Synopsis

Comment and white space styles

data CommentStyle Source #

How to deal with comments.

Constructors

CommentStyle
Fields _commentStart :: String String that starts a multiline comment _commentEnd :: String String that ends a multiline comment _commentLine :: String String that starts a single line comment _commentNesting :: Bool Can we nest multiline comments?

Lenses

commentStart :: 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

commentEnd :: 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

commentLine :: 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

commentNesting :: 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

emptyCommentStyle :: CommentStyle Source #

No comments at all

javaCommentStyle :: CommentStyle Source #

Use java-style comments

scalaCommentStyle :: CommentStyle Source #

Use scala-style comments

haskellCommentStyle :: CommentStyle Source #

Use haskell-style comments

buildSomeSpaceParser :: forall m. 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

emptyIdents :: TokenParsing m => IdentifierStyle m Source #

A simple identifier style based on haskell with no reserve words

haskellIdents :: TokenParsing m => IdentifierStyle m Source #

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

haskell98Idents :: TokenParsing m => IdentifierStyle m Source #

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

Operator Styles

emptyOps :: TokenParsing m => IdentifierStyle m Source #

A simple operator style based on haskell with no reserved operators

haskellOps :: TokenParsing m => IdentifierStyle m Source #

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

haskell98Ops :: TokenParsing m => IdentifierStyle m Source #

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