-  -- * Working with Extensions
-  -- | Extension states for ALL the extensions installed are stored in the same
-  -- map keyed by their 'Data.Typeable.TypeRep' so if more than one extension
-  -- uses the same type then they'll conflict. This is easily solved by simply
-  -- using a newtype around any types which other extensions may use (your own
-  -- custom types don't need to be wrapped). For example if your extension stores
-  -- a counter as an Int, wrap it in your own custom Counter newtype when storing
-  -- it.
-  --
-  -- Because Extension states are stored by their 'Data.Typeable.TypeRep', they must define an
-  -- instance of 'Data.Typeable.Typeable', luckily GHC can derive this for you with
-  -- @deriving Typeable@.
-  --
-  -- It is also required for all extension states to define an instance of
-  -- 'Data.Default.Default', this is because accessing an extension which has not
-  -- yet been stored will result in the default value.
-  --
-  -- If there's no default value that makes sense for your type, you can define
-  -- a default of 'Data.Maybe.Nothing' and pattern match on its value when you
-  -- access it.
-  --
-  -- Extensions may store state persistently for later access or for other
-  -- extensions to access. Because Rasa can't possibly know the types of the
-  -- state that extensions will store it uses a clever workaround wherein
-  -- extension states are stored in a map of 'Data.Typeable.TypeRep' -> 'Rasa.Internal.Extensions.Ext'
-  -- which is coerced into the proper type when it's extracted. The interface to
-  -- extract or alter a given extension is to use the 'ext' and 'bufExt' lenses.
-  -- Simply use them as though they were lenses to an object of your type and
-  -- it'll all work out.
-  --
-  -- Since it's polymorphic, if ghc can't figure out the type the result is
-  -- supposed to be then you'll need to help it out with a type annotation.
-  -- In practice you won't typically need to do this unless you're

--- | dispatchActionAsync allows you to perform a task asynchronously and then apply the

--- an Action, note that the context in which the second action is executed is
--- NOT the same context in which dispatchActionAsync is called; it is likely that text and
--- other state have changed while the IO executed, so it's a good idea to check
--- (inside the applying Action) that things are in a good state before making
--- changes. Here's an example:
---
--- > asyncCapitalize :: Action ()
--- > asyncCapitalize = do
--- >   txt <- focusDo getText
--- >   -- We give dispatchActionAsync an IO which resolves in an action
--- >   dispatchActionAsync $ ioPart txt

--- >   result <- longAsyncronousCapitalizationProgram txt

--- >   return $ maybeApplyResult txt result
--- >
--- > maybeApplyResult :: Text -> Text -> Action ()
--- > maybeApplyResult oldTxt capitalized = do
--- >   -- We get the current buffer's text, which may have changed since we started
--- >   newTxt <- focusDo getText
--- >   if newTxt == oldTxt
--- >     -- If the text is the same as it was, we can apply the transformation
--- >     then focusDo (setText capitalized)

--- | Don't let the type signature confuse you; it's much simpler than it seems.
--- The first argument is a function which takes an action provider; the action provider
--- will be passed a dispatch function which can be called as often as you like with @Action ()@s.
--- When it is passed an 'Action' it forks off an IO to dispatch that 'Action' to the main event loop.

--- | This allows long-running IO processes to provide Events to Rasa asyncronously.
---
--- Don't let the type signature confuse you; it's much simpler than it seems.
---
--- Let's break it down:
---
--- Using the 'Dispatcher' type with asyncEventProvider requires the @RankNTypes@ language pragma.
---
--- This type as a whole represents a function which accepts a 'Dispatcher' and returns an 'IO';
--- the dispatcher itself accepts data of ANY 'Typeable' type and emits it as an event (see "Rasa.Internal.Events").
---
--- When you call 'asyncEventProvider' you pass it a function which accepts a @dispatch@ function as an argument
--- and then calls it with various events within the resulting 'IO'.
---
--- Note that asyncEventProvider calls forkIO internally, so there's no need to do that yourself.
---
--- Here's an example which fires a @Timer@ event every second.
---
--- > {-# language RankNTypes #-}
--- > data Timer = Timer
--- > myTimer :: Dispatcher -> IO ()
--- > myTimer dispatch = forever $ dispatch Timer >> threadDelay 1000000
--- >
--- > myAction :: Action ()
