[Cocci] how to ignore a list of identifiers

[Mansour Moufid]

Hi everyone,

I'm trying to add the const qualifier to variables of a certain type,
except for a few.

For example, I'd like to modify this program:

    void foo(void) {
        int a = 1;
        int b = 2;
        int c = 3;
        int d = 4;
    }

to:

    void foo(void) {
        const int a = 1;
        int b = 2;
        const int c = 3;
        int d = 4;
    }

So far I've tried this semantic patch:

    @@
    identifier x != {b, d};
    @@
    + const
      int x = ...;

This works but only if all the identifiers in the list are in the source.

If the list is {b, z} for example, it doesn't work, and spatch says:

    (ONCE) Expected tokens z b

Is there an easy way to do this?

Thanks for your time.
