NAME

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

User Comments


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.

User Comments


INSTANCE VARIABLES

User Comments


$self->{id}

The ISO ID of this language.

User Comments


$self->{fallback}

If $self is the primary language in its repository then this is undef, otherwise it is a reference to the primary language object.

User Comments


$self->{repository_data}

A reference to a hash. Keys are IDs for phrases, values are DOM fragments containing the phases. Contains repository specific phrases.

User Comments


$self->{data}

A reference to a hash. Keys are IDs for phrases, values are DOM fragments containing the phases. Contains generic eprints phrases.

User Comments


$self->{xmldoc}

A XML document to hold all the stray DOM elements.

User Comments


METHODS

User Comments


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.

User Comments


clone

EPrints::Language->CLONE

Clone a language object.

User Comments


get_phrase_info

$info = $language->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.

User Comments


get_phrase_ids

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

Returns 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.

User Comments


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.

1. This languages repository specific phrases.

2. The fallback languages repository specific phrases (if there is a fallback).

3. This languages general phrases.

4. The fallback languages general phrases (if there is a fallback).

5. 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.

User Comments


has_phrase

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

Returns true if the $phraseid is defined for this language. Returns false if it is only available as a fallback or unavailable.

User Comments


get_id

$langid = $language->get_id

Return the ISO language ID of this language object.

User Comments


get_fallback

$lang = $language->get_fallback

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

User Comments


load_phrases

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

Load phrases from $file into the current language. Use with care!

User Comments


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.
