-- This provides categories and documentation for various data modules, so that -- isn’t unnecessarily cluttered. -- It is a list of tables, each of which have the following possible fields:

-- `regex` (required): A Lua pattern to match the module's title. If it matches, the data in this entry will be used. -- Any captures in the pattern can by referenced in the `cat` field using %1 for the first capture, %2 for the -- second, etc. (often used for creating the sortkey for the category). In addition, the captures are passed to the -- `process` function as the third and subsequent parameters.

-- `process` (optional): This may be a function or a string. If it is a function, it is called as follows: --   process(TITLE, CATS, CAPTURE1, CAPTURE2, ...) -- where: --   * TITLE is a title object describing the module's title; see. --   * CATS is an array object (see Module:array) of categories that the module will be added to. --   * CAPTURE1, CAPTURE2, ... contain any captures in the `regex` field. -- The return value of `process` should be a string and will be used as the module's documentation. -- If `process` is a string, it is the name of a submodule under 'Module:documentation/functions/' which returns a -- function, of the same type as described above. If `process` is omitted entirely, the module will have no -- documentation.

-- `cat` (optional): A string naming the category into which the module should be placed. Captures specified in `regex` -- may be referenced in this string using %1 for the first capture, %2 for the second, etc. Currently, in order to put -- the module into multiple categories, you need to write a `process` function that adds categories to the CATS -- parameter passed in. local module_regex = { {		regex = "^Module:languages/.+$", cat = "Language and script modules", },	{		regex = "^Module:scripts/.+$", cat = "Language and script modules", },	{		regex = "^Module:data tables/data..?.?.?$", cat = "Reference module sharded data tables", },	{		regex = "^Module:Quotations/...?.?.?.?.?.?$", cat = "Quotation data modules", },	{		regex = "^Module:zh/data/dial%-pron/.+$", cat = "Chinese dialectal pronunciation data modules", process = "zh dial or syn", },	{		regex = "^Module:zh/data/dial%-syn/.+$", cat = "Chinese dialectal synonyms data modules", process = "zh dial or syn", },	{		regex = "^Module:zh/data/glyph%-data/.+$", cat = "Chinese historical character forms data modules", process = function(title, cats) local character = title.fullText:match("^Module:zh/data/glyph%-data/(.+)") if character then return ("This module contains data on historical forms of the Chinese character %s.") :format(zh_link(character)) end end, },	{		regex = "^Module:zh/data/ltc%-pron/(.+)$", cat = "Middle Chinese pronunciation data modules|%1", process = "zh data", },	{		regex = "^Module:zh/data/och%-pron%-BS/(.+)$", cat = "Old Chinese (Baxter-Sagart) pronunciation data modules|%1", process = "zh data", },	{		regex = "^Module:zh/data/och%-pron%-ZS/(.+)$", cat = "Old Chinese (Zhengzhang) pronunciation data modules|%1", process = "zh data", },	{		-- capture rest of zh/data submodules regex = "^Module:zh/data/(.+)$", cat = "Chinese data modules|%1", },	{		regex = "^Module:mul/guoxue%-data/cjk%-?(.*)$", process = "guoxue-data", },	{		regex = "^Module:Unicode data/(.+)$", cat = "Unicode data modules|%1", process = make_Unicode_data_documentation, },	{		regex = "^Module:number list/data/(.+)$", process = "number list", },	{		regex = "^Module:accel/(.+)$", process = function(title, cats) local lang_code = title.subpageText local lang = lang_cache[lang_code] if lang then cats:insert(lang:getCanonicalName ..
