Hi I ran across a similar problem when developing my gTiD system: http://wills.tiddlyspot.com/
My solution was to use fields rather than tags, since tiddlers can be filtered according to a match with the value of a field. This technique doesn't quite answer your question, but provides a work around. Take for example your outline type scenario and using a field named 'type' -- the 'type' field can take values such as:'title', 'chapter', 'section', 'sub-section', 'paragraph' ... and so on. Tiddlers may be filtered with expressions such as: '[field:type[section]]', '[field:type[sub-section]]' ... and so on. As these filter expressions select only those tiddlers where the value is a match, there is no necessity to filter out other values. Fields and tags can be used together in filter expressions -- thus a hybrid outline scheme can make use of fields for the main hierarchy and tags for the details. regards On Saturday, June 28, 2014 12:48:59 AM UTC+2, Jon wrote: > > Hi, > > If I have some tiddlers tagged with A, some with A & B and some with A, B > & C, how do I filter the tiddlers which are only tagged with A? > > Thanks, Jon > -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
