* Very fast (see [benchmarks](#benchmarks) below).
|
||||
* Headers only, just copy and use. Or use as a compiled library.
|
||||
* Feature rich formatting, using the excellent [fmt](https://github.com/fmtlib/fmt) library.
|
||||
* [Backtrace](#backtrace-support) support - store debugging messages in a ring buffer for later inspection.
|
||||
* Fast asynchronous mode (optional)
|
||||
* [Custom](https://github.com/gabime/spdlog/wiki/3.-Custom-formatting) formatting.
|
||||
* Multi/Single threaded loggers.

#### Cloning loggers
|

#### Backtrace support
|
||||
```c++
|
||||
// clone a logger and give it new name.
|
||||
// Useful for creating subsystem loggers from some "root" logger
|
||||
void clone_example()
|
||||
// Loggers can store in a ring buffer all messages (including debug/trace) for later inspection.
|
||||
// When needed, call dump_backtrace() to see what happened:
|
||||
spdlog::enable_backtrace(32); // create ring buffer with capacity of 32 messages
|
||||
for(int i = 0; i < 100; i++)
|
||||
{
|
||||
auto network_logger = spdlog::get("root")->clone("network");
|
||||
network_logger->info("Logging network stuff..");
|
||||
spdlog::debug("Backtrace message {}", i); // not logged yet..
|
||||
}
|
||||
// e.g. if some error happened:
|
||||
spdlog::dump_backtrace(); // log them now!
