Re: [go-nuts] Interface method return other interface?

Thank you all for your feedback and input. Shame on me that I didn't look hard enough through the stdlib for getting some examples, but thanks Axel for pointing that out. On Thu, Oct 10, 2019 at 3:11 AM Robert Engels wrote: > > Ugh. Every time I see that I cringe > > > On Oct 9, 2019, at

Re: [go-nuts] go module & local package

Thanks for the reply. It's been helpful. It appears that godoc does not work with go module? Somehow my godoc only documents those packages in my gopath. On Wednesday, October 9, 2019 at 1:07:06 PM UTC+7, Dimas Prawira wrote: > > Let me define this first modules are collections of packages. In

[go-nuts] Re: About package lxn/walk

Don't know about the lnx package. And I didn't check your code. But I can answer beginner's questions: 1. The plus sign means concatenation for strings. var s = "text" s += "\n" 2. fmt.Println prints to standard output, but fmt.Sprintln prints to a string. 3. Similar answer: Use

[go-nuts] Re: About package lxn/walk

Welcome Max, First a tip. It is easier for people to view your code samples if you post them in the playground . Even though this code will not run in the playground, due to the imports, its a nice way for people to quickly see what you are talking about. The code

[go-nuts] why not heap.Pop return nil while h.Len is 0?

src/container/heap/heap.go: ```go func Pop(h Interface) interface{} { n := h.Len() - 1 h.Swap(0, n) down(h, 0, n) return h.Pop() } ``` While the h is empty, also the h.Len() equals to 0,why not return nil in advance? In the current way, we have to do boundary check in implement of Swap,

Re: [go-nuts] why not heap.Pop return nil while h.Len is 0?

Note that other languages, such as Python, have the same behavior as Go for the reason mentioned by Ian. If you call Pop() on an empty interface/list/etc., and it returns a distinct value for that condition, you still have to check that the pop failed. It is better to require the caller to do the
