The C option defaults to false. =head2 msg() An alias for C. =head2 cp_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. =head2 error() An alias for C. =head1 CLASS METHODS =head2 CPANPLUS::Error->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 CPANPLUS::Error->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 CPANPLUS::Error->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 @ISA $ERROR_FH $MSG_FH]; @ISA = 'Exporter'; @EXPORT = qw[cp_error cp_msg error msg]; my $log = new Log::Message; for my $func ( @EXPORT ) { no strict 'refs'; my $prefix = 'cp_'; my $name = $func; $name =~ s/^$prefix//g; *$func = sub { my $msg = shift; ### no point storing non-messages return unless defined $msg; $log->store( message => $msg, tag => uc $name, level => $prefix . $name, extra => [@_] ); }; } sub flush { my @foo = $log->flush; return unless @foo; return reverse @foo; } sub stack { return $log->retrieve( chrono => 1 ); } sub stack_as_string { my $class = shift; my $trace = shift() ? 1 : 0; return join $/, map { '[' . $_->tag .
