For instance, on this http://www.yesodweb.com/blog/2012/04/yesod-js-todo they have a few constructs like this:
mkYesod "App" [parseRoutes| / HomeR GET /todo TodosR GET PUT /todo/#TodoId TodoR GET DELETE |]
It seems that the inline text is going to be fed to parseRoutes. How does that constructs work (links?)? I already know list comprehensions which appear to be related with this.
That's a Template Haskell (TH) quasi-quotation. The 'parseRoutes' function is the quasi-quoter. Check [1] and [2] for starters =). Also, don't be afraid to ask questions on the Yesod mailing list (of which I'm a subscriber, too).
