hey IOhannes,
Why generate verbosity levels on the fly? So far we've been using
the
syslog levels, I think we should stick with that and use that
throughout.
so far nobody has been using "syslog" levels. i don't know when they
entered the game.
however, the main reason to "generate on the fly" was, that i prefer
to
say "i want loglevels up to 7" rather than i want loglevels "1" and
"2"
and "3" and "4" and "5" and "6" and "7".
at a central point in the code i define a "maxverbosity". the code
then
generates menuitems for each loglevel.
in the past there was a "maxverbosity"; and then there was a menu,
where
you could chose totally unrelated loglevels; code relying on
maxverbosity (e.g. colouring code), would work only by chance with the
loglevels selected by the menu.
i prefer to change values in a single place.
and i prefer to let computers do what they are better at than me (e.g.
counting)
if "syslog" for you means you have loglevels 0..7, then go ahead and
set
maxverbosity to "7" and that's it.
if instead of system administration, you want to go with many
programming frameworks (log4j and it's various clones like log4c,
log4perl, log4..), set the maxverbosity to "5".
i agree that we should eventually agree on a common maxverbosity.
but this should still be managed centrally, and not cluttered around
the
code.
This sounds a lot more complicated without much real gain. How about
just emulating syslog? Its a tried true way to do it, and it is
already widely understood and documented.
- messages post at log levels 0-7
- the menu item sets the "all levels up to X"
- the messages are tagged with level to be optionally colorized
