/home/runner/work/EICrecon/EICrecon/src/extensions/spdlog/SpdlogMixin.h

Initializes logger through current LogService

Parameters

app	- JApplication pointer, as obtained from GetApplication()
param_prefix	- name of both logger and user parameter
default_level	- optional - default log level, overrides default logging level : trace, debug, info, warn, err, critical, off

Remarks

: Each logger is cloned from spdlog::default_logger(). This allows to set the default level and output formatting on a global system level. But sometimes it is useful to provide default log level independently on what is set by the system. Again we are about DEFAULT value if no user flag is provided

InitLogger(GetApplication(), "BTRK:TrackerHits") // Default log level is set the same as in system InitLogger(GetApplication(), "BTRK:TrackerHits", "info") // By default log level is info

will create "BTRK:TrackerHits" logger and check -PBTRK:TrackerHits:LogLevel user parameter
