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

Implicits are magical. But every wizard knows that any sufficiently complex magic requires a good enough magic wand. In the case of implicits, the Scala plugin can work just as well, or maybe even better. You can already use View | Show Implicit Hints (Ctrl + Alt + Shift + "+") to see beyond appearances: The Scala plugin can show you how impicits are derived and where they come from (NB: "ambiguous", not "amphibious"; see more of this in action). So far so good, but suppose that implicits are not yet there: If you have a pre-2020.2 version of the plugin installed, feel free to co

It may well be that you haven't considered contributing to any open source project, let alone the IntelliJ Scala plugin. However, if you use IntelliJ IDEA to write Scala code, it's actually a very reasonable thing to do. Here's how you can benefit from contributing to the plugin code base. There's a common misconception about attracting contributors where the process is viewed as "a way to get developers for free." Nothing could be further from the truth, at least in our case. While the Scala plugin code is open source, there are currently 10 people in the Scala team at JetBrains working on
