Question How to reference localized string in another localized string?

I have a localized string entry named

game_title

that represents the name of the game. Now I have another localized string entry where I want to insert the

game_title

, without having to write code for it.

How can I do this?

Example:

Code (CSharp):

1. game_title = Super Mario
2. quit_game_message = Do you really want to quit '<game_title>'?

The localized string of the

quit_game_message

should return:

Code (CSharp):

1. Do you really want to quit 'Super Mario'?

I guess it's somehow possible with SmartFormat, but I didn't figure out how.

 

Is it possible to perform this kind of replacement without explicitly providing arguments? In other words, having the system automatically parse the placeholder to find and inject the second localized string.

For example, a string entry:
"Your {Stats.strength_name} is too low to move this" , would search the string table 'Stats' for the key 'strength_name'.

The resulting string would be:
"Your Strength is too low to move this"

I feel like writing a custom Source might be the way to do it, based on https://docs.unity3d.com/Packages/c....0/manual/Smart/Creating-a-Custom-Source.html
I'm still a relative coding newbie and I'm not exactly sure how to go about it, as my attempts have been unsuccessful. Maybe adding some kind of unique character (ex. {@Stats.strength_name}) to flag the placeholder as a Localized String ref.

This is a simple example; I know I could simply write out the word Strength, but the goal here is convenience when renaming terms/mechanics, as well as enforcing uniformity across game terms. I've worked on games in the past where translations came back with 3-4 different terms for the same concept in the same language, because multiple translators each had their own ideas

 

I see, good points. I hadn't considered the potential async issues.
I think ultimately the best solution for me is to set up a Global variables list with all my common terms linked to their table entries.

After toying around a bit, I was able to get the behaviour I'm looking for with a very crude custom Source. It doesn't do any async loading (all my string tables are pre-loaded for the moment, still early in the project) and there's probably many other things that I overlooked, so I'm not sure how much mileage I can get out of it.

I placed it at the end of the Sources list to reduce the amount of cases in which it's called. Is that assumption correct?

Code (CSharp):

1. public class NestedLocStringSource : ISource
2.     {
3.         public bool TryEvaluateSelector(ISelectorInfo selectorInfo)
4.         {
5.             var selectors = selectorInfo.Placeholder.Selectors;
6.  
7.             if (selectors.Count != 2)
8.                 return false;
9.  
10.             TableReference tableRef = selectors[0].RawText;
11.             TableEntryReference keyRef = selectors[1].RawText;
12.  
13.             // check if String Table exists
14.             StringTable stringTable = LocalizationSettings.StringDatabase.GetTable(tableRef);      
15.             if (stringTable == null)
16.             {
17.                 Debug.LogWarning($"No String Table found '{tableRef}'");
18.                 return false;
19.             }
20.  
21.             // check if Key exists
22.             StringTableEntry stringEntry = stringTable.GetEntryFromReference(keyRef);      
23.             if (stringEntry == null)
24.             {
25.                 Debug.LogWarning($"No Loc Key found '{keyRef}' in String Table {tableRef}");
26.                 return false;
27.             }
28.  
29.             LocalizedString locString = new LocalizedString(tableRef, keyRef);
30.  
31.             selectorInfo.Result = locString.GetLocalizedString();
32.  
33.             return true;
34.         }
35.     }
