INHERITANCE

9        Log::Report::Util
10          is a Exporter

SYNOPSIS

13        my ($language, $territory, $charset, $modifier)
14           = parse_locale 'nl_BE.utf-8@home';
15
16        my @take = expand_reasons 'INFO-ERROR,PANIC';

DESCRIPTION

19       This module collects a few functions and definitions which are shared
20       between different components in the Log::Report infrastructure.  They
21       should not be needed for end-user applications, although this man-page
22       may contain some useful background information.

FUNCTIONS

25   Reasons
26       expand_reasons($reasons)
27           Returns a sub-set of all existing message reason labels, based on
28           the content $reasons string. The following rules apply:
29
30            REASONS     = BLOCK [ ',' BLOCKS ] | ARRAY-of-REASON
31            BLOCK       = '-' TO | FROM '-' TO | ONE | SOURCE
32            FROM,TO,ONE = 'TRACE' | 'ASSERT' | ,,, | 'PANIC'
33            SOURCE      = 'USER' | 'PROGRAM' | 'SYSTEM' | 'FATAL' | 'ALL' | 'NONE'
34
35           The SOURCE specification group all reasons which are usually
36           related to the problem: report about problems caused by the user,
37           reported by the program, or with system interaction.
38
39           example: of expended REASONS
40
41            WARNING-FAULT # == WARNING,MISTAKE,ERROR,FAULT
42            WARNING,INFO  # == WARNING,INFO
43            -INFO         # == TRACE-INFO
44            ALERT-        # == ALERT,FAILURE,PANIC
45            USER          # == MISTAKE,ERROR
46            ALL           # == TRACE-PANIC
47            FATAL         # == ERROR,FAULT,FAILURE,PANIC [1.07]
48            NONE          # ==
49
50       is_fatal($reason)
51           Returns true if the $reason is severe enough to cause an exception
52           (or program termination).
53
54       is_reason($name)
55           Returns true if the STRING is one of the predefined REASONS.
56
57       use_errno($reason)
58
59   Modes
60       Run-modes are explained in Log::Report::Dispatcher.
61
62       mode_accepts($mode)
63           Returns something acceptable by expand_reasons()
64
65       mode_number($name|$mode)
66           Returns the $mode as number.
67
68       must_show_location($mode, $reason)
69       must_show_stack($mode, $reason)
70
71   Other
72       escape_chars(STRING)
73           Replace all escape characters into their readable counterpart.  For
74           instance, a new-line is replaced by backslash-n.
75
76       parse_locale(STRING)
77           Decompose a locale string.
78
79           For simplicity of the caller's code, the capatization of the
80           returned fields is standardized to the preferred, although the
81           match is case- insensitive as required by the RFC. The territory in
82           returned in capitals (ISO3166), the language is lower-case
83           (ISO639), the script as upper-case first, the character-set as
84           lower-case, and the modifier and variant unchanged.
85
86           In LIST context, four elements are returned: language, territory,
87           character-set (codeset), and modifier.  Those four are important
88           for the usual unix translationg infrastructure.  Only the "country"
89           is obligatory, the others can be "undef".  It may also return "C"
90           and "POSIX".
91
92           In SCALAR context, a HASH is returned which can contain more
93           information: language, script, territory, variant, codeset, and
94           modifiers.  The variant (RFC3066 is probably never used)
95
96       pkg2domain( $package, [$domain, $filename, $line] )
97           With $domain, $filename and $line, this registers a location where
98           the textdomain is specified.  Each $package can only belong to one
99           $domain.
100
101           Without these parameters, the registered domain for the $package is
102           returned.
103
104       to_html($string)
105           [1.02] Escape HTML volatile characters.
106
107       unescape_chars(STRING)
108           Replace all backslash-something escapes by their escape character.
109           For instance, backslash-t is replaced by a tab character.
