Types
Parse functions
Parsers
moduleParser :: Parser Module Source #
Parses a module.
moduleNameParser :: Parser QName Source #
Parses a module name.
acceptableFileExts :: [String] Source #
Extensions supported by parseFile.
exprParser :: Parser Expr Source #
Parses an expression.
exprWhereParser :: Parser ExprWhere Source #
Parses an expression followed by a where clause.
holeContentParser :: Parser HoleContent Source #
Parses an expression or some other content of an interaction hole.
tokensParser :: Parser [Token] Source #
Gives the parsed token stream (including comments).
Reading files.
readFilePM :: AbsolutePath -> PM Text Source #
Returns the contents of the given file.
Parse errors
data ParseError Source #
Parse errors: what you get if parsing fails.
