Hello, Tony —
Assuming you have both the formula plugin *and* the attribute-modules
plugin installed, un-quoting your attributes will make them into formulas
(instead of literal strings):
\define showtodayrange(datefield1,datefield2)
<progress
value=(= days( date( {{!!$datefield1$}} ) , now() ) =)
max=(= days( date( {{!!$datefield1$}} ) , date( {{!!$datefield2$}} ))
=)/>
\end
The attribute-modules plugin is really just a stand-in for my core pull
request, and the "safer" way to do this is to use the <<formula ...>> macro
instead of the direct syntax. In this case you do quote the formula, but
you don't include the mushroom brackets:
\define showtodayrange(datefield1,datefield2)
<progress
value=<<formula "days( date( {{!!$datefield1$}} ) , now() )">>
max=<<formula "days( date( {{!!$datefield1$}} ) , date(
{{!!$datefield2$}} ))">>/>
\end
Gets me thinking about how I'd like to add some more tiddlywiki-oriented
functions like transclude(tiddlerName, fieldName) and
filter(expressionString) to formulas...
