Solved Remove from StringList in config

Hey! Today, I was working on a plugin which saves strings to a stringlist in a config. BUT, after I save them, I want to somehow delete them but I don't know how. So, I don't want to clear stringlist, just remove a string line from a stringlist Hope you understand and reply soon

 

@Roborack17
Get the string list from config, remove the entry, and save it to config again.

 

Do you have any example for it? I actually want to remove string line by command like /remove 1 and it'll remove the first string I guess, so is it possible?

 

@Roborack17
Indeed, all you need to do is get the list from config like usual and save it to a variable. Then just use the "remove()" method, and then save the variable back to config.

 

@AlvinB
Well, how do save it to a variable? That's the problem I guess

 

@Roborack17
You can learn how to save things to configs at the following link:
http://wiki.bukkit.org/Configuration_API_Reference

 

I didn't find there what I was looking for. I looked to get the string line by typing the number of it and to remove it. Do you know to do that?

 

@Roborack17
I think it's time for some Java tutorials. Knowing what a variable is is an essential part of programming.

 

I know what variable is, but I don't know how to turn string list to a varible

 

@Roborack17
Well, if you know how to get the list from config and know what a variable is, then you should be able to pull it off.

 

But how do I get a string line?

 

@Roborack17
To add onto what @AlvinB said, a variable is an object that can be referenced. To load a string out of a config, create a String variable and set it equal to the string from the config. If you don't know how to get an object from a config, please review the link.

 

I do know how do get a string from a config, but not how to get a string from a string list. I think you didn't understand me very well

 

@Roborack17

Code:java

getConfig().getStringList("path")

?

 

@AlvinB
Ok, I'm going to explain you a little bit more

So, my string list in a config is like this:

StringList:
- String 1
- String 2
- String 3

And I want to delete a string 2 by typing command like /string remove 2, but the String 2 is configurable and its content isn't always the same. There is command /string add string, and it adds the string to the string list. Hope you get it.

Finally Thanks, I'll try it now

Do you mean List#get(index) and List#remove(index)?

[edit] Yes, you are looking for this. Load the list, remove the object at that index (using List#remove(index). In your example, remove the object at index 1), and reset the list in the config.

 

Thanks man! It worked
