<para>This document is written in

<ulink url="http://docbook.org/">Docbook XML</ulink>. The source files

for this document are located in the subdirectory

<filename>doc/cookbook</filename> inside the Clutter source directory.</para>
|
|
|
|
<para>To maintain some degree of consistency, try to stick to the
|
|
following broad guidelines about how to write Docbook for this
|
|
cookbook:</para>
|
|
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para>If adding a new recipe, use the
|
|
<filename>recipe-template.xml</filename> XML file as a basis.
|
|
You can find it in the <filename><clutter source>/doc/cookbook/</filename>
|
|
directory.</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Try to indent your XML sensibly using 2 spaces per level
|
|
(we're not too strict, but some indentation helps reading
|
|
the source).</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Stick to a column width of around 80 characters.</para>
|
|
</listitem>
|

|
<para>Use the <filename> element for file
|
|
and directory names.</para>
|

</listitem>
|

<listitem>
|

<para>Use the <property> element for property names
|
|
(e.g. GObject properties).</para>

<listitem>

<para>Use the <type> element for GObject class

names.</para>

<listitem>

<para>Use the <constant> element for C defines.</para>

<listitem>
|

<para>Use the <keycap> element for keys, where
|
|
you are referring to what's actually printed on the key, e.g.
|
|
<keycap>Shift</keycap>. If you're referring to the key some
|
|
other way (e.g. "the Control key"), don't use
|
|
<keycap>.</para>
|
|
</listitem>
|
|
<listitem>
|
|
<para>Use the <function> element for functions;
|
|
the style adopted is to give the function name followed by
|
|
empty brackets, e.g. <function>clutter_actor_set_size()</function>.

</para>

</listitem>

otherwise interrupt the flow of the recipe.</para>

<para>To include a video in a recipe, do the following:</para>
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para>Make the video as short as is practical, and only include
|
|
the relevant Clutter window(s).</para>

<para>Use Ogg Theora for the encoding.</para>

<listitem>
|
|
<para>Put the file into the

<filename><clutter source>/doc/cookbook/videos</filename>

For example: <filename>animations-fading-fade-out.ogv</filename>.</para>
|

</listitem>
|

<listitem>
|
|
<para>Add the name of the file to the <varname></varname>

<para>Use an <inlinemediaobject> to include it in the

<para>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.</para>

</listitem>

</itemizedlist>
|

</listitem>
|

<listitem>
|
|
<para>To include a full code sample in a recipe (which can
|
|
be compiled into a runnable binary), do the following:</para>
|
|
|
|
<itemizedlist>
|
|
<listitem>
|
|
<para>Create a C code file in the
|
|
<filename><clutter source>/doc/cookbook/examples</filename>
|
|
directory. It should be a standalone C application (with
|
|
a <function>main()</function> etc.). The filename should be
|
|
in the format
|
|
<filename><section>-<recipe>.c</filename>; you
|
|
can add an optional identifier to the end if you have more
|
|
than one example for a recipe.</para>
|
|
|
|
<para>If you want to load image files into the application
|
|
(e.g. to demonstrate something with a texture), you can use
|
|
the <constant>TESTS_DATA_DIR</constant> variable in your C
|
|
code to reuse images in the Clutter <filename>tests</filename>
|
|
directory; this will be replaced with
|
|
<filename><clutter source>/tests/data</filename>
|
|
during the build. For example:</para>
|
|
|
|
<informalexample>
|
|
<programlisting>
|
|
<![CDATA[
|
|
clutter_texture_set_from_file (CLUTTER_TEXTURE (texture),
|
|
TESTS_DATA_DIR "/redhand.png",

&error);

|
</programlisting>
|
|
</informalexample>
|
|
</listitem>
|
|
|
|
<listitem>
|
|
<para>Edit <filename>Makefile.am</filename>
|
|
in the <filename>cookbook/examples</filename> directory
|
|
so that the build recognises the new code; e.g. if
|
|
your C source file were called
|
|
<filename>fooing-barring.c</filename> you would do:</para>
|
|
|
|
<informalexample>
|
