NAME

EPrints::Language - A Single Language supported by a repository.

DESCRIPTION

The language class handles loading the "phrase" files for a single language. See the mail documentation for a full explanation of the format of phrase files.

METHODS

new

$language = EPrints::Language->new( $langid, $repository, [$fallback] )

Create a new language object representing the phases eprints will use in a given language, loading them from the phrase config XML files.

$langid is the ISO language ID of the language, $repository is the repository to which this language object belongs. $fallback is either undef or a reference to the main language object for the repository.

get_phrase_info

$info = $lang->get_phrase_info( $phraseid )

Returns a hash describing the phrase $phraseid. Contains:

  langid - the language the phrase is from
  phraseid - the phrase id
  xml - the raw XML fragment
  fallback - whether the phrase was from the fallback language
  system - whether the phrase was from the system files
  filename - the file the phrase came from

If $phraseid doesn't exist returns undef.

get_phrase_ids

$phraseids = $language->get_phrase_ids( $fallback )

Return a reference to an array of all phrase ids that are defined in this language (repository and system).

If $fallback is true returns any additional phrase ids defined in the fallback language.

phrase

$xhtml = $language->phrase( $phraseid, $inserts )

Return an XHTML DOM structure for the phrase with the given phraseid.

The phraseid is looked for in the following order, if it's not in one phrase file the system checks the next.

• This languages repository specific phrases.
• The fallback languages repository specific phrases (if there is a fallback).
• This languages general phrases.
• The fallback languages general phrases (if there is a fallback).
• Failing that it returns an XHTML DOM encoded error.

If the phrase contains "pin" elements then $inserts must be a reference to a hash. Each "pin" has a "name" attribute. For each pin there must be a key in $inserts of the "name". The value is a XHTML DOM object which will replace the "pin" when returing this phrase.

has_phrase

$boolean = $language->has_phrase( $phraseid )

Return 1 if the phraseid is defined for this language. Return 0 if it is only available as a fallback or unavailable.

get_id

$langid = $language->get_id

Return the ISO language ID of this language object.

get_fallback

$lang = $language->get_fallback()

Return the fallback language for this language. Returns undef if there is no fallback.

load_phrases

$ok = $language->load_phrases( $file )

Load phrases from $file into the current language (use with care!).

create_phrase_doc

$doc = EPrints::Language->create_phrase_doc( $session, [ $comment ] )

Create and return a new, empty, phrases document. Optionally put $comment at the top.
