Description / Overview

Choose one of (or both) solution:

1. enable the possibility to force the log parameter using environment variable, e.g.::ab:

CAMITK_LOG_LEVEL=WARNING CAMITK_LOG_TO_STDOUT=FALSE CAMITK_LOG_TO_FILE=TRUE CAMITK_LOG_FILE_DIRECTORY=/tmp camitk-imp"

to force camitk-imp running with these log parameters instead of those defined in source or settings Caveat: you need to modify the environment variable and access to it from the code. Not really a problem, but can be tricky for people who don't understand it properly, modify their global environment (e.g. in ~/.bashrc) and then forgot they had define these things.

2. manage a --debug=[options] argument from the command line execution for all CamiTK application with different options:

log level:
le (error)
lw (warning)
li (info)
lt (trace)

d (display debug)

s (display time stamp)

log message:
me
mw
mi
mt
p

Hints

• Use Qt to read the environment variables and modify the application properties accordingly
• Add a flag to camitk-imp and camitk-config arguments

Acceptance tests

• there are more tests of the testlogger class that shows it work
• the Log System document is updated accordingly
