 Frequently Asked Questions (based on RubyMine's feedback)

1. Ruby SDK configuring. Can’t set Ruby SDK to the project:
  • remove all SDK from the RubySDK and Gems list.
  • close the project, close RubyMine.
  • reopen RubyMine, wait until all SDK will be configured.
  • open the project and select once again the needed SDK in the Settings | Ruby SDK and Gems, Apply changes, try to reproduce the problem.

If the problem will be reproducible, send us idea.log (Help | Show in Finder) to rubymine-feedback@jetbrains.com.

2. How to disable auto-save:

There is no way to switch it off. The option 'Save file on frame deactivation' in the 'Settings | Appearance&Behavior | System Settings' provides ability to make sure that a frame really will be saved, but frame will be still saved if the option is unchecked.

Disabling auto-save feature discussion: http://devnet.jetbrains.com/message/5469330

We don't support any 'on-save' actions due to the way the IDE saves changes - actually it reserves the right to save any of your files literally whenever it wishes(smile) You don't have any guarantees on when RubyMine flushes document data displayed in the editor to file system. E.g. it is allowed to do that while the document is being edited - automatic code formatting would be rather annoying then.

We have a feature request for 'on save' actions - http://youtrack.jetbrains.com/issue/IDEABKL-6722, please feel free to vote for it.
