with this plugin it seems to generate wrong code :(

package main

import (
	"C"
	"fmt"
	"gitlab.com/IRSH/irshGoFramework/plugins/types"
)

// pluginName of the Web Plugin
const PluginName = "web"

type PluginStruct struct {
	types.DefaultPlugin
}

func (p PluginStruct) Greet() {
	fmt.Println("Hello Universe")
}

// Define Plugin (Web=false as it otherwise would create a dependency loop)
var Plugin = PluginStruct{
	DefaultPlugin: types.NewDefaultPlugin(PluginName, false),
}

The result code is

package main

        ret := new(WebPlugin)

        varPlugin, err := p.Lookup("Plugin")

        if typed, ok := varPlugin.(*main.PluginStruct); ok {
                ret.Plugin = *typed
        } else {
                return nil, fmt.Errorf("could not import variable 'Plugin', incompatible types 'main.PluginStruct' and '%s'", reflect.TypeOf(varPlugin))
        }

        return ret, nil
}

for some reason it tries to get PluginStruct from main but it needs to be more or less copied over.
