Documentation
class Show a => StringTemplateShows a where Source
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.
Minimal complete definition
Nothing
Methods
stringTemplateShow :: a -> String Source
Defaults to show.
stringTemplateFormattedShow :: String -> a -> String Source
Defaults to _ a -> stringTemplateShow a
The ToSElem class should be instantiated for all types that can be inserted as attributes into a StringTemplate.
Minimal complete definition
Methods
toSElem :: Stringable b => a -> SElem b Source
toSElemList :: Stringable b => [a] -> SElem b Source

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