead
58of the more usual # or //. This is correct, the syntax for <filename>vimrc
59</filename> is slightly unusual.</para>

61<para>We'll run through a quick explanation of what each of the
62options in this example file means here:</para>
63<itemizedlist>
64
65<listitem><para><option>set nocompatible</option> : This option
66stops <command>vim</command> from behaving in a strongly <command>vi
67</command>-compatible way. It should be at the start of any <filename>vimrc
68</filename> file as it can affect lots of other options which you may want to
69override.</para></listitem>
70
71<listitem><para><option>set bs=2</option>: This influences the behavior
72of the backspace option. It is fairly complex so see <command>:help 'bs'
73</command> for more details.</para></listitem>
74
75<listitem><para><option>set columns=80</option>: This simply sets the
76number of columns used on the screen.</para></listitem>
77
78<listitem><para><option>set background=dark</option>: This tells
79<command>vim</command> to use colors which look good on a dark
80background.</para></listitem>
81
82<listitem><para><option>set wrapmargin=8</option>: This is the number of
83characters from the right window border where wrapping starts.</para>
84</listitem>
85
86<listitem><para><option>syntax on</option>: Enables
87<command>vim</command>'s syntax highlighting.</para></listitem>
88
89<listitem><para><option>set ruler</option>: This makes <command>vim
90</command> show the current row and column at the bottom right of
91the screen.</para></listitem>
92
93
94</itemizedlist>
95
96<para>More information on the <emphasis>many</emphasis> <command>vim</command>
97options can be found by reading the help inside <command>vim</command> itself.
98Do this by typing <command>:</command><option>help</option> in
99<command>vim</command> to get the general help, or by typing <command>:
100</command><option>help usr_toc.txt</option> to view
101the User Manual Table of Contents.</para>
