Definitions by pattern matching

14 declarations

valuecheckFunDef :: DefInfo -> QName -> [Clause] -> TCM ()

valuecheckMacroType :: Type -> TCM ()

valueisAlias :: [Clause] -> Type -> Maybe (Expr, Maybe Expr, MetaId)

A single clause without arguments and without type signature is an alias.

valuecheckAlias

:: Type
-> ArgInfo
-> DefInfo
-> QName
-> Expr
-> Maybe Expr
-> TCM ()

Check a trivial definition of the form f = e

valuecheckFunDef'

:: Type
the type we expect the function to have
-> ArgInfo
is it irrelevant (for instance)
-> Maybe ExtLamInfo
does the definition come from an extended lambda (if so, we need to know some stuff about lambda-lifted args)
-> Maybe QName
is it a with function (if so, what's the name of the parent function)
-> DefInfo
range info
-> QName
the name of the function
-> [Clause]
the clauses to check
-> TCM ()

Type check a definition by pattern matching.

valuecheckFunDefS

:: Type
the type we expect the function to have
-> ArgInfo
is it irrelevant (for instance)
-> Maybe ExtLamInfo
does the definition come from an extended lambda (if so, we need to know some stuff about lambda-lifted args)
-> Maybe QName
is it a with function (if so, what's the name of the parent function)
-> DefInfo
range info
-> QName
the name of the function
-> Maybe (Substitution, Map Name LetBinding)
substitution (from with abstraction) that needs to be applied to module parameters, and let-bindings inherited from parent clause
-> [Clause]
the clauses to check
-> TCM ()

Type check a definition by pattern matching.

valueuseTerPragma :: Definition -> TCM Definition

Set funTerminates according to termination info in TCEnv, which comes from a possible termination pragma.

valuemapLHSCores :: (LHSCore -> LHSCore) -> RHS -> RHS

Modify all the LHSCore of the given RHS. (Used to insert patterns for rewrite or the inspect idiom)

valueinsertNames :: [Arg (Maybe BindName)] -> RHS -> RHS

Insert some names into the with-clauses LHS of the given RHS. (Used for the inspect idiom)

valueinsertInspects :: [Arg (Maybe BindName)] -> LHSCore -> LHSCore

valueinsertPatterns :: [Arg Pattern] -> RHS -> RHS

Insert some with-patterns into the with-clauses LHS of the given RHS. (Used for rewrite)

valueinsertPatternsLHSCore :: [Arg Pattern] -> LHSCore -> LHSCore

Insert with-patterns before the trailing with patterns. If there are none, append the with-patterns.

datadata WithFunctionProblem

Parameters for creating a with-function.
