I guess that you know something also for this programming language
according to the program option “--c++”.

I am looking for further evolution around this software area.

How would we like to handle corresponding development challenges?

@display@
expression X;
identifier I;
@@
*auto I = X(...);


elfring@Sonne:~/Projekte/Coccinelle/Probe> spatch --parse-cocci 
show_variable_definition_with_auto1.cocci
init_defs_builtins: /usr/local/bin/../lib/coccinelle/standard.h
minus: parse error:
  File "show_variable_definition_with_auto1.cocci", line 5, column 6, charpos = 
47
  around = 'I',
  whole content = *auto I = X(...);


Can such a source code search approach make sense also according to
the rules of the C programming language?

Regards,
Markus
