ମଡ୍ୟୁଲ:script utilities

This module provides access to Module:scripts from templates, so that they can make use of the information stored there. It also provides a number of functions that can be used by other modules.

Exported functions

tag_text

tag_text(text, lang, sc, face)

Wraps the given text in HTML tags with appropriate CSS classes (see WT:CSS) for the language and script. This is required for all non-English text on Wiktionary.

The actual tags and CSS classes that are added are determined by the face parameter. It can be one of the following:

"term": The text is wrapped in ....
"head": The text is wrapped in ....
"bold": The text is wrapped in ....
nil: The text is wrapped in ....

transliterate

transliterate(text, lang, sc)

Generates a transliteration (romanization) from the given text into Latin script, using the transliteration rules of the given language. This will use the module specified with the translit_module setting for the language in Module:languages. If no transliteration module is available, or if the transliteration fails in some other way, nil is returned.

request_script

request_script(lang, sc)

Generates a request to provide a term in its native script, if it is missing. This is used by the {{rfscript}} template as well as by the functions in Module:links.

The function will add entries to one of the subcategories of Category:Terms needing native script by language, and do several checks on the given language and script. In particular:

If the script was given, a subcategory named "needing (script) script" is added, but only if the language has more than one script. Otherwise, the main "needing native script" category is used.
Nothing is added at all if the language has no scripts other than Latin and its varieties.

template_rfscript

{{#invoke:script utilities|template_rfscript}}

This is used by {{rfscript}}. See there for more information.
