So, if I don't have any typedef in the code and I just want to replace
the name of the field of a struct?
for example to modify this function:
f() {
struct my_struct *m;
struct my_struct x;
...
m->len = 10; // this should become m->length = 10;
...
fill(x.buf); // this should become fill(x.addr);
}
I'm trying to use
@@
identifier a;
@@
struct my_struct a.
- len
+ length
Which gives syntax error. I need somehow to tell spatch that "identifier
a" has type "struct my_struct" but "type struct osmo_gsn_address;" seems
to be invalid syntax.

I don't understand what you are trying to do here. typedef new_address;
is find for indicating that new_address is a typedef. Ie you have
somewhere said:
typedef ... new_address;
new_address a; will then match a declaration where the type of the
declared variable is new_address. But I don't understand - a.len;.
First, this is only going to match a statement that comes right after the
variable declaration. Second, a.len; is a very strange statement, because
it doesn't do anything.
Maybe you want:
@@
typedef new_address;
new_address a;
@@
- a.len
+ a.length
That is, a should be a metavariable representing an expression of the
given type, and then you want to replace a len field by length.
You could also write the change as:
a.
-len
+length
