RubyMine 2018.1 Released: Improved Performance, Run Anything, Postfix Completion, and More

Hi everyone,

RubyMine 2018.1 (181.3204.562), the first major release of the year, is now available. Learn about all the new features on our What’s new page, or you can read a brief summary below:

Faster and smarter IDE

  • The redesigned core static analysis engine improves the performance of the IDE. In particular, code autocompletion suggestions, code inspection (Code | Inspect Code), and other features related to code analysis now respond better and complete faster. More.
  • Improved Code Insight for block variables: a block passed as a parameter is now properly resolved from the receiver block’s body. More.

Run anything

  • The new Run anything action (Double Ctrl) provides a unified way to instantly run rake tasks, rails s, or basically any script or console command. More.
  • Press Shift while using the Run anything action, and it will switch to the Debug anything mode, allowing you to run debug configurations.

Postfix code completion

  • The newly added postfix code completion lets you transform an existing expression without the need to move your caret about in the code making it possible to easily reverse, alter, or supplement statements. More.

Inline diagrams in Markdown

  • Markdown preview now renders inline diagrams! Insert puml before your diagram code in an .md file and RubyMine will properly identify the syntax and display the diagram in the preview pane. More.


  • The debugger now provides a more user-friendly way to set up exception breakpoints which will suspend execution when a certain type of exception is raised.
  • If you don’t want the debugger to stop at every exception raised, hit the plus button and choose which types of exceptions should be triggered. More.


  • TypeScript improvements. The new version supports the latest TypeScript features, improves the Implement Members action, and adds a new Surround with type guard quick-fix for unresolved properties.
  • Vue improvements. Create new Vue components from existing ones: select the part of the template you want to reuse and use Refactor | Extract or press Alt-Enter and select Extract Vue Component.
  • CSS improvements. Cmd/Ctrl-click on the class name in HTML can now navigate not only to its declaration in the compiled CSS file linked to the HTML file, but also to the Sass, SCSS, or Less source.

More JavaScript improvements available in RubyMine 2018.1

Version Control

  • The new release features partial Git commits, which allow you to include code chunks into a commit using the check-boxes, and associate the code chunks with different changelists. More.
  • Three new actions were added to make it easier to use the rebasing procedure from the IDE: Abort Rebase, Continue Rebase and Skip Commit. More.

Other improvements:

  • New Open in terminal action. More.
  • Navigate through identifier occurrences. More.
  • Comment out HTML and Ruby in .html.erb. More.
  • The navigation bar is now enabled by default. More.
  • IDE Settings Sync plugin. More.
  • By default RubyMine now completes current statements on pressing Enter.
  • Improved documentation UI.

    Good news! But the diagram rendering doesn’t seem to be working even with simple statements.

      Actually, it does render

      class Example



      But not

      Bob->Alice : hello

      Which is an example taken directly from PULM’s website.

        Hi Wilson!

        You’re quite right, there’s a known regression that prevents rendering diagrams with special symbols. This issue is marked as “critical”, and should be fixed in the next EAP build (2018.1.2 EAP), which should be out by the end of the week (or at the beginning of the next one in worst case scenario). Sorry for the trouble, and thank you for the report!

        Here’s a link to the issue https://youtrack.jetbrains.com/issue/RUBY-21345

    Wish you would post an update here for every point release of RubyMine, maybe also with a link to the release notes. Doesn’t have to be wordy, just that a release has happened.

      Dave, thank you for the comment! I sometimes do skip posts for minor releases when there are only bug-fixes, but I’ll get back to posting them always since it’s required. Thanks!
