Throw an error for an invalid language code or script code.


local function make_language(code, data, useRequire)
`lang_code` (required) is the bad code and can be nil or a non-string.
local function conditionalRequire(modulename)
 
if useRequire then
`param` (required) is the name of the parameter in which the code was contained. It can be a string, a number
return require(modulename)
(for a numeric param, in which case the param will show up in the error message as an ordinal such as
else
"first" or "second"), or `true` if no parameter can be clearly identified.
return mw.loadData(modulename)
 
end
`code_desc` (optional) is text describing what the code is; by default, "language code".
end
 
`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.
