buid a tree

[Rustem]

I have a macro that outputs a tree of tiddlers, but it only works when invoked from the “root node” tiddler. If I put it in a tiddler with a different name, there is no tree. Basically, the parameter is ignored, it just picks up the current tiddler’s title and goes from there.

I spent all day trying to make it work from any tiddler, to no avail. I looked at the “toc” macros, but wasn’t able to adapt them. I just need a simple tree. I cannot use one of the “toc” macros - unlike “toc”, mine doesn’t go into infinite recursion when a tiddler is tagged with itself.

Please help! Thanks!

\define tree_macro(node)
;[[$node$]]
:<$list filter="[<currentTiddler>tagging[]!<currentTiddler>]">

  <$macrocall $name=tree_macro node={{!!title}}/>

</$list>
\end

-R.

Use the <$tiddler> widget to set the context for the initial node, like this:

\define tree_macro(node)
<$tiddler tiddler="$node$">

;[[$node$]]
:<$list filter="[<currentTiddler>tagging[]!<currentTiddler>]">

  <$macrocall $name=tree_macro node={{!!title}}/>

<

/$list>
</$tiddler>
\end

enjoy,
