<div id="content"><div id="content-area"><div id="article-title">YHTML-TEMPLATE</div><div id="article">YHTML-Template is an <a href="HTML template.html" class="category">HTML template</a> library based on Edi Weitz's <a href="HTML-TEMPLATE.html" class="internal">HTML-TEMPLATE</a>. It was written by <a href="Dmitri Ivanov.html" class="internal">Dmitri Ivanov</a>.<p>License: <a href="LLGPL.html" class="internal">LLGPL</a><p>Homepage: <a href="http://lisp.ystok.ru/yhtml/html-template.html">http://lisp.ystok.ru/yhtml/html-template.html</a>.<p> YHTML-Template is a part of <a href="YstokHTML.html" class="internal">YstokHTML</a> collection. It accepts more "Lispy" expressions and provides the following extensions to the original <a href="HTML-TEMPLATE.html" class="internal">HTML-TEMPLATE</a> code. <p><ol>
|
|
<li>A Lisp form in place of "plane attribute" is allowed.
|
|
Forms are read by the standard read function.
|
|
All starting tags (except </li>
|
|
</ol><code>TMPL_INCLUDE</code>) accept forms
|
|
instead of "old style" attributes.<br><p> The <code>*attributes-are-lisp-forms*</code> special variable was introduced.
|
|
Bind or set it to NIL to treating those tags in the compatibility mode.<p><li>Symbols follow standard Lisp syntax: a package specifier is allowed
|
|
in front of the name. By default, symbols are interned into the
|
|
package stored in *template-package*, a new special variable.
|
|
</li>
|
|
<li>To interpret the forms in run-time, the </li><code>template-eval</code> was introduced.
|
|
It is a simple evaluator akin to the standard <code>eval</code> function except for:
|
|
<ul>
|
|
<li>A limited number of special-forms is supported, namely:
|
|
</li>
|
|
</ul><code>IF WHEN UNLESS AND OR NOT QUOTE</code>.
|
|
<li>The symbol with a name like *var* is treated as a dynamic variable
|
|
and is retrieved via </li><code>symbol-value</code>.
|
|
<li>The values of other symbols are looked up via *value-access-function*.
|
|
|
|
</li><li>The </li><code>TMPL_EVAL</code> tag and create-eval-printer were introduced;
|
|
the former should be used instead of the <code>TMPL_VAR</code> tag.<p><li>The value of </li><code>*format-non-strings*</code> has got an additional meaning.
|
|
If it equals to <code>T</code>, the result is produced by means of
|
|
<code>princ-to-string</code>, i.e. <code>(format nil "~A" ...)</code>.<br>
|
|
If it is true but not equals to T, the value must be a single-parameter
|
|
function, which returns two values:<br>
|
|
(1) a string resulted from its argument, and optionally<br>
|
|
(2) <var>do-not-modify</var> flag controlling whether <code>*string-modifier*</code>
|
|
is applied afterwards.<br>
|
|
The truth as second value can prevent the result of converting
|
|
from predefined format, e.g. LHTML, from further escaping.<p><li>Tag </li><code>TMPL_ELSE</code> and all ending tags <code>/TMPL_...</code> can
|
|
embed an optional text
|
|
between the tag name and the closing marker "-->". This text is intended
|
|
for readability only and completely ignored by the template parser.
|
|
For example: <code><!-- /TMPL_LOOP rows --></code><p><li>The </li><code>TMPL_ELIF</code> tag was introduced to allow
|
|
a more concise code. In full, now the "if" pattern looks like:
|
|
<pre class="samp">
|
|
!-- TMPL_IF condition_1 --
|
|
text_1
|
|
!-- TMPL_ELIF condition_2 --
|
|
text_2
|
|
...
|
|
!-- TMPL_ELSE --
|
|
text_else
|
|
!-- /TMPL_IF --
|
|
