Description
Type checker for defined syntax constructors define f xs = e.
Synopsis

- checkDefinitions :: CF -> Err CF
- checkDefinition' :: ListConstructors -> Context -> RFun -> [String] -> Exp -> Err (Telescope, (Exp, Base))
- buildSignature :: [Rule] -> Err Signature
- buildContext :: CF -> Context
- ctxTokens :: Context -> [String]
- isToken :: String -> Context -> Bool
- data ListConstructors = LC {}
Type checker entry point
runTypeChecker :: Err a -> Either String a Source #
checkDefinitions :: CF -> Err CF Source #
Entry point.
Backdoor for rechecking defined syntax constructors for list types
buildSignature :: [Rule] -> Err Signature Source #
Create context containing the types of all labels, computed from the rules.
Fail if a label is used at different types.
buildContext :: CF -> Context Source #
