[cdt-dev] Antwort: Re: API to add Settings provider to Preprocessor Incl

[Jens Frieben <jens.frieben@xxxxxxxxxxxxxxxxx>]

I have the same issue. Solved it to some
degree with the following code.
The provider is added and moved to the
top (first position of the array). Only this way, the provided symbols
can override existing ones
The snipplet is executed in a SetCommandOperation
provided by the org.eclipse.cdt.managedbuilder.ui.newWizardPages extension
point (see operationClass).

HOWEVER: Sometimes, the provider gets
deselected again. I am not sure why and when. I am still searching for
a solution.
I hope this will help you
Best regards

Jens


// Manually add the language provider
--- it is not activated and set to the top position despite the correct
entry in the toolchain ....
ICProjectDescriptionManager manager
= CoreModel.getDefault().getProjectDescriptionManager();
ICProjectDescription prjDescriptionWritable
= manager.getProjectDescription(project, true);
ICConfigurationDescription cfgDescriptionWritable
= prjDescriptionWritable.getActiveConfiguration();
String[] oldProviderIDs = ((ILanguageSettingsProvidersKeeper)
cfgDescriptionWritable).getDefaultLanguageSettingsProvidersIds();
List<ILanguageSettingsProvider>
provider = ((ILanguageSettingsProvidersKeeper) cfgDescriptionWritable).getLanguageSettingProviders();

String[] newProvidersId = Arrays.copyOf(oldProviderIDs,oldProviderIDs.length
+ 1);
// add the new provider in front
newProvidersId[0] = PxCToolchainBuiltinSpecsDetector.PROVIDER_ID;
for (int i = 0; i < oldProviderIDs.length;
i++) {
        newProvidersId[i+1]
= oldProviderIDs[i];
}

((ILanguageSettingsProvidersKeeper)
cfgDescriptionWritable).setDefaultLanguageSettingsProvidersIds(newProvidersId);
List<ILanguageSettingsProvider>
providers = LanguageSettingsManager.createLanguageSettingsProviders(newProvidersId);
((ILanguageSettingsProvidersKeeper)
cfgDescriptionWritable).setLanguageSettingProviders(providers);
((ILanguageSettingsProvidersKeeper)
cfgDescriptionWritable).getDefaultLanguageSettingsProvidersIds();
((ILanguageSettingsProvidersKeeper)
cfgDescriptionWritable).getLanguageSettingProviders();
try {
        manager.setProjectDescription(project,
prjDescriptionWritable);
} catch (CoreException e) {
        e.printStackTrace();
}

ManagedBuildManager.saveBuildInfo(project,
true);

Maybe you can look at the Cross GCC toolchain
as a simple example? If I look quickly at the plugin.xml, it looks like
there's a "languageSettingsProviders" field in the toolchain
definition.

Subject: [cdt-dev] API to add Settings provider to Preprocessor Include
path Entries 
 
Hello
I'm trying to set by default my own LanguageSettingsProvider.
I've created a ext point, I can see it in the prefs. When I check the preprocessorInclude
path properties of my project, my provider is available as provider, but
not checked. 
Is there any API to check it by default ?

I remark also, when I check manually my provider to have
is in the Settings Entries, A new file appears in the root of the project
in .settings/language.settings.xml which contains the provider.
Thanks for your help

Regards
Vincent
