Solved Question: List Pages

The title is a bit weird, sorry, but I don't know how to sum it up in a title (but I tried because I had to).
I have a log of many things in separate yamls, and eventually, the list will be really long (it could get long). Due to this and Minecraft limiting how much you can see in chat, it won't work out if I have each string listed out.
So plugins like logblock, when you get a log and there's a lot of logs, it'll separate the logs into pages, maybe 10 lines per page. It would look something like:

Logs:
Pages 1 of ___
First line
Second line
Third line
etc...
Use /page # to navigate through pages.

How would I do something like this (also, how would I separate the string into separate lines)?
Thanks.

 

Have a look at this resource

Thanks!
How would I get this to work with a list, though? With this I can make a page of one string, so how would I put "many strings" on there?

So I got it to work... Sorta. Now my list shows up like this:

instead of List: Page (1 of 1)
- asdf
- asdf

How are you implementing it?

I'm straight coyping that method.

Code:java

public void paginate(CommandSender sender, SortedMap<Integer, String> map,
            int page, int pageLength) {
        sender.sendMessage(ChatColor.YELLOW + "List: Page (" + String.valueOf(page) + " of " + (((map.size() % pageLength) == 0) ? map.size() / pageLength : (map.size() / pageLength) + 1) + ")");
        int i = 0, k = 0;
        page--;
        for (final Entry<Integer, String> e : map.entrySet()) {
            k++;
            if ((((page * pageLength) + i + 1) == k) && (k != ((page * pageLength) + pageLength + 1))) {
                i++;
                sender.sendMessage(ChatColor.YELLOW + " - " + e.getValue());
            }
        }
    }

Then to actually use this, I'm doing this:

Code:java

                                    for(String s : ad){
                                        SortedMap<Integer, String> map = new TreeMap<Integer, String>();
                                        map.put(1, s);
                                        paginate(sender, map, 1, 10);
                                    }

 

You're making a whole new map for each value in the list, do something like this instead:

Code:

int i = 0; // counter
SortedMap<bleh> map = blah blah; // new TreeMap
for (String s :ad)
  map.put(i++, s); // add each one once
paginate(sender, map, 1, 10); // then paginate once, with everything in the list in one map

Still the same error. Also, how would I change pages then load the things that would only be for that page?

Code:

String[] lines = ...
int page = ...
int perLine = 10;
int fromLine = (page - 1) * perLine;
int toLine = (fromLine + perLine > lines.length - 1) ? pages.length : (fromLine + perLine);
for(int i = fromLine; i < toLine; i++) {
  System.out.println(line[i]);
}

I believe that is right.

Hmm.. Can you explain how this works?
Thanks for contributing by the way.

Fixed.
