16:33 <henk> hm, I’m a bit confused … I want to define an object `DnsChallenge` in my code. this is supposed to contain, among other things, an object Acme::Client::Resources::Challenges::DNS01. but I also want to have an array of all `dns_challenges`. so AFAIU I need to use references to these objects, not just assign them because that would copy them. I’m trying to find more info about this but fail to

16:33 <henk> find a straightforward answer. any advice what to read? or which keywords to search for? or just straight up examples how I need to do this in the code?

16:39 <sam113101> they are not really being copied by default, check that:

16:39 <sam113101> >> a = 'test'; b = a; b << 'yo'; a

16:39 <ruby[bot]> sam113101: # => (https://carc.in/#/r/gi52)

16:40 <sam113101> what

16:40 <sam113101> >> a = 'test'; b = a; b << 'yo'; p a

16:40 <ruby[bot]> sam113101: # => "testyo" ...check link for more (https://carc.in/#/r/gi53)

16:42 <sam113101> does that help henk?

17:07 <henk> hm, that seems like I’m worrying too much about it …

17:07 <henk> sam113101: yes, thank you

19:11 <[0x1eef_]> henk: Yeah Ruby is not like C or C++ in that regard. Assignment does not copy. It references the same object.

19:16 <johnjaye> apparently in c++ the statement "a = b" can mean anything because of operator overloading

19:17 <johnjaye> hence you can never understand the code fully because anything could mean anything

19:30 <[0x1eef_]> xD

20:33 <henk> I see, thanks

23:03 <PaulePanter> Hi. Can you give a suggestion how to avoid having RPATH set in a library?

23:03 <PaulePanter> Issue is https://github.com/sparklemotion/nokogiri/issues/3133

23:04 <PaulePanter> You experts often have a good idea saving ignorants like myself a ton of time.

23:04 <PaulePanter> Thank you in advance.
