<para>The LFS book installs vim as its editor. At this point we should
|
|
state that there are a <emphasis>lot</emphasis> of different editors out
|
|
there including emacs, nano, joe and many more. Anyone who has been
|
|
around the Internet (especially usenet) for a short time will certainly
|
|
have observed at least one flame war, usually involving vim and emacs
|
|
users!</para>
|
|
|
|
<para>The LFS book gives a basic <filename>vimrc</filename> file. Here,
|
|
we attempt to enhance this file. At startup, vim reads
|
|
<filename>/etc/vimrc</filename> and <filename>~/.vimrc</filename>
|
|
(i.e., the global vimrc and the user-specific one.). Note that this is
|
|
only true if you compiled vim using LFS-3.1 onwards. Prior to this,
|
|
the global vimrc was <filename>/usr/share/vim/vimrc</filename>.</para>
|
|
|
|
<para>Here is an example of a slightly expanded vimrc:</para>
|
|
|
|
<para><screen>" Begin .vimrc
|
|
|
|
set nocompatible
|
|
set bs=2
|
|
set columns=80
|
|
set background=dark
|
|
set tabstop=8
|
|
set wrapmargin=8
|
|
set nobk
|
|
syntax on
|
|
set ruler
|
|
set noexpandtab
|
|
|
|
" End .vimrc</screen></para>
|
|
|
|
<para>A FAQ on the lfs lists regards the comment tags in vimrc. Note
|
|
that they are " instead of the more usual # or //. This is correct, the
|
|
syntax for vimrc is slightly unusual.</para>
|
|
|
|
<para>We'll run through a quick explanation of what each of the
|
|
options in this example file means here:</para>
|
|
<itemizedlist>
|
|
<listitem><para><userinput>set nocompatible :</userinput>
|
|
This option stops vim from behaving in a strongly vi-compatible way. It
|
|
should be at the start of any vimrc file as it can affect lots of other
|
|
options which you may want to override.</para></listitem>
|
|
|
|
<listitem><para><userinput>set bs=2 :</userinput>
|
|
This influences the behaviour of the backspace option. It is fairly
|
|
complex so see <userinput>:help 'bs'</userinput> for more
|
|
details.</para></listitem>
|
|
|
|
<listitem><para><userinput>set columns=80 :</userinput>
|
|
This simply sets the number of columns used on the
|
|
screen.</para></listitem>
|
|
|
|
<listitem><para><userinput>set background=dark :</userinput>
|
|
This tells vim to use colours which look good on a dark
|
|
background.</para></listitem>
|
|
|
|
<listitem><para><userinput>set tabstop=8 :</userinput>
|
|
The number of spaces which a tabstop takes.</para></listitem>
|
|
|
|
<listitem><para><userinput>set wrapmargin=8 :</userinput>
|
|
This is the number of characters from the right window
|
|
border where wrapping starts.</para></listitem>
|
|
|
|
<listitem><para><userinput>set nobk :</userinput>
|
|
This stops vim from creating a backup before
|
|
overwriting a file.</para></listitem>
|
|
|
|
<listitem><para><userinput>syntax on :</userinput>
|
|
Enables vim's syntax highlighting.</para></listitem>
|
|
|
|
<listitem><para><userinput>set ruler :</userinput>
|
|
This makes vim show the current row and column at the bottom right of
|
|
the screen.</para></listitem>
|
|
|
|
<listitem><para><userinput>set noexpandtab :</userinput>
|
|
This makes vim insert tabs as tab characters instead of as a set of
|
|
spaces.</para></listitem>
|
|
|
|
</itemizedlist>

|
|
|
<para>More information on the <emphasis>many</emphasis> vim options
|
|
can be found by reading the help inside vim itself. Do this by typing
|
|
<userinput>:help</userinput> in vim to get the general help, or by
|
|
typing <userinput>:help usr_toc.txt</userinput> to view the User Manual
|
|
Table of Contents.</para>
