Hi everyone! I recently build an interesting Go tool - GPM (Go Project Manager). It allows you to build and manage go projects. Ont op, it also allows to update version of Go from cli. Check it out: https://github.com/YashishDua/gpm Feedback is appreciated! -- You received this message becaus

@Ian, I have been thinking and I’ve come up with a possible solution to yours and some other problems. I’d love to hear your thoughts on it. Note, that this is a very fresh idea. I’m addressing two problems here: 1. Inability to do Min/Max and other generic numeric functions. 2. The

Re: [go-nuts] Go 2 generics counterproposal: giving up restricting types

Hello, I'm not sure that Min and Max need to be in the 80%. It's annoying to write them repeatedly, but they are also very short. The place where I typically miss generics is larger chunks of code, such as concurrency patterns. I'm certain others are looking at datatypes. Why do Min and Max

Re: [go-nuts] Go 2 generics counterproposal: giving up restricting types

Because Min and Max are very good and simple indicators of whether the mechanism is generic enough to handle a fairly common idiom: small functions for similarly behaved items, say comparable items, which are annoying and repetitive to write for every data type which might support the operation

[go-nuts] Re: Go Module Mirror and Checksum Database in Beta!

See https://go.googlesource.com/proposal/+/master/design/25530-sumdb.md The current behavior is not ideal from a security point of view. So it is good that 1.13 is fixing this. And unless the fix is default, most users will not get the benefit. Anyone who wants to old behavior just needs to set t

Re: [go-nuts] Go 2 generics counterproposal: giving up restricting types

Is that really true though? You can have one package that defines min/max for the built-in types (because it uses operators), and then one that uses method(s) Less() and Equals() that works with generics. A similar technique can be used in sorting. -Original Message- >From: David Ri

Re: [go-nuts] Announcing NSWrap -- a comprehensive Objective-C binding generator for MacOS

ARC support should be doable, it would mean at least i) using bridging casts instead of void* for every Objective-C object, and ii) disabling retain, release and autorelease methods, and disallow NSAutoreleasePool class. On Friday, May 31, 2019 at 11:51:01 AM UTC-4, Robert Engels wrote: > > Isn

Re: [go-nuts] Announcing NSWrap -- a comprehensive Objective-C binding generator for MacOS

Also I don't think an API is going to assume or require ARC -- as far as I understand it, ARC is just a compiler shortcut that adds retain and release calls so the programmer doesn't have to, it is not any sort of runtime memory management or garbage collection system. As long as Clang has a -f

Re: [go-nuts] Go 2 generics counterproposal: giving up restricting types

Btw, as is demonstrated in the proposal, sorting can be solved by passing a comparator to the function: ```go func Sort(a []gen T, less func(T, T) bool) ``` This is actually a far more flexible way than sorting based on an operator or a `Less` method. Sorting based on an operator or `Less` limits

This seems similar to previous proposals based on introducing kind-based type categories for contracts. Putting the kind right there in the arg instead of a separate contract seems like an improvement, keeping it more local to where it is used. Why not just take this one step further and just

I see. No, that is not how it works, the user needs to manually handle memory management for all Objective-C objects, calling Release() on objects that are manually allocated and no longer used, and calling Retain() to take ownership of objects that need to be kept. In many contexts (e.g. NSApp
