Re: [go-nuts] Can Generics match implementers of an interface?

Yes Ineed Mike! Generics can be good and can be bad... perhaps just as the OOP inheritance. And thanks Alex indeed! His answer was enlightening! TD;DR; Just another personal feeling. Prior to generics: with interfaces I live a happy life, I got all the generosity I shall need... if I wanna work

Re: [go-nuts] Can Generics match implementers of an interface?

Absolutely, some times generics are not needed. I actually don't find a need to use them that often which is probably why when I came across a use-case that really needed them I was so stumped as to how make it work. Kudos again to Axel for helping me recognize my blindspot. -Mike P.S. BTW,

Re: [go-nuts] Can Generics match implementers of an interface?

Yes, I was surprised too. It actually took me the better part of a day trying to get this to work before finally posting to the list. It turns out that this limit was actually documented by Ian Lance Taylor back in February 2023: https://github.com/golang/go/issues/58650 Look for the section

Re: [go-nuts] Can Generics match implementers of an interface?

Very interesting case. As Alex says, if you "help" the compiler writing the actual type parameter like `Append[Suiter](slice, suiter)` it works. I have seen this before in Java when generics comes into town... I guess with time golang team with time will improve the type inference engine... th

Re: [go-nuts] Re: custom slog Handler which adds Attribute and WithGroup

The slog API doesn't allow wrapping handlers this way. slog.Handlers hold state for the current open group. You'll need a full implementation of a handler to do this. (Technically it's possible if you record the group/attrs in With/WithGroup yourself and only call the wrapped handler in Handle, bu

[go-nuts] Can a lambda passed to other functions be inlined by a Go compiler?

Imagine you have something like this: * func foo(data []int, suitable func(v int) bool) []int { * * result := make([]int, 0, len(data) * *for _, v := range data { * *if suitable(v) { * *result = append(result, v) * *} * *} return result * *} * func main() {

Hi, I attempted to translate the linked JS implementation for fun. Maybe someone can use it as a starting point and correct or verify its correctness. https://go.dev/play/p/Wrw2yDRof0z Have fun! On 10/23/23 07:38, Jan wrote: hi, I did a quick search and I didn't find anything in Go. But loo

[go-nuts] Re: custom slog Handler which adds Attribute and WithGroup

As I got zero reply to that answer, let me rephrase it probably more easily: I would like to use slog, no other logging library I would like to have an entry called eventID which is at the root level and has a unique uuid for every log entry I would like to use a group for every application speci

[go-nuts] Go called by C: is the goroutine locked to a thread?

Hi, I'm writing a Go library to embed/extend CPython (Pygolo ). CPython uses thread local storage and therefore I need to care about pinning goroutines to OS threads accordingly. It's pretty much clear that when the Python interpreter is embedded it can be acces
