Disclaimer: this is not a direct answer to your question but rather an attempt to direct you to a proper way of solving your problem. Try to avoid a singleton pattern for you MyApp. In addition, New is misleading, it doesn’t actually create a new object every time. Instead you could be creating a new … Read more
The answer is you cannot replace the window procedure cross-process with SetWindowLongPtr and SetClassLongPtr . Calling SetWindowLongPtr with the GWLP_WNDPROC index creates a subclass of the window class used to create the window. An application can subclass a system class, but should not subclass a window class created by another process. Calling SetClassLongPtr with the … Read more

Below is a simple server that should get you started toward your goal. A couple of things to note about the implementation: The file names are loaded only once during program startup. If a file disappears while the program is running, the server will return a 404 when it comes up in the rotation. We … Read more
What I was trying to accomplish will be possible in Go v1.18, as commented by @torek in my question. For now, what I ended doing was this: handler := &ws.SessionHandler{ Subscribers: make(map[chan json.RawMessage]bool), } I stopped relying on a go struct and communicated json.RawMessage in my channels. It’s not totally clean because I need to … Read more
I’m not sure what’s the essense of the question. IP_TRANSPARENT is specific to Linux (an OS kernel), so any code which makes use of it must run on Linux. Debugging (a running process) also must happen on Linux—for, I hope, reasons now obvious. But that does not affect building: when building on Linux, that should … Read more
go install installs a binary to $GOPATH/bin which is likely does not present in PATH env variable of your OS. You need to add$GOPATH/bin to your PATH: export PATH=$GOPATH/bin:$PATH solved go install but unable to run app from folders uther than bin
To initialize an anonymous struct, you have to declare the type. You declared the root anonymous struct, but you need to do again for each nested anonymous struct: func wrapHal(selfHref string) interface{} { return struct { _links struct { self struct { href string } } }{ _links: struct { self struct { href string … Read more
The reason you see: %!(EXTRA uint8=10) is you are calling Printf without a format option. You should just call fmt.Println instead. 10 is the encoding of the newline character. Now, the meat of your question: You have a byte array (slice). You are trying to interpret it as lines (strings separated by ‘\n’). Interpreting a … Read more
It’s in the spec. Having low or high equal to the length is allowed. For arrays or strings, the indices are in range if 0 <= low <= high <= len(a), otherwise they are out of range. As to “why is this not an error”: you can visualize the slicing operation as cutting between the … Read more
You can’t kill a goroutine from outside – you can’t even reference a specific goroutine; nor can you abort a blocking operation. You can, however, move the for to the outside: go func() { for { select { case close := <-closeChan: return 0 case i,ok := <-c: // do stuff if !ok { // … Read more
This doesn’t do anything at runtime, but unless the *selectQuery type satisfies the interface QueryAppender, compilation will fail. It’s a kind of static assertion. 0 solved Confused about go syntax [duplicate]
Go is lexically scoped using blocks. In this example: list := []string{“a”, “b”, “c”} for { list := repeat(list) The second list shadows the first within the for block, and doesn’t alter the outer list variable. Because the arguments to repeat are evaluated before the inner list is declared and assigned, repeat receives the value … Read more
Just return the interface, it allows you to return nil: func FindStuff() Stuff { return nil } Working example solved What’s the idiomatic way in go to return optional interface values?
I’ve read also that people where going to import everything from “GitHub.com”, but it makes no sense for me to first push my code to GitHub before I can test it in my local project. You don’t have to push it anywhere before you can test it. You only have to choose what your import … Read more
