Thanks for the PR, but I think this change is too specific to this one problem. I think what I'd prefer, if you're willing to iterate, would be a new field OrigHelp which is just the original un-interpolated help string, and make the interpolateHasVar() function public for reuse as HasInterpolatedVar(). This will be general purpose enough so that the fields can be reused in the future for different purposes, while still fixing this issue.

Sounds good.

One quick question, does interpolation allow me to obtain string like ${env} after interpolation? I think $${env} should be interpolated into ${env}, yes?

Kong doesn't currently support escaping $, which is a bit of an issue, so I think that $$ could/should be the escaping system, yeah.

I see. Because reading README makes me think that it supports escaping, given that it is written Kong will append ($$${env}) to the help string. I will open an issue to track this.

Made: #248

Updated it as requested.

Thanks!

Superb!

Care to make a release with those recent fixes?

And, BTW, I really love this package. It is really smooth. Thank you for it!
