Lenses

valuecommentStart

:: Functor f
=> String -> f String
-> CommentStyle
-> f CommentStyle

Source#

This is a lens that can edit the string that starts a multiline comment.

commentStart :: Lens' CommentStyle String

valuecommentEnd

:: Functor f
=> String -> f String
-> CommentStyle
-> f CommentStyle

Source#

This is a lens that can edit the string that ends a multiline comment.

commentEnd :: Lens' CommentStyle String

valuecommentLine

:: Functor f
=> String -> f String
-> CommentStyle
-> f CommentStyle

Source#

This is a lens that can edit the string that starts a single line comment.

commentLine :: Lens' CommentStyle String

valuecommentNesting

:: Functor f
=> Bool -> f Bool
-> CommentStyle
-> f CommentStyle

Source#

This is a lens that can edit whether we can nest multiline comments.

commentNesting :: Lens' CommentStyle Bool

Common Comment Styles

valueemptyCommentStyle :: CommentStyle

Source#

No comments at all

valuejavaCommentStyle :: CommentStyle

Source#

Use java-style comments

valuescalaCommentStyle :: CommentStyle

Source#

Use scala-style comments

valuehaskellCommentStyle :: CommentStyle

Source#

Use haskell-style comments

valuebuildSomeSpaceParser :: CharParsing m => m () -> CommentStyle -> m ()

Source#

Use this to easily build the definition of whiteSpace for your MonadParser given a comment style and an underlying someWhiteSpace parser

Identifier Styles

valueemptyIdents :: TokenParsing m => IdentifierStyle m

Source#

A simple identifier style based on haskell with no reserve words

valuehaskellIdents :: TokenParsing m => IdentifierStyle m

Source#

A simple identifier style based on haskell with the reserved words from Haskell 98 and some common extensions.

valuehaskell98Idents :: TokenParsing m => IdentifierStyle m

Source#

A simple identifier style based on haskell with only the reserved words from Haskell 98.

Operator Styles

valueemptyOps :: TokenParsing m => IdentifierStyle m

Source#

A simple operator style based on haskell with no reserved operators

valuehaskellOps :: TokenParsing m => IdentifierStyle m

Source#

A simple operator style based on haskell with the operators from Haskell 98.

valuehaskell98Ops :: TokenParsing m => IdentifierStyle m

Source#

A simple operator style based on haskell with the operators from Haskell 98.
