Contributing to this document</h1></div></div></div><p>This document is written in
<a class="ulink" href="http://docbook.org/" target="_top">Docbook XML</a>. The source files
for this document are located in the subdirectory
<code class="filename">doc/cookbook</code> inside the Clutter source directory.</p><p>To maintain some degree of consistency, try to stick to the
following broad guidelines about how to write Docbook for this
cookbook:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>If adding a new recipe, use the
<code class="filename">recipe-template.xml</code> XML file as a basis.
You can find it in the <code class="filename"><clutter source>/doc/cookbook/</code>
directory.</p></li><li class="listitem"><p>Try to indent your XML sensibly using 2 spaces per level
(we're not too strict, but some indentation helps reading
the source).</p></li><li class="listitem"><p>Stick to a column width of around 80 characters.</p></li><li class="listitem"><p>Use the <filename> element for file
and directory names.</p></li><li class="listitem"><p>Use the <property> element for property names
(e.g. GObject properties).</p></li><li class="listitem"><p>Use the <type> element for GObject class
names.</p></li><li class="listitem"><p>Use the <constant> element for C defines.</p></li><li class="listitem"><p>Use the <keycap> element for keys, where
you are referring to what's actually printed on the key, e.g.
<span class="keycap"><strong>Shift</strong></span>. If you're referring to the key some
other way (e.g. "the Control key"), don't use
<keycap>.</p></li><li class="listitem"><p>Use the <function> element for functions;
the style adopted is to give the function name followed by
empty brackets, e.g. <code class="function">clutter_actor_set_size()</code>.
</p></li><li class="listitem"><p>Use the <note> element for asides which might
otherwise interrupt the flow of the recipe.</p></li><li class="listitem"><p>To include a video in a recipe, do the following:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: circle; "><li class="listitem"><p>Make the video as short as is practical, and only include
the relevant Clutter window(s).</p></li><li class="listitem"><p>Use Ogg Theora for the encoding.</p></li><li class="listitem"><p>Put the file into the
<code class="filename"><clutter source>/doc/cookbook/videos</code>
directory. The name should be in the format
<code class="filename"><section>-<recipe>-<identifier>.ogv</code>.
For example: <code class="filename">animations-fading-fade-out.ogv</code>.</p></li><li class="listitem"><p>Add the name of the file to the <code class="varname"></code>
in the cookbook's <code class="filename">Makefile.am</code>, e.g.</p><div class="informalexample"><pre class="programlisting">VIDEO_FILES = \
videos/animations-fading-fade-out.ogv \
$(NULL)</pre></div><p>This ensures it gets included in the distribution and
installation.</p></li><li class="listitem"><p>Use an <inlinemediaobject> to include it in the
Docbook recipe file. It should look something like this:</p><div class="informalexample"><pre class="programlisting"><inlinemediaobject>
<videoobject>
<videodata fileref="videos/animations-fading-in-then-out.ogv"/>
</videoobject>
<alt>
<para>Video showing an actor fading in then out using
<type>ClutterState</type></para>
</alt>
</inlinemediaobject></pre></div><p>The <alt> tag provides the text which
is presented as a link to the file for users whose browser
doesn't support HTML 5 embedded video.</p></li></ul></div></li><li class="listitem"><p>To include a full code sample in a recipe (which can
be compiled into a runnable binary), do the following:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: circle; "><li class="listitem"><p>Create a C code file in the
<code class="filename"><clutter source>/doc/cookbook/examples</code>
directory. It should be a standalone C application (with
a <code class="function">main()</code> etc.). The filename should be
in the format
<code class="filename"><section>-<recipe>.c</code>; you
can add an optional identifier to the end if you have more
than one example for a recipe.</p><p>If you want to load image files into the application
(e.g. to demonstrate something with a texture), you can use
the <code class="constant">TESTS_DATA_DIR</code> variable in your C
code to reuse images in the Clutter <code class="filename">tests</code>
directory; this will be replaced with
<code class="filename"><clutter source>/tests/data</code>
during the build. For example:</p><div class="informalexample"><pre class="programlisting">clutter_texture_set_from_file (CLUTTER_TEXTURE (texture),
TESTS_DATA_DIR "/redhand.png",
&error);</pre></div></li><li class="listitem"><p>Edit <code class="filename">Makefile.am</code>
in the <code class="filename">cookbook/examples</code> directory
so that the build recognises the new code; e.g. if
your C source file were called
<code class="filename">fooing-barring.c</code> you would do:</p><div class="informalexample"><pre class="programlisting">noinst_PROGRAMS = \
textures-reflection \
text-shadow \
animations-rotating \
fooing-barring \
$(NULL)
fooing_barring_SOURCE = fooing-barring.c</pre></div><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>Note the second line is a new one to tell the
build where the source file is for your example.</p></div></li><li class="listitem"><p>Add a section at the end of your recipe which
XIncludes the sample code, e.g.:</p><div class="informalexample"><pre class="programlisting"><section>
<title>Full example</title>
<example id="fooing-barring-example">
<title>Fooing with a bar</title>
<programlisting>
<xi:include href="examples/fooing-barring.c" parse="text">
<xi:fallback>a code sample should be here... but isn't</xi:fallback>
</xi:include>
</programlisting>
</example>
</section></pre></div></li></ul></div></li></ul></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="effects-custom-deform.html">Prev</a> </td><td width="20%" align="center"> </td><td width="40%" align="right"> </td></tr><tr><td width="40%" align="left" valign="top">3.
