BASIC ====== * C++ logging library, depends on [`ccflag`](https://github.com/ccalvin/ccflag "C++ Command Line Flags Parser"). * Failure handler for windows, using [`StackWalker`](https://stackwalker.codeplex.com). * Failure handler for unix, idea is from [`DeathHandler`](https://github.com/vmarkovtsev/DeathHandler). API ====== ```cpp // @argv0 argv[0] or any valid string for a file name. void init_cclog(const std::string& argv0); // write all buffered logs to destination and stop the logging thread. void StopLogging(); ``` USAGE ====== * Notes > `LOG` ==> log to file, bufferd > `ELOG` ==> log to stderr and file, buffered > `CHECK` ==> abort if check failed > `DLOG` and `DCHECK` ==> do nothing if `NDEBUG` is defined * Simple Example ```cpp LOG << "hello" << ' ' << "world"; LOG_IF(1 + 1 == 2) << "1 + 1 = 2"; ELOG << L"hello again"; CHECK_EQ(1, 2) << "1 != 2"; ``` TEST ====== * Build ==> cd test && ./build.sh * Normal Test ```cpp vin@envy:~/cc/cclog/test$ ./exe 0419 16:43:16 8964 test.cc:59] hello world 0419 16:43:16 8964 test.cc:62] hello again vin@envy:~/cc/cclog/test$ cat exe.log 0419 16:43:16 8964 test.cc:50] b: true 0419 16:43:16 8964 test.cc:51] c: x 0419 16:43:16 8964 test.cc:52] i: -32 0419 16:43:16 8964 test.cc:53] d: 3.14159 0419 16:43:16 8964 test.cc:54] &c: 0x7fff28502ac8 0419 16:43:16 8964 test.cc:55] &i: 0x7fff28502acc 0419 16:43:16 8964 test.cc:56] b is true 0419 16:43:16 8964 test.cc:59] hello world 0419 16:43:16 8964 test.cc:62] hello again ``` * Exception Handler (-f=segv, chk or fpe) ```cpp vin@envy:~/cc/cclog/test$ ./exe -f=segv vin@envy:~/cc/cclog/test$ cat exe.log 0419 23:36:26 2997 test.cc:50] b: true 0419 23:36:26 2997 test.cc:51] c: x 0419 23:36:26 2997 test.cc:52] i: -32 0419 23:36:26 2997 test.cc:53] d: 3.14159 0419 23:36:26 2997 test.cc:54] &c: 0x7fff926903a8 0419 23:36:26 2997 test.cc:55] &i: 0x7fff926903ac 0419 23:36:26 2997 test.cc:56] b is true 0419 23:36:26 2997 test.cc:59] hello world 0419 23:36:26 2997 test.cc:62] hello again <segmentation fault> #0 0x4044F8 in xx::A::fa(int) at /home/vin/cc/cclog/test/test.cc:14 #1 0x404526 in xx::B::fb(int) at /home/vin/cc/cclog/test/test.cc:23 #2 0x404548 in xx::C::fc(int) at /home/vin/cc/cclog/test/test.cc:30 #3 0x40456A in xx::D::fd(int) at /home/vin/cc/cclog/test/test.cc:37 #4 0x404019 in main at /home/vin/cc/cclog/test/test.cc:67 #5 0x21EC5 in __libc_start_main at /build/buildd/eglibc-2.19/csu/libc-start.c:321 #6 0x403B6F in _start at /home/vin/cc/cclog/test/exe ``` * Flags for cclog ```cpp --alsolog2stderr: log to stderr and file type: bool default: false from: ../src/cclog.cc --log2stderr: log to stderr only type: bool default: false from: ../src/cclog.cc --log_dir: log dir type: string default: "" from: ../src/cclog.cc --max_log_file_size: max log file size, default: 128M type: int64 default: 128 << 20 from: ../src/cclog.cc ```
