Abstract Value Members

  1. abstract val whitespaceParser: PackratParser[Any]

    A parser that recognises whitespace.

    A parser that recognises whitespace. Normal whitespace handling is turned off while this parser is applied, since we need to avoid an infinite recursion if the form of whitespace is defined using literal or regex.

  38. def keywords(ext: Regex, kws: Seq[String]): Parser[String]

    Parser for keywords.

    Parser for keywords. The list of string arguments gives the text of the keywords in a language. The regular expression gives the possible extension of the keyword to stop the keyword being seen as an identifier instead. For example, the keyword list might contain "begin" and "end" and the extension regular expression might be [^a-zA-Z0-9]. Thus, begin followed by something other than a letter or digit is a keyword, but beginfoo8 is an identifier. This parser succeeds if any of the keywords is present, provided that it's not immediately followed by something that extends it.

    Wrap a parser p that produces a value of type T to produce a parser returning values of type U.

    Wrap a parser p that produces a value of type T to produce a parser returning values of type U. Whitespace is skipped (if we are skipping white space) before p is applied, so that we have access to the first non-whitespace position.

    The function f is responsible for converting the T value into either a U value or a string that indicates what went wrong. In the latter case, the resulting parser will error at the original position with the message, ignoring any other errors at that position. Failures or errors of p will be lifted to the returned type.
