# Not just another Init macro

`Not just another Init macro` is a Swift macro to automatically generate an initialiser for a `struct` or `class`.
It is supercharged with features to make it as flexible as possible.

## Features

- Retrieves inferred basic data types, arrays and dictionaries
- Support for arrays and dictionaries containing nil values.
- Support for casting.
- Support for escaping closures.
- Ability to generate a public or private initiliaser.
- Ability to omit variables from the initialiser.
- Ability to provide default values for variables in the initialiser.
- Diagnostic messages to avoid typos, wrong access level, etc..

## Usage

```swift
@Init(accessLevel: .internal, defaultValues: ["key2": true], exclude: ["key4"])
public struct Test {
let key: String
let key2: Bool
let key3: Int
var key4 = ["HI", "Bye"]
var key5 = [3, "Int"] as [Any]
var key6 = ["key": "value"]
var key7 = ["key": "value", "anotherKey": 1] as [String: Any]
var key8 = ["key": "value", 1: false] as [AnyHashable: Any]
var key9 = 3.0 as Float
var key10 = 3.0
let optionalKey: String?
var optionalKey2 = [3, nil]
var optionalKey3 = ["key": nil] as [String: Any?]
var optionalKey4 = [1: nil, 2: "value"]
var optionalKey5 = 3.0 as Float
var closure: (Int) -> ()
}
```
will generate:

```swift
internal init(
key: String,
key2: Bool = true,
key3: Int,
key5: [Any],
key6: [String: String],
key7: [String: Any],
key8: [AnyHashable: Any],
key9: Float,
key10: Double,
optionalKey: String?,
optionalKey2: [Int?],
optionalKey3: [String: Any?],
optionalKey4: [Int: String?],
optionalKey5: Float,
closure: @escaping (Int) -> ()
) {
self.key = key
self.key2 = key2
self.key3 = key3
self.key5 = key5
self.key6 = key6
self.key7 = key7
self.key8 = key8
self.key9 = key9
self.key10 = key10
self.optionalKey = optionalKey
self.optionalKey2 = optionalKey2
self.optionalKey3 = optionalKey3
self.optionalKey4 = optionalKey4
self.optionalKey5 = optionalKey5
self.closure = closure
}
```
