NAME
Log::Message::Simple − Simplified interface to Log::Message
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"
