Log::Report::Util - helpful routines to Log::Report
Log::Report::Util is a Exporter
This module collects a few functions and definitions which are shared between different components in the Log::Report infrastructure. They should not be needed for end-user applications, although this man-page may contain some useful background information.
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
Returns true if the $reason is severe enough to cause an exception (or program termination).
Returns true if the STRING is one of the predefined REASONS.
Run-modes are explained in Log::Report::Dispatcher.
Returns something acceptable by expand_reasons()
Returns the $mode as number.
Replace all escape characters into their readable counterpart. For instance, a new-line is replaced by backslash-n.
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
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)
With $domain, $filename and $line, this registers a location where the textdomain is specified. Each $package can only belong to one $domain.
Without these parameters, the registered domain for the $package is returned.
Replace all backslash-something escapes by their escape character. For instance, backslash-t is replaced by a tab character.
my ($language, $territory, $charset, $modifier) = parse_locale 'nl_BE.utf-8@home'; my @take = expand_reasons 'INFO-ERROR,PANIC';
