Curses and Ruby

There are several curses implementations for Ruby.

1. curses

This is the implementation that PPCurses uses. It was originally part of the Ruby standard library and later got pushed out of the standard libary into a gem.

2. ncurses-ruby

The heir to ncurses gem. It is under active development.

3. ncurses

Created by Earle Clubb this gem has been frozen at version 0.9.1 since 2004. You probably don’t want this gem, you probably want ncurses-ruby.

rubygems.org/gems/ncurses

4. ffi-curses

A gem that makes curses available through FFI (foreign function interface), by Sean O’Halpin. The latest version is from 2011 (0.4.0).
