Here's some haskell code:

```haskell
titleRoute :: Metadata -> Maybe Routes
titleRoute metadata = constRoute <$> fileNameFromTitle metadata
    where
      slug :: String -> String
      slug = T.unpack . (`T.append` ".html") . Slugger.toSlug . T.pack

      ignore :: Eq a => a -> a -> Maybe a
      ignore shouldBeIgnored value
        | shouldBeIgnored == value = Nothing
        | otherwise = Just value

      fileNameFromTitle :: Metadata -> Maybe FilePath
      fileNameFromTitle metadata = slug <$> (ignore "" =<< lookupString "title" metadata)
```

Here's a graphviz graph

```dot
digraph G {

  subgraph cluster_0 {
    style=filled;
    color=lightgrey;
    node [style=filled,color=white];
    a0 -> a1 -> a2 -> a3;
    label = "process #1";
  }

  subgraph cluster_1 {
    node [style=filled];
    b0 -> b1 -> b2 -> b3;
    label = "process #2";
    color=blue
  }
  start -> a0;
  start -> b0;
  a1 -> b3;
  b2 -> a3;
  a3 -> a0;
  a3 -> end;
  b3 -> end;

  start [shape=Mdiamond];
  end [shape=Msquare];
}
```
