Support go module

[zliang-min]

Expecte when run yaegi in a folder that contains go.mod, one can use import to import the packages defined in the module in go.mod. Currently when I do that, it will report unable to find source related to: "github.com/Gimi/my-module/pkg".

Hello, yes for now the only way to manage dependencies is to use the vendor directory.

Can you expand on how to manage dependencies?

Let's say I have a local package on my system that I want to import, how do I achieve that?

[ldez]

Something like that:

package main

import (
	"go/build"

	"github.com/containous/yaegi/interp"
	"github.com/containous/yaegi/stdlib"
)

func main() {
	// Create an interpreter and setup a GOPATH
	i := interp.New(interp.Options{GoPath: build.Default.GOPATH})
	// import stdlib
	i.Use(stdlib.Symbols)

	if _, err := i.Eval(`import "github.com/foo/bar"`); err != nil {
		b.Fatal(err)
	}

	fnHello, err := i.Eval(`bar.Hello`)
	if err != nil {
		b.Fatal(err)
	}
  
	// ...
}

$GOPATH/github.com/foo/bar/bar.go

package bar

import github.com/foo/boo

func Hello(){
  boo.Hi()
}

$GOPATH/github.com/foo//bar/vendor/github.com/foo/boo/boo.go

package bar

import fmt

func Hello(){
  fmt.Println("Hello")
}

or you can use the old GOPATH way (no vendor folder)

any news on this? because right now it is not working.
Even by pointing the interpreter to the right go env GOMODCACHE
