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 encouraged 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 has been in use for - some time with OpenBSD as the system curses library, and on FreeBSD - and NetBSD as an external package. 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/gnu/ncurses/ . - It is also available at [2]ftp://invisible-island.net/ncurses/ . - - Release Notes - - This release is designed to be upward compatible from ncurses 5.0 - through 5.5; very few applications will require recompilation, - depending on the platform. These are the highlights from the - change-log since ncurses 5.5 release. - - Interface changes: - * generate linkable stubs for some macros: - getbegx, getbegy, getcurx, getcury, getmaxx, getmaxy, getparx, - getpary, getpary, - and (for libncursesw) - wgetbkgrnd - - New features and improvements: - * library - + support hashed databases for the terminal descriptions. This - uses the Berkeley database, has been tested for several - versions on different platforms. - + add use_legacy_coding() function to support lynx's - font-switching feature. - + add extension nofilter(), to cancel a prior filter() call. - + add/install a package config script, e.g., ncurses5-config or - ncursesw5-config, according to configuration options. - + provide ifdef for NCURSES_NOMACROS which suppresses most - macro definitions from curses.h, i.e., where a macro is - defined to override a function to improve performance. - + make ifdef's consistent in curses.h for the extended colors - so the header file can be used for the normal curses library. - The header file installed for extended colors is a variation - of the wide-character configuration. - + improve tgetstr() by making the return value point into the - user's buffer, if provided. - + add ifdef's allowing ncurses to be built with tparm() using - either varargs (the existing status), or using a - fixed-parameter list (to match X/Open). - + widen the test for xterm kmous a little to allow for other - strings than "\E[M", e.g., for xterm-sco functionality in - xterm. - + modify wgetnstr() to return KEY_RESIZE if a sigwinch occurs. - + move prototypes for wide-character trace functions from - curses.tail to curses.wide to avoid accidental reference to - those if _XOPEN_SOURCE_EXTENDED is defined without ensuring - that <wchar.h> is included. - + change the way shared libraries (other than libtool) are - installed. Rather than copying the build-tree's libraries, - link the shared objects into the install directory. This - makes the --with-rpath option work except with $(DESTDIR). - + several improvements for rendering in hpterm. These are only - available if the library is configured using - --enable-xmc-glitch. - + Add NCURSES_NO_HARD_TABS and NCURSES_NO_MAGIC_COOKIE - environment variables to allow runtime suppression of the - related hard-tabs and xmc-glitch features. - * programs: - + add new test programs: chgat.c, demo_altkeys.c, echochar.c, - foldkeys.c, movewindow.c, redraw.c, (noting that existing - test programs also were modified to test additional - features). - + modify tack to test extended capability function-key strings. - + modify toe to access termcap data, e.g., via cgetent() - functions, or as a text file if those are not available. - + improve infocmp/tic -f option formatting. - + add toe -a option, to show all databases. This uses new - private interfaces in the ncurses library for iterating - through the list of databases. - + modify MKfallback.sh to use tic -x when constructing fallback - tables to allow extended capabilities to be retrieved from a - fallback entry. - * terminal database - + add terminfo entries for xfce terminal (xfce) and multi gnome - terminal (mgt) - + add nsterm-16color entry - + updated mlterm terminfo entry - + add kon, kon2 and jfbterm terminfo entry - + remove invis capability from klone+sgr, mainly used by linux - entry, since it does not really do this - + add ka2, kb1, kb3, kc2 to vt220-keypad as an extension - + add shifted up/down arrow codes to xterm-new as kind/kri - strings - + add hpterm-color terminfo entry - + add 256color variants of terminfo entries for programs which - are reported to implement this feature - + correct order of use-clauses in rxvt-basic entry which made - codes for f1-f4 vt100-style rather than vt220-style. - - Major bug fixes: - * correct a typo in configure --with-bool option for the case where - --without-cxx is used. - * move assignment from environment variable ESCDELAY from initscr() - down to newterm() so the environment variable affects timeouts for - terminals opened with newterm() as well. - * modify werase to clear multicolumn characters that extend into a - derived window. - * modify wchgat() to mark updated cells as changed so a refresh will - repaint those cells. - * correct logic in wadd_wch() and wecho_wch(), which did not guard - against passing the multi-column attribute into a call on - waddch(), e.g., using data returned by win_wch() - * fix redrawing of windows other than stdscr using wredrawln() by - touching the corresponding rows in curscr. - * reduce memory leaks in repeated calls to tgetent() by remembering - the last TERMINAL* value allocated to hold the corresponding data - and freeing that if the tgetent() result buffer is the same as the - previous call. - * modify read_termtype() so the term_names data is always allocated - as part of the str_table, a better fix for a memory leak. - * fix wins_nwstr(), which did not handle single-column non-8bit - codes. - * modify wbkgrnd() to avoid clearing the A_CHARTEXT attribute bits - since those record the state of multicolumn characters. - * improve SIGWINCH handling by postponing its effect during - newterm(), etc., when allocating screens. - * remove 970913 feature for copying subwindows as they are moved in - mvwin(). - * add checks in waddchnstr() and wadd_wchnstr() to stop copying when - a null character is found. - * add some checks to ensure current position is within scrolling - region before scrolling on a new line. - * add a workaround to ACS mapping to allow applications such as - test/blue.c to use the "PC ROM" characters by masking them with - A_ALTCHARSET. This worked up til 5.5, but was lost in the revision - of legacy coding. - - Portability: - * configure script: - + new options: - - --with-hashed-db - Use Berkeley hashed database for storing terminfo - data rather than storing each compiled entry in a - separate binary file within a directory tree. - - --without-dlsym - Do not use dlsym() to load GPM dynamically. - - --with-valgrind - Simplify building for testing with valgrind. - - --enable-wgetch-events - Compile with experimental wgetch-events code. - - --enable-signed-char - Store booleans in "signed char" rather than "char". - - + improved options: - - --disable-largefile - make the option work both ways. - - --with-gpm - The option now accepts a parameter, i.e., the name - of the dynamic GPM library to load via dlopen() - - --disable-symlinks - The option now allows one to disable symlink() in - tic even when link() does not work. - - * other configure/build issues: - + remove special case for Darwin in CF_XOPEN_SOURCE configure - macro. - + add configure check to ensure that SIGWINCH is defined on - platforms such as OS X which exclude that when _XOPEN_SOURCE, - etc., are defined - + use ld's -search_paths_first option on Darwin to work around - odd search rules on that platform. - + improve ifdef's for _POSIX_VDISABLE in tset to work with Mac - OS X. - + modify configure script to ensure that if the C compiler is - used rather than the loader in making shared libraries, the - $(CFLAGS) variable is also used. - + use ${CC} rather than ${LD} in shared library rules for - IRIX64, Solaris to help ensure that initialization sections - are provided for extra linkage requirements, e.g., of C++ - applications. - + improve some shared-library configure scripting for Linux, - FreeBSD and NetBSD to make --with-shlib-version work. - + split up dependency of names.c and codes.c in - ncurses/Makefile to work with parallel make. - + modify MKlib_gen.sh to change preprocessor-expanded _Bool - back to bool. - + modify progs/Makefile.in to make tput init work properly with - cygwin, i.e., do not pass a .exe in the reference string used - in check_aliases. - * library: - + ignore wide-acs line-drawing characters that wcwidth() claims - are not one-column. This is a workaround for Solaris' broken - locale support. - + reduce name-pollution in term.h by removing #define's for - HAVE_xxx symbols. - + fix #ifdef in c++/internal.h for QNX 6.1 - * test programs: - + modify test/configure script to allow building test programs - with PDCurses/X11. - + modified test programs to allow some to work with NetBSD - curses. Several do not because NetBSD curses implements a - subset of X/Open curses, and also lacks much of SVr4 - additions. But it is enough for comparison. - + improved test/configure to build test/ncurses on HPUX 11 - using the vendor curses. - + change configure script to produce test/Makefile from data - file. - - 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, and most EXTENDED features). It includes 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 FreeBSD - 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 modern 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://invisible-island.net/cdk/ - [4]http://www.vexus.ca/products/CDK/ - - ded - directory-editor - [5]http://invisible-island.net/ded/ - - dialog - the underlying application used in Slackware's setup, and the - basis for similar applications on GNU/Linux. - [6]http://invisible-island.net/dialog/ - - lynx - the character-screen WWW browser - [7]http://lynx.isc.org/release/ - - Midnight Commander - file manager - [8]http://www.ibiblio.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/ - - pinfo - Lynx-like info browser. - [12]http://dione.ids.pl/~pborys/software/pinfo/ - - tin - newsreader, supporting color, MIME [13]http://www.tin.org/ - - vh-1.6 - Volks-Hypertext browser for the Jargon File - [14]http://www.debian.org/Packages/unstable/text/vh.html - - as well as some that use ncurses for the terminfo support alone: - - minicom - terminal emulator - [15]http://alioth.debian.org/projects/minicom/ - - vile - vi-like-emacs - [16]http://invisible-island.net/vile/ - - The ncurses distribution includes a selection of test programs - (including a few games). - -Who's Who and What's What - - Zeyd Ben-Halim started it from a previous package pcurses, written by - Pavel Curtis.
