Project Wizard

Working with the project wizard can be illustrated with the RedLine SmallTalk plugin

Implementing New Module Type

Additional support for specific tools and technologies is usually done via implementing some certain module type which is attached to the project. New module type should be derived from the class ModuleType.

Project Wizard

Main utilities to configure a custom project wizard can be found in the package lang-api.ide.util.projectWizard. These classes and interfaces serve the following purposes:

  • Modification of the configuration wizard view
  • Adding new steps to the wizard
  • Providing additional setting for project creation
  • Handling activities during project creation
  • Initial environment configuration

Module Type

To create a new module type and an extension

<moduleType id="MY_MODULE" implementationClass="st.redline.smalltalk.module.MyModuleType"/>

to the plugin.xml. A custom module type should extend the ModuleType generic from ModuleBuilder. The following module type implementation of a custom module type show how this instance can be registered and implemented.

Implementing Module Builder

To set up a new module environment ModuleBuilder class should be extended and registered as an extension point like the following snippet shows:

<extensions>
    <!--Place your extensions here-->
    <moduleBuilder builderClass="org.jetbrains.plugins.ruby.rails.facet.versions.MyModuleBuilder"/>
</extensions>

Functionality which is mandatory to implement consists of:

  • Setting up a root model for the new module by overriding

    public abstract void setupRootModel(ModifiableRootModel modifiableRootModel) throws ConfigurationException;
    
  • Getting a module type

    public abstract ModuleType getModuleType();
    

See JavaModuleBuilder to understand better how to implement a module builder.

If your module type is based on the java module and meant to support Java as well, extending JavaModuleBuilder is enough. No extension point needs no be registered. Refer to SmallTalk module type to see how JavaModuleBuilder can be derived.

Implementing Module Builder Listener

Module builder listener reacts on a new module creation, which could be done either as a part of the project creation process, or as adding a new module to the already existing project. To provide a certain behavior right after a module has been created, module builder should implement ModuleBuilderListener Method

public void moduleCreated(@NotNull final Module module);

executed tasks right after a module has been created, these may include configuring roots looking up for an SDK and setting it up, adding a specific facet if required and others. For more details please see the following SmallTalk custom module type implementation.

Adding New Wizard Steps

Adding new steps to the module wizard can be done by overriding the

public ModuleWizardStep[] createWizardSteps(WizardContext wizardContext, ModulesProvider modulesProvider);

method in a custom module builder. If this method returns a non-empty array of ModuleWizardStep objects, new steps will be shown in their indexing oder while creating a new module. The following implementation for the SmallTalk project type illustrates how a custom wizard step can be created. The RsModuleWizardStep class is derived from ModuleWizardStep, which has two methods to be overridden:

  • public JComponent getComponent();
    
    defines how the step will look like
  • public void updateDataModel();
    
    commits data from UI into ModuleBuilder and WizardContext

Facet

Facets in IntelliJ are the way to store multiple kinds of module-specific settings, for instance to make a language support or framework available in some given module. To understand facets better from the point of view of an end-user, please see Facet documentation section.
