Better argument parsing(30 January 2019)
Use a C++ command line argument library for defining and parsing ROOT’s options.
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
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.
