What's new in RubyMine

2019.2 (Jul 29)

RubyMine 2019.2 adds support for Rails 6 and Ruby 2.7, improves YARD support and the debugger, and incorporates many platform improvements. Check out all the new things below and update today. We also encourage you to let us know of any issues and join the RubyMine Slack!

Debugger

Debugger speed comparison v2019.1 v2019.2

Faster debugger

Our debugger used TracePoint :line to trace the program execution line by line. For v2019.2, we have designed a native extension for MRI that lets the debugger choose at which fragments of code the execution should be suspended, and free the rest of the code from overhead. As a result, we've been able to dramatically speed up the debugger and implement the new features below.

Smart Step Into

Smart Step Into

Previously, if you stumbled across a line with lots of methods in a debug session, RubyMine was only capable to step into the first method in a line. The newly added Smart Step Into lifts this restraint and allows you to step into and investigate every particular method or a block call located on the same line.

Block breakpoints

Block breakpoints

With the new version you can set breakpoints not only at lines but also at blocks. When you click the left gutter to set a breakpoint at a line that contains a block, RubyMine will ask if you want to set a breakpoint at a line, block, or both.

Ruby 2.7

Pattern Matching

RubyMine 2019.2 supports Pattern Matching, which was introduced in the first preview of Ruby 2.7 as an experimental feature. The IDE identifies the new syntax and helps you navigate, find usages, and rename the objects.

Numbered block parameters

Numbered block parameters

The new version of RubyMine recognizes the syntax of numbered parameters and shows/finds their usages. This is one more experimental feature of Ruby 2.7 which allows you to assign values in blocks using a parameter number as a default parameter, instead of defining a block variable.

Rails 6

Action Mailbox support

Action Mailbox

RubyMine 2019.2 supports Action Mailbox which will ship with Rails 6. The IDE suggests autocompleting routing methods and callbacks, and navigates between their implementations and usages.

Action Mailbox inspections

We’ve also added a couple of inspections that let you know if you’ve forgotten to add a routing call in ApplicationMailbox and a process method in your mailbox. The latter also offers a quick-fix.

Learn more about how to use Action Mailbox in this detailed GoRails episode.

Enum support

We've added proper code insight support for ActiveRecord::Enum. This includes code autocompletion, navigation, and finding usages for enums’ names and methods. Negative scopes for enums, introduced in Rails 6, are supported as well.

YARD

Improved YARD support

Improved YARD support

We’re gradually improving our support for YARD to help you create and manage YARD tags, and get better code autocompletion in RubyMine based on YARD annotations. The new version adds proper type annotation and inspections for @overload and @yieldparam tags.

Read YARD support in RubyMine for a detailed overview of RubyMine’s features and fresh improvements around YARD.

Factory Bot

Rename factories

Rename factories

With v2019.2 you can rename (Shift+F6) factories, sequences, and traits. The IDE finds their definitions and suggests renaming it and all usages, as well as the file name if it matches the factory name.

We've also added factories, sequences, and traits to the File Structure view (Cmd/Alt+F7) and popup (Cmd/Ctrl + F12), and added the ability to safely delete them (Refactor | Safe Delete).

JavaScript

Destructuring intentions

New intention actions

The new Propagate to destructuring intention (Alt-Enter) allows you to replace an extra variable if possible with another destructuring. To remove a destructuring completely, use the intention action called Replace destructuring with property or index access.

Dynamic usages in Refactoring Preview

Improved Rename refactoring

When you rename a symbol in a JavaScript or TypeScript file, the IDE now groups together dynamic usages and, by default, excludes them from the refactoring. This makes the refactoring more accurate and gives you more control over what exactly should be renamed in the Refactoring Preview tool window.

Vuetify props

Better support for Vue.js component libraries

Code completion for components and their props from Vuetify, BootstrapVue, Quasar, and some other Vue component libraries is now more precise. This was made possible by a new approach we’ve adopted to working with these libraries in the IDE.

Duplicate code inspection

Searching for duplicate code

The new Duplicate code fragment inspection checks your code on the fly and immediately highlights potential duplicates in the editor. It works for JavaScript, TypeScript, CSS, Sass, SCSS, and Less.

See what's new in WebStorm for more of the JavaScript improvements available in RubyMine 2019.2.

Code style

Edit code style configurations

Improved EditorConfig support

With v2019.2 you can maintain different code styles in different parts of your projects by adding multiple .editorconfig files. In addition to the standard EditorConfig options, which have been supported for a long time, you can now use IDE-specific properties that cover all available IDE code style options.

Shell scripts

Shell script editing

Edit Shell scripts

The new version adds support for shell scripts. This includes code completion, quick documentation, textual rename for .sh and .bash files, and run configurations for shell scripts. The IDE also integrates with ShellCheck for linting and shfmt for formatting the code.

Git

.gitignore autocompletion

Autocompletion in .gitignore

In .gitignore files, the IDE now offers code completion suggestions for files and folders. Cmd/Ctrl-click on the name to jump to this file or folder in the Project tool window. You can also quickly add files to .gitignore from the Project view and Local Changes tab – right-click on it and select Add to .gitignore.

Database tools

Improvements in Database tools – Full-text search

Find data with Full-text Search

Now you can search for data in your databases even if you don’t know where it is located. Right-click the data source that you want to search through and select Full-text Search (Ctrl+Alt+Shift+F / Cmd+Alt+Shift+F). The results of your query will be filtered to show only those strings in which the data is found.

See what’s new in DataGrip for the other database improvements that are also available in RubyMine 2019.2.

Other improvements:

  • Standard gem support
  • Support for Action Text
  • Support for Cucumber 4
  • Minor UI improvements in the Version Control tool window
2019.1 (Apr 4)

Docker

Docker-compose exec

Rethink Docker with docker-compose exec

RubyMine adds support for
docker-compose exec. Simply put, this command when enabled allows you to run and debug applications, install gems and do other development tasks faster than before.

Read How to work with Docker/Docker Compose from RubyMine for details.

Experimental: Run with docker compose.

Speed RubyMine up

In Experimental features, enable ruby.docker.internal.via.exec to speed up RubyMine when you're working with a Docker SDK.

Now you can add gems, run rake tasks, rails commands and other things that update your environment, without rebuilding Docker images.

Recent locations

Recent locations

Recent locations popup

The new Recent Locations popup reinvents the way you navigate your codebase. This popup helps you find the actual code when you only remember what it was about, but don’t have any idea where you have seen it. Start typing to filter the results and jump to the code you need.

Read RubyMine Navigation: Recent Locations Popup for details.

Profiler

Create i18n translation

Profile applications

RubyMine 2019.1 integrates rbspy and provides a native profiler to help you discover parts of code that slow down your application and/or tests.

For a detailed tutorial, read Profile Ruby & Rails Apps With rbspy in RubyMine.

Attach profiler to running app

Attach to running apps

Note that you can attach the profiler (Find action / Attach Profiler to Process) to your running application and investigate it in real time!

Factory Bot

Autocomplete and navigate attributes

When you are adding a factory, RubyMine autocompletes its attributes and, if possible, their values too. For instance, for a Rails model factory, the IDE will autocomplete its fields with their content, and even associations. And of course you can navigate between the definitions and usages of those objects.

Complete factory creation methods in test files

Autocomplete and navigate methods

When you are writing tests, you can autocomplete and navigate to the definitions of factory creation methods, such as create, build, build_stubbed, and others.

Other cool features of Factory Bot, such as sequences, traits, and aliases are also fully supported.

Full MVC integration

We also added factories to the Related files popup (Navigate / Related symbol), and added a gutter that allows you to go to partial factory declarations if they exist.

Call Hierarchy

Call Hierarchy

Investigate method calls

The new Call Hierarchy action helps you dig into methods (“callers”) that use the method you are investigating, the methods that call these callers, and further as deep as you need.

For more information, refer to this blog post.

TruffleRuby

TruffleRuby

TruffleRuby support

RubyMine 2019.1 adds support for TruffleRuby! To switch your current Ruby SDK to TruffleRuby, make sure you have the interpreter installed, and choose it in the Ruby SDK settings.

By the way, in this release we also fixed many issues with Ruby version managers.

JavaScript

TypeScript in Vue

Improved support for TypeScript in Vue apps

RubyMine now uses the TypeScript language service together with its own TypeScript support for any TypeScript code in .vue files. This means that you’ll now get more accurate type checking and type info, you will be able to use the quick-fixes provided by the service, and see all the TypeScript errors in the current file in the TypeScript tool window.

Highlight errors in tests

Highlighting for failed line in test

When you run tests with Jest, Karma, Mocha, or Protractor and some tests fail, you can now see right in the editor where the problem happened. The IDE will use the information from the stack trace and highlight the failed code. On hover, you’ll see the error message from the test runner and you can immediately start debugging the test.

New debugger console

New debugger console

Meet the new, improved interactive debugger console in the JavaScript and Node.js debug tool windows! It now displays objects using a tree view, and it supports styling of log messages with CSS and grouping them using console.group() and console.groupEnd(). You can also filter out any type of log messages.

New debugger console

Completion for npm scripts

When adding new scripts to the package.json file, the IDE now provides suggestions for available commands provided by the installed packages. After typing node, the IDE will suggest folder and file names. And after typing npm run, you’ll see a list of tasks defined in the current file.

See what's new in WebStorm for more of the JavaScript improvements available in RubyMine 2019.1.

HTML & CSS

HTML and CSS

Updated documentation

The documentation (F1) for CSS properties and HTML tags and attributes now shows up-to-date descriptions and information about the browser support from MDN as well as links to the full MDN articles.

Custom themes

Custom themes

New UI themes

You can now use the new colorful UI themes in RubyMine that are available as plugins. Choose between the Dark Purple, Gray, and Cyan Light themes, or create your own.

Database tools

  • Support for new databases: Greenplum, Vertica, and Apache Hive
  • Code completion supports combined statements for CREATE and DROP
  • Support for DEFINER attributes in MySQL and MariaDB
  • Support for the Oracle mode in MariaDB
  • You can now set the default folder for a project

2018.3 (Nov 22)

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.

Read i18n features in RubyMine for other internationalization improvements made in v2018.3.

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
  • High-contrast theme
  • Safe delete in i18n
