README
A simple yet powerful dependency injection container for Go.
## Installation
```
go get -u github.com/pkg6/gdi
```
## Usage
Create a container
```
container := container.New()
```
## Set a value
```
container.Set("foo", "bar")
```
## Get a value
```
value,err:= container.Get("foo") // value is "bar"
```
## Check if a value exists
```
exists := container.Exists("foo") // exists is true
```
## Unset a value
```
container.Unset("foo")
```
## Register a service provider
```
type DemoServiceProvider struct {
}
func (d DemoServiceProvider) Register(container IContainer) {
container.Set("foo", "bar")
}
sp := &DemoServiceProvider{}
container.Register(sp)
```
## Register a Object
```
type Foo struct {
container IContainer
}
func (f *Foo) Construct(container IContainer) {
f.container = container
}
foo := &Foo{}
c.Set("foo", foo)
```
The service provider can then set values in the container
## Register a HandlerFunc
```
c.Handler(func(container IContainer) {
container.Set("handler", "handler")
})
```
The service provider can then set values in the container
## Panic handling
Methods like Get and Raw will panic if the identifier does not exist. You can recover from panics to handle the error in a graceful way:
```
defer func() {
if err := recover(); err != nil {
// handle error
}
}()
value = container.Get("not-exist") // Will panic
```
