​​Great talk about porting FP stuff to #kotlin.

​​Have you ever wanted to stransform #json to #ts or #go struct? Maybe even to #kotlin or #rust.

Well, http://transform.tools allows you to do just that!

It is even not limited to json, but also works with #svg, #graphql, #css, and many other tools.

​​A kotlinx.html library provides DSL to build HTML to Writer/Appendable or DOM at JVM and browser (or other JavaScript engine) for better Kotlin programming for Web.

http4k is a lightweight but fully-featured HTTP toolkit written in pure Kotlin that enables the serving and consuming of HTTP services in a functional and consistent way. http4k applications are just #kotlin functions which can be mounted into a running backend. For example, here's a simple echo server:

 app: HttpHandler = { request: Request -> Response(OK).body(request.body) }
val server = app.asServer(SunHttp(8000)).start()

Kotlin source code documentation management tool.

This is a tool that produces #kotlin source example files and tests from markdown documents with embedded snippets of Kotlin code. It also helps to add links to the API documentation website into the documents and has a few other helpful markdown-management features.

Similar to doctests in Python. My ❤️ type of tests!

Monorepo of all tooling to continuously test and deliver #android apps to users from AvitoTech.

Pretty impressive set of tools!

​​Λrrow is a library for Typed Functional Programming in #kotlin.

Arrow aims to provide a lingua franca of interfaces and abstractions across Kotlin libraries. For this, it includes the most popular data types, type classes and abstractions such as Option, Either, IO, Functor, Applicative, Monad to empower users to write pure FP apps and libraries built atop higher order abstractions.

Arrow is a family of different projects, including:

- Arrow Fx is a next-generation Typed FP Effects Library that makes effectful and polymorphic programming first class in Kotlin, and acts as an extension to the Kotlin native suspend system.
- Arrow Optics offers an Optics DSL to compose different Optics while improving ease of use and readability. To avoid boilerplate, Arrow will generate this property-like DSL using @optics annotation.
- Λrrow Meta is a meta-programming library that cooperates with the Kotlin compiler in all its phases, bringing its full power to the community.
