Re: [go-nuts] import a file

Hola! Based on your initial project layout you have a couple of issues. When using the legacy gopath everything should ideally live under that path. Imports then become relative to that root. Your main lives outside of the root which works with go run but is not how a project should be structured

[go-nuts] [ANN] GoLand 2020.2

Hi Gophers, I'm here with a small update about our latest release of GoLand, the Go IDE from JetBrains. In this release we worked to: - improve the Go modules support - navigate from comments to symbols definitions - add a Problems View window - add a few new inspections for things like string(i

Re: [go-nuts] import a file

Thanks Jesper and Volker. After reading the article(s) and go help modules and a few blogs, I still was not able to see why deleting go.mod makes the program import jsonstuff package, and compile and run? Modules are a great idea and I want to use them, but I can't get it to compile a "hello golang

I have a library that is used by cross platform binaries running in corp. Some of these binaries don't necessary run google.Init. My library is using base/go/log package but this doesn't work when google.Init isn't called. It prints to stderr with a message "ERROR: logging before google.Init".

Re: [go-nuts] Error Handling in Go 2

In that proposal, some more syntax and semantics are being added - IMHO. One problem here is the name of the error variable. Here we explicitly have to used named return values - no new syntax there. And return() and panic() on left side, only accept error type. They will only be triggered when

Sure, I now have this as a drop-in replacement for json.Unmarshal: func StrictUnmarshal(data []byte, v interface{}) error { dec := json.NewDecoder(bytes.NewReader(data)) dec.DisallowUnknownFields() return dec.Decode(v) } I just wondered if I was missing something. -- You received this message b

Re: [go-nuts] builtin function definitions

The good news is that Go is simpler than many other languages, with fewer constructs, concepts and corner cases. So after using it for a while, you will rarely bump into anything "new". Reading the language spec is great, and I have done it myself a couple of times. But, depending on your level

Re: [go-nuts] import a file

The best advice is: Read How to Write Go Code https://golang.org/doc/code.html and stick to it. Yes, modules are the thing to be used 1. But naming a module "src" is begging for trouble. Name your module either something like julesgocode.org/firsttry or maybe github.com//firsttry 2. If your
