Yeah, not all rules are fixable.
If you want a rule to fix code automatically, please make a concrete proposal for each rule.

[casprwang]

@mysticatea thanks for responding, do you know if those rules could be fixable in the future, or on a plan?

[mysticatea]

There is no plan. Changes will come based on issues since issues are consideration or requests on Vue community.

A volunteer works on vue/max-attributes-per-line (#380)

[casprwang]

Thanks for clarifying, I hope that PR would be merged soon. It would be awesome to fix vue/max-attributes-per-line
