<p>Variables are either simple string, tables, conditionals or callbacks.</p>
<p>A simple string is set with <code class="code">template#set "name" s</code> where <code class="code">s</code>
will be automatically escaped depending on the declaration in
the template:</p>
<ul>
<li><code class="code">::name::</code> does no escaping;</li>
<li><code class="code">::name_url::</code> escapes for URL encoding, make it suitable in a
link <code class="code"><a href="::name_url::"></code>;</li>
<li><code class="code">::name_html::</code> escapes for HTML display of the string;</li>
<li><code class="code">::name_html_tag::</code> escapes the string to make it suitable to be
placed between quotes in an HTML tag, e.g.
<code class="code"><input value="::name_html_tag::"></code>;</li>
<li><code class="code">::name_html_textarea::</code> escapes the string to make it suitable
to be placed between <code class="code"><textarea>...</textarea></code>.</li>
</ul>
<p>Tables are declared in the template by <code class="code">::table(name)::</code> <i>row
template</i> <code class="code">::end::</code>. The <i>row template</i> can contain other
variables. Calling <code class="code">template#table "name" rows</code>, where <code class="code">rows</code> is
a list <code class="code">[row1, row2,...,rowN]</code>, will insert <code class="code">N</code> <i>row templates</i>
with each template having its variables set thanks to <code class="code">row1</code>,...
each of which is an associative list name -> value (of type
<code class="code">Template.table_row</code>).</p>
<p>Conditionals are declared in the template by <code class="code">::if(name)
.. ::else:: .. ::end::</code> with the "else" clause being optional.
Calling <code class="code">template#conditional</code> sets up a conditional value.</p>
<p>Calling <code class="code">template#callback "fname" f</code> sets up the callback
function declared by <code class="code">::call(fname,arg1,...,argN)::</code> replacing the
call by the value of <code class="code">f</code> applied to the list <code class="code">[arg1,...,argN]</code>.
The string returned by <code class="code">f</code> can be escaped by using suffices in the
template as for simple tags: <code class="code">::call(fname,arg1,...,argN)_html::</code>,...</p>
<p>A template may also include other templates with <code class="code">::include(filename)::</code>.</p>
