-h option

ROOT
1

I’ve implemented a lot of options for my program using optparse, but when I call python myapplication.py -h I got the ROOT help:

Usage: python [-l] [-b] [-n] [-q] [dir] [[file:]data.root] [file1.C ... fileN.C]
Options:
  -b : run in batch mode without graphics
  -n : do not execute logon and logoff macros as specified in .rootrc
  -q : exit after processing command line macro files
  -l : do not show splash screen
 dir : if dir is a valid directory cd to it before executing

How to avoid it?

However, I tried to used same instructions but it does not work.
Attached it for you in this msg.

Please, can you clarify this issue for me?

Hi,

the mentioned two lines have to be the very first lines of access of the ROOT module. If any other variables are touched before it, TApplication will be created, which takes the CLI options.

Cheers,
Wim
