Documentation
A global typecheckable-thing, essentially anything that has a name.
Not to be confused with a TcTyThing, which is also a typecheckable
thing but in the *local* context. See GHC.Tc.Utils.Env for how to retrieve
a TyThing given a Name.
Instances
A typecheckable thing available in a local context. Could be
AGlobal TyThing, but also lexically scoped variables, etc.
See GHC.Tc.Utils.Env for how to retrieve a TyThing given a Name.

tcExtendLetEnv :: TopLevelFlag -> TcSigFun -> IsGroupClosed -> [TcId] -> TcM a -> TcM a Source #
tcExtendSigIds :: TopLevelFlag -> [TcId] -> TcM a -> TcM a Source #
isTypeClosedLetBndr :: Id -> Bool Source #
tcCheckUsage :: Name -> Mult -> TcM a -> TcM (a, HsWrapper) Source #
tcCheckUsage name mult thing_inside runs thing_inside, checks that the
usage of name is a submultiplicity of mult, and removes name from the
usage environment. See also Note [Wrapper returned from tcSubMult] in
GHC.Tc.Utils.Unify, which applies to the wrapper returned from this function.
tcLookupTcTyCon :: HasDebugCallStack => Name -> TcM TcTyCon Source #
pprBinders :: [Name] -> SDoc Source #
tcAddPatSynPlaceholders :: [PatSynBind GhcRn GhcRn] -> TcM a -> TcM a Source #
tcInitOpenTidyEnv :: [TyCoVar] -> TcM TidyEnv Source #
Get a TidyEnv that includes mappings for all vars free in the given
type. Useful when tidying open types.
isBrackStage :: ThStage -> Bool Source #
newDFunName :: Class -> [Type] -> SrcSpan -> TcM Name Source #
Make a name for the dict fun for an instance decl. It's an *external* name, like other top-level names, and hence must be made with newGlobalBinder.
mkWrapperName :: (MonadIO m, HasModule m) => IORef (ModuleEnv Int) -> String -> String -> m FastString Source #
mkWrapperName ref what nameBase
See Note [Generating fresh names for FFI wrappers] for ref's purpose.
