Possibility to delete Backtrace Start and Backtrace End

[markusmu0]

Hi,
is there a possibility to delete Backtrace Start and End message?

If not: Is there another possibility to buffer/store some debug messages and only dump them, when a condition is true?

Use ringbuffer_sink instead.

I Don't think that this is a duplicate:
I am searching for a possibility

1. to dump the output on a condition and not only if the buffer is full
2. to throw away the logs if the condition is false
3. to have a complete logger with multiple sinks with this behavior

Everything of this can be done with backtrace so the only problem is the start and end message

If compatibility is not broken, please submit PR.

PR was rejected by gabime. Thus, the problem still exists. Is there another solution for this?

spdlog does not provide.

Both backtracer and ringbuffer_sink use spdlog::details::circular_q, so create a custom sink that buffers messages using spdlog::details::circular_q.

spdlog/include/spdlog/details/backtracer.h

Line 22 in 326f887

circular_q<log_msg_buffer> messages_;

spdlog/include/spdlog/sinks/ringbuffer_sink.h

Line 66 in 326f887

details::circular_q<details::log_msg_buffer> q_;
