support for flow comment syntax

What version are you using? v2.10.2

What did you do? Flow supports the comment syntax, such as

/*: variable type */

What happened? However, writing it as such will cause an error with the spaced-comment rule

 Expected space or tab after '/*' in comment. (spaced-comment)

What did you expect to happen? Should eslint be able to detect the file using flow (with the header /* @flow */ and relax this error?

@tnguyen14 You problem is basically using off-the-shelf eslint wrapper. Those wrappers are specifically made to be easy to use, but provide no ability to customize configuration. You have two choices, either you can request a change to spaced-comments rule configuration from the happiness team, or you can stop using the wrapper and use their shareable eslint config and eslint itself without the wrapper.

In both cases this is not an issue with ESLint itself, but with the wrapper application. So closing this issue, since there’s nothing we can do about this, and @platinumazure already provided a correct workaround.

I’m not sure we even need to do anything here. @tnguyen14 Have you tried using the "markers" option in the spaced-comment rule? If you simply specify ":" as a marker, then the rule shouldn’t trigger for Flow comments.
