Emit on parse error

[ArmorDarks]

So far if Gray Matter encounters Matter block, but unable to parse it (let's say, due to wrong escaping), it silently ignores it and outputs empty file.

It would be much better if Gray Matter instead emitted some event, so we can hook on it and log warning about invalid syntax, etc.

I agree, we need to completely refactor how the parsers work. I'll try to spend some time on this as soon as I have a chance

Well, for YAML js-yaml already should throw an error if it encounters syntax error. However, gray-matter seems to swallowing that error somewhere.

If it could be passed as a callback (error) => do something with me, it would solve the issue.

Another way would be a simple option like opts.throwOnParseError, which will force exception in case of parsing error.

this was resolved in 3.0

Wow, cool! I've totally missed new release. Thanks a lot!
