I have the ExternalTiddlerPlugin installed. I'm trying to get the
tiddler macro to evaluate the contents of a separate tiddler in order
to determine what tiddler will be imported. Here's what I have tried
so far:

 <<tiddler    {{"return store.getTiddlerSlice('PagePick','page')+'#3'
"}} >>
 <<tiddler  {{"store.getTiddlerSlice('PagePick','page')+'#3' ; "}} >>
 <<tiddler  [[PagePick::page]]#3  >>

I've tried other versions. None of these have worked so far. As a
check, I ran the script:

<script>
return store.getTiddlerSlice('PagePick','page')+'#3'  ;
</script>

and it returns the correct response:
  killthis.html#3

And yes, "killthis.html" exists in the same directory, and has a
tiddler called "3".

In fact, I can do exactly what I want if I construct the macro on the
fly like:

<script>
return "<<tiddler " + store.getTiddlerSlice('PagePick','page')+'#3'  +
" >>" ;
</script>

But somehow that seems clumsier than it ought to be.

Thanks in advance,
Mark

You were very close!

The use of the trailing '' in the above code snippet forces the result
to be a blank string so that the computed parameter can evaluated
*without* producing any macro output, as a way to invoke tiny bits of
javascript without using InlineJavascriptPlugin. However, for your
purposes, you *do* want to produce output from the <<tiddler>> macro,
so you need to get rid of the trailing '' in order for the correct
param value to be applied.  Thus:

<<tiddler  {{"store.getTiddlerSlice('PagePick','page')+'#3'}} >>

enjoy,
-e

errata:

there was an extra leading quote that needed to be removed as well...
thus:

<<tiddler  {{store.getTiddlerSlice('PagePick','page')+'#3'}}>>

-e

Hi Eric,

Thanks for the help! I think what you're saying is that if there is
any space in the input scriptlet, then the parser will think you are
starting a new parameter and discard the previous one as incomplete.
Or?

Now that I have it working, I realize that the ExternalTiddlerPlugin
doesn't seem to allow me to dive down one directory, with a relative
path like this:

  <<tiddler directory/targetfile.html#1 >>

or with any other path I've tried. Is this a typical safety protocol,
or is there some formulation of path that will allow this to happen?

Many thanks again!
Mark
