Filter using toc?

[Steven Schneider]

I figure this must be possible, but can't quite get it to work.

How would I write a filter that would list all tiddlers listed with <<toc "TableOfContents">>?

Thanks,

Hi Steven,

I once made one:

$:/core/modules/filters/toc.js

1. wasn't considered useful for the core.
   
2. needs some more polishing to prevent recursion
   
• right now it doesn't, so you may hit an infinite loop
3. will publish as a plugin.
   
4. will reconsider options, since in the end I want to be able to define:
• the tag (falls back to currentTiddler)
• the max level to go down to
• a filter of titles to exclude (and not further look for children)
• a filter of titles to truncate (and not further look for children)
• they are in the results

Best wishes,

Tobias.

I'm not sure, what you want to achieve. ... The toc macro is a "relatively" straight forward recursive macro, that creates a structure using ordered lists. So changing this behaviour, to create a simple list, should be possible.

If you want to print out a dynamically generated filter, that's used to create the toc, this should be possible too. .. But the result will be super ugly and barely readable for humans. We have to deal with "infinite recursion protection", which makes the filter ugly.

Can you clarify the usecase a bit?

You could use this filter.
just add more 'tagging[]' operator if you have larger toc

<$list filter="
[[TableOfContents]]
[[TableOfContents]tagging[]]
[[TableOfContents]tagging[]tagging[]]
[[TableOfContents]tagging[]tagging[]tagging[]]
[[TableOfContents]tagging[]tagging[]tagging[]tagging[]]
[[TableOfContents]tagging[]tagging[]tagging[]tagging[]tagging[]]
">
<$link>{{!!title}}</$link><br>
</$list>

Hi Mario,

 

I'm not sure, what you want to achieve

One useful thing could be a searchable index of everything in a toc.

Another useful thing would be to able to page through a toc as if a book.

Best wishes,

Thanks, Tobias, This is great. I'm using it in various ways all the time these days. It's an interesting way to slice into a wiki - through toc.
