SYNOPSIS

use Log::Message::Simple qw[msg error debug
carp croak cluck confess];
use Log::Message::Simple qw[:STD :CARP];
### standard reporting functionality
msg( "Connecting to database", $verbose );
error( "Database connection failed: $@", $verbose );
debug( "Connection arguments were: $args", $debug );
### standard carp functionality
carp( "Wrong arguments passed: @_" );
croak( "Fatal: wrong arguments passed: @_" );
cluck( "Wrong arguments passed -- including stacktrace: @_" );
confess("Fatal: wrong arguments passed -- including stacktrace: @_" );
### retrieve individual message
my @stack = Log::Message::Simple->stack;
my @stack = Log::Message::Simple->flush;
### retrieve the entire stack in printable form
my $msgs = Log::Message::Simple->stack_as_string;
my $trace = Log::Message::Simple->stack_as_string(1);
### redirect output
local $Log::Message::Simple::MSG_FH = \*STDERR;
local $Log::Message::Simple::ERROR_FH = \*STDERR;
local $Log::Message::Simple::DEBUG_FH = \*STDERR;

### force a stacktrace on error
local $Log::Message::Simple::STACKTRACE_ON_ERROR = 1

DESCRIPTION

This module provides standardized logging facilities using the "Log::Message" module.

FUNCTIONS

msg(message string [,VERBOSE])

Records a message on the stack, and prints it to "STDOUT" (or actually $MSG_FH, see the "GLOBAL VARIABLES" section below), if the "VERBOSE" option is true. The "VERBOSE" option defaults to false.

Exported by default, or using the ":STD" tag.

debug(message string [,VERBOSE])

Records a debug message on the stack, and prints it to "STDOUT" (or actually $DEBUG_FH, see the "GLOBAL VARIABLES" section below), if the "VERBOSE" option is true. The "VERBOSE" option defaults to false.

Exported by default, or using the ":STD" tag.

error(error string [,VERBOSE])

Records an error on the stack, and prints it to "STDERR" (or actually $ERROR_FH, see the "GLOBAL VARIABLES" sections below), if the "VERBOSE" option is true. The "VERBOSE" options defaults to true.

Exported by default, or using the ":STD" tag.

carp();

Provides functionality equal to "Carp::carp()" while still logging to the stack.

Exported by using the ":CARP" tag.

croak();

Provides functionality equal to "Carp::croak()" while still logging to the stack.

Exported by using the ":CARP" tag.

confess();

Provides functionality equal to "Carp::confess()" while still logging to the stack.

Exported by using the ":CARP" tag.

cluck();

Provides functionality equal to "Carp::cluck()" while still logging to the stack.

Exported by using the ":CARP" tag.

CLASS METHODS

Log::Message::Simple->stack()

Retrieves all the items on the stack. Since "Log::Message::Simple" is implemented using "Log::Message", consult its manpage for the function "retrieve" to see what is returned and how to use the items.

Log::Message::Simple->stack_as_string([TRACE])

Returns the whole stack as a printable string. If the "TRACE" option is true all items are returned with "Carp::longmess" output, rather than just the message. "TRACE" defaults to false.

Log::Message::Simple->flush()

Removes all the items from the stack and returns them. Since "Log::Message::Simple" is implemented using "Log::Message", consult its manpage for the function "retrieve" to see what is returned and how to use the items.

GLOBAL VARIABLES

$ERROR_FH

This is the filehandle all the messages sent to "error()" are being printed. This defaults to *STDERR.

$MSG_FH

This is the filehandle all the messages sent to "msg()" are being printed. This default to *STDOUT.

$DEBUG_FH

This is the filehandle all the messages sent to "debug()" are being printed. This default to *STDOUT.

$STACKTRACE_ON_ERROR

If this option is set to "true", every call to "error()" will generate a stacktrace using "Carp::shortmess()". Defaults to "false"
