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';
