Kotlin Dialect (KD) is a set of tools and rules to write logic in Kotlin for several platforms.

If you know what Kotlin Multiplatfrom is, you probably wonder what's the fuss. However, if you tried Kotlin Multiplatform you surely know how hard it is to set up correctly for multiple platforms. This project dictates one particular way to have your code organized to be able to have single logic in Kotlin across platforms in native apps.

Key features:

• Redux-like architecture with Controller/Context (aka Store), Shoulds (aka Reducers), and Effects
• Klin, a translator to convert YML to target languages: Kotlin, Swift, C++

Usage

dist/ directory contains the latest Klin version

Klin is a small Node.js application (generated out of Kotlin Dialect source code, of course).

Install prerequisites to run Klin:

№	Prerequisite	Linux	macOS	Windows (MSYS2)
1	Node.js	?	brew install node	pacman -S mingw-w64-x86_64-nodejs

Second, run Klin to generate source code out of YML:

$ node dist/app.js --file=/path/to/kd.yml

Building Klin from source

As a user, you don't need it. However, if you feel adventurous, first install dependencies:

№	Prerequisite	Linux	macOS	Windows (MSYS2)
1	Gradle	??	brew install gradle	??

Second, build the application:

$ ./util/build-klin

Third, distribute the application into dist/ directory:

$ ./util/dist-klin

Generation of Kotlin entity fields

№	YML type	Kotlin type	Default value	YML example	Kotlin example
1	Bool	Boolean	false	didLaunch: Bool	var didLaunch: Boolean = false
2	Double	Double	0	angle: Double	var angle: Double = 0
3	Int	Int	0	selectedItemId: Int	var selectedItemId: Int = 0
4	Long	Long	0	timestamp: Long	var timestamp: Long = 0
5	String	String	""	method: String	var method: String = ""
6	Type	Type	Type()	request: NetRequest	var request: NetRequest = NetRequest()
7	[Type]	Array<Type>	arrayOf()	arguments: [String]	var arguments: Array<String> = arrayOf()
8	[TypeA: TypeB]	Map<TypeA, TypeB>	mapOf()	templates: [String: String]	var templates: Map<String, String> = mapOf()

Supported C++ entity field types

Since Kotlin Native only generates a pretty ugly C code out of Kotlin, Klin generates C++ wrappers to achieve almost the same look&feel in a C++ Qt app.

№	YML type	C++ type
1	Bool	bool
2	Int	int
3	String	QString

Why Qt? Because Qt has QML, a declarative UI.
