LabelJust :: Justification -> Attributegraphviz Data.GraphViz.Attributes.Complete Valid for: GC; Default: JCenter
NoJustify :: Bool -> Attributegraphviz Data.GraphViz.Attributes.Complete adjustErr :: Commitment p => p a -> (String -> String) -> p agraphviz Data.GraphViz.Parsing p adjustErr f applies the transformation f to any error message generated in p, having no effect if p succeeds.
adjustErrBad :: PolyParse p => p a -> (String -> String) -> p agraphviz Data.GraphViz.Parsing adjustErrBad is just like adjustErr except it also raises the severity of the error.
adjustOption :: IsOption v => (v -> v) -> TestTree -> TestTreehledger-lib Hledger.Utils.Test Locally adjust the option value for the given test subtree.

Examples
Basic usage:>>> isJust (Just 3) True
>>> isJust (Just ()) True
>>> isJust Nothing False
Only the outer constructor is taken into consideration:>>> isJust (Just Nothing) True

adjust :: (MonadIO m, MonadMask m) => Store ctx -> (ctx -> ctx) -> m a -> m acontext Context Adjust the calling thread's context in the specified Store for the duration of the specified action. Throws a NotFoundException when the calling thread has no registered context.
withAdjusted :: (MonadIO m, MonadMask m) => Store ctx -> (ctx -> ctx) -> (ctx -> m a) -> m acontext Context Convenience function to adjust the context then supply the adjusted context to the inner action. This function is equivalent to calling adjust and then immediately calling mine in the inner action of adjust, e.g.:
doStuff :: Store Thing -> (Thing -> Thing) -> IO () doStuff store f = do adjust store f do adjustedThing <- mine store ...
Throws a NotFoundException when the calling thread has no registered context.
