Darn - forgot reply responds to boost. So, I apologize for the stupid
The scenario we use is something akin to the following (using macros):
LOG(int level, string tag) << "whatever";
The logging (as a whole) can be enabled/disabled. When enabled,
portions (according to the 'tag') as well as the level, can be
Levels and tags are automatically inserted into the stream (for
post-filtering if desired).
We generally have different logs/streams for different types of
logging: errors, warnings, developer messages, determinism checks:
ERROR_LOG(...) << ...;
WARNING_LOG(...) << ...;
Which of course can be tied (at runtime) to the same stream or
There's always the push for "speed", so a compile-time disabling
(akin to NDEBUG for asserts) of certain streams is required.
Note: we're not using boost logging, just because we've already got
something that works.
