I think QLog from QTopia was very good.
You define your category in your project and QLog will define a static bool for
each category e.g.
# define QLOG_ENABLE(dbgcat) \
class dbgcat##_QLog : public QLogBase { \
public: \
static inline bool enabled() { return 1; }\
};
A log entry was done by:
# define qLog(dbgcat) if(!dbgcat##_QLog::enabled()); else
dbgcat##_QLog::log(#dbgcat)
Misspelling can't be happening because you will get an compiler error.
No string compare are necessary because it uses the static category bool.
I think this is bloody fast and using this idea + adding a config file to
enable or disable Categories will be a good log system or not?
