Documentation
class Show a => StringTemplateShows a whereSource
The StringTemplateShows class should be instantiated for all types that are directly displayed in a StringTemplate, but take an optional format string. Each such type must have an appropriate ToSElem method defined as well.
Methods
stringTemplateShow :: a -> StringSource
Defaults to show.
stringTemplateFormattedShow :: String -> a -> StringSource
Defaults to _ a -> stringTemplateShow a
The ToSElem class should be instantiated for all types that can be inserted as attributes into a StringTemplate.
Methods
toSElem :: Stringable b => a -> SElem bSource
toSElemList :: Stringable b => [a] -> SElem bSource

class Monoid a => Stringable a whereSource
The Stringable class should be instantiated with care. Generally, the provided instances should be enough for anything.
Methods
stFromString :: String -> aSource
stFromByteString :: ByteString -> aSource
stFromText :: Text -> aSource
stToString :: a -> StringSource
mconcatMap :: [b] -> (b -> a) -> aSource
Defaults to mconcatMap m k = foldr (mappend . k) mempty m
mintercalate :: a -> [a] -> aSource
Defaults to (mconcat .) . intersperse
stShowsToSE :: (StringTemplateShows a, Stringable b) => a -> SElem bSource
This method should be used to create ToSElem instances for types defining a custom formatted show function.
