I suggest to take another look at presented implementation details.

I limited my suggestion intentionally.

Such a function call is using more parameters. Would you get into
the mood then to specify additional metavariables in SmPL script variants?

I hope that more useful data processing for format strings will become
supported by the semantic patch language.
Yesterday an information was given that another functionality is also
work in progress.

I find such information interesting and promising.

This observation can be fine.
How often do you fiddle with source code transformations around
format strings?


> I think that if Julia Lawall don't know, No one in the world knows.

Such an impression can occur. - But I would like to point further
possibilities out for desired knowledge distribution.

* Would you like to contact any more related developers?

* How do you think about to improve your own expertise
  (around the discussed free software) in any ways?

Regards,
Markus
