Historically debuggers were used to help locate and fix bugs. Nowadays, the debugger in IntelliJ IDEA can help you do much more than that. We’ll show how the debugger helps make the development process more productive.

We’ll explain how some debugger features like lambdas debugging, smart step into, and async stack traces work and how it is possible only because of the tight integration with other IDE features.

You will also learn new ways to use the IntelliJ IDEA debugger in your everyday work.

This is the story of a developer. An ordinary developer, just like you, who adapted to whatever technologies, tools or IDEs the working environment dictated. After nearly ten years of developing Java applications, this developer started using “just another IDE” – IntelliJ IDEA.

That was fifteen years ago. This developer discovered, through working with other developers who really understood their tools, how IntelliJ IDEA made them more productive, and how getting into the “IntelliJ Flow” made them happier.

This developer is Trisha, and she’d like to share with you some of her favorite things about IntelliJ IDEA. How the way it works and the features it provides make her job easier and, crazy though it may seem, how it makes her smile while she’s coding.

Many developers, sooner or later, come to a point where they realize none of the existing tools can do exactly what they want. For example, the vendor of your favorite IDE hasn’t implemented a feature you’re using, or you’re working with a rather new custom framework that isn’t yet supported by your IDE. What to do? The good news is that IntelliJ IDEA and its plugins are not set in stone, so anyone – yes, that includes you – can implement support for a new language, library, or framework.

In this talk, Yuriy will tell you how all those who contribute to IntelliJ IDEA keep up with innovations in cyberspace, implementing IDE features for popular technologies.

With IntelliJ IDEA’s 4-month release cycle, JetBrains has adapted well to Java’s 6-month release cycle. Up-to-date support for new language features in the IDE ensures that it’s always easy for developers to play with the new features.

IntelliJ IDEA sets a fairly high bar for itself in terms of supporting new Java features. IntelliJ IDEA supports not only error highlighting and code completion, but also build tools for automatic migration to new code constructs. It adapts its existing set of inspections and code assistance tools so that they correctly interact with the new features and make use of them when appropriate. From this talk you’ll take away how to use the latest language features, how they work with the existing coding assistance in IntelliJ IDEA, and how you can improve your code by using these features.

Indexing is what IntelliJ IDEA needs to do to learn all about the project we open. This is the cost we pay to make the IDE smart so that it can help us with our daily tasks, be that for reading, writing, completion, navigation, renaming symbols, or refactoring our code.

Can we make IntelliJ IDEA index our projects faster? Many times faster? YES! Join Eugene to learn more!

We start the talk with a basic explanation of what indexing does in IntelliJ IDEA and how indexes are used by smart features. Next, we’ll discuss how we can share indexes and shorten the indexing time. What indexes are shared or how they are delivered to an IDE is our next topic. You’ll learn about our experiments and outcomes and see how the IntelliJ IDEA codebase indexing time has been halved recently.

As an outcome, you’ll learn how to apply this to all your projects.

It would be difficult for a developer to work without a version control system, and everyone needs decent tools to handle all VCS-related tasks. We believe having great VCS integration within the IDE is essential to being productive, which is why we invest a lot of effort in making both routine and complex tasks easier. But is it at all possible?

In this talk, we’ll look at Version Control integrations in IntelliJ-based IDEs, exploring their history, evolution, current state, and future plans.
