Description
This module provides a way to specify a grammar of .cabal -like files.
Synopsis
- class FieldGrammar g where
- uniqueField :: (FieldGrammar g, Parsec a, Pretty a) => FieldName -> ALens' s a -> g s a
- optionalField :: (FieldGrammar g, Parsec a, Pretty a) => FieldName -> ALens' s (Maybe a) -> g s (Maybe a)
- optionalFieldDef :: (FieldGrammar g, Functor (g s), Parsec a, Pretty a, Eq a) => FieldName -> ALens' s a -> a -> g s a
- monoidalField :: (FieldGrammar g, Parsec a, Pretty a, Monoid a) => FieldName -> ALens' s a -> g s a
- deprecatedField' :: FieldGrammar g => String -> g s a -> g s a
- data ParsecFieldGrammar s a
- type ParsecFieldGrammar' a = ParsecFieldGrammar a a
- parseFieldGrammar :: CabalSpecVersion -> Fields Position -> ParsecFieldGrammar s a -> ParseResult a
- fieldGrammarKnownFieldList :: ParsecFieldGrammar s a -> [FieldName]
- data PrettyFieldGrammar s a
- type PrettyFieldGrammar' a = PrettyFieldGrammar a a
- prettyFieldGrammar :: PrettyFieldGrammar s a -> s -> Doc
- (^^^) :: a -> (a -> b) -> b
- data Section ann = MkSection !(Name ann) [SectionArg ann] [Field ann]
- type Fields ann = Map FieldName [NamelessField ann]
- partitionFields :: [Field ann] -> (Fields ann, [[Section ann]])
- takeFields :: [Field ann] -> (Fields ann, [Field ann])
- runFieldParser :: Position -> ParsecParser a -> CabalSpecVersion -> [FieldLine Position] -> ParseResult a
- runFieldParser' :: Position -> ParsecParser a -> CabalSpecVersion -> FieldLineStream -> ParseResult a
Field grammar type
class FieldGrammar g where Source #
FieldGrammar is parametrised by
swhich is a structure we are parsing. We need this to provide prettyprinter functionalityatype 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.
Arguments
| :: (Parsec b, Pretty b, Newtype b a) | |
| => FieldName | field name |
| -> (a -> b) |
|
| -> ALens' s a | lens into the field |
| -> g s a |
Field which should be defined, exactly once.
Boolean field with a default value.
Arguments
| :: (Parsec b, Pretty b, Newtype b a) | |
| => FieldName | field name |
| -> (a -> b) |
|
| -> ALens' s (Maybe a) | lens into the field |
| -> g s (Maybe a) |
Optional field.
Arguments
| :: (Parsec b, Pretty b, Newtype b a, Eq a) | |
| => FieldName | field name |
| -> (a -> b) |
|
| -> ALens' s a |
|
| -> a | default value |
| -> g s a |
Optional field with default value.
Arguments
| :: (Parsec b, Pretty b, Monoid a, Newtype b a) | |
| => FieldName | field name |
| -> (a -> b) |
|
| -> 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.
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.
Field which is parsed but not pretty printed.
Deprecated since
Arguments
| :: [Int] | spec version |
| -> a | default value |
| -> g s a | |
| -> g s a |
Annotate field with since spec-version.
Instances
Arguments
| :: (FieldGrammar g, Parsec a, Pretty a) | |
| => FieldName | field name |
| -> ALens' s a | lens into the field |
| -> g s a |
Field which can be defined at most once.
Arguments
| :: (FieldGrammar g, Parsec a, Pretty a) | |
| => FieldName | field name |
| -> ALens' s (Maybe a) | lens into the field |
| -> g s (Maybe a) |
Field which can be defined at most once.
Arguments
| :: (FieldGrammar g, Functor (g s), Parsec a, Pretty a, Eq a) | |
| => FieldName | field name |
| -> ALens' s a |
|
| -> a | default value |
| -> g s a |
Optional field with default value.
Arguments
| :: (FieldGrammar g, Parsec a, Pretty a, Monoid a) | |
| => FieldName | field name |
| -> ALens' s a | lens into the field |
| -> g s a |
Field which can be define multiple times, and the results are mappended.
Arguments
| :: FieldGrammar g | |
| => String | deprecation message |
| -> g s a | |
| -> g s a |
Deprecated field. If found, warning is issued.
Note: also it's not pretty printed!
Concrete grammar implementations
data ParsecFieldGrammar s a Source #
Instances
type ParsecFieldGrammar' a = ParsecFieldGrammar a a Source #
parseFieldGrammar :: CabalSpecVersion -> Fields Position -> ParsecFieldGrammar s a -> ParseResult a Source #
fieldGrammarKnownFieldList :: ParsecFieldGrammar s a -> [FieldName] Source #
data PrettyFieldGrammar s a Source #
Instances
type PrettyFieldGrammar' a = PrettyFieldGrammar a a Source #
prettyFieldGrammar :: PrettyFieldGrammar s a -> s -> Doc Source #
We can use PrettyFieldGrammar to pp print the s.
Note: there is not trailing ($+$ text "").
Auxlilary
(^^^) :: a -> (a -> b) -> b infixl 5 Source #
Reverse function application which binds tighter than <$> and <*>.
Useful for refining grammar specification.
