12<para>The <acronym>LFS</acronym> book installs <application>vim</application>
13as its text editor. At this point we should state that there are a
14<emphasis>lot</emphasis> of different editing applications out there including
15<application>emacs</application>, <application>nano</application>,
16<application>joe</application> and many more. Anyone who has been around the
17Internet (especially usenet) for a short time will certainly have observed at
18least one flame war, usually involving <application>vim</application> and
19<application>emacs</application> users!</para>
20
21<para>The <acronym>LFS</acronym> book gives a basic <filename>vimrc
22</filename> file. Here, we attempt to enhance this file. At startup,
23<command>vim</command> reads <filename>/etc/vimrc</filename> and
24<filename>~/.vimrc</filename> (i.e., the global
25<filename>vimrc</filename> and the user-specific one.). Note that this is
26only true if you compiled <application>vim</application> using
27<acronym>LFS</acronym>-3.1 onwards. Prior to this,
28the global <filename>vimrc</filename> was <filename>/usr/share/vim/vimrc
29</filename>.</para>
30
31<para>Here is a slightly expanded <filename>vimrc</filename> that you can
32put in <filename>/etc/vimrc</filename> to provide global effect. Of course, if
33you put it into <filename>/etc/skel/.vimrc</filename> instead, it will
34be made available to users you add to the system later. You can also copy
35the file from <filename>/etc/skel/.vimrc</filename> to
36<filename>/etc/vimrc</filename> and the home directory of users already
37on the system, like root. Be sure to set permissions, owner, and group if
38you do copy anything directly from <filename>/etc/skel</filename>.</para>

52<para>A <acronym>FAQ</acronym> on the lfs mailing lists regards the
53comment tags in <filename>vimrc</filename>. Note that they are " instead
54of the more usual # or //. This is correct, the syntax for <filename>vimrc
55</filename> is slightly unusual.</para>

57<para>We'll run through a quick explanation of what each of the
58options in this example file means here:</para>
59<itemizedlist>
60
61<listitem><para><option>set nocompatible</option> : This option
62stops <command>vim</command> from behaving in a strongly <command>vi
63</command>-compatible way. It should be at the start of any <filename>vimrc
64</filename> file as it can affect lots of other options which you may want to
65override.</para></listitem>
66
67<listitem><para><option>set bs=2</option>: This influences the behavior
68of the backspace option. It is fairly complex so see <command>:help 'bs'
69</command> for more details.</para></listitem>
70
71<listitem><para><option>set columns=80</option>: This simply sets the
72number of columns used on the screen.</para></listitem>
73
74<listitem><para><option>set background=dark</option>: This tells
75<command>vim</command> to use colors which look good on a dark
76background.</para></listitem>
77
78<listitem><para><option>set wrapmargin=8</option>: This is the number of
79characters from the right window border where wrapping starts.</para>
80</listitem>
81
82<listitem><para><option>syntax on</option>: Enables
83<command>vim</command>'s syntax highlighting.</para></listitem>
84
85<listitem><para><option>set ruler</option>: This makes <command>vim
86</command> show the current row and column at the bottom right of
87the screen.</para></listitem>
88
89
90</itemizedlist>
91
92<para>More information on the <emphasis>many</emphasis> <command>vim</command>
93options can be found by reading the help inside <command>vim</command> itself.
94Do this by typing <command>:</command><option>help</option> in
95<command>vim</command> to get the general help, or by typing <command>:
96</command><option>help usr_toc.txt</option> to view
97the User Manual Table of Contents.</para>
