Early adopters VGo

This is a creation in Article, where the information may have evolved or changed. > View Original text: [Blog.keyboardman.me] (https://blog.keyboardman.me/2018/02/23/early-adopters-versioned-go/) has been, There is not a good solution for go-dependent package versioning, there are currently two main ways to ' Import Versioning ' and ' Semantic Versioning '. * Import Versioning: ' gopkg.in ' website, in fact, is a change of GitHub version of the redirector, you can through the ' gopkg.in/yaml.v1 ' and ' gopkg.in/yaml.v2 ' The import way to point to the different commit versions of the GIT library * Semantic Versioning: A file format specification was developed to describe the exact source and version information (DEP, glide) of the code in the Management Vendor directory (2018-02-20) days before Russ The Cox Blog introduces his new tool ' VGo ' for Go, which is a replacement for the Go tool designed to handle the package version, vgo the versioned go abbreviation, meaning the version of Go. VGO is currently only running on go1.10, otherwise it will get ' vgo objabi:cannot find gomips ' error. Install VGo first. "' Bashgo get-u golang.org/x/vgo ', let's try it first, then [official example] (https://research.swtch.com/vgo-tour). "' Bashmkdir $GOPATH/src/hellocd $GOPATH/src/hellocurl-ss https://swtch.com/hello.go > Hello.go ' ' Let's see ' Hello.go ' The content. "' Gopackage Main//import" Github.com/you/hello "Import (" FMT "" Rsc.io/quote ") func main () {FMT. Println (quote. Hello ())} "where the '//import ' Github.com/you/hello ' comment is used to tell the VGO module what the ' Import path name ' should be, and the other packages using this module will be used as the import identifier. Create an empty Go.mod file to mark the root of this project, and then edit theTranslate it, please. ' Bashecho >go.modvgo build ' can see the build executable and modify the ' go.mod ' content, automatically generating dependencies. "Bashmodule" Github.com/you/hello "Require" rsc.io/quote "v1.5.2" ' Go.mod ' file contains the minimum version of the package that the module depends on. If the module does not provide a ' tag ' version. For unnamed commits, ' V0.0.0-yyyymmddhhmmss-commit ' represents a commit of a specified date. The ' go.mod ' file can also be used to implement the excluded and replaced versions, and the ' go.mod ' files need to be modified manually. "Bashexclude" Rsc.io/sampler "V1.99.99replace" rsc.io/quote "v1.5.2 =". /quote "" However, the most important change is to end the ' Gopath ' as the setting for the Go Code workspace, because the ' go.mod ' file contains the full module path and also defines each dependent version used, so it contains ' go.mod ' The directory of a file can be considered to be the root of a directory tree, which acts on its own workspace and is isolated from other similar directories.

I encountered some problems during the test, such as having a ' gopkg.in ' warehouse that uses tags instead of branches to mark major versions. The current VGO handles these warehouses with errors. "' Goimport (_" Gopkg.in/natefinch/lumberjack.v2 ") will get the following error.
