Something like getch(), textcolor() and gotoxy() in Ruby

I want to use these functions from the conio.c library (Borland) in Ruby, specially getch()开发者_C百科.

getch() gets a key from the keyboard without press enter.

textcolor() changes the color of the text in the terminal.

gotoxy() moves the cursor to other position of the terminal.

Someone knows the equivalents?

Thanks.

On ruby-forum I found a discussion about this, see Ncurses like library. There are both Ncurses and Curses. Not sure if there are other libs.
