is it possible by using uncrustify to transform this:
int a, b, c, d=0;
to this :
int a;
int b;
int c;
int d=0;
Thanx
No, this is not one of the options.
Such a thing would be more of a refactoring, than a simple tweak to spacing (which is mostly what this tool does).
There's no open feature request for this at present, either; feel free to create one.
