Subject: [Cocci] Replacing a struct member with a function call
Date: Sun, 14 Mar 2021 00:55:06 +0000	[thread overview]
Message-ID: <CAOhcEPbTH-oTTn1OUkgoYf2GaBKaCYjwpWuhrdNRkNQ0uZ_r4A@mail.gmail.com> (raw)

Hello all,

I'm wanting to replace a struct member with a function call across the
code base I'm working on.

For example, I currently have the following struct definition (simplified):

struct monitor {
    struct {
        int width;
        int height
    } virtual;
};

Across my code base, I typically have the following:

struct monitor *m;
int f = m->virtual.width;

I have a need to remove `m->virtual.width` with a function call, hence
the example above after the modified code would look something like:

struct monitor *m;
int f = get_monitor_width();

I've tried the following smPL code without any success.  Could someone
point me in the right direction?  TIA!

@@
type M;
@@
- m->virtual.width;
+ get_monitor_width();
