Re: [cdt-dev] Language settings provider question

[Andrew Gvozdev <angvoz.dev@xxxxxxxxx>]

Hi Sergey,

The way you create the project does not use metadata from your org.eclipse.cdt.managedbuilder.core.buildDefinitions extension. If you look at how standard CDT New Project Wizard does it, it is more involved, see STDWizardHandler.setProjectDescription(...).

Caroline has already mentioned that you need to assign providers to your configuration before calling Manager.setProjectDescription(project, projectDescription);. From your description it is unclear if you do that.

Another issue is that you should obtain provider with call LanguageSettingsManager.getExtensionProviderCopy(id, true) rather than invoke constructor directly to avoid discrepancies.

Thanks,

Andrew

Hi Andrew,

I'm having difficulties with getting CConfigurationDescription to recognize my provider.

In plugin.xml I have:

  <extension

        point="org.eclipse.cdt.core.LanguageSettingsProvider">

     <provider

           class="org.eclipse.cdt.core.language.settings.providers.LanguageSettingsGenericProvider"

           id="myLanguageSettingsProvider"

           name="My C/C++ Settings"

           prefer-non-shared="true">

        <language-scope id="org.eclipse.cdt.core.gcc"/>

        <language-scope id="org.eclipse.cdt.core.g++"/>

     </provider>

  </extension>

  <extension

        point="org.eclipse.cdt.managedbuilder.core.buildDefinitions">

     <projectType

           buildArtefactType="org.eclipse.cdt.build.core.buildArtefactType.exe"

           id="myProjectType"

           isAbstract="false"

           isTest="false"

           name="My C++ Project">

       <configuration

             buildArtefactType="org.eclipse.cdt.build.core.buildArtefactType.exe"

             id="myConfiguration"

             languageSettingProviders="myLanguageSettingsProvider"

             name="My Configuration">

          ...

       </configuration>

     </projectType>

  </extension>

I create the project using the following code sequence:

CCorePlugin cPlugin = CCorePlugin.getDefault();

ICProjectDescriptionManager Manager = cPlugin.getProjectDescriptionManager();

ICProjectDescription projectDescription = Manager.createProjectDescription(project, false);

ICConfigurationDescription baseConfiguration =

cPlugin.getPreferenceConfiguration(ManagedBuildManager.CFG_DATA_PROVIDER_ID);

ICConfigurationDescription configDescription =

    projectDescription.createConfiguration("myConfiguration", "My Configuration", baseConfiguration);

Manager.setProjectDescription(project, projectDescription);

cPlugin.createCDTProject(project.getDescription(), project, null);

At this point ((ILanguageSettingsProvidersKeeper) configDescription).getLanguageSettingProviders() returns two providers: [id=org.eclipse.cdt.ui.UserLanguageSettingsProvider, name=CDT User Setting Entries, id=org.eclipse.cdt.managedbuilder.core.MBSLanguageSettingsProvider, name=CDT Managed Build Setting Entries]

My provider is not returned because LSPs are copied from baseConfiguration without looking at my configuration specification.

If I set the provider explicitly by

ILanguageSettingsProvider languageSettingProvider = new LanguageSettingsGenericProvider();

languageSettingProvider.configureProvider("myLanguageSettingsProvider", "My Provider",

    Collections.singletonList("org.eclipse.cdt.core.g++"), null, null);

((ILanguageSettingsProvidersKeeper) configDescription).setLanguageSettingProviders(

    Collections.<ILanguageSettingsProvider>singletonList(languageSettingProvider));

my provider gets returned by ((ILanguageSettingsProvidersKeeper) configDescription).getLanguageSettingProviders() but still appears unchecked in Preprocessor Include Paths, Macros, etc. > Providers and is called "My C/C++ Settings" rather than "My Provider".

What am I doing wrong?
