This module is rated as beta, and is ready for widespread use. It is still new and should be used with some caution to ensure the results are as expected.
This module is used by {{Wikt-lang}}. It is inspired by the templates {{m}} and {{l}} and their associated modules on Wiktionary. It has a Wiktionary link function that links to the correct section of the Wiktionary entry, and applies correct language formatting and italics. The language-tagging function does most of what {{Lang}} does, except that italics can't be customized and categories aren't added.
The module uses Module:Wikt-lang/data to retrieve the language name for a language code, and to perform the necessary entry-name replacements (for instance, removing macrons from Latin entry names). These are unfortunately not automatically retrieved from Wiktionary's Wikt-lang data modules. For language codes that do not have a name value in this module, the language name is fetched with mw.language.fetchLanguage. When mw.language.fetchLanguage does not fetch the correct language name (or any language name at all), please add it to Module:Wikt-lang/data, and similarly when the correct entry name is not generated, please add the entry name replacements to the module.

Retrieves the language name.
A langauge is first searched in Module:Wikt-lang/data and if found and has a language name set, returns it.

If no language is found or the language does not have a language name set, returns the language name from Module:Lang/data.

Creates a Wiktionary link.
A link_text, display_text and language_code are always needed. Error if they are missing.
A language name can sometimes be nil if the private code is only listed at Module:Wikt-lang/data and not on Module:Lang/data.
If a language name cannot be retrieved, an erorr is returned.
