A better IDE

Better performance

Better performance

This release has significant performance improvements that the team have been working on the whole year. To put it in a nutshell, the IDE has become faster, which is especially easy to see when RubyMine works at full blast. Go to Code | Inspect Code to run it for your whole project and see for yourself.

Better resolution

Navigate to Declaration, one of RubyMine's most beloved and used features, has become even better! We've eliminated bottlenecks that might have prevented you from jumping to external keywords like callbacks and responders. Update now to see the rest of the resolution improvements no other editor can offer.

Better Code Insight

Better Code Insight

Code Insight features have been significantly reworked. In particular, RubyMine has become much better at mapping declared method arguments with the given ones.

Not only that, but some built-in Inspections and Intentions have been fixed, making the IDE even more robust.

Run v2017.3 and inspect any particular errors, and fix them in bulk across the whole project.

                                  for complex projects

Better support for complex projects

Another highlight of the new RubyMine improvements is that now there is better support for applications with nested projects, like Rails Event Store. For these types of applications, the IDE detects the projects located within the app and their own Gemfiles and allows you to install and resolve the required dependencies.

Please note, your feedback is indispensable for us to further improve the applications with complex architecture.


Windows subsystem for Linux

Linux subsystem for Windows

RubyMine 2017.3 features Windows Bash Support! We encourage our Windows users to try out WSL in RubyMine to get rid of any painful configs on Windows, and exploit the full power of the IDE.

Follow this tutorial to install WSL, and then add it as a remote SDK in RubyMine (Preferences / Settings | Languages & Frameworks | Ruby SDK and Gems | New remote).


Extract method to

Extract methods to private and protected

Extracting methods with RubyMine is a piece of cake, but now it's even sweeter. With this release you can extract methods (Refactor | Extract) to a private, protected, or even public section if you want.

Rubocop autocorrect

Autocorrect by offense class or cop department

Starting from now, RubyMine's RuboCop in-editor autocorrections outperform any other alternative. With a simple Alt+Enter you can autocorrect the whole file or fix a specific cop department or an offense class.

Together with RubyMine's respect for your rubocop.yml configs, this makes the IDE your personal code style censor.

Code style

Method indentation and spaces around operators

You asked us to add an ability to indent private and protected methods, and now you got it! Find these options in Editor | Code style | Ruby and reformat your methods' indentation the way you want (Code | Reformat code).

In addition, you can now choose which operators should be wrapped with space, and which kept as is. The formatter will follow your choice.

                            Name Hints

Parameter name hints improved

Parameter name hints have become much cannier: you can now configure them to be displayed for literals only, as well as turn them off for excessive cases, e.g. when the given arguments are self-explanatory.

Moreover, the new Show implicit param grouping option will wrap all the optional values into the improvised array for better visibility.

Find the new settings in Preferences / Settings | Editor | General | Appearance.

Embedded Puppet template syntax

DevOps is the future and Puppet doesn't rest on its laurels – nor does RubyMine! The new release brings support for the EPP template syntax.

Not only does the IDE now recognize the original EPP syntax, but it also correctly autocompletes and navigates from templates to manifests and back.

On top of that, Rename Refactoring works for variables and parameters, and you can Find Usages of your template files in seconds.


Trace to_s eval
                                               with the debugger

Trace to_s evaluation

The new Trace to_s evaluation option detects costly operations and throws a timeout message, saving you time during the debugging session.

Find it in Preferences / Settings | Build, Execution, Deployment | Debugger and check it out for yourself.

REST Client

New REST Client

New REST client

This release introduces a new way to test APIs from the IDE. Now you can write HTTP requests in a .http file and then quickly run them with the icons on the editor gutter.


Better code completion,
documentation, CSS, and Vue.js

Code completion and parameter info for the standard JavaScript objects, methods, and Web APIs have all been improved, thanks to the TypeScript declaration files. Also, the documentation available via F1 now includes a brief description of the methods.

The Vue.js support features, completion and navigation to the definition, now work for Vue props, properties in the data object, computed properties, and methods. You will also find a collection of code snippets for Vue!

Code completion for CSS properties and values has become more precise, with the previously missing completion suggestions added for values with transform, transition, and pointer-events properties.

Version Control

Interactively Rebase from Here, workspaces for branches, and more

The Log viewer now offers an Interactively Rebase from Here action, which can help you pick, edit, skip, squash, reword, and fixup commits through a convenient UI dialog.

Now when you switch between branches, the IDE preserves your workspace: the opened files, the current run configuration, and the breakpoints.

Finally, RubyMine now shows the files which were changed by merge commits, even if they differ from one parent. Not only that, but the IDE also displays a 3-panel Diff for the merge conflicts.

Database tools

Managing schema, SQL generator, grouping data sources, and more

The Schemas node in the database tree has been replaced with a hover option, which shows the number of schemas currently displayed in the tree. Click on it to add or hide schemas.

You can now use the SQL generator to generate DDL scripts with options. Go to Context xmenu | SQL Scripts | SQL Generator and get the generated DDL of any type of object (table, schema, procedure) or even several objects simultaneously.

Also, we’ve added the following SSH improvements:

  • Reading OpenSSH config files (~/.ssh/config и /etc/ssh/ssh_config).
  • Showing dialogue for a One Time Password.
  • Using Ssh-agent and Pageant authentication.

Finally, the long-awaited ability to group data sources is available in this release.

JavaScript & TypeScript

The new Move Symbol refactoring allows you to safely move classes, global functions or variables in ES6 modules from one JavaScript or TypeScript file to another.

Coding assistance in JavaScript files now respects webpack module resolution. When you’re using a complex webpack configuration with aliases and multiple modules, the IDE will properly resolve paths in import statements and suggest symbols to import.

Code style

The new Arrangement and Blank lines code style options allow you to configure how different blocks of code such as fields and methods are ordered and separated. Call the Rearrange Code action or use it together with Reformat Code to make code more readable and consistent.

Also, you can now import some of the ESLint code style rules to the IDE’s JavaScript code style settings.

Improved Sass SCSS

Improved SASS and SCSS

For Sass and SCSS selectors created using &, you can now use code completion in HTML files and navigate to the definition.

For the nested selector, you can quickly jump to the definition with Cmd-click / Ctrl+click.

Version Control

Revert and reword commits

The Git Log features two new handy actions: Revert and Reword.

Revert allows you to remove any registered changes by adding a new commit. Read more

Reword provides a convenient way to reword your local commits. Read more

Format commit message

Format commit messages

The settings for the Commit dialog have been reworked and moved to the Commit Dialog page (Preferences / Settings | Version Control | Commit Dialog).

The new settings let you customize the rules applied to commit messages: a blank line between the subject and the body, and the maximum length. Also, now the IDE offers a quick fix and the Reformat action inside Commit Message.

Improved Shelf


The Shelf tab has been reworked for better performance and ergonomics. Now it has a Preview panel and provides a new action to compare the “shelved” version of a file with its local version.

User Interface

Gutter in Find in Path

Find in Path

The Preview panel in Find in Path now has a Gutter – a left-side pane like the one in the editor – with line numbers, navigation icons, and local change markers.

Search results from the same lines are now merged together.

Other improvements:

  • Database improvements.
  • Debugging with Docker.
  • Added RuboCop inspections and quick-fixes to scratch files.
  • Fixed significant performance issues.
  • Added an ability to compare items with different deployed versions.
  • Patches can now be created to clipboard.
2017.1 (Mar 22)


Docker support

RubyMine 2017.1 brings full support for Docker!

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.

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.
