Module:TNT
Revision as of 11:15, 27 November 2019 by MediaWiki>Bawolff (Give a more useful error message if jsonconfig is missing. There have been three questions about this on the support desk from third party folks copying this template.)
Documentation for this module may be created at Module:TNT/doc
-- -- INTRO: (!!! DO NOT RENAME THIS PAGE !!!) -- This module allows any template or module to be copy/pasted between -- wikis without any translation changes. All translation text is stored -- in the global Data:*.tab pages on Commons, and used everywhere. -- -- SEE: https://www.mediawiki.org/wiki/Multilingual_Templates_and_Modules -- -- ATTENTION: -- Please do NOT rename this module - it has to be identical on all wikis. -- This code is maintained at https://www.mediawiki.org/wiki/Module:TNT -- Please do not modify it anywhere else, as it may get copied and override your changes. -- Suggestions can be made at https://www.mediawiki.org/wiki/Module_talk:TNT -- -- DESCRIPTION: -- The "msg" function uses a Commons dataset to translate a message -- with a given key (e.g. source-table), plus optional arguments -- to the wiki markup in the current content language. -- Use lang=xx to set language. Example: -- -- {{#invoke:TNT | msg -- | I18n/Template:Graphs.tab <!-- https://commons.wikimedia.org/wiki/Data:I18n/Template:Graphs.tab --> -- | source-table <!-- uses a translation message with id = "source-table" --> -- | param1 }} <!-- optional parameter --> -- -- -- The "doc" function will generate the <templatedata> parameter documentation for templates. -- This way all template parameters can be stored and localized in a single Commons dataset. -- NOTE: "doc" assumes that all documentation is located in Data:Templatedata/* on Commons. -- -- {{#invoke:TNT | doc | Graph:Lines }} -- uses https://commons.wikimedia.org/wiki/Data:Templatedata/Graph:Lines.tab -- if the current page is Template:Graph:Lines/doc -- local p = {} local i18nDataset = 'I18n/Module:TNT.tab' -- Forward declaration of the local functions local sanitizeDataset, loadData, link, formatMessage function p.msg(frame) local dataset, id local params = {} local lang = nil for k, v in pairs(frame.args) do if k == 1 then dataset = mw.text.trim(v) elseif k == 2 then id = mw.text.trim(v) elseif type(k) == 'number' then table.insert(params, mw.text.trim(v)) elseif k == 'lang' and v ~= '_' then lang = mw.text.trim(v) end end return formatMessage(dataset, id, params, lang) end -- Identical to p.msg() above, but used from other lua modules -- Parameters: name of dataset, message key, optional arguments -- Example with 2 params: format('I18n/Module:TNT', 'error_bad_msgkey', 'my-key', 'my-dataset') function p.format(dataset, key, ...) local checkType = require('libraryUtil').checkType checkType('format', 1, dataset, 'string') checkType('format', 2, key, 'string') return formatMessage(dataset, key, {...}) end -- Identical to p.msg() above, but used from other lua modules with the language param -- Parameters: language code, name of dataset, message key, optional arguments -- Example with 2 params: formatInLanguage('es', I18n/Module:TNT', 'error_bad_msgkey', 'my-key', 'my-dataset') function p.formatInLanguage(lang, dataset, key, ...) local checkType = require('libraryUtil').checkType checkType('formatInLanguage', 1, lang, 'string') checkType('formatInLanguage', 2, dataset, 'string') checkType('formatInLanguage', 3, key, 'string') return formatMessage(dataset, key, {...}, lang) end -- Obsolete function that adds a 'c:' prefix to the first param. -- "Sandbox/Sample.tab" -> 'c:Data:Sandbox/Sample.tab' function p.link(frame) return link(frame.args[1]) end function p.doc(frame) local dataset = 'Templatedata/' .. sanitizeDataset(frame.args[1]) return frame:extensionTag('templatedata', p.getTemplateData(dataset)) .. formatMessage(i18nDataset, 'edit_doc', {link(dataset)}) end function p.getTemplateData(dataset) -- TODO: add '_' parameter once lua starts reindexing properly for "all" languages local data = loadData(dataset) local names = {} for _, field in pairs(data.schema.fields) do table.insert(names, field.name) end local params = {} local paramOrder = {} for _, row in pairs(data.data) do local newVal = {} local name = nil for pos, val in pairs(row) do local columnName = names[pos] if columnName == 'name' then name = val else newVal[columnName] = val end end if name then params[name] = newVal table.insert(paramOrder, name) end end -- Work around json encoding treating {"1":{...}} as an [{...}] params['zzz123']='' local json = mw.text.jsonEncode({ params=params, paramOrder=paramOrder, description=data.description }) json = string.gsub(json,'"zzz123":"",?', "") return json end -- Local functions sanitizeDataset = function(dataset) if not dataset then return nil end dataset = mw.text.trim(dataset) if dataset == '' then return nil elseif string.sub(dataset,-4) ~= '.tab' then return dataset ..
