NAME

OpenInteract2::I18N::Initializer - Read in localization messages and generate maketext classes

SYNOPSIS

my $init = OpenInteract2::I18N::Initializer->new;
$init->add_message_files( @some_message_files );
my $gen_classes = $init->run;
print "I generated the following classes: ", join( @{ $gen_classes } ), "\n";

DESCRIPTION

This class is generally only used by the OI2 startup procedure, which scans all packages for message files and adds them to this initializer, then runs it. The purpose of this class is to generate subclasses for use with Locale::Maketext. Those classes are fairly simple and generally only contain a package variable %Lexicon which L::M uses to work its magic.

CLASS METHODS

new()

Return a new object. Any parameters are ignored.

OBJECT METHODS

add_message_files( @fully_qualified_files )

Adds all files in @fully_qualified_files to its internal list of files to process. It does not process these files until run().

locate_global_message_files()

Finds all message files (that is, files ending in '.msg') in the global message directory as reported by the OpenInteract2::Context and adds them to the initializer. Normally only called by OpenInteract2::Setup.

Returns: arrayref of fully-qualified files added

run()

Reads messages from all files added via add_message_files() and generates language-specific subclasses for all messages found. (Once the subclasses are created the system does not know from where the messages come since all messages are flattened into a per-language data structure.) So the following:

file: msg-en.msg
keys:
  foo.title
  foo.intro
  foo.label.main

file: other_msg-en.msg
keys:
  baz.title
  baz.intro
  baz.conclusion

file: another_msg-en.msg
  bar.title
  bar.intro
  bar.error.notfound

would be flattened into:

lang: en
  foo.title
  foo.intro
  foo.label.main
  baz.title
  baz.intro
  baz.conclusion
  bar.title
  bar.intro
  bar.error.notfound

The method throws an exception on any of the following conditions:

  • Cannot open or read from one of the message files.

  • Cannot discern a language from the given filename. The language must be the last distinct set of characters before the file extension. The following are ok:

    myapp-en.msg
    myotherapp-en-MX.dat
    messages_en-HK.msg

    The following are not:

    english-messages.msg
    messages-en-part2.msg
    messagesen.msg
  • Cannot process the template used to generate the class.

  • Cannot evaluate the generated class.

Note that a duplicate key (that is, a key defined in multiple message files) will not generate an exception. Instead it will generate a logging message with an 'error' level.

See more about the format used for the message files in OpenInteract2::Manual::I18N.

Returns: arrayref of the names of the classes generated.
