RubyMine

New Features

New features in RubyMine 4

Be faster and more productive

• Performance - more actions operate asynchronously - for example the 'inspect code' function is up to 4x faster.
• Native gems code insight - auto-completion and code navigation when working with gems that have native components.
• Go to class by full class name - any class can now be found by its full name to help you with navigation through classes.
• Show inherited, types hierarchy - new options on the Structure and Hierarchy views allow for seeing subtypes and inherited methods.

Easier to use

• Streamlined UI - significantly reworked to be more compact, modern and comfortable on all supported platforms. Reorganised main menu, new look for navigation bar, updated editor tabs, etc.
• VCS support improvements - new stack trace highlighting, a git log graph, improved GitHub integration and image diff.
• Event log view - new 'Event Log' view/tool-window is a single place to see all IDE notifications and take action where needed.
• Class dependency diagram - shows relationships between any classes and modules in UML notation.

More code checks

• Ruby code inspection - new code inspections include checking whether if statements have an else statement, check if boolean expression contains primitive parts, check if class variable is defined, check that cyclomatic complexity of method/blocks is below the threshold etc. New 'quick-fix' intention actions are available for some inspections for instant resolution of problems.
• Code refactoring - new inline method refactoring for substituting method invocation with method code and new support for code fragment unwrapping actions for removing if/unless/while statements without removing a block of code.
• Testing and debugging - support for Minitest 2.10 and RSpec 2.8 along with updates to both the Ruby debugger and the Javascript debugger.

Support for the latest technologies

• Ruby on Rails 3.2 - all new features coming in Ruby on Rails 3.2 are supported in the IDE.
• Phusion Passenger - can be chosen as a running server in run/debug configuration.
• HTML code insight in HAML - the full HTML code insight is now available in HAML files.
• CoffeeScript - compile CoffeeScript files from within the IDE.
• SCSS/LESS support - SCSS 3.1 and LESS support.
