API获取模块名称

Question

Is there an API to get the module name of a project which uses go 1.11 module system?

so I need to get abc.com/a/m from the module definition module abc.com/a/m in go.mod file.

Answer 1

As of this writing, I am not aware of any exposed APIs for that. However, looking at go mod sources, there is a function that can be quite useful in Go mod source file

// ModulePath returns the module path from the gomod file text.
// If it cannot find a module path, it returns an empty string.
// It is tolerant of unrelated problems in the go.mod file.
func ModulePath(mod []byte) string {
    //...
}

func main() {

    src := `
module github.com/you/hello

require rsc.io/quote v1.5.2
`

    mod := ModulePath([]byte(src))
    fmt.Println(mod)

}

Which outputs github.com/you/hello
