Subject: [cocci] spatch adds zero or two lines after if statement
Date: Fri, 14 Oct 2022 14:03:39 +0200	[thread overview]
Message-ID: <7bda3ec2-1335-4451-dc59-b70faa216750@intel.com> (raw)

Adding 'if' statement to the code does not add empty line after it, as 
expected, but if I explicitly add empty line spatch adds two lines, and 
this is unexpected. How can I convince spatch to add exactly one line?

Following script:
@@
@@
+ if (1)
+ printf("a\n");
return 0;

@@
@@
+ if (1)
+ printf("b\n");
+
return 1;

##### EOF
used on file:
int a()
{
return 0;
}

int b()
{
return 1;
}
##### EOF
produces:
@@ -1,9 +1,15 @@
int a()
{
+ if (1)
+ printf("a\n");
return 0;
}

int b()
{
+ if (1)
+ printf("b\n");
+
+
return 0;
}
##### EOF

Regards
Andrzej
