# pubsub-go
Simple pub/sub library written in Golang.
[](https://godoc.org/github.com/ryskiwt/pubsub-go)
[](https://github.com/ryskiwt/pubsub-go/blob/master/LICENSE)
### features
- quite simple interface (Pub/Sub/PSub)
- type of topic is string
- type of message is interface{}
- support pattern subscribe (PSub/PUnsub)
### interface
```go
type Hub interface {
Pub(topic string, msg interface{})
Sub(topic string) <-chan interface{}
Unsub(topic string, ch <-chan interface{})
PSub(pattern string) <-chan interface{}
PUnsub(pattern string, ch <-chan interface{})
Close()
Context() context.Context
}
```
### example
```go
package main
import (
"fmt"
"time"
pubsub "github.com/ryskiwt/pubsub-go"
)
func main() {
h := pubsub.NewHub(32)
subChan11 := h.Sub("/some/topic/1")
go func() {
for msg := range subChan11 {
fmt.Printf("subChan11, TOPIC: /some/topic/1, MSG: %s\n", msg)
}
}()
subChan12 := h.Sub("/some/topic/1")
go func() {
for msg := range subChan12 {
fmt.Printf("subChan12, TOPIC: /some/topic/1, MSG: %s\n", msg)
}
}()
subChan2 := h.Sub("/some/topic/2")
go func() {
for msg := range subChan2 {
fmt.Printf("subChan2, TOPIC: /some/topic/2, MSG: %s\n", msg)
}
}()
subChan3 := h.PSub("/some/topic/*")
go func() {
for msg := range subChan3 {
fmt.Printf("subChan3, TOPIC: /some/topic/*, MSG: %s\n", msg)
}
}()
h.Pub("/some/topic/1", "message 1 !")
h.Pub("/some/topic/2", "message 2 !")
h.Pub("/some/topic/3", "message 3 !")
h.Pub("/some/topic/1", "message 4 !")
h.Pub("/some/topic/2", "message 5 !")
h.Pub("/some/topic/3", "message 6 !")
<-time.After(time.Second)
h.Unsub("/some_topic/1", subChan11)
h.Unsub("/some_topic/1", subChan12)
h.Unsub("/some_topic/2", subChan2)
h.PUnsub("/some_topic/*", subChan3)
}
```
```sh
$ cd example
$ go run main.go
subChan11, TOPIC: /some/topic/1, MSG: message 1 !
subChan12, TOPIC: /some/topic/1, MSG: message 1 !
subChan12, TOPIC: /some/topic/1, MSG: message 4 !
subChan3, TOPIC: /some/topic/*, MSG: message 1 !
subChan3, TOPIC: /some/topic/*, MSG: message 2 !
subChan3, TOPIC: /some/topic/*, MSG: message 4 !
subChan3, TOPIC: /some/topic/*, MSG: message 5 !
subChan11, TOPIC: /some/topic/1, MSG: message 4 !
subChan2, TOPIC: /some/topic/2, MSG: message 2 !
subChan2, TOPIC: /some/topic/2, MSG: message 5 !
