parsec

Commonly used character parsers.

module Text.ParserCombinators.Parsec.Char

parsec

Parsec compatibility module

char :: Stream s m Char => Char -> ParsecT s u m Char

parsec Text.Parsec.Char Text.ParserCombinators.Parsec.Char

char c parses a single character c. Returns the parsed character (i.e. c).

semiColon  = char ';'

type CharParser st = GenParser Char st

parsec Text.ParserCombinators.Parsec.Char

charLiteral :: GenTokenParser s u m -> ParsecT s u m Char

parsec Text.Parsec.Token Text.ParserCombinators.Parsec.Token

This lexeme parser parses a single literal character. Returns the literal character value. This parsers deals correctly with escape sequences. The literal character is parsed according to the grammar rules defined in the Haskell report (which matches most programming languages quite closely).

anyChar :: Stream s m Char => ParsecT s u m Char

parsec Text.Parsec.Char Text.ParserCombinators.Parsec.Char

This parser succeeds for any character. Returns the parsed character.

updatePosChar :: SourcePos -> Char -> SourcePos

parsec Text.Parsec.Pos Text.ParserCombinators.Parsec.Pos

Update a source position given a character. If the character is a newline ('\n') or carriage return ('\r') the line number is incremented by 1. If the character is a tab ('t') the column number is incremented to the nearest 8'th column, ie. column + 8 - ((column-1) `mod` 8). In all other cases, the column is incremented by 1.
