Scribunto Testing Area[edit]

This is not an actual Lua module. It exists to provide a convenient pseudo-namespace for code testing, hopefully preventing the main Module: namespace from becoming littered with experiments, as Lua modules cannot exist as subpages in the User: namespace.

Please name your experimental modules in the following format to help keep things tidy:

Module:Sandbox/Your User Name/Module name

You can use Special:PrefixIndex/Module:Sandbox to list modules in this area.

-- Placeholder

local p = {}

function p.assembleMessage(frame)
     --[[ This function takes existing translations for a given page
        translated using the translate extension and puts them together to
        generate the wikicode ready to be delivered by [Global message delivery]

    -- Initialize the message's static content

    local message = '<pre>{{subst:#switch:{{subst:CONTENTLANG}}'

    --[[ Build the list of language codes for which there is a translation,
        and remove English if it was mistakenly added since we already include
        it as default.
        We can't automatically list all available translations of the issue, so
        we need to input them manually as part of the module's call.
    translations = {}
    for key, value in pairs( frame.args ) do
        if ( mw.language.isKnownLanguageTag( value ) and value ~= 'en' )
            translations[value] = value
    -- Add English as default
    translations['#default'] = 'en'

    -- Loop through the languages to assemble the available translations

    for switchKey, langCode in pairs( translations ) do

            error. Ignore the incorrect language code and give warning.
