NAME

       Log::Report::Util - helpful routines to Log::Report

INHERITANCE

	Log::Report::Util
	  is a Exporter

DESCRIPTION

       This module collects a few functions and definitions which are shared between different components in the Log::Report infrastructure.

FUNCTIONS

       escape_chars(STRING)
	   Replace all escape characters into their readable counterpart.  For instance, a new-line is replaced by backslash-n.

       expand_reasons(REASONS)
	   Returns a sub-set of all existing message reason labels, based on the content REASONS string. The following rules apply:
	    REASONS = BLOCK [ ',' BLOCKS]
	    BLOCK   = '-' TO | FROM '-' TO | ONE | SOURCE
	    FROM,TO,ONE = 'TRACE' | 'ASSERT' | ,,, | 'PANIC'
	    SOURCE  = 'USER' | 'PROGRAM' | 'SYSTEM' | 'ALL'

	   The SOURCE specification group all reasons which are usually related to the problem: report about problems caused by the user, reported
	   by the program, or with system interaction.

	   example: of expended REASONS

	    WARNING-FAULT # == WARNING,MISTAKE,ERROR,FAULT
	    -INFO	  # == TRACE-INFO
	    ALERT-	  # == ALERT,FAILURE,PANIC
	    USER	  # == MISTAKE,ERROR
	    ALL 	  # == TRACE-PANIC

       parse_locale(STRING)
	   Decompose a locale string.

	   For simplicity of the caller's code, the capatization of the returned fields is standardized to the preferred, although the match is
	   case- insensitive as required by the RFC. The territory in returned in capitals (ISO3166), the language is lower-case (ISO639), the
	   script as upper-case first, the character-set as lower-case, and the modifier and variant unchanged.

	   In LIST context, four elements are returned: language, territory, character-set (codeset), and modifier.  Those four are important for
	   the usual unix translationg infrastructure.	Only the "country" is obligatory, the others can be "undef".  It may also return "C" and
	   "POSIX".

	   In SCALAR context, a HASH is returned which can contain more information: language, script, territory, variant, codeset, and modifiers.
	   The variant (RFC3066 is probably never used)

       unescape_chars(STRING)
	   Replace all backslash-something escapes by their escape character.  For instance, backslash-t is replaced by a tab character.

SYNOPSYS

	my ($language, $territory, $charset, $modifier)
	   = parse_locale 'nl_BE.utf-8@home';

	my @take = expand_reasons 'INFO-ERROR,PANIC';

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');
