Модуль:languages/error

Тандалган чалуу конвенциясы

local m_languages = require("Module:languages")
local lang = m_languages.getByCode(frame.args[1], 1)

Бул жерде биз экинчи параметрдеги параметр аты менен getByCode чакырабыз.

Эски (эскирген) чакыруу конвенциясы

require("Module:languages/error")(lang, param, text)

Үлгү параметри аркылуу өткөн болжолдуу тил кодун карайт жана тил кодунун жарактуу формасына жараша пайдалуу ката кабарын кайтарат (эки же үч негизги латын тамгалары, дефис менен бөлүнгөн үч кичине негизги латын тамгаларынан турган эки же үч топ).

№1 аргументке параметрдин маанисин жана №2 аргументке параметрдин атын кошуңуз. Мисалы, шаблондун lua параметри тил коду болушу керек болсо, бул функцияны төмөнкүчө атаса болот:

local m_languages = require("Module:languages")
local lang = m_languages.getByCode(frame.args[1]) or require("Module:languages/error")(frame.args[1], 1)

If you would like the error message to say something other than "language code", place the phrase in argument #3.

--[=[
Throw an error for an invalid language code or script code.

`lang_code` (required) is the bad code and can be nil or a non-string.

`param` (required) is the name of the parameter in which the code was contained. It can be a string, a number (for a
	numeric param, in which case the param will show up in the error message as an ordinal such as "first" or "second"),
	or `true` if no parameter can be clearly identified. It can also be a function of one argument (an error message) or
	two arguments (an error message and a number of stack frames to ignore, same as in the error() function itself), in
	which case the function will be called with the same error message as if `true` were passed in. (This is useful e.g.
	when parsing inline modifiers, where the parameter name may not be available or may not be so clearly identifiable,
	but an error function is often available.)

`code_desc` (optional) is text describing what the code is; by default, "language code".

`template_text` (optional) is a string specifying the template that generated the error, or a function
	to generate this string. If given, it will be displayed in the error message.

`not_real_lang` (optional), if given, indicates that the code is not in the form of a language code
	(e.g. it's a script code). Normally, this function checks for things that could plausibly be a language code:
	two or three lowercase letters, two or three groups of three lowercase letters with hyphens between them.
	If such a pattern is found, a different error message is displayed (indicating an invalid code) than otherwise
	(indicating a missing code). If `not_real_lang` is given, this check is suppressed.
