Run/Debug Configuration: tox

The tox run/debug configuration enables you running test with different Python versions and interpreters.

The dialog consists of the following tabs:

Configuration tab
Logs tab

Configuration tab

Item	Description
tox
Arguments	Specify the arguments that are passed to the tox.ini script. The arguments are delimited with spaces, for example, `--some-arg --foo-arg`.
Run only environment	Specify here the Python environments/interpreters, where your project will be executed. The environments are delimited with commas, for example, `py27,py34`.
Environment
Project	Click this list to select one of the projects, opened in the same JetBrains DataSpell window, where this run/debug configuration should be used. If there is only one open project, this field is not displayed.
Environment variables	This field shows the list of environment variables. If the list contains several variables, they are delimited with semicolons. To fill in the list, click the browse button, or press `Shift+Enter` and specify the desired set of environment variables in the Environment Variables dialog. To create a new variable, click , and type the desired name and value. You might want to populate the list with the variables stored as a series of records in a text file, for example: Variable1 = Value1 Variable2 = Value2 Just copy the list of variables from the text file and click Paste () in the Environmental Variables dialog. The variables will be added to the table. Click Ok to complete the task. At any time, you can select all variables in the Environment Variables dialog, click Copy , and paste them into a text file.
Python Interpreter	Select one of the pre-configured Python interpreters from the list. Note that you can select a, as well as the local one. If a remote interpreter is selected (in the %edition% edition), you have to specify path mappings in the corresponding field that appears.
Interpreter options	In this field, specify the command-line options to be passed to the interpreter. If necessary, click , and type the string in the editor.
Working directory	Specify a directory to be used by the running task. When a default run/debug configuration is created by the keyboard shortcut `Ctrl+Shift+F10`, or by choosing Run from the context menu of a script, the working directory is the one that contains the executable script. This directory may differ from the project directory. When this field is left blank, the bin directory of the JetBrains DataSpell installation will be used.
Path mappings	This field appears, if a remote interpreter has been selected in the field Python interpreter. Click the browse button to define the required mappings between the local and remote paths. In the Edit Path Mappings dialog, use / buttons to create new mappings, or delete the selected ones.
Add content roots to PYTHONPATH	Select this checkbox to add all content roots of your project to the environment variable PYTHONPATH;
Add source roots to PYTHONPATH	Select this checkbox to add all source roots of your project to the environment variable PYTHONPATH;
Docker container settings This field only appears when a Docker-based remote interpreter is selected for a project.. Speaking about the correspondence of settings with some options (`--net`, `--link`, and so on), note that these options come from Docker command line arguments. Click to open the dialog and specify the following settings:
Options	Disable networking: select this checkbox to have the networking disabled. This corresponds to `--net="none"`, which means that inside a container the external network resources are not available. Network mode: corresponds to the other values of the option `--net`. `bridge` is the default value. An IP address will be allocated for container on the bridge’s network and traffic will be routed through this bridge to the container. Containers can communicate via their IP addresses by default. To communicate by name, they must be linked. `host`: use the host's network stack inside the container. `container:<name\|id>`: use the network stack of another container, specified via its name or id. Refer to the Network settings documentation for details. Links: Use this section to link the container to be created with the other containers. This is applicable to `Network mode = bridge` and corresponds to the `--link` option. Publish all ports: Expose all container ports to the host. This corresponds to the option `--publish-all`. Port bindings: Specify the list of port bindings. Similar to using the `-p` option with `docker run`. Extra hosts: This corresponds to the `--add-host` option. Refer to the page Managing /etc/hosts for details. Volume bindings: Use this field to specify the bindings between the special folders- volumes and the folders of the computer, where the Docker daemon runs. This corresponds to the `-v` option. See Managing data in containers for details. Environment variables: Use this field to specify the list of environment variables and their values. This corresponds to the `-e` option. Refer to the page ENV (environment variables) for details. Click to expand the tables. Click , , or to make up the lists.

Logs tab

Use this tab to specify which log files generated while running or debugging should be displayed in the console, that is, on the dedicated tabs of the Run or Debug tool window.

Item	Description
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: Full paths to specific files. Aliases to substitute for full paths or patterns. These aliases are also displayed in the headers of the tabs where the corresponding log files are shown. If a log entry pattern defines more than one file, the tab header shows the name of the file instead of the log entry alias.
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.
	Click this button to edit the select log file entry. The button is available only when an entry is selected.

Common

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

Item	Description
Name	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, JetBrains DataSpell 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 JetBrains DataSpell stores run configuration settings in .idea/workspace.xml.

		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.
/	`Alt+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.
		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 .
