This module is used to retrieve and manage Wiktionary's various writing systems and the information associated with them. See Wiktionary:Scripts for more information.

The information itself is stored in Module:scripts/data. The data module should not be used directly by any other module, the data should only be accessed through the functions provided by Module:scripts.

For functions that allow templates to use this module, see Module:scripts/templates.

Finding and retrieving scripts

The module exports a number of functions that are used to find scripts.

export.makeObject

function export.makeObject(code, raw_data)

export.getByCode

function export.getByCode(code, paramForError, disallowNil)

Finds the script whose code matches the one provided. If it exists, it returns a Script object representing the script. Otherwise, it returns nil, unless paramForError is given, in which case an error is generated. If paramForError is true, a generic error message mentioning the bad code is generated; otherwise paramForError should be a string or number specifying the parameter that the code came from, and this parameter will be mentioned in the error message along with the bad code.

export.getByCanonicalName

function export.getByCanonicalName(name)

export.charToScript

function export.charToScript(char)

Takes a codepoint or a character and finds the script code (if any) that is

appropriate for it based on the codepoint, using the data module

Module:scripts/recognition data. The data module was generated from the

patterns in Module:scripts/data using Module:User:Erutuon/script recognition.

Converts the character to a codepoint. Returns a script code if the codepoint

is in the list of individual characters, or if it is in one of the defined

ranges in the 4096-character block that it belongs to, else returns "None".

export.findBestScriptWithoutLang

function export.findBestScriptWithoutLang(text, none_is_last_resort_only)

Returns the code for the script that has the greatest number of characters in `text`. Useful for script tagging text

that is unspecified for language. Uses Module:scripts/recognition data to determine a script code for a character

language-agnostically. Specifically, it works as follows:

Convert each character to a codepoint. Increment the counter for the script code if the codepoint is in the list

of individual characters, or if it is in one of the defined ranges in the 4096-character block that it belongs to.

Each script has a two-part counter, for primary and secondary matches. Primary matches are when the script is the

first one listed; otherwise, it's a secondary match. When comparing scripts, first the total of both are compared

(i.e. the overall number of matches). If these are the same, the number of primary and then secondary matches are

used as tiebreakers. For example, this is used to ensure that `Grek` takes priority over `Polyt` if no characters

which exclusively match `Polyt` are found, as `Grek` is a subset of `Polyt`.

If `none_is_last_resort_only` is specified, this will never return "None" if any characters in `text` belong to a

script. Otherwise, it will return "None" if there are more characters that don't belong to a script than belong to

any individual script. (FIXME: This behavior is probably wrong, and `none_is_last_resort_only` should probably

become the default.)

Script objects

A Script object is returned from one of the functions above. It is a Lua representation of a script and the data associated with it. It has a number of methods that can be called on it, using the : syntax. For example:

local m_scripts = require("Module:scripts")
local sc = m_scripts.getByCode("Latn")
local name = sc:getCanonicalName()
-- "name" will now be "Latin"

Script:getCode

function Script:getCode()

Returns the script code of the script. Example: "Cyrl" for Cyrillic.

Script:getCanonicalName

function Script:getCanonicalName()

Returns the canonical name of the script. This is the name used to represent that script on Wiktionary. Example: "Cyrillic" for Cyrillic.

Script:getDisplayForm

function Script:getDisplayForm()

Returns the display form of the script. For scripts, this is the same as the value returned by :getCategoryName("nocap"), i.e. it reads "NAME script" (e.g. "Arabic script"). The displayed text used in :makeCategoryLink is always the same as the display form.

Script:getOtherNames

function Script:getOtherNames(onlyOtherNames)

Script:getAliases

function Script:getAliases()

Script:getVarieties

function Script:getVarieties(flatten)

Script:getIETFSubtag

function Script:getIETFSubtag()

Returns the IETF subtag used for the script, which should always be a valid ISO 15924 script code. This is used when constructing HTML lang= tags. The ietf_subtag value from the script's data file is used, if present; otherwise, the script code is used. For script codes which contain a hyphen, only the part after the hyphen is used (e.g. "fa-Arab" becomes "Arab").

Script:getParent

function Script:getParent()

Returns the parent of the script. Example: "Arab" for "fa-Arab". It returns "top" for scripts without a parent, like "Latn", "Grek", etc.

Script:getSystemCodes

function Script:getSystemCodes()

Script:getSystems

function Script:getSystems()

Script:isSystem

function Script:isSystem(...)

Check whether the script is of type `system`, which can be a writing system code or object. If multiple systems are passed, return true if the script is any of the specified systems.

Script:hasType

function Script:hasType(...)

Given a list of types as strings, returns true if the script has all of them.

Currently the only possible type is script; use hasType("script") to determine if an object that

may be a language, family or script is a script.

Script:getCategoryName

function Script:getCategoryName(nocap)

Returns the name of the main category of that script. Example: "Cyrillic script" for Cyrillic, whose category is at Category:Cyrillic script.

Unless optional argument nocap is given, the script name at the beginning of the returned value will be capitalized. This capitalization is correct for category names, but not if the script name is lowercase and the returned value of this function is used in the middle of a sentence. (For example, the script with the code Semap has the name "flag semaphore", which should remain lowercase when used as part of the category name Category:Translingual letters in flag semaphore but should be capitalized in Category:Flag semaphore templates.) If you are considering using getCategoryName("nocap"), use getDisplayForm() instead.

Script:makeCategoryLink

function Script:makeCategoryLink()

Script:getWikidataItem

function Script:getWikidataItem()

Returns the Wikidata item id for the script or nil. This corresponds to the the second field in the data modules.

Script:getWikipediaArticle

function Script:getWikipediaArticle(noCategoryFallback, project)

Returns the name of the Wikipedia article for the script. `project` specifies the language and project to retrieve

the article from, defaulting to "enwiki" for the English Wikipedia. Normally if specified it should be the project

code for a specific-language Wikipedia e.g. "zhwiki" for the Chinese Wikipedia, but it can be any project, including

non-Wikipedia ones. If the project is the English Wikipedia and the property wikipedia_article is present in the data

module it will be used first. In all other cases, a sitelink will be generated from :getWikidataItem (if set). The

resulting value (or lack of value) is cached so that subsequent calls are fast. If no value could be determined, and

`noCategoryFallback` is false, :getCategoryName is used as fallback; otherwise, nil is returned. Note that if

`noCategoryFallback` is nil or omitted, it defaults to false if the project is the English Wikipedia, otherwise

to true. In other words, under normal circumstances, if the English Wikipedia article couldn't be retrieved, the

return value will fall back to a link to the script's category, but this won't normally happen for any other project.

Script:getCommonsCategory

function Script:getCommonsCategory()

Returns the name of the Wikimedia Commons category page for the script.

Script:getCharacters

function Script:getCharacters()

Returns the charset defining the script's characters from the script's data file.

This can be used to search for words consisting only of this script, but see the warning above.

Script:countCharacters

function Script:countCharacters(text)

Returns the number of characters in the text that are part of this script.

Note: You should never assume that text consists entirely of the same script. Strings may contain spaces, punctuation and even wiki markup or HTML tags. HTML tags will skew the counts, as they contain Latin-script characters. So it's best to avoid them.

Script:hasCapitalization

function Script:hasCapitalization()

Script:hasSpaces

function Script:hasSpaces()

Script:isTransliterated

function Script:isTransliterated()

Script:sortByScraping

function Script:sortByScraping()

Returns true if the script is (sometimes) sorted by scraping page content, meaning that it is sensitive to changes in capitalization during sorting.

Script:getDirection

function Script:getDirection()

Returns the text direction. Horizontal scripts return "ltr" (left-to-right) or "rtl" (right-to-left), while vertical scripts return "vertical-ltr" (vertical left-to-right) or "vertical-rtl" (vertical right-to-left).

Script:getRawData

function Script:getRawData()

Script:hasNormalizationFixes

function Script:hasNormalizationFixes()

Returns true if the script contains characters that require fixes to Unicode normalization under certain circumstances, false if it doesn't.

Script:fixDiscouragedSequences

function Script:fixDiscouragedSequences(text)

Corrects discouraged sequences of Unicode characters to the encouraged equivalents.

Script:toJSON

function Script:toJSON()

--[==[
Returns the code for the script that has the greatest number of characters in `text`. Useful for script tagging text
that is unspecified for language. Uses [[Module:scripts/recognition data]] to determine a script code for a character
language-agnostically. Specifically, it works as follows:
	
Convert each character to a codepoint. Increment the counter for the script code if the codepoint is in the list
of individual characters, or if it is in one of the defined ranges in the 4096-character block that it belongs to.
	
Each script has a two-part counter, for primary and secondary matches. Primary matches are when the script is the
first one listed; otherwise, it's a secondary match. When comparing scripts, first the total of both are compared
(i.e. the overall number of matches). If these are the same, the number of primary and then secondary matches are
used as tiebreakers. For example, this is used to ensure that `Grek` takes priority over `Polyt` if no characters
which exclusively match `Polyt` are found, as `Grek` is a subset of `Polyt`.
	
If `none_is_last_resort_only` is specified, this will never return {"None"} if any characters in `text` belong to a
script. Otherwise, it will return {"None"} if there are more characters that don't belong to a script than belong to
any individual script. (FIXME: This behavior is probably wrong, and `none_is_last_resort_only` should probably
become the default.)
