Preface

Kwartz is the template system which realized the concept of 'Separation of Presentation Logic and Presentation Data (SoPL/PD).' SoPL/PD enables to use complex presentation logics without breaking HTML design at all.

There are several patterns which help you to separate presentation logic and presentation data well. These patterns are called 'Presentation Patterns.'

This document shows Presentation Patterns.

ChangeLog

2005-03-21
  • add text for Kwartz directives.
  • add subsubsection title for all patterns.
  • add 'supplement' subsubsection for 'Replace Element by Value Pattern'.


Replacement

Replace Element by Value Pattern

Description

You can replace the element with the value of a variable or an expression. This is named 'Replace Element by Value Pattern.'


Situation

This pattern is very useful to print out the value of a variable or an expression as text.


Example Code

Presentation Data:

Hello <span id="mark:user">World</span>!

Presentation Logic:

#user {
  plogic: {
    print(username);  // print value of variable 'username' instead of the element
  }
}

Output Script:

### for eRuby
Hello<%= username %>!

### for PHP
Hello<?php echo $username; ?>!

### for JSTL
Hello<c:out value="${username}" escapeXml="false"/>!

### for Velocity
Hello$!{username}!

Supplement

The following is an example to print content text as default value when value is null or empty. This examples is an combination of 'Replace Element by Value Pattern' and 'Delete Tag Pattern'.

Presentation Logic:

#user {
  plogic: {
    // Print out value of variable 'username'.
    // Print 'guest' as a default value when 'username' is null or empty string.
    if (username == empty) {
      @cont;           // print out content text
    } else {
      print(username); // print out value of variable
    }
  }
}


Replace Content by Value Pattern

Description

You can also replace only the content of the element in the same way. This is named 'Replace Content by Value Pattern.'


Situation

This pattern is used frequently because the situation to replace the content by value is very popular.


Example Code

Presentation Data:

<h1 id="mark:title">Example</h1>

Presentation Logic:

#title {
  plogic: {
    @stag;
    print(title);  // print value of a variable 'title' instead of content
    @etag;
  }
}

Output Script:

### for eRuby
<h1><%= title %></h1>

### for PHP
<h1><?php echo $title; ?></h1>

### for JSTL
<h1><c:out value="${title}" escapeXml="false"/></h1>

### for Velocity
<h1>$!{title}</h1>

Supplement

The 'Replace Content by Value Pattern' is to be described as the following in Kwartz.

Presentation Logic:

#title {
  value: title;  // print value of a variable 'title' instead of content
}

Kwartz Directive 'id="value:expression"' lets you to use this pattern without presentation logic file.

Presentation Data:

<h1 id="value:title">Example</h1>


Replace Element by Element Pattern

Description

You can replace the element by other element. This pattern is named 'Replace Element by Element Pattern.'


Situation

This pattern is very useful to reuse the element in other place.


Example Code

Presentation Data:

<div id="mark:links">
 <a href="/">HOME</a> | <a href="/doc">Document</a> | <a href="/faq">FAQ</a>
</div>

<p>Welcome to my Home Page!</p>

<div id="mark:links2">
  Home | Document | FAQ
</div>

Presentation Logic:

#links2 {
  plogic: {
    @element(links);  // replace the element 'links2' by the element 'links'
  }
}

@element(name) represents the element which is marked by id="mark:name" or id="name".

Output Script:

<div>
 <a href="/">HOME</a> | <a href="/doc">Document</a> | <a href="/faq">FAQ</a>
</div>

<p>Welcome to my Home Page!</p>

<div>
 <a href="/">HOME</a> | <a href="/doc">Document</a> | <a href="/faq">FAQ</a>
</div>

Supplement

Directive 'id="replace:name"' lets you to use this pattern without presentation logic file.

<div id="mark:links">
 <a href="/">HOME</a> | <a href="/doc">Document</a> | <a href="/faq">FAQ</a>
</div>

<p>Welcome to my Home Page!</p>

<div id="replace:links">
  Home | Document | FAQ
</div>

The command-line option '-i file,file2,...' enables you to use elements which are described in other files.

Presentation Data(links.html):

<div id="mark:links">
 <a href="/">HOME</a> | <a href="/doc">Document</a> | <a href="/faq">FAQ</a>
</div>

Presentation Data(page.html):

<div id="mark:links1"> Home | Document | FAQ </div>

<p>Welcome to my Home Page!</p>

<div id="mark:links2"> Home | Document | FAQ </div>

Presentation Logic(page.plogic):

#links1 {
  plogic: {
    @element(links);
  }
}
#links2 {
  plogic: {
    @element(links);
  }
}

Compile:

$ kwartz -l eruby -i links.html -p page.plogic page.html

Output Script:

<div>
 <a href="/">HOME</a> | <a href="/doc">Document</a> | <a href="/faq">FAQ</a>
</div>

<p>Welcome to my Home Page!</p>

<div>
 <a href="/">HOME</a> | <a href="/doc">Document</a> | <a href="/faq">FAQ</a>
</div>


Replace Content by Element Pattern

Description

You can replace content of an element by other element. This pattern is named 'Replace Content by Element Pattern' or 'Placeholder Pattern.'


Situation

This pattern is very useful to separate contents data and design layout into separate files.


Example Code

The following example contains four files.

Presentation Data(contents.html):

<html>
  <body>
    
    <p>menu:</p>
    <ul id="mark:menu">
      <li><a href="..." id="mark:menu_item">menu1</a></li>
    </ul>

    <p>article:</p>
    <div id="mark:article">
      <h2>What is Kwartz?</h2>
      <p>Kwartz is a template system, which realized the
         concept <strong>`Separation of Presentation Logic
         and Presentation Data'(SoPL/PD)</strong>.
      </p>
    </div>
    
  </body>
</html>

Presentation Logic(contents.plogic):

#menu {
  plogic: {
    @stag;
    foreach (item in menu_list) {
      @cont;
    }
    @etag;
  }
}

#menu_item {
  value: item['name'];
  attr:  "href" item['url'];
}

Presentation Data(layout.html):

<!doctype html public "-//W3C//DTD HTML 4.01 Transitional//EN">
<html lang="en">
  <head>
    <title id="value:title">...title...</title>
    <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

      </tr>
    </table>
    
  </body>
</html>

Presentation Logic(layout.plogic):

#placeholder_menu {
  plogic: {
    @stag;
    @element(menu);   // replace content by other element
    @etag;
 }
}

#placeholder_article {
  plogic: {
    @stag;
    @element(article);   // replace content by other element
    @etag;
  }
}

Compilation requires the command-line option -i file1,file2,... which enables to import elements defined in other files.

Compile:

$ kwartz -l eruby  -i contents.html -p contens.plogic,layout.plogic layout.html

Output Script:

             :



Deletion

Delete Element Pattern

Description

If presentation logic is empty, the element is not printed out. This pattern is named 'Delete Element Pattern' or 'Dummy Element Pattern.'


Situation

This pattern enables you to use dummy data in presentation data.


Example Code

Presentation Data:

<ul>
  <li>foo</li>
  <li id="dummy">bar</li>
</ul>

Presentation Logic:

#dummy {
  plogic: {
    // empty
  }
}

Presentation Data:

<ul>
  <li>foo</li>
  <li id="dummy:d1">bar</li>
</ul>


Delete Tag Pattern

Description

If you use only @cont and don't use @stag and @cont, you can remove start and end tags of the element. This pattern is named 'Delete Tag Pattern' or 'Dummy Tag Pattern.'


Situation

This pattern is very useful if you want to print tags according to condition.


Example Code

Presentation Data:

<a href="..." id="mark:next">Next</a>

Presentation Logic:

#next {
  attr: "href" url;
  plogic: {
    if (url == null) {
      @cont;   // don't print tags when url is null
    } else {
      @stag;
      @cont;
      @etag;
    }
  }
}

Output Script:

### for eRuby
<% if url == nil then %>
Next<% else %>
<a href="<%= url %>">Next</a>
<% end %>

### for PHP
<?php if ($url == NULL) { ?>
Next<?php } else { ?>
<a href="<?php echo $url; ?>">Next</a>
<?php } ?>

### for JSTL
<c:choose><c:when test="${url eq null}">
Next</c:when><c:otherwise>
<a href="<c:out value="${url}" escapeXml="false"/>">Next</a>
</c:otherwise></c:choose>

### for Velocity
#if($url)
Next#else
<a href="$!{url}">Next</a>
#end



Iteration

Iterate Element Pattern

Description

Iteration which contains @stag, @cont, and @etag represents to iterate the element. This pattern is named 'Iterate Element' pattern.


Situation

The situation is very popular which requres to print list items. This pattern is very useful for all these situations.


Example Code

Presentation Data:

<table>
  <tr id="mark:items">
   <td>@{item}@</td>
  </tr>
</table>

Presentation Logic:

#items {
  plogic: {
    // iterate start tag, content, and end tag
    foreach (item in list) {
      @stag;
      @cont;
      @etag;
    }
  }
}

Output Script:

### for eRuby
<ul>
<% for item in list do %>
  <dt><%= item.text %></dt>
  <dd><%= item.desc %></dd>
<% end %>
</ul>

### for PHP
<ul>
<?php foreach ($list as $item) { ?>
  <dt><?php echo $item->text; ?></dt>
  <dd><?php echo $item->desc; ?></dd>
<?php } ?>
</ul>

### for JSTL
<ul>
<c:forEach var="item" items="${list}">
  <dt><c:out value="${item.text}" escapeXml="false"/></dt>
  <dd><c:out value="${item.desc}" escapeXml="false"/></dd>
</c:forEach>
</ul>

### for Velocity
<ul>
#foreach($item in $list)
  <dt>$!{item.text}</dt>
  <dd>$!{item.desc}</dd>
#end
</ul>

Supplement

Kwartz directive id="foreach:item=list" lets you to use this pattern without presentation logic file.

Presentation Data:

<table>
  <tr id="foreach:item=list">
   <td>@{item}@</td>
  </tr>
</table>


Iterate Content Pattern

Description

Iteration which contains only @cont represents to iterate the content. This pattern is named 'Iterate Content' pattern.


Situation

This pattern is very useful when creating <dl></dl> list or table which repeats several rows.


Example Code

Presentation Data:

<ul id="mark:items">
  <dt>@{item.text}@</dt>
  <dd>@{item.desc}@</dd>
</ul>

Presentation Logic:

#items {

    @stag;
    foreach (item in list) {
      @cont;
    }
    @etag;
  }
}

Output Script:

<ul id="loop:item=list">
  <dt>@{item.text}@</dt>
  <dd>@{item.desc}@</dd>
</ul>



Selection

Select Element Pattern

Description

The following is an example to choose a certain element from some elements. This pattern is named 'Select Element Pattern.'


Situation

This pattern is very useful when you want to change data according to conditions.


Example Code

Presentation Data:

<div id="mark:message">
  <font color="red"   id="mark:error">ERROR!</font>
  <font color="blue"  id="mark:warning">Warning:</font>
  <font color="black" id="mark:good">No error.</font>
</div>

Presentation Logic:

#message {
  plogic: {
    if (status == 'error') {
      @element(error);      // ERROR!
    } else if (status == 'warning') {
      @element(warning);    // Warning:
    } else {
      @element(good);       // No error.
    }
  }
}

Output Script:

### for eRuby
<% if status == "error" then %>
  <font color="red">ERROR!</font>
<% elsif status == "warning" then %>
  <font color="blue">Warning:</font>
<% else %>
  <font color="black">No error.</font>
<% end %>

### for PHP

  <font color="red">ERROR!</font>
<?php } elseif ($status == "warning") { ?>
  <font color="blue">Warning:</font>
<?php } else { ?>
  <font color="black">No error.</font>
<?php } ?>

### for JSTL
<c:choose><c:when test="${status eq 'error'}">
  <font color="red">ERROR!</font>
</c:when><c:when test="${status eq 'warning'}">
  <font color="blue">Warning:</font>
</c:when><c:otherwise>
  <font color="black">No error.</font>
</c:otherwise></c:choose>

### for Velocity
#if($status == "error")
  <font color="red">ERROR!</font>
#elseif($status == "warning")
  <font color="blue">Warning:</font>
#else
  <font color="black">No error.</font>
#end

Supplement

Kwartz directive 'id="if:condition"', 'id="elseif:condition"', and 'id="else:"' let you to use this pattern without presentation logic file.

Presentation Data:

<div>
  <font color="red"   id="if:status=='error'">ERROR!</font>
  <font color="blue"  id="elseif:status=='warning'">Warning:</font>
  <font color="black" id="else">No error.</font>
</div>


Pick-up Element Pattern

Description

If you want to use certain elemnts, do marking the elements and use only them in presentation logic. Elements which are not marked are ignored and not printed. This pattern is named 'Pick-up Element Pattern.'

'Pick-up Element' pattern is opposite of 'Dummy Element' pattern. In 'Dummy Element' pattern, dummy elements are marked and removed so that necessary elements are leaved. In 'Pick-up Element' pattern, necessary elements are marked and leaved so that dummy elements are removed.


Situation

This pattern is useful when many dummy datas are exist.


Example Code

Presentation Data:

<html>
  <body>
    <div id="breadcrumbs">
      <a href="@{item['path']}@" id="mark:crumb">@{item['name']}@</a>
      <span id="mark:separator">&gt;</span>
      <a href="/aaa/">AAA</a> &lt;
      <a href="/aaa/bbb/">BBB</a> &lgt;
      <a href="/aaa/bbb/ccc">CCC</a> &lgt;
      <b id="mark:title">@{title}@</b>
    </div>
  </body>
</html>

Presentation Logic:

#breadcrumbs {
  plogic: {
    foreach (item in list) {
      @element(crumb);          // print <a>...</a>
      @element(separator);      // print '&gt;'
    }
    @element(title);            // print <b>title</b>
  }
}

Output Script:

### for eRuby
<html>
  <body>
<% for item in list do %>
      <a href="<%= item["path"] %>"><%= item["name"] %></a>
      &gt;
<% end %>
      <b><%= title %></b>
  </body>
</html>

### for PHP
<html>
  <body>
<?php foreach ($list as $item) { ?>
      <a href="<?php echo $item["path"]; ?>"><?php echo $item["name"]; ?></a>
      &gt;
<?php } ?>
      <b><?php echo $title; ?></b>
  </body>
</html>

### for JSTL
<html>
  <body>
<c:forEach var="item" items="${list}">
      <a href="<c:out value="${item['path']}" escapeXml="false"/>"><c:out value="${item['name']}" escapeXml="false"/></a>
      &gt;
</c:forEach>
      <b><c:out value="${title}" escapeXml="false"/></b>
  </body>
</html>

### for Velocity
<html>
  <body>
#foreach($item in $list)
      <a href="$!{item["path"]}">$!{item["name"]}</a>
      &gt;
#end
      <b>$!{title}</b>
  </body>
</html>

The above example should be described as following.

Presentation Data:

<html>
  <body>
    <div id="breadcrumbs">
      <a href="/" id="mark:crumb">Home</a>
      <span id="mark:separator">&gt;</span>
      <a href="/aaa/">AAA</a> &lt;
      <a href="/aaa/bbb/">BBB</a> &lgt;
      <a href="/aaa/bbb/ccc">CCC</a> &lgt;
      <b id="mark:title">Page Title</b>
    </div>
  </body>
</html>

Presentation Logic:

#breadcrumbs {
  plogic: {
    foreach (item in list) {
      @element(crumb);          // print <a>...</a>
      @element(separator);      // print '&gt;'
    }
    @element(title);            // print <b>title</b>
  }
}
#crumb {
  value: item['name'];
  attr:  "href" item['path'];
}
#title {
  value: title;
}


Extract Element Pattern

Description

It is able to extract a certain element form the whole presentation data. Other element and text strings are not printed. This pattern is named 'Extract Element Pattern.'


Situation

This pattern is very useful to extract HTML fragments and make them libraries.


Example Code

The following is an example to extract the HTML fragments 'tablist', 'menulist', and 'copyright' and generates the output scripts for them.

Presentation Data (design.html):

<html id="mark:whole">
  <head>
    <title>Design Examples</title>
    <link rel="stylesheet" href="design.css" type="text/css">
  </head>
  <body>

    <div id="mark:tablist">
      <div class="tabs" id="mark:tabs">
        <a href="/" class="" id="mark:tab">Home</a>
        <a href="/product/" class="selected">Product</a>
        <a href="/download/" class="">Download</a>
        <a href="/support/" class="">Support</a>
      </div>
      <div class="tabsline">
      </div>
    </div>

    <br>

    <div id="mark:menulist">
      <span class="menu_title" id="value:menu_title">MenuList</span>
      <div class="menus" id="mark:menus">
        <a href="/cgi-bin/email.cgi" class="" id="mark:menu">E-Mail</a>
