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 ] | ARRAY-of-REASON
BLOCK = '-' TO | FROM '-' TO | ONE | SOURCE
FROM,TO,ONE = 'TRACE' | 'ASSERT' | ,,, | 'PANIC'
SOURCE = 'USER' | 'PROGRAM' | 'SYSTEM' | 'FATAL' | 'ALL' | 'NONE'
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
WARNING,INFO # == WARNING,INFO
-INFO # == TRACE-INFO
ALERT- # == ALERT,FAILURE,PANIC
USER # == MISTAKE,ERROR
ALL # == TRACE-PANIC
FATAL # == ERROR,FAULT,FAILURE,PANIC [1.07]
NONE # ==
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 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)
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.
[1.02] Escape HTML volatile characters.
Replace all backslash-something escapes by their escape character. For instance, backslash-t is replaced by a tab character.
