1. boolReader :: (Eq a, Show a, FoldCase a, IsString a, IsString e, Monoid e) => a -> Either e Bool

   configuration-tools	Configuration.Utils.CommandLine

   No documentation available.

2. boolToGauge :: Bool -> Metric

   data-prometheus	Data.Prometheus.Monad

   Convert Bool to Gauge, 0 meaning False

3. boolFlag :: Name -> Description -> FlagsParser Bool

   flags-applicative	Flags.Applicative

   Returns a parser with the given name and description for a flag with no value, returning whether the flag was present.

4. boolL :: Bool -> r -> r -> r

   generic-case	Generics.Case

   Same as bool, except the Bool comes before the case functions. Equivalent type signature:

   boolL :: forall r. Analysis Bool r
   

   The implementation is just:

   boolL = gcase
   

5. boolR :: r -> r -> Bool -> r

   generic-case	Generics.Case

   bool, implemented using gcaseR. Equivalent type signature:

   boolR :: forall r. AnalysisR Bool r
   

   The implementation is just:

   boolR = gcaseR @Bool
   

6. boolector :: GrisetteSMTConfig

   grisette	Grisette.Backend

   Solver configuration for Boolector. https://boolector.github.io/

7. boolector :: GrisetteSMTConfig

   grisette	Grisette.Internal.Backend.Solving

   Solver configuration for Boolector. https://boolector.github.io/

8. boolField :: String -> (Item a -> Bool) -> Context a

   hakyll	Hakyll.Web.Template.Context

   Creates a field to use with the $if()$ template macro. Attempting to substitute the field into the template will cause an error.

9. boolFieldM :: String -> (Item a -> Compiler Bool) -> Context a

   hakyll	Hakyll.Web.Template.Context

   Creates a field to use with the $if()$ template macro, in the Compiler monad. Attempting to substitute the field into the template will cause an error.

10. boolField :: forall (m :: Type -> Type) . (Monad m, RenderMessage (HandlerSite m) FormMessage) => Field m Bool

    hledger-web	Hledger.Web.Import

    Creates a group of radio buttons to answer the question given in the message. Radio buttons are used to allow differentiating between an empty response (Nothing) and a no response (Just False). Consider using the simpler checkBoxField if you don't need to make this distinction. If this field is optional, the first radio button is labeled "<None>", the second "Yes" and the third "No". If this field is required, the first radio button is labeled "Yes" and the second "No". (Exact label titles will depend on localization).
