I added two issues in github requesting new features. 

The first one is to refactor vgp to use universal ctags to parse the source function from the source file. This would simplify the vgp source code and expand the supported source languages significantly.

The second one is to support Valgrind's xml output. This could simplify the parsing a bit. But, more likely it could future proof vgp. It's less likely that Valgrind will change it's xml output formatting.
