Is there an easy way to color/control console output?

[Andy]

Hello everyone, is there an easy way for me to color my console
output? What about updating just a particular x/y coordinate? I
don't have time to learn Tk right now for a graphical GUI but just
being able to control the color and locations of what I print out
would be so nice. I am on windows right now but I would like the code
to be cross platform if it as all possible. Anyone here have any
suggestions for something light weight?

Take a look at ncurses. I've never used the ruby extension for it,
but it's a fairly easy way to manipulate the console. There is color
support. Also, Coderay (http://coderay.rubychan.de/) is a gem that
colorizes text based on coding language.

Also look at highline (http://highline.rubyforge.org/). It has
themeable colorized output for command line interfaces.

If all you need is basic ANSI, ie. color:

$ gem install facets
$ irb

require 'facets/ansicode'
include Console::ANSICode

p red, "Hello", blue, "World" "\e[31mHello\e[34mWorld"

p red{ "Hello" } + blue{ "World" }

"\e[31mHello\e[0m\e[34mWorld\e[0m"

We have Florian Frank to thank for the original version of this lib.

New question: what's a good escape code to query the current background color?

I dislike colored output that fails to contrast with my console...

What about updating just a particular x/y coordinate?

Either curses or ncurses, right?
