Synopsis:               Declarative, compositional Wai responses
Category:               Web
Description:
  A method to writing Wai responses
  .
  This library attempts to make it easier to write nice Wai response handlers
  by giving us a Sinatra/
  <https://hackage.haskell.org/package/scotty Scotty>-like syntax for declaring HTTP-verb oriented
  routes, in addition to file-extension handling and rose-tree like composition.
  Not only do we have literal route specification, like
  <https://hackage.haskell.org/package/scotty Scotty> &
  <https://hackage.haskell.org/package/spock Spock>, but we
  can also embed
  <https://hackage.haskell.org/package/attoparsec Attoparsec>
  parsers and <https://hackage.haskell.org/package/regex-compat Regular Expressions>
  /directly/ in our routes, with our handlers
  reflecting their results. As an example:
  .
  > router :: Application
  > router = route handlers
  >   where
  >     handlers = do
  >       handle o
  >         (Just $ get $ text "home")
  >         Nothing
  >       handle ("foo" </> "bar")
  >         (Just $ get $ text "foobar") $ Just $
  >         handle (p ("baz", double) </> o)
  >           (Just $ \d -> get $ text $ LT.pack (show d) <> " bazs")
  >           Nothing
  >       handle (p ("num",double) </> o)
  >         (Just $ \d -> get $ text $ LT.pack $ show d) $ Just $ do
  >         handle "bar"
  >            (Just $ \d -> get $ do
  >                     text $ (LT.pack $ show d) <> " bars")
  >                     json $ (LT.pack $ show d) <> " bars!")
  >            Nothing
  >         handle (r ("email", mkRegex "(^[-a-zA-Z0-9_.]+@[-a-zA-Z0-9]+\\.[-a-zA-Z0-9.]+$)") </> o)
  >            (Just $ \d e -> get $ textOnly $ (LT.pack $ show d) <> " " <> (LT.pack $ show e)
  .
  The route specification syntax is a little strange right now - @l@ specifies
  a "literal chunk" of a handlable url (ie - @l \"foo\" \<\/\> l \"bar\" \<\/\> o@ would
  represent the url @\/foo\/bar@), while @p@ represents a "parsable" url chunk,
  which expects a pair - the left element being merely a reference name for the
  parser during internal plumbing, and the right being the actual @Parser@. @o@ represents
  the end of a url string, and can be used alone in a handler to capture requests
  to the root path.
  .
  Each route being handled needs some kind of content. For every parsed url chunk,
  the route expects a function
  of arity matching 1-for-1 with the parsed contents. For example, @\d -> ...@ in the
  demonstration above is such a function, where @d :: Double@.
  .
  Internally, we match against both the file extension and Accept headers in the
  HTTP request - the Accept header may override the file extension.
  .
  When we test our application:
  .
  >  λ> curl localhost:3000/ -H "Accept: text/plain, */*"
  >  ↪ "home"
  .
  requests may end with index
  .
  >  λ> curl localhost:3000/index -H "Accept: text/plain, */*"
  >  ↪ "home"
  .
  and specify the file extension
  .
  >  λ> curl localhost:3000/index.txt -H "Accept: text/plain, */*"
  >  ↪ "home"
  .
  each responding with the "closest" available file type
  .
  >  λ> curl localhost:3000/index.html -H "Accept: text/html, */*"
  >  ↪ "home"
  .
  >  λ> curl localhost:3000/foo/bar -H "Accept: text/plain, */*"
  >  ↪ "foobar"
  .
  >  λ> curl localhost:3000/foo/bar.txt -H "Accept: text/plain, */*"
  >  ↪ "foobar"
  .
  >  λ> curl localhost:3000/foo/bar/5678.5678 -H "Accept: text/plain, */*"
  >  ↪ "5678.5678 bazs"
  .
  >  λ> curl localhost:3000/1234.1234 -H "Accept: text/plain, */*"
  >  ↪ "1234.1234"
  .
  >  λ> curl localhost:3000/2e5 -H "Accept: text/plain, */*"
  >  ↪ "200000.0"
  .
  >  λ> curl localhost:3000/1234.1234/bar -H "Accept: text/plain, */*"
  >  ↪ "1234.1234 bars"
