I18N::LangTags::Detect(3pm) Perl Programmers Reference Guide
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 at several environment variables: REQUEST_METHOD,
HTTP_ACCEPT_LANGUAGE, LANGUAGE, LC_ALL, LC_MESSAGES, and LANG.
It will also use the Win32::Locale module, if it's installed and
IGNORE_WIN32_LOCALE is not set to a true value in the environment.
SEE ALSO
I18N::LangTags(3), Win32::Locale(3), Locale::Maketext(3).
(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.)
