[go-nuts] Re: get Package from types.Type

nevermind - I think I figured it out — just need to drill down Underlying until you find types.Named and get the Obj().Pkg() from that. Only Named types have a package home.. - Randy > On Feb 16, 2019, at 12:51 AM, Randall O'Reilly wrote: > > I’m probably missing something very basic, but I

Yeah, mmap is a valid solution. Of course, you end up with code that works less reliably on all platforms. And, depending on what kinds of operations you are doing you might not get a perf benefit. On Friday, 15 February 2019 19:34:55 UTC+2, Jeroen Massar wrote: > > Hi folks, > > Silly question

Re: [go-nuts] Re: get Package from types.Type

Underlying is the identity function for all types except *types.Named (https://github.com/golang/example/tree/master/gotypes#named-types), so this won't get you what you want. Instead what I think you're after is type asserting against the types.Type you have (https://github.com/golang/example/tre

Does anybody hear about implementations of dataflow visual design systems for golang? https://www.youtube.com/playlist?list=PLKYvTRORAnx6a9tETvF95o35mykuysuOw Now I'm playing with a serial port log processing, and totally disappointed with Node.js productivity even for such simple task as the

Re: [go-nuts] why go get does not work outside a module?

Well, the problem is that module aware go get will **still** download commands in GOBIN and **will** cache downloaded modules in GOPATH/pkg/mod. So I don't see a valid reason why it should not work outside a module. Thanks Manlio Perillo On Saturday, February 16, 2019 at 1:08:08 AM UTC+1, Tyler

The good news is that this is addressed for 1.12: #24250 cmd/go: allow "go get" when outside a module in module mode https://github.com/golang/go/issues/24250 It would be worthwhile to try the 1.12 release candidate if you can: https://groups.google.com/forum/#!topic/golang-announce/r0R2ji

[go-nuts] ctrl-c and Golang

I have the following program. The program is processing network packets at 1 Gbps rate. I don't want to print the rate for every packet. Instead, I'd like to save the rate in an array and dump the array on Ctrl-c of the program. When I dump the array on Ctrl-c, the data is all zeroes. Pleas

Re: [go-nuts] why go get does not work outside a module?

Thanks. The comment about tools dependencies was very interesting. Other package managers, like pipenv for Python, have the concept of dev dependencies. Basically, required packages are divided in two groups: packages and dev-packages: https://pipenv.readthedocs.io/en/latest/basics/#example-pip

Re: [go-nuts] ctrl-c and Golang

I suspect it's because your reference to the time_array is actually copying it into your closure that's running as the goroutine instead of making a reference to it. You might do better to pass that array as a parameter to the goroutine instead of trying to absorb it as context. I should note t

Re: [go-nuts] ctrl-c and Golang

Thanks, David. Let me look into passing as a parameter. Actually, I didn't paste all the code. My array in the for loop does have a check that if array limit is reached, I set the index to zero and overwrite data. Thus, the last 65536 entries are looked at. Hemant On Saturday, February 16,
