Agda.Syntax.Parser

Synopsis

Types

data Parser a Source #

Wrapped Parser type.

Parse functions

parse :: Parser a -> String -> PM (a, Attributes) Source #

Parse without top-level layout.

parsePosString :: Parser a -> Position -> String -> PM (a, Attributes) Source #

parseFile Source #

Arguments

:: Show a 
=> Parser a 
-> RangeFile

The file.

-> String

The file contents. Note that the file is not read from disk.

-> PM ((a, Attributes), FileType) 

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 :: RangeFile -> PM Text Source #

Returns the contents of the given file.

Parse errors

data ParseError Source #

Parse errors: what you get if parsing fails.

Constructors
