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

class ToSElem a where Source

The ToSElem class should be instantiated for all types that can be inserted as attributes into a StringTemplate.

Constructors

StFirst 

Fields

stGetFirst :: Maybe a
 

Instances

Functor StFirst

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

stFromString, stToString

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

mlabel :: a -> a -> a Source

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.
