[cdt-dev] Codan launch modes

[Aubin Mahé <aubin.mahe@xxxxxxxxxx>]

Hello,

I've created a checker plug-in based on CodAn and try to set up launch 
modes.

Checker inherits 
org.eclipse.cdt.codan.core.cxx.model.AbstractIndexAstChecker and 
overrides initPreferences because I haven't found any extension point 
dedicated to this usage.

  @Override
  public void initPreferences( IProblemWorkingCopy problem ) {
      final LaunchModeProblemPreference lmpp =
          getLaunchModePreference( problem );
      lmpp.addLaunchMode( CheckerLaunchMode.RUN_ON_FULL_BUILD,
          Boolean.FALSE );
      lmpp.addLaunchMode( CheckerLaunchMode.RUN_ON_INC_BUILD ,
          Boolean.FALSE );
      lmpp.addLaunchMode( CheckerLaunchMode.RUN_ON_DEMAND    ,
          Boolean.TRUE  );
      lmpp.addLaunchMode( CheckerLaunchMode.RUN_ON_FILE_OPEN ,
          Boolean.FALSE );
      lmpp.addLaunchMode( CheckerLaunchMode.RUN_AS_YOU_TYPE  ,
          Boolean.TRUE  );
      lmpp.addLaunchMode( CheckerLaunchMode.RUN_ON_FILE_SAVE ,
          Boolean.FALSE );
      System.out.println( problem.getName() + ": "
          + problem.getPreference());
  }

At runtime, console shows success of initialization:

    ...
    RAF-LNG-020: 
[org.eclipse.cdt.codan.core.param.FileScopeProblemPreference@4eddffcf, 
[(boolean)RUN_ON_FULL_BUILD=false, (boolean)RUN_ON_INC_BUILD=false, 
(boolean)RUN_ON_DEMAND=true, (boolean)RUN_ON_FILE_OPEN=false, 
(boolean)RUN_AS_YOU_TYPE=true, (boolean)RUN_ON_FILE_SAVE=false], 
(string)suppression_comment]
    RAF-LNG-030: 
[org.eclipse.cdt.codan.core.param.FileScopeProblemPreference@25264061, 
[(boolean)RUN_ON_FULL_BUILD=false, (boolean)RUN_ON_INC_BUILD=false, 
(boolean)RUN_ON_DEMAND=true, (boolean)RUN_ON_FILE_OPEN=false, 
(boolean)RUN_AS_YOU_TYPE=true, (boolean)RUN_ON_FILE_SAVE=false], 
(string)suppression_comment]
    ...

First problem:

  Window -> Preferences -> C/C++ -> Code Analysis -> Customize Selected 
(button) -> Launching (tab) shows

    [X] Run as you type
    [ ] Run on file open
    [ ] Run as file save
    [X] Run on incremental build
    [X] Run on full build
    [X] Run on demand

Second problem:

    When a file is opened my checker is called and report errors.

How can I really tune launch modes?
