Add separate linters for Objective-C/Objective C++.

[davidaurelio]

This adds two extra linters that apply to Objective-C/C++ code.

I have added -fobjc-arc as compiler arg to make the __has_feature(objc_arc) preprocessor test pass. Automatic reference counting (arc) should be the default in most Objective-C projects these days.

It would have been cool to add support for module imports (@import CoreGraphics), but unfortunately this requires more extensive command line flags that might be machine specific. So I left it out.

Very nice.

I think we can omit "multiline = True" because we already compile the regex with that flag, and SublimeLinter should read the used flags.

I would not have extracted the default args to a pseudo constant. Do you think that's easier to read or modify? I usually read these linter classes as declarations. SublimeLinter doesn't allow inheritance here as well which is probably not a bad limitation. Feel free to leave it as is.

Sounds good, let me remove it.

I guess that’s more the reflex of de-duplicating. Let me inline it, I don’t feel strongly about it at all.

I will actually give the multiline change a quick try on my work code base tomorrow to make sure it works.

@kaste removing multiline = True stops errors from #include being flagged. You know better about the internals.

[kaste]

Oh, my bad. I misremembered it. We only set "multiline" automatically if "regex" is a string with inline flags. You know, these flags: (?m)foo.*. 🤷‍♀️

Can I pull and release, or do you want another minute?

[davidaurelio]

Pull and release, please :-) I will have another look into how errors of included files are reported soon.
