So here is my use case and I'd like to propose a feature (obviously I would implement and send a pull request).
I have a static site blog (
http://tritarget.org/) And to be honest the build is way to complicated for my liking. Jekyl kept fighting me and using metelsmith now is like a 10 minute deploy step. It's silly. None of which takes in to account JavaScript. I'm a JS developer by day. I love frameworks like Ember.JS and such. But these frameworks are not so useful as a blog because search engines can't crawl it well. Then I saw hoe
tiddlywiki.com does it! Perfect a fully fledged (and I'll admit, beautiful) single page app that does everything I want including writing out tiddlers to static files. Perfect!
The gotcha: the current site already has several back links to it. Changing the names and file structure of those static HTML files would trash the current search results and break a lot of other people's links. So what I want to to recreate the site in TiddlyWiki and have my build process also render the static files but use a field to determine the outputs file/directory names. This way new content can easily be managed and created while old content can keep it's legacy paths.
I'd propose to add a feature to look at a tiddlers fields for something like "_static_path" and use that (kinda like how external images use "_cononical_url").
I'd like to work on this and would be happy to send a PR. Is it worth it for the community?
