Unique-keyed mappings

data UniqFM key ele Source #

A finite map from uniques of one type to elements in another type.

The key is just here to keep us honest. It's always safe to use a single type as key. If two types don't overlap in their uniques it's also safe to index the same map at multiple key types. But this is very much discouraged.

plusUFM_CD :: (elta -> eltb -> eltc) -> UniqFM key elta -> elta -> UniqFM key eltb -> eltb -> UniqFM key eltc Source #

`plusUFM_CD f m1 d1 m2 d2` merges the maps using f as the combinding function and d1 resp. d2 as the default value if there is no entry in m1 reps. m2. The domain is the union of the domains of m1 and m2.

IMPORTANT NOTE: This function strictly applies the modification function and forces the result unlike most the other functions in this module.

Representative example:

plusUFM_CD f {A: 1, B: 2} 23 {B: 3, C: 4} 42
   == {A: f 1 42, B: f 2 3, C: f 23 4 }

plusUFM_CD2 :: (Maybe elta -> Maybe eltb -> eltc) -> UniqFM key elta -> UniqFM key eltb -> UniqFM key eltc Source #

`plusUFM_CD2 f m1 m2` merges the maps using f as the combining function. Unlike plusUFM_CD, a missing value is not defaulted: it is instead passed as Nothing to f. f can never have both its arguments be Nothing.

IMPORTANT NOTE: This function strictly applies the modification function and forces the result.

`plusUFM_CD2 f m1 m2` is the same as `plusUFM_CD f (mapUFM Just m1) Nothing (mapUFM Just m2) Nothing`.

pprUFM Source #

Arguments

:: UniqFM key a	The things to be pretty printed
-> ([a] -> SDoc)	The pretty printing function to use on the elements
-> SDoc	`SDoc` where the things have been pretty printed

Pretty-print a non-deterministic set. The order of variables is non-deterministic and for pretty-printing that shouldn't be a problem. Having this function helps contain the non-determinism created with nonDetEltsUFM.

pprUFMWithKeys Source #

Arguments

:: UniqFM key a	The things to be pretty printed
-> ([(Unique, a)] -> SDoc)	The pretty printing function to use on the elements
-> SDoc	`SDoc` where the things have been pretty printed

Pretty-print a non-deterministic set. The order of variables is non-deterministic and for pretty-printing that shouldn't be a problem. Having this function helps contain the non-determinism created with nonDetUFMToList.

pluralUFM :: UniqFM key a -> SDoc Source #

Determines the pluralisation suffix appropriate for the length of a set in the same way that plural from Outputable does for lists.
