-- | Selectors for reading and updating data.
--
-- References are data accessors that can read, write or update the
-- accessed infromation through their context. They are first-class
-- values, can be passed in functions, transformed, combined. References
-- generalize lenses, folds and traversals for haskell (see:
-- https://hackage.haskell.org/package/lens).
--
-- References are more general than field selectors in traditional
-- languages.
--
--
-- - References are first-class values. If there is a struct in C, for
-- example, with an int field fl, then fl can only be used
-- as part of an expression. One can not generalize a function to take a
-- field selector and transform the selected data or use it in other
-- ways.
-- - They can have different meanings, while field accessors can only
-- represent data-level containment. They can express uncertain
-- containment (like field selectors of C unions), different viewpoints
-- of the same data, and other concepts.
--
--
-- There are two things that references can do but the previously
-- mentioned access methods don't.
--
--
-- - References can cooperate with monads, for example IO. This opens
-- many new applications.
-- - References can be added using the &+& operator,
-- to create new lenses more easily.
--
--
-- Basic idea taken from the currently not maintained package
-- https://hackage.haskell.org/package/yall.
--
-- An example use of the references (a logger application that spawns new
-- threads to update a global log):
--
--
-- logger =
-- (forever $ do
-- log <- logChan ^? chan&logRecord -- Extract the log record from the received log message
-- thrId <- forkIO (do time <- getTime
-- ioref&lastLogTime != time $ logDB -- Update the last logging time mutable log database
-- let logMsg = senderThread .- show -- Transform the thread id to a string and
-- $ loggingTime .= time -- update the time
-- $ log -- inside the log message
-- ioref&debugInfos !~ addLogEntry log $ logDB -- update the table of log entries
-- mvar !- (+1) $ count )
-- mvar !- (thrId:) $ updaters -- Record the spawned thread
-- ) `catch` stopUpdaters updaters
-- where stopUpdaters updaters ThreadKilled =
-- mvar&traverse !| killThread $ updaters -- Kill all spawned threads before stopping
--
--
-- There are a bunch of predefined references for datatypes included in
-- standard libraries.
--
-- New references can be created in several ways:
--
--
-- - From getter, setter and updater, using the reference
-- function.
-- - From getter and setter, using one of the simplified functions
-- (lens, simplePartial, partial, ...).
-- - Using the Data.Traversal instance on a datatype to generate
-- a traversal of each element.
-- - Using lenses from Control.Lens package. There are a lot of
-- packages defining lenses, folds and traversals for various data
-- structures, so it is very useful that all of them can simply be
-- converted into a reference.
-- - Generating references for newly defined datatypes using the
-- makeReferences Template Haskell function.

@version 0.3.0.1
-- | This module declares the representation and basic classes of
-- references. Supplies primitive functions to create references.
--
-- This module should not be imported directly.
module Control.Reference.Representation
-- | A reference is an accessor to a part or different view of some data.
-- The referenc has a separate getter, setter and updater. In some cases,
-- the semantics are a bit different
--
-- Reference laws
--
-- As the references are generalizations of lenses, they should conform
-- to the lens laws:
--
-- 1) You get back what you put in:
--
--
-- refSet l a s >>= refGet l return ≡ a
--
--
-- 2) Putting back what you got doesn't change anything:
--
--
-- refGet l return a >>= \b -> refSet l b s ≡ s
--
--
-- 3) Setting twice is the same as setting once:
--
--
-- refSet l a s >>= refSet l b ≡ refSet l b s
--
--
-- But because update, set and get are different operations, .
--
-- 4) Updating something is the same as getting and then setting (if the
-- reader and writer monads are the same, or one can be converted into
-- the other):
--
--
-- refGet l a >>= f >>= \b -> refSet l b s ≡ refUpdate l f s
--
--
-- This has some consequences. For example lensUpdate l id =
-- return.
--
--
--
--
-- - w Writer monad, controls how the value can be
-- reassembled when the part is changed. See differences between
-- Lens, IOLens and StateLens
-- - r Reader monad. Controls how part of the value can
-- be asked. See differences between Lens, Partial and
-- Traversal
-- - w' Backward writer monad. See turn
-- - r' Backward reader monad. See turn
-- - s The type of the original context.
-- - t The after replacing the accessed part to
-- something of type b the type of the context changes to
-- t.
-- - a The type of the accessed part.
-- - b The accessed part can be changed to something of
-- this type.
--
--
-- Usually s and b determines t, t
-- and a determines s.
--
-- The reader monad usually have more information (Morph w
-- r).

-- | Generates the normal haskell tuples ((a,b), (a,b,c),
-- (a,b,c,d))
hsTupConf :: TupleConf
-- | Creates Lens_1 ... Lens_n classes, and instances for
-- tuples up to m.
--
-- Classes and instances look like the following:
--
--
-- class Lens_1 s t a b | s -> a, t -> b
-- , a t -> s, b s -> t where
-- _1 :: Lens s t a b
--
-- instance Lens_1 (a,b) (a',b) a a' where
-- _1 = lens ((a,b) -> a) (a' (a,b) -> (a',b))
--
makeTupleRefs :: TupleConf -> Int -> Int -> Q [Dec]
-- | A module where tuple classes and instances are created up to 16-tuple
-- using makeTupleRefs. The number of classes and instances can be
-- changed by hiding import from this module and calling
-- makeTupleRefs in an other module.
