These are the highlights from the change-log -since ncurses 4.2 release. +This release is designed to be upward compatible from ncurses 5.0; very few +applications will require recompilation, depending on the platform. +These are the highlights from the change-log since ncurses 5.0 release. <p> Interface changes: <ul> - <li>The principal source of changes to the interface comes from the - release of X/Open Curses in 1997. Earlier versions of ncurses (4.0 - and before) were based on a draft version of the specification. The - release version adds parameters to some functions to support the - evolving internationalization of curses. These summarize the impact: -<ul> - <li>modified several prototypes to correspond with 1997 version of - X/Open Curses (affects ABI since developers have used attr_get). - - <li>corrected prototypes for slk_* functions, using chtype rather than - attr_t. - - <li>the slk_attr_{set,off,on} functions need an additional void* - parameter according to XSI. - - <li>correct macros for wattr_set, wattr_get, separate wattrset macro from - these to preserve behavior that allows attributes to be combined with - color pair numbers. - - <li>reviewed/updated curses.h, term.h against X/Open Curses Issue 4 - Version 2. This includes making some parameters NCURSES_CONST - rather than const, e.g., in termcap.h. - - <li>reviewed/corrected macros in curses.h as per XSI document. - - <li>add set_a_attributes and set_pglen_inch to terminfo structure, as per - XSI and Solaris 2.5. -</ul> - <li>The newest version of the X/Open Curses is implemented on Solaris - and other vendor's systems. It adds new features to the terminfo - descriptions: -<ul> - <li>implement tparm %l format. - - <li>implement tparm printf-style width and precision for %s, %d, %x, %o - as per XSI. -</ul> - <li>We made additional changes to reduce impact by future interface - changes: -<ul> - <li>rename key_names[] array to _nc_key_names since it is not part of - the curses interface. - - <li>move macro winch to a function, to hide details of struct ldat -</ul> - <li>modify configure script to embed ABI in shared libraries for HP-UX - 10.x (detailed request by Tim Mooney). - - <li>modify configuration of shared libraries on Digital Unix so that - versioning is embedded in the library, rather than implied by - links (patch by Tim Mooney). + <li>made the extended terminal capabilities + (<code>configure --enable-tcap-names</code>) + a standard feature (though the configure script can disable it, + it is built by default). + + <li>removed the <code>trace()</code> function and related trace support + from the production library. This is the only interface change that + may cause problems with existing applications linked to shared + libraries, since not all platforms use the minor version number. + + <li>explicitly initialized to zero several data items which were + implicitly initialized, e.g., cur_term. If not explicitly + initialized, their storage type is C (common), and causes problems + linking on some platforms. + + <li>modified curses.h.in, undef'ing some symbols to avoid conflict with + C++ STL. </ul> New features: <ul> - <li>enable sigwinch handler by default. + <li>added a new extension, <code>assume_default_colors()</code> to + provide better control over the use of default colors. This is + the principal visible difference between ncurses 5.1 and preceding + versions. The new extension allows an application to specify what + colors pair 0 uses. It defaults to white on black, unless you + have invoked <code>use_default_colors()</code>. + + <li>made several fixes to the terminfo-to-termcap conversion, and + have been using the generated termcaps without further hand-tuning. + This builds on the extension <code>use_extended_names()</code> by + adding "obsolete" termcap strings to terminfo.src + <ul> + <li>modified <code>tic</code> so that if extended names (i.e., + configure --enable-tcap-names) are active, then <code>tic -x</code> + will also write "obsolete" capabilities that are present in the + terminfo source. + + <li>added screen's AX capability (for ECMA SGR 39 and 49) to applicable + terminfo entries, use presence of this as a check for a small + improvement in setting default colors. + + <li>add -a option to tic and infocmp, which retains commented-out + capabilities during source translation/comparison, e.g., captoinfo + and infotocap. + </ul> + + <li>implemented limited support for UTF-8, useful with XFree86 xterm: + <ul> + <li>if the <code>configure --enable-widec</code> option is + given, append 'w' to names of the generated libraries (e.g., + libncursesw.so) to avoid conflict with existing ncurses libraries. + <li>add a simple UTF-8 output driver to the experimental + wide-character support. If any of the environment variables + LC_ALL, LC_CTYPE or LANG contain the string "UTF-8", this driver + will be used to translate the output to UTF-8. + <li>modified view.c to make a rudimentary viewer of UTF-8 text. + </ul> + + <li>modify <code>raw()</code> and <code>noraw()</code> to clear/restore + IEXTEN flag which affects stty lnext on systems such as FreeBSD + + <li>reordered tests during mouse initialization to allow for gpm to run in + xterm, or for xterm to be used under OS/2 EMX. Also dropped test for + $DISPLAY in favor of kmous=\E[M or $TERM containing "xterm". + + <li>added configure option <code>--with-manpage-symlinks</code>, which + provides for fully indexing manpage entries by making symbolic links + for the aliases. + + <li>changed <code>unctrl()</code> to render C1 characters (128-159) as + <code>~@</code>, <code>~A</code>, etc. + + <li>add experimental configure option --enable-colorfgbg to check for + $COLORTERM variable as set by rxvt/aterm/Eterm. + + <li>made the <code>infocmp -F</code> option less verbose. + + <li>dropped support for gnat 3.10 (gnat 3.12 is current). - <li>turn on hashmap scrolling code by default - - <li>improved support for termcap applications +</ul> +Major bug fixes: <ul> - <li>modify tput to accept termcap names as an alternative to terminfo - names. + <li>modified infocmp -e, -E options to ensure that generated fallback.c + type for Booleans agrees with term.h - <li>provide support for termcap PC variable by copying it from terminfo - data and using it as the padding character in tputs. + <li>documented a special case of incompatiblity between ncurses 4.2 and + 5.0, added a section for this in INSTALL. - <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>corrected tests for file-descriptors in OS/2 EMX mouse support. A + negative value could be used by FD_SET, causing the select() call to + wait indefinitely. - <li>change name-comparisons in lib_termcap to compare no more than 2 - characters. + <li>made 'tput flash' work properly for xterm by flushing output in + delay_output() when using napms(), and modifying xterm's terminfo to + specify no padding character. Otherwise, xterm's reported baud rate + could mislead ncurses into producing too few padding 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>modified lib_addch.c to allow repeated update to the lower-right + corner, rather than displaying only the first character written until + the cursor is moved. Recent versions of SVr4 curses can update the + lower-right corner, and behave this way. - <li>modify terminfo parsing to accept octal and hexadecimal constants + <li>modified echo() behavior of getch() to match Solaris curses for + carriage return and backspace (reported by Neil Zanella). - <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>corrected offsets used for subwindows in <code>wresize()</code> - <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>modified configure script so AC_MSG_ERROR is temporarily defined to + a warning in AC_PROG_CXX to make it recover from a missing C++ + compiler without requiring user to add --without-cxx option - <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>corrected logic in lib_twait.c as used by lib_mouse.c for GPM mouse + support when poll() is used rather than select(). - <li>modify tic to compile into %'char' form in preference to %{number}, - since that is a little more efficient. -</ul> -Major bug fixes: -<ul> - <li>modify lib_tstp.c to block SIGTTOU when handling SIGTSTP, fixes a - problem where ncurses applications which were run via a shell script - would hang when given a ^Z. Also, check if the terminal's process - group is consistent, i.e., a shell has not taken ownership of it, - before deciding to save the current terminal settings in the SIGTSTP - handler. - - <li>suppress sc/rc capabilities from terminal description if they appear - in smcup/rmcup. This affects only scrolling optimization, to fix a - problem reported by several people with xterm's alternate screen, - though the problem is more general. - - <li>modify relative_move and tputs to avoid an interaction with the - BSD-style padding. The relative_move function could produce a string - to replace on the screen which began with a numeric character, which - was then interpreted by tputs as padding. - - <li>modify setupterm so that cancelled strings are treated the same as - absent strings, cancelled and absent booleans false (does not affect - tic, infocmp). - - <li>modify lib_vidattr.c to allow for terminal types (e.g., xterm-color) - which may reset all attributes in the 'op' capability, so that colors - are set before turning on bold and other attributes, but still after - turning attributes off. - - <li>use 'access()' to check if ncurses library should be permitted to - open or modify files with fopen/open/link/unlink/remove calls, in - case the calling application is running in setuid mode. - - <li>correction to doupdate, for case where terminal does not support - insert/delete character. The logic did not check that there was a - difference in alignment of changes to old/new screens before - repainting the whole non-blank portion of the line. Modified to fall - through into logic that reduces by the portion which does not differ. + <li>made several fixes for buffer overflows, unchecked recursion, + improvements in performance, etc. See the NEWS file for details. </ul> <H1>Features of Ncurses</H1> @@ -294,27 +274,36 @@ including (versions starting with those noted): <DL> <DT> cdk <DD> Curses Development Kit +<br> <A HREF="http://www.vexus.ca/CDK.html">Curses Development Kit</a> -<A HREF="ftp://ftp.clark.net/pub/dickey/cdk">ftp://ftp.clark.net/pub/dickey/cdk</A>. +<A HREF="http://dickey.his.com/cdk/cdk.html">http://dickey.his.com/cdk</A>. <DT> ded <DD> directory-editor -<A HREF="ftp://ftp.clark.net/pub/dickey/ded">ftp://ftp.clark.net/pub/dickey/ded</A>. +<br> +<A HREF="http://dickey.his.com/ded/ded.html">http://dickey.his.com/ded</A>. <DT> dialog <DD> the underlying application used in Slackware's setup, and the basis for similar applications on GNU/Linux. +<br> +<A HREF="http://dickey.his.com/dialog/dialog.html">http://dickey.his.com/dialog</A>. <DT> lynx <DD> the character-screen WWW browser +<br> +<A HREF="http://lynx.isc.org/release/">http://lynx.isc.org/release</A>. <DT> Midnight Commander 4.1 <DD> file manager <DT> mutt <DD> mail utility +<br> +<A HREF="http://www.mutt.org">http://www.mutt.org</A>. <DT> ncftp <DD> file-transfer utility <DT> nvi <DD> New vi versions 1.50 are able to use ncurses versions 1.9.7 and later. <DT> tin <DD> newsreader, supporting color, MIME -<A HREF="ftp://ftp.akk.uni-karlsruhe.de/pub/news/clients/tin-unoff">ftp://ftp.akk.uni-karlsruhe.de/pub/news/clients/tin-unoff</A>. +<br> +<A HREF="http://www.tin.org">http://www.tin.org</A>. <DT> taper <DD> tape archive utility <DT> vh-1.6 @@ -326,7 +315,8 @@ as well as some that use ncurses for the terminfo support alone: <DD> terminal emulator <DT> vile <DD> vi-like-emacs -<A HREF="ftp://ftp.clark.net/pub/dickey/vile">ftp://ftp.clark.net/pub/dickey/vile</A>. +<br> +<A HREF="http://dickey.his.com/vile/vile.html">http://dickey.his.com/vile</A>. </DL> <P> @@ -339,10 +329,10 @@ The original developers of ncurses are <A HREF="mailto:zmbenhal@netcom.com">Zeyd Ben-Halim</A> and <A HREF="http://www.ccil.org/~esr/home.html">Eric S.
