Documentation for "container/heap" says Package heap provides heap operations for any type that implements heap.Interface. heap.Interface is type Interface interface { sort.Interface Push(x interface{}) // add x as element Len() Pop() interface{} // remove and return element Len(

I've tried this which you offered, I don't think that it is correct for the box. Besides, I have no idea why "H" disappeared with Linux executable? However, I think I'll try to use this for my tasks. Thanks for your information! Max Jason E. Aten於 2020年4月10日星期五 UTC

[go-nuts] Re: Is it possible to segment CMD window on Windows and segment Terminal window on Linux with golang?

I think that you are right. I found that the "Hello World" executables are a little different. In fact, the executables are compiled from the same source code, which means that it might cause a lot of problems if I use it. I'll try to create a web browser. Thanks for your suggestions! Max Jason E

Re: [go-nuts] testing code that uses ioutil.ReadDir?

I am the author of the test coverage tool, and I do not believe that 100% code coverage is the right goal. Coverage is a proxy for testing quality, but not a guarantee of it. Getting to 100% coverage is a better indicator of chasing metrics than of actually writing good tests. I'm happy if my cover

Go is a simple language. Code in Go does what it says. No magic. That is its beauty. That is its power. On Sunday, 12 April 2020 03:59:08 UTC+1, Tanmay Das wrote: > > Say you have a struct Foo and you access fields and call methods on it as > you normally would. But is it possible to execute

Re: [go-nuts] Intercepting field access and method call

You probably want to use interfaces. You can do a lot of “seemingly dynamic” programming with interfaces. There are statically typed languages that pretty dynamic - Java with reflection and proxies - but Go is also statically compiled which makes the options limited - which is usually a good th

Re: [go-nuts] Intercepting field access and method call

Hi Jake, Thanks for the wishes. BTW, this is not my first statically typed language, I know a little bit of C and Java. I was under the impression that Go is capable of some dynamic behavior. Maybe things like Go's type inference, duck typing, empty interface{} led me to believe that. All these

Re: [go-nuts] Intercepting field access and method call

And just to add, since you mentioned fields on a struct: all fields are initialized to their "zero value" (which for example is 0 for an int, or empty string for a string). So there is no such thing as a non-existent or uninitialized field. -- You received this message because you are subscri

Re: [go-nuts] Intercepting field access and method call

It sounds like maybe this is your first statically typed language. Go is statically typed, which means that the scenarios you are talking about can not happen. That is by design, and has huge benefits for code reliability, and also readability. If you call a function that takes a Foo struct as a

[go-nuts] testing code that uses ioutil.ReadDir?

Is there a particular reason you want 100% code coverage? Not trying to start a flame war: given limited time and effort, unless the rest of my projects had 100% coverage already, I would personally spend my time working with a package with lower coverage, or just fixing known bugs. If your cod
