Hi... Is there any underlying reason why we can't upgrade Ncurses from 1.8.4 (circa 1994) to 1.9.9e (circa current)? Included at the bottom of this is the NEWS file from 1.9.9e listing changes since 1.8.4... If its a matter of someone integrating...I raise my hand... for me it means that its one less thing I have to remember not to install when I do a make world, so its worth my time commiting an upgrade and maintaining the library :) Marc G. Fournier scrappy@ki.net Systems Administrator @ ki.net scrappy@freebsd.org This is a log of changes that ncurses has gone through since I started working with Pavel Curtis' original work, pcurses, in 1992: ### ncurses-1.9.8a -> 1.9.9 * fixed broken wsyncup()/wysncdown(), as a result wnoutrefresh() now has copy-changed-lines behavior. * added and documented wresize() function. * more fixes to LOWER-RIGHT corner handling. * changed the line-breakout optimization code to allow some lines to be emitted before the first check. # added option for tic to use symbolic instead of hard links (for AFS) * fix to restore auto-wrap mode. * trace level can be controlled by environment variable. * better handling of NULs in terminal descriptions. * improved compatibility with observed SVR4 behavior. * the refresh behavior of over-lapping windows is now more efficient and behaves like SVR4. * use autoconf 2.7, which results in a working setup for SCO 5.0. * support for ESCDELAY. * small fixes for menu/form code. * the test directory has its own configure. * fixes to pads when optimizing scrolling. * fixed several off-by-one bugs. * fixes for termcap->terminfo translation; less restrictions more correct behavior. ### ncurses-1.9.7 -> 1.9.8a * teach infocmp -i to recognize ECMA highlight sequences * infocmp now dumps all SVr4 termcaps (not just the SVr4 ones) on -C * support infocmp -RBSD. * satisfy XSI Curses requirement that every macro be available as a function. * This represents the last big change to the public interface of ncurses. The ABI_VERSION has now been set at 3.0 and should stay there barring any great catastrophies or acts of God. * The C++ has been cleaned up in reaction to the changes to satisfy XSI's requirements. * libncurses now gets linked to libcurses to help seemless emulation (replacement) of a vendor's curses. --disable-overwrite turns this behavior off. ### ncurses-1.9.6 -> 1.9.7 * corrected return values of setupterm() * Fixed some bugs in tput (it does padding now) * fixed a bug in tic that made it do the wrong thing on entries with more than one `use' capability. * corrected the screen-size calculation at startup time to alter the numeric capabilities as per SVr4, not just LINES and COLS. * toe(1) introduced; does what infocmp -T used to. * tic(1) can now translate AIX box1 and font[0123] capabilities. * tic uses much less core, the dotic.sh kluge can go away now. * fix read_entry() and write_entry() to pass through cancelled capabilities OK. * Add $HOME/.terminfo as source/target directory for terminfo entries. * termcap compilation now automatically dumps an entry to $HOME/.terminfo. * added -h option to toe(1). * added -R option to tic(1) and infocmp(1). * added fallback-entry-list feature. * added -i option to infocmp(1). * do a better job at detecting if we're on SCO. ### ncurses-1.9.5 -> 1.9.6 * handling of TERMCAP environment variables now works correctly. * various changes to shorten termcap translations to less that 1024 chars. * tset(1) added * mouse support for xterm. * most data tables are now const and accordingly live in shareable text space. * Obey the XPG4/SVr4 practice that echo() is initally off. * tic is much better at translating XENIX and AIX termcap entries now. * tic can interpret ko capabilities now. * integrated Juergen Pfeifer's forms library. * taught write_entry() how not to write more than it needs to; this change reduces the size of the terminfo tree by a full 26%! * infocmp -T option added. * better warnings about historical tic quirks from tic. ### ncurses 1.9.4 -> 1.9.5 * menus library is now included with documentation. * lib_mvcur has been carefully profiled and tuned. * Fixed a ^Z-handling bug that was tanking lynx(1). * HJ Lu's patches for ELF shared libraries under Linux * terminfo.src 9.8.2 * tweaks for compiling in seperate directories. * Thomas Dickey's patches to support NeXT's brain-dead linker * Eric Raymond's patches to fix problems with long termcap entries. * more support for shared libraries under SunOS and IRIX. ### ncurses 1.9.3 -> 1.9.4 * fixed an undefined-order-of-evaluation bug in lib_acs.c * systematically gave non-API public functions and data an _nc_ prefix. * integrated Juergen Pfeifer's menu code into the distribution. * totally rewrote the knight test game's interface ### ncurses 1.9.2c -> 1.9.3 * fixed the TERMCAP_FILE Support. * fixed off-by-one errors in scrolling code * added tracemunch to the test tools * took steps to cut the running time of make install.data ### ncurses 1.9.2c -> 1.9.2d * revised 'configure' script to produce libraries for normal, debug, profile and shared object models. ### ncurses 1.9.1 -> 1.9.2 * use 'autoconf' to implement 'configure' script. * panels support added * tic now checks for excessively long termcap entries when doing translation * first cut at eliminating namespace pollution. ### ncurses 1.8.9 -> 1.9 * cleanup gcc warnings for the following: use size_t where 'int' is not appropriate, fixed some shadowed variables, change attr_t to compatible with chtype, use attr_t in some places where it was confused with 'int'. * use chtype/attr_t casts as appropriate to ensure portability of masking operations. * added-back waddchnstr() to lib_addstr.c (it had been deleted). * supplied missing prototypes in curses.h * include <termcap.h> in lib_termcap.c to ensure that the prototypes are consistent (they weren't). * corrected prototype of tputs in <termcap.h> * rewrote varargs parsing in lib_tparm.c (to avoid referencing memory that may be out of bounds on the stack) -- Purify found this. * ensure that TRACE is defined in lib_trace.c (to solve prototype warnings from gcc). * corrected scrolling-region size in 'mvcur_wrap()' * more spelling fixes * use 'calloc()' to allocate WINDOW struct in lib_newwin.c (Purify). * set default value for SP->_ofp in lib_set_term.c (otherwise SunOS dumps core in init_acs()). * include <errno.h> in write_entry.c (most "braindead" includes declare errno in that file). ### ncurses 1.8.8 -> 1.8.9 * compile (mostly) clean with gcc 2.5.8 -Wall -Wstrict-prototypes -Wmissing-prototypes -Wconversion and using __attribute__ to flush out non-portable use of "%x" for pointers, or for chtype data (which is declared as a long). * modified doupdate to ensure that typahead was turned on before attempting select-call (otherwise, some implementations hang). * added trace mask TRACE_FIFO, use this in lib_getch.c to allow finer resolution of traces. * improved bounds checking on several critical functions. * the data directory has been replaced by the new master terminfo file. * -F file-comparison option added to infocmp. * compatibility with XSI Curses is now documented in the man bages. * wsyncup/wsyncdown functions are reliable now; subwindow code in general is much less flaky. * capabilities ~msgr, tilde_glitch, insert_padding, generic_type, no_pad_char, memory_above, memory_below, and hard_copy are now used properly. * cursor-movement optimization has been completely rewritten. * vertical-movement optimization now uses hardware scrolling, il, dl. ### ncurses 1.8.7 -> 1.8.8 * untic no longer exists, infocmp replaces it. * tic can understand termcap now, especially if it is called captoinfo. * The Linux Standard Console terminfo entry is called linux insead of console. It also uses the kernel's new method of changing charsets. * initscr() will EXIT upon error (as the docs say) This wil mostly happen if you try to run on an undefined terminal. * I can get things running on AIX but tic can't compile terminfo. I have to compile entries on another machine. Volunteers to hunt this bug are welcome. * wbkgd() and wbkgdset() can be used to set a windows background to color. wclear()/werase() DO NOT use the current attribute to clear the screen. This is the way SVR4 curses works. PDCurses 2.1 is broken in this respect, though PDCurses 2.2 has been fixed. * cleaned up the test/ directory. * test/worm will segfault after quite a while. * many spelling corrections courtesy of Thomas E. 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.
