how to see the trees using the Scala compilers

Here’s a memo on how to show trees using the Scala compilers. While this likely won’t be relevant for normal usage of Scala, having the direct knowledge of the tree can be useful when developing tooling or during metaprogramming.

Use cases for Scala

Please help us to document the critical uses for Scala, for public good, for open source, for research or industry. This will enhance our chances to get funds and help us maintain the critical infrastructure for Scala.

EVENTS

ScalaWAW #33 - beach party! Jul 25th

It's high time for the legendary annual ScalaWAW beach party! The idea is pretty simple - no talks, no strict formula, just chill and enjoy the beach, the weather, and of course networking with fellow (not-only-Scala) programmers.

VIDEOS

A Remote Code Execution System with Apache Pekko & Scala

In this video we will demonstrate the features of Apache Pekko (the open source version of Akka) with a small project: a distributed remote code execution system, where a client sends a piece of code as text to be executed, and our system returns the output.

Tapir Tutorial - part 7: Integration with cats-effect & http4s

We've seen how to use Tapir in combination with direct-style, but one of Tapir's main strengths is that it integrates with virtually every Scala stack out there. This means, first and foremost, cats-effect for describing side-effecting computations, and http4s as an HTTP server. We'll include, of course, generating OpenAPI docs!

RELEASES

uPickle 4.0.0-RC1

A few breaking changes on the way - Shorten $type tag used for discriminating sealed trait cases, unbox first level of Options when serializing JSON.
