1. maybestringopt :: String -> RawOpts -> Maybe String

   hledger-lib	Hledger.Data.RawOptions

   No documentation available.

2. maybeynaopt :: String -> RawOpts -> Maybe YNA

   hledger-lib	Hledger.Data.RawOptions

   No documentation available.

3. maybeynopt :: String -> RawOpts -> Maybe Bool

   hledger-lib	Hledger.Data.RawOptions

   No documentation available.

4. maybeNullOrUndefined :: ToJSVal value => value -> JSM (Maybe JSVal)

   jsaddle	Language.Javascript.JSaddle.Value

   Convert a JSVal to a Maybe JSVal (converting null and undefined to Nothing)

5. maybeNullOrUndefined' :: ToJSVal value => (JSVal -> JSM a) -> value -> JSM (Maybe a)

   jsaddle	Language.Javascript.JSaddle.Value

   No documentation available.

6. maybeCompatible :: Eq a => T a -> T a -> Maybe a

   numeric-prelude	Number.ResidueClass.Check

   No documentation available.

7. maybePositive :: (Additive a, MeetSemiLattice a) => a -> Maybe (Positive a)

   numhask	NumHask.Data.Positive

   Constructor which returns Nothing if a negative number is supplied.

   >>> maybePositive (-one)
   Nothing
   

8. maybeToList :: Maybe a -> [a]

   basic-prelude	CorePrelude

   The maybeToList function returns an empty list when given Nothing or a singleton list when given Just.

   Examples

   Basic usage:

   >>> maybeToList (Just 7)
   [7]
   

   >>> maybeToList Nothing
   []
   

   One can use maybeToList to avoid pattern matching when combined with a function that (safely) works on lists:

   >>> import GHC.Internal.Text.Read ( readMaybe )
   
   >>> sum $ maybeToList (readMaybe "3")
   3
   
   >>> sum $ maybeToList (readMaybe "")
   0
   

9. maybeSelectCurrentEntry :: EventM n (FileBrowser n) ()

   brick	Brick.Widgets.FileBrowser

   If the browser's current entry is selectable according to fileBrowserSelectable, add it to the selection set and return. If not, and if the entry is a directory or a symlink targeting a directory, set the browser's current path to the selected directory. Otherwise, return the browser state unchanged.

10. maybeToList :: Maybe a -> [a]

    classy-prelude	ClassyPrelude

    The maybeToList function returns an empty list when given Nothing or a singleton list when given Just.

    Examples

    Basic usage:

    >>> maybeToList (Just 7)
    [7]
    

    >>> maybeToList Nothing
    []
    

    One can use maybeToList to avoid pattern matching when combined with a function that (safely) works on lists:

    >>> import GHC.Internal.Text.Read ( readMaybe )
    
    >>> sum $ maybeToList (readMaybe "3")
    3
    
    >>> sum $ maybeToList (readMaybe "")
    0
