ROOT's binaries understand a mixture of short and long arguments. The parsing is done in C++, with ad hoc C++ code. We would like to switch to a C++ command line argument library.
This would imply implementing ROOT's options (e.g. in
rootcling_impl.cxx) using that library.
- ROOT's command line arguments are parsed with a C++ library; we can combine arguments:
root -lbq tutorials/hsimple.C
Basic C++ knowledge; there is nothing ROOT specific.
