Were you tempted to -- reach for @'fromJust'@ or @'error'@ to handle the "impossible" case, when you knew that -- @'lookup'@ should give @'Just' v@? (and did shifting requirements ever make the impossible -- become possible after all?) -- -- "Data.Map.Justified" provides a zero-cost @newtype@ wrapper around "Data.Map"'s @'Data.Map.Map'@ that enables you -- to separate the /proof that a key is present/ from the /operations using the key/. Once -- you prove that a key is present, you can use it @Maybe@-free in any number of other -- operations -- sometimes even operations on other maps! -- -- None of the functions in this module can cause a run-time error, and very few -- of the operations return a @'Maybe'@ value. -- -- See the "Data.Map.Justified.Tutorial" module for usage examples. -- -- === Example -- @ -- withMap test_table $ \\table -> do -- -- case member 1 table of -- -- Nothing -> putStrLn "Sorry, I couldn\'t prove that the key is present." -- -- Just key -> do -- -- -- We have proven that the key is present, and can now use it Maybe-free... -- putStrLn ("Found key: " ++ show key) -- putStrLn ("Value for key: " ++ lookup key table) -- -- -- ...even in certain other maps! -- let table\' = reinsert key "howdy" table -- putStrLn ("Value for key in updated map: " ++ lookup key table\') -- @ -- Output: -- -- @ -- Found key: Key 1 -- Value for key: hello -- Value for key in updated map: howdy -- @ -- -- == Motivation: "Data.Map" and @'Maybe'@ values -- -- Suppose you have a key-value mapping using "Data.Map"'s type @'Data.Map.Map' k v@. Anybody making -- use of @'Data.Map.Map' k v@ to look up or modify a value must take into account the possibility -- that the given key is not present. -- -- In "Data.Map", there are two strategies for dealing with absent keys: -- -- 1. Cause a runtime error (e.g. "Data.Map"'s @'Data.Map.!'@ when the key is absent) -- -- 2. Return a @'Maybe'@ value (e.g. "Data.Map"'s @'Data.Map.lookup'@) -- -- The first option introduces partial functions, so is not very palatable. But what is -- wrong with the second option? -- -- To understand the problem with returning a @'Maybe'@ value, let's ask what returning -- @Maybe v@ from @'Data.Map.lookup' :: k -> Map k v -> Maybe v@ really does for us. By returning -- a @Maybe v@ value, @lookup key table@ is saying "Your program must account -- for the possibility that @key@ cannot be found in @table@. I will ensure that you -- account for this possibility by forcing you to handle the @'Nothing'@ case." -- In effect, "Data.Map" is requiring the user to prove they have handled the -- possibility that a key is absent whenever they use the @'Data.Map.lookup'@ function. -- -- == Laziness (the bad kind) -- -- Every programmer has probably had the experience of knowing, somehow, that a certain -- key is going to be present in a map. In this case, the @'Maybe' v@ feels like a burden: -- I already /know/ that this key is in the map, why should I have to handle the @'Nothing'@ case? -- -- In this situation, it is tempting to reach for the partial function @'Data.Maybe.fromJust'@, -- or a pattern match like @'Nothing' -> 'error' "The impossible happened!"@. But as parts of -- the program are changed over time, you may find the impossible has become possible after -- all (or perhaps you'll see the dreaded and unhelpful @*** Exception: Maybe.fromJust: Nothing@) -- -- It is tempting to reach for partial functions or "impossible" runtime errors here, because -- the programmer has proven that the key is a member of the map in some other way. They -- know that @'Data.Map.lookup'@ should return a @'Just' v@ --- but the /compiler/ doesn't know this! -- -- The idea behind "Data.Map.Justified" is to encode the programmer's knowledge that a key -- is present /within the type system/, where it can be checked at compile-time. Once a key -- is known to be present, @'Data.Map.Justified.lookup'@ will never fail. Your justification -- removes the @'Just'@! -- -- == How it works -- -- Evidence that a key can indeed be found in a map is carried by a phantom type parameter @ph@ -- shared by both the @'Data.Map.Justified.Map'@ and @'Data.Map.Justified.Key'@ types. If you are -- able to get your hands on a value of type @'Key' ph k@, then you must have already proven that -- the key is present in /any/ value of type @'Map' ph k v@. -- -- The @'Key' ph k@ type is simply a @newtype@ wrapper around @k@, but the phantom type @ph@ allows -- @'Key' ph k@ to represent both /a key of type @k@/ __and__ /a proof that the key is present in/ -- /all maps of type @'Map' ph k v@/. -- -- There are several ways to prove that a key belongs to a map, but the simplest is to just use -- "Data.Map.Justified"'s @'Data.Map.Justified.member'@ function. In "Data.Map", @'Data.Map.member'@ -- has the type -- -- @'Data.Map.member' :: 'Ord' k => k -> 'Data.Map.Map' k v -> 'Bool'@ -- -- and reports whether or not the key can be found in the map. In "Data.Map.Justified", -- @'Data.Map.Member'@ has the type -- -- @'member' :: 'Ord' k => k -> 'Map' ph k v -> 'Maybe' ('Key' ph k)@ -- -- Instead of a boolean, @'Data.Map.Justified.member'@ either says "the key is not present" -- (@'Nothing'@), or gives back the same key, /augmented with evidence that they key/ -- /is present/. This key-plus-evidence can then be used to do any number of @'Maybe'@-free -- operations on the map. -- -- "Data.Map.Justified" uses the same rank-2 polymorphism trick used in the @'Control.Monad.ST'@ monad to -- ensure that the @ph@ phantom type can not be extracted; in effect, the proof that a key is -- present can't leak to contexts where the proof would no longer be valid. -- module Data.Map.Justified ( -- * Map and Key types Map , Key , Index , theMap , theKey , theIndex -- * Evaluation , withMap , withSingleton , KeyInfo(..) , MissingReference , withRecMap -- * Gathering evidence , member , keys , lookupMay , lookupLT , lookupLE , lookupGT , lookupGE -- * Safe lookup , lookup , (!) -- * Preserving key sets -- ** Localized updates , adjust , adjustWithKey , reinsert -- ** Mapping values , mapWithKey , traverseWithKey , mapAccum , mapAccumWithKey -- ** Zipping , zip , zipWith , zipWithKey -- * Enlarging key sets -- ** Inserting new keys , inserting , insertingWith -- ** Unions , unioning , unioningWith , unioningWithKey -- * Reducing key sets -- ** Removing keys , deleting , subtracting -- ** Filtering , filtering , filteringWithKey -- ** Intersections , intersecting , intersectingWith , intersectingWithKey -- * Mapping key sets , mappingKeys , mappingKnownKeys , mappingKeysWith , mappingKnownKeysWith -- * Indexing , findIndex , elemAt -- * Utilities , tie ) where import Control.Arrow ((&&&)) import Data.List (partition) import qualified Data.Map as M import Prelude hiding (lookup, zip, zipWith) import Data.Roles import Data.Type.Coercion {-------------------------------------------------------------------- Map and Key types --------------------------------------------------------------------} -- | A "Data.Map" @'Data.Map.Map'@ wrapper that allows direct lookup of keys that -- are known to exist in the map. -- -- Here, "direct lookup" means that once a key has been proven -- to exist in the map, it can be used to extract a value directly -- from the map, rather than requiring a @'Maybe'@ layer. -- -- @'Map'@ allows you to shift the burden of proof that a key exists -- in a map from "prove at every lookup" to "prove once per key". newtype Map ph k v = Map (M.Map k v) deriving (Eq, Ord, Show, Functor, Foldable, Traversable) type role Map nominal nominal representational -- | A key that knows it can be found in certain @'Map'@s. -- -- The evidence that the key can be found in a map is carried by -- the type system via the phantom type parameter @ph@.
