Hello,
The coding style specification for C programs in GNOME contains also
the following information.
https://developer.gnome.org/programming-guidelines/stable/c-coding-style.html.en#whitespace
“…
Always put a space before an opening parenthesis but never after:
…”
How good can the semantic patch language support such a requirement
(also for function declarations and corresponding calls) directly?
See also a related feature request once more:
Make change influence configurable for coding style rules

Regards,
Markus

If you want to check for such properties, you can use position variables.
If you want to ensure that your generated code has such properties, you
can use the argument --smpl-spacing. If you want something more, you are
welcome to implement it. We only focus on the coding style of the Linux
kernel.

It is nice that code additions can be influenced by such a parameter.

I imagine that adjustments for matched metavariables might need
further development considerations.
Would there be a need to reformat any expression code (for example)?
Which software places would become interesting for extensions of
source code layout algorithms?

How are the chances that interests will grow also for source files
of GNOME components?

Markus

Can there be a need for a related run time parameter for the handling
of line breaks?

Markus
