Language.Haskell.Exts.Parser

Annotated parser for Haskell with extensions.

General parsing

class Parseable ast where

Class providing function for parsing at many different types.

Note that for convenience of implementation, the default methods have definitions equivalent to undefined. The minimal definition is all of the visible methods.

data ParseMode

Static parameters governing a parse. Note that the various parse functions in Language.Haskell.Exts.Parser never look at LANGUAGE pragmas, regardless of what the ignoreLanguagePragmas flag is set to. Only the various parseFile functions in Language.Haskell.Exts will act on it, when set to False.

Constructors

ParseMode

Fields

• parseFilename :: String

  original name of the file being parsed

• baseLanguage :: Language

  base language (e.g. Haskell98, Haskell2010)

• extensions :: [Extension]

  list of extensions enabled for parsing

• ignoreLanguagePragmas :: Bool

  if True, the parser won't care about further extensions in LANGUAGE pragmas in source files

• ignoreLinePragmas :: Bool

  if True, the parser won't read line position information from LINE pragmas in source files

• fixities :: Maybe [Fixity]

  list of fixities to be aware of

• ignoreFunctionArity :: Bool

  Checks whether functions have a consistent arity

Non-greedy parsers

newtype NonGreedy a

Instances of Parseable for NonGreedy a will only consume the input until a is fully parsed. This means that parse errors that come later in the input will be ignored. It's also more efficient, as it's fully lazy in the remainder of the input:

>>> parse (unlines ("module A where" : "main =" : repeat "blah")) :: ParseResult PragmasAndModuleHead
ParseOk (NonGreedy {unNonGreedy = PragmasAndModuleHead [] (ModuleName "A",Nothing,Nothing)})

(this example uses the simplified AST)

getTopPragmas :: String -> ParseResult [ModulePragma SrcSpanInfo]

data PragmasAndModuleName l

Type intended to be used with Parseable, with instances that implement a non-greedy parse of the module name, including top-level pragmas. This means that a parse error that comes after the module header won't be returned. If the Maybe value is Nothing, then this means that there was no module header.
