Use possessive version of variable in text

[jsladovi]

Is your feature request related to a problem? Please describe.
I'm trying to use the possessive version of a character's name in a text box and not sure how to achieve that best.

Describe the solution you'd like
Let's say our character_name variable can be two values, John and Chris. I want to use the variable in the following sentance: "This is {character_name}'s car." If I use John as the character name, everything will be fine, but for Chris it should be "This is Chris' car.", without the s after the apostrophe. Ideally, I would be able to write something along the lines of "This is {character_name:possessive} car." and it will fill it properly for both names.

Hi, better later then never.
There are multiple ways of doing this and I would choose depending on how often you need this. For example you could solve this with the conditional modifier:

This is {character_name}[if {{character_name}.ends_with("s")} ' / s] friend.

You could also use a method on an autoload:

This is {Helper.possesify({character_name})} friend.

Along a method in the Helper autoload like this:

func posessify(name:String) -> void:
     return name + "'" if name.ends_with("s") else name+"s"

This gives a lot more control in cases where the logic needed is more complicated then a simple if, for example a pluralize method that takes into account special cases like sheep, teeth, etc. In this case all it does is make it a little more fool-proof and shorter to write.

Lastly you could put a method like the above into a text modifier, which could be useful if you type it very often. Modifiers are free to create whatever syntax they like, but require more effort to implement that syntax.

This is [whos {character_name}] friend.
This is {character_name}@s friend.
