Re: [htmltmpl] FORMAT= enhancement to <TMPL_VAR> construct

yes - but the question was whether this type of functionality was =
suitable to be added as a native capability.

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).

translation of HTML::Template found at =
http://vlib.activefish.com/docs/vlibTemplate.html.  The =
"FORMAT=3Dsome-value" attribute to the <TMPL_VAR> construct allows the =
designer to alter the format of the variable.  I implemented several =
built-in formatters, including:

each word

> >  FORMAT=3D#w  --  output the first # words of the value
> >  FORMAT=3D#l  --  output the first # lines of the value

declared in the 'formatters' hash when the template object was new'ed
