Folks,
A solution was found for this specific use case, before posting, but the
Question still could do with an answer
- Use the <<storyTiddler>> variable to find the "DisplayTiddler"
regardless of the number of transclusions.
A reoccurring confusion of mine occurs trying to implement the following
with a define rather than a set, is it possible?
<$set name="callingTiddler" value={{{ [<currentTiddler>] }}} >
1st: <br>
{{tiddlername||Second}}
</$set>
The value <<callingTiddler>> will be available in all nested transclusions.
The problem with this is you always need to close the set widget. This
means every time you edit or add something to the tiddler you have to make
sure changes that need it are inside the set.
Is there a way to
\define callingTiddler() something
to achieve the same result?
The problem is whatever you place in a macro definition gets evaluated when
its displayed not before
Of course I can use;
\define callingTiddler() actual tiddlername
With a literal tiddler name but then each tiddler needs a unique setting
and you can't "import variables", make it global or any other method I can
think of
*Why?*
- I really want an answer to support a range of methods
- You can see in the above the use of `{{tiddlername||Second}}`! here I
can transclude Second with tiddlername acting as a parameter for "Second"
to use, but I still want access to the callingTiddler in that transclusion
and other nested in "Second"
*I would love global a method to capture for subsequent use in
transclusions the current "Display Tiddler"/callingTiddler - ie the one on
the screen before transclusion, but as many of you know the currentTiddler
changes according to context so it can't be used.*
Note: I went looking in the tiddler $:/config/ui/ViewTemplate to see how I
may set a displayTiddler value only to find the variable storyTiddler which
is functionally what I need. Though it does nothing to help me define a
variable that will store the current tiddler indefinitely.
Regards
Tony
