# CoreEvents
Small Swift events kit that provides some base types of events:
- [`FutureEvent`](#futureevent)
- [`PresentEvent`](#presentevent)
- [`PastEvent`](#pastevent)
## FutureEvent
Simple event.
Provides classic behaviour.
### Description
This is classic event (like C# `event`) that can contain many listeners and multicast each new message for this listeners.
This event emits **only** new messages. It means if you add a new listener to existed event then last will not emit previous messages to the new listener.
### Types
- `FutureEvent: Event`
### Example
```swift
var event = FutureEvent()
event += { value in
print("Awesome int: \(value)")
}
event.invoke(with: 42)
```
will print `Awesome int: 42`
## PresentEvent
### Description
This event provides all `Future` logic, but additionally provides emiting last emited value for a new listener.
It means if your event already emits value and you add a new listener then your listener handles previous emited value in the same time.
### Types
- `PresentEvent: Event`
### Example
```swift
var event = PresentEvent()
event += { value in
print("Awesome int: \(value)")
}
event.invoke(with: 42)
event += {
print("Old awesome int: \(value)")
}
```
will print:
`Awesome int: 42`
`Old awesome int: 42`
## PastEvent
### Description
This event is like the Present, but emits all previous messages for a new listener
### Types
- `PastEvent: Event`
### Example
```swift
var event = PastEvent()
event.invoke(with: 0)
event.invoke(with: 1)
event += { value in
print("Awesome int: \(value)")
}
event.invoke(with: 2)
```
Will print:
`Awesome int: 0`
`Awesome int: 1`
`Awesome int: 2`
## How to install
`pod 'CoreEvents', '~> 2.0.1'`
We also support SPM:
`.package(url: "https://github.com/surfstudio/CoreEvents", .exact("2.0.2"))`
## Warning
In one file you can not use just `add`, you should specify a key - `add(key: String, _ listener: Closure)`
## Versioning
Version format is `x.y.z` where
- x is major version number. Bumped only in major updates (implementaion changes, adding new functionality)
- y is minor version number. Bumped only in minor updates (interface changes)
- z is minor version number. Bumped in case of bug fixes and e.t.c.
