[tw5] Re: Lost in transclusion
Thanks so much, Eric and Tony. As usal, this was extremely helpful. And
<$wikify> actually solved the issue.
In fact, I was assuming the transclusion chain had to do with it (hence the
thread title), I am just not literate enough in TW to draw the right
conclusions and find the remedies. But I keep on working at it.
Which brings me to another point: maybe I've overcomplicated things by
storing a transclusion in a tiddler where a pointer to an array index in
the JSON tiddler (i.e. a number) should have done the trick. But that's a
different story.
So, thanks again, guys, much appreciated.

[tw5] Re: Lost in transclusion
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 `<>` 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="<>">
use <> here where it is the wikified version, or pre-evaluated
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

The problem is that you are doing a "double transclusion". That is, the
value of <> retrieved via transclusion isn't the actual name of
the company as text, but rather a secondary transclusion from a JSON
tiddler (i.e., {{$:/data/CI/companyRegister##1/name}}). When you render
<>, TiddlyWiki automatically parses that transclusion and
displays the actual value. However, when you use search in the
filter, the value isn't parsed any further, and you are literally searching
for the transclusion syntax, not the actual company name as text.
To resolve this, use <$wikify> instead of <$set> to fetch theCompany value,
like this:
<$wikify name="theCompany" text={{$:/data/CI/activeDossier}}>
!<$vars tv-wikilinks=no><>
<$list filter="[!is[system]search]" >
<>
The $wikify gets the value from the activeDossier tiddler AND then also
parses that value, so the result is the desired text value from the
underlying $:/data/CI/companyRegister tiddler.
When you use it in the search filter, it's already fully
resolved to be the actual company name as text, so the search should work
as you intend.

It looks like you want to search the text, title, or tag field for the name
of a company?? Is that what you want? If you want to search in some
non-default field, then you need to specify that field in your search.

It might be as simple as needing to use triple quoting, in case your theCompanies have quote characters in them. But note that the filter [!is[system]search] refers to all tiddlers globally, not e.g the current tiddler if that is what you hope for. IF you want to test if theCompany !is[system] you must do e.g [!is[system]... etc. <:-) -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
