What's new in RubyMine

2018.3 (Nov 22)

RubyMine 2018.3, the final major update for RubyMine this year, is now available for your review! Check out the new features below and give it a try. Don't forget to share your feedback!

Code Insight

Support for Rails scopes

Rails scopes

The IDE now understands Rails scopes much better. For example, when you add an association object to your scope, RubyMine will suggest available finder methods. You will also discover code autocompletion and navigation for chained scopes.

Struct support

Struct

RubyMine adds full support for Struct. Now you can autocomplete, navigate, and refactor objects of Struct classes the same way you do with any other Ruby classes and their instances.

Nullability analysis for Ruby

Nullability analysis for Ruby

A new Nil dereference inspection will check your code for possible nil errors in the current context, like when you call a method on a variable that might be nil.

Internationalization

Creating I18n translations

Use the new I18n dialog to create translations for all your dictionaries at once. Just like before, put the caret on a string, press Alt+Enter, and choose to i18nize it. Then, once generated, hold Cmd/Ctrl and click the created key to navigate to any existing translation.

Scopes and lazy keys

You can also create translations for namespaced keys and lazy lookups with no extra effort, as the new version of RubyMine lets you create translations for such keys right from the editor.

Translation previews

RubyMine can show you actual translations instead of I18n keys – just press Cmd./Ctrl. on any key in a controller or a view file. You can even choose which dictionary should be used as a translation preview.

Refactoring

New Extract Parameter dialog

Extract Parameter

The new Extract Parameter dialog (Refactor | Refactor this | Extract Parameter) allows you not only to extract an argument, but also to provide a default value for it, make it optional, or pass it as a block.

Inline refactoring improvements

Improved Inline refactoring

We've improved the Inline refactoring to let you get rid of of excessive methods and variables more safely. In particular, inlining methods with arguments and variables with string interpolation is now much more robust.

Extract Substrings to variables and constants

Extract substrings to variables & constants

Finally, we've added a very handy ability to extract parts of strings to variables and constants.

Read more about refactoring options in RubyMine Refactorings: Overview & Improvements.

New intention actions

Intention actions

New intention actions will help you make your code more readable. For example, you can now use the De Morgan's law intention to simplify ugly negations and extract block calls to methods. Just put your caret at a code smell and press Alt+Enter to apply an appropriate quick-fix.

Read about other new intentions in Intention Actions in RubyMine.

Tests

Test gutters

Test gutters

RubyMine 2018.3 also puts a handy gutter at each test method. These gutters are visual anchors that show you every particular test that can be run in a file. They also offer a faster way to run tests than the context menu does.

Read Running tests in RubyMine to learn about other handy testing features.

Git

Github pull requests

View pull requests

Now you can view GitHub pull requests right inside RubyMine. Go to VCS | Git | View Pull Requests to view the pull request’s description, labels, assignees, and the actual changes.

In addition, all the familiar features in the Git integration, such as update project, commit changes, view diff, and conflict resolution, now work with Git submodules.

User Interface

New Darcula color scheme

Renewed Darcula

The new Darcula theme gets rid of noisy colors, becomes easier on the eye, and better aligns with similar schemes designed for other programming languages in JetBrains IDEs.

The previous Darcula is still available, too. If you prefer to stay with it, go to Preferences / Settings | Editor | Color Scheme | Ruby, click on the gear icon, and choose Transform current scheme to Darcula 2018.2.

New Search Everywhere dialog

Search Everywhere

You will also discover the new, more convenient Search Everywhere dialog (Shift+Shift). It makes it easier to use all the other navigation dialogs – Go to Class, File, Symbol, and Action. Simply press Tab to switch between the search types.

New Plugins UI

Plugins UI

The updated Plugins section (Preferences / Settings | Plugins) makes it easier to manage, install, uninstall, and update plugins. For example, now you can search for plugins by tags, and sort the results by downloads, name, rating, featured, or updates.

JavaScript

Improved completion in Angular templates

Frameworks

As you work with Angular, enjoy improved code autocompletion and navigation for variables, pipes, and async pipes and the template reference variables.

In React apps, code completion now suggests all component lifecycle methods. The Unresolved variable inspection warns you about the possibly undefined components.

Autoimports in JavaScript

Autoimports in JavaScript

In JavaScript files, the IDE can now automatically add imports not only for symbols defined in your project, but also for symbols from the project’s dependencies. This works if the library has sources written as ES modules or a TypeScript type definition file.

Extract CSS ruleset

HTML and Style Sheets

The new Extract ruleset action (Alt-Enter) helps you quickly extract CSS declarations from one ruleset to a new, more specific one.

The code style for CSS and its preprocessors now has a configuration for the use of blank lines. Moreover, you can now sort the CSS properties inside blocks – alphabetically or in any custom order.

See what's new in WebStorm for more of the JavaScript improvements available in RubyMine 2018.3.

Markdown

Markdown improvements

Extracting reference links and more

The new Introduce reference action helps you create references for inline links. The IDE will find all the link duplicates in the file suggest replacing them with the newly created reference.

In addition, you can now strikethrough text and toggle header size. Find these new actions in the toolbar.

Other improvements:

  • Improved highlighting of keywords in conditional statements
  • Search for YAML values by flattened nested keys
  • Copy a path to a YAML value from breadcrumbs
  • Improved support for attr_accessors
  • Parameter hints in JavaScript files

Tests

Rerun failed tests

Now after you’ve run all tests in a file or directory, RubyMine provides an option to rerun the failed tests only, instead of rerunning all the tests. This frees you from manually picking up and investigating every failed test.

The new feature also works with presets like rake test and rake spec.

YAML

YAML code formatter

RubyMine now allows you to reformat YAML code. Select Code | Reformat Code, or press ⌥⌘L / Ctrl+Alt+L.

Code insight for anchors and aliases

You can now autocomplete and find usages of aliases when an anchor is defined, as well as navigate to the anchor and back.

Inline renaming for aliases and anchors is also available now. The IDE will warn you if you try to provide a name that conflicts with another existing anchor. It will not let you rename anchors using characters that aren’t allowed by the standard.

A number of basic YAML code inspections were added as well.

More YAML improvements

With this release you can autocomplete YAML data structures that have a JSON Schema file. The IDE automatically traces schemas from schemastore, but also provides a way to manually add and configure JSON schema files in the settings.

Finally, you can now quickly copy & paste a key path to a value in .yml files instead of typing out the full path.
