All those and more can be done using HTML::Template::Expr.

>  Greetings!  In using HTML::Template I found somewhat limited by the lack of formatting ability in the template language itself.  While I recognize the need for a separation between coding and layout, I often found myself making duplicate copies of a value in different formats so that the layout people would have the version they need.  For example: sometimes they would want the value in all uppercase (for a section heading), and then again they want it in all lowercase, or sometimes they want just the first few words (to layout an article teaser).

The "FORMAT=some-value" attribute to the <TMPL_VAR> construct allows the designer to alter the format of the variable.  I implemented several built-in formatters, including:
