http://www.TiddlyTools.com/#MissingTiddlersPlugin uses regular expressions to match titles of "missing" tiddlers and provide alternative, fallback content. After installing the plugin, you can then simply create a tiddler called [[MissingTiddlers]] containing sections, where the section headings are regexp patterns to match and the section content is the fallback content to use when matched. You can use any content as a fallback, including static text, TW macros, etc. For your purposes ("redirecting" to another tiddler), you could use a <<tiddler>> macro to display the desired 'redirected' content. You can also embed a special marker sequence, "$1" (without quotes) within the fallback content to display the actual name of the tiddler used in the link. For example, suppose [[MissingTiddlers]] contains: !(web|online)( )(pages|sites)( that| )( I )(like|like to(read| browse|explore)) $1 <<tiddler MyFavoriteSites>> and [[MyFavoriteSites]] contains: http://www.TiddlyWiki.com/ http://www.TiddlyTools.com/ Then, when you click on a link like: [[web sites that I like to read]], MissingTiddlersPlugin will find the matching regexp in the MissingTiddlers list, and display: web sites that I like to read: http://www.TiddlyWiki.com/ http://www.TiddlyTools.com/ Note: if you actually want to *redirect* to another tiddler (rather than just showing the fallback content), you can install http://www.TiddlyTools.com/#SlideshowTimer The SlideshowTimer transclusion automatically opens the specified tiddler (e.g., [[MyFavoriteSites]]) after an indicated delay (0=immediate) and, with the optional "close" keyword, automatically closes the current tiddler that was being displayed (i.e. it 'redirects' from one tiddler to another). This would allow to you write something like this in [[MissingTiddlers]]: !(web|online)( )(pages|sites)( that| )( I )(like|like to(read| browse|explore)) <<tiddler SlideshowTimer with: MyFavoriteSites 0 close>> The net result is that any link that matches your desired regexp pattern(s) in [[MissingTiddlers]] would redirect to [[MyFavoriteSites]] instead.
