Subject: [RFC] Improved handling of member access operators with SmPL expression variables
Date: Sun, 30 Aug 2026 10:15:17 +0200	[thread overview]
Message-ID: <fc7bba15-5116-4467-bce1-be8ff3859184@web.de> (raw)

Hello,

I pointed out that some data processing can be achieved by the means of
the semantic patch language.

SmPL script example:
@display2@
identifier an_item, a_field;
@@
(
*an_item.a_field
|
*an_item->a_field
)


Extend support for data processing with member identifications

https://github.com/coccinelle/coccinelle/issues/226#issuecomment-699787269


Another SmPL script example:
@my_test@
expression hint;
@@
*hint->hint


Questionable test result (also according to the software combination “Coccinelle 1.3.2”):
Markus_Elfring@Sonne:…/Projekte/Coccinelle/Probe> spatch --parse-cocci show_expression_for_same_member_name.cocci
…
minus: parse error: 
  File "show_expression_for_same_member_name.cocci", line 4, column 7, charpos = 37
  around = 'hint',
  whole content = *hint->hint


How will development interests evolve to improve affected software components?
