Re: [cdt-dev] How to open a file at a particular function

["Mariot Chauvin" <mariot.chauvin@xxxxxxxxx>]

Hi Derek,

Below you will find some code to find a method name in project files. I am not a CDT expert, so maybe it's not the best way to do it.

Regards,

Mariot

*****************************************************

public class MyVisitor extends ASTVisitor {

    {
        shouldVisitDeclarations = true;
    }
    
    public static final String LINE_NUMBER = "org.yourcompany.line_number
"; //$NON-NLS-1$
    public static final String FILE = "org.yourcompany.file"; //$NON-NLS-1$
    public static final String FUNCTION = "org.yourcompany.function"; //$NON-NLS-1$
    
    
    private ArrayList result = new ArrayList();
    private String input;

    public ArrayList getResult() {
        return result;
    }
    

    public setInput(String input) {
        this.input
 = input;
    }

    
    public int visit(IASTDeclaration decl) {
        
        try {
                        
            if (decl instanceof IASTFunctionDefinition) {
                
                String function_signature = 
decl.getRawSignature();

                //check if the input is in  the function_signature
                if (function_signature.indexOf(input) > 0) {
                    //save the needed informations
                    Map b = new HashMap ();
                    b.put(MyVisitor.LINE_NUMBER,String.valueOf(decl.getFileLocation().getStartingLineNumber()));
                    b.put(MyVisitor.FILE,decl.getContainingFilename
());
                    b.put(MyVisitor.FUNCTION,((IASTFunctionDefinition) decl).getDeclarator().getRawSignature());
                    this.result.add(b);
                }
            }
            return PROCESS_CONTINUE;
        } catch (Throwable e) {
            return PROCESS_ABORT;
        }
    };
    
}

and in an another class :

private void visitFolders(ICContainer folders[], ASTVisitor astVisitor) throws CoreException {

        for (int i=0; i<folders.length; i++) {

            ITranslationUnit files[] = folders[i].getTranslationUnits();

            for (int j=0;j<files.length;j++) {
                IASTTranslationUnit ast = files[j].getAST();
                if (ast !=null) ast.accept(astVisitor);
            }

            this.visitFolders(folders[i].getCContainers(), astVisitor);
        }
    }

....

MyVisitor myVisitor = new MyVisitor();
myVisitor.set("the method name you search"); 

this.visitFolders(project.getSourceRoots(), myVisitor);
// then you get the results
...

Hi,

Given a function or method name (as a String), how can I locate the file it is
defined in and open that file at the function definition? Any pointers to code,
snippets or docs would be very useful.

Thanks
