How to Import Previous Darcula Color Scheme in RubyMine

Hey all,

This post explains why we decided to update the Darcula color scheme in RubyMine 2018.3, and shows you how to quickly rollback to the previous version of Darcula if you don’t like the new one.

Why new Darcula

RubyMine 2018.3 comes with a new, much nicer, Darcula color scheme. In the new version, we updated colors for most of the Ruby/Rails elements to make your code look less noisy. For example, we got rid of the glaring red color used for Ruby classes and require calls, reworked the strings that were too bright and bold, and fixed some other aesthetics to make it look that little bit prettier:

RubyMine provides you with a set of intention actions that can help you to quickly fix code smells, convert statements for better code style, add strings to locale dictionaries, use language injections, and do other handy things simply by pressing Alt+Enter. Let’s review all the basic and new intention actions added in RubyMine 2018.3 EAP.

RubyMine 2018.2.3 Is Available

Hi everyone,

RubyMine 2018.2.3 (build 182.4323.73) is now available. This minor release features an ability to explicitly run scripts with bundle exec. Previously RubyMine used RUBYOPT options to achieve the same result, which caused confusion and issues in specific cases (see RUBY-11434 & RUBY-22247).

To explicitly run scripts with bundle exec, go to Help | Find Action | Experimental features, and check ruby.force.explicit.bundle.exec:


Note that this option will be enabled by default starting with v2018.3 (to be released in November 2018).

Some other annoying issues were also fixed in this build:

  • GEM_HOME/GEM_PATH not set” warning [RUBY-22254]
  • Inability to read the $GEM_HOME environment variable [RUBY-22237]

Download RubyMine 2018.2.3

See the release notes for the full list of improvements and please report any issues you encounter.
