[twdev] file "save as" interface?

Fri, 17 Dec 2010 08:36:10 -0800

I'm using tiddlywiki's file management code and I'm trying to find a way to effectively support a "Save As" file dialog. "Save" works fine, as tw already knows the file path. In fact, tw can save to any specified file path. The problem is that there is no implementation of an interface for specifying that file path. If I want to implement "load" I can do so by leveraging the built-in browser interface for specifying a file to upload---I just introduce a form with a "choose file" button, the browser takes care of the interaction, and I pull the file path out of the form. But I know of no analogous way to get access to the information produced by the browser's "save as" dialog---it only seems to be possible to trigger that dialog via a server download, and there's no way I can see to capture the necessary file path information on the client. If anyone has a way around this, I'd love to know. If not, I'd love to see it addressed in future tw development.
