NAME

Log::ger::Level::FromEnv - Set default log level from some environment variables

VERSION

version 0.005

SYNOPSIS

 use Log::ger;
 use Log::ger::Level::FromEnv;

 log_warn "blah ...";

DESCRIPTION

This module sets $Log::ger::Current_Level based on hints from several environment variables: LOG_LEVEL (for example, if set to warn or warning will set the log level to warning (30)), TRACE (if true, will set log level to trace (60)), DEBUG (if true, will set log level to debug (50)), VERBOSE (if true, will set log level to info (40)), QUIET (if true, will set log level to error (20)).

This is convenient for CLI programs or one-liners.

SEE ALSO

Log::ger::App also observes the same set of environment variables.

Log::ger::Screen uses us.
