# Golang IoC
This is a pure golang library to using inversion of control (ioc) in golang
## Installation
```bash
go get github.com/morilog/gioc
```
## Example
```golang
package main
import "guthub.com/morilog/gioc"
import "log"
import "fmt"
func main() {
// Bind binds a resolver to abstract type and
// the resolver called every time you needed to the type
gioc.Bind(func () (Greeter, err) {
return &GoodMorning{}
})
var g Greeter
if err := gioc.Make(&g); err != nil {
log.Fatal(err)
}
fmt.Println(g.SayHello()) // prints "good morning"
gioc.Singleton(func (greeter Greeter, c *SimpleClient) (Mailer, error)) {
return &simpleMailer(simpleClient: c, g: greeter), nil
}
var m Mailer
if err := gioc.Make(&m); err != nil {
log.Fatal(err)
}
m.Send("[email protected]", "don't reply me")
}
type Greeter interface{
SayHello() string
}
type Morning struct{}
func (g Morning) SayHello() string {
return "good morning"
}
type Mailer interface {
Send(to string, msg string) error
}
type SimpleMailer struct{
g Greeter
simpleClient *client
}
func (s *SimpleMailer) Send(to string, msg string) error {
msg = s.g.SayHello() + msg
s.simpleClient.SendText(to, msg, "[email protected]")
}
```
