addImplementation

Arguments

:: Bool

whether the name is an Integer implementation

-> Bool

whether to include the implementation in implementation search

-> Name

the name of the interface

-> Name

the name of the implementation

-> Idris ()

Add an interface implementation function.

Precondition: the implementation should have the correct type.

Dodgy hack 1: Put integer implementations first in the list so they are resolved by default.

Dodgy hack 2: put constraint chasers (ParentN) last

addOpenImpl :: [Name] -> Idris [Name]

Add a privileged implementation - one which implementation search will happily resolve immediately if it is type correct This is used for naming parent implementations when defining an implementation with constraints. Returns the old list, so we can revert easily at the end of a block

getInternalApp :: FilePath -> Int -> Idris PTerm

clearOrigPats :: Idris ()

Pattern definitions are only used for coverage checking, so erase them when we're done

clearPTypes :: Idris ()

Erase types from Ps in the context (basically ending up with what's in the .ibc, which is all we need after all the analysis is done)

getPriority :: IState -> PTerm -> Int

Calculate a priority for a type, for deciding elaboration order * if it's just a type variable or concrete type, do it early (0) * if there's only type variables and injective constructors, do it next (1) * if there's a function type, next (2) * finally, everything else (3)
