04:23:00veganskmcc, is it your issue? https://github.com/nim-lang/Nim/issues/4631.
04:23:56mcci was the one who filed that issue but this is a different issue
04:24:03mccthat's about deep copies. right now i'm just trying to make a shallow copy.
04:24:56veganskmaybe you can try workaround with JSON.parse(JSON.stringify)?
04:30:23mcci mean, right now i'm just trying to copy an array.
04:30:38mccand i'm confused about when assigning an array assigns a reference to the array and when it assigns a copy of the array.

08:26:51flyxwhat's the state of making `not nil` the default? I am currently trying to use some `not nil` and it has quite big issues: https://github.com/nim-lang/Nim/issues/4686
08:32:35ArrrrI think this is the last thing said on the subject https://github.com/nim-lang/Nim/pull/2064#issuecomment-74165750
08:33:32flyxArrrr: not quite. it is mentioned as goal of the BountySource fundraiser.

09:01:07flyxwhat I wanted to say is that these errors look like parser errors that will also apply if `not nil` is made default and `or nil` is the new "nillable" attribute. then you suddenly have problems of declaring nillable types.

15:25:38GustavoLapastaGiven a string and its length as an int32, how do I append the 4 bytes of the int32 at the start of the string?
15:26:18GustavoLapastaI use it for a trivial tcp "protocol", first I send 4 bytes for the payload length, then the payload.
15:26:48GustavoLapastaI know how to do it in c with some bytemasks, but how to do it in nim?

15:36:19euantorGustavoLapasta: This seems to work: https://glot.io/snippets/ei0hmynus0
15:37:32euantorThough if you need to make sure the endianness is correct, you should use shifts as you would in C
15:38:59*brson joined #nim
15:39:27GustavoLapastaeuantor that's great, although I don't understand this line:
15:39:28GustavoLapastalet casted = cast[array[0..3, uint8]](someInt)
15:40:03euantorIt's casting the integer to an array of 4 elements of type 8 bit unsigned integer (byte)
15:40:12GustavoLapastaand it's legit?
15:40:22euantorYup. Run it in the link
15:40:25euantorNim is clever :)
15:40:39GustavoLapastafascinating. Thank you euantor
15:40:53euantorMight not be the recommended way, but it seems to work

20:47:41federico3dom96: getting some serious funding from a company could be the next goal
20:49:21dom96sure, question is: how can a company benefit from funding a programming language like Nim?
20:49:50kierEmbedded?
20:50:35federico3indeed, embedded/microcontrollers, phones, but also microservices
20:50:43kierMaybe there's a market for Nim in programming microprocessors for IoT devices
20:50:50kierYea
20:52:47federico3the benefit of using the same language on micros, servers and even the JS UI is compelling
20:56:49gokrI made a first shot at that btw, Ardunimo :)
20:56:58gokrIt's on github
20:58:09gokrThe idea was simple - use c2nim to wrap the Arduino libs and drive the compilation via a Makefile since several parts of the tool chain needs to be controlled.
