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