Per log level formatting about spdlog HOT 5 CLOSED

For now, the only documentation on custom formatters is the Wiki (the Wiki can be edited by anyone).

If the Wiki documentation lacks information, you are left to figure out how to create a custom formatter from an existing formatter implementation.
See: https://github.com/gabime/spdlog/blob/v1.12.0/include/spdlog/pattern_formatter-inl.h

Thank you for the reply.
Changing color is not enough for what I want to achieve.

Basically I want the following pattern if the level is below or equal to INFO (the color is only used for the level text):

But for other, more critical levels I want:

Thus it makes two distinct patterns, with a list of applicable levels for each one.

The color range format flag (start: %^, end %$) can be used to adjust the color range of the message, but the ability to set it per log level is not supported.

You may want to consider the custom formatter.

Yep I know how to create the pattern. My point was about how to affect pattern to level.
Any doc please about 'custom formatter' I don't manage to find it.
Thanks
