Package plugin allows you to easily define a plugin for your Go application and have it call out at runtime, to C shared libraries fully or partially implementing the user-defined plugin.
The advantage of this is that the implementation of the plugin is language-agnostic.
Tested only on 64bit Linux.
Go 1.5+ is needed
go get -u github.com/tiborvass/go-plugin
package main
import "github.com/tiborvass/go-plugin"
type MyPlugin struct {
plugin.Plugin
Hello func()
Goodbye func()
}
func main() {
var p MyPlugin
if err := plugin.Open(&p, "path/to/shared/lib/plugin"); err != nil {
panic(err)
}
defer p.Close()
p.Hello()
p.Goodbye()
}You'll need gcc installed for this example to work.
$ cd $GOPATH/src/github.com/tiborvass/go-plugin
$ make clean
$ make
go build -buildmode=c-shared -o plugin-go/plugin.so ./plugin-go
gcc -fPIC -shared -o plugin-c/plugin.so ./plugin-c/plugin.c
go test
Hello from main
Hello from Go plugin
This is a function implemented only in Go
Hello from C plugin!
