Hi,

I'd like to convert a bunch of gboolean decleration to stdbool in our 
ConnMan code base. I am a noob with coccinelle. I have partial success 
so far but I do not thing I am doing the right thing. So any advice is 
welcome :)


This here is my current coccinelle script for converting gboolean used 
as stack variable. I have also one for structs, which gave my good 
results. Another one is needed then for the function arguments. But 
let's first have a look on this part.

@r1@
position p;
typedef gboolean;
identifier func,x;
@@
func(...) {
<...
	gboolean@p x;
...>
}

@r2@
position r1.p;
typedef bool;
@@
- gboolean at p
+ bool

@r3@
identifier r1.x;
@@
(
- x = FALSE
+ x = false
|
- x = TRUE
+ x = true
)

int main(int argc, char *argv[])
{
	gboolean b = TRUE;

	return 0;
}

results in

int main(int argc, char *argv[])
{
-       gboolean b = TRUE;
+       bool b = true;

         return 0;
}

which is what I wanted. Now the problem is that I really have no clue to 
mach on things like

int main(int argc, char *argv[])
{
	gboolean b = TRUE, c = FALSE;

	return 0;
}

Any idea?

cheers,
daniel
