CPANPLUS::Error(3pm)                  Perl Programmers Reference Guide                  CPANPLUS::Error(3pm)



NAME
       CPANPLUS::Error - error handling for CPANPLUS

SYNOPSIS
           use CPANPLUS::Error qw[cp_msg cp_error];

DESCRIPTION
       This module provides the error handling code for the CPANPLUS libraries, and is mainly intended for
       internal use.

FUNCTIONS
   cp_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.

   msg()
       An alias for "cp_msg".

   cp_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.

   error()
       An alias for "cp_error".

CLASS METHODS
   CPANPLUS::Error->stack()
       Retrieves all the items on the stack. Since "CPANPLUS::Error" is implemented using "Log::Message",
       consult its manpage for the function "retrieve" to see what is returned and how to use the items.

   CPANPLUS::Error->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.

   CPANPLUS::Error->flush()
       Removes all the items from the stack and returns them. Since "CPANPLUS::Error" 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.
