| 132 | .TH I18N::LangTags::Detect 3 "2001-09-21" "perl v5.8.8" "Perl Programmers Reference Guide" | |
| 133 | .SH "NAME" | |
| 134 | I18N::LangTags::Detect \- detect the user's language preferences | |
| 135 | .SH "SYNOPSIS" | |
| 136 | .IX Header "SYNOPSIS" | |
| 137 | .Vb 2 | |
| 138 | \& use I18N::LangTags::Detect; | |
| 139 | \& my @user_wants = I18N::LangTags::Detect::detect(); | |
| 140 | .Ve | |
| 141 | .SH "DESCRIPTION" | |
| 142 | .IX Header "DESCRIPTION" | |
| 143 | It is a common problem to want to detect what language(s) the user would | |
| 144 | prefer output in. | |
| 145 | .SH "FUNCTIONS" | |
| 146 | .IX Header "FUNCTIONS" | |
| 147 | This module defines one public function, | |
| 148 | \&\f(CW\*(C`I18N::LangTags::Detect::detect()\*(C'\fR. This function is not exported | |
| 149 | (nor is even exportable), and it takes no parameters. | |
| 150 | .PP | |
| 151 | In scalar context, the function returns the most preferred language | |
| 152 | tag (or undef if no preference was seen). | |
| 153 | .PP | |
| 154 | In list context (which is usually what you want), | |
| 155 | the function returns a | |
| 156 | (possibly empty) list of language tags representing (best first) what | |
| 157 | languages the user apparently would accept output in. You will | |
| 158 | probably want to pass the output of this through | |
| 159 | \&\f(CW\*(C`I18N::LangTags::implicate_supers_tightly(...)\*(C'\fR | |
| 160 | or | |
| 161 | \&\f(CW\*(C`I18N::LangTags::implicate_supers(...)\*(C'\fR, like so: | |
| 162 | .PP | |
| 163 | .Vb 4 | |
| 164 | \& my @languages = | |
| 165 | \& I18N::LangTags::implicate_supers_tightly( | |
| 166 | \& I18N::LangTags::Detect::detect() | |
| 167 | \& ); | |
| 168 | .Ve | |
| 169 | .SH "ENVIRONMENT" | |
| 170 | .IX Header "ENVIRONMENT" | |
| 171 | This module looks for several environment variables, including | |
| 172 | \&\s-1REQUEST_METHOD\s0, \s-1HTTP_ACCEPT_LANGUAGE\s0, | |
| 173 | \&\s-1LANGUAGE\s0, \s-1LC_ALL\s0, \s-1LC_MESSAGES\s0, and \s-1LANG\s0. | |
| 174 | .PP | |
| 175 | It will also use the Win32::Locale module, if it's installed. | |
| 176 | .SH "SEE ALSO" | |
| 177 | .IX Header "SEE ALSO" | |
| 178 | I18N::LangTags, Win32::Locale, Locale::Maketext. | |
| 179 | .PP | |
| 180 | (This module's core code started out as a routine in Locale::Maketext; | |
| 181 | but I moved it here once I realized it was more generally useful.) | |
