Hi! I've created the Bird - https://github.com/melezhik/bird - Linux servers verification tool written on Raku ( former Perl6 ) and with Raku API. With recent changes with Opscode Chef and also if you want a programmatic API ( not YAML coding like in Goss ) you might want to take a look at the Bird. The project is still in alpha,but I am open for suggestions.
I've dropped an asccinema if someone wants to see a real example of work - <a href="https://asciinema.org/a/428954" rel="nofollow">https://asciinema.org/a/428954</a>
current API is documented here - <a href="https://github.com/melezhik/bird/blob/master/documentation/dsl.md" rel="nofollow">https://github.com/melezhik/bird/blob/master/documentation/d...</a>
