Re: [cdt-dev] How to add Keyword to CDT Parser

Hi Anitha,

there must a detail which is incorrect.

This is my implementation:

public class IARCScannerExtensionConfiguration extends AbstractScannerExtensionConfiguration {

    private static IARCScannerExtensionConfiguration instance;
   
    public static synchronized IARCScannerExtensionConfiguration getInstance() {
        if(instance == null)
            instance = new IARCScannerExtensionConfiguration();
        return instance;
    }
   
    private IARCScannerExtensionConfiguration() {
        /*
           add part of GNU configuration
        */
        addKeyword(GCCKeywords.cp__ASM, IToken.t_asm);
        addKeyword(GCCKeywords.cp__ASM__, IToken.t_asm);
        addKeyword(GCCKeywords.cp__CONST, IToken.t_const);
        addKeyword(GCCKeywords.cp__CONST__, IToken.t_const);
        addKeyword(GCCKeywords.cp__INLINE, IToken.t_inline);
        addKeyword(GCCKeywords.cp__INLINE__, IToken.t_inline);
        addKeyword(GCCKeywords.cp__VOLATILE, IToken.t_volatile);
        addKeyword(GCCKeywords.cp__VOLATILE__, IToken.t_volatile);
        addKeyword(GCCKeywords.cp__SIGNED, IToken.t_signed);
        addKeyword(GCCKeywords.cp__SIGNED__, IToken.t_signed);
        addKeyword(GCCKeywords.cp__TYPEOF, IGCCToken.t_typeof);
        addKeyword(GCCKeywords.cp__TYPEOF__, IGCCToken.t_typeof);
        addKeyword(GCCKeywords.cpTYPEOF, IGCCToken.t_typeof );       
       
        /*
           add IAR C specific configuration
        */       
        addKeyword("__bitvar".toCharArray(), IGCCToken.tIDENTIFIER );       
       
        /*
           add general keywords configuration
        */   
        addKeyword("double".toCharArray(), IGCCToken.tIDENTIFIER );
       
        addMacro("__bitvar", "");
}

In addition find here the definition of the language:
public class IARCLanguage extends GCCLanguage {
   
    public static final String ID = "com.valeo.vws.cdt.iartoolchain.iarclanguage"; //$NON-NLS-1$

    private static IARCLanguage DEFAULT = new IARCLanguage();
   
    public static IARCLanguage getDefault() {
        return DEFAULT;
    }
   
    public String getId() {
        return ID;
    }

    @Override
    protected ISourceCodeParser createParser(IScanner scanner,
            IParserLogService log, IIndex index, boolean forCompletion,
            int options) {
        if (!(scanner instanceof IARCScanner)) {
            scanner = new IARCScanner(scanner);
        }
        return super.createParser(scanner, log, index, forCompletion, options);
    }
   
    @Override
    protected IScannerExtensionConfiguration getScannerExtensionConfiguration(IScannerInfo info) {
        return IARCScannerExtensionConfiguration.getInstance();
    }
   
    @Override
    protected ICParserExtensionConfiguration getParserExtensionConfiguration() {
        return IARCParserExtensionConfiguration.getInstance();
    }

}

Furthermore you need to map the content type to your language. I did this using the org.eclipse.cdt.core.language and org.eclipse.core.contenttype.contentTypes extension points. In addition I added a languate mapping in the project properties->C/C++ General->Language Mappings.

Hope this helps.

Regards, Sebastian
