Question

我正在尝试找一些资源/教程来帮助我创建一个coccinelle脚本来查找结构声明并将它们从有序变为无序。

在我们的代码库中，我们使用了几百个结构。有人在定义的中间添加了一个成员，现在我需要更新数百个声明。默认值为0是好的，所以如果我将所有声明从顺序切换到无序，一切都很好，以及下一次更改的未来证明。

例如：

struct some_struct {
   int blah;
   int blah2;
}

// code is like this now.
struct some_struct ex1 = {
   0,
   1,
};

// Need script to change to this
struct some_struct ex2 = {
   .blah1 = 0,
   .blah2 = 1
}

有人能指出我正确的方向吗？

您也可以尝试邮件列表提问。这样的事情可能有用：

@@
constant C1, C2;
identifier i;
@@
struct some_struct i = {
+       .blah1 =
        C1,
+       .blah2 =
        C2,
};
