These are the highlights from the - change-log since ncurses 5.4 release. + change-log since ncurses 5.5 release. Interface changes: - * terminfo installs "xterm-new" as "xterm" entry rather than - "xterm-old" (aka xterm-r6). - * terminfo data is installed using the tic -x option (few systems - still use ncurses 4.2). - * modify C++ binding to work with newer C++ compilers by providing - initializers and using modern casts. Old-style header names are - still used in this release to allow compiling with not-so-old - compilers. - * modify parameter type in c++ binding for insch() and mvwinsch() to - be consistent with underlying ncurses library (was char, is - chtype). - * change NCursesWindow::err_handler() to a virtual function. - * form and menu libraries now work with wide-character data. - Applications which bypassed the form library and manipulated the - FIELD.buf data directly will not work properly with libformw, - since that no longer points to an array of char. The - set_field_buffer() and field_buffer() functions translate to/from - the actual field data. - * add symbol to curses.h which can be used to suppress include of - stdbool.h, e.g., - #define NCURSES_ENABLE_STDBOOL_H 0 - #include - - * change SP->_current_attr to a pointer, adjust ifdef's to ensure - that libtinfo.so and libtinfow.so have the same ABI. The reason - for this is that the corresponding data which belongs to the - upper-level ncurses library has a different size in each model. - * winnstr() now returns multibyte character strings for the - wide-character configuration. - * assume_default_colors() no longer requires that - use_default_colors() be called first. - * data_ahead() now works with wide-characters. - * slk_set() and slk_wset() now accept and store multibyte or - multicolumn characters. - * start_color() now returns OK if colors have already been started. - start_color() also returns ERR if it cannot allocate memory. - * pair_content() now returns -1 for consistency with init_pair() if - it corresponds to the default-color. - * unctrl() now returns null if its parameter does not correspond to - an unsigned char. + * generate linkable stubs for some macros: + getbegx, getbegy, getcurx, getcury, getmaxx, getmaxy, getparx, + getpary, getpary, + and (for libncursesw) + wgetbkgrnd New features and improvements: * library - + environment variable NCURSES_NO_UTF8_ACS supports - miscellaneous terminal emulators which ignore alternate - character set escape sequences when in UTF-8 mode. - + modify initialization of key lookup table so that if an - extended capability (tic -x) string is defined, and its name - begins with 'k', ncurses will automatically treat it as a - key. - + change GPM initialization, using dl library to load it - dynamically at runtime. - + form, menu and panel libraries support debug-tracing. - * add NCURSES-Programming-HOWTO.html by Pradeep Padala (see - http://tldp.org/HOWTO/NCURSES-Programming-HOWTO/). + + support hashed databases for the terminal descriptions. This + uses the Berkeley database, has been tested for several + versions on different platforms. + + add use_legacy_coding() function to support lynx's + font-switching feature. + + add extension nofilter(), to cancel a prior filter() call. + + add/install a package config script, e.g., ncurses5-config or + ncursesw5-config, according to configuration options. + + provide ifdef for NCURSES_NOMACROS which suppresses most + macro definitions from curses.h, i.e., where a macro is + defined to override a function to improve performance. + + make ifdef's consistent in curses.h for the extended colors + so the header file can be used for the normal curses library. + The header file installed for extended colors is a variation + of the wide-character configuration. + + improve tgetstr() by making the return value point into the + user's buffer, if provided. + + add ifdef's allowing ncurses to be built with tparm() using + either varargs (the existing status), or using a + fixed-parameter list (to match X/Open). + + widen the test for xterm kmous a little to allow for other + strings than "\E[M", e.g., for xterm-sco functionality in + xterm. + + modify wgetnstr() to return KEY_RESIZE if a sigwinch occurs. + + move prototypes for wide-character trace functions from + curses.tail to curses.wide to avoid accidental reference to + those if _XOPEN_SOURCE_EXTENDED is defined without ensuring + that is included. + + change the way shared libraries (other than libtool) are + installed. Rather than copying the build-tree's libraries, + link the shared objects into the install directory. This + makes the --with-rpath option work except with $(DESTDIR). + + several improvements for rendering in hpterm. These are only + available if the library is configured using + --enable-xmc-glitch. + + Add NCURSES_NO_HARD_TABS and NCURSES_NO_MAGIC_COOKIE + environment variables to allow runtime suppression of the + related hard-tabs and xmc-glitch features. * programs: - * infocmp: - + The -i option now matches 8-bit controls against its table - entries, e.g., so it can analyze the xterm-8bit entry. - + add "-x" option to infocmp like tic's "-x", for use in "-F" - comparisons. This modifies infocmp to only report extended - capabilities if the -x option is given, making this more - consistent with tic. Some scripts may break, since infocmp - previous gave this information without an option. - * tic: - + modify termcap-parsing to retain 2-character aliases at the - beginning of an entry if the "-x" option is used in tic. - + filter out long extended names when translating to termcap - format. Only two characters are permissible for termcap - capability names. - + correct translation of "%%" in terminfo format to termcap, - e.g., using "tic -C". - + modify the "-c -v" options to ignore delays when comparing - strings. Also modify it to ignore a canceled sgr string, - e.g., for terminals which cannot properly combine attributes - in one control sequence. - + add a check for improperly ended strings, i.e., where a - following line begins in column 1. - + add a check in tic for terminfo entries having an sgr0 but no - sgr string. This confuses Tru64 and HPUX curses when combined - with color, e.g., making them leave line-drawing characters - in odd places. - + add check (with debug configuration) that provides about the - runtime changes that would be made to sgr0 for termcap - applications. - * tset: - + add -c and -w options to allow user to suppress ncurses' - resizing of the terminal emulator window in the special case - where it is not able to detect the true size. + + add new test programs: chgat.c, demo_altkeys.c, echochar.c, + foldkeys.c, movewindow.c, redraw.c, (noting that existing + test programs also were modified to test additional + features). + + modify tack to test extended capability function-key strings. + + modify toe to access termcap data, e.g., via cgetent() + functions, or as a text file if those are not available. + + improve infocmp/tic -f option formatting. + + add toe -a option, to show all databases. This uses new + private interfaces in the ncurses library for iterating + through the list of databases. + + modify MKfallback.sh to use tic -x when constructing fallback + tables to allow extended capabilities to be retrieved from a + fallback entry. + * terminal database + + add terminfo entries for xfce terminal (xfce) and multi gnome + terminal (mgt) + + add nsterm-16color entry + + updated mlterm terminfo entry + + add kon, kon2 and jfbterm terminfo entry + + remove invis capability from klone+sgr, mainly used by linux + entry, since it does not really do this + + add ka2, kb1, kb3, kc2 to vt220-keypad as an extension + + add shifted up/down arrow codes to xterm-new as kind/kri + strings + + add hpterm-color terminfo entry + + add 256color variants of terminfo entries for programs which + are reported to implement this feature + + correct order of use-clauses in rxvt-basic entry which made + codes for f1-f4 vt100-style rather than vt220-style. Major bug fixes: - * improve logic in tgetent() which adjusts the termcap "me" string - to work with ISO-2022 string used in xterm-new. This is a feature - that was incompletely implemented in ncurses 5.3. ncurses attempts - to provide termcap clients with the portion of the sgr0 (termcap - "me") string that does not reset line-drawing. - * cells in the WINDOW which are continuations of a multicolumn - character are encoded differently, making repainting more - reliable. - * amend change to setupterm() in ncurses 5.4 (20030405) which would - reuse the value of cur_term if the same output was selected. This - now reuses it only when setupterm() is called from tgetent(), - which has no notion of separate SCREENs. Note that tgetent() must - be called after initscr() or newterm() to use this feature. - * make setcchar() now works when its wchar_t* parameter is pointing - to a string which contains more data than can be converted. - * win_wchnstr() now works for more than one cell. - * resizeterm() now processes all levels of window hierarchy. - * disable GPM mouse support when $TERM happens to be prefixed with - "xterm". Gpm_Open() would otherwise assert that it can deal with - mouse events in this case. - * add SP->_screen_acs_map[], used to ensure that mapping of missing - line-drawing characters is handled properly. For example, - ACS_DARROW is absent from xterm-new, and it was coincidentally - displayed the same as ACS_BTEE. + * correct a typo in configure --with-bool option for the case where + --without-cxx is used. + * move assignment from environment variable ESCDELAY from initscr() + down to newterm() so the environment variable affects timeouts for + terminals opened with newterm() as well. + * modify werase to clear multicolumn characters that extend into a + derived window. + * modify wchgat() to mark updated cells as changed so a refresh will + repaint those cells. + * correct logic in wadd_wch() and wecho_wch(), which did not guard + against passing the multi-column attribute into a call on + waddch(), e.g., using data returned by win_wch() + * fix redrawing of windows other than stdscr using wredrawln() by + touching the corresponding rows in curscr. + * reduce memory leaks in repeated calls to tgetent() by remembering + the last TERMINAL* value allocated to hold the corresponding data + and freeing that if the tgetent() result buffer is the same as the + previous call. + * modify read_termtype() so the term_names data is always allocated + as part of the str_table, a better fix for a memory leak. + * fix wins_nwstr(), which did not handle single-column non-8bit + codes. + * modify wbkgrnd() to avoid clearing the A_CHARTEXT attribute bits + since those record the state of multicolumn characters. + * improve SIGWINCH handling by postponing its effect during + newterm(), etc., when allocating screens. + * remove 970913 feature for copying subwindows as they are moved in + mvwin(). + * add checks in waddchnstr() and wadd_wchnstr() to stop copying when + a null character is found. + * add some checks to ensure current position is within scrolling + region before scrolling on a new line. + * add a workaround to ACS mapping to allow applications such as + test/blue.c to use the "PC ROM" characters by masking them with + A_ALTCHARSET. This worked up til 5.5, but was lost in the revision + of legacy coding. Portability: * configure script: + new options: - --enable-largefile - set compiler and linker flags to use largefile - support. - - --enable-ext-colors - Allow encoding of 256 foreground and background - colors, e.g., with the xterm-256color or - xterm-88color terminfo entries. This requires ABI 6 - because it changes the size of cchar_t. - - --enable-ext-mouse - This defines NCURSES_MOUSE_VERSION 2, and modifies - the encoding of mouse events to support wheel mice, - which may transmit buttons 4 and 5. This works with - xterm and similar terminal emulators. This requires - ABI 6 because it changes the encoding of mouse - events. - - --with-chtype - overriding of the non-LP64 model's use of chtype - - --with-mmask-t - overriding of the non-LP64 model's use of mmask_t - - --without-xterm-new - Installs "xterm-old" as the "xterm" entry of the - terminfo database. - - + The --with-termlib option now accepts a value which sets the - name of the terminfo library. This would allow a packager to - build libtinfow.so renamed to coincide with libtinfo.so - + fixes/improvements for cross-compiling: - o suppress $suffix in misc/run_tic.sh when - cross-compiling. This allows cross-compiles to use the - host's tic program to handle the "make install.data" - step. - o correct BUILD_CPPFLAGS substitution in - ncurses/Makefile.in, to allow cross-compiling from a - separate directory tree. + --with-hashed-db + Use Berkeley hashed database for storing terminfo + data rather than storing each compiled entry in a + separate binary file within a directory tree. + + --without-dlsym + Do not use dlsym() to load GPM dynamically. + + --with-valgrind + Simplify building for testing with valgrind. + + --enable-wgetch-events + Compile with experimental wgetch-events code. + + --enable-signed-char + Store booleans in "signed char" rather than "char". + + + improved options: + + --disable-largefile + make the option work both ways. + + --with-gpm + The option now accepts a parameter, i.e., the name + of the dynamic GPM library to load via dlopen() + + --disable-symlinks + The option now allows one to disable symlink() in + tic even when link() does not work. + + * other configure/build issues: + + remove special case for Darwin in CF_XOPEN_SOURCE configure + macro. + + add configure check to ensure that SIGWINCH is defined on + platforms such as OS X which exclude that when _XOPEN_SOURCE, + etc., are defined + + use ld's -search_paths_first option on Darwin to work around + odd search rules on that platform. + + improve ifdef's for _POSIX_VDISABLE in tset to work with Mac + OS X. + + modify configure script to ensure that if the C compiler is + used rather than the loader in making shared libraries, the + $(CFLAGS) variable is also used. + + use ${CC} rather than ${LD} in shared library rules for + IRIX64, Solaris to help ensure that initialization sections + are provided for extra linkage requirements, e.g., of C++ + applications. + + improve some shared-library configure scripting for Linux, + FreeBSD and NetBSD to make --with-shlib-version work. + + split up dependency of names.c and codes.c in + ncurses/Makefile to work with parallel make. + + modify MKlib_gen.sh to change preprocessor-expanded _Bool + back to bool. + + modify progs/Makefile.in to make tput init work properly with + cygwin, i.e., do not pass a .exe in the reference string used + in check_aliases. * library: - + add ifdef's for _LP64 in curses.h to avoid using wasteful - 64-bits for chtype and mmask_t, but add configure option - --disable-lp64 in case anyone used that configuration. - + modify C++ binding to use some C internal functions to make - it compile properly on Solaris (and other platforms). - + remove check in newwin() that prevents allocating windows - that extend beyond the screen (Solaris does this). - + check for nl_langinfo(CODESET), use it if available.
