Here's a little macro that will "walk" a TOC tree of any depth and return a
flat list of tiddler titles, in the order they occur in the TOC:
\define toc-list(here,exclude,max,level:"1")
<$list filter="""[tag[$here$]] $exclude$ -[[$here$]]""">
<$text text="[["/><<currentTiddler>><$text text="]]"/><br>
<$reveal default="$level$" type="nomatch" text="$max$">
<$macrocall $name="toc-list" here=<<currentTiddler>> max="$max$"
exclude="""$exclude$ -[[$here$]]""" level={{{ [[$level$]add[1]] }}}/>
</$reveal>
</$list>
\end
To see the list, starting with a top-level of tiddlers tagged with
"Contents", simply write:
<<toc-list here:"Contents">>
* The "exclude" param is automatically calculated internally to prevent
infinite recursion if there are any circular references. It can also be
provided as an explicit input parameter in the macro call to prevent
specific branches of the tree from being traversed.
* The "max" param is optional and limits the depth of traversal. It works
with the "level" param which is calculated internally to track how deep the
traversal has gone.
Thus, if you want to get a list that excludes tiddler tagged as "Task", you
could write:
<<toc-list here:"Contents" exclude:"Task">>
and if you want to limit the depth to 3, you could write:
<<toc-list here:"Contents" max:"3">>
Of course, this is only the first step in the process of exporting the
tiddlers, but it does produce a list in the correct order. The remaining
task is to use this result as input to an export process.
For example, you could produce this list in a tiddler, and then -- as Saq
has already suggested, simply copy/paste the result into the
$:/AdvancedSearch Filter input field. Then press the "export" button and
choose "static HTML".
It should also be possible to automate those steps so you can just press a
button and get the desired output with one click. I'll fiddle about a bit
and see if I can provide a simple bit of button/action syntax that does
this. Right now I'm not feeling very well, so it will have to wait a bit
for me to get some rest.
