Hello, 

I am new to coccinelle and am interested in creating a patch which can define functions based on the function pointers 
available in a struct declaration. Since the names of the pointers don't exactly match the 
function definitions I want, I used a python script to modify the names. Below is my script: 

@m_rule@ 
field list f_list; 
identifier I; 
@@ 
struct I { 
f_list 
}; 

@script:python p_rule@ 
nf << m_rule.f_list; 
n_list; 
@@ 
new_nf = [] 
for f in nf: 
parts = f.split("(") 
r_type = parts[0] 
if '*' in r_type: 
r_type=r_type.strip() 
else: 
r_type = r_type.lstrip() 
f_name = parts[1].split(")")[0].replace("*", "").strip() 
params = parts[2].split(")")[0] 
new_nf.append(r_type + "pv_" + f_name + "(" + params + ")") 
new_nf.append(r_type + "hvm_" + f_name + "(" + params + ")") 


Please how can I write a new rule that defines several lines of function definitions from 
the p_rule new_nf list available in my python structure? 

I tried adding the list in a plus(+) entry but that does not work. 


Thank you in advance for your help.
