Run/Debug Configuration: Ruby
Use this dialog to define run/debug configuration for a Ruby script.
Before you start working with Ruby, make sure that Ruby plugin is installed and enabled. Press Ctrl+Alt+S, go to Plugins and inspect the Installed tab to ensure the plugin is 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:
|Name||In this field, specify the name of the current run/debug configuration.|
|Ruby script||Specify the fully qualified path to a Ruby script to be executed, or click , and select the desired Ruby script in the dialog that opens.|
|Script arguments||Type the optional arguments to be passed to the Ruby script.|
|Working directory||Specify the current directory to be used by the running task. By default, the project directory is used as a working directory.|
Specify the list of environment variables as the name-value pairs, separated with semi-colons. Alternatively, click to create variables and specify their values in the Environment Variables dialog.
Specify the arguments to be passed to the Ruby interpreter.
Note that when JRuby is used as the project interpreter, the list of Ruby arguments can include Nailgun argument
Classpath property is added to Nailgun settings.
|Ruby SDK||Specify the desired Ruby interpreter. You can opt to choose the project default Ruby SDK, or select a different one from the list of configured Ruby SDKs.|
|Run the script in the context of the bundle||If this checkbox is selected, the script will be executed as specified in the Gemfile.|
Code Coverage tab
Use this tab to configure code coverage monitoring options.
|Choose coverage runner|
Select the desired code coverage runner.
|Sampling||Select this option to measure code coverage with minimal slow-down.|
|Tracing||Select this option to collect accurate branch coverage. This mode is available for the IntelliJ IDEA code coverage runner only.|
|Track per test coverage|
Select this checkbox to detect lines covered by one test and all tests covering line. If this checkbox is selected, becomes available on the toolbar of the coverage statistic popup.
Refer to the section Set coverage in run configurations.
|Packages and classes to record code coverage data||Click and select Add Class or Add Package to specify classes and packages to be measured. You can also remove classes and packages from the list by selecting them in the list and clicking the button.|
|Enable coverage in test folders.||If this checkbox is selected, the folders marked as test are included in the code coverage analysis.|
|Run new instance of the Nailgun server, or use already started one|
This checkbox is only available for JRuby used as the project interpreter.
When a run/debug configuration, with this checkbox selected, is launched, IntelliJ IDEA analyzes the running processes, and does one of the following, depending on the presence of the running Nailgun server:
If this checkbox is not selected, then the script is launched in a usual way, without Nailgun.
|Is Active||Select checkboxes in this column to have the log entries displayed in the corresponding tabs in the Run tool window or Debug tool window.|
|Log File Entry|
The read-only fields in this column list the log files to show. The list can contain:
|Skip Content||Select this checkbox to have the previous content of the selected log skipped.|
|Save console output to file||Select this checkbox to save the console output to the specified location. Type the path manually, or click the browse button and point to the desired location in the dialog that opens.|
|Show console when a message is printed to standard output stream||Select this checkbox to activate the output console and bring it forward if an associated process writes to Standard.out.|
|Show console when a message is printed to standard error stream||Select this checkbox to activate the output console and bring it forward if an associated process writes to Standard.err.|
|Click this button to open the Edit Log Files Aliases dialog where you can select a new log entry and specify an alias for it.|
|Click this button to edit the properties of the selected log file entry in the Edit Log Files Aliases dialog.|
|Click this button to remove the selected log entry from the list.|
When you edit a run configuration (but not a run configuration template), you can specify the following options:
Specify a name for the run/debug configuration to quickly identify it when editing or running the configuration, for example, from the Run popup Alt+Shift+F10.
Allow parallel run
Select to allow running multiple instances of this run configuration in parallel.
By default, it is disabled, and when you start this configuration while another instance is still running, IntelliJ IDEA suggests to stop the running instance and start another one. This is helpful when a run/debug configuration consumes a lot of resources and there is no good reason to run multiple instances.
Store as project file
Save the file with the run configuration settings to share it with other team members. The default location is .idea/runConfigurations. However, if you do not want to share the .idea directory, you can save the configuration to any other directory within the project.
By default, it is disabled, and IntelliJ IDEA stores run configuration settings in .idea/workspace.xml.
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.
|Alt+Insert||Create a run/debug configuration.|
|Alt+Delete||Delete the selected run/debug configuration. Note that you cannot delete default configurations.|
|Ctrl+D||Create a copy of the selected run/debug configuration. Note that you create copies of default configurations.|
|The button is displayed only when you select a temporary configuration. Click this button to save a temporary configuration as permanent.|
|View and edit the template (that is, the default run/debug configuration settings). The templates are displayed under the Templates node and used for newly created configurations.|
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.
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, click , and specify the folder name. 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 or and buttons.
To remove grouping, select a folder and click .
|Click this button to sort configurations in the alphabetical order.|
In this area, you can specify tasks to be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list.
Click this icon to add one of the following available tasks:
|Alt+Delete||Click this icon to remove the selected task from the list.|
|Enter||Click this icon to edit the selected task. Make the necessary changes in the dialog that opens.|
|/||Alt+Up/ Alt+Down||Click these icons to move the selected task one line up or down in the list. The tasks are performed in the order that they appear in the list.|
|Show this page||Select this checkbox to show the run/debug configuration settings prior to actually starting the run/debug configuration.|
|Activate tool window|
Otherwise, if the checkbox is cleared, the tool window is hidden. However, when the configuration is running, you can open the corresponding tool window for it yourself by pressing Alt+4 or Alt+5.
