Hey, Tony —
The trouble in your case is that you're putting the formulas in quotes,
which makes TiddlyWiki treat them as strings. The experimental syntax for
attribute values is just *<tag attribute=(= 2+2 =) />* — no quotes outside
the mushroom brackets. Generally I use the formula-vars
<https://evanbalster.com/tiddlywiki/formulas.html#FormulaVarsWidget> widget
when I want to set one or more variables to formula-computed values. You
could use the vars widget with the new syntax for the same effect...
Be mindful of how you format the date strings, too (or use to_tw_date).
Things I'm thinking about right now:
- "if" and "else" widgets that work with formulas and switch their
content on and off.
- Functions to query transclusions/filters/variables with string
arguments
- eg. transclude(<<otherTiddler>>, "this-field")
- eg. filter("[range[1," & <<rangeMax>> & "]]")
- eg. variable("item" & <<index>>)
- Functions to grab transclusions/variables as raw text rather than
formula data.
- Might make the functions above do this, and add a "datum" function
that emulates the behavior of the direct syntax.
