+# go-pluggable
+
+light Bus-event driven plugin library for Golang.
+
+`go-pluggable` implements the event/sub pattern to extend your Golang project with external binary plugins that can be written in any language.
+
+```golang
+import "github.com/mudler/go-pluggable"
+
+
+func main() {
+
+    var myEv pluggableEventType = "something.to.hook.on"
+    temp := "/usr/custom/bin"
+
+    m = pluggable.NewManager(
+        []pluggable.EventType{
+            myEv,
+        },
+    )
+        
+    // We have a file 'test-foo' in temp.
+    // 'test-foo' will receive our event payload in json
+    m.Autoload("test", temp)
+    m.Register()
+
+    // ...
+    m.Publish(myEv,  map[string]string{"foo": "bar"}) // test-foo, will receive our data as json payload
+}
+
+```
