class (MonadConstraint m, MonadReduce m, MonadAddContext m, MonadTCEnv m, ReadTCState m, HasBuiltins m, HasConstInfo m, MonadDebug m) => MonadMetaSolver m where Source #

Monad service class for creating, solving and eta-expanding of metavariables.

Methods

newMeta' :: MetaInstantiation -> Frozen -> MetaInfo -> MetaPriority -> Permutation -> Judgement a -> m MetaId Source #

Generate a new meta variable with some instantiation given. For instance, the instantiation could be a `PostponedTypeCheckingProblem`.

assignV :: CompareDirection -> MetaId -> Args -> Term -> CompareAs -> m () Source #

Assign to an open metavar which may not be frozen. First check that metavar args are in pattern fragment. Then do extended occurs check on given thing.

Assignment is aborted by throwing a `PatternErr` via a call to `patternViolation`. This error is caught by `catchConstraint` during equality checking (`compareAtom`) and leads to restoration of the original constraints.

assignTerm' :: MonadMetaSolver m => MetaId -> [Arg ArgName] -> Term -> m () Source #

Directly instantiate the metavariable. Skip pattern check, occurs check and frozen check. Used for eta expanding frozen metas.

etaExpandMeta :: [MetaKind] -> MetaId -> m () Source #

Eta expand a metavariable, if it is of the specified kind. Don't do anything if the metavariable is a blocked term.

updateMetaVar :: MetaId -> (MetaVariable -> MetaVariable) -> m () Source #

Update the status of the metavariable

speculateMetas :: m () -> m KeepMetas -> m () Source #

'speculateMetas fallback m' speculatively runs `m`, but if the result is `RollBackMetas` any changes to metavariables are rolled back and `fallback` is run instead.

To find the second one we need to look up the meta listeners for the one in the UnBlock constraint.
