Re: [go-nuts] Golang text template - time.Format epoch

Thanks Marvin! that's exactly what i need bwt, is there any way to get current timestamp inside the template (without referencing to the data structure) ? something like that: "timestamp: {{time.Now.Unix}}" On Wednesday, December 7, 2016 at 5:47:36 PM UTC+3, Marvin Renich wrote: > > * skrutsko

[go-nuts] Idiomatic way of handling http requests in separate goroutines

Hi gophers, I'm designing a service exposed through a http server which uses a pool of workers to process requests. At the moment my handlerFunc look similar to this: func aHandler(w http.ResponseWriter, r *http.Request) { var wg sync.WaitGroup wg.Add(1) reqQueue <- &Reque

[go-nuts] Re: Struct Compatibility in unix.Syscall

You can use go tool cgo -godefs *file*.go to generate the Go structs from C structs and either use them as-is or get an idea how you should pad your hand-written Go structs. file.go will have to do an import of the right .h file(s), something like: /* #include "file.h" */ import "C" ... On Tuesd

Docker add, or whatever is pushing files into your container is probably not respecting timestamps so the .a files are older with respect to .go files (pkg sorts above src) Why do you want to build inside a container, is that just adding an extra level of indirection to what is a simple process

What's the best practice around handling embedded interfaces that are nil? For example: https://play.golang.org/p/EcqV7h9cNU Is there a better way than wrapping the embedded interface's methods and forwarding down as long as it's not nil? I guess another approach would be to create a NoOpEven
