Mat,
Believe it or not, I do know where you are coming from and I support a well
designed feature to achieve what you want. But I do urge caution. At
present a filter tends to generate a one many or no specific list of items.
The point I believe I am making is however there are already quite elegant
methods to achieve what you ask.
- In the case of your example using the get, is asking for the content
of that field on every tiddler to become the list, you are getting what you
ask for,
- and this feature is often needed.
- But no, in fact you are asking for the tiddler name and the content of
a field.
The way I would answer this would be a number of ways, but with two
possible examples below
<$list filter="[tag[Languages]]">
Title=<<currentTiddler>><br>{{!!text}}<br>
</$list>
<hr>
<$list filter="[tag[Languages]]">
Title=<<currentTiddler>><br><$text text={{{ [all[current]get[text]] }}}/>
<br>
</$list>
But because I feel for what you are asking, I have being working on a macro
that would look like this
<<nested-filters "[tag[Languages]]" "[<f1>get[text]]" """Title: <<f1>>
vlue: <<f2>>""">>
:Or
<<nested-filters "[tag[Languages]]" "[<f1>get[text]]" """
Title: <<f1>> vlue: <<f2>>
""">>
:Or with a macrocall
Where the last item is what to display, or could be a listtemplate
This would generate behind the scenes as many nested lists as filters
provided.
- But other tricks are available depending on the content of the field
you would like to extract.
*For One way to improve filters and perhaps resolve this gap would be
to consider*
<$list filter="[!is[system]has[caption]]
+[addprefix{!!caption}addprefix[:]]">
</$list>
The above (if it worked) would output a compound value delimited by ":"
Lets say we could use the & or pipe | instead of the +
Where the second run operates on each title as the currenttiddler
filter="[!is[system]has[caption]]
&[get[title]addprefix{!!caption}addprefix[:]]"
Resulting in
caption1:tiddlername1
caption2:tiddlername2
Or
\define break() :<br>
filter="[tag[Languages]] &[addsuffix[<break>]get[text]]"
Resulting in
tiddlername1:
tiddler text1
tiddlername2
tidler text2
Again, where the second run is applied to each title as if it were the
currentTiddler.
....
ie {!!caption} refers to the caption of each of the resulting tiddlers.
Splitting such delimited titles is trivial.
Food for thought?
Regards
Tony
