Your patch built and tested without issue. I just have a few minor
comments:
Please remove all commented out debugging output code and one instance
of wxLogDebug unless you are planning to some additional debugging in
the future. In which case, use wxLogTrace.
Per section 4.2 in the coding policy[1], in source files there should be
2 blank lines between functions except when they are in the class
definition in which case there should be 1 blank line. I also saw a
couple of if{} statements with missing blank lines above.
It is no longer necessary to wrap strings with the wxT() macro when
using the wxString assignment operator.
The OUPUTFORMATTER::Print function can throw an IO_ERROR exception. If
you don't handle this, KiCad will most likely crash when it occurs. It
would be a good idea to add a try/catch block in
HYPERLYNX_EXPORTER::Run() and return false when a exception is caught.
The copyright dates in the qa files are 2018.
