hi @lijunle
Thanks for the rule and taking the time to submit this.

One note: eslint-plugin-react is an MIT licensed project. So if we copy and paste a regular expression from that project to ours then we need to declare the project in our copyright notice and give proper credit. I would prefer to have zero dependencies, so I will rewrite this regular expression.

Another note: the build is failing because the rule is not documented in readme.md and there is no metadata.

Lastly, I will add some unit tests.

Thanks for the submission! I will try to merge this today.

Alright, I added tests and actually fixed an edge case. it all looks good. Thanks!

[lijunle]

Super thank you for handling this! You are awesome!

[HamletDRC]

Well, thanks for the PR!

In the future, if you create a rule be sure to use:

grunt create-rule my-rule-name

Then it generates tests and documentation for you :)
