geektonilisitsyn: ping15:51
lisitsynhey15:51
lisitsynwhat's up15:51
geektonihi :) I was looking into the equals method of SGObject and I bumped into a problem :P15:52
geektoniThe idea was to convert it from this15:52
geektonivirtual bool equals(CSGObject* other, float64_t accuracy=0.0, bool tolerant=false);15:52
geektonito this virtual bool equals(const Some<CSGObject>& other, float64_t accuracy=0.0, bool tolerant=false);15:52
geektonibut, by doing this, we lose the polymorphism of the method. Which mean, I can't call equals on something like Some<CKNN>, even if CKNN is derived from SGObject.15:53
geektoniI thought that a possible way to fix this is by rewrite thing like this: https://pastebin.com/PmDc9gu915:54
geektonibut I don't like it very much15:54
geektonido you have some suggestion?15:54
geektoniapart from "let it be" ;)16:01
geektonithat could be still an option though16:01
lisitsynsorry distracted16:02
lisitsynoh that's pretty bad true16:02
lisitsyngeektoni: if we provide implicit Some(CSGObject*) it should work by default16:03
lisitsynI am missing something16:04
geektonimmh what?16:04
lisitsynokkkk prototyping16:05
lisitsyngive me a few mins16:05
geektonisure16:05

@iglesiasgmaybe we need to port that functionality from std::shared_ptr into Some16:09
-!- HeikoS [~heiko@89.105.104.229] has quit [Client Quit]16:10
@iglesiasglisitsyn, geektoni: should we just wrap std::shared_ptr with Some?16:12
geektonilisitsyn said he tried :P16:12
lisitsynhttps://ideone.com/pYlWBU16:13
lisitsynyeah you could try but it is no magic wand16:13
lisitsyngeektoni: check this ^16:13
@iglesiasglisitsyn: haha what is not magic wand?16:15
lisitsynstd::shared_ptr16:15
lisitsynwon't solve problems :)16:15
@iglesiasgit does this16:15
@iglesiasgwe can do polymorphism with it16:16
@iglesiasgI suppose internally it will essentially do something like that16:16
lisitsynyeah but it is not doing something magical you'd have to add it to Some16:16
@iglesiasgwith wrapping I was meaning doing something like16:16
@iglesiasgSome<T> = std::shared_ptr<T>16:17
lisitsynyes I started by inheritance16:17
lisitsynthe same thing16:17
lisitsyngeektoni: you may do another attempt ;)16:17
geektonilisitsyn: yeah sure ;) I got it anyhow. That's nicer!16:18
geektonilisitsyn: btw, I sent you a message on Saturday16:20
geektoniregarding Any.h16:20
lisitsynmissed it somehow16:20
lisitsynwhat's the q?16:20
geektoniI was trying to understand how any works, but I noticed that there are at least three different branches with different Any implementations.16:21
lisitsynoh16:22
lisitsyn:D16:22
geektoniOne has a now-owning policy, the others don't.16:22
lisitsynah16:22
lisitsynall non-owning policies are fcuked16:22
lisitsynsorry! :P16:22
lisitsynI failed miserably two times I guess16:22
geektoniahah ok16:22
geektoniBecause it is needed for the Tags, you said.16:23
lisitsynwell it is used by tags16:24
lisitsyngeektoni: well you have to drop the type16:24
lisitsynbut std::any is C++17 :(16:24
lisitsynit is in boost but it is too much16:24
geektonitoo far away I guess ;)16:24
lisitsynand it is deadly fcuked in boost sry!16:24
lisitsyn:D16:24
lisitsynit is soo bad in boost16:24
lisitsynrtti16:25
