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. It is also available + at [2]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. + + Interface changes: + * 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: + + modified several prototypes to correspond with 1997 version + of X/Open Curses (affects ABI since developers have used + attr_get). + + corrected prototypes for slk_* functions, using chtype rather + than attr_t. + + the slk_attr_{set,off,on} functions need an additional void* + parameter according to XSI. + + 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. + + 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. + + reviewed/corrected macros in curses.h as per XSI document. + + add set_a_attributes and set_pglen_inch to terminfo + structure, as per XSI and Solaris 2.5. + * 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: + + implement tparm %l format. + + implement tparm printf-style width and precision for %s, %d, + %x, %o as per XSI. + * We made additional changes to reduce impact by future interface + changes: + + change key_names[] array to static since it is not part of + the curses interface. + + move macro winch to a function, to hide details of struct + ldat + * modify configure script to embed ABI in shared libraries for HP-UX + 10.x (detailed request by Tim Mooney). + * 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). + + New features: + * enable sigwinch handler by default. + * turn on hashmap scrolling code by default + * improved support for termcap applications + + modify tput to accept termcap names as an alternative to + terminfo names. + + provide support for termcap PC variable by copying it from + terminfo data and using it as the padding character in tputs. + + 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. + + change name-comparisons in lib_termcap to compare no more + than 2 characters. + + add configure option --enable-tcap-names, which essentially + allows users to define new capabilities as in termcap. + * add mouse support to ncurses menus. + * add mouse and dll support for OS/2 EMX + * modify terminfo parsing to accept octal and hexadecimal constants + * 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. + * 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. + * add -f option to infocmp and tic, which formats the terminfo + if/then/else/endif so that they are readable (with newlines and + tabs). + * modify tic to compile into %'char' form in preference to + %{number}, since that is a little more efficient. + + Major bug fixes: + * 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. + * 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. + * 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. + * modify setupterm so that cancelled strings are treated the same as + absent strings, cancelled and absent booleans false (does not + affect tic, infocmp). + * 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. + * 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. + * 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. + + 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 SVr4 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): + + ded + directory-editor [3]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-2.7 + the character-screen WWW browser + + Midnight Commander 4.1 + file manager + + mutt 0.88 + mail utility + + ncftp 2.0 + file-transfer utility + + nvi + New vi versions 1.50 are able to use ncurses versions 1.9.7 and + later. + + taper + tape archive utility + + vh-1.6 + Volks-Hypertext browser for the Jargon File + + as well as some that use ncurses for the terminfo support alone: + + minicom-1.75 + terminal emulator + + tin-unoff + tin 1.4 newsreader, supporting color, MIME + [4]ftp://ftp.akk.uni-karlsruhe.de/pub/news/clients/tin-unoff. + + vile + vi-like-emacs [5]ftp://ftp.clark.net/pub/dickey/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 [6]Zeyd Ben-Halim and [7]Eric + S.

See the README file for a roadmap to the package. + +If you are a Linux or FreeBSD or NetBSD distribution integrator or packager, +please read and act on the section titled IF YOU ARE A SYSTEM INTEGRATOR +below. + +If you are converting from BSD curses and do not have root access, be sure +to read the BSD CONVERSION NOTES section below. + +If you are using a version of XFree86 xterm older than 3.1.2F, see the section +on RECENT XTERM VERSIONS below. + +If you are trying to build GNU Emacs using ncurses for terminal support, +read the USING NCURSES WITH EMACS section below. + +If you are trying to build applications using gpm with ncurses, +read the USING NCURSES WITH GPM section below. + +If you are trying to build Elvis using ncurses for terminal support, +read the USING NCURSES WITH ELVIS section below. + +If you are running over the Andrew File System see the note below on +USING NCURSES WITH AFS. + +If you want to build the Ada95 binding, go to the Ada95 directory and +follow the instructions there.

First, decide whether you want ncurses to replace your existing library (in + which case you'll need super-user privileges) or be installed in parallel + with it. + + The --prefix option to configure changes the root directory for installing + ncurses. The default is in subdirectories of /usr/local. Use + --prefix=/usr to replace your default curses distribution. This is the + default for Linux and BSD/OS users. + + The package gets installed beneath the --prefix directory as follows: + + In $(prefix)/bin: tic, infocmp, captoinfo, tset, + reset, clear, tput, toe + In $(prefix)/lib: libncurses*.* libcurses.a + In $(prefix)/share/terminfo: compiled terminal descriptions + In $(prefix)/include: C header files + Under $(prefix)/man: the manual pages + + Note however that the configure script attempts to locate previous + installation of ncurses, and will set the default prefix according to where + it finds the ncurses headers. + +2. Type `./configure' in the top-level directory of the distribution to + configure ncurses for your operating system and create the Makefiles. + Besides --prefix, various configuration options are available to customize + the installation; use `./configure --help' to list the available options. + + If your operating system is not supported, read the PORTABILITY section in + the file ncurses/README for information on how to create a configuration + file for your system. + + The `configure' script generates makefile rules for one or more object + models and their associated libraries: + + libncurses.a (normal) + + libcurses.a (normal, a link to libncurses.a) + This gets left out if you configure with --disable-overwrite. + + libncurses.so (shared) + + libncurses_g.a (debug) + + libncurses_p.a (profile) + + If you do not specify any models, the normal and debug libraries will be + configured. Typing `configure' with no arguments is equivalent to: + + ./configure --with-normal --with-debug --enable-overwrite + + Typing + + ./configure --with-shared + + makes the shared libraries the default, resulting in + + ./configure --with-shared --with-normal --with-debug --enable-overwrite + + If you want only shared libraries, type + + ./configure --with-shared --without-normal --without-debug + + Rules for generating shared libraries are highly dependent upon the choice + of host system and compiler. We've been testing shared libraries on Linux + and SunOS with gcc, but more work needs to be done to make shared libraries + work on other systems. + + You can make curses and terminfo fall back to an existing file of termcap + definitions by configuring with --enable-termcap. If you do this, the + library will search /etc/termcap before the terminfo database, and will + also interpret the contents of the TERM environment variable. See the + section BSD CONVERSION NOTES below. + +3. Type `make'. Ignore any warnings, no error messages should be produced. + This should compile the ncurses library, the terminfo compiler tic(1), + captoinfo(1), infocmp(1), toe(1), clear(1) tset(1), reset(1), and tput(1) + programs (see the man pages for explanation of what they do), some test + programs, and the panels, menus, and forms libraries. + +4. Run ncurses and several other test programs in the test directory to + verify that ncurses functions correctly before doing an install that + may overwrite system files. Read the file test/README for details on + the test programs. + + NOTE: You must have installed the terminfo database, or set the + environment variable $TERMINFO to point to a SVr4-compatible terminfo + database before running the test programs. Not all vendors' terminfo + databases are SVr4-compatible, but most seem to be. Exceptions include + DEC's Digital Unix (formerly known as OSF/1). + + The ncurses program is designed specifically to test the ncurses library. + You can use it to verify that the screen highlights work correctly, that + cursor addressing and window scrolling works OK, etc. + +5. Once you've tested, you can type `make install' to install libraries, + the programs, the terminfo database and the man pages. Alternately, you + can type `make install' in each directory you want to install. In the + top-level directory, you can do a partial install using these commands: + + 'make install.progs' installs tic, infocmp, etc... + 'make install.includes' installs the headers. + 'make install.libs' installs the libraries (and the headers). + 'make install.data' installs the terminfo data. (Note: `tic' must + be installed before the terminfo data can be + compiled). + 'make install.man' installs the man pages. + + ############################################################################ + # CAVEAT EMPTOR: `install.data' run as root will NUKE any existing # + # terminfo database. If you have any custom or unusual entries SAVE them # + # before you install ncurses. I have a file called terminfo.custom for # + # this purpose. Don't forget to run tic on the file once you're done. # + ############################################################################ + + The terminfo(5) manual page wants to be preprocessed with tbl(1) before + being formatted by nroff(1). Modern man(1) implementations tend to do + this by default, but you may want to look at your version's man page + to be sure. + + If the system already has a curses library that you need to keep using + for some bizarre binary-compatibility reason, you'll need to distinguish + between it and ncurses. If ncurses is installed outside the standard + directories (/usr/include and /usr/lib) then all your users will need + to use the -I option to compile programs and -L to link them. + + If you have BSD curses installed in your system and you accidentally + compile using its curses.h you'll end up with a large number of + undefined symbols at link time. _waddbytes is one of them. + + IF YOU DO NOT HAVE ROOT: Change directory to the `progs' subdirectory + and run the `capconvert' script. This script will deduce various things + about your environment and use them to build you a private terminfo tree, + so you can use ncurses applications. + + If more than one user at your site does this, the space for the duplicate + trees is wasted. Try to get your site administrators to install a system- + wide terminfo tree instead. + + See the BSD CONVERSION NOTES section below for a few more details. + +6. The c++ directory has C++ classes that are built on top of ncurses and + panels. You need to have c++ (and its libraries) installed before you can + compile and run the demo. + + If you do not have C++, you must use the --without-cxx option to tell + the configure script to not attempt to build the C++ bindings. + +7. If you're running an older Linux, you must either (a) tell Linux that the + console terminal type is `linux' or (b) make a link to or copy of the + linux entry in the appropriate place under your terminfo directory, named + `console'. All 1.3 and many 1.2 distributions (including Yggdrasil and + Red Hat) already have the console type set to `linux'. + + The way to change the wired-in console type depends on the configuration + of your system. This may involve editing /etc/inittab, /etc/ttytype, + /etc/profile and other such files. + + Warning: this is not for the fainthearted, if you mess up your console + getty entries you can make your system unusable! However, if you are + a distribution maker, this is the right thing to do (see the note for + integrators near the end of this file). + + The easier way is to link or copy l/linux to c/console under your terminfo + directory. Note: this will go away next time you do `make install.data' + and you'll have to redo it. There is no need to have entries for all + possible screen sizes, ncurses will figure out the size automatically. + +IF YOU ARE A SYSTEM INTEGRATOR: + + Beginning with 1.9.9, the ncurses distribution includes both a tset + utility and /usr/share/tabset directory. If you are installing ncurses, + it is no longer either necessary or desirable to install tset-jv. + + Configuration and Installation: + + Configure with --prefix=/usr to make the install productions put + libraries and headers in the correct locations (overwriting any + previous curses libraries and headers). This will put the terminfo + hierarchy under /usr/share/terminfo; you may want to override this with + --datadir=/usr/share/misc; terminfo and tabset are installed under the + data directory. + + Please configure the ncurses library in a pure-terminfo mode; that + is, with the --disable-termcap option. This will make the ncurses + library smaller and faster. The ncurses library includes a termcap + emulation that queries the terminfo database, so even applications + that use raw termcap to query terminal characteristics will win + (providing you recompile and relink them!). + + If you must configure with termcap fallback enabled, you may also + wish to use the --enable-getcap option. This option speeds up + termcap-based startups, at the expense of not allowing personal + termcap entries to reference the terminfo tree. See the code in + ncurses/tinfo/read_termcap.c for details. + + Note that if you have $TERMCAP set, ncurses will use that value + to locate termcap data. In particular, running from xterm will + set $TERMCAP to the contents of the xterm's termcap entry. + If ncurses sees that, it will not examine /etc/termcap. + + Keyboard Mapping: + + The terminfo file assumes that Shift-Tab generates \E[Z (the ECMA-48 + reverse-tabulation sequence) rather than ^I. Here are the loadkeys -d + mappings that will set this up: + + keycode 15 = Tab Tab + alt keycode 15 = Meta_Tab + shift keycode 15 = F26 + string F26 ="\033[Z" + + Naming the Console Terminal + + In various Linuxes (and possibly elsewhere) there has been a practice + of designating the system console driver type as `console'. Please + do not do this any more! It complicates peoples' lives, because it + can mean that several different terminfo entries from different + operating systems all logically want to be called `console'. + + Please pick a name unique to your console driver and set that up + in the /etc/inittab table or local equivalent. Send the entry to the + terminfo maintainer (listed in the misc/terminfo file) to be included + in the terminfo file, if it's not already there. See the + term(7) manual page included with this distribution for more on + conventions for choosing type names. + + Here are some recommended primary console names: + + linux -- Linux console driver + freebsd -- FreeBSD + netbsd -- NetBSD + bsdos -- BSD/OS + + If you are responsible for integrating ncurses for one of these + distribution, please either use the recommended name or get back + to us explaining why you don't want to, so we can work out nomenclature + that will make users' lives easier rather than harder. + +RECENT XTERM VERSIONS + The terminfo database file included with this distribution assumes you + are running an XFree86 xterm based on X11R6 (i.e., xterm-r6). The + earlier X11R5 entry (xterm-r5) is provided as well. + + If you are running XFree86 version 3.2 (actually 3.1.2F and up), you + should consider using the xterm-xf86-v32 (or later, the most recent + version is always named "xterm-xfree86") entry, which adds ANSI color + and the VT220 capabilities which have been added in XFree86. If you + are running a mixed network, however, where this terminal description + may be used on an older xterm, you may have problems, since + applications that assume these capabilities will produce incorrect + output on the older xterm (e.g., highlighting is not cleared). + +CONFIGURING FALLBACK ENTRIES + In order to support operation of ncurses programs before the terminfo + tree is accessible (that is, in single-user mode or at OS installation + time) the ncurses library can be compiled to include an array of + pre-fetched fallback entries. + + These entries are checked by setupterm() only when the conventional + fetches from the terminfo tree and the termcap fallback (if configured) + have been tried and failed. Thus, the presence of a fallback will not + shadow modifications to the on-disk entry for the same type, when that + entry is accessible. + + By default, there are no entries on the fallback list. After you + have built the ncurses suite for the first time, you can change + the list (the process needs infocmp(1)). To do so, use the script + MKfallback.sh. A configure script option --with-fallbacks does this + (it accepts a comma-separated list of the names you wish, and does + not require a rebuild). + + If you wanted (say) to have linux, vt100, and xterm fallbacks, you + would use the commands + + cd ncurses; + MKfallback.sh linux vt100 xterm >fallback.c + + Then just rebuild and reinstall the library as you would normally. + You can restore the default empty fallback list with + + MKfallback.sh >fallback.c + + The overhead for an empty fallback list is one trivial stub function. + Any non-empty fallback list is const-ed and therefore lives in sharable + text space. You can look at the comment trailing each initializer in + the generated ncurses/fallback.c file to see the core cost of the + fallbacks. A good rule of thumb for modern vt100-like entries is that + each one will cost about 2.5K of text space. + +BSD CONVERSION NOTES: + If you need to support really ancient BSD programs, you probably + want to configure with the --enable-bsdpad option. What this does + is enable code in tputs() that recognizes a numeric prefix on a + capability as a request for that much trailing padding in milliseconds. + There are old BSD programs that do things like tputs("50"). + + (If you are distributing ncurses as a support-library component of + an application you probably want to put the remainder of this section + in the package README file.) + + The following note applies only if you have configured ncurses with + --enable-termcap. + +------------------------------- CUT HERE -------------------------------- + +If you are installing this application privately (either because you +have no root access or want to experiment with it before doing a root +installation), there are a couple of details you need to be aware of. +They have to do with the ncurses library, which uses terminfo rather +than termcap for describing terminal characteristics. + +Though the ncurses library is terminfo-based, it will interpret your +TERMCAP variable (if present), any local termcap files you reference +through it, and the system termcap file. However, in order to avoid +slowing down your application startup, it will only do this once per +terminal type! + +The first time you load a given terminal type from your termcap +database, the library initialization code will automatically write it +in terminfo format to a subdirectory under $HOME/.terminfo. After +that, the initialization code will find it there and do a (much +faster) terminfo fetch. + +Usually, all this means is that your home directory will silently grow +an invisible .terminfo subdirectory which will get filled in with +terminfo descriptions of terminal types as you invoke them. If anyone +ever installs a global terminfo tree on your system, this will quietly +stop happening and your $HOME/.terminfo will become redundant. + +The objective of all this logic is to make converting from BSD termcap +as painless as possible without slowing down your application (termcap +compilation is expensive). + +If you don't have a TERMCAP variable or custom personal termcap file, +you can skip the rest of this dissertation. + +If you *do* have a TERMCAP variable and/or a custom personal termcap file +that defines a terminal type, that definition will stop being visible +to this application after the first time you run it, because it will +instead see the terminfo entry that it wrote to $HOME/terminfo the +first time around. + +Subsequently, editing the TERMCAP variable or personal TERMCAP file +will have no effect unless you explicitly remove the terminfo entry +under $HOME/terminfo. If you do that, the entry will be recompiled +from your termcap resources the next time it is invoked. + +To avoid these complications, use infocmp(1) and tic(1) to edit the +terminfo directory directly. + +------------------------------- CUT HERE -------------------------------- + +USING NCURSES WITH AFS: + AFS treats each directory as a separate logical filesystem, you + can't hard-link across them. The --enable-symlinks option copes + with this by making tic use symbolic links. + +USING NCURSES WITH EMACS: + GNU Emacs has its own termcap support. By default, it uses a mixture + of those functions and code linked from the host system's libraries. + You need to foil this and shut out the GNU termcap library entirely. + + In order to do this, hack the Linux config file (s/linux.h) to contain + a #define TERMINFO and set the symbol LIBS_TERMCAP to "-lncurses". + + We have submitted such a change for the 19.30 release, so it may + already be applied in your sources -- check for the #define TERMINFO. + +USING NCURSES WITH GPM: + Ncurses 4.1 and up can be configured to use GPM (General Purpose Mouse) + which is used on Linux console. Be aware that GPM is commonly + installed as a shared library which contains a wrapper for the curses + wgetch() function (libcurses.o). Some integrators have simplified + linking applications by combining all of libcurses.so (the BSD curses) + into the libgpm.so file, producing symbol conflicts with ncurses. You + may be able to work around this problem by linking as follows: + + cc -o foo foo.o -lncurses -lgpm -lncurses + + but the linker may not cooperate, producing mysterious errors. + A patched version of gpm is available: + + ftp.clark.net:/pub/dickey/ncurses/gpm-1.10-970125.tgz + + This patch is incorporated in gpm 1.12; however some integrators + are slow to update this library. + +USING NCURSES WITH ELVIS: + To use ncurses as the screen-painting library for Elvis, apply the + following patch to the Elvis curses + +*** curses.c.orig Sun Jun 26 05:48:23 1994 +--- curses.c Sun Feb 11 16:50:41 1996 +*************** +*** 986,992 **** + { + if (has_IM) + do_IM(); +! do_IC(); + qaddch(ch); + if (has_EI) + do_EI(); +--- 986,995 ---- + { + if (has_IM) + do_IM(); +!#ifdef NCURSES_VERSION +! else /* ncurses does insertion in a slightly nonstandard way */ +!#endif +! do_IC(); + qaddch(ch); + if (has_EI) + do_EI(); + +This patch is for elvis-1.8pl4 but it can even be used for elvis-1.8pl3 with +an offset of -11 lines. + +BUGS: + Send any feedback to the ncurses mailing list at + bug-ncurses@gnu.org.

It has actually + nothing to with panels but is a problem in the implementation of + wrefresh(). Whenever a window changes its background attribute to + something different than newscr's background attribute, the whole + window is touched to force a copy to newscr. This is an unwanted + side-effect of wrefresh() and it is actually not necessary. A changed + background attribute affects only further outputs of background it + doesn't mean anything to the current content of the window. So there + is no need to force a copy. (reported by Frank Heckenbach + <frank@g-n-u.de>). + + an upward compatible enhancement of the NCursesPad class in the C++ + binding. It allows one to add a "viewport" window to a pad and then + to use panning to view the pad through the viewport window. + +990724 pre-release + + suppress a call to def_prog_mode() in the SIGTSTP handler if the + signal was received while not in curses mode, e.g., endwin() was + called in preparation for spawning a shell command (reported by Frank + Heckenbach <frank@g-n-u.de>) + + corrected/enhanced xterm-r5, xterm+sl, xterm+sl-twm terminfo entries. + + change test for xterm mouse capability: it now checks only if the + user's $DISPLAY variable is set in conjunction with the kmous + capability being present in the terminfo. Before, it checked if any + of "xterm", "rxvt" or "kterm" were substrings of the terminal name. + However, some emulators which are incompatible with xterm in other + ways do support the xterm mouse capability. + + reviewed and made minor changes in ncurses to quiet g++ warnings + about shadowed or uninitialized variables. g++ incorrectly warns + about uninitialized variables because it does not take into account + short-circuit expression evaluation. + + change ncurses 'b' test to start in color pair 0 and to show in the + right margin those attributes which are suppressed by no_color_video, + i.e., "(NCV)". + + modify ifdef's in curses.h so that __attribute__ is not redefined + when compiling with g++, but instead disabled the macros derived for + __attribute__ since g++ does not consistently recognize the same + keywords as gcc (reported by Stephan K Zitz <zitz@erf.net>). + + update dependencies for term.h in ncurses/modules (reported by + Ilya Zakharevich). + +990710 pre-release + + modify the form demo in ncurses.c to illustrate how to manipulate the + field appearance, e.g, for highlighting or translating the field + contents. + + correct logic in write_entry from split-out of home_terminfo in + 980919, which prevented update of $HOME/.terminfo (reported by Philip + Spencer <pspencer@fields.utoronto.ca>). + +990703 pre-release + + modify linux terminfo description to make use of kernel 2.2.x mods + that support cursor style, e.g., to implement cvvis (patch by Frank + Heckenbach <frank@g-n-u.de>) + + add special-case in setupterm to retain previously-saved terminal + settings in cur_term, which happens when curses and termcap calls are + mixed (from report by Bjorn Helgaas <helgaas@dhc.net>). + + suppress initialization of key-tries in _nc_keypad() if we are only + disabling keypad mode, e.g., in endwin() called when keypad() was not. + + modify the Ada95 makefile to ensure that always the Ada files from + the development tree are used for building and not the eventually + installed ones (patch by Juergen Pfeifer). + +990626 pre-release + + use TTY definition in tack/sysdep.c rather than struct termios + (reported by Philippe De Muyter). + + add a fallback for strstr, used in lib_mvcur.c and tack/edit.c, + not present on sysV68 (reported by Philippe De Muyter). + + correct definition in comp_hash.c to build with configure + --with-rcs-ids option. + +990619 pre-release + + modified ifdef's for sigaction and sigvec to ensure we do not try to + handle SIGTSTP if neither is available (from report by Philippe De + Muyter). + > patch by Philippe De Muyter: + + in tic.c, use `unlink' if `remove' is not available. + + use only `unsigned' as fallback value for `speed_t'.

The internal SLK + state is stored in the SCREEN struct after every newterm() and then + reset for the next newterm. + + fix the problem that a slk_refresh() refreshes stdscr if the + terminal has true SLKs. + + update HTML documentation for Ada binding. + +990301 pre-release + + remove 'bool' casts from definitions of TRUE/FALSE so that statements + such as "#if TRUE" work. This was originally done to allow for a C++ + compiler which would warn of implicit conversions between enum and + int, but is not needed for g++ (reported by Kim DeVaughn). + + add use_extended_names() function to allow applications to suppress + read of the extended capabilities. + + add configure option --enable-tcap-names to support logic which + allows ncurses' tic to define new (i.e., extended) terminal + capabilities. This is activated by the tic -x switch. The infocmp + program automatically shows or compares extended capabilities. + Note: This changes the Strings and similar arrays in the TERMTYPE + struct so that applications which manipulate it must be recompiled. + + use macros typeMalloc, typeCalloc and typeRealloc consistently + throughout ncurses library. + + add _nc_strdup() to doalloc.c. + + modify define_key() to allow multiple strings to be bound to the + same keycode. + + correct logic error in _nc_remove_string, from 990220. + > patch by Juergen Pfeifer, for Ada95 binding: + + regenerate some of the html documentation + + minor cleanup in terminal_interface-curses.adb + +990220 pre-release + + resolve ambiguity of kend/kll/kslt and khome/kfnd/kich1 strings in + xterm and ncsa terminfo entries by removing the unneeded ones.

This is shown only if + the verbose (-v) option is given. Moved related logic (tic -v) from + comp_parse.c into the tic program. + + add/use _nc_trace_tries() to show the function keys that will be + recognized. + + rename init_acs to _nc_init_acs (request by Alexander Lukyanov). + > patch by Juergen Pfeifer, for Ada95 binding: + + remove all the *_adabind.c from ncurses, menu and form projects. + Those little helper routines have all been implemented in Ada and are + no longer required. + + The option handling routines in menu and form have been made more + save. They now make sure that the unused bits in options are always + zero. + + modify configuration scripts to + + use gnatmake as default compiler name.

This affects only scrolling optimization, to fix a + problem reported by several people with xterm's alternate screen, + though the problem is more general. + > patch by Juergen Pfeifer, for Ada95 binding: + + removed all pragma Preelaborate() stuff, because the just released + gnat-3.11p complains on some constructs. + + fixed some upper/lower case notations because gnat-3.11p found + inconsistent use. + + used a new method to generate the HTML documentation of the Ada95 + binding. This invalidates nearly the whole ./Ada95/html subtree. + Nearly all current files in this subtree are removed + +990130 + + cache last result from _nc_baudrate, for performance (suggested by + Alexander Lukyanov). + + modify ClrUpdate() function to workaround a problem in nvi, which + uses redrawwin in SIGTSTP handling.

Dickey + +### ncurses 1.8.6 -> 1.8.7 +* cleaned up programs in test/ directory. +* fixed wbkgdset() macro. +* modified getstr() to stop it from advancing cursor in noecho mode. +* modified linux terminfo entry to work with the latest kernel to get + the correct alternate character set. +* also added a linux-mono entry for those running on monochrome screens. +* changed initscr() so that it behaves like the man page says it does. + this fixes the problem with programs in test/ crashing with SIGSEV if + a terminal is undefined. +* modified addch() to avoid using any term.h #define's +* removed duplicate tgoto() in lib_tparm.c +* modified dump_entry.c so that infocmp deals correctly with ',' in acsc +* modified delwin() to correctly handle deleting subwindows. +* fixed Makefile.dist to stop installing an empty curses.h +* fixed a couple of out-of-date notes in man pages. + +### ncurses 1.8.5 -> 1.8.6 +* Implemented wbkgd(), bkgd(), bkgdset(), and wbkgdset(). +* The handling of attributes has been improved and now does not turn off color + if other attributes are turned off. +* scrolling code is improved. Scrolling in subwindows is still broken. +* Fixes to several bugs that manifest them on platforms other than Linux. +* The default to meta now depends on the status of the terminal when ncurses + is started. +* The interface to the tracing facility has changed. Instead of the pair of + functions traceon() and traceoff(), there is just one function trace() which + takes a trace mask argument. The trace masks, defined in curses.h, are + as follows: + + #define TRACE_DISABLE 0x00 /* turn off tracing */ + #define TRACE_ORDINARY 0x01 /* ordinary trace mode */ + #define TRACE_CHARPUT 0x02 /* also trace all character outputs */ + #define TRACE_MAXIMUM 0x0f /* maximum trace level */ + + More trace masks may be added, or these may be changed, in future releases. +* The pad code has been improved and the pad test code in test/ncurses.c has + been improved. +* The prototype ansi entry has been changed to work with a wider variety + of emulators. +* Fix to the prototype ansi entry that enables it to work with PC emulators + that treat trailing ";m" in a highlight sequence as ";0m"; this doesn't + break operation with any emulators. +* There are now working infocmp, captoinfo, tput, and tclear utilities. +* tic can now compile entries in termcap syntax. +* Core-dump bug in pnoutrefresh fixed. +* We now recognize and compile all the nonstandard capabilities in Ross + Ridge's mytinfo package (rendering it obsolete). +* General cleanup and documentation improvements. +* Fixes and additions to the installation-documentation files. +* Take cursor to normal mode on endwin. + +### ncurses 1.8.4 -> 1.8.5 +* serious bugs in updating screen which caused erratic non-display, + fixed. +* fixed initialization for getch() related variable which cause + unpredictable results. +* fixed another doupdate bug which only appeared if you have + parm_char. +* implemented redrawln() and redrawwin(). +* implemented winsnstr() and related functions. +* cleaned up insertln() and deleteln() and implemented (w)insdeln(). +* changed Makefile.dist so that installation of man pages will + take note of the terminfo directory. +* fixed Configure (removed the mysterious 'X'). +* Eric S. Raymond fixed the script.* files so that they work with + stock awk. + +#### ncurses 1.8.3 -> 1.8.4 #### #### +* fixed bug in refreshing the screen after return from shell_mode. + There are still problems but they don't manifest themselves on + my machine (Linux 0.99.14f). +* added wgetnstr() and modified things accordingly. +* fixed the script.src script.test to work with awk not just gawk. +* Configure can now take an argument of the target system. +* added test/ncurses.c which replaces several other programs and + performs more testing. +[Thanks to Eric S Raymond for the last 4] +* more fixes to lib_overlay.c and added test/over.c to illustrate + how it works. +* fixed ungetch() to take int instead of ch. +* fixes to cure wgetch() if flushinp() is called. + +One note I forgot to mention in 1.8.3 is that tracing is off by +default starting in the version. If you want tracing output, put +traceon(); in your code and link with -ldcurses. + +#### ncurses 1.8.2 -> ncurses 1.8.3 #### #### +MAJOR CHANGES: +1) The order of capabilities has been changed in order to achieve +binary compatibility with SVR4 terminfo database. This has the +unfortunate effect of breaking application currently linked with +ncurses. To ensure correct behavior, recompile all such programs. +Most programs using color or newer capabilities will break, others +will probably continue to work ok. + +2) Pavel Curtis has renounced his copyright to the public domain. +This means that his original sources (posted to comp.sources.unix, +volume 1) are now in the public domain. The current sources are +NOT in the public domain, they are copyrighted by me. I'm +entertaining ideas on what the new terms ncurses is released under. + +3) Eric S. Raymond has supplied a complete set of man pages for +ncurses in ?roff format. They will eventually replace most of the +current docs. Both sets are included in this release. + +Other changes and notes from 1.8.2 include: +* SIGSEGV during scrolling no longer occurs. +* Other problems with scrolling and use of idl have been corrected. +* lib_getch.c has been re-written and should perform flawlessly. + please use test/getch.c and any other programs to test this. +* ripoffline() is implemented (Thanks to Eric) and slk_ functions + changed accordingly. +* I've added support for terminals that scroll if you write in the + bottom-right corner. +* fixed more bugs in pads code. If anybody has a program that uses + pads I'd love a copy. +* correct handling for terminal with back_color_erase capability + (such as Linux console, and most PC terminals) +* ^Z handling apparently didn't work (I should never trust code + sent me to me without extensive testing). It now seems to be + fixed. Let me know if you have problems. +* I've added support for Apollo and NeXT, but it may still be + incomplete, especially when dealing with the lack of POSIX + features. +* scrolling should be more efficient on terminals with idl + capabilities. Please see src/lib_scroll.c for more notes. +* The line drawing routines were offset by 1 at both ends. This + is now fixed. +* added a few missing prototypes and macros (e.g. setterm()) +* fixed code in src/lib_overlay.c which used to crash. +* added a few more programs in test/ The ones from the PDCurses + package are useful, especially if you have SVR4 proper. I'm + interested in the results you get on such a systems (Eric? ;-). + They already exposed certain bugs in ncurses. +* See src/README for porting notes. +* The C++ code should really replace ncurses.h instead of working + around it. It should avoid name-space clashes with nterm.h (use + rows instead of lines, etc.) +* The C++ should compile ok. I've added explicit rules to the + Makefile because no C++ defaults are documented on the suns. +* The docs say that echo() and nocbreak() are mutually exclusive. + At the moment ncurses will switch to cbreak() if the case above + occurs. Should it continue to do so? How about echo() and noraw()? +* PDCurses seem to assume that wclear() will use current attribute + when clearing the screen. According to Eric this is not the case + with SVR4. +* I have discovered, to my chagrin, SunOS 4.x (and probably other systems) + * doesn't have vsscanf and God knows what else! I've will do a vsscanf(). +* I've also found out that the src/script.* rely on gawk and will not + work with stock awk or even with nawk. Any changes are welcome. +* Linux is more tolerant of NULL dereferences than most systems. This + fact was exposed by hanoi. +* ncurses still seems inefficient in drawing the screen on a serial + link between Linux and suns. The padding may be the culprit. +* There seems to be one lingering problem with doupdate() after shelling + out. Despite the fact the it is sending out the correct information + to the terminal, nothing takes effect until you press ^L or another + refresh takes place. And yes, output does get flushed. + +#### ncurses 1.8.1 -> ncurses 1.8.2 #### Nov 28, 1993 #### + +* added support for SVR4 and BSDI's BSD/386. +* major update and fix to scrolling routine. +* MORE fixes to stuff in lib_getch.c. +* cleaned-up configuration options and can now generate + Config.* files through an awk script. +* changed setupterm() so it can be called more than once, + add added set_curterm(), del_curterm(). +* a few minor cleanups. +* added more prototypes in curses.h + +#### ncurses 1.8 -> ncurses 1.8.1 #### Nov 4, 1993 #### + +* added support for NeXTStep 3.0 +* added termcap emulation (not well tested). +* more complete C++ interface to ncurses. +* fixed overlay(), overwrite(), and added copywin(). +* a couple of bug fixes. +* a few code cleanups. + +#### ncurses 0.7.2/0.7.3 -> ncurses 1.8 #### Aug 31, 1993 #### + +* The annoying message "can't open file." was due to missing + terminfo entry for the used terminal. It has now been + replaced by a hopefully more helpful message. +* Problems with running on serial lines are now fixed. +* Added configuration files for SunOS, Linux, HP/UX, Ultrix, + 386bsd/BSDI (if you have others send'em to me) +* Cleaner Makefile. +* The documentation in manual.doc is now more uptodate. +* update optimization and support for hp terminals, and 386bsd + console driver(s). +* mvcur optimization for terminals without cursor addressing + (doesn't work on Linux) +* if cursor moved since last update, getch() will refresh the + screen before working. +* getch() & alarm() can now live together. in 0.7.3 a signal + interrupted getch() (bug or feature?) now the getch is + restarted. +* scanw() et all were sick, now fixed. +* support for 8-bit input (use meta()). +* added default screen size to all terminfos. +* added c++ Ncursesw class. +* several minor bug fixes. + +#### ncurses 0.7.2 -> ncurses 0.7.3 #### May 27, 1993 #### + +* Config file to cope with different platforms (386BSD, BSDI, Ultrix, SunOS) +* more fixes to lib_getch.c +* changes related to Config + +#### ncurses 0.7 -> ncurses 0.7.2 #### May 22, 1993 #### + +* docs updated slightly (color usage is now documented). +* yet another fix for getch(), this one fixes problems with ESC being swallowed + if another character is typed before the 1 second timeout. +* Hopefully, addstr() and addch() are 8-bit clean. +* fixed lib_tparm.c to use stdarg.h (should run on suns now) +* order of capabilities changed to reflect that specified in SYSV + this will allow for binary-compatibility with existing terminfo dbs. +* added halfdelay() +* fixed problems with asc_init() +* added A_PROTECT and A_INVIS +* cleaned up vidputs() +* general cleanup of the code +* more attention to portability to other systems +* added terminfos for hp70092 (wont work until changes to lib_update.c are + made) and 386BSD pcvt drivers. + +Thanks to Hellmuth Michaelis for his help. +optimization code is slated for the next major release, stay tuned! + +#### ncurses 0.6/0.61 -> ncurses 0.7 #### April 1, 1993 +Please note that the next release will be called 1.8. If you want to know about +the rationale drop me a line. + +Included are several test programs in test/. +I've split up the panels library, reversi, tetris, sokoban. They are now +available separately from netcom.com:pub/zmbenhal/ + +* color and ACS support is now fully compatible with SYSV at the terminfo + level. +* Capabilities now includes as many SYSV caps I could find. +* tigetflag,tigetnum,tigetstr functions added. +* boolnames, boolfnames, boolcodes numnames, numfnames, numcodes, + strnames, strfnames, strcodes arrays are now added. +* keyname() is added. +* All function keys can be defined in terminfo entries. +* fixed lin_tparm.c to behave properly. +* terminfo entries for vt* and xterm are included (improvements are welcome) +* more automation in handling caps and keys. +* included fixes from 0.6.1 +* added a few more missing functions. +* fixed a couple of minor bugs. +* updated docs JUST a little (still miles behind in documenting the newer + features). + +#### ncurses 0.6 -> ncurses 0.61 #### + +1) Included the missing data/console. + +2) allow attributes when drawing boxes. + +3) corrected usage of win->_delay value. + +4) fixed a bug in lib_getch.c. if it didn't recognize a sequence it would + simply return the last character in the sequence. The correct + behavior is to return the entire sequence one character at a time. + +#### ncurses0.5 -> ncurses0.6 #### March 1, 1993 #### +* removed _numchngd from struct _win_st and made appropriate changes. +* rewritten kgetch() to remove problems with interaction between alarm and + read().

There should be a number of subdirectories, including `c++', `form', +`man', `menu', `misc', `ncurses', `panel', `progs', `test', 'tack' and `Ada95'. +(The 'tack' program is distributed separately). + +A full build/install of this package typically installs several libraries, a +handful of utilities, and a database hierarchy. Here is an inventory of the +pieces: + +The libraries are: + + libncurses.a (normal) + libncurses.so (shared) + libncurses_g.a (debug and trace code enabled) + libncurses_p.a (profiling enabled) + + libpanel.a (normal) + libpanel.so (shared) + libpanel_g.a (debug and trace code enabled) + + libmenu.a (normal) + libmenu.so (shared) + libmenu_g.a (debug enabled) + + libform.a (normal) + libform.so (shared) + libform_g.a (debug enabled) + +The ncurses libraries implement the curses API. The panel, menu and forms +libraries implement clones of the SVr4 panel, menu and forms APIs. The source +code for these lives in the `ncurses', `panel', `menu', and `form' directories +respectively. + +In the `c++' directory, you'll find code that defines an interface to the +curses, forms, menus and panels library packaged as C++ classes, and a demo program in C++ +to test it. These class definition modules are not installed by the 'make +install.libs' rule as libncurses++. + +In the `Ada95' directory, you'll find code and documentation for an +Ada95 binding of the curses API, to be used with the GNAT compiler. +This binding is built by a normal top-level `make' if configure detects +an usable version of GNAT (3.10 or above). It is not installed automatically. +See the Ada95 directory for more build and installation instructions and +for documentation of the binding. + +To do its job, the ncurses code needs your terminal type to be set in the +environment variable TERM (normally set by your OS; under UNIX, getty(1) +typically does this, but you can override it in your .profile); and, it needs a +database of terminal descriptions in which to look up your terminal type's +capabilities. + +In older (V7/BSD) versions of curses, the database was a flat text file, +/etc/termcap; in newer (USG/USL) versions, the database is a hierarchy of +fast-loading binary description blocks under /usr/lib/terminfo. These binary +blocks are compiled from an improved editable text representation called +`terminfo' format (documented in man/terminfo.5). The ncurses library can use +either /etc/termcap or the compiled binary terminfo blocks, but prefers the +second form. + +In the `misc' directory, there is a text file terminfo.src, in editable +terminfo format, which can be used to generate the terminfo binaries (that's +what make install.data does). If the package was built with the +--enable-termcap option enabled, and the ncurses library cannot find a terminfo +description for your terminal, it will fall back to the termcap file supplied +with your system (which the ncurses package installation leaves strictly +alone). + +The utilities are as follows: + + tic -- terminfo source to binary compiler + infocmp -- terminfo binary to source decompiler/comparator + clear -- emits clear-screen for current terminal + tput -- shell-script access to terminal capabilities. + toe -- table of entries utility + tset -- terminal-initialization utility + +The first two (tic and infocmp) are used for manipulating terminfo +descriptions; the next two (clear and tput) are for use in shell scripts. The +last (tset) is provided for 4.4BSD compatibility. The source code for all of +these lives in the `progs' directory. + +Detailed documentation for all libraries and utilities can be found in +the `man' directory. An HTML introduction to ncurses, panels, and +menus programming lives in the `misc' directory. Manpages in HTML format +are under `Ada95/html'. + +The `test' directory contains programs that can be used to verify or +demonstrate the functions of the ncurses libraries. See test/README for +descriptions of these programs. Notably, the `ncurses' utility is designed to +help you systematically exercise the library functions. + +AUTHORS: + +Pavel Curtis: + wrote the original ncurses + +Zeyd M.

You will not see + this problem if you are running Linux or one of the 4.4BSD derivatives + like FreeBSD, NetBSD, or BSDI. For details, see the analysis in the + header comment of ncurses/lib_tstp.c. + +* In theory, vwprintw and vwscanf are supposed to use the older varargs.h + interface for handling variadic argument lists. Linux doesn't have + varargs.h, it has the newer X/Open-standard stdargs.h equivalent. So + these functions use stdargs instead. This is unlikely to be a problem + unless you're building ncurses on a System V old enough to only have + varargs.h.

From the AT&T termcap file it looks like curses, in general, +shouldn't use them; terminal variants with status lines have their line count +decremented by 1, suggesting that curses is supposed to leave the status line +alone. + +B.

Printer-control capabilities: + + Boolean: prtr_silent. + Strings: print_screen, prtr_on, prtr_off, prtr_non. + +Curses doesn't use these. + +D. Dialer strings: + + Strings: hangup, dial_phone, quick_dial, tone, pulse, flash_hook, + fixed_pause, wait_tone. + +Curses doesn't use these. + +E. Window and virtual-terminal capabilities: + + Numerics: maximum_windows, virtual_terminal. + Strings: req_for_input, create_window, goto_window, set_window. + +These seem to be fossils from some AT&T experiments on character-based +window systems that never escaped the lab. The virtual_terminal cap had +something to do with building terminal emulations into tty line disciplines. + +F. Unused VDT capabilities: + + Booleans: erase_overstrike, has_meta_key, insert_null_glitch, + move_insert, dest_tabs_magic_smso, transparent_underline, + needs_xon_xoff, hard_cursor. + Numerics: lines_of_memory, buttons. + Strings: pkey_key, pkey_local, pkey_xmit, underline_char, + enter_xon_mode, exit_xon_mode, xon_character, xoff_character, + display_clock, remove_clock, user[0-5], display_pc_char, + enter_scancode_mode, exit_scancode_mode, pc_term_options, + scancode_escape, alt_scancode_esc. + +These are the potentially important ones for ncurses. Notes: + + i) ncurses doesn't need move_insert; it never uses cup/hpa/vpa while + insert_mode is on. + + ii) We probably don't care about dest_tabs_magic_smso; only + Telerays used it and they're all long obsolete. + + diff --git a/contrib/ncurses/aclocal.m4 b/contrib/ncurses/aclocal.m4 new file mode 100644 index 000000000000..b42625d46df4 --- /dev/null +++ b/contrib/ncurses/aclocal.m4 @@ -0,0 +1,2140 @@ +dnl*************************************************************************** +dnl Copyright (c) 1998 Free Software Foundation, Inc. * +dnl * +dnl Permission is hereby granted, free of charge, to any person obtaining a * +dnl copy of this software and associated documentation files (the * +dnl "Software"), to deal in the Software without restriction, including * +dnl without limitation the rights to use, copy, modify, merge, publish, * +dnl distribute, distribute with modifications, sublicense, and/or sell * +dnl copies of the Software, and to permit persons to whom the Software is * +dnl furnished to do so, subject to the following conditions: * +dnl * +dnl The above copyright notice and this permission notice shall be included * +dnl in all copies or substantial portions of the Software. * +dnl * +dnl THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS * +dnl OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF * +dnl MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. * +dnl IN NO EVENT SHALL THE ABOVE COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, * +dnl DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT OR * +dnl OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR * +dnl THE USE OR OTHER DEALINGS IN THE SOFTWARE. * +dnl * +dnl Except as contained in this notice, the name(s) of the above copyright * +dnl holders shall not be used in advertising or otherwise to promote the * +dnl sale, use or other dealings in this Software without prior written * +dnl authorization. * +dnl*************************************************************************** +dnl +dnl Author: Thomas E.

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">ftp://ftp.gnu.org/pub/gnu</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>change key_names[] array to static 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.

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>change key_names[] array to static 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.

The code is derived +from the libg++ CursesWindow class but enhanced for ncurses. + +The classes simplify the use of window specific functions by +encapsulating them in the window object. Function overloading is +used in order to narrow the interface. E.g. you don't have the +distinction between `printw' and `mvprintw' anymore. + +A second benefit is the removal of all #defines which are included in +the curses.h file. This is a steady cause of trouble because many +common identifiers are used. Instead now all #defines are inline +functions which also allows strict type checking of arguments. + +The next enhancement is color support. It was originally provided by a +derived class. This caused some trouble if you think about Panels or +Menus and Forms with colors. We decided to put color support into the +base class so that any derived class may use color support also. +The implementation chosen here is directed to unrestricted use +of mixes of color and monochrome windows. The original NCursesColorWindow +class is maintained for compatibility reasons. + +The last point to mention is the support of other packages that are +distributed with the ncurses package: the panels library, the menu library +and the form library. This support is provided by the NCursesPanel class, +which is also derived from the NCursesWindow class and the NCursesMenu +and NCursesForm classes which are derived from NCursesPanel. This allows +building interfaces with windows. + +Please see the example program for a quick introduction. + +Note that at this point, there is no documentation for these classes. +Hopefully some will be written in the not too distant future. For now, +to find out how to use the classes, read the code and the example program. + +Suggestions for enhancements and contributions of code (and docs) are +welcome. Please let us know which functionality you miss. + + ATTENTION LINUX USERS: There is currently some discussion of + replacing the BSD curses in the Linux libc with ncurses. If + this is done we could perhaps include these classes in the Linux + libg++ replacing the original CursesWindow class (and renaming it + to CursesWindow).
