The C option defaults to false. Exported by default, or using the C<:STD> tag. =head2 debug("message string" [,VERBOSE]) Records a debug message on the stack, and prints it to C (or actually C<$DEBUG_FH>, see the C section below), if the C option is true. The C option defaults to false. Exported by default, or using the C<:STD> tag. =head2 error("error string" [,VERBOSE]) Records an error on the stack, and prints it to C (or actually C<$ERROR_FH>, see the C sections below), if the C option is true. The C options defaults to true. Exported by default, or using the C<:STD> tag. =cut { package Log::Message::Handlers; sub msg { my $self = shift; my $verbose = shift || 0; ### so you don't want us to print the msg? ### return if defined $verbose && $verbose == 0; my $old_fh = select $Log::Message::Simple::MSG_FH; print '['. $self->tag ().

Exported by using the C<:CARP> tag. =head1 CLASS METHODS =head2 Log::Message::Simple->stack() Retrieves all the items on the stack. Since C is implemented using C, consult its manpage for the function C to see what is returned and how to use the items. =head2 Log::Message::Simple->stack_as_string([TRACE]) Returns the whole stack as a printable string. If the C option is true all items are returned with C output, rather than just the message. C defaults to false. =head2 Log::Message::Simple->flush() Removes all the items from the stack and returns them. Since C is implemented using C, consult its manpage for the function C to see what is returned and how to use the items. =cut BEGIN { use Exporter; use Params::Check qw[ check ]; use vars qw[ @EXPORT @EXPORT_OK %EXPORT_TAGS @ISA ];; @ISA = 'Exporter'; @EXPORT = qw[error msg debug]; @EXPORT_OK = qw[carp cluck croak confess]; %EXPORT_TAGS = ( STD => \@EXPORT, CARP => \@EXPORT_OK, ALL => [ @EXPORT, @EXPORT_OK ], ); my $log = new Log::Message; for my $func ( @EXPORT, @EXPORT_OK ) { no strict 'refs'; ### up the carplevel for the carp emulation ### functions *$func = sub { local $Carp::CarpLevel += 2 if grep { $_ eq $func } @EXPORT_OK;
