the log file. Either useful data is buried (cannot be extracted) or inconsistently represented.
Some examples of representation;
After completion there were 3 leftovers and ... After completion there were <3> leftovers and ... After completion there were <3!unsigned int> leftovers and ... After completion there were <3!unsigned int/matching_profile> leftovers and
The last representation : what does "/matching_profile" mean? Based on what you've just printed above, how would you see the 3 value above? Like this: unsigned int leftovers_count; If so, the first 3 representations would be rather easy to implement.
...
You might argue that your library does not prevent such output. Which would
Indeed so ;)
be true. What I am suggesting is that a Boost logging library should provide explicit solutions to such issues. With such formalizations in place a much
Actually, I would expect a Boost Format library to handle those issues.
more ambitious viewer can be developed, giving a richer user experience than notepad or nano. Analysis can be more accurate, reliable and ambitious.
I'm all for that. However, I'd rather have a layer on top of Boost Logging, or completely separated, to handle your specific case, than to force the users onto the above scenario.
b) A customer requires a low-cost, low-tech, highly robust audit trail of all activity on their system. It is decided to log all events into text files. Each event involves a time, a unique identifier and a list of zero or more runtime values (i.e. parameters).
About "event involving a time, unique id, list of ..." - could we be talking about tags? I believe those should actually be what you want: http://torjo.com/log2/doc/html/namespaceboost_1_1logging_1_1tag.html
If I could write something like; #include <boost/logging.hpp>
void test_mul_levels_one_logger() { L_ << "hello world";}
I see you've posted a different email regarding to this - I'll answer that in a different email. Best, John -- http://John.Torjo.com -- C++ expert http://blog.torjo.com ... call me only if you want things done right
