when i enter something like
data.localised_name = { "__1__ ["..data.name.."]", {'item-name.' .. data.name}}
it results in Unknown key: "Copper plate [copper-plate]"
how do i get rid of this unknown key thing?

i wanted to make a mod where modders can see the internal names of everything

I was searching for info on manipulating other mods locale strings myself, and came across this gem of a thread. Apparently, there are many places the game can get the localised name of an item, and item-name.blah is not guaranteed to exist.

viewtopic.php?f=28&t=62107

In my case, I get what I need by reading the localised_string property of the source object prototype in data.raw, and using that as a variable in my own locale strings. I just remembered that this actually doesn't work. You can assign entity.localised_string, but it always reads as empty even if the mod you are referencing was loaded before. At this point I'm falling back on hard-coding whether to expect the mod's entity-description to be set or not.

As I understand it, temporarily move the locale folder outside the mod and restart the game. At that point all in lieu of readable item name and description, the internal name will be displayed.

What do you mean by "see" ?
Maybe, I'm misunderstanding, but :
For 0.16 we have Mod Developer Tools :
https://mods.factorio.com/mod/ModDeveloperTools


And in 0.17 there's the show-debug-info-in-tooltips debug option, that looks to be largely inspired by this mod...

Placeholders like __1__ go into string templates, which are in locale files e.g. locale/en/mod-name.cfg.
The first entry in the table of a LocalisedString is the key for the template in the locale file.
So you need something like this in a .cfg file in locale/en/:
And then set up the prototype during the data stage with something like the following: Note that figuring out the correct entry for __1__ is more complex for things like recipes, which usually infer their name from their products.
