I noticed that we can also now remove this line from cpp_style_unittest.py:

> from checker import CategoryFilter

I'll do that after the review.

Looks a sane code migration.

> -    def __init__(self, output_format, verbosity=1, filter=None,
> +    def __init__(self, output_format="emacs", verbosity=1, filter=None,

I think we can utilize DEFAULT_OUTPUT_FORMAT and DEFAULT_VERBOSITY?

> +        if ((verbosity < 1) or (verbosity > 5)):

I think we usually don't have parentheses for the condition of if-statement, but I don't care. Please remove them if you have no preference about this.

> +        ProcessorOptions() # No ValueError: works

I slightly prefer to examine the constructed value if it has sane attributes.

> +        # Spurious white space in filter rules.
> +        (files, options) = parse(['--filter=+foo ,-bar'])
> +        self.assertEquals(options.filter,
> +                          CategoryFilter(["-", "+whitespace", "+foo", "-bar"]))

Thanks for adding this!

Thanks for the quick review, Shinichiro!  Submitting patch for cq shortly.

The default parameter values above are meant more for convenience and internal use (like unit testing) rather than to be substantive.  That is why, for example, the default filter here should be the empty rule rather than the global variable list of filter rules for check-webkit-style.  Maybe in a future patch I can rename the DEFAULT values to something like SCRIPT_DEFAULT_OUTPUT_FORMAT to make clearer the distinction that those global variable defaults are for use by check-webkit-style.

Thanks for the catch.  I also made this same change in a second place in the file.

Good suggestion.  Done.

Thanks for the description and fixing issues. I've found you fixed s/self.handle_error/self._handle_error/ . Thanks for catching this issue and sorry I didn't notice it. I think this means we want StyleCheckerTest later. Could you work for this? Otherwise, I'll write it.

I wasn't planning on doing it soon.  If you could do it, that would be great.  Thanks.
