1. showFirstCursor :: s -> [CursorLocation n] -> Maybe (CursorLocation n)

   brick	Brick.Main

   Always show the first cursor, if any, returned by the rendering process. This is a convenience function useful as an appChooseCursor value when a simple program has zero or more widgets that advertise a cursor position.

2. listFindFirst :: forall (t :: Type -> Type) e n . (Semigroup (t e), Splittable t, Traversable t) => (e -> Bool) -> GenericList n t e -> Maybe (Int, e)

   brick	Brick.Widgets.List

   Find the first element in the list that satisfies the specified predicate. If such an element is found, return the resulting index and element. O(n).

3. selectFirst :: forall (m :: Type -> Type) record . (PersistQueryRead backend, MonadIO m, PersistRecordBackend record backend) => [Filter record] -> [SelectOpt record] -> ReaderT backend m (Maybe (Entity record))

   esqueleto	Database.Esqueleto

   Get just the first record for the criterion.

4. class GetFirstTable t ts

   esqueleto	Database.Esqueleto.Experimental

   Typeclass for selecting tables using type application syntax. If you have a long chain of tables joined with (:&), like a :& b :& c :& d, then getTable @c (a :& b :& c :& d) will give you the c table back. Note that this typeclass will only select the first table of the given type; it may be less useful if there's multiple tables of the same type.

5. getFirstTable :: GetFirstTable t ts => ts -> t

   esqueleto	Database.Esqueleto.Experimental

   Get the first table of type t from the tables ts.

6. selectFirst :: forall (m :: Type -> Type) record . (PersistQueryRead backend, MonadIO m, PersistRecordBackend record backend) => [Filter record] -> [SelectOpt record] -> ReaderT backend m (Maybe (Entity record))

   esqueleto	Database.Esqueleto.Experimental

   Get just the first record for the criterion.

7. class GetFirstTable t ts

   esqueleto	Database.Esqueleto.Experimental.From.Join

   Typeclass for selecting tables using type application syntax. If you have a long chain of tables joined with (:&), like a :& b :& c :& d, then getTable @c (a :& b :& c :& d) will give you the c table back. Note that this typeclass will only select the first table of the given type; it may be less useful if there's multiple tables of the same type.

8. getFirstTable :: GetFirstTable t ts => ts -> t

   esqueleto	Database.Esqueleto.Experimental.From.Join

   Get the first table of type t from the tables ts.

9. selectFirst :: forall (m :: Type -> Type) record . (PersistQueryRead backend, MonadIO m, PersistRecordBackend record backend) => [Filter record] -> [SelectOpt record] -> ReaderT backend m (Maybe (Entity record))

   esqueleto	Database.Esqueleto.Legacy

   Get just the first record for the criterion.

10. ascNullsFirst :: PersistField a => SqlExpr (Value a) -> SqlExpr OrderBy

    esqueleto	Database.Esqueleto.PostgreSQL

    Ascending order of this field or SqlExpression with nulls coming first.
