Hi everybody
After tinkering with the source code of StorySaverPlugin, I've found
the answer to my own query (and maybe others'). I post it here for
whomever wants it. It uses inlineJavascriptPlugin and is certainly not
optimized ;-)
What it does: checks for a certain field==value among all tiddlers,
lists all positives in a given Tiddler tid (in my example it is called
'CurrentTiddlers'), closes all tiddlers and then opens the ones listed
in CurrentTiddler.
<<tiddler WriteTiddlersWith##script>>
/%
!script
//
<script label="WriteTiddlersWith">
var tid='CurrentTiddlers';
var fieldname='yourfield'; // put in what you want
var fieldvalue='yourvalue'; // same thing
var tidlist=[];
// gets in tidlist all tiddlers satisfying a given condition
store.forEachTiddler(function(title,tiddler){
// var t=store.getTiddler(title);
var val=store.getValue(title,fieldname);
if (val==undefined) return;
if (val==fieldvalue) tidlist.pushUnique('[['+title+']]');
});
tidlist=tidlist.join('\n');
var t=store.getTiddler(tid); var tags=t?t.tags:[];
store.saveTiddler(tid,tid,tidlist,config.options.txtUserName,new
Date(),tags,t?t.fields:null);
story.closeAllTiddlers();
story.displayTiddlers(null,store.getTiddlerText(tid).readBracketedList());
</script>
!end
