Methods

fold :: Monoid m => PrettyField m -> m #

foldMap :: Monoid m => (a -> m) -> PrettyField a -> m #

foldMap' :: Monoid m => (a -> m) -> PrettyField a -> m #

foldr :: (a -> b -> b) -> b -> PrettyField a -> b #

foldr' :: (a -> b -> b) -> b -> PrettyField a -> b #

foldl :: (b -> a -> b) -> b -> PrettyField a -> b #

foldl' :: (b -> a -> b) -> b -> PrettyField a -> b #

foldr1 :: (a -> a -> a) -> PrettyField a -> a #

foldl1 :: (a -> a -> a) -> PrettyField a -> a #

toList :: PrettyField a -> [a] #

null :: PrettyField a -> Bool #

length :: PrettyField a -> Int #

elem :: Eq a => a -> PrettyField a -> Bool #

maximum :: Ord a => PrettyField a -> a #

minimum :: Ord a => PrettyField a -> a #

sum :: Num a => PrettyField a -> a #

Traversable PrettyField Source # 
Instance details

Defined in Distribution.Fields.Pretty

Methods

traverse :: Applicative f => (a -> f b) -> PrettyField a -> f (PrettyField b) #

sequenceA :: Applicative f => PrettyField (f a) -> f (PrettyField a) #

mapM :: Monad m => (a -> m b) -> PrettyField a -> m (PrettyField b) #

sequence :: Monad m => PrettyField (m a) -> m (PrettyField a) #

showFields :: (ann -> [String]) -> [PrettyField ann] -> String Source #

Prettyprint a list of fields.

Note: the first argument should return Strings without newlines and properly prefixes (with --) to count as comments. This unsafety is left in place so one could generate empty lines between comment lines.

showFields' Source #

Arguments

:: (ann -> [String])

Convert an annotation to lined to preceed the field or section.

-> (ann -> [String] -> [String])

Post-process non-annotation produced lines.

-> Int

Indentation level.

-> [PrettyField ann]

Fields/sections to show.

-> String 

showFields with user specified indentation.

Transformation from Field

fromParsecFields :: [Field ann] -> [PrettyField ann] Source #

Simple variant of genericFromParsecField

genericFromParsecFields Source #

Arguments

:: Applicative f 
=> (FieldName -> [FieldLine ann] -> f Doc)

transform field contents

-> (FieldName -> [SectionArg ann] -> f [Doc])

transform section arguments

-> [Field ann] 
-> f [PrettyField ann] 

prettyFieldLines :: FieldName -> [FieldLine ann] -> Doc Source #

Used in fromParsecFields.

prettySectionArgs :: FieldName -> [SectionArg ann] -> [Doc] Source #

Used in fromParsecFields.
