With this plugin, you can set up templates, and cause them to be filled out
and inserted into pages in the wiki. Using a template works like this:
\[[template id=foo name="Charley" color="red" age=11]]
This fills out the template templates/foo, filling in the color and age
fields on it with the specified values, and inserts the result into the page.
(Note that if the template doesn't exist, the page will provide a link that
can be used to create it.)
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.
"""]]
To create a template, make a page in the wiki named template/foo. Note
that this is a different location than the directory used for the
[[templates]] used to build the wiki itself, which is not part of the wiki.
The template uses the syntax used by the [[cpan 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:
- To insert the value of a variable, use
<TMPL_VAR variable>.
- To make a block of text conditional on a variable being set use
<TMPL_IF NAME="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 NAME="variable">text<TMPL_ELSE>other text</TMPL_IF>
Here's a sample template:
<span class="infobox">
Name: <TMPL_VAR name><br />
Age: <TMPL_VAR age><br />
<TMPL_IF NAME="color">
Favorite color: <TMPL_VAR color><br />
<TMPL_ELSE>
No favorite color.<br />
</TMPL_IF>
<TMPL_IF NAME="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.
