This is a guide for those who wish to hack on the MPD source
|
|
code. MPD is an open project, and we are always happy about
|
|
contributions. So far, more than 50 people have contributed
|
|
patches.

Always write your code against the latest git:
|
|
</para>
|
|
|
|
<programlisting>git clone git://git.musicpd.org/master/mpd.git</programlisting>
|
|
|
|
<para>
|
|
Configure with the options <option>--enable-debug
|
|
--enable-werror</option>. Enable as many plugins as possible,
|
|
to be sure that you don't break any disabled code.

Don't mix several changes in one single patch. Create a
|
|
separate patch for every change. Tools like
|
|
<application>stgit</application> help you with that.
