While it isn't a tiddlywiki based solution it sounds like a perl script would take care of your problems. Something like adding <br> before each \n character may preserve you formatting and it could do this like convert a .txt file into a .tid file with the needed formatting.
Also, look at the format options for the view widget, one should let you view pain text complete with line breaks. -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
