| 26 | <para>The LFS book installs <application>Vim</application>
|
---|
| 27 | as its text editor. At this point we should state that there are a
|
---|
| 28 | <emphasis>lot</emphasis> of different editing applications out there including
|
---|
| 29 | <application>Emacs</application>, <application>nano</application>,
|
---|
| 30 | <application>Joe</application> and many more. Anyone who has been around the
|
---|
| 31 | Internet (especially usenet) for a short time will certainly have observed at
|
---|
| 32 | least one flame war, usually involving <application>Vim</application> and
|
---|
| 33 | <application>Emacs</application> users!</para>

|
---|
| 35 | <para>The LFS book gives a basic <filename>vimrc</filename> file. Here, we
|
---|
| 36 | attempt to enhance this file. At startup, <command>vim</command> reads
|
---|
| 37 | <filename>/etc/vimrc</filename> and <filename>~/.vimrc</filename> (i.e., the
|
---|
| 38 | global <filename>vimrc</filename> and the user-specific one.). Note that this is
|
---|
| 39 | only true if you compiled <application>vim</application> using LFS-3.1 onwards.
|
---|
| 40 | Prior to this, the global <filename>vimrc</filename> was
|
---|
| 41 | <filename>/usr/share/vim/vimrc</filename>.</para>
|
---|
| 42 |
|
---|
| 43 | <para>Here is a slightly expanded <filename>.vimrc</filename> that you can
|
---|
| 44 | put in <filename>~/.vimrc</filename> to provide user specific effects. Of
|
---|
| 45 | course, if you put it into <filename>/etc/skel/.vimrc</filename> instead, it
|
---|
| 46 | will be made available to users you add to the system later. You can also copy
|
---|
| 47 | the file from <filename>/etc/skel/.vimrc</filename> to the home directory of
|
---|
| 48 | users already on the system, like root. Be sure to set permissions, owner, and
|
---|
| 49 | group if you do copy anything directly from
|
---|
| 50 | <filename class="directory">/etc/skel</filename>.</para>

| 60 | <para>A FAQ on the LFS mailing lists regards the comment tags in

| 73 | </command>-compatible way. It should be at the start of any <filename>vimrc
