Open, close, and move projects

Last modified: 27 March 2023

Open and reopen projects

Open a project

  • Click New Project on the Welcome screen.

  • From the main menu, select File and click Open or Recent Projects if you have worked with the project lately.

    Alternatively, you can open projects from the command line.

Open projects in a new or the same window

By default, when you launch the second of any subsequent project, the IDE asks you how you want to open it: in a new window or in the same window. You can configure the default behavior for such cases in the settings:

  1. In the Settings dialog (CtrlAlt0S), select Appearance & Behavior | System Settings.

  2. In the Project section, select the necessary Open project in option:

    • New window: open every project in a separate window.

    • Current window: close the current project and open the new one in the same window.

    • Ask: show a dialog with actions to choose from.

    the System Settings page in Settings

  3. Apply the changes and close the dialog.

Always reopen projects

If you quit the IDE having multiple opened projects, they all will be reopened the next time you launch RubyMine. If you don't want to automatically reopen your projects, you can change this behavior in the settings:

  1. In the Settings dialog (CtrlAlt0S), select Appearance & Behavior | System Settings.

  2. In the Project section, clear the Reopen projects on startup checkbox.

  3. Apply the changes and close the dialog.

Open multiple projects in one window

RubyMine allows you to work with multiple projects simultaneously. You can open your projects either in separate windows or in one window. When opening projects in several windows, they are independent and don't share any information. Opening multiple projects in one window might be useful when one project uses the information from another.

Attach a project to the main one

  1. Having one project already opened in RubyMine, select File | Open and choose the project you want to attach.

  2. In the Open Project dialog, click Attach.

    the Open project dialog

    RubyMine will show both projects in the Project tool window.

Open projects with multiple Gemfiles

RubyMine automatically detects directories with Gemfiles and suggests processing them as Ruby projects.

gemfile warning

  • Click Configure, select the projects to be created for each Gemfile found and click OK.

    gemfiles without projects

    Select Don't ask again to disable automatic Gemfile detection.

    If necessary, you can enable the Create projects for new Gemfiles option to process folders with new Gemfiles as Ruby projects automatically. You can also manage auto-creation of Ruby projects using the Auto-create Ruby projects for Gemfiles action.

  • To create a project later manually, right-click a corresponding folder in the Project tool window and select Mark Directory as | Ruby Project Root. Note that this command is only available for directories containing Gemfiles.

Detach a project from a shared window

  • To delete the attached project from the Project view, right-click it and select Remove from Project View Delete.

Merge project windows (macOS)

On macOS, you can merge all opened project windows into one, turning them into tabs.

  1. Make sure that there are several RubyMine projects opened in separate windows.

  2. From the main menu, select Window | Merge All Project Windows.

    Drag a project's tab to work with the project in a separate window again.

If you work with multiple projects, it's likely that you have a long list of recent projects on the Welcome screen. RubyMine provides several options that can help navigate this list in a more convenient way.

You can use the search bar to search for projects, join several recent projects in a group, or set a custom icon for each project.

Group projects

Groups make navigation simpler and help you logically organize your recent projects.

After that, hover the mouse pointer over the group and use the App general gear plain icon to show the menu from which you can open all projects in the group at once by clicking All Projects in Group. You can also ungroup the projects, move them to another group, and remove them from the list of recent projects at once.

Change the project icon

For each project, you can configure a custom icon so that you can quickly find the necessary project on the Welcome screen. Your custom icon should have the SVG format.

Switch between projects

If you have several opened projects at the same time, you can switch between them using the following options:

  • Switch to the next project window: CtrlAlt0] (Window | Next Project Window)

  • Switch to the previous project window: CtrlAlt0[ (Window | Previous Project Window)

Alternatively, open the Window menu and select the project to which you want to switch.

Change project location

Move a project to another location

  1. In the Project tool window Alt01, right-click the root directory of your project and select Refactor | Move directory (F6).

  2. In the dialog that opens, specify a new location for the project and click Refactor.

    Moving a project to another location

Change the default location for projects

  1. In the Settings dialog (CtrlAlt0S), select Appearance & Behavior | System Settings.

  2. In the Default project directory field, specify the path to the folder in which you want to store your projects.

  3. Apply the changes and close the dialog.

    Changing the default location for projects

Close projects

If you need to close only one project, you can either close the project window or select File | Close Project from the main menu.

If you work with multiple projects, use the following actions to close many projects at once:

Close all projects

  • From the main menu, select File | Close All Projects.

    This action closes all projects that are currently opened in RubyMine.

Close all but the current project

  • From the main menu, select File | Close Other Projects.

    This action closes all opened projects except the current one.
