What’s New in RubyMine 2021.1

RubyMine 2021.1 will use .rbs files in its Code Insight. This means code completion will be improved for both Ruby’s standard library as well as for user code with RBS definitions. You don’t even have to use Ruby 3.0 in your project. The only requirement is that you include the RBS gem in it.

RubyMine also makes working with .rbs files simpler by providing features like code highlighting and actions such as Go to Declaration, Find Usages, and the Rename refactoring.

Have you tried JetBrains Space yet? You can now connect RubyMine to your organization there using the Space plugin. With it, you will be able to view and clone project repositories, review your teammates’ code, and write Space Automation scripts.

Code With Me, a new JetBrains service for collaborative development and pair programming, is now bundled with RubyMine.

It allows you to share the project you currently have open in your IDE with others and work on it together in real time. Your peers do not even need to have their own IDEs installed to collaborate with you.

Now when you have several tabs open in the split view, you can double-click the tab you’re working with to maximize the editor window for it. Double-click it again to return it to its original size.

You can now choose between different variations of the font you’re using, be it light, regular, or bold. To find the new options, go to Preferences/Settings | Editor | Fonts | Typography Settings.

You can now select all output in the built-in terminal. Right-click in the Terminal window and click the Select All action.

Alternatively, you can set up a shortcut. To do so, go to Preferences/Settings | Keymap and type “Select all” in the search field. You’ll find the required action under the Terminal section.

Sometimes you may want to run several tests that don’t belong to a single group, like one .rb file or a folder. Starting with v2021.1, you can hand-pick which test files to run. To do so, select the files in the Project view, right-click any of them, and pick Run ‘<test names>’ from the context menu.

MDN documentation is now bundled with RubyMine. This will help prevent connectivity issues with the MDN website and make in-editor documentation in your HTML, CSS, and JavaScript files display more quickly. In-editor documentation will also become more informative – for example, you’ll now see details about supported browser versions for JavaScript APIs.

We’ve made inspecting your CSS code with Stylelint easier. You can now fix problems with this popular linter in just a few clicks. Hover over a problem in your file or place the caret on it and press Alt+Enter, then select Stylelint: Fix current file.

Additionally, you can now specify a path to the configuration file under the corresponding field in Preferences / Settings | Languages & Frameworks | Style Sheets | Stylelint.

When working with style sheets, you can now check the specificity of your selectors – just hover over a selector that you want to check. Alternatively, focus on a selector and press Ctrl+Q to see this information in the Documentation popup.

We’ve added a new built-in browser preview to RubyMine. It allows you to quickly preview any changes you make to your HTML, CSS, and JavaScript files. Any changes you make in the IDE will be immediately saved and the preview will update on the fly.

To open the preview, click on the RubyMine logo icon in the widget in the top-right corner of the editor.

We’ve added a few improvements to the HTTP client. Now when you run HTTP requests, you can collapse the responses, change the output format, and quickly copy the response body to the clipboard.

We’ve improved the pull request process to make it more efficient. While creating a pull request, you can now select the desired branches, view the changed files and their diffs, leave multi-line comments, use PR templates, and create draft pull requests.

You can add Git commit message templates and use them in RubyMine. Define a template using a terminal command, and the IDE will display the text from it as an initial commit message.

You can now choose a code inspection profile before committing changes to VCS.

To create a profile, go to Preferences / Settings | Editor | Inspections. Then you can choose it in the Commit tool window: click the gear icon, select the Analyze code checkbox, click Configure, and choose the desired profile.

Sometimes, while comparing branches, you may want to get a file that doesn’t exist locally but only exists in a remote branch. Now you can do this using the Compare with branch dialog. Select the file you want to copy and click the arrow icon next to the Show diff button.

RubyMine now properly supports the JSON Lines text format. The IDE will recognize .jsonl, .jslines, .ldjson, and .ndjson file types.

RubyMine now supports JSONPath, a query language that makes it possible to find code elements in a JSON document, similar to XPath for XML. The IDE now has a new dedicated tool window which features search with code assistance and works for both JSON files and JSONPath expressions in code.

You can now configure how search will treat external dependencies. Open the Find in Files dialog (Ctrl+Shift+F), select Scope, and click the “…” icon next to the filters field. This will open the Scopes window, where you can see whether External Dependencies are included or excluded from the scope. You can change their status using the buttons on the right.

We’ve added a UI for editing grants when modifying database objects. The Modify user window, which you can invoke on a user in the database explorer with Ctrl+F6, now has a UI for adding grants to objects. This feature is available for PostgreSQL, Redshift, Greenplum, MySQL, MariaDB, DB2, SQL Server, and Sybase.

When you are focusing on a database object, you may want to run a certain query in the context of that object. We’ve added a new kind of live template which you can use just for that. For example, you can right-click on a table and pick Select first N rows from a table. You can also add your own templates and edit the existing ones.
