TWiki Template System

Definition of the templates used to render all HTML pages displayed in TWiki

Overview

The new modular template system is more flexible, efficient, and easily updated than the old set-up, where each template is a complete HTML file. The new master template approach places common templates parts, like headers and footers, in one shared file. This simplifies the conversion of templates into XHTML format, and provides a more versatile solution for templates and for TWikiSkins.

Major changes from the previous template system

The main difference is that templates are now defined using variables to include template parts. You change one stored instance of a common element to update all occurrences. The new system:

Functional Specifications

New Template System by Example

Attached is an example of an oops base template oopsbase.tmpl and a example oops dialog oopstest.tmpl which is based on the base template. NOTE: This isn't the release version, just a quick, simple demo.

Base template oopsbase.tmpl

The first line declares the delimiter variable called "sep", used to separate multiple link items. The variable can be called anywhere by writing %TMPL:P{"sep"}%

%TMPL:DEF{"sep"}% | %TMPL:END%
<html>
<head>
  <title> %WIKITOOLNAME% . %WEB% . %TOPIC% %.TMPL:P{"titleaction"}%</title>
  <base href="%SCRIPTURL%/view%SCRIPTSUFFIX%/%WEB%/%TOPIC%">
  <meta name="robots" content="noindex">
</head>
<body bgcolor="#FFFFFF">
<table width="100%" border="0" cellpadding="3" cellspacing="0">
  <tr>
    <td bgcolor="%WEBBGCOLOR%" rowspan="2" valign="top" width="1%">
      <a href="%WIKIHOMEURL%">
      <img src="%PUBURLPATH%/wikiHome.gif" border="0"></a>
    </td>
    <td>
      <b>%WIKITOOLNAME% . %WEB% . </b><font size="+2">
      <B>%TOPIC%</b> %TMPL:P{"titleaction"}%</font>
    </td>
  </tr>
  <tr bgcolor="%WEBBGCOLOR%">
    <td colspan="2">
      %TMPL:P{"webaction"}%
    </td>
  </tr>
</table>
--- ++ %TMPL:P{"heading"}%
%TMPL:P{"message"}%
<table width="100%" border="0" cellpadding="3" cellspacing="0">
  <tr bgcolor="%WEBBGCOLOR%">
    <td valign="top">
      Topic <b>%TOPIC%</b> . {
        %TMPL:P{"topicaction"}%
      }
    </td>
  </tr>
</table>
</body>

Test template oopstest.tmpl

Each oops template basically just defines some variables and includes the base template that does the layout work.

%TMPL:DEF{"titleaction"}% (test =titleaction=) %TMPL:END%
%TMPL:DEF{"webaction"}% test =webaction= %TMPL:END%
%TMPL:DEF{"heading"}%
Test heading %TMPL:END%
%TMPL:DEF{"message"}%
Test =message=. Blah blah blah blah blah blah blah blah blah blah blah...

   * Some more blah blah blah blah blah blah blah blah blah blah...
   * Param1: %PARAM1%
   * Param2: %PARAM2%
   * Param3: %PARAM3%
   * Param4: %PARAM4%
%TMPL:END%
%TMPL:DEF{"topicaction"}%
Test =topicaction=:
[[%WEB%.%TOPIC%][OK]] %TMPL:P{"sep"}%
[[%TWIKIWEB%.TWikiRegistration][Register]] %TMPL:END%
%TMPL:INCLUDE{"oopsbase"}%

TWiki master template

All common template parts are defined in one master template, twiki.tmpl, that all other templates include.

Template variable: Defines:
%TMPL:DEF{"sep"}% "|" separator
%TMPL:DEF{"htmldoctype"}% Start of all HTML pages
%TMPL:DEF{"standardheader"}% Standard header (ex: view, index, seach)
%TMPL:DEF{"simpleheader"}% Simple header with reduced links (ex: edit, attach, oops)
%TMPL:DEF{"standardfooter"}% Footer, excluding revision and copyright parts
%TMPL:DEF{"oops"}% Skeleton of oops dialog

Example: oopspreview.tmpl template
%TMPL:INCLUDE{"twiki"}%
%TMPL:DEF{"titleaction"}% (oops) %TMPL:END%
%TMPL:DEF{"webaction"}% *Attention* %TMPL:END%
%TMPL:DEF{"heading"}% Topic is not saved yet %TMPL:END%
%TMPL:DEF{"message"}% Please go back in your browser and save the topic. %TMPL:END%
%TMPL:DEF{"topicaction"}%
%TMPL:END%
%TMPL:P{"oops"}%
