Thanks Robert, this is what I ended up doing. I wouldnt say it was trivial though :-) https://github.com/Velocidex/json Thanks and sorry for hijacking this thread. Maybe a suggestion - if users are not expected to change time.Local maybe it should be made private or at least wording in the module s

Re: [go-nuts] Does method with pointer receiver keeps track of the receiver instance

I have tried the following example: https://play.golang.org/p/OfeWQH5S-Ju ``` func main() { nextFunc := getNextFunc() fmt.Println(nextFunc()) // prints 1 fmt.Println(nextFunc()) // prints 2 runtime.GC() fmt.Println(nextFunc()) // prints 3 fmt.Println(nextFunc()) // prints 4 } ``` It appears that

[go-nuts] Does method with pointer receiver keeps track of the receiver instance

Hi Go community, I am wondering if a method with the pointer receiver keeps the receiver instance from garbage collected. To put the idea into a code example ``` type counter struct { c int } func (c *counter) next() int { c.c = c.c + 1 return c.c } func getNextFunc() func () int { // Questio

Little old, but this might also help. A while back I built a helper package to deal with these issues for canvas rendering from Go. https://github.com/markfarnan/go-canvas I'm currently working on it to add WebGL support & get it working in TinyGo (some issues still). Regards Mark.

Re: [go-nuts] When set time.Location, will be detected Data Race

Yea, it is strange the the Json encoder api doesn’t allow the caller to provide a mashaller for any type. It would be trivial to change the code to do so. That being said I’m sure you can find custom json libs on the web that will do this. Or fork it yourself - it is not a lot of code. > On J

Re: [go-nuts] When set time.Location, will be detected Data Race

To be clear, the time.MarshalJSON() function produces valid RFC 3339 timestamps which allow arbitrary timezones. This means that local time offset is used in the string representation. Although all representations are technically equivalent their string form is not so we need to do special parsing
