Okay, I'm trying my best to not make this long-winded. My use case is as
follows...
I'm writing a documentation TW for an app. It has logical *chapters* and
*sections* within chapters called *chapsec*s (*1 chapsec* = 1 tiddler).
I'm trying to take the approach that the system will be a good authoring
tool for... well, authoring anything "book-like".
Within *chapsec* tiddlers, I use annotations macros to annotate the text.
Annotations can be enabled (made visible) and disabled (made invisible)
globally. The annotation macro is named *bk-ann*.
What I'd like to do is, for each *chapsec*, find all *bk-ann*s in the text
field and list their content. An example might be...
<<bk-ann "Explain the use of the Tiddlywiki's macro
system">>
and
<<bk-ann "Explain the scope rules of Tiddlywiki
macros">>
As you can see, this text could become a synopsis of each *chapsec* if I
could figure out a way to re-use the annotation text. The output would
render:
* Section 1-010 synopsis:*
* Explain the use of the Tiddlywiki's macro system Explain the scope
rules of Tiddlywiki macros*
I'm guessing we're not quite there yet? But hoping I'm wrong :)
