Command completion becomes central in IntelliJ IDEA

JetBrains has introduced a major update to IntelliJ IDEA, focusing on command completion as the primary interface for developers. This feature allows users to access powerful IDE tools directly from the code editor by typing .., which brings up intelligent actions tailored to the current context and cursor position.

New logging features simplify debugging

The update includes easier access to logpoints, an alternative to traditional println() statements. Developers can now insert logpoints directly via command completion by typing .. above an expression or block. This change helps transition users to cleaner, more efficient debugging practices.

AI assistance integrated into command workflow

Contextual AI assistance is now accessible through the same .. command. Developers can request explanations of complex methods, generate documentation, or refactor code without switching tools. The IDE provides rich context to AI agents, including the current file, language, and selected expression.

Unified interface for completion workflows

JetBrains has unified postfix completion, dynamic templates, and command completion into a consistent interface. Users will notice clearer filtering, cleaner preview panels, and more intuitive search directly from the contextual completion window. This change improves usability across different coding tasks.

Expanded support for various file types

Command completion is now available in more contexts, including binary files and decompiled code. It has been extended to support structured and framework-specific environments such as property files and Spring workflows. Support for build scripts is expected to be added soon.

Command completion redefines how developers interact with IDEs

Unlike traditional auto-completion, command completion changes how developers discover and use IDE features. Instead of relying on menus or keyboard shortcuts, users can trigger actions directly from their code. This approach provides relevant suggestions based on syntax, scope, and available actions at any given moment.
