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 <i class="(sc) mention" lang="(lang)">...</i>.

"head"

The text is wrapped in <strong class="(sc) headword" lang="(lang)">...</strong>.

"bold"

The text is wrapped in <b class="(sc)" lang="(lang)">...</b>.

nil

The text is wrapped in <span class="(sc)" lang="(lang)">...</span>.

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.
