 I would like to share with my new library written in D. As name 
 may suggest (or not) it adds color to your console output, it 
 works on both Linux and Windows platforms. I haven't seen any 
 similar library for D language, so I decided to create this one.

Ah, this can be used to pimp the console output. Give it the following additions to make it complete and useful: * fg/bg colors are just two attributes, add e.g. bold, underline, italic (http://en.wikipedia.org/wiki/ANSI_escape_code) * detect type of "stdout"; terminal or pipe/file (Posix: http://linux.die.net/man/3/isatty) The latter is important to not accidentally write escape codes into a file if output is redirected. Some tools let you chose to output with or without colors, so it would be nice if you library could offer a "isAnsiTerminal" function, so the programmer can chose to output with or without colors. :) This is a good idea! -- Marco

Okay, I think I will have to set up VM and start working on it. Thanks for your suggestion by the way!

Not yet. But I guess I will have to add it soon. Regards, Robik.
