Dear all, here's upgrade-troubleshooting post #3, with apologies if I
failed to find an existing answer...
The power of transcluded template tiddlers is enormous, and yet I'm
frustrated by what happens when any tiddler that *uses* such a template is
then itself shown within another tiddler (say, in a tab, or a table of
contents structure). For example...
I have a simple {{childtabs}} template, plus a {{childtabs-vert}} variant,
and one of these is transcluded at the bottom of most of my significant
tiddlers (replacing old ForEachTiddler function). It just presents a tab
for each "child" (= each tiddler tagged with the current tiddler's title).
I love how quick it is to pop that string into place; I also love that
tweaking the template makes the changes reverberate through all the
instances. Here's the current contents of that template:
<$set name="target" filter="[<storyTiddler>get[draft.of]] [<storyTiddler>
!has[draft.of]]">
<<tabs "[tag<target>]" {{!!title}} "$:/state/tabby">>
</$set>
What I really wish for is a variant that resolves "within" the lowest-level
tiddler in which it's most directly embedded. So, when I'm currently
reading a "grandparent"-level tiddler (like *units
<http://ethicsatwes.tiddlyspot.com/#units>*), each child-tab (including,
say, *Unit A*) should ideally render just as it would if it were called up
on its own, meaning it would show tabs for its own children (like
*Epictetus*), which then may have further children, etc. (using a mix of
horizontal and vertical tabs makes this surprisingly not too visually
noisy).
But as it is, trying to drill down (when the {{childtabs}} and
{{childtabs-vert}} templates are in use) shows either a tab set that simply
replicates the enclosing set, or a recursive transclusion error — which I
especially want to avoid in a teaching resource site! (Meanwhile, other
transclusions I'm using end up just showing nothing at all when the tiddler
they're part of is being rendered as a tab within a tiddler that doesn't
have the relevant fields.)
I realize I could explicitly spell out the rigid local tiddler title,
"baking in" each use of a template, but that seems to undermine the power
and simplicity of templates. Have others also wished for a tighter kind of
transclusion that clings to the narrowest enclosing context...? Is it
possible? Am I missing something obvious?
