2017.1 (Apr 27)

RubyMine 2017.1, the first major update for RubyMine this year, is now released! Check out the new features below and give it a try. Don't forget to share your feedback!


Docker support

RubyMine 2017.1 brings full support for Docker! Download the Docker integration plugin right from the IDE, choose a remote Docker SDK, and enjoy working with your Docker projects like you do with local ones. Take advantage of code analysis, completion, and other smart features available in RubyMine.

RVM Gemsets

Create gemsets quickly

Create RVM gemsets from the New Project wizard. When you create a new project, the IDE will automatically suggest a similarly-named gemset and will use your project gems within this gemset. In this way, RubyMine helps you keep gems for your projects separately, preventing each of your projects from possible damage.

Alternatively, RVM gemsets can be also created in the Ruby SDK and Gems dialog.

RuboCop support

Starting with this version RubyMine supports RuboCop, the well-known static code analyzer for Ruby. The IDE runs cops in the background, and displays RuboCop offenses the same way as it does RubyMine inspections.

Test generation for Rails entities

We have added an ability to create tests for Rails controllers, models, helpers, and mailers from the Go to test action. So if you have a Rails entity without a related test, RubyMine will suggest to install the testing framework (currently works with RSpec and Test::Unit) and generate the test. You can also roll back changes if something goes wrong.

Puppet module generation

Puppet modules can be now generated quickly right from the New Project wizard. The IDE automatically detects the gems needed for Puppet and then suggests installing the missing ones. If you are already working on an existing project in RubyMine, you can also create a new Puppet module in a second from the context menu.

As for other improvements, RubyMine now can install dependencies based on .fixtures.yml.

Puppet project structure

The IDE finds all modules and/or environments in the project and updates the project structure with one click from the context menu. Open your Puppet project, Install dependencies through context menu, and enjoy working with your modules with all their dependencies accounted for.

New code style options

Code style configuration for JavaScript and TypeScript is now a lot more flexible. You can configure the use of semicolons to terminate statements, trailing commas, quotes, and wrappings for ternary operators and variable declarations with a single var.

Vue.js support

Vue.js support is now available in RubyMine through the official JetBrains plugin (Settings | Plugins | Browse repositories). Enjoy coding assistance for Vue template language and the language of your choice in the script and style blocks of a .vue file. The IDE automatically completes Vue components and adds the required imports for them.

Auto import for React components

Select a React component defined in your application in the completion popup – and the IDE will add an import for it automatically. RubyMine will also suggest a fix in case you forget to import React.

Integration with Jest

Thanks to the WebStorm team, you can now run Jest tests in RubyMine, see test results in a handy treeview, easily navigate to the test source from there, and also debug Jest tests.

See other new features coming from WebStorm.

Version control

Search & display options

The Log viewer now supports regex and case-sensitive commit message search.

Now you can control how much information the Log viewer displays. For example, you can disable Show Tag Names to make the view more compact, or enable Compact Reference View to see only the first branch name and hide the others.

Also, if you are working with big projects with tons of commits, you will be glad to know that the search in Git Log has become significantly faster.

Other improvements:

  • Parameter hints for Ruby. Find more on the blog.
  • Updated structure view of markdown files. Find more on the blog.
  • New Find in Path dialog shows search results instantly. Find more on the blog.
  • New Ruby Class dialog now allows to create classes nested in the right modules. Find more on the blog.
  • Rollbacks for generated Rails entities. Find more on the blog.
  • Cucumber 3 support.
  • Customizable colors for RegExp syntax highlighting.
  • Support for Emoji characters in the editor.
2016.3 (Nov 30)


Attach to local process

RubyMine's debugger is now capable of attaching to local Ruby processes started without debugger gems loaded on startup, whether they are being run from the IDE, a terminal or a custom pipeline. It automatically detects the Ruby version and gemset used to run the script, installs the needed gems and attaches to that process, stopping at your breakpoints.

Remote Ruby

Faster gem downloading

Downloading remote interpreter gems could take a very long time to get everything needed. With RubyMine 2016.3 it is now ~80 times faster! Thanks to the integration with rsync that made it possible.

Smarter code completion

Code completion is now aware of the code element structure for all the main syntax elements: case, class, define, function, if, node, and unless.

Data type code completion works inside lists of parameters for classes, functions and resource types.

RubyMine now supports defining Puppet functions that are also available in code completion.

Better navigation and refactoring

Go to Declaration, Find Usages, and the Rename refactoring are now aware of local and global scopes, which helps them work better for facts, functions, resource types and parameters.

Rename now works in-place, without any additional dialogs.

Comprehensive support for MiniTest::Spec

With 2016.3 RubyMine starts distinguishing MiniTest from RSpec and Test::Unit, allowing you to launch MiniTest::Spec directly from your specs.

Just make sure to require 'minitest/reporters', and include RubyMineReporter in your array_spec.rb file, to take full advantage of this light and elegant spec-style testing.

User Interface

New gem management UI

Gemsets are the convenient way to deal with different gem environments for your apps. RubyMine has supported both RVM and rbenv gemsets for a while, but now with the new Ruby version and gem management UI, you can manage gems in a more straightforward way.

New initial configuration dialog

When running for the first time, RubyMine now shows a nice dialog where you can choose your preferred color scheme and shortcut scheme, as well as enable or disable plugins as needed.

Flat icons

We've reworked the icons to achieve a flatter design. While it may look unusual at first, we believe the new icons feel sharper and less noisy.



Now, when you set JavaScript version to Flow, the IDE reports problems in the files annotated with // @flow on the fly.

Make sure you've specified the Flow installation path by going to Settings | Languages & Frameworks | JavaScript | Flow.

ECMAScript 6

Convert var to const/let – now the IDE reports all var declarations and helps replace them with let or const declarations, depending on value semantics.

Replace require() with import – for all require() calls, the IDE now provides a quick-fix that replaces them within import statements.

We've added better support for destructuring assignments. You can now easily jump to the definition from the destructuring assignment and see quick documentation and parameter info when using a function.

The Find Usages and Show Usages actions have been extended to support default-exported functions and classes.


When you rename a method that overrides or implements another method, the IDE now offers to rename the base method too. If you choose to rename the current method only, the IDE makes sure to rename all methods that override the current one.

Also, we've added a new inspection that warns you when an import statement can be shortened, and provides a quick-fix to do that.

Version Сontrol

Git & Mercurial Log improvements

Search speed has improved dramatically, particularly for the Text, Author and Path filters.

The UI is now much clearer, with more space and more readable commit messages and branch labels.


More efficient conflict resolution

Now, the IDE is capable of resolving simple conflicts automatically. When such a resolution is possible, the IDE shows a Resolve icon on the left side of the editor. Click the icon to have the conflict resolved by the IDE. To undo, press Ctrl+Z.

We've also added full syntax highlighting for non-local revisions in the Diff and Merge dialogs.

Finally, we’ve added line markers to the Merge dialog to indicate actual changes to the base revision.

Changes management

When deleting a local branch, you get a notification that lets you quickly undo it or delete the tracked remote branch as well.

Now you can undo your last committed change (that you haven't yet pushed) in one click via the Log's context menu.

The Commit Changes dialog allows you to sign-off your commit. This may be a requirement for getting patches into some projects (including the Linux kernel).

Managing Git remotes

We’ve added a way to manage Git remotes via VCS | Git | Remotes. Now you can add, edit and remove remotes for every repo in the project. Note that remotes may also be added in the Push dialog.

Database Tools

Data editing

Now you can edit multiple similar cells at once. Select several cells and start typing the value. If you need a cell editor (e.g. a Data Chooser), press Enter.

Changes made in the Table Editor are now stored locally and submitted in bulk viaCtrl+Enter.

More intelligent coding assistance

RubyMine 2016.3 brings more accurate code completion. When using JOIN USING for Postgres, it offers only the field names common for both tables. Also, the INSERT statement completion offers not only the list of all fields, but also the list of fields which have no default values.

IDE will also warn you if a variable or parameter is not used within its scope, or if there is a mismatching number of columns in queries used in set operators (UNION, INTERSECT and EXCEPT).

Now, when you access a schema or database not introspected by the IDE, RubyMine will provide a quick-fix for that.

Utilities & drivers

We've integrated the IDE with the mysqldump and pg_dump utilities.

Now the IDE helps you manage the version of the datasource driver and update it if needed. If you want to use a particular version of the driver, choose it in the driver's settings. Also, you can uncheck Use provided driver and use only files added to the Additional list.

Other improvements:

  • Improved Rails Project Tool Window interface: Mailers and their views are treated the same way as controllers.
  • Support for file renaming through Right click | Refactor | Rename, without search for usages.
  • Support for React Native.
2016.2 Jul 21


Frozen objects inspection

Since String literals are going to be immutable in Ruby 3 and Ruby 2.3 has already added a new Frozen String Literal Pragma (# frozen_string_literal: true), we’ve added a new code inspection (Settings | Editor | Inspections | Ruby | Frozen object modification) that now highlights immutable strings as well as any other frozen objects when modified.

Rbenv gemsets

RubyMine has supported rbenv gemsets since version 8. Thanks to your feedback, we go on polishing this feature to make gemset management smoother. This version brings a new inspection with a quick-fix option (Alt+Enter) available for .rbenv-gemsets and .ruby-gemset files with — any nonexistent gemset is highlighted and can be created on the fly.


Language injection

If you use YAML to store code fragments – HTML, JavaScript, SQL or others – you’ll be glad to have a new and long-awaited language injection option (Alt+Enter) in your files. It makes possible language-specific code highlighting, completion, formatting, and more.

Testing with RSpec

New refactoring for let statements

Using let statement in RSpec tests is considered to be a good practice. The IDE now encourages you to use it with the new refactoring – you can extract a code fragment into a new let statement (Refactor | Extract | RSpect 'let'), and be sure the refactoring is safe and duplicate code fragments are replaced correctly.

Capybara support

Capybara is pretty standard for RSpec acceptance tests nowadays. With RubyMine 2016.2 you can run and debug not only whole feature specs, but single scenarios as well. The IDE behaves the same for both acceptance tests and your model and controller tests.

User Interface

Fonts with ligatures

We've added support for monospace font ligatures. To enable ligatures, go to Settings | Editor | Colors & Fonts | Font, choose a font that supports ligatures, e.g. FiraCode, Hasklig, Monoid or PragmataPro and select Enable font ligatures option.

Background images

Also, we’ve added a new action called Set Background Image. Give your IDE a custom look by choosing a background image for the editor and the IDE frame.

The action is available via Find Action and, for a selected image file, via the context menu for the Project tool window and Image Editor.

Inspection Results tool window

The Inspection Results tool window has been redesigned for better ergonomics: now the code location for each problem is displayed, along with controls to apply a quick-fix or suppress the inspection.


We've reworked the way RubyMine displays notifications to make them even friendlier: the popups are now displayed in the right-hand bottom corner (next to the Event Log tool window icon), more compact, and grouped by the subsystem they came from.


ECMAScript 6

The IDE now helps convert callback functions to arrow functions when you click Alt+Enter on the function keyword. Also, it can convert arrow functions to shorthand arrow functions.

Postfix completion

In addition to the .var postfix template, added earlier, now you can use .let and .const templates. As you might guess, when you press Tab these expand into declarations with let and const keywords.


RubyMine can now provide code completion and resolve for component properties defined using propTypes. For React events the IDE will automatically add {} instead of "". Non-DOM attributes are no longer marked as unresolved, and similarly, component lifecycle methods are not marked as unused anymore.


We’ve added a collection of Live Templates for Angular. To use a template, type its abbreviation in the editor and then press Tab to expand it. Press Tab again to jump to the next edit location in the template.

Also, the Project Wizard now supports Angular CLI.

Npm, Grunt and Gulp

Now you can specify any Grunt, gulp or npm task as a Before launch task in a Run/Debug configuration.

HTML code style

Configure whether you want the IDE to add single, double or no quotes at all when autocompleting attributes in HTML and JSX.


The update brings support for TypeScript 2.0 features: optional class members, readonly property, never type, this function type, global module export declaration, resolve for type declarations in @types folder, path mappings based module resolution, and more. Also, try smarter support for enums.

Version Control


The Log viewer for Git and Mercurial continues getting better: it now loads in the background; when you select several commits, you see all commit details; and Ctrl+L can be used for navigating to the Filter field.


Working with VCS patches has never been easier. Copy the patch to the clipboard, go to RubyMine – and the IDE will immediately suggest to apply it! Alternatively, just drag the patch file into the IDE, or use the Apply Patch action in the VCS menu.

Database Tools

A new dialog helps you to import CSV and TSV files to the database.

Now you can dump multiple tables and even the entire schema, which means that any data (not only result-sets) can be exported to CSV, JSON or a list of INSERT/UPDATE statements.

Language injections let you treat string literals as live code written in other languages (like XML, JSON, any SQL dialect or regular expressions).

Table Editor adds actions for resizing columns as well as completion for values in a column.

Other improvements:

  • Markdown plugin is now bundled with RubyMine.
  • A small enhancement for those who use many languages, IntelliJ-based IDEs including RubyMine now understand what you mean, even if you forgot to switch the language of input.
  • You can now drag images, JavaScript or CSS files into the HTML file in the editor to generate src, script or link tags for them.
  • When using React with TypeScript, components are now automatically imported.
  • We've added support for case-only renames in Git for Windows and macOS.
  • The Commit dialog shows unversioned files so you don’t forget to commit something important.
