[go-nuts] Re: Redfining loop variable semantics - what's the plan?

Not to mention that the change for "for;;" is so counter-intuitive and violates the try-to-be-explicit principle in Go. On Wednesday, April 12, 2023 at 9:08:24 AM UTC+8 tapi...@gmail.com wrote: > The plan for “for;;” is much more risky than “for-each”, because “for;;” > has more variation uses

[go-nuts] Re: Redfining loop variable semantics - what's the plan?

The plan for “for;;” is much more risky than “for-each”, because “for;;” has more variation uses in reality. I have no doubt that many non-bug compatibility-broken or performance-degradation cases will be found in the GOEXPERIMENT phase. On Saturday, March 25, 2023 at 2:44:59 PM UTC+8 Amnon

Re: [go-nuts] Map of Types is impossible, is there any alternative solution?

I had written out a message to suggest this approach but deleted it because it still required a type switch afterwards. Later I realized that the variant types of the message could easily be handled by an interface, like this: type Message interface { Build([]byte) Message Handle() error }

Re: [go-nuts] Map of Types is impossible, is there any alternative solution?

You can do: var messageProcessors = map[uint8]func([]byte) Message { 0: processorForType0, 1: processorForType1, ... } Then: output:=messageProcessors[id](payload) Of course, with the appropriate error checks. On Tue, Apr 11, 2023 at 3:13 PM Bèrto ëd Sèra wrote: > I do know there's no

[go-nuts] Map of Types is impossible, is there any alternative solution?

I do know there's no way to use var rule = map[uint8]Message{ 0: thisType, 1: thatType, 4: someOtherType, . } type Message interface { Become(data []byte) } type thisType struct { data []byte } func (my *thisType) Become(data []byte) { } type thatType struct {

[go-nuts] Map of types?

Good evening, I do know there's no way to use var rule = map[uint8]interface{ 0: thisType, 1: thatType, 4: someOtherType, . } type Message interface { Become(data []byte) } type thisType struct { data []byte } func (my *thisType) Become(data []byte) { } type

[go-nuts] Re: [Contribution] Go_Updater shellscripting (GNU/Linux or WSL)

Something to consider: if you untar over an existing installation, then it's possible you will be left with stale artefacts - e.g. source files that were in an old version that aren't in the new one. I've been bitten by this in other projects. I haven't been bitten by this in Go, but I always

Re: [go-nuts] Is there a golang download for latest patch release like 1.20.x?

[Aside: I think it would have been better to start a new thread rather than hijack an unrelated conversation] go.dev and pkg.go.dev both work perfectly for me. Are you able to resolve those names to IP addresses - if so, what? What do you see when you attempt to connect? Do you have a static

[go-nuts] [Contribution] Go_Updater shellscripting (GNU/Linux or WSL)

hello, i did this Bash Script (only Linux/WSL) to update GoLang, it will give you some options, like update to the next patch (1.20.x) or the next minor version (1.21) only stable ones (not beta neither rc), if someone found useful, here is the link:

Re: [go-nuts] Redfining loop variable semantics - what's the plan?

FTR I have been using Go for 10 years and I certainly *have* read the spec - a lot, as you're well aware. I still occasionally make this mistake. Being able to explain *why* code is buggy doesn't prevent me from introducing a specific bug. On Tue, Apr 11, 2023, 10:54 Axel Wagner wrote: > > > On
