This works great, thank you! And with minimal changes to my existing code (that's why I didn't like so much the other proposals that use time.After or time.Timer, but thanks anyway!). Am Mittwoch, 31. August 2016 16:06:58 UTC+2 schrieb Marvin Renich: > > > Does this do what you want? > >

[go-nuts] `go test -i` considered helpful?

I was running tests against a new project, and it was really slow. When I ran with -x I saw a bunch of build steps that didn't seem to be necessary. Spelunking through docs, reveals that `go test` doesn't install artifacts. `go test -i` does install artifacts but doesn't run the tests. So I

Re: [go-nuts] on GOPATH

For projects that are mostly not go (or go is a component anyway) you could do $HOME/project/src/ and then point $GOPATH=$HOME/project. You can use 2 different segments in $GOPATH (GOPATH=/foo/bar:/bar/foo) and go get will place go gettable packages in the first segment of $GOPATH. On Thu, Sep 1,

Re: [go-nuts] why this code deadlocks?

I think you can still deadlock, but I'm not sure if the `default:` case is considered for random selection of a select like other branches are. It would just be less deterministic. On Thu, Sep 1, 2016 at 10:38 AM Darren Hoo wrote: > Got it, using buffered channel works for

[go-nuts] on GOPATH

hello gophers, How people do use GOPATH? having a single workspace for all my projects doesn't really work for me. Some project might involve more than a go portion and really shoehorning them into a go tree doesn't sound right. I'm completely fine with switching GOPATH every time I switch

Re: [go-nuts] `go test -i` considered helpful?

What's weird to me is that go test -i doesn't actually run tests. Maybe go test -I which does both? On Sep 1, 2016 11:41 AM, "Ian Lance Taylor" wrote: > On Thu, Sep 1, 2016 at 11:24 AM, 'Tim Hockin' via golang-nuts > wrote: > > I was running

[go-nuts] Delve within Vim 8 or neovim?

Has any experimented with using delve within either vim 8 or neovim (both of which I believe have better async support for debuggers)? Delve works well under GUD mode in emacs with Evil vim emulation but it would be nice to use it directly. -- 4096R/EA75174B Steve Mynott

Re: [go-nuts] on GOPATH

Hi Maurizio, I tend to use go vendoring for this purpose. I set GOPATH to $HOME, and this is my "global" environment. Each project is checked out to its module path. Instead of using 'go get' to get dependencies, I use git submodules via vendetta. This checks out all of the dependencies for

Can it work when the forked gh repo contains many packages that sometimes use each other? It feels weird to be masking the very repo I cloned to work in... Now I am using the approach outlined by Francesc Campoy in http://blog.campoy.cat/2014/03/github-and-go-forking-pull-requests-and.html Neat

fmt.Sprint(sl) is not the same as fmt.Sprint(*sl). That makes the String methods in both examples different. On Thursday, September 1, 2016 at 12:02:04 PM UTC+2, Shulhan wrote: > > On Thursday, 1 September 2016 16:25:24 UTC+7, dja...@gmail.com wrote: >> >> Hi, >> Do you know what infinite
