Log::Report::Die(3pm)					User Contributed Perl Documentation				     Log::Report::Die(3pm)

NAME
Log::Report::Die - compatibility routines with Perl's die/croak/confess INHERITANCE
Log::Report::Die is a Exporter Functions die_decode(STRING) The STRING is the content of $@ after an eval() caught a die(). croak(), or confess(). This routine tries to convert this into parameters for Log::Report::report(). This is done in a very smart way, even trying to find the stringifications of $!. Return are four elements: the error string which is used to trigger a "Log::Report" compatible "die()", and the options, reason, and text message. The options is a HASH which, amongst other things, may contain a stack trace and location. Translated components will have exception classes "perl", and "die" or "confess". On the moment, the "croak" cannot be distiguished from the "confess" (when used in package main) or "die" (otherwise). The returned reason depends on whether the translation of the current $! is found in the STRING, and the presence of a stack trace. The following table is used: errstr stack => reason no no ERROR (die) application internal problem yes no FAULT (die) external problem, think open() no yes PANIC (confess) implementation error yes yes ALERT (confess) external problem, caught = @{$opt{stack}} ? ($opt{errno} ? 'ALERT' : 'PANIC') : ($opt{errno} ? 'FAULT' : 'ERROR'); SEE ALSO
