Please describe how to change the program code to get the following result:

int main() {
    float fooooo;
    int i = static_cast<int>          (fooooo)      ;
    return 0;
}

for the origin test.cpp:

int main() {

    float fooooo;

    int i = (int)          fooooo      ;

    return 0;

}

Вместо строки:

rewriter.ReplaceText(rPloc, 1, ">(");

сделать строку

rewriter.ReplaceText(rPloc, 1, ">");

далее найти subexpr, найти его начало (первый токен) и в полученное расположение вставить "(", то есть выполнить команду:

rewriter.InsertText(cStyleCExpr->getSubExprAsWritten()->getBeginLoc(), "(");

rewriter.InsertTextAfterToken(endLoc, ")");
}
}
private:
Rewriter& rewriter;
};
