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.<P> - -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.<P> - -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!<P> - -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.<P> - -The ncurses distribution is available via anonymous FTP at -the GNU distribution site -<A HREF="ftp://ftp.gnu.org/pub/gnu/ncurses">ftp://ftp.gnu.org/pub/gnu/ncurses</A>. -It is also available at -<A HREF="ftp://ftp.clark.net/pub/dickey/ncurses">ftp://ftp.clark.net/pub/dickey/ncurses</A>. - -<H1>Release Notes</H1> - -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. -<p> -Interface changes: -<ul> - <li>The principal source of changes to the interface comes from the - release of X/Open Curses in 1997. Earlier versions of ncurses (4.0 - and before) were based on a draft version of the specification. The - release version adds parameters to some functions to support the - evolving internationalization of curses. These summarize the impact: -<ul> - <li>modified several prototypes to correspond with 1997 version of - X/Open Curses (affects ABI since developers have used attr_get). - - <li>corrected prototypes for slk_* functions, using chtype rather than - attr_t. - - <li>the slk_attr_{set,off,on} functions need an additional void* - parameter according to XSI. - - <li>correct macros for wattr_set, wattr_get, separate wattrset macro from - these to preserve behavior that allows attributes to be combined with - color pair numbers. - - <li>reviewed/updated curses.h, term.h against X/Open Curses Issue 4 - Version 2. This includes making some parameters NCURSES_CONST - rather than const, e.g., in termcap.h. - - <li>reviewed/corrected macros in curses.h as per XSI document. - - <li>add set_a_attributes and set_pglen_inch to terminfo structure, as per - XSI and Solaris 2.5. -</ul> - <li>The newest version of the X/Open Curses is implemented on Solaris - and other vendor's systems. It adds new features to the terminfo - descriptions: -<ul> - <li>implement tparm %l format. - - <li>implement tparm printf-style width and precision for %s, %d, %x, %o - as per XSI. -</ul> - <li>We made additional changes to reduce impact by future interface - changes: -<ul> - <li>rename key_names[] array to _nc_key_names since it is not part of - the curses interface. - - <li>move macro winch to a function, to hide details of struct ldat -</ul> - <li>modify configure script to embed ABI in shared libraries for HP-UX - 10.x (detailed request by Tim Mooney). - - <li>modify configuration of shared libraries on Digital Unix so that - versioning is embedded in the library, rather than implied by - links (patch by Tim Mooney). -</ul> -New features: -<ul> - <li>enable sigwinch handler by default. - - <li>turn on hashmap scrolling code by default - - <li>improved support for termcap applications -<ul> - <li>modify tput to accept termcap names as an alternative to terminfo - names. - - <li>provide support for termcap PC variable by copying it from terminfo - data and using it as the padding character in tputs. - - <li>provide support for termcap ospeed variable by copying it from the - internal cur_term member, and using ospeed as the baudrate - reference for the delay_output and tputs functions. - - <li>change name-comparisons in lib_termcap to compare no more than 2 - characters. - - <li>add configure option --enable-tcap-names, which essentially - allows users to define new capabilities as in termcap. -</ul> - <li>add mouse support to ncurses menus. - - <li>add mouse and dll support for OS/2 EMX - - <li>modify terminfo parsing to accept octal and hexadecimal constants - - <li>add configure option --enable-no-padding, to allow environment - variable $NCURSES_NO_PADDING to eliminate non-mandatory padding, - thereby making terminal emulators (e.g., for vt100) a little more - efficient. - - <li>modify lib_color.c to eliminate dependency on orig_colors and - orig_pair, since SVr4 curses does not require these either, but - uses them when they are available. - - <li>add -f option to infocmp and tic, which formats the terminfo - if/then/else/endif so that they are readable (with newlines and - tabs). - - <li>modify tic to compile into %'char' form in preference to %{number}, - since that is a little more efficient. -</ul> -Major bug fixes: -<ul> - <li>modify lib_tstp.c to block SIGTTOU when handling SIGTSTP, fixes a - problem where ncurses applications which were run via a shell script - would hang when given a ^Z. Also, check if the terminal's process - group is consistent, i.e., a shell has not taken ownership of it, - before deciding to save the current terminal settings in the SIGTSTP - handler. - - <li>suppress sc/rc capabilities from terminal description if they appear - in smcup/rmcup. This affects only scrolling optimization, to fix a - problem reported by several people with xterm's alternate screen, - though the problem is more general. - - <li>modify relative_move and tputs to avoid an interaction with the - BSD-style padding. The relative_move function could produce a string - to replace on the screen which began with a numeric character, which - was then interpreted by tputs as padding. - - <li>modify setupterm so that cancelled strings are treated the same as - absent strings, cancelled and absent booleans false (does not affect - tic, infocmp). - - <li>modify lib_vidattr.c to allow for terminal types (e.g., xterm-color) - which may reset all attributes in the 'op' capability, so that colors - are set before turning on bold and other attributes, but still after - turning attributes off. - - <li>use 'access()' to check if ncurses library should be permitted to - open or modify files with fopen/open/link/unlink/remove calls, in - case the calling application is running in setuid mode. - - <li>correction to doupdate, for case where terminal does not support - insert/delete character. The logic did not check that there was a - difference in alignment of changes to old/new screens before - repainting the whole non-blank portion of the line. Modified to fall - through into logic that reduces by the portion which does not differ. -</ul> - -<H1>Features of Ncurses</H1> - -The ncurses package is fully compatible with SVr4 (System V Release 4) curses: - -<UL> -<LI>All 257 of the SVr4 calls have been implemented (and are documented). -<LI>Full support for SVr4 curses features including keyboard mapping, color, -forms-drawing with ACS characters, and automatic recognition of keypad -and function keys. -<LI>An emulation of the SVr4 panels library, supporting -a stack of windows with backing store, is included. -<LI>An emulation of the SVr4 menus library, supporting -a uniform but flexible interface for menu programming, is included. -<LI>An emulation of the SVr4 form library, supporting -data collection through on-screen forms, is included. -<LI>Binary terminfo entries generated by the ncurses tic(1) implementation -are bit-for-bit-compatible with the entry format SVr4 curses uses. -<LI>The utilities have options to allow you to filter terminfo -entries for use with less capable <STRONG>curses</STRONG>/<STRONG>terminfo</STRONG> -versions such as the HP/UX and AIX ports.</UL> - -The ncurses package also has many useful extensions over SVr4: - -<UL> -<LI>The API is 8-bit clean and base-level conformant with the X/OPEN curses -specification, XSI curses (that is, it implements all BASE level features, -but not all EXTENDED features). Most EXTENDED-level features not directly -concerned with wide-character support are implemented, including many -function calls not supported under SVr4 curses (but portability of all -calls is documented so you can use the SVr4 subset only). -<LI>Unlike SVr3 curses, ncurses can write to the rightmost-bottommost corner -of the screen if your terminal has an insert-character capability. -<LI>Ada95 and C++ bindings. -<LI>Support for mouse event reporting with X Window xterm and OS/2 console windows. -<LI>Extended mouse support via Alessandro Rubini's gpm package. -<LI>The function <CODE>wresize()</CODE> allows you to resize windows, preserving -their data. -<LI>The function <CODE>use_default_colors()</CODE> allows you to -use the terminal's default colors for the default color pair, -achieving the effect of transparent colors. -<LI>The functions <CODE>keyok()</CODE> -and <CODE>define_key()</CODE> allow -you to better control the use of function keys, -e.g., disabling the ncurses KEY_MOUSE, -or by defining more than one control sequence to map to a given key code. -<LI>Support for 16-color terminals, such as aixterm and XFree86 xterm. -<LI>Better cursor-movement optimization. The package now features a -cursor-local-movement computation more efficient than either BSD's -or System V's. -<LI>Super hardware scrolling support. The screen-update code incorporates -a novel, simple, and cheap algorithm that enables it to make optimal -use of hardware scrolling, line-insertion, and line-deletion -for screen-line movements. This algorithm is more powerful than -the 4.4BSD curses quickch() routine. -<LI>Real support for terminals with the magic-cookie glitch. The -screen-update code will refrain from drawing a highlight if the magic- -cookie unattributed spaces required just before the beginning and -after the end would step on a non-space character. It will -automatically shift highlight boundaries when doing so would make it -possible to draw the highlight without changing the visual appearance -of the screen. -<LI>It is possible to generate the library with a list of pre-loaded -fallback entries linked to it so that it can serve those terminal types even -when no terminfo tree or termcap file is accessible (this may be useful -for support of screen-oriented programs that must run in single-user mode). -<LI>The tic(1)/captoinfo utility provided with ncurses has the -ability to translate many termcaps from the XENIX, IBM and -AT&T extension sets. -<LI>A BSD-like tset(1) utility is provided. -<LI>The ncurses library and utilities will automatically read terminfo -entries from $HOME/.terminfo if it exists, and compile to that directory -if it exists and the user has no write access to the system directory. -This feature makes it easier for users to have personal terminfo entries -without giving up access to the system terminfo directory. -<LI>You may specify a path of directories to search for compiled -descriptions with the environment variable TERMINFO_DIRS (this -generalizes the feature provided by TERMINFO under stock System V.) -<LI>In terminfo source files, use capabilities may refer not just to -other entries in the same source file (as in System V) but also to -compiled entries in either the system terminfo directory or the user's -$HOME/.terminfo directory. -<LI>A script (<STRONG>capconvert</STRONG>) is provided to help BSD users -transition from termcap to terminfo. It gathers the information in a -TERMCAP environment variable and/or a ~/.termcap local entries file -and converts it to an equivalent local terminfo tree under $HOME/.terminfo. -<LI>Automatic fallback to the /etc/termcap file can be compiled in -when it is not possible to build a terminfo tree. This feature is neither -fast nor cheap, you don't want to use it unless you have to, -but it's there. -<LI>The table-of-entries utility <STRONG>toe</STRONG> makes it easy for users to -see exactly what terminal types are available on the system. -<LI>The library meets the XSI requirement that every macro entry -point have a corresponding function which may be linked (and will be -prototype-checked) if the macro definition is disabled with -<CODE>#undef</CODE>. -<LI>An HTML "Introduction to Programming with NCURSES" document provides -a narrative introduction to the curses programming interface. -</UL> - -<H1>State of the Package</H1> - -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.<P> - -The ncurses code has been tested with a wide variety of applications -including (versions starting with those noted): -<DL> -<DT> cdk -<DD> Curses Development Kit -<A HREF="http://www.vexus.ca/CDK.html">Curses Development Kit</a> -<A HREF="ftp://ftp.clark.net/pub/dickey/cdk">ftp://ftp.clark.net/pub/dickey/cdk</A>. -<DT> ded -<DD> directory-editor -<A HREF="ftp://ftp.clark.net/pub/dickey/ded">ftp://ftp.clark.net/pub/dickey/ded</A>. -<DT> dialog -<DD> the underlying application used in Slackware's setup, and the basis -for similar applications on GNU/Linux. -<DT> lynx -<DD> the character-screen WWW browser -<DT> Midnight Commander 4.1 -<DD> file manager -<DT> mutt -<DD> mail utility -<DT> ncftp -<DD> file-transfer utility -<DT> nvi -<DD> New vi versions 1.50 are able to use ncurses versions 1.9.7 and later. -<DT> tin -<DD> newsreader, supporting color, MIME -<A HREF="ftp://ftp.akk.uni-karlsruhe.de/pub/news/clients/tin-unoff">ftp://ftp.akk.uni-karlsruhe.de/pub/news/clients/tin-unoff</A>. -<DT> taper -<DD> tape archive utility -<DT> vh-1.6 -<DD> Volks-Hypertext browser for the Jargon File -</DL> -as well as some that use ncurses for the terminfo support alone: -<DL> -<DT> minicom -<DD> terminal emulator -<DT> vile -<DD> vi-like-emacs -<A HREF="ftp://ftp.clark.net/pub/dickey/vile">ftp://ftp.clark.net/pub/dickey/vile</A>. -</DL> -<P> - -The ncurses distribution includes a selection of test programs (including -a few games). - -<H2>Who's Who and What's What</H2> - -The original developers of ncurses are <A -HREF="mailto:zmbenhal@netcom.com">Zeyd Ben-Halim</A> and -<A HREF="http://www.ccil.org/~esr/home.html">Eric S.
