Question 1

How to set up g3log with CMake in a C++ project?

Accepted Answer

Refer to the building.md documentation for configuration steps; it involves adding the source files to your CMakeLists.txt and linking the library, with no external dependencies for the core logger.

Question 2

G3log vs spdlog: which is better for performance?

Accepted Answer

G3log emphasizes crash safety and stable worst-case latency with asynchronous logging, while spdlog offers header-only convenience and potentially lower overhead in some scenarios; choose based on priority for reliability vs. ease of use.

Question 3

Does g3log support log rotation out of the box?

Accepted Answer

No, log rotation requires integrating third-party sinks from the g3sinks repository, such as the log rotate sink, as the core library focuses on logging mechanics rather than file management.

Question 4

How to add custom logging levels in g3log?

Accepted Answer

Use the API.md guidelines to define or replace logging levels through configuration, allowing dynamic level adjustments if enabled, but this requires manual implementation for filtering.

Question 5

Is g3log thread-safe for multi-threaded applications?

Accepted Answer

Yes, its asynchronous design handles concurrent log calls safely by queuing them in a background thread, ensuring minimal contention and data integrity, as noted in the performance section.

Question 6

Can g3log log to multiple files or sinks simultaneously?

Accepted Answer

Yes, you can add multiple sinks via the LogWorker, such as default file logger and custom sinks, enabling parallel logging to different outputs, though setup requires explicit configuration per sink.
