Subject: [cocci] How do I disable formatting for the "+"-side of a rule?
Date: Thu, 14 Jul 2022 11:31:09 +0200 [thread overview]
Message-ID: <220714.86bkts2fz9.gmgdl@evledraar.gmail.com> (raw)
How do I stop coccinelle from turning my "{ 0 };\n" into
"{\n\t\t0\n\t};\n"?
I haven't been able to find in the docs how to disable formatting on the
"+"-side of a rule. I have a rule like:
@@
type T;
identifier I;
@@
- T I;
+ T I = { 0 };
... when != \( I \| &I \)
- memset(&I, 0, ...);
Which produces the expected results as far as the patch is concerned:
diff -u -p a/builtin/for-each-ref.c b/builtin/for-each-ref.c
--- a/builtin/for-each-ref.c
+++ b/builtin/for-each-ref.c

format.format = "%(objectname) %(objecttype)\t%(refname)";
But I'd like for that to be e.g.:
struct ref_array array = { 0 };
Which is a common idiom both in this codebase (git) and elsewhere.
Usually I can find an answer in one of the coccinelle.git's *.cocci
files, the man page, or the grammar PDF, but in this case I've come up
blank...
