4 else="This wiki has templates **disabled**."
7 Templates are files that can be filled out and inserted into pages in the
10 [[!if test="enabled(template) and enabled(inline)" then="""
12 ## Available templates
14 These templates are available for inclusion onto other pages in this
17 [[!inline pages="templates/* and !*/discussion" feeds=no archive=yes
18 sort=title template=titlepage]]
23 Using a template works like this:
25 \[[!template id=note text="""Here is the text to insert into my note."""]]
27 This fills out the [[note]] template, filling in the `text` field with
28 the specified value, and inserts the result into the page.
30 Generally, a value can include any markup that would be allowed in the wiki
31 page outside the template. Triple-quoting the value even allows quotes to
32 be included in it. Combined with multi-line quoted values, this allows for
33 large chunks of marked up text to be embedded into a template:
35 \[[!template id=foo name="Sally" color="green" age=8 notes="""
36 * \[[Charley]]'s sister.
37 * "I want to be an astronaut when I grow up."
38 * Really 8 and a half.
41 ## Creating a template
43 To create a template, simply add a template directive to a page, and the
44 page will provide a link that can be used to create the template. The template
45 is a regular wiki page, located in the `templates/` subdirectory inside
46 the source directory of the wiki.
48 The template uses the syntax used by the [[!cpan HTML::Template]] perl
49 module, which allows for some fairly complex things to be done. Consult its
50 documentation for the full syntax, but all you really need to know are a
53 * Each parameter you pass to the template directive will generate a
54 template variable. There are also some pre-defined variables like PAGE
56 * To insert the value of a variable, use `<TMPL_VAR variable>`. Wiki markup
57 in the value will first be converted to html.
58 * To insert the raw value of a variable, with wiki markup not yet converted
59 to html, use `<TMPL_VAR raw_variable>`.
60 * To make a block of text conditional on a variable being set use
61 `<TMPL_IF NAME="variable">text</TMPL_IF>`.
62 * To use one block of text if a variable is set and a second if it's not,
63 use `<TMPL_IF NAME="variable">text<TMPL_ELSE>other text</TMPL_IF>`
65 Here's a sample template:
67 <span class="infobox">
68 Name: [[<TMPL_VAR raw_name>]]<br />
69 Age: <TMPL_VAR age><br />
70 <TMPL_IF NAME="color">
71 Favorite color: <TMPL_VAR color><br />
73 No favorite color.<br />
75 <TMPL_IF NAME="notes">
81 The filled out template will be formatted the same as the rest of the page
82 that contains it, so you can include WikiLinks and all other forms of wiki
83 markup in the template. Note though that such WikiLinks will not show up as
84 backlinks to the page that uses the template.
86 Note the use of "raw_name" inside the [[WikiLink]] generator. This ensures
87 that if the name contains something that might be mistaken for wiki markup,
88 it's not converted to html before being processed as a [[WikiLink]].
