Bug fixes
Prevent double-escaping in link segments

0.12
Significant changes
servant-client servant-client-core
Factored out of servant-client all the functionality that was
independent of the http-client backend.
(#803
#821 )
If you have own combinators, you’ll need to add an additional m argument
in HasClient, Client and clientWithRoute:
-class HasClient api
- type Client (api :: *) :: *
- clientWithRoute :: Proxy api -> Req -> Client api
+class HasClient m api
+ type Client (m :: * -> *) (api :: *) :: *
+ clientWithRoute :: Proxy m -> Proxy api -> Request -> Client m api
See https://github.com/haskell-servant/servant-auth/pull/67/commits/f777818e3cc0fa3ed2346baff8328e96d62b1790 for a real world example.
servant-server Added hoistServer member to the HasServer class, which is HasServer
specific enter.
(#804
#824 )
enter isn’t exported from Servant module anymore. You can change
enter to hoistServer in a straight forward way.
Unwrap natural transformation and add a api type Proxy:
-server = enter (NT nt) impl
+server = hoistServer (Proxy :: Proxy MyApi) nt impl
If you have own combinators, you’ll need to define a new method of
HasServer class, for example:
type ServerT (MyCombinator :> api) m = MyValue -> ServerT api m
hoistServerWithContext _ pc nt s = hoistServerWithContext (Proxy :: Proxy api) pc nt . s
See https://github.com/haskell-servant/servant-auth/pull/67/commits/8ee3b6315247ac076516213fd7cfcdbfdb583ac9 for a real world example.
Add Description and Summary combinators
(#767 )
It’s possible to annotate endpoints with free form text.
This information is used by e.g. by servant-swagger, see screenshot in
https://github.com/phadej/servant-swagger-ui
Lower :> and :<|> infix precedence to 4 and 3 respectively
(#761 )
This shouldn’t affect you, except if you define your own infix operators
for Servant type-level DSL.
