Werner,
I am confident Eric is spot on. It was the correct understanding of this
issue and the use of wikify that stopped me getting stuck regularly. I have
being trying to get some activity on this because it is a barrier to new
users. Perhaps this quick note will help as a rule until you fully
understand it.
- If you need a value to be "evaluated" from wikitext to use within
subsequent Wikitext logic use the wikify widget at the last possible moment.
- This guide suggests trying to use wikify in external macros is a
path to disappointment
- Make sure you close the wikify appropriately (as with all other
widgets) or unusual and broken result will occur
- Its only at the final render of the tiddler that all things are
wikified automatically so a standalone `<<varormacro>>` appears to produce
the result you want, but as Eric said the result inside the wikitext
(before evaluation) without wikification it is not evaluated at that point.
- It is fine to use the same name when wikifying to stop code complexity
\define macroname() blah blah
<$wikify name=macroname text="<<macroname>>">
use <<macroname>> here where it is the wikified version, or pre-evaluated
</$wikify>
In closing
- If some of our community developers see this what would be better is
something like the following;
- Allow any variable to be referenced in its "evaluated state" eg
((macroname)) would effectively wikify inline
- Automatically wikify/evaluate variables or macros when used in
filters and other appropriate places.
Regards
Tones
