Thanks for the idea, BJ. Unfortunately, it doesn't seem to work.
When I invoke <<mymacro>> (as below), nothing happens (just a few empty
lines are entered). But when I change the x value from x=$ProgressMark$ to,
say, x=50 (or any other number), the svg/text element is displayed and
moved as expected.
Below is the updated code. Is there any other way I could get
$ProgressMark$ evaluated?
\define Proportion()
<$macrocall $name="rpn" a=$(currentVal)$ b=$(targetVal)$ operation="/">
\end
\define ProgressMark()
<$macrocall $name="rpn" a=<<Proportion>> b=520 operation="*">
\end
\define mymacro(ProgressMark)
<svg><text x=$ProgressMark$ y=16 fill="red">▼</text></svg>
\end
<$set name=currentVal value={{!!tracker_current_value}}>
<$set name=targetVal value={{!!tracker_target_value}}>
<<mymacro>>
</$set>
Thank you again!
