Documentation

haskellDef :: LanguageDef stSource

The language definition for the Haskell language.

haskell :: TokenParser stSource

A lexer for the haskell language.

mondrianDef :: LanguageDef stSource

The language definition for the language Mondrian.

mondrian :: TokenParser stSource

A lexer for the mondrian language.

haskellStyle :: LanguageDef stSource

This is a minimal token definition for Haskell style languages. It defines the style of comments, valid identifiers and case sensitivity. It does not define any reserved words or operators.

javaStyle :: LanguageDef stSource

This is a minimal token definition for Java style languages. It defines the style of comments, valid identifiers and case sensitivity. It does not define any reserved words or operators.

Fields

commentStart :: String

Describes the start of a block comment. Use the empty string if the language doesn't support block comments. For example "/*".

commentEnd :: String

Describes the end of a block comment. Use the empty string if the language doesn't support block comments. For example "*/".

commentLine :: String

Describes the start of a line comment. Use the empty string if the language doesn't support line comments. For example "//".

nestedComments :: Bool

Set to True if the language supports nested block comments.

identStart :: ParsecT s u m Char

This parser should accept any start characters of identifiers. For example letter <|> char "_".

identLetter :: ParsecT s u m Char

This parser should accept any legal tail characters of identifiers. For example alphaNum <|> char "_".

opStart :: ParsecT s u m Char

This parser should accept any start characters of operators. For example oneOf ":!#$%&*+./<=>?@\\^|-~"

opLetter :: ParsecT s u m Char

This parser should accept any legal tail characters of operators. Note that this parser should even be defined if the language doesn't support user-defined operators, or otherwise the reservedOp parser won't work correctly.

reservedNames :: [String]

The list of reserved identifiers.

reservedOpNames :: [String]

The list of reserved operators.

caseSensitive :: Bool

Set to True if the language is case sensitive.
