NAME

       HTML::FormHandler::TraitFor::I18N - localization

VERSION

       version 0.40013

       language_handle, _build_language_handle

       Holds a Locale::Maketext (or other duck_type class with a 'maketext' method) language handle. The language handle is used to localize the
       error messages in the field's 'add_error' method. It's also used in various places in rendering to localize labels and button values, etc.

       The builder for this attribute gets the Locale::Maketext language handle from the environment variable $ENV{LANGUAGE_HANDLE}:

	   $ENV{LANGUAGE_HANDLE} = HTML::FormHandler::I18N->get_handle('en_en');

       ...or creates a default language handler using HTML::FormHandler::I18N.	You can pass in an existing Locale::MakeText subclass instance or
       create one in a builder.

       In a form class:

	   sub _build_language_handle { MyApp::I18N::abc_de->new }

       Passed into new or process:

	   my $lh = MyApp::I18N::abc_de->new;
	   my $form = MyApp::Form->new( language_handle => $lh );

       If you do not set the language_handle, then Locale::Maketext and/or I18N::LangTags may guess, with unexpected results.

       You can use non-Locale::Maketext language handles, such as Data::Localize.  There's an example of building a Data::Localize language handle
       in t/xt/locale_data_localize.t in the distribution.

       If you don't want a particular error message to go through localization, you can use 'push_errors' and 'push_form_errors' instead of
       'add_error' and 'add_form_errors'.

       Example of getting the language handle from the Catalyst context (where the Catalyst context is passed in with 'ctx'):

	   has '+language_handle' => ( builder => 'get_language_handle_from_ctx' );
	   sub get_language_handle_from_ctx {
	       my $self = shift;
	       return MyApp::I18N->get_handle(
		   @{ $self->ctx->languages } );
	   }

NAME

       I18N::LangTags::Detect - detect the user's language preferences

SYNOPSIS

	 use I18N::LangTags::Detect;
	 my @user_wants = I18N::LangTags::Detect::detect();

DESCRIPTION

       It is a common problem to want to detect what language(s) the user would prefer output in.

FUNCTIONS

       This module defines one public function, "I18N::LangTags::Detect::detect()".  This function is not exported (nor is even exportable), and
       it takes no parameters.

       In scalar context, the function returns the most preferred language tag (or undef if no preference was seen).

       In list context (which is usually what you want), the function returns a (possibly empty) list of language tags representing (best first)
       what languages the user apparently would accept output in.  You will probably want to pass the output of this through
       "I18N::LangTags::implicate_supers_tightly(...)"	or "I18N::LangTags::implicate_supers(...)", like so:

	 my @languages =
	   I18N::LangTags::implicate_supers_tightly(
	     I18N::LangTags::Detect::detect()
	   );

ENVIRONMENT

       This module looks for several environment variables, including REQUEST_METHOD, HTTP_ACCEPT_LANGUAGE, LANGUAGE, LC_ALL, LC_MESSAGES, and
       LANG.

       It will also use the Win32::Locale module, if it's installed.

SEE ALSO

       I18N::LangTags, Win32::Locale, Locale::Maketext.

       (This module's core code started out as a routine in Locale::Maketext; but I moved it here once I realized it was more generally useful.)
