Re: [cdt-dev] Standalone indexer works for C not C++

[Nicolas Anquetil <anquetil.nicolas@xxxxxxxxx>]

I got these from PTP-RDT:

    private static final Map<String,IPDOMLinkageFactory> linkageFactoryMap = new HashMap<String,IPDOMLinkageFactory>() {{
        put(ILinkage.C_LINKAGE_NAME, new PDOMCLinkageFactory());
        put(ILinkage.CPP_LINKAGE_NAME, new PDOMCPPLinkageFactory());
    }};

    private static final ILanguageMapper languageMapper = new ILanguageMapper(){
        public ILanguage getLanguage(String file) {
            if(file.endsWith(".c"))
                return GCCLanguage.getDefault();
            else if ( file.endsWith(".cpp") || file.endsWith(".C") || file.endsWith(".c++") )
                return GPPLanguage.getDefault();
            return null;
        }
    };


Well, I am not peculiar on the way to use the standalone indexer.
I arrived at this solution by copy-and-paste and trial-and-error.
I don't pretend I am understanding everything it does.

If you can share a better (in the sense that does work) way to do it, I would gladly (and humbly) accept it.

What language is returned by the language mapper?

We don't use the standalone indexer in quite the same way you are using it, so there may be a subtle difference somewhere in some of the code you don't show.

Hi guys,

You might recall that I asked how to parse and index C projects with
CDT standalone.

Well I succeeded thanks to your help.

However, I also want the same thing for C++ and strangely enough,
things appear to behave differently :-(

Would you have a suggestion?

Following is an excerpt of the code:
---
List<String> tus = // all C (resp. C++) files in the project
directory. this includes .h
IIndexLocationConverter locationConverter = new
URILocationConverter(projectDir.toURI());  // note
URILocationConverter is based on URIRelativeLocationConverter
macroDefinitions = Collections.emptyMap();
scannerInfo = new ScannerInfo(macroDefinitions, includePaths);
indexer = new StandaloneFastIndexer(new File("xyz"),
locationConverter, linkageFactoryMap, scannerInfo,
/*FileEncodingRegistry*/null, mapper, LOG);
indexer.rebuild(tus, new NullProgressMonitor());
foreach C /* resp. C++ */ file
 FileContent fc = FileContent.createForExternalFileLocation(srcfile);
 IASTTranslationUnit unit =
mapper.getLanguage(srcfile).getASTTranslationUnit(fc, scannerInfo,
ExternalFilesProvider.getInstance(), indexer.getIndex(), 0, LOG);
---

The problem is that with C++ name.resolveBinding() is null in the following:
---
IASTName name = // some ASTName from the unit
indexer.getIndex().findDeclarations(name.resolveBinding())
---


With C projects it does work :-(

I understand it is a lot of uncomplete code. If you need the whole
thing I can send it.

I believe the main question is: Why is it working for C and not C++?
What is the difference?
any suggestion where I should look?

thanks

nicolas
