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.
local function make_language(code, data, useRequire)
 
local function conditionalRequire(modulename)
`param` (required) is the name of the parameter in which the code was contained. It can be a string, a number
if useRequire then
(for a numeric param, in which case the param will show up in the error message as an ordinal such as
return require(modulename)
"first" or "second"), or `true` if no parameter can be clearly identified.
else
 
return mw.loadData(modulename)
`code_desc` (optional) is text describing what the code is; by default, "language code".
end
 
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.
-- Temporarily convert various formatting characters to PUA to prevent them from being disrupted by the substitution process.
 
local function doTempSubstitutions(text, subbedChars, keepCarets, noTrim)
`not_real_lang` (optional), if given, indicates that the code is not in the form of a language code
-- Clone so that we don't insert any extra patterns into the table in package.loaded.
(e.g. it's a script code). Normally, this function checks for things that could plausibly be a language code:
local patterns = require("Module:table").shallowcopy(require("Module:languages/data/patterns"))
two or three lowercase letters, two or three groups of three lowercase letters with hyphens between them.
if keepCarets then
If such a pattern is found, a different error message is displayed (indicating an invalid code) than otherwise
table.insert(patterns, "((\\+)%^)")
(indicating a missing code). If `not_real_lang` is given, this check is suppressed.
table.insert(patterns, "((%^))")
]=]
end
 
-- Ensure any whitespace at the beginning and end is temp substituted, to prevent it from being accidentally trimmed. We only want to trim any final spaces added during the substitution process (e.g. by a module), which means we only do this during the first round of temp substitutions.
