I’ve read quicly the differents threads about TOC macro. I don’t think I’ve seen this question:
Is it possible to modifiy the title display in the TOC expandable macro to append a field to it ?
I have tiddlers named A, B, C and their code field set to 1, 1.1, 1.2… And would like to obtain :
1.A
…1.1 B
…1.2 C
The “title display” used by the toc macros is defined by the toc-caption macro in the $:/core/macros/toc shadow tiddler. To add your “code” field content to the display, you can create a custom definition of the toc-caption macro in the tiddler in which your <<toc-selective-expandable>> macro is invoked, like this:
\define toc-caption()
\whitespace trim
<span class="tc-toc-caption tc-tiny-gap-left">
<$set name="tv-wikilinks" value="no">
<$transclude field="code"/>
<$transclude field="caption"><$view field="title"/></$transclude>
</$set>
</span>
\end
<<toc-selective-expandable ... >>
Notes:
toc-caption is only applied to the tiddler in which it occurs, so it won’t affect any other uses of toc-* macros.enjoy,

small typo in my solution…
change this:
<$transclude field="code">
to
<$transclude field="code"/>

Hi Eric,
Can we say this overrides the main toc-caption macro? I mean something similar to overriding a method in a base class in OOP?
Yes. “Override” is an accurate term for this technique.
As presented here, the customized version of toc-caption is only applied within the tiddler in which it is defined, making it a “local override”. However, you could make it a “global override”, simply by tagging the tiddler with $:/tags/global.
