Field grammar type

class FieldGrammar g where Source #

FieldGrammar is parametrised by

s which is a structure we are parsing. We need this to provide prettyprinter functionality
a type of the field.

Note: We'd like to have forall s. Applicative (f s) context.

Methods

blurFieldGrammar :: ALens' a b -> g b c -> g a c Source #

Unfocus, zoom out, blur FieldGrammar.

uniqueFieldAla Source #

Arguments

:: (Parsec b, Pretty b, Newtype a b)
=> FieldName	field name
-> (a -> b)	`Newtype` pack
-> ALens' s a	lens into the field
-> g s a

Field which should be defined, exactly once.

booleanFieldDef Source #

Arguments

:: FieldName	field name
-> ALens' s Bool	lens into the field
-> Bool	default
-> g s Bool

Boolean field with a default value.

-> (a -> b)	`pack`
-> ALens' s a	lens into the field
-> g s a

Monoidal field.

Values are combined with mappend.

Note: optionalFieldAla is a monoidalField with Last monoid.

prefixedFields Source #

Arguments

:: FieldName	field name prefix
-> ALens' s [(String, String)]	lens into the field
-> g s [(String, String)]

Parser matching all fields with a name starting with a prefix.

knownField :: FieldName -> g s () Source #

Known field, which we don't parse, neither pretty print.

hiddenField :: g s a -> g s a Source #

Field which is parsed but not pretty printed.

deprecatedSince Source #

Arguments

-> String	deprecation message
-> g s a
-> g s a

Deprecated since

removedIn Source #

Arguments

:: CabalSpecVersion	version
-> String	removal message

-> g s a

Removed in. If we occur removed field, parsing fails.

availableSince Source #

Arguments
