<para>

<varname>{cycle}</varname> is used to alternate a set of values.
|
|
This makes it easy to for example, alternate between two or more colors
|
|
in a table, or cycle through an array of values.

You can <varname>{cycle}</varname> through more than one set of values in
|
|
a template by supplying a <parameter>name</parameter> attribute.
|
|
Give each <varname>{cycle}</varname> an unique <parameter>name</parameter>.
|
|
</para></listitem>
|
|
<listitem><para>
|
|
You can force the current value not to print with the
|
|
<parameter>print</parameter> attribute set to &false;. This would be useful
|
|
for silently skipping a value.
|
|
</para></listitem>
|
|
<listitem><para>
|
|
The <parameter>advance</parameter> attribute is used to repeat a value.
|
|
When set to &false;, the next call to <varname>{cycle}</varname> will print
|
|
the same value.
|
|
</para></listitem>
|
|
<listitem><para>
|
|
If you supply the <parameter>assign</parameter> attribute, the output of the
|
|
<varname>{cycle}</varname> function will be assigned to a template variable
|
|
instead of being output to the template.
