Hi All,
I'm building a goal tracker using two html elements: <progress> and <svg>,
the brilliant "rpn" macro by Thomas Elmiger and a simple "DaysDiff" macro
that I created myself (it returns the number of days elapsed from a given
date).
The <svg> HTML element moves along the x axis and shows the completion rate
(using the fields 'tracker_current_value' divided by 'tracker_target_value'
multiplied by 520 [px] as "520" is the width that amounts to "100%
completion"); the <svg> element moves in parallel to the <progress> element
that is measuring the time that's elapsed:
The relevant snippets of code:
<svg><text x=<<ProgressMark>> y=16 fill="red">▼</text></svg>
<progress value=<<some value>> max=<<max value>>></progress>
The problem that I have is that the <svg> element will not accept the
output value of the <<ProgressMark>> macro that I've defined ad-hoc in the
tiddler in order to calculate the position of the <svg> element in this way:
\define Proportion()
<$macrocall $name="rpn" a=$(currentVal)$ b=$(targetVal)$ operation="/">
\end
\define ProgressMark()
<$macrocall $name="rpn" a=<<Proportion>> b=520 operation="*">
\end
<$set name=currentVal value={{!!tracker_current_value}}>
<$set name=targetVal value={{!!tracker_target_value}}>
<svg> does accept the value if it's entered as <<SomeMacro 12345>> but not
when entered as <$macrocall...> or <<ProgressMark>> even though the
<<ProgressMark>> returns the correct value when used outside of the <svg>
element.
How can I process the result of the macro? Could I use <$wikify> perhaps?
If so, how? I've looked around this group and could not find a satisfactory
solution.
Thank you very much for any suggestions!
