        Context manager to be used when writing unit tests that modify pyparsing config values:
        - packrat parsing
        - bounded recursion parsing
        - default whitespace characters.
        - default keyword characters
        - literal string auto-conversion class
        - __diag__ settings

        Example::

            with reset_pyparsing_context():
                # test that literals used to construct a grammar are automatically suppressed
                ParserElement.inlineLiteralsUsing(Suppress)

                term = Word(alphas) | Word(nums)
                group = Group('(' + term[...] + ')')

                # assert that the '()' characters are not included in the parsed tokens
                self.assertParseAndCheckList(group, "(abc 123 def)", ['abc', '123', 'def'])

            # after exiting context manager, literals are converted to Literal expressions again

        Helpful method for debugging a parser - prints a string with line and column numbers.
        (Line and column numbers are 1-based.)

        :param s: tuple(bool, str - string to be printed with line and column numbers
        :param start_line: int - (optional) starting line number in s to print (default=1)
        :param end_line: int - (optional) ending line number in s to print (default=len(s))
        :param expand_tabs: bool - (optional) expand tabs to spaces, to match the pyparsing default
        :param eol_mark: str - (optional) string to mark the end of lines, helps visualize trailing spaces (default="|")
        :param mark_spaces: str - (optional) special character to display in place of spaces
        :param mark_control: str - (optional) convert non-printing control characters to a placeholding
                                 character; valid values:
                                 - "unicode" - replaces control chars with Unicode symbols, such as "␍" and "␊"
                                 - any single character string - replace control characters with given string
                                 - None (default) - string is displayed as-is

        :return: str - input string with leading line numbers and column number headers
