Checking for non-existant localization

Ok, so I have an item that is procedurally generated. As such, I'm also procedurally generating the name for it.
Code: Select all
localised_name = {"", {"item-name.steam-loco-cartridge"}, ": ", {"item-name."..name}},
The problem here is that, apparently, not all the items I'm catching actually
have an entry under [item-name] in the localization files and instead are using their [entity-name] entries. This results in game my item description showing the Unknown name string in these cases.
How can I check for {"item-name."..name} being non-existent and thus switch to trying {"entity-name."..name} instead?

No one, eh? I mean, I already know neither of these work:
Code: Select all
localised_name = {"", {"item-name.steam-loco-cartridge"}, ": ", {"item-name."..name or "entity-name."..name}}
localised_name = {"", {"item-name.steam-loco-cartridge"}, ": ", {"item-name."..name} or {"entity-name."..name}}
And I'm assuming the localization doesn't even get evaluated until after the data stages. So, what can I do? Aside from manually inputting names into my own localization file, which means I need to know about them (mods).

A workaround is to prefer the entity name if it exists.
Code: Select all
if item.localised_name then
localised_name = {"", {"item-name.steam-loco-cartridge"}, ": ", localised_name}
elseif item.place_result then
localised_name = {"", {"item-name.steam-loco-cartridge"}, ": ", {"entity-name."..item.place_result}}
else
localised_name = {"", {"item-name.steam-loco-cartridge"}, ": ", {"item-name."..name}}
end

Hmm, ok. I have noticed some that have item names but not entity, but those most likely don't have place results. Thanks.

Old post, but it still shows up in the google search results and there's now a solution:
https://lua-api.factorio.com/latest/concepts.html#LocalisedString wrote:if the key is a question mark ("?"), then the first valid parameter will be used. A parameter can be invalid if its name doesn't match any string template. If no parameters are valid, the last one is returned. This is useful to implement a fallback for missing locale templates.
So you can use:
Code: Select all
localised_name = {"", {"item-name.steam-loco-cartridge"}, ": ", {"?",{"item-name."..name}, {"entity-name."..name}}}
