allMetas' :: (TermLike a, Monoid m) => (MetaId -> m) -> a -> m Source #

allMetasList :: AllMetas a => a -> [MetaId] Source #

Returns `allMetas` in a list. `allMetasList = allMetas (:[])`.

Note: this resulting list is computed via difference lists. Thus, use this function if you actually need the whole list of metas. Otherwise, use `allMetas` with a suitable monoid.

noMetas :: AllMetas a => a -> Bool Source #

`True` if thing contains no metas. `noMetas = null . allMetasList`.

firstMeta :: AllMetas a => a -> Maybe MetaId Source #

Returns the first meta it find in the thing, if any. `firstMeta == listToMaybe . allMetasList`.

unblockOnAnyMetaIn :: AllMetas t => t -> Blocker Source #

A blocker that unblocks if any of the metas in a term are solved.

unblockOnAllMetasIn :: AllMetas t => t -> Blocker Source #

A blocker that unblocks if any of the metas in a term are solved.
