Direktiva template je poskytována modulem template.

The template directive allows wiki pages to be used as templates. These templates can be filled out and inserted into other pages in the wiki using the directive. The templates page lists templates that can be used with this directive.

The directive has an id parameter that identifies the template to use. The remaining parameters are used to fill out the template.

Example

[[!template  id=note text="""Tento text se vloží do mé poznámky."""]]

Příklad vyplní šablonu note, předá jí pole text se zadanou hodnotou a výsledek vloží do stránky.

Using a template

Generally, a value can include any markup that would be allowed in the wiki page outside the template. Triple-quoting the value even allows quotes to be included in it. Combined with multi-line quoted values, this allows for large chunks of marked up text to be embedded into a template:

    [[!template  id=foo name="Sally" color="green" age=8 notes="""
    * [[Charley]]'s sister.
    * "I want to be an astronaut when I grow up."
    * Really 8 and a half.
    """]]

Creating a template

The template is a regular wiki page, located in the templates/ subdirectory inside the source directory of the wiki.

Alternatively, templates can be stored in a directory outside the wiki, as files with the extension ".tmpl". By default, these are searched for in /usr/share/ikiwiki/templates, the templatedir setting can be used to make another directory be searched first. When referring to templates outside the wiki source directory, the "id" parameter is not interpreted as a pagespec, and you must include the full filename of the template page, including the ".tmpl" extension. E.g.:

[[!template  id=blogpost.tmpl]]

The template uses the syntax used by the HTML::Template perl module, which allows for some fairly complex things to be done. Consult its documentation for the full syntax, but all you really need to know are a few things:

• Each parameter you pass to the template directive will generate a template variable. There are also some pre-defined variables like PAGE and BASENAME.
• To insert the value of a variable, use <TMPL_VAR variable>. Wiki markup in the value will first be converted to html.
• To insert the raw value of a variable, with wiki markup not yet converted to html, use <TMPL_VAR raw_variable>.
• To make a block of text conditional on a variable being set use <TMPL_IF variable>text</TMPL_IF>.
• To use one block of text if a variable is set and a second if it's not, use <TMPL_IF variable>text<TMPL_ELSE>other text</TMPL_IF>

Here's a sample template:

    <span class="infobox">
    Name: [[<TMPL_VAR raw_name>]]<br />
    Age: <TMPL_VAR age><br />
    <TMPL_IF color>
    Favorite color: <TMPL_VAR color><br />
    <TMPL_ELSE>
    No favorite color.<br />
    </TMPL_IF>
    <TMPL_IF notes>
    <hr />
    <TMPL_VAR notes>
    </TMPL_IF>
    </span>

The filled out template will be formatted the same as the rest of the page that contains it, so you can include WikiLinks and all other forms of wiki markup in the template. Note though that such WikiLinks will not show up as backlinks to the page that uses the template.

Note the use of "raw_name" inside the WikiLink generator in the example above. This ensures that if the name contains something that might be mistaken for wiki markup, it's not converted to html before being processed as a WikiLink.
