Module:script utilities

Purpose

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.

Data is found in Module:script utilities/data.

Exported functions

lang_t

{{#invoke:script utilities|lang_t}}

This is used by {{lang}} to wrap portions of text in a language tag. See there for more information.

tag_text

tag_text(text, lang, sc, face, class)

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>.

"hypothetical"

The text is wrapped in <span class="hypothetical-star">*</span><i class="(sc) hypothetical" lang="(lang)">...</i>.

"bold"

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

nil

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

The optional class parameter can be used to specify an additional CSS class to be added to the tag.

tag_translit

tag_translit(translit, lang, kind, attributes)

Tags the transliteration for given text translit and language lang. It will add the language, script subtag (as defined in BCP 47 2.2.3) and dir (directional) attributes as needed.

The optional kind parameter can be one of the following:

"term"

tag transliteration for {{mention}}

"usex"

tag transliteration for {{usex}}

"head"

tag transliteration for {{head}}

"default"

default

The optional attributes parameter is used to specify additional HTML attributes for the tag.

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.
