cfLog

A tiny, flexible, portable and thread-safe C++ logger for developers

Compile

You can compile the cfLog as a static link library or a dynamic link library, based on your preferences. The CMake tool is required to build the libraries using our CMakeLists.txt. The procedure is quit simple on Linux & Mac system (also easy with CMake-GUI on Windows system):

• mkdir build
• cd build
• cmake -DCMAKE_BUILD_TYPE=Debug ..
• make
• sudo make install

That's all, and you can find the samples in 'build/bin' directory, and the libraries are in 'build/lib' directory.

Usage

cfLog is easy to use. Basically, it could be used in two styles:

• cf::utils::LOG*() Singleto macro mode (单实例宏模式)
• C++ object cf::utils::Log Multi-instances class-object mode(多实例类对象模式)

Samples

using namespace cf::utils;
...

int a=123;
char ch='a';
float f=1.234;
const char *str="世界你好！";
   
setLogLevel(LogLevel::INFO);
enableLogPosition(true, true);
setLogFile("test.txt", true);

LOGI("A")<<a<<":Hello!!!";
setLogFile("log.txt", true);
TRACEI("world!");
LOGE("")<<"error!";
setLogFile();
LOGW("warn...");
TRACEE("debug error");

LOGI("hello int:%d, char:%c, float:%f, string:%s", a, ch, f, str);
TRACEFF("hello int:%d, char:%c, float:%f, string:%s", a, ch, f, str);

Log log;
log()<<"kaka";
log(LogLevel::INFO, "warningTag")<<"This is a warn";

TRACEF("dummy format string");
std::string str2="string test";
TRACEF("where is the string:%s", str2.c_str());

Documents

cfLog uses doxygen to generate the source document. It is easy with doxygen: doxygen Doxyfile
