export.getDataModuleName
[вироиш]function export.getDataModuleName(code)
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.
export.getExtraDataModuleName
[вироиш]function export.getExtraDataModuleName(code)
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.
export.makeObject
[вироиш]function export.makeObject(code, data, useRequire, dontCanonicalizeAliases)
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.
export.getByCode
[вироиш]function export.getByCode(code, paramForError, allowEtymLang, allowFamily, useRequire)
Finds the language whose code matches the one provided. If it exists, it returns a Language
object representing the language. 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. If allowEtymLang
is specified, etymology-only language codes are allowed and looked up along with normal language codes. If allowFamily
is specified, language family codes are allowed and looked up along with normal language codes.
export.getByCanonicalName
[вироиш]function export.getByCanonicalName(name, errorIfInvalid, allowEtymLang, allowFamily, useRequire)
Finds the language whose canonical name (the name used to represent that language on Wiktionary) or other name matches the one provided. If it exists, it returns a Language
object representing the language. Otherwise, it returns nil
, unless paramForError
is given, in which case an error is generated. If allowEtymLang
is specified, etymology-only language codes are allowed and looked up along with normal language codes. If allowFamily
is specified, language family codes are allowed and looked up along with normal language codes.
The canonical name of languages should always be unique (it is an error for two languages on Wiktionary to share the same canonical name), so this is guaranteed to give at most one result.
This function is powered by Module:languages/canonical names, which contains a pre-generated mapping of full-language canonical names to codes. It is generated by going through the Category:Language data modules for full languages. When allowEtymLang
is specified for the above function, Module:etymology languages/canonical names may also be used, and when allowFamily
is specified for the above function, Module:families/canonical names may also be used.
export.addDefaultTypes
[вироиш]function export.addDefaultTypes(data, regular, ...)
Used by Module:languages/data/2 (et al.) to add default types to the entities returned.
export.finalizeLanguageData
[вироиш]function export.finalizeLanguageData(data)
Used by Module:languages/data/2 (et al.) and Module:etymology languages/data to finalize language-related data into the format that is actually returned.
export.finalizeEtymologyData
[вироиш]function export.finalizeEtymologyData(data)
Used by Module:etymology languages/data and Module:families/data/etymology to finalize etymology-related data into the format that is actually returned.
export.err
[вироиш]function export.err(lang_code, param, code_desc, template_tag, not_real_lang)
For backwards compatibility only; modules should require the error themselves.
Объектҳои забонӣ
[вироиш]Объекти Забон
аз яке аз функсияҳои дар боло овардашуда баргардонида мешавад. Ин муаррифии Луа аз забон ва маълумоти бо он алоқаманд аст. Он дорои як қатор усулҳое мебошад, ки онҳоро бо истифода аз синтаксиси :
даъват кардан мумкин аст. Барои намуна:
local m_languages = require("Module:languages")
local lang = m_languages.getByCode("fr")
local name = lang:getCanonicalName()
-- "name" will now be "French"
Language:loadData
[вироиш]function Language:loadData(modname)
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.
Language:getCode
[вироиш]function Language:getCode()
Returns the language code of the language. Example: "fr"
for French.
Language:getCanonicalName
[вироиш]function Language:getCanonicalName()
Returns the canonical name of the language. This is the name used to represent that language on Wiktionary, and is guaranteed to be unique to that language alone. Example: "French"
for French.
Language:getDisplayForm
[вироиш]function Language:getDisplayForm()
Return the display form of the language. The display form of a language, family or script is the form it takes when
appearing as the source
in categories such as English terms derived from
source
or English given names from source
, and is also the displayed text
in makeCategoryLink()
links. For full and etymology-only languages, this is the same as the canonical name, but
for families, it reads "name languages"
(e.g. "Indo-Iranian languages"
), and for scripts,
it reads "name script"
(e.g. "Arabic script"
).
Language:getHTMLAttribute
[вироиш]function Language:getHTMLAttribute(sc, region)
Returns the value which should be used in the HTML lang= attribute for tagged text in the language.
Language:getOtherNames
[вироиш]function Language:getOtherNames(onlyOtherNames)
Returns a table of the "other names" that the language is known by, excluding the canonical name. The names are not guaranteed to be unique, in that sometimes more than one language is known by the same name. Example: {"Manx Gaelic", "Northern Manx", "Southern Manx"}
for Manx. If onlyOtherNames
is given and is non-nil
, only names explicitly listed in the otherNames
field are returned; otherwise, names listed under otherNames
, aliases
and varieties
are combined together and returned. For example, for Manx, Manx Gaelic is listed as an alias, while Northern Manx and Southern Manx are listed as varieties. It should be noted that the otherNames
field itself is deprecated, and entries listed there should eventually be moved to either aliases
or varieties
.
Language:getAliases
[вироиш]function Language:getAliases()
Returns a table of the aliases that the language is known by, excluding the canonical name. Aliases are synonyms for the language in question. The names are not guaranteed to be unique, in that sometimes more than one language is known by the same name. Example: {"High German", "New High German", "Deutsch"}
for German.
Language:getVarieties
[вироиш]function Language:getVarieties(flatten)
Return a table of the known subvarieties of a given language, excluding subvarieties that have been given
explicit etymology-only language codes. The names are not guaranteed to be unique, in that sometimes a given name
refers to a subvariety of more than one language. Example: {"Southern Aymara", "Central Aymara"}
for
Aymara. Note that the returned value can have nested tables in it, when a subvariety
goes by more than one name. Example: {"North Azerbaijani", "South Azerbaijani", {"Afshar", "Afshari", "Afshar Azerbaijani", "Afchar"}, {"Qashqa'i", "Qashqai", "Kashkay"}, "Sonqor"}
for
Azerbaijani. Here, for example, Afshar, Afshari, Afshar Azerbaijani and Afchar
all refer to the same subvariety, whose preferred name is Afshar (the one listed first). To avoid a return value
with nested tables in it, specify a non-nil
value for the flatten
parameter; in that case,
the return value would be {"North Azerbaijani", "South Azerbaijani", "Afshar", "Afshari", "Afshar Azerbaijani", "Afchar", "Qashqa'i", "Qashqai", "Kashkay", "Sonqor"}
.
Language:getTypes
[вироиш]function Language:getTypes()
Returns a table of types as a lookup table (with the types as keys).
The possible types are
language
: This is a language, either full or etymology-only.full
: This is a "full" (not etymology-only) language, i.e. the union ofregular
,reconstructed
and
appendix-constructed
. Note that the types full
and etymology-only
also exist for families, so if you
want to check specifically for a full language and you have an object that might be a family, you should
use hasType("language", "full")
and not simply hasType("full")
.
etymology-only
: This is an etymology-only (not full) language, whose parent is another etymology-only
language or a full language. Note that the types full
and etymology-only
also exist for
families, so if you want to check specifically for an etymology-only language and you have an
object that might be a family, you should use hasType("language", "etymology-only")
and not simply hasType("etymology-only")
.
regular
: This indicates a full language that is attested according to WT:CFI and therefore permitted
in the main namespace. There may also be reconstructed terms for the language, which are placed in
the Reconstruction
namespace and must be prefixed with * to indicate a reconstruction. Most full
languages are natural (not constructed) languages, but a few constructed languages (e.g. Esperanto
and Volapük, among others) are also allowed in the mainspace and considered regular languages.
reconstructed
: This language is not attested according to WT:CFI, and therefore is allowed only in the
Reconstruction
namespace. All terms in this language are reconstructed, and must be prefixed
with *. Languages such as Proto-Indo-European and Proto-Germanic are in this category.
appendix-constructed
: This language is attested but does not meet the additional requirements set out for
constructed languages (WT:CFI#Constructed languages). Its entries must therefore
be in the Appendix namespace, but they are not reconstructed and therefore should
not have * prefixed in links.
Language:hasType
[вироиш]function Language:hasType(...)
Given a list of types as strings, returns true if the language has all of them.
Language:getWikimediaLanguages
[вироиш]function Language:getWikimediaLanguages()
Returns a table containing WikimediaLanguage
objects (see Module:wikimedia languages), which represent languages and their codes as they are used in Wikimedia projects for interwiki linking and such. More than one object may be returned, as a single Wiktionary language may correspond to multiple Wikimedia languages. For example, Wiktionary's single code sh
(Serbo-Croatian) maps to four Wikimedia codes: sh
(Serbo-Croatian), bs
(Bosnian), hr
(Croatian) and sr
(Serbian).
The code for the Wikimedia language is retrieved from the wikimedia_codes
property in the data modules. If that property is not present, the code of the current language is used. If none of the available codes is actually a valid Wikimedia code, an empty table is returned.
Language:getWikimediaLanguageCodes
[вироиш]function Language:getWikimediaLanguageCodes()
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.
Language:getWikipediaArticle
[вироиш]function Language:getWikipediaArticle(noCategoryFallback, project)
Returns the name of the Wikipedia article for the language. `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 language's category, but this won't normally happen for any other project.
Language:makeWikipediaLink
[вироиш]function Language:makeWikipediaLink()
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.
Language:getWikidataItem
[вироиш]function Language:getWikidataItem()
Returns the Wikidata item id for the language or nil
. This corresponds to the the second field in the data modules.
Language:getScripts
[вироиш]function Language:getScripts()
Returns a table of Script
objects for all scripts that the language is written in. See Module:scripts.
Language:getScriptCodes
[вироиш]function Language:getScriptCodes()
Returns the table of script codes in the language's data file.
Language:findBestScript
[вироиш]function Language:findBestScript(text, forceDetect)
Given some text, this function iterates through the scripts of a given language and tries to find the script that best matches the text. It returns a Script
object representing the script. If no match is found at all, it returns the None
script object.
Language:getFamily
[вироиш]function Language:getFamily()
Returns a Family
object for the language family that the language belongs to. See Module:families.
Language:getFamilyCode
[вироиш]function Language:getFamilyCode()
Returns the family code in the language's data file.
Language:getFamilyName
[вироиш]function Language:getFamilyName()
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.
Language:inFamily
[вироиш]function Language:inFamily(...)
Check whether the language belongs to `family` (which can be a family code or object). A list of objects can be given in place of `family`; in that case, return true if the language belongs to any of the specified families. Note that some languages (in particular, certain creoles) can have multiple immediate ancestors potentially belonging to different families; in that case, return true if the language belongs to any of the specified families.
Language:getParent
[вироиш]function Language:getParent()
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.

Language:hasParent
[вироиш]function Language:hasParent(...)
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.
Language:getFull
[вироиш]function Language:getFull()
If the language is etymology-only, this iterates through parents until a full language or family is found, and the
corresponding object is returned. If the language is a full language, then it simply returns itself.
Language:getFullCode
[вироиш]function Language:getFullCode()
If the language is an etymology-only language, this iterates through parents until a full language or family is
found, and the corresponding code is returned. If the language is a full language, then it simply returns the
language code.
Language:getFullName
[вироиш]function Language:getFullName()
If the language is an etymology-only language, this iterates through parents until a full language or family is
found, and the corresponding canonical name is returned. If the language is a full language, then it simply returns
the canonical name of the language.
Language:getAncestors
[вироиш]function Language:getAncestors()
Returns a table of Language
objects for all languages that this language is directly descended from. Generally this is only a single language, but creoles, pidgins and mixed languages can have multiple ancestors.
Language:getAncestorCodes
[вироиш]function Language:getAncestorCodes()
Returns a table of Language
codes for all languages that this language is directly descended from. Generally this is only a single language, but creoles, pidgins and mixed languages can have multiple ancestors.
Language:hasAncestor
[вироиш]function Language:hasAncestor(...)
Given a list of language objects or codes, returns true if at least one of them is an ancestor. This includes any etymology-only children of that ancestor. If the language's ancestor(s) are etymology-only languages, it will also return true for those language parent(s) (e.g. if Vulgar Latin is the ancestor, it will also return true for its parent, Latin). However, a parent is excluded from this if the ancestor is also ancestral to that parent (e.g. if Classical Persian is the ancestor, Persian would return false, because Classical Persian is also ancestral to Persian).
Language:getAncestorChain
[вироиш]function Language:getAncestorChain()
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.

Language:hasChild
[вироиш]function Language:hasChild(...)
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.
Language:getCategoryName
[вироиш]function Language:getCategoryName(nocap)
Returns the name of the main category of that language. Example: "French language"
for French, whose category is at Category:French language. Unless optional argument nocap
is given, the language name at the beginning of the returned value will be capitalized. This capitalization is correct for category names, but not if the language name is lowercase and the returned value of this function is used in the middle of a sentence.
Language:makeCategoryLink
[вироиш]function Language:makeCategoryLink()
Creates a link to the category; the link text is the canonical name.
Language:getStandardCharacters
[вироиш]function Language:getStandardCharacters(sc)

Language:makeEntryName
[вироиш]function Language:makeEntryName(text, sc)
Make the entry name (i.e. the correct page name).
Language:generateForms
[вироиш]function Language:generateForms(text, sc)
Generates alternative forms using a specified method, and returns them as a table. If no method is specified, returns a table containing only the input term.
Language:makeSortKey
[вироиш]function Language:makeSortKey(text, sc)
Creates a sort key for the given entry name, following the rules appropriate for the language. This removes diacritical marks from the entry name if they are not considered significant for sorting, and may perform some other changes. Any initial hyphen is also removed, and anything parentheses is removed as well.
The sort_key
setting for each language in the data modules defines the replacements made by this function, or it gives the name of the module that takes the entry name and returns a sortkey.
Language:makeDisplayText
[вироиш]function Language:makeDisplayText(text, sc, keepPrefixes)
Make the display text (i.e. what is displayed on the page).
Language:transliterate
[вироиш]function Language:transliterate(text, sc, module_override)
Transliterates the text from the given script into the Latin script (see Wiktionary:Transliteration and romanization). The language must have the translit
property for this to work; if it is not present, nil
is returned.
Returns three values:
- The transliteration.
- A boolean which indicates whether the transliteration failed for an unexpected reason. If
false
, then the transliteration either succeeded, or the module is returning nothing in a controlled way (e.g. the input was"-"
). Generally, this means that no maintenance action is required. Iftrue
, then the transliteration isnil
because either the input or output was defective in some way (e.g. Module:ar-translit will not transliterate non-vocalised inputs, and this module will fail partially-completed transliterations in all languages). Note that this value can be manually set by the transliteration module, so make sure to cross-check to ensure it is accurate. - A table of categories selected by the transliteration module, which should be in the format expected by
format_categories
in Module:utilities.
The sc
parameter is handled by the transliteration module, and how it is handled is specific to that module. Some transliteration modules may tolerate nil
as the script, others require it to be one of the possible scripts that the module can transliterate, and will show an error if it's not one of them. For this reason, the sc
parameter should always be provided when writing non-language-specific code.
The module_override
parameter is used to override the default module that is used to provide the transliteration. This is useful in cases where you need to demonstrate a particular module in use, but there is no default module yet, or you want to demonstrate an alternative version of a transliteration module before making it official. It should not be used in real modules or templates, only for testing. All uses of this parameter are tracked by Wiktionary:Tracking/module_override.
Known bugs:
- This function assumes
tr(s1) .. tr(s2) == tr(s1 .. s2)
. When this assertion fails, wikitext markups like ''' can cause wrong transliterations. - HTML entities like
'
, often used to escape wikitext markups, do not work.
Language:overrideManualTranslit
[вироиш]function Language:overrideManualTranslit(sc)
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.
Language:link_tr
[вироиш]function Language:link_tr(sc)
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.
Language:hasTranslit
[вироиш]function Language:hasTranslit()
Returns true
if the language has a transliteration module, or false
if it doesn't.
Language:hasDottedDotlessI
[вироиш]function Language:hasDottedDotlessI()
Returns true
if the language uses the letters I/ı and İ/i, or false
if it doesn't.
Language:toJSON
[вироиш]function Language:toJSON(returnTable)
This function lacks documentation. Please add a description of its usages, inputs and outputs, or its difference from similar functions, or make it local to remove it from the function list.
Language:getRawData
[вироиш]function Language:getRawData()
This function is not for use in entries or other content pages.
Returns a blob of data about the language. The format of this blob is undocumented, and perhaps unstable; it's intended for things like the module's own unit-tests, which are "close friends" with the module and will be kept up-to-date as the format changes.
-- Do NOT use these methods!
-- All uses should be pre-approved on the talk page!
Language:getRawExtraData
[вироиш]function Language:getRawExtraData()
This function is not for use in entries or other content pages.
Returns a blob of data about the language that contains the "extra data". Much like with getRawData, the format of this blob is undocumented, and perhaps unstable; it's intended for things like the module's own unit-tests, which are "close friends" with the module and will be kept up-to-date as the format changes.
Language:loadInExtraData
[вироиш]function Language:loadInExtraData()

This module implements fetching of language-specific information and processing text in a given language.
There are two types of languages: full languages and etymology-only languages. The essential difference is that only
full languages appear in L2 headings in vocabulary entries, and hence categories like [[:Category:French nouns]] exist
only for full languages. Etymology-only languages have either a full language or another etymology-only language as
their parent (in the parent-child inheritance sense), and for etymology-only languages with another etymology-only
language as their parent, a full language can always be derived by following the parent links upwards. For example,
"Canadian French", code 'fr-CA', is an etymology-only language whose parent is the full language "French", code 'fr'.
An example of an etymology-only language with another etymology-only parent is "Northumbrian Old English", code
'ang-nor', which has "Anglian Old English", code 'ang-ang' as its parent; this is an etymology-only language whose
parent is "Old English", code "ang", which is a full language. (This is because Northumbrian Old English is considered
a variety of Anglian Old English.) Sometimes the parent is the "Undetermined" language, code 'und'; this is the case,
for example, for "substrate" languages such as "Pre-Greek", code 'qsb-grc', and "the BMAC substrate", code 'qsb-bma'.
It is important to distinguish language ''parents'' from language ''ancestors''. The parent-child relationship is one
of containment, i.e. if X is a child of Y, X is considered a variety of Y. On the other hand, the ancestor-descendant
relationship is one of descent in time. For example, "Classical Latin", code 'la-cla', and "Late Latin", code 'la-lat',
are both etymology-only languages with "Latin", code 'la', as their parents, because both of the former are varieties
of Latin. However, Late Latin does *NOT* have Classical Latin as its parent because Late Latin is *not* a variety of
Classical Latin; rather, it is a descendant. There is in fact a separate 'ancestors' field that is used to express the
ancestor-descendant relationship, and Late Latin's ancestor is given as Classical Latin. It is also important to note
that sometimes an etymology-only language is actually the conceptual ancestor of its parent language. This happens,
for example, with "Old Italian" (code 'roa-oit'), which is an etymology-only variant of full language "Italian" (code
'it'), and with "Old Latin" (code 'itc-ola'), which is an etymology-only variant of Latin. In both cases, the full
language has the etymology-only variant listed as an ancestor. This allows a Latin term to inherit from Old Latin
using the {{tl|inh}} template (where in this template, "inheritance" refers to ancestral inheritance, i.e. inheritance
in time, rather than in the parent-child sense); likewise for Italian and Old Italian.
Full languages come in three subtypes:
* {regular}: This indicates a full language that is attested according to [[WT:CFI]] and therefore permitted in the
main namespace. There may also be reconstructed terms for the language, which are placed in the
{Reconstruction} namespace and must be prefixed with * to indicate a reconstruction. Most full languages
are natural (not constructed) languages, but a few constructed languages (e.g. Esperanto and Volapük,
among others) are also allowed in the mainspace and considered regular languages.
* {reconstructed}: This language is not attested according to [[WT:CFI]], and therefore is allowed only in the
{Reconstruction} namespace. All terms in this language are reconstructed, and must be prefixed with
*. Languages such as Proto-Indo-European and Proto-Germanic are in this category.
* {appendix-constructed}: This language is attested but does not meet the additional requirements set out for
constructed languages ([[WT:CFI#Constructed languages]]). Its entries must therefore be in
the Appendix namespace, but they are not reconstructed and therefore should not have *
prefixed in links. Most constructed languages are of this subtype.
Both full languages and etymology-only languages have a {Language} object associated with them, which is fetched using
the {getByCode} function in [[Module:languages]] to convert a language code to a {Language} object. Depending on the
options supplied to this function, etymology-only languages may or may not be accepted, and family codes may be
accepted (returning a {Family} object as described in [[Module:families]]). There are also separate {getByCanonicalName}
functions in [[Module:languages]] and [[Module:etymology languages]] to convert a language's canonical name to a
{Language} object (depending on whether the canonical name refers to a full or etymology-only language).
Textual strings belonging to a given language come in several different ''text variants'':
# The ''input text'' is what the user supplies in wikitext, in the parameters to {{tl|m}}, {{tl|l}}, {{tl|ux}},
{{tl|t}}, {{tl|lang}} and the like.
# The ''display text'' is the text in the form as it will be displayed to the user. This can include accent marks that
are stripped to form the entry text (see below), as well as embedded bracketed links that are variously processed
further. The display text is generated from the input text by applying language-specific transformations; for most
languages, there will be no such transformations. Examples of transformations are bad-character replacements for
certain languages (e.g. replacing 'l' or '1' to [[palochka]] in certain languages in Cyrillic); and for Thai and
Khmer, converting space-separated words to bracketed words and resolving respelling substitutions such as [กรีน/กฺรีน],
which indicate how to transliterate given words.
# The ''entry text'' is the text in the form used to generate a link to a Wiktionary entry. This is usually generated
from the display text by stripping certain sorts of diacritics on a per-language basis, and sometimes doing other
transformations. The concept of ''entry text'' only really makes sense for text that does not contain embedded links,
meaning that display text containing embedded links will need to have the links individually processed to get
per-link entry text in order to generate the resolved display text (see below).
# The ''resolved display text'' is the result of resolving embedded links in the display text (e.g. converting them to
two-part links where the first part has entry-text transformations applied, and adding appropriate language-specific
fragments) and adding appropriate language and script tagging. This text can be passed directly to MediaWiki for
display.
# The ''source translit text'' is the text as supplied to the language-specific {transliterate()} method. The form of
the source translit text may need to be language-specific, e.g Thai and Khmer will need the full unprocessed input
text, whereas other languages may need to work off the display text. [FIXME: It's still unclear to me how embedded
bracketed links are handled in the existing code.] In general, embedded links need to be removed (i.e. converted to
their "bare display" form by taking the right part of two-part links and removing double brackets), but when this
happens is unclear to me [FIXME]. Some languages have a chop-up-and-paste-together scheme that sends parts of the
text through the transliterate mechanism, and for others (those listed in {contiguous_substition} in
[[Module:languages/data]]) they receive the full input text, but preprocessed in certain ways. (The wisdom of this is
still unclear to me.)
# The ''transliterated text'' (or ''transliteration'') is the result of transliterating the source translit text.
Unlike for all the other text variants except the transcribed text, it is always in the Latin script.
# The ''transcribed text'' (or ''transcription'') is the result of transcribing the source translit text, where
"transcription" here means a close approximation to the phonetic form of the language in languages (e.g. Akkadian,
Sumerian, Ancient Egyptian, maybe Tibetan) that have a wide difference between the written letters and spoken form.
Unlike for all the other text variants other than the transliterated text, it is always in the Latin script.
Currently, the transcribed text is always supplied manually be the user; there is no such thing as a
{lua|transcribe()} method on language objects.
# The ''sort key'' is the text used in sort keys for determining the placing of pages in categories they belong to. The
sort key is generated from the pagename or a specified ''sort base'' by lowercasing, doing language-specific
transformations and then uppercasing the result. If the sort base is supplied and is generated from input text, it
needs to be converted to display text, have embedded links removed (i.e. resolving them to their right side if they
are two-part links) and have entry text transformations applied.
# There are other text variants that occur in usexes (specifically, there are normalized variants of several of the
above text variants), but we can skip them for now.
The following methods exist on {Language} objects to convert between different text variants:
# {makeDisplayText}: This converts input text to display text.
# {lua|makeEntryName}: This converts input or display text to entry text. [FIXME: This needs some rethinking. In
particular, {lua|makeEntryName} is sometimes called on display text (in some paths inside of [[Module:links]]) and
sometimes called on input text (in other paths inside of [[Module:links]], and usually from other modules). We need
to make sure we don't try to convert input text to display text twice, but at the same time we need to support
calling it directly on input text since so many modules do this. This means we need to add a parameter indicating
whether the passed-in text is input or display text; if that former, we call {lua|makeDisplayText} ourselves.]
# {lua|transliterate}: This appears to convert input text with embedded brackets removed into a transliteration.
[FIXME: This needs some rethinking. In particular, it calls {lua|processDisplayText} on its input, which won't work
for Thai and Khmer, so we may need language-specific flags indicating whether to pass the input text directly to the
language transliterate method. In addition, I'm not sure how embedded links are handled in the existing translit code;
a lot of callers remove the links themselves before calling {lua|transliterate()}, which I assume is wrong.]
# {lua|makeSortKey}: This converts entry text (?) to a sort key. [FIXME: Clarify this.]

--[==[Transliterates the text from the given script into the Latin script (see [[Wiktionary:Transliteration and romanization]]). The language must have the <code>translit</code> property for this to work; if it is not present, {{code|lua|nil}} is returned.
Returns three values:
# The transliteration.
# A boolean which indicates whether the transliteration failed for an unexpected reason. If {{code|lua|false}}, then the transliteration either succeeded, or the module is returning nothing in a controlled way (e.g. the input was {{code|lua|"-"}}). Generally, this means that no maintenance action is required. If {{code|lua|true}}, then the transliteration is {{code|lua|nil}} because either the input or output was defective in some way (e.g. [[Module:ar-translit]] will not transliterate non-vocalised inputs, and this module will fail partially-completed transliterations in all languages). Note that this value can be manually set by the transliteration module, so make sure to cross-check to ensure it is accurate.
# A table of categories selected by the transliteration module, which should be in the format expected by {{code|lua|format_categories}} in [[Module:utilities]].
The <code>sc</code> parameter is handled by the transliteration module, and how it is handled is specific to that module. Some transliteration modules may tolerate {{code|lua|nil}} as the script, others require it to be one of the possible scripts that the module can transliterate, and will show an error if it's not one of them. For this reason, the <code>sc</code> parameter should always be provided when writing non-language-specific code.
The <code>module_override</code> parameter is used to override the default module that is used to provide the transliteration. This is useful in cases where you need to demonstrate a particular module in use, but there is no default module yet, or you want to demonstrate an alternative version of a transliteration module before making it official. It should not be used in real modules or templates, only for testing. All uses of this parameter are tracked by [[Wiktionary:Tracking/module_override]].
'''Known bugs''':
* This function assumes {tr(s1) .. tr(s2) == tr(s1 .. s2)}. When this assertion fails, wikitext markups like <nowiki>'''</nowiki> can cause wrong transliterations.
* HTML entities like <code>&apos;</code>, often used to escape wikitext markups, do not work.]==]
