What happens when you combine one obscure IntelliJ IDEA feature with two obscure Scala features? If you choose the right ones, their obscurities just might cancel each other out, so that instead making everything far more opaque you can get an intuitive and internally consistent system. Let's see how the upcoming version of the Scala plugin combines package prefixes with chained package clauses and relative imports. The problem with packages Both Java and Scala use reverse domain name notation for packages. According to the Scala Style Guide, you should write package org.example.application ra

Because Scala is a curly-bracket language, adding and removing curly braces is an integral part of Scala programmers' everyday life. Those actions compound, so every improvement in this area matters. To understand the new advances, let us first take a take a look at it from historical perspective (or just watch this). Before At the beginning, there was no IDE assistance, so you had to tinker with curly braces manually: https://blog.jetbrains.com/wp-content/uploads/2020/07/braces-1.mp4 Not only did this require more keystrokes, but the code was not valid for long. It was not good... But now, t

Although we won't have Scala Days this year, the Scala Love conference is all the rage. The technology lets us transcend physical boundaries – we can unite while being far away... well, at least as long as there are tickets left ;) Owing to high demand, the IntelliJ Scala team has volunteered to extend the conference by hosting a third track called Harmony, in addition to the two existing ones, Joy and Happiness: Feel free to submit a talk in the extra Call for Papers (closed). Register to attend the Harmony track. Schedule (Google Calendar) 11:45 – 12:00 CEST / 02:45 – 03:0

We added basic Dotty support in the IntelliJ Scala plugin a long time ago, right after the announcement of Dotty. However, for a long time Dotty has been a dark horse, and aiming at a moving target hadn't been easy. So it was reasonable to put that task on the back-burner and focus on Scala 2 for a while. Now that Dotty is finally destined to become Scala 3 and the language features are getting more stable, we have started to work on a full-fledged Scala 3 support. The 2020.1 Scala plugin nightly builds now include preliminary support for Scala 3: the new syntax (by the way, we had to adjus

They say "with great power comes great responsibility." Because of the IntelliJ Scala plugin's huge user base, most default settings tend to become de-facto standards in the Scala community, so we strive to choose the defaults wisely. Moreover, we believe that sometimes such kind of decisions are worthy of detailed explanations, and subject to approval by the community. As experience has shown, many introduced novelties are often misunderstood and criticized in the beginning. For example, method signature enforcement was initially touted as some quirk that only keeps getting in the way. But

As some of you may know, this June the whole Scala plugin team took a break and went to Berlin to enjoy Scala Days 2014, and of course to meet IntelliJ IDEA users! Alexander Podkhalyuzin, a lead developer of the Scala plugin, used this chance to catch Jason Zaugg, a Scala rockstar and developer at Typesafe, and talk about Scala Compiler, Dotty and IntelliJ IDEA. Enjoy the interview! Alexander: How did you first hear about Scala? Jason: A colleague of mine saw Martin Odersky present Scala at a conference in 2008. He shared his impressions of the language at our team’s weekly tech talk, an

The Scala community knows that the place to be on June 16th - 18th is Scala Days 2014 conference. So, the entire team behind the IntelliJ Scala plugin went to Berlin to embrace the awesomeness of this event. Besides attending the talks (I wish I had enough time to hear them all), we delivered our own presentation Good to Great: IntelliJ IDEA and Scala (hosted by Alexander). We also had a booth with amazing giveaways that included IntelliJ IDEA Yo-Yos (and stickers): Everyone likes IntelliJ yo-yos :) We hand out 150 of them at #ScalaDays. pic.twitter.com/57JwCYOTBA — Pavel Fatin (@pav

A few weeks ago Alexandr Podkhaliuzin, lead developer from JetBrains was invited to SF Scala to give a talk about Scala support in IntelliJ IDEA. In his presentation he talked about Scala language and its non-trivial technical aspects which make development more complicated as compared to other languages, and how the IntelliJ IDEA helps developers to overcome these complications and essentially be more productive. The presentation mentions both well-known and brand new features, which will be available in the nearest release. After a short delay we'd like to share the video and slides fr

We know that you have been waiting for SBT project support in IDEA too long. That's why we make SBT plugin nightly builds available even before an actual release of the plugin.Features Though work on SBT plugin is still in progress, the following features are already available: SBT project import. Incremental project model updating. Auto-import (on project definition changes). Editing of .sbt files (with full highlighting, auto-completion and navigation). Many more features are on the way (see the roadmap below). Installation SBT plugin is currently available for ID

Thanks to everyone who joined us last week in New York City for Scala Days 2013. We were impressed by how many passionate developers came to the conference. Special thanks to James Ward and TypeSafe for inviting us to such a great event. It was also a pleasure to see a lot of the attendees at our session Scala Developer Tools in IntelliJ IDEA, where we presented the new features of the IDE for Scala developers, and announced the early preview of SBT support. We hope to post a recording of this session soon so everyone can watch it. In the meantime you can see the slides from
