Re: [go-nuts] How to conv [3]int to []int ?

That's not necessary. https://play.golang.org/p/_iHnithuxz What a[:] does is create a slice header with the address pointing to the zeroth element of a. The code that is generated is exactly the same for both (you can check this with go tool compile -S). On Thu, 2016-11-10 at 23:46 -0800, steve

I haven't thought too much about it but there is possibly an alternative logic by having the wrappers add a Wrap() http.ResponseWriter that would return the wrappee. So first, one would test for that Wrapper interface, then return the wrappee if the test turns out to be positive. Then one could

[go-nuts] FPDF question (jung-kurt)

Hi, when I use AddFont I need a font specification in JSON format. But I really have no idea what should go in such a JSON file. I had this: pdf.AddFont("Ravie", "B", "c:\\windows\\fonts\\RAVIE.TTF") which is obviously wrong, since it only points to the font location in Windows. Any help ap

Re: [go-nuts] Re: [ANN] httpsnoop, an easy way to capture http related metrics (response time, bytes written, and http status code)

The goal is to check whether a http.ResponseWriter is a wrapper around another http.ResponseWriter. If so, we can check what the wrappee implements besides ServeHTTP(...). Maybe it is itself a wrapper. Maybe it is a Hijacker or ReadCloser... If this wrappee is itself a wrapper, the logic is rec

[go-nuts] time.Truncate output is _slightly_ different than expected

Here's a test case to show what I mean: func TestWat(t *T) { now := time.Now() trunc := rand.Int63n(int64(time.Second)) t.Logf("trunc: %v", trunc) t1 := now.Truncate(time.Duration(trunc)) t2 := time.Unix(0, trunc*(now.UnixNano()/trunc)) // this fails for some reason assert.Equal(t, t1, t2) } Fo

[go-nuts] Re: Concurrency and order of execution

Okay, that makes sense. I've updated my solution so that in the case that the channel only has a capacity of 1 the processing will be done without goroutines to ensure that it is done in serial. In the case that the channel capacity is larger then I don't care about how processing is ordered.

[go-nuts] Partial Variable Assignment

I thought it was possible to do partial assignment where, if one variable is already declared and a new one is not. https://stackoverflow.com/questions/39028645/golang-variable-assignment In the below example ok has been declared prior, but v has not. Trying to run the below results in an error

Re: [go-nuts] Partial Variable Assignment

I think what is happening when you do the := is that the ok in there is getting shadowed (the for loop is creating a new block) and so the compiler see it as a new variable that is not being used. Sent from my iPhone > On Nov 11, 2016, at 18:49, so.qu...@gmail.com wrote: > > > I thought i

No way, it only works in the same block : https://golang.org/ref/spec#Short_variable_declarations the for statement creates a new block . Le samedi 12 novembre 2016 03:49:35 UTC+1, so.q...@gmail.com a écrit : > > > I thought it was possible to do partial assignment where, if one variable > is

Re: [go-nuts] time.Truncate output is _slightly_ different than expected

You are dividing the number of nanoseconds since the Unix epoch by some random number of nanoseconds and chopping off the remainder. But a time.Time internally is an interval since another, much earlier, reference time. The remainder in that division will be different. //jb > On 11 Nov 2016,
