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.
