1−synopsis: Display capture hints in router layout

2−prs: #1556

3−

4−description: {

5−

6−This PR enhances the `Servant.Server.layout` function, which produces a textual description of the routing layout of an API. More precisely, it changes `<capture>` blocks, so that they display the name and type of the variable being captured instead.

7−

8−Example:

9−

10−For the following API

11−```haskell

12−type API =

13− "a" :> "d" :> Get '[JSON] NoContent

14− :<|> "b" :> Capture "x" Int :> Get '[JSON] Bool

15− :<|> "a" :> "e" :> Get '[JSON] Int

16−```

17−

18−we previously got the following output:

19−

20−```

21−/

22−├─ a/

23−│ ├─ d/

27−└─ b/

28− └─ <capture>/

29− ├─•

30− ┆

31− └─•

48−```

49−

50−This change is achieved by the introduction of a CaptureHint type, which is passed as an extra argument to the CaptureRouter and CaptureAllRouter constructors for the Router' type.

51−CaptureHint values are then used in routerLayout, to display the name and type of captured values, instead of just `<capture>` previously.

52−

53−N.B.:

54−Because the choice smart constructor for routers can aggregate Capture combinators with different capture hints, the Capture*Router constructors actually take a list of CaptureHint, instead of a single one.

55−

56−This PR also introduces Spec tests for the routerLayout function.

57−

58−Warning:

59−This change is potentially breaking, because it adds the constraint `Typeable a` to all types that are to be captured. Because all types are typeable since GHC 7.10, this is not as bad as it sounds ; it only break expressions where `a` is quantified in an expression with `Capture a`.

60−In those cases, the fix is easy: it suffices to add `Typeable a` to the left-hand side of the quantification constraint.

61−

62−For instance, the following code will no longer compile:

63−```haskell

64−type MyAPI a = Capture "foo" a :> Get '[JSON] ()

65−

66−myServer :: forall a. Server (MyAPI a)

67−myServer = const $ return ()

68−

69−myApi :: forall a. Proxy (MyAPI a)

70−myApi = Proxy

71−

72−app :: forall a. (FromHttpApiData a) => Application

73−app = serve (myApi @a) (myServer @a)

74−```

75−

76−Indeed, `app` should be replaced with:

77−```haskell

78−app :: forall a. (FromHttpApiData a, Typeable a) => Application

79−app = serve (myApi @a) (myServer @a)

80−```
