use App::CELL::Message; # server messages: pass message code only, message text # will be localized to the site default language, if # assertainable, or, failing that, in English my $message = App::CELL::Message->new( code => 'FOOBAR' ) # and then we pass $message as an argument to # App::CELL::Status->new # client messages: pass message code and session id, # message text will be localized according to the user's language # preference setting my $message = App::CELL::Message->new( code => 'BARBAZ', session => $s_obj ); $msg_to_display = $message->App::CELL::Message->text; # a message may call for one or more arguments.

EXPORTS AND PUBLIC METHODS
This module provides the following public functions and methods:
new- construct a
text- get text of an existing object
max_size- get maximum size of a given message code
A App::CELL::Message object is a reference to a hash containing some or all of the following keys (attributes):
code- message code (see below)
text- message text
language- message language (e.g., English)
max_size- maximum number of characters this message is guaranteed not to exceed (and will be truncated to fit into)
truncated- boolean value: text has been truncated or not
The information in the hash is sourced from two places: the
$mesg hashref in this module (see "CONSTANTS") and the SQL database. The former is reserved for "system critical" messages, while the latter contains messages that users will come into contact with on a daily basis. System messages are English-only; only user messages are localizable.
The minimal list of supported languages, specified by their respective language tags (currently 'en-US' only).
See the W3C's "Language tags in HTML and XML" white paper for a detailed explanation of language tags:
And see here for list of all language tags:
App::CELL::Message module stores messages in a package variable,
$mesg (which is a hashref).
FUNCTIONS AND METHODS
Load messages (keys and values) from the relevant configuration file(s). Be re-entrant.
Construct a message object. Takes a message code and, optionally, a reference to an array of arguments. Returns the object. See "SYNOPSIS".
Accessor method for the 'code' attribute.
Accessor method for the 'args' attribute.
Accessor method for the 'text' attribute. Returns content of 'text' attribute, or "<NO_TEXT>" if it can't find any content.
