<chapter id="source">
<title>PostgreSQL Source Code</title>
<sect1 id="source-format">
<title>Formatting</title>
<para>
Source code formatting uses a 4 column tab spacing, currently with
tabs preserved (i.e. tabs are not expanded to spaces).
</para>
<para>
For Emacs, add the following (or something similar)
to your <filename>~/.emacs</filename>
initialization file:
<programlisting>
;; check for files with a path containing "postgres" or "pgsql"
(setq auto-mode-alist
(cons '("\\(postgres\\|pgsql\\).*\\.[ch]\\'" . pgsql-c-mode)
auto-mode-alist))
(setq auto-mode-alist
(cons '("\\(postgres\\|pgsql\\).*\\.cc\\'" . pgsql-c-mode)
auto-mode-alist))
(defun pgsql-c-mode ()
;; sets up formatting for PostgreSQL C code
(interactive)
(c-mode)
(setq-default tab-width 4)
(c-set-style "bsd") ; set c-basic-offset to 4, plus other stuff
(c-set-offset 'case-label '+) ; tweak case indent to match PG custom
(setq indent-tabs-mode t)) ; make sure we keep tabs when indenting
</programlisting>
</para>
<para>
For <application>vi</application>, your
<filename>~/.vimrc</filename> or equivalent file should contain
the following:
<programlisting>
set tabstop=4
</programlisting>
or equivalently from within vi, try
<programlisting>
:set ts=4
</programlisting>
</para>
<para>
The text browsing tools <application>more</application> and
<application>less</application> can be invoked as
<programlisting>
more -x4
less -x4
</programlisting>
</para>
