Plugins use of Go 1.8

This is a creation in Article, where the information may have evolved or changed.

Go 1.8 provides us with a new tool for creating a shared library called plugins! Let's create and use a plugin. The current plugin only works on Linux and Darwin.

Install 1.8BETA1, do not make instructions.

Create a plug-in method to Aplugin.go:

package mainfunc Add(x, y int) int {    return x+y}func Subtract(x, y int) int {    return x-y}

Then build the plugin:

Run the following command to build the plugin:

go build -buildmode=plugin

Build the specified file plugin aplugin.go to aplugin.so:

go build -buildmode=plugin -o aplugin.so aplugin.go

Loading plugins:

p, _ := plugin.Open("./aplugin.so")//p, err := plugin.Open("./aplugin.so")

Call Plugin:

add, _ := p.Lookup("Add")sub, _ := p.Lookup("Subtract")

Using plugins:

sum := add.(func(int, int) int)(11, 2)fmt.Println(sum)subt := sub.(func(int, int) int)(11, 2)fmt.Println(subt)
