Announcing ncurses 5.0

The ncurses (new curses) library is a free software emulation of curses in System V Release 4.0, and more. It uses terminfo format, supports pads and color and multiple highlights and forms characters and function-key mapping, and has all the other SYSV-curses enhancements over BSD curses.

In mid-June 1995, the maintainer of 4.4BSD curses declared that he considered 4.4BSD curses obsolete, and is encouraging the keepers of Unix releases such as BSD/OS, freeBSD and netBSD to switch over to ncurses.

The ncurses code was developed under GNU/Linux. It should port easily to any ANSI/POSIX-conforming UNIX. It has even been ported to OS/2 Warp!

The distribution includes the library and support utilities, including a terminfo compiler tic(1), a decompiler infocmp(1), clear(1), tput(1), tset(1), and a termcap conversion tool captoinfo(1). Full manual pages are provided for the library and tools.

The ncurses distribution is available via anonymous FTP at the GNU distribution site ftp://ftp.gnu.org/pub/gnu/ncurses. It is also available at ftp://ftp.clark.net/pub/dickey/ncurses.

Release Notes

We decided to release ncurses as a new whole number release (5.0) because it incorporates several interface changes, including some that would invalidate existing shared libraries. These are the highlights from the change-log since ncurses 4.2 release.

Features of Ncurses

The ncurses package is fully compatible with SVr4 (System V Release 4) curses:

The ncurses package also has many useful extensions over SVr4:

State of the Package

Numerous bugs present in earlier versions have been fixed; the library is far more reliable than it used to be. Bounds checking in many `dangerous' entry points has been improved. The code is now type-safe according to gcc -Wall. The library has been checked for malloc leaks and arena corruption by the Purify memory-allocation tester.

The ncurses code has been tested with a wide variety of applications including (versions starting with those noted):

cdk
Curses Development Kit Curses Development Kit ftp://ftp.clark.net/pub/dickey/cdk.
ded
directory-editor ftp://ftp.clark.net/pub/dickey/ded.
dialog
the underlying application used in Slackware's setup, and the basis for similar applications on GNU/Linux.
lynx
the character-screen WWW browser
Midnight Commander 4.1
file manager
mutt
mail utility
ncftp
file-transfer utility
nvi
New vi versions 1.50 are able to use ncurses versions 1.9.7 and later.
tin

as well as some that use ncurses for the terminfo support alone:

minicom
terminal emulator
vile
vi-like-emacs ftp://ftp.clark.net/pub/dickey/vile.

The ncurses distribution includes a selection of test programs (including a few games).
