The only way to merge names is to have matched them in different branches
of a disjunction, which unfortunately is not currently possible for a function
declaration/function prototype or to match the name and store its position,
and then have another rule that uses a disjunction and the position variables
to merge the names.
I imagine that I stumble on the need to assign data from eventually two source
rules to variables with the same name.
@@
position first_match.p1;
position second_match.p2;
identifier x;
@@
(
x@p1
|
x@p2
)
I would interpret this filter pattern in the way that new values will be
assigned to the metavariables.
The grammar of the semantic patch language shows following elements where I
would like to suggest an extension.
http://coccinelle.lip6.fr/docs/main_grammar003.html
@ script:language [rulename] [depends on dep] @
...
script_metadecl ::= (id,id) << rulename_id1.id, rulename_id2.id, ...,
rulename_idN.id ;
| id << rulename_id1.id, rulename_id2.id, ...,
rulename_idN.id ;
...
Which rule should provide some data for the target metavariable?
How do you think about it?
Regards,
Markus
