man Lire::Logger (3): Lire's logging interface.

SYNOPSIS

Any program:

use Lire::Logger qw/ lr_info lr_debug lr_warn /;
lr_info( "doing stuff " );
lr_debug( "debugging information" );
lr_warn( "encountered unexpected value: ", $value );
open( CFGFILE, "my.conf" ) or lr_err( "open error: ", $! );

DESCRIPTION

This module contains functions that should be used by everything in the Lire framework which should need logging.

All logging functions take any number of parameters that will be joined together to form the message (like print(), die(), warn() and friends).

lr_emerg()

This logs a message at the "emerg" level and aborts your program. This probably shouldn't be used.

lr_crit()

This logs a message at the "crit" level and aborts your program. This should only be used when something is really broken in the Lire program or the environment. It is used a few places in Lire when assertion that should really never fail (like a DLF file with the wrong number of fields).

lr_err()

This logs a message at the "err" level and usually aborts your program. (It is the equivalent of a die().) The program won't abort if it's used in an eval block. Uses this for error condition.

lr_warn()

This logs a message at the "warning" level. Perl's builtin warn is mapped to this function. Use this for non-fatal errors.

lr_notice()

This logs a message at the "notice" level. This should be used for significant informational messages that the user should see. (By default, the user will only see messages at level "notice" or higher.)

lr_info()

This logs a message at the "info" level. Use this for general informational messages.

lr_debug()

This logs a message at the "debug" level. Use this for debugging messages.
