[Need advice] Capture fragment from URI

[rizary]

Hi, when I have link to some blog post /#News/August/01/08/2019/big-announcement-to-tell, what is the best possible way to get each of fragment like "August" or "2019".

Or can we just redirect to /#News and parse August/01/08/2019/big-announcement-to-tell by our self?

There are several ways, depending on what you want to do. If you want to get each fragment and build your page top-down, you can use the standard withRoute function and match on each component:

withRoute $ \case ->
  Just "News" -> withRoute $ \day ->
    withRoute $ \month ->
      withRoute $ \year ->
        withRoute $ \name ->
          --build page with all these pieces

If you want them all at once you can just use allRouteSegments which is a Dynamic t [Text] (in this case) and you can build DOM with normal reflex combinators over this dynamic. For example:

fullPath <- allRouteSegments
month <- holdUniqDyn $ fullPath <&> (!! 3) -- Beware: (!!) is partial
