Re: [cdt-dev] Codan launch modes

Hi,

It seems I used correctly the API and XML plug-in extensions.

How can I fill a bug?

It's the first time I've to report a bug for Eclipse/CDT/Codan.

Le 17/03/2019 à 21:09, Aubin Mahé a écrit :
Even when I deactivate "RUN_AS_YOU_TYPE" and "RUN_ON_FILE_OPEN", parsing still occurs on file open.

Not sure about the first problem, but regarding the second: I'm pretty sure "as you type" is a superset of "on file open", i.e. it doesn't actually wait for you to type. (Internally it's implemented using the platform's "reconciler" mechanism.)

Hope that helps,
Nate

Marc-Andre, your suggestion works well, internal states seems to be good
- traces are the same than mine - but the behaviour and the UI panels
are wrong, as shown in my first post.

First and second problems remains.

Hi!

I don’t remember exactly how this works, but here is an example from ProblemBindingChecker.java:

       @Override
       public void initPreferences(IProblemWorkingCopy problem) {
               super.initPreferences(problem);
               // This checker should not run on full or incremental build
getLaunchModePreference(problem).enableInLaunchModes(CheckerLaunchMode.RUN_AS_YOU_TYPE,
CheckerLaunchMode.RUN_ON_DEMAND);
       }

Maybe you could give this a try?

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?
