Creating multiple Tiddlers by iterating through a variable...

[Jan]

Hello,
I want to create multiple Tiddlers in the background, which shall later
on be used for a slideshow. They shall contain text created with a
variant of Thomas` extract Macro
http://tid.li/tw5/numbers.html#%24%3A%2F_telmiger%2Fslice (Here
<<slicetext>>) and have the numbered titles $:temp/Slide/$(number)$.
I would like to extract the text of the $(number)$ 1 to 10 if it has a
slice (<sli1>slicetext</sli1>) marked .
I do not know how to perform an iteration in Wikitext ... and
unfortunately there seems to be something else which is wrong because it
does not work with a number and a given Tiddler instead of variables either.

Here is a link to my experiment:
SlidesNStories.tiddlyspot.com#slidesfromslices:slidesfromslices%20SourceTiddler

\define nextsl() -->defines the Tiddler to extract from
<$list
filter='[list[$:/StoryList]after{$:/HistoryList!!current-tiddler}[search:text[sli1]]'>{{!!title}}</$list>
\end
\define slicetext(number)
<<slice $(next)$ $(number)$>>
\end


<$button>
<$set name="next" value=<<nextsl>>>
<$set name="text" value=<<slicetext>>>
<$list filter='[title[$(next)$][search:text[sli$(number)$]]'>
<$fieldmangler>
<$action-setfield $tiddler="$:temp/Slide/$(number)$" text=$(text)$/>
</$fieldmangler>create slide tiddler 1
</$list>
</$set>
</$set>
</$button>

Thanks a lot for help.

Hi Jan,

just a quick hint from my phone: Is the link to your example working? Maybe you should update and expand the test content?

All the best!
Thomas

Hi Thomas,
You are right. Obviously updating didn't work. My internet is down to snailspeed at the moment. I will be able to update by Friday.You could copy the text into the nonexisting tiddler so long.

Best wishes
Jan

\define nextsl()

<$list
filter='[list[$:/StoryList]after{$:/HistoryList!!current-tiddler}[search:text[sli1]]'>{{!!title}}</$list>
\end
\define slicetext(number)
<<slice $(next)$ $(number)$>>
\end


<$button>
<$set name="next" value=<<nextsl>>>
<$set name="text" value=<<slicetext>>>
<$list filter='[title[$(next)$][search:text[sli$(number)$]]'>
<$fieldmangler>
<$action-setfield $tiddler="$:temp/Slide/$(number)$" text=$(text)$/>
</$fieldmangler>create slide tiddler 1
</$list>
</$set>
</$set>
</$button>

Hi Thomas, hi all...
I am still searching a way to create multiple Tiddlers by iterating different numbers to extract numbered slices from a tiddler.
At least I managed to update my TW so that you can see my experiment which is alas not working yet:
http://slidesnstories.tiddlyspot.com/#slidesfromslices:slidesfromslices%20SourceTiddler

Help is very Welcome

Best wishes Jan

Hi,
I am still looking for a way to create tiddlers that contain text
extracted from slices of a tiddler. (The aim is to build a slideshow
where big tiddlers can be divided into smaller slides.)
I managed to achieve most of it but one problem remains:
At the moment the macro (<<slicetext>>) is pasted into the field.
I would like to paste in the rendered value of the macro.

The link to the Test now works:

Thanks for Help
Jan


\define slidetitle()
$:/temp/Slide/$(number)$
\end
\define nextslide()
[list[$:/StoryList]after{$:/HistoryList!!current-tiddler}search:text[sli$(number)$]]'>
\end
\define slicetext()
<<slice $(sourcetitle)$ $(number)$>>
\end

<$button>
<$list filter='1 2' variable="number">
<$list filter=<<nextslide>> variable="sourcetitle">
<$action-setfield $tiddler=<<slidetitle>>
text=<<slicetext>>/>
</$list>
</$list>
create temporary slide Tiddlers from slices
