[vikingair]

Please describe what the rule should do: When v-on: and v-bind: are being used the rule should complain and suggest (even autofix) these with the respective shortcuts @ and :. Exceptions are of course usages without specified keys e.g. v-bind="...".

What category should the rule belong to? [x] Enforces code style (layout) [ ] Warns about a potential error (problem) [ ] Suggests an alternate way of doing something (suggestion) [ ] Other (please specify:)

Provide 2-3 code examples that this rule should warn about:

<MyComponent

<!-- should be -->
<MyComponent
  :num="2"
  @click="handleClick"
/>
