Parsers

satisfy : (Char -> Bool) -> Parser Char

Parse a character matching the predicate.

parse (satisfy ((==) 'a')) "a" ==
  (Ok 'a', { input = "", position = 1 })


parse (satisfy ((==) 'a')) "b" ==
  (Err ["could not satisfy predicate"], { input = "b", position = 0 })

char : Char -> Parser Char

Parse an exact character match.

parse (char 'a') "a" ==
  (Ok 'a', { input = "", position = 1 })


parse (char 'a') "b" ==
  (Err ["expected 'a'"], { input = "b", position = 0 })

anyChar : Parser Char

Parse any character.

parse anyChar "a" ==
  (Ok 'a', { input = "", position = 1 })


parse anyChar "" ==
  (Err ["expected any character"], { input = "", position = 0 })

oneOf : List Char -> Parser Char

Parse a character from the given list.

parse (oneOf ['a', 'b']) "a" ==
  (Ok 'a', { input = "", position = 1 })


parse (oneOf ['a', 'b']) "c" ==
  (Err ["expected one of ['a','b']"], { input = "c", position = 0 })

noneOf : List Char -> Parser Char

Parse a character that is not in the given list.

parse (noneOf ['a', 'b']) "c" ==
  (Ok 'c', { input = "", position = 1 })


parse (noneOf ['a', 'b']) "a" ==
