Free Plan

Step 3: License Activation​

Next, you need to activate your license after installing the executable and the IDE extension.

This process needs to be done only once per device.

Activating the License​

Use the following command in your terminal to activate the license:

dcm activate --license-key=YOUR_KEY

Alternatively, you can activate the license through the IDE extension by using the DCM: Activate license key command.

info

License activation uses the device ID, so attempts to activate a license multiple times on the same device won't reduce the activation count.

To check the active license type, use:

dcm license

Deactivating the Device​

If you need to deactivate the current device, simply uninstall the tool or activate another key.

Step 4: Integration​

Enabling DCM Rules​

With the Free plan, you can manually configure individual lint rules in your analysis_options.yaml file.

Browse the list of available rules for the Free plan and add the ones you want to enable:

analysis_options.yaml
dcm:
  rules:
    - avoid-dynamic
    - avoid-unused-parameters
    - prefer-conditional-expressions
tip

Start with a few rules and gradually add more as you become comfortable with DCM.

Enabling DCM Metrics​

DCM provides code metrics to help you measure and maintain code quality. To enable metrics in your project, add the following configuration to your analysis_options.yaml file:

analysis_options.yaml
dcm:
  metrics:
    cyclomatic-complexity: 20
    number-of-parameters: 4
    maximum-nesting-level: 5
tip

For a complete list of available metrics and detailed configuration options, refer to the Metrics documentation.
