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 [1]ftp://ftp.gnu.org/pub/gnu/ncurses. - It is also available at [2]ftp://dickey.his.com/ncurses. - - Release Notes - - This release is designed to be upward compatible from ncurses 5.0 and - 5.1; very few applications will require recompilation, depending on - the platform. These are the highlights from the change-log since - ncurses 5.1 release. - - Interface changes: - * change type of ospeed variable back to short to match its use in - legacy applications. It was altered after ncurses 4.2 to speed_t - to repair a type mismatch which was introduced after 1.9.4 in - 1995. The principal users of termcap continued to use short, which - is not the same size. - NOTE: A few applications will have to be recompiled (about 1% of - the programs in a typical Linux distribution, 10% of the programs - that use ncurses). These are easy to identify with nm or strings. - * remove a private function _nc_can_clear_with(), which was built - with the configure --enable-expanded option but not used. - * add several private functions (prefixed with "_nc_") for tracing - chtype values in the debug library, and for better access and - buffer limit checking. - - New features and improvements: - * rewrote tgoto() to make it better support existing termcap - applications which use hardcoded strings rather than obtain all of - their information from the termcap file. If the string does not - appear to be a terminfo string (i.e., does not refer to a "%p" - parameter, or terminfo-style padding), and termcap support is - configured, tgoto() will interpret it as termcap. Otherwise, as - before, it will use tparm(). - * to ensure that the tgoto() changes work properly, added checks to - tic which report capabilities that do not reference the expected - number of parameters. - * new configure script options: - + option --disable-root-environ adds runtime checks which tell - ncurses to disregard $TERMINFO and similar environment - variables if the current user is root, or running - setuid/setgid. - + option --disable-assumed-color allows you to use the pre-5.1 - convention of default colors used for color-pair 0 to be - configured (see assume_default_colors()). - + implement configure script options that transform installed - program names, e.g., --program-prefix, including the manpage - names and cross references. - + option --with-database allows you to specify a different - terminfo source-file to install. On OS/2 EMX, the default is - misc/emx.src, otherwise misc/terminfo.src - + option --with-default-terminfo-dir allows you to specify the - default terminfo database directory. - + option --with-libtool allows you to build with libtool. - NOTE: libtool uses a different notation for numbering shared - library versions from the existing ncurses configuration. - + option --with-manpage-tbl causes the manpages to be - preprocessed by tbl(1) prior to installation, - + option --without-curses-h causes the installation process to - install curses.h as ncurses.h and make appropriate changes to - headers and manpages. - * modified configure script options: - + change symbol used by the --install-prefix configure option - from INSTALL_PREFIX to DESTDIR (the latter has become common - usage although the name is misleading). - + modify ld -rpath options (e.g., Linux, and Solaris) to use an - absolute pathname for the build tree's lib directory, - avoiding confusion with directories relative to the current - one with the installed programs. - + modified misc/run_tic.in to use tic -o, to eliminate - dependency on $TERMINFO variable for installs. - * terminfo database: - + updated xterm terminfo entries to match XFree86 xterm patch - #146. - + added amiga-vnc, Matrix Orbital, and QNX qansi to - misc/terminfo.src. - + added os2 entry to misc/emx.src. - + add S0 and E0 extensions to screen's terminfo entry since - otherwise the FreeBSD port makes it pass termcap equivalents - to tgoto, which would be misinterpreted by older versions of - ncurses. - * improvements to program usability: - + modify programs to use curses_version() string to report the - version of ncurses with which they are compiled rather than - the NCURSES_VERSION string. The function returns the patch - level in addition to the major and minor version numbers. - + modify tput program so it can be renamed or invoked via a - link as 'reset' or 'init', producing the same effect as - tput reset or tput init. - + add error checking to infocmp's -v and -m options to ensure - that the option value is indeed a number. - * improved performance: - + replace a lookup table in lib_vidattr.c used to decode - no_color_video with a logic expression which is faster. - - Major bug fixes: - * correct manlinks.sed script introduced in ncurses 5.1 to avoid - using ERE "\+", which is not understood by standard versions of - sed. This happens to work with GNU sed, but is not portable, and - was the initial motivation for this release. - * remove "hpux10.*" case from CF_SHARED_OPTS configure script macro. - This differed from the "hpux*" case by using reversed symbolic - links, which made the 5.1 version not match the configuration of - 5.0 shared libraries. - * guard against corrupt terminfo data: - + modify tparm() to disallow arithmetic on strings, analyze the - varargs list to read strings as strings and numbers as - numbers. - + modify tparm()'s internal function spop() to treat a null - pointer as an empty string. - + modify parse_format() in lib_tparm.c to ignore precision if - it is longer than 10000. - + rewrote limit checks in lib_mvcur.c using new functions - _nc_safe_strcat(), etc. Made other related changes to check - lengths used for strcat() and strcpy(). - * corrections to screen optimization: - + added special case in lib_vidattr.c to reset underline and - standout for devices that have no sgr0 defined. - + change handling of non_dest_scroll_region in tty_update.c to - clear text after it is shifted in rather than before shifting - out. Also correct row computation. - + modify rs2 capability in xterm-r6 and similar entries where - cursor save/restore bracketed the sequence for resetting - video attributes. The cursor restore would undo that. - * UTF-8 support: - + when checking LC_ALL, LC_CTYPE, and LANG environment - variables for UTF-8 locale, ignore those which are set to an - empty value, as per SUSV2. - + encode 0xFFFD in UTF-8 with 3 bytes, not 2. - + modify _nc_utf8_outch() to avoid sign-extension when checking - for out-of-range value. - * other library fixes: - + added checks for an empty $HOME environment variable, to - avoid retrieving terminfo descriptions from ./.terminfo . - + change functions _nc_parse_entry() and postprocess_termcap() - to avoid using strtok(), because it is non-reentrant. - + initialize fds[] array to 0's in _nc_timed_wait(); apparently - poll() only sets the revents members of that array when there - is activity corresponding to the related file. - + add a check for null pointer in Make_Enum_Type(). - + fix a heap problem with the c++ binding. - + correct missing includes for <string.h> in several places, - including the C++ binding. This is not noted by gcc unless we - use the -fno-builtin option. - * several fixes for tic: - + add a check for empty buffers returned by fgets() in - comp_scan.c next_char() function, in case tic is run on a - non-text file (fixes a core dump). - + modify tic to verify that its inputs are really files, in - case someone tries to read a directory (or /dev/zero). - + correct an uninitialized parameter to open_tempfile() in - tic.c which made "tic -I" give an ambiguous error message - about tmpnam. - + correct logic in adjust_cancels(), which did not check both - alternatives when reclassifying an extended name between - boolean, number and string, causing an infinite loop in tic. - * using new checks in tic for parameter counts in capability - strings, found/fixed several errors both in the terminfo database - and in the include/Caps file. - + modified several terminfo capability strings, including the - definitions for setaf, setab, in include/Caps to indicate - that the entries are parameterized. This information is used - to tell which strings are translated when converting to - termcap. This fixes a problem where the generated termcap - would contain a spurious "%p1" for the terminfo "%p1%d". - + correct parameter counts in include/Caps for dclk as well as - some printer-specific capabilities: csnm, defc, scs, scsd, - smgtp, smglp. - * various fixes for install scripts used to support configure - --srcdir and --with-install-prefix. - * correct several mismatches between manpage filename and ".TH" - directives, renaming dft_fgbg.3x to default_colors.3x and - menu_attribs.3x to menu_attributes.3x. - - Portability: - * configure script: - + newer config.guess, config.sub, including changes to support - OS/2 EMX. The configure script for OS/2 EMX still relies on a - patch since there is no (working) support for that platform - in the main autoconf distribution. - + make configure script checks on variables $GCC and $GXX - consistently compare against 'yes' rather than test if they - are nonnull, since either may be set to the corresponding - name of the C or C++ compiler. - + change configure script to use AC_CANONICAL_SYSTEM rather - than AC_CANONICAL_HOST, which means that configure --target - will set a default program-prefix. - + modify the check for big-core to force a couple of memory - accesses, which may work as needed for older/less-capable - machines (if not, there's still the explicit configure - option). - + modify configure test for tcgetattr() to allow for old - implementations, e.g., on BeOS, which only defined it as a - macro. - + add configure check for filesystems (such as OS/2 EMX) which - do not distinguish between upper/lowercase filenames, use - this to fix tags rules in makefiles. - + add MKncurses_def.sh to generate fallback definitions for - ncurses_cfg.h, to quiet gcc -Wundef warnings, modified - ifdef's in code to consistently use "#if" rather than - "#ifdef". - + change most remaining unquoted parameters of test in - configure script to use quotes, for instance fixing a problem - in the --disable-database option. - + modify scripts so that "make install.data" works on OS/2 EMX. - + modify scripts and makefiles so the Ada95 directory builds on - OS/2 EMX. - * library: - + replaced case-statement in _nc_tracebits() for CSIZE with a - table to simplify working around implementations that define - random combinations of the related macros to zero. - + improved OS/2 mouse support by retrying as a 2-button mouse - if code fails to set up a 3-button mouse. - + added private entrypoint _nc_basename(), used to consolidate - related code in progs, as well as accommodating OS/2 EMX - pathnames. - + alter definition of NCURSES_CONST to make it non-empty. - + redefine 'TEXT' in menu.h for AMIGA, since it is reported to - have an (unspecified) symbol conflict. - * programs: - + modified progs/tset.c and tack/sysdep.c to build with sgttyb - interface if neither termio or termios is available. Tested - this with FreeBSD 2.1.5 (which does have termios - but the - sgttyb does work). - - Features of Ncurses - - The ncurses package is fully compatible with SVr4 (System V Release 4) - curses: - * All 257 of the SVr4 calls have been implemented (and are - documented). - * Full support for SVr4 curses features including keyboard mapping, - color, forms-drawing with ACS characters, and automatic - recognition of keypad and function keys. - * An emulation of the SVr4 panels library, supporting a stack of - windows with backing store, is included. - * An emulation of the SVr4 menus library, supporting a uniform but - flexible interface for menu programming, is included. - * An emulation of the SVr4 form library, supporting data collection - through on-screen forms, is included. - * Binary terminfo entries generated by the ncurses tic(1) - implementation are bit-for-bit-compatible with the entry format - SVr4 curses uses. - * The utilities have options to allow you to filter terminfo entries - for use with less capable curses/terminfo versions such as the - HP/UX and AIX ports. - - The ncurses package also has many useful extensions over SVr4: - * 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). - * Unlike SVr3 curses, ncurses can write to the rightmost-bottommost - corner of the screen if your terminal has an insert-character - capability. - * Ada95 and C++ bindings. - * Support for mouse event reporting with X Window xterm and OS/2 - console windows. - * Extended mouse support via Alessandro Rubini's gpm package. - * The function wresize() allows you to resize windows, preserving - their data. - * The function use_default_colors() allows you to use the terminal's - default colors for the default color pair, achieving the effect of - transparent colors. - * The functions keyok() and define_key() 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. - * Support for 16-color terminals, such as aixterm and XFree86 xterm. - * Better cursor-movement optimization. The package now features a - cursor-local-movement computation more efficient than either BSD's - or System V's. - * 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. - * 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. - * 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). - * The tic(1)/captoinfo utility provided with ncurses has the ability - to translate many termcaps from the XENIX, IBM and AT&T extension - sets. - * A BSD-like tset(1) utility is provided. - * 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. - * 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.) - * 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. - * A script (capconvert) 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. - * 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. - * The table-of-entries utility toe makes it easy for users to see - exactly what terminal types are available on the system. - * 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 - #undef. - * An HTML "Introduction to Programming with NCURSES" document - provides a narrative introduction to the curses programming - interface. - - 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 - [3]http://www.vexus.ca/CDK.html - [4]http://dickey.his.com/cdk. - - ded - directory-editor - [5]http://dickey.his.com/ded. - - dialog - the underlying application used in Slackware's setup, and the - basis for similar applications on GNU/Linux. - [6]http://dickey.his.com/dialog. - - lynx - the character-screen WWW browser - [7]http://lynx.isc.org/release. - - Midnight Commander 4.1 - file manager - [8]www.gnome.org/mc/. - - mutt - mail utility - [9]http://www.mutt.org. - - ncftp - file-transfer utility - [10]http://www.ncftp.com. - - nvi - New vi versions 1.50 are able to use ncurses versions 1.9.7 and - later. - [11]http://www.bostic.com/vi/. - - tin - newsreader, supporting color, MIME - [12]http://www.tin.org. - - taper - tape archive utility - [13]http://members.iinet.net.au/~yusuf/taper/. - - vh-1.6 - Volks-Hypertext browser for the Jargon File - [14]http://www.bg.debian.org/Packages/unstable/text/vh.html. - - as well as some that use ncurses for the terminfo support alone: - - minicom - terminal emulator - [15]http://www.pp.clinet.fi/~walker/minicom.html. - - vile - vi-like-emacs - [16]http://dickey.his.com/vile. - - The ncurses distribution includes a selection of test programs - (including a few games). - -Who's Who and What's What - - The original developers of ncurses are [17]Zeyd Ben-Halim and [18]Eric - S.
