3 HTML::Template is an okay templating kit, but it lacks a lot of powerful
4 features and thus makes it rather hard to give an ikiwiki site a consistent
5 look. If you browse the templates provided in the tarball, you'll notice that
6 more than one of them contain the `<html>` tag, which is unnecessary.
8 Maybe it's just me, I also find HTML::Template cumbersome to use, due in part
9 to its use of capital letters.
11 Finally, the software seems unmaintained: the mailing list and searchable
13 <http://html-template.sourceforge.net/html_template.html#frequently%20asked%20questions>
14 are broken and the author has not replied to my query in months.
16 I would love to see ikiwiki use the [Template
17 Toolkit](http://template-toolkit.org/) as templating engine.
19 One major reason for TT is its use of slots, a concept I first encountered
20 with Zope Page Templates and never wanted to miss it again. Let me quickly
21 illustrate, using the HTML::Template syntax for simplicity. Traditionally,
22 templating is done with includes:
25 <TMPL_INCLUDE header> <TMPL_INCLUDE header>
26 this is page A this is page B
27 <TMPL_INCLUDE footer> <TMPL_INCLUDE footer>
29 This involves four pages, and if you mistype "footer" on page B,
30 it'll be broken in potentially subtle ways.
32 Now look at the approach with slots:
40 <TMPL_USE MainTemplate> <TMPL_USE MainTemplate>
41 <TMPL_FILL content> <TMPL_FILL content>
42 This is page A This is page B
43 </TMPL_FILL> </TMPL_FILL>
44 </TMPL_USE> </TMPL_USE>
46 As soon as you think about more structure pages with various slots
47 to fill, I am sure you can see the appeal of that approach. If not,
48 here is some more documentation: <http://wiki.zope.org/ZPT/METALSpecification11>
50 I would be glad to volunteer time to make this switch happen, such as rewrite
51 the templates. I'd prefer not having to touch Perl though...
56 Yes, Template::Toolkit is very powerful. But I think it's somehow overkill for a wiki. HTML::Template can keep things simple, though. --[weakish](http://weakish.int.eu.org/blog/)
58 I'd have to agree that Template::Toolkit is overkill and personally I'm not a fan, but it is very popular (there is even a book) and the new version (3) is alleged to be much more nimble than current version. --[[ajt]]
