I would expect general support for such a task by the semantic patch language.

I find that this is a succinct description for your source code transformation goal.


The usage of the other SmPL code seems to indicate that your understanding
grew for the application of previously mentioned syntax elements in significant ways.
We will probably be more curious then how the data processing for SmPL ellipses
(triple dots) within format strings can become better together with a different
selection of metavariables for possible SmPL disjunctions.

Regards,
Markus
