Often the template page contains a simple skeleton for a particular type of
- page. For the bug report pages in the above example, it might look
- something like:
+ page, wrapped in a [[templatebody]] directive. For the bug report pages in
+ the above example, it might look something like:
+ \[[!templatebody <<ENDBODY
Package:
Version:
Reproducible: y/n
Details:
+ ENDBODY]]
The template page can also contain [[!cpan HTML::Template]] directives,
-like other ikiwiki [[templates]]. Currently only one variable is
-set: `<TMPL_VAR name>` is replaced with the name of the page being
-created.
+like other ikiwiki [[templates]].
+
+These variables might be set:
+
+* `<TMPL_VAR name>` is replaced with the name of the page being
+ created.
+
+* `<TMPL_VAR uuid>` is replaced with a version 4 (random) UUID
+ suitable for use in `\[[!meta guid="urn:uuid:<TMPL_VAR uuid>"]]`.
+ (Requires the `UUID::Tiny` Perl module if not running on Linux.)
+
+* `<TMPL_VAR time>` is replaced with the current (template generation)
+ time using a fixed format (RFC 3339, `%Y-%m-%dT%H:%M:%SZ`),
+ suitable for use in `\[[!meta date="<TMPL_VAR time>"]]`
+ (see [[meta]]) or `\[[!date "<TMPL_VAR time>"]]` (see [[date]]).
+ Text outside the [[templatebody]] directive is not part of the template,
+ and can be used to document it.
+
+ If the template does not contain a [[templatebody]] directive, the entire
+ source of the page is used for the template. This is deprecated.
