Hi Tony,
You probably solved your issue since, but in case you didn't, I just wanted
to state for the record that it was a perfect job for the *subfilter*
operator:
\define transcludeTag() [<currentTiddler>addprefix[$:/autotag/transclude/]]
$:/autotag/transclude transcluding items tagged {{{
[subfilter<transcludeTag>] }}}<br/>
<$list filter="[subfilter<transcludeTag>tagging[]]"
variable="transcludeTiddler">
hi <<transcludeTiddler>> <$transclude tiddler=<<transcludeTiddler>>
mode=block />
</$list>
Since *subfilter* role is to plug filter strings into other filters, the
computation of the filter result is delayed until necessary, first to
display it thanks to the {{{}}} construct, then to feed it to the list
widget as part of its filter attribute.
However, this power may have a drawback if we are not cautious: since the
computation of [<currentTiddler>] is delayed, let's say you didn't give an
explicit variable name to the list widget, and rather wanted to rely on it
to set currentTiddler and pass it to its content:
\define transcludeTag() [<currentTiddler>addprefix[$:/autotag/transclude/]]
$:/autotag/transclude transcluding items tagged {{{
[subfilter<transcludeTag>] }}}<br/>
(outside the list widget, ''<$text text="[subfilter<transcludeTag>]"/>''
gives {{{ [subfilter<transcludeTag>] }}})<br/>
<$list filter="[subfilter<transcludeTag>tagging[]]">
hi <<currentTiddler>> <$transclude mode=block />
(inside the list widget, ''<$text text="[subfilter<transcludeTag>]"/>''
gives {{{ [subfilter<transcludeTag>] }}})
</$list>
Because the currentTiddler value changes when entering the list widget, so
does the value of any included filters that contain a reference to
currentTiddler.
Best,
