IntelliJ

After my last NixOS update IntelliJ started behaving weirdly. Not always, just sometimes. The autocomplete popup opens, maybe remains open for a keystroke or two. Then suddenly disappears. Same with the “Copy Path/Reference…” popup from the context menu, the one where you pick absolute path, relative path, package name and so on. Pretty annoying, especially when you’re in the middle of typing. And every time the popup vanished, the whole window seemed to flicker once, as if IntelliJ was reacting to a resize event....

In a way, this is the last part of my journey creating a Java (Line) Coverage Analyzer. This article concentrates on creating an IntelliJ plugin, that adapts it to show the results collected by the analyzer created in Let’s create a Coverage Analyzer, Part 4. To get started, check out JetBrains’ Developing a Plugin article. With recent IntelliJ versions you need to install the Plugin DevKit first, then create a new Project and select the IDE Plugin Generator....
