I18n library for message storage in Lua datastores. The module is designed to enable message separation from modules & templates. It has support for handling language fallbacks. This module is a Lua port of wikia:dev:I18n-js and i18n modules that can be loaded by it are editable through wikia:dev:I18nEdit.

Package items

i18n.getMsg(frame) (function)

Localized message getter by key. Can be used to fetch messages in a specific language code through uselang parameter. Extra numbered parameters can be supplied for substitution into the datastore message.

Parameters:

frame Frame table from invocation. (table)

frame.args Metatable containing arguments. (table)

frame.args[1] ROOTPAGENAME of i18n submodule. (string)

frame.args[2] Key of i18n message. (string)

frame.args.lang Default language of message. (string; optional)

Error: 'missing arguments in i18n.getMsg' (line 271)

Returns: I18n message in localised language. (string)

Usage: {{i18n}}

i18n.loadMessages(...) (function)

I18n message datastore loader.

Parameter: ... ROOTPAGENAME/path for target i18n submodules. (string)

Error: 'no source supplied to i18n.loadMessages' (string; line 322)

Returns: I18n datastore instance. (table)

Usage: require('Module:I18n').loadMessages('1', '2')

i18n.getLang() (function)

Language code getter. Can validate a template's language code through uselang parameter.

Returns: Language code. (string)

Usage: {{i18n}}

i18n.main(frame) (function)

Template wrapper for Template:I18n.

Parameter: frame Frame invocation object. (table)

Returns: Module output in template context. (string)

Usage: {{i18n}}

_i18n.isWikitext(msg) (function)

Checks whether a message contains unprocessed wikitext. Used to optimise message getter by not preprocessing pure text.

Parameter: msg Message to check. (string)

Returns: Whether the message contains wikitext. (boolean)

`Data`

I18n datastore class. This is used to control language translation and access to individual messages. The datastore instance provides language and message getter-setter methods, which can be used to internationalize Lua modules. The language methods (any ending in Lang) are all chainable.

Data:msg(opts, ...) (function)

Datastore message getter utility. This method returns localized messages from the datastore corresponding to a key. These messages may have $n parameters, which can be replaced by optional argument strings supplied by the msg call.

This function supports named arguments. The named argument syntax is more versatile despite its verbosity; it can be used to select message language & source(s).

Parameters:

opts Message configuration or key. (string|table)

opts.key Message key to return from the datastore. (string; optional)

opts.args Arguments to substitute into the message ($n). (table; optional)

opts.sources Source names to limit to (see Data:fromSources). (table; optional)

opts.lang Temporary language to use (see Data:inLang). (table; optional)

... Arguments to substitute into the message ($n). (string; optional)

Error: 'missing arguments in Data:msg' (string; line 115)

Returns: Localised datastore message or '<key>'. (string)

Usage:

ds:msg{
    key = 'message-name',
    lang = '',
    args = {...},
    sources = {}
}

ds:msg('message-name', ...)

Data:parameter(parameter, args) (function)

Datastore template parameter getter utility. This method, given a table of arguments, tries to find a parameter's localized name in the datastore and returns its value, or nil if not present. This method always uses the wiki's content language.

Parameters:

parameter Parameter's key in the datastore (string)

args Arguments to find the parameter in (table)

Error: 'missing arguments in Data:parameter' (string; line 176)

Returns: Parameter's value or nil if not present (string|nil)

Data:fromSource(...) (function)

Datastore temporary source setter to a specificed subset of datastores. By default, messages are fetched from the datastore in the same order of priority as i18n.loadMessages.

Parameter: ... Source name(s) to use. (string)
