To keep it simple, does anyone here know of, and where to get, a Java package, or even just a single class that provides ANSI tag support for transfer over a socket, obviously for the use of colour support in a Java coded MUD(or any telnetable server really)? I'm quite confident it is out there, as java MUDclients have been made that supports ANSI interpretation, and others have made MUDs in Java, and I would assume that at least a few of them have colour support. So my question is, where can i get my hands on it?

To keep it simple, no. But I don't use Java Though it sure would be pretty simple to create your own ANSI color parser. Especially since you don't need the full support (I presume).

The format for the colors is \033[#(;#)m (the parentheses being an optional number. So the easiest way is to check for the ESC character (ascii = 27, octal \033) and go parsing through to the m. There are numerous sites that list these codes here is one: Ansi Color Codes

Personally, as I was on a mud the other day that was bashing across full color wilderness maps, I was thinking that it would be great for someone to take advantage of the cursor positioning code in a MUD specific client.

Anyways,

Ah yes. I had previously dug up the code for the ANSI colouring and tried it out, in the format specified at the end of that page (Black = \e[0;30m and so forth) and just tacked it on to the front of the string, but it didnt recognize the escape char, which i attributed to the fact that java uses Unicode text instead of ASCII text.
However, after viewing the page you specified, and useing "\033" instead of "\e" as the initial escape char, it worked properly, and i now have colour .
Thanks for the tip.

I'm working on using ANSI color with Java too, but I'm not quite sure if I'm doing it right...would this, for example, be a correct string?

"\033[0;34m Bla bla blah..."

I was also wondering if anyone could tell me how to test this? (I'm planning on starting a MUD, but I, er, haven't yet so I don't yet have a server with which to test it.)

Thanks,

Here's a little piece of code I wrote in 2001, you're welcome to use it. You also might be able to include the .jar's from some other project in your classpath, and reuse their classes...

Ok, thank you, Milliway; I was wondering something else, too, though. What if you want to have parts of the string have different colors? Do you just insert a new tag whenever you want to change the color?

[milliway]

out.println(ANSI.CYAN + "This is cyan" + ANSI.RED + ", and this is red.");
