58 Every string that should be translated must be recognized by our
59 translation helper script C<script/locales.pl> somehow. It recognizes
60 certain function calls as translation instructions and extracts its
61 arguments for translation by developers/translators.
63 This works well for calls that occur during execution time: C<<
64 $::locale->text("Untranslated") >>. However, for untranslated strings
65 that need to be used at compile time this fails in subtle and not so
66 subtle ways. If it happens in a module that is C<use>d directly from
67 the dispatcher then C<$::locale> is not defined and such a call would
68 end in an error. For modules like controllers that are C<require>d
69 during execution time it seems to work, but in FastCGI situations this
70 means that the first call determines the language and all subsequent
71 calls end up using the same language no matter which language the user
74 This class solves the issue by providing a small function called L<t8>
75 which can be used instead of C<< $::locale->text() >>. It is
76 recognized by C<script/locales.pl>. The untranslated string given to
77 L<t8> is stored in an instance of C<SL::Locale::String> and translated
78 only when requested either by calling L<translated> or by
81 Instances of this class can safely be handed over to C<<
82 $::locale->text() >> which knows how to handle them (and not to
85 The function L<t8> is exported by default.
89 =head2 EXPORTED FUNCTIONS
93 =item C<t8 $untranslated_string>
95 Returns a new instance of C<SL::Locale::String> and sets its
96 L<untranslated> member to C<$untranslated_string>. This function is
97 exported and cannot be called as a class or instance method.
101 =head2 INSTANCE FUNCTIONS
105 =item C<untranslated [$new_untranslated]>
107 Gets or sets the untranslated string.
111 Returns the translated version of the untranslated string. Translation
112 occurs when this function is called and not when the object instance
115 This function is also called during stringification.
