機能

AI Assistant

• AI Assistant major upgrade
  • JetBrains AI Assistant has received a major upgrade, making AI-powered development more accessible and efficient. With this release, all JetBrains AI features are accessible for free in RubyMine, with unlimited use for some, such as unlimited code completion and local model support, and limited credit-based access to others. JetBrains are also introducing a new subscription system that makes it easy to scale up as needed with the AI Pro and AI Ultimate tiers.
• New model used for cloud-based code completion
  • This release now uses JetBrains new Mellum model to support AI suggestions for RBS. This improvement ensures faster code generation and allows you to filter out invalid suggestions.
• Inline prompts
  • You can now use natural language prompts directly in the editor to enhance your RBS coding with the help of AI Assistant.
• Annotator support
  • RubyMine 2025.1 comes with support for annotators, enabling error inspections and syntax highlighting in AI code suggestions.
• Smarter AI context awareness
  • AI Assistant now better understands your entire project, using advanced RAG-based retrieval to work with the most relevant files, methods, and classes. In addition, context now includes recently accessed files, making interactions even more relevant to your workflow. You also maintain full control over the AI’s context. You can add or remove attachments that are sent as context.
• More AI models available
  • You can take full control of your AI experience in RubyMine by choosing from the latest and most advanced models:
    • Claude 3.7 Sonnet.
    • OpenAI GPT-4.1 (сoming soon).
    • Gemini 2.0 Flash.
• Offline mode: Work with local models
  • RubyMine 2025.1 supports offline mode, which means you’ll never have to manage without AI Assistant again. With the Ollama and LM Studio local models, all AI-power coding assistance is still available even when there’s no internet connection.
• Multi-file changes in AI chat’s edit mode
  • AI Assistant now uses the retrieval-augmented generation (RAG) technique to locate the most relevant files and suggest changes across your project within one chat interaction.
• Faster application of code snippets from the chat
  • The upgraded AI chat now does more than just suggesting code snippets – it also finds the right spot for inserting newly generated code after you click Apply. With manual copy-pasting out of the way.
• Exclude files from AI context
  • In RubyMine 2025.1, you can tell AI Assistant what to ignore by configuring an .aiignore file. This allows you to make sure AI does not access files or folders that contain sensitive data.

Ruby

• Warning on creating constants in the global Ruby namespace
  • RubyMine now displays a warning when you create constants or modify the global Ruby namespace.
• Error when using keyword arguments in index assignment expressions
  • In Ruby 3.4, an error is triggered when using keyword and block arguments inside index assignments. JetBrains implemented an inspection displaying such errors and a fix that you can quickly apply in your IDE.
• Improvements for the Incorrect argument count inspection
  • JetBrains refined the Incorrect argument count inspection to better track block usage in method definitions. JetBrains also improved the handling of complex super calls, enhanced warning messages, and lowered the inspection severity level to Warning.
• Hash.new accepts the capacity keyword
  • RubyMine no longer displays unknown keyword warnings when passing the capacity parameter to the Hash.new method.
• Support for asdf 0.16+
  • RubyMine 2025.1 supports the latest version of asdf to make sure interpreters installed with this version manager are recognized properly. This fixes any issues you might have previously encountered in RubyMine when using the re-written 0.16 version of asdf.

Rails

• Updated deploy.yml schema for Kamal 2.4.0 and 2.5.0
  • To address the changes introduced in Kamal 2.4.0 and 2.5.0, JetBrains added code insight support for a number of deploy.yml keys, including:
    • accessories.network
    • accessories.proxy
    • accessories.registry
    • builder.provenance
    • builder.sbom
    • proxy.hosts
    • ssh.config
• Options to disable auto-reloading of Rake tasks and Rails generators
  • JetBrains added two advanced settings to control the automatic refreshing of Rails generators and Rake tasks. When the settings are disabled, only manual reload actions are available.
• Notifications on Rails generator loading errors
  • JetBrains improved the UX of Rails generator loading errors by replacing the focus-stealing tool window notifications with less intrusive balloon notifications.

Other Features

• Option to align binary expressions
  • A new formatter setting in RubyMine allows you to align binary expressions in if and while conditions, assignments, return statements, and function calls without parentheses. This new setting is designed to adhere to the behavior of RuboCop.
• Updated terminology
  • JetBrains revised the terminology throughout the user interface, replacing Ruby SDK with Ruby interpreter for clarity and consistency.
• Bundled .env files plugin
  • RubyMine 2025.1 comes with the pre-installed .env files plugin, which is widely used to manage configuration settings, environment variables, and sensitive information.

User Experience

• Native OS file dialogs on Windows
  • RubyMine 2025.1 features native Windows file dialogs, which are part of the default settings.
• New file creation in the Project tool window
  • RubyMine 2025.1 simplified the procedure of creating files. Right after you click the + icon in the Project tool window, you can choose the required file template from the resultant popup list, which is easily filtered using the search field.
• Automatic plugin update option
  • You can instruct RubyMine 2025.1 to automatically update plugins in the background. The setting downloads available and compatible updates and applies them on the next RubyMine restart.

VCS

• Enhanced diff view
  • You can now see commit details directly in the diff view. This helps you analyze the file history and modifications more quickly and easily.
• Discontinuation of the modal commit interface For a number of reasons, RubyMine 2025.1 no longer features the modal commit interface. This option is still available as a separate plugin, though.

Remote Development

• Containerfile support
  • RubyMine 2025.1 comes with built-in Containerfile recognition, which ensures a smooth developer experience when using various tools for remote solutions in the same environment. Whether it’s Docker, Podman, or Buildah, it can all be configured in the same file, fully recognized by the tools of your choice, with full support for syntax highlighting, linting, and snippet suggestions.
• Improved editing in RemDev
  • With reduced typing, highlighting and formatting latency, RubyMine 2025.1 ensures a better overall editing experience in remote development.
