// pEpLog
|
|
// ======
|
|
// a "to be kept ultra small and simple" logging unit.
|
|
// featuring:
|
|
// * pEpLog macro that will be eliminated in release-builds (-DNDEBUG=1)
|
|
// * thread safe (no interleave when logging from diff threads)
|
|
// * OS dependent backend switches:
|
|
// * android: __android_log_print
|
|
// * all other OS: cout
|
|
// * runtime enabled/disabled switch (global)
|
|
//
|
|
// You might want more and more features, but the feature-policy is very restrictive, and there is a
|
|
// primary design goal to keep it simple, maintainable and portable.
|
|
//
|
|
// How to use:
|
|
// include <pEpLog.hh>
|
|
// use the macro pEpLog(msg) to do logging
|
|
// use NDEBUG=1 to turn logging on/off at compile-time
|
|
// use set_enabled(bool) to turn logging on/off at runtime
|
|
// use set_enabled_<backend>(bool) to turn logging on/off per backend
|
