readdirs({

    ext: ['.js'],               // scan only .js files

    on: {
        // gets executed when path of file or folder obtained
        path: function(scope) {
            console.log(scope.$path);         // print full path to file or folder
            console.log(scope.$file);         // print file or folder name
            console.log(scope.$dir);          // print directory name witch contains file or directory
        },

        // methods line and eof share same scope
        // gets executed on every line
        line: function(scope) {
            console.log(scope.$line.text);    // print content of current line
            console.log(scope.$line.index);   // print index of current line
            scope.foo = 'bar';                // set value of foo in file scope
        },
        //gets executed at the end of file
        eof: function(scope) {
            console.log(scope.$file.lines);   // print array of file lines
            console.log(scope.$file.path);    // print file path
            console.log(scope.foo);           // print value of foo
        }
    }
