Re: [cdt-dev] Language settings provider question

[Andrew Gvozdev <angvoz.dev@xxxxxxxxx>]

Hi Sergey,

If your entries do not change it is easier to add them directly to org.eclipse.cdt.core.LanguageSettingsProvider extension point. It is possible to add project relative paths if you flag the path as workspace path and define its name using ${ProjName} variable, for example "/${ProjName}/bar/inc" with VALUE_WORKSPACE_PATH flag.

Otherwise, assuming that you have implemented org.eclipse.cdt.core.LanguageSettingsProvider and buildDefinitions extension points, you can get providers with

((ILanguageSettingsProvidersKeeper) cfgDescription).getLanguageSettingProviders()

Then you can iterate to find your id. Note that in this case you'll be responsible to serialize the collected entries with one of serialize methods.

Thanks,

Andrew

Hi Andrew,

Thanks a lot for the suggestions. What is the right way to get an instance of LanguageSettingsGenericProvider corresponding to my LSP id and a project? I need an instance of the LSP to call setSettingEntries on it during project creation.

Hi Sergey,

First you need to implement extension point org.eclipse.cdt.core.LanguageSettingsProvider. If you need per-project (that will be per configuration) it needs to be an instance of ILanguageSettingsEditableProvider. There is a generic implementation you can use - LanguageSettingsGenericProvider.

In order to get providers created for new projects with New Project Wizard - use org.eclipse.cdt.managedbuilder.core.buildDefinitions extension point to associate the provider with your project type. Specify attribute "languageSettingsProviders" for element "configuration" or "toolchain". There is a brief description in the extension point schema which may be useful.

If you do not use buildDefinitions extension point it is possible to attach providers to configurations programmatically. Check out test cases in org.eclipse.cdt.core.tests/org.eclipse.cdt.core.language.settings.providers, for example testConfigurationDescription_ProvidersUniqueId(). I would be up to you where to call this code from.

There is one more extension point org.eclipse.cdt.ui.LanguageSettingsProviderAssociation. You can define there a custom icon, allow or disallow editing in UI and provide a custom page for editing options in Options pane.

Thanks,

Andrew

I my plugin I need to define a per-project language settings provider. Can I use LanguageSettingsSerializableProvider class directly without subclassing it? If so, what is the right way to get an instance of the provider to call LanguageSettingsSerializableProvider.setSettingEntries(ICConfigurationDescription, IResource, String, List<ICLanguageSettingEntry>) on it?
