Hi,
Thanks a lot for your answer.
There are two things I had to change to make the example work.
First the provider class has to be an own class. I just made a copy of LanguageSettingsGenericProvider.
<extension
point="org.eclipse.cdt.core.LanguageSettingsProvider">
<provider
class="org.eclipse.cdt.example.toolchain.MyLanguageProvider"
id="org.eclipse.cdt.example.toolchain.provider1"
name="Example Provider"
prefer-non-shared="true">
<entry
kind="includePath"
name="/project/include">
</entry>
<entry
kind="macro"
name="MYMACRO"
value="3">
</entry>
</provider>
</extension>
<extension
point="org.eclipse.cdt.ui.LanguageSettingsProviderAssociation">
<id-association
id="org.eclipse.cdt.example.toolchain.provider1"
ui-edit-entries="true">
</id-association>
</extension>
Secondly the I had to use your touchProjectDes() method to make the project description dirty.
The configuration description was already writable, and I did not need a Workspace Job.
public void addEntries(IProject project) throws CoreException {
ICProjectDescription projectDescription = CoreModel.getDefault().getProjectDescription(project, true);
ICConfigurationDescription configs[] = projectDescription.getConfigurations();
ICConfigurationDescription cfgDescription = null;
for (ICConfigurationDescription config : configs) {
if (config.getId().contains("example")) {
cfgDescription = config;
break;
}
}
System.out.println("cfgDescription id: " + cfgDescription.getId());
if (cfgDescription.isReadOnly()) {
System.out.println("cfgDescription read only");
}
if (!(cfgDescription instanceof ILanguageSettingsProvidersKeeper)) {
System.out.println("no writable");
}
MyLanguageProvider provider = null;
List<ILanguageSettingsProvider> providers = ((ILanguageSettingsProvidersKeeper) cfgDescription)
.getLanguageSettingProviders();
for (ILanguageSettingsProvider p : providers) {
if (p.getId().contains("example")) {
provider = (MyLanguageProvider) p;
break;
}
}
if (provider == null)
return;
System.out.println("provider id: " + provider.getId());
List<ICLanguageSettingEntry> entries;
List<String> languageScope = new ArrayList<String>();
languageScope.add("org.eclipse.cdt.core.gcc");
// Entries from plugin.xml are added to the global workspace provider instance.
ILanguageSettingsProvider globalProvider = null;
globalProvider = LanguageSettingsManager.getWorkspaceProvider("org.eclipse.cdt.example.toolchain.provider1");
entries = globalProvider.getSettingEntries(null, null, null);
// Get existing entries from configuration provider, otherwise create new entries.
entries = provider.getSettingEntries(cfgDescription, project, "org.eclipse.cdt.core.gcc");
if (entries == null)
entries = new ArrayList<ICLanguageSettingEntry>();
// Add include path
CIncludePathEntry entry;
entry = CDataUtil.createCIncludePathEntry("/home/project/include", ICSettingEntry.NONE);
entries.add(entry);
provider.setLanguageScope(languageScope);
provider.setSettingEntries(cfgDescription, project, "org.eclipse.cdt.core.gcc", entries);
touchProjectDes(projectDescription);
CoreModel.getDefault().setProjectDescription(project, projectDescription);
}
private void touchProjectDes(ICProjectDescription desc) {
// Make sure the project description is marked as modified so that language
// settings serialization kicks in.
// We need to let the setProjectDescription do the serialization because we
// cannot do it on a writable description
// and we need a writable description because we need to call setSourceEntries!
final QualifiedName TOUCH_PROPERTY = new QualifiedName(CCorePlugin.PLUGIN_ID, "touch-project"); //$NON-NLS-1$
desc.setSessionProperty(TOUCH_PROPERTY, ""); //$NON-NLS-1$
desc.setSessionProperty(TOUCH_PROPERTY, null);
}
The entries I add in the plugin.xml are only added to the global workspace provider instance. Not to the configuration provider instance.
I see them in the GUI when I enable checkbox "Use global provider shared between projects".
And programmatically:
globalProvider = LanguageSettingsManager.getWorkspaceProvider("org.eclipse.cdt.example.toolchain.provider1");
entries = globalProvider.getSettingEntries(null, null, null);
When the checkbox in the GUI is unchecked the configuration entries are gone.

Hi Erwin!
I did go through some pains trying to add entries programatically somewhat recently.
You can see the hurdles in CompilationDatabaseParser class.
I would double check that you have a writable ICConfigurationDescription. If not, I think you have to get a writable description and set it within a WorkspaceJob. Also make sure you get the correct language settings provider from this writable description. See CompilationDatabaseParser.scheduleOnWritableCfgDescription for example.
I also remember the description was not seen as dirty just by changing language settings. I did a hack by setting a “session property” on the project description. See CompilationDatabaseParser.touchProjectDes.
I don’t really master any of these parts but maybe one of those suggestions will help you.

Hi,
When I add an editable language settings provider via the plugin.xml to a CDT plugin per configuration, the entries added in the plugin.xml are not there.
And when I add entries programmatically to the provider they are also not there.
What am I doing wrong?
I took the example from the CDT plugin developers guide and added this to the plugin.xml:
<extension
point="org.eclipse.cdt.core.LanguageSettingsProvider">
<provider
class="org.eclipse.cdt.core.language.settings.providers.LanguageSettingsGenericProvider"
id="org.eclipse.cdt.example.toolchain.provider1"
name="Example Provider"
prefer-non-shared="true">
<entry
kind="includePath"
name="org.eclipse.cdt.example.toolchain.entry2"
value="/project/include">
</entry>
</provider>
</extension>
<extension
point="org.eclipse.cdt.ui.LanguageSettingsProviderAssociation">
<id-association
id="org.eclipse.cdt.example.toolchain.provider1"
ui-edit-entries="true">
</id-association>
</extension>
<configuration
id="org.eclipse.cdt.example.toolchain.configuration1"
languageSettingsProviders="org.eclipse.cdt.example.toolchain.provider1;org.eclipse.cdt.managedbuilder.core.MBSLanguageSettingsProvider;org.eclipse.cdt.ui.UserLanguageSettingsProvider"
name="Test Release">
.....
</configuration>
Adding entries programmatically:
LanguageSettingsGenericProvider provider = null;
List<ILanguageSettingsProvider> providers = ((ILanguageSettingsProvidersKeeper) cfgDescription)
.getLanguageSettingProviders();
for (ILanguageSettingsProvider p : providers) {
if (p.getId().contains("example")) {
provider = (LanguageSettingsGenericProvider) p;
break;
}
}
System.out.println("provider id: " + provider.getId());
// Output: provider id: org.eclipse.cdt.example.toolchain.provider1
// No number suffix (?)
// Get existing entries (from plugin.xml).
List<ICLanguageSettingEntry> entries = provider.getSettingEntries(cfgDescription, project,
"org.eclipse.cdt.core.cSource");
// entries appears to be null. I would expect to see the include path from plugin.xml.
if (entries == null)
entries = new ArrayList<ICLanguageSettingEntry>();
// Add extra include path
CIncludePathEntry entry;
entry = CDataUtil.createCIncludePathEntry("/project/include/extra", ICSettingEntry.NONE);
entries.add(entry);
provider.setSettingEntries(cfgDescription, project,
"org.eclipse.cdt.core.cSource", entries);
CoreModel.getDefault().setProjectDescription(project,
projectDescription);
