- # MODULE DESCRIPTION: Message translation framework
- #
- # This module provides functions for translating messages in the user's
- # native language. Translations are stored in
- # <a href="http://www.gnu.org/software/gettext/">GNU gettext</a> translation
- # files (*.mo).
- #
- # <b>Notes:</b>
- # `l
- # - Translation files MUST be encoded in UTF-8 (without BOM).
- # - We use short locale names, as defined by http://www.loc.gov/standards/iso639-2/englangn.html
- # `l`

- # Ensures: Translation::T() and Translation::TF() will be usable.
- # Returns: Whether initialization succeeded. It is not fatal if
- # initialization failed: this module will automatically
- # fallback to using the original (English) strings.

- # Initialize the default translation object. Translation::T() and
- # Translation::TF() will only be usable after calling this function once.

- #
- # This function is meant for plugin developers, who have their translation files
- # stored in a different folder than OpenKore's. If you want to translate strings
- # in OpenKore, then you should use Translation::T() instead.

- # Example:
- # my $t = new Translation;

- # Translate $message.
- #
- # This symbol is automatically exported.
- #
- # See also: $translation->translate() and Translation::TF()
- #

- # use Translation;

- # String Translation::TF(String format, ...)
- # Requires: Translation::initDefault() must have been called once; $format must be encoded in UTF-8.
- # Ensures: the return value is encoded in UTF-8.
- #
- # Translate $format, and perform sprintf() formatting using the specified parameters.
- # This function is just a convenient way to write:<br>
- # <code>sprintf(T($format), ...);</code>
- #
- # This symbol is automatically exported.
- #
- # Example:
- # print(TF("Go to %s for more information", $url));
- sub TF {

- ##
- # String Translation::getLocaleCharset()
- #
- # Return the character set for the current system's locale.
- # The return value is guaranteed to be a valid character set name.
