Hi Tony, after some testing I may have a first idea, but there are two things:
- Calls: Javascript macros are called when the tiddler is parsed. So you would need something that rerenders the tiddler - for instance the list widget you mentioned upon changes in the filter result - to call the macro multiple times without closing and reopening the tiddler. As an example if you change your variable in one tiddler and in another already open tiddler get the variable's value it won't be updated until the tiddler is reloaded. I currently don't have an idea for that. - Permanent Save: Due to javascript macros not being able to directly write to a field by themselves currently the variables only last as long as the wiki is not closed or reloaded. For this I might have a solution, but will need to play around a little more with it, before being able to say if it actually works or not.
