Run/Debug Configuration: Ruby Remote Debug

Use this dialog box to define configuration for remote debugging of the Ruby scripts.

In this section:

Prerequisites

Before you start working with Ruby, make sure that Ruby plugin is installed and enabled.

Also make sure that the following prerequisites are met:

  • Ruby SDK is downloaded and installed on your machine.
  • The required framework SDKs are downloaded and installed on your machine.

Refer to their respective download and installation pages for details:

Information and settings

ItemDescription
NameIn this text box, specify the name of the current run/debug configuration.
Server commandUse the following command on the server side to enable remote debug:
rdebug-ide --host 0.0.0.0 --port <port number> --dispatcher-port <port number> -- $COMMAND$

This read-only field shows the command that should be entered on the server side to launch the debug server. Port and dispatcher-port numbers here are taken from the Port and Local port fields. $COMMAND$ corresponds to the name of the script to be debugged.
Remote hostSpecify URL of the host where remote debugging will take place.
Remote portSpecify the port number on the server side. Note that the number entered in this field, is automatically used in the rdebug command. As you type port number, the suggested command string changes accordingly.
Remote root folderSpecify the root directory on the server side, where the script to be debugged is located. This field defines mapping to the local root folder.
Local portSpecify the local port number. Note that the number entered in this field, is automatically used in the rdebug command. As you type the local port number, the suggested command string changes accordingly.
Local root folderSpecify the local root directory containing the script in question. Type the path, or click browseButton.png and find the desired root in the Select Path dialog box.

Common options

When you edit a run configuration (but not a run configuration template), you can specify the following options for it:

ItemDescription
Name In this text box, specify the name for the run/debug configuration. The name will help you identify the created configuration when you choose to edit it later, or when you invoke it, for example. from the Run popup (Shift+Alt+F10).
Share Select this check box to make the run/debug configuration available to other team members.

If the directory-based project format is used, the settings for a run/debug configuration are stored in a separate .xml file in the .idea\runConfigurations folder if the run/debug configuration is shared, or in the .idea\workspace.xml file otherwise.

If the file-based format is used, the settings are stored in the .ipr file for shared configurations, or in the .iws file otherwise.

Single instance only

Toolbar

The tree view of run/debug configurations has a toolbar that helps you manage configurations available in your project as well as adjust default configurations templates.

ItemShortcutDescription
icons general add svgAlt+InsertCreate a run/debug configuration.
icons general remove svgAlt+Delete Delete the selected run/debug configuration. Note that you cannot delete default configurations.
icons actions copy svg Ctrl+D Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.
icons general settings svg Edit Templates View and edit the default template for the selected run/debug configuration. The templates are used for newly created configurations.
icons actions moveUp svg/icons actions moveDown svgAlt+Up/Alt+Down

Move the selected run/debug configuration up and down in the list.

The order of configurations in the list defines the order, in which the configurations appear when you choose a run/debug configuration.

Default templates of run/debug configurations are always sorted alphabetically.

folder Move into new folder / Create new folder

You can group run/debug configurations by placing them into folders.

To create a folder, select the configurations within a category to be grouped, click folder, and specify the name for the folder. If only a category is in focus, an empty folder is created.

Then, to move a configuration into a folder, between the folders or out of a folder, use drag-and-drop or icons actions moveUp svg and icons actions moveDown svg buttons.

To remove grouping, select a folder and click icons general remove svg.

icons objectBrowser sorted svg Sort configurations Click this button to sort configurations in alphabetical order.

Templates

When you select Templates in the tree view of the run configurations, you can adjust some settings that apply for all run debug configurations.

ItemDescription
Configurations available in Run Dashboard

In this section you can create a list of run configurations available in the Run Dashboard — tool window that helps you execute and manage multiple run/debug configurations.

Note that the dashboard will only display those configuration types for which you have created one ore more configurations.
So if you add a configuration type for which no configurations exist in the project, this type will not be displayed on the dashboard until you create a configuration of this type.

Confirm rerun with process terminationThe behavior of this checkbox depends on whether the Single instance only checkbox is selected for a particular run/debug configuration.
  • If this checkbox is selected, then, in case of a single instance, launching a new process (for example, by clicking run on the main toolbar) while another process is still running, results in showing a dialog box prompting to terminate the current process before launching a new one.
  • If this checkbox is not selected (or in case of multiple instances), IntelliJ IDEA starts the new process silently.
Temporary configurations limit Specify here the maximum number of temporary configurations to be stored and shown in the Select Run/Debug Configuration drop-down list.

Before Launch options

In this area you can specify tasks that should be carried out before starting the selected run/debug configuration. The specified tasks are performed in the order they appear in the list.

ItemShortcutDescription
icons general add svgAlt+Insert Click this icon to add one of the following available tasks:
  • Run External tool — select this option to run an application which is external to IntelliJ IDEA. In the dialog that opens, select the application or applications that should be run. If the necessary application is not defined in IntelliJ IDEA yet, add its definition. For more information, see Configuring Third-Party Tools and External Tools.
  • Make — select this option to have the project or module compiled. The Make Module command will be carried out if a particular module is specified in the run/debug configuration, and the Make Project command otherwise.

    If an error occurs during the compilation, IntelliJ IDEA won't attempt to start the run/debug configuration.

  • Make, no error check — the same as the Make option but IntelliJ IDEA will try to start the run/debug configuration irrespective of the compilation result.
  • Build Artifacts — select this option to build an artifact or artifacts. In the dialog that opens, select the artifact or artifacts that should be built.
  • Run Another Configuration — select this option to execute another run/debug configuration. In the dialog that opens, select the configuration to be run.
  • Run Ant target — select this option to run an Ant target. In the dialog that opens, select the target to be run.
  • Run Grunt task — select this option to run a Grunt task. In the Grunt task dialog box that opens, specify the Gruntfile.js where the required task is defined, select the task to execute, and specify the arguments to pass to the Grunt tool.

    Specify the location of the Node.js interpreter, the parameters to pass to it, and the path to the grunt-cli package.

  • Run Gulp task — select this option to run a Gulp task. In the Gulp task dialog box that opens, specify the Gulpfile.js where the required task is defined, select the task to execute, and specify the arguments to pass to the Gulp tool.

    Specify the location of the Node.js interpreter, the parameters to pass to it, and the path to the gulp package.

  • Run Maven Goal — select this option to run a Maven goal. In the dialog that opens, select the goal to be run.
  • Run npm Script — select this option to execute an npm script. In the NPM Script dialog box that opens, specify the npm run/debug configuration settings.
  • Start React Native Bundler — - elect this option to run the bundler automatically, as part of a running or debugging session. by default, this is done through react-native start. If your application uses Expo, you need to run the development server via the start npm task. To do that, clickicons actions edit svg, then in the Configure React Native dialog, choose npm script and select start from the list.
  • Compile TypeScript — elect this option to run the built-in TypeScript compiler and thus make sure that all the changes you made to your TypeScript code are reflected in the generated JavaScript files. In the TypeScript Compile Settings dialog that opens, select or clear the Check errors checkbox to configure the behaviour of the compiler in case any errors are detected:
    • If the Check errors checkbox is selected, the compiler will show all the errors and the run configuration will not start.
    • If the Check errors checkbox is cleared, the compiler will show all the detected errors but the run configuration still will be launched.
  • Generate CoffeeScript Source Maps — select this option to generate the source maps for your CoffeeScript sources. In the dialog that opens, specify where your CoffeeScript source files are located.
  • Upload files to Remote Host — select this option to have the application files automatically uploaded to the server according to the default server access configuration.
  • Run Remote External tool — adds a remote SSH external tool.
  • Run Rake task — add a Rake task to be executed prior to running or debugging. To choose a Rake task, click the browse button browseButton, and select the desired task from the list of available tasks.

    Note that code completion is available here.
