Getting a list of enabled strings from YML

Assume I have a yml file like this

Code:

foobar:
  foo:
    enabled: true
  bar:
    enabled: false
  foo2:
    enabled: false
  bar2:
    enabled: true

How would I go about getting all the strings with enabled being true? (In this case, foo and bar2)

 

There are no strings here. At least in the sense of what yaml considers as a string type.

 

The wiki has everything you need in this case:

http://wiki.bukkit.org/Configuration_API_Reference#Default_Values

 

By strings, I mean the name of the keys under foobar.

Wouldn't getStringList("foobar") return a List<String> containing
foo
bar
foo2
bar2
?

Or if not, what is the correct way of doing that?

I think you misunderstood me, if not, forgive me, but
I need to check, for every key under foobar if the subkey "enabled" is true, and then put those keys into a list

 

No, that's not how you read a yaml, there's structure to it - which is explained in the documentation I already provided above.

 

I've read the documentation, and I still don't quite understand completely

From what I've got, are you suggesting this?

Code:java

 
plugin.getConfig().getConfigurationSection("foobar").getKeys(false);
 

 

No, I understood you. What you're doing here is checking for the boolean value (true/false)

Code:

foobar:
  foo:
    enabled: true
  bar:
    enabled: false
  foo2:
    enabled: false
  bar2:
    enabled: true

foobar.foo.enabled would be the boolean and it's value would return true as above.

You're not getting the string of anything, and my suggestion is to read over that documentation, as it tells you everything you need to know about reading and setting yaml files.

http://wiki.bukkit.org/Configuration_API_Reference#Getting_Values

 

Yes that is how you read all the keys for foobar. You then need to use those keys to check if they are enabled.

 

yes, you'll also want to look at plugin.getConfig().getBoolean(); You're on the right track now.

I can't test the code yet at the moment myself, but would this theoretically work?

Code:java

 
Set<String> foo = plugin.getConfig().getConfigurationSection("foobar").getKeys(false);
List<String> bar = new ArrayList<String>(foo); //Because I like working with Lists better
for (String s : foo){
if(!plugin.getConfig().getBoolean("foobar."+foo+".enabled")){
if (validItems.contains(foo)){
validItems.remove(foo);
}
 

 

No, try this:

PHP:

List<String> keylist = plugin.getConfig().getConfigurationSection("foobar").getKeys(false);
for (String key in keylist)
{
if (getConfig().getBoolean(key))
{
//do stuff because this item is true.
}
}


I don't have a way of checking this right now either, but should be similar to that.

 

getKeys returns Set<String>, not sure if it'll cast correctly

Also, wouldn't getBoolean(key) get, for example, "foo" as a boolean, and not "foobar.foo.enabled"?

 

yes, that code is probably not working. but thats the structure you need. If you're still needing help when I'm home I'll get some working code for ya.

 

No you can't cast a set to a list, but you can iterate through it with a for loop none the less.

As for the key, you will either need the correct section or you will need to concatenate the right key.

 

Thanks guys, I'll test it out when I can.

For purely selfish reasons, I like working with Lists more, therefore,
List<String> bar = new ArrayList<String>(foo);

 

You may want to break that habbit once you start getting into bigger plug-ins, List can result in a performance loss over other options in many scenarios.
