var matchFirstCap = regexp.MustCompile("(.)([A-Z][a-z]+)")
var matchAllCap   = regexp.MustCompile("([a-z0-9])([A-Z])")

@hxsf looks awesome! Yeah, I forgot about additional capacity for underscores %)

@hxsf: That looks great! Do you mind adding a license to your gist?

@adombeck add MIT license.

@hxsf: Great, thanks a lot!

@elvizlai I update the code. and it works

good guys ! keep it up!
kebab case should be concluded here as well

@abdennour just replace '_' with '-' in the code, and change the function name. I think it will work.
