This -supports things like conditionals and loops in templates and is pretty easy -to learn. - -I aim to keep almost all html out of ikiwiki and in the templates. - -It ships with some basic templates which can be customised: - -* `templates/page.tmpl` - Used for displaying all regular wiki pages. -* `templates/misc.tmpl` - Generic template used for any page that doesn't - have a custom template. -* `templates/recentchanges.tmpl` - Used for the RecentChanges page. -* `templates/editpage.tmpl` - Create/edit page. -* `templates/passwordmail.tmpl` - Not a html template, this is used to - generate the mail with the user's password in it. -* `templates/rsspage.tmpl` - Used for generating rss feeds for [[blog]]s. -* `templates/inlinepage.tmpl - Used for adding a page inline in a blog - page. -* `templates/inlinepagetitle.tmpl - Used for listing a page inline in a blog - archive page. - -If you like, you can add these to further customise it: - -* `templates/signin.tmpl` - If it exists, it is used for customising the - layout of the SignIn form and all assciated forms. The misc.tmpl is - wrapped around this, so it should only be a template for the form. -* `templates/prefs.tmpl` - If it exists, it is used for customising the - layout of the Prefs form and all assciated forms. The misc.tmpl is - wrapped around this, so it should only be a template for the form. - -Note that the SignIn and Prefs forms are implemented using -CGI::FormBuilder, which interfaces to HTML::Template, so not all of it can -be customised with templates, although most of it can, by creating these -templates.

The template +is a regular wiki page, located in the `templates/` subdirectory inside +the source directory 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: + +* 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 ``. 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 ``. +* To make a block of text conditional on a variable being set use + `text`. +* To use one block of text if a variable is set and a second if it's not, + use `textother text` + +Here's a sample template: + + + Name: \[[]]
+ Age:
+ + Favorite color:
+ + No favorite color.
+ + +
+ + + + +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 [[ikiwiki/WikiLink]] generator. 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 +[[ikiwiki/WikiLink]].
