darkfish documentation warning output when installing gem

[Bartuz]

I just downloaded ruby 2.3 on my new system and installed dependencies on my project via: rvm use ruby-2.3.0 && cd rails/ && gem install bundle && bundle

I saw this output when parsing your documentation (this happened only to your gem)

I had the same thing today (rbenv ruby 2.4.1) when did gem update:

@ozgg Can you reproduce with rdoc --verbose to identify where the warning is arising? This output isn't enough to go on.

[ozgg]

@jeremy I'm not sure if I did everything right, but here is gist of output for rdoc --verbose which I ran in ~/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/mail-2.6.5

[jeremy]

Hmm no warnings there. Not sure what is tickling it, then!

[ozgg]

@jeremy maybe there is something to do with combination of rdoc, darkfish and mail? Anyway I don't think that's something critical :)

[ozgg]

I think it's only the problem of darkfish documenter, because there are pretty much similar warnings having darkfish with eval for other gems in Google.

Looks like this is fixed by https://github.com/rdoc/rdoc/pull/440
