PDCurses_2_8

As with the previous version, you should assume that apps linked against older dynamic versions of the library won't work with this one until recompiled.

New features:

  • Simpler, faster.

  • Declarations for all supported, standard functions, per the X/Open Curses 4.2 spec, with the notable exception of getch() and ungetch(). You can disable the use of the macro versions by defining NOMACROS before including curses.h (see xmas.c for an example). NOMACROS yields smaller but theoretically slower executables.

  • New functions: vwprintw(), vwscanw(), vw_printw() and vw_scanw(). This completes the list of X/Open 4.2 functions, except for those concerned with attr_t and wide characters. Some (especially the terminfo/termcap functions) aren't yet fully fleshed out, though.

  • Non-macro implementations for COLOR_PAIR(), PAIR_NUMBER(), getbkgd(), mvgetnstr(), mvwgetnstr(), mvhline(), mvvline(), mvwhline(), and mvwvline(). (The macros are still available, too.)

  • newterm() works now, in a limited way -- the parameters are ignored, and only the first invocation will work (i.e., only one SCREEN can be used).

  • start_color() works now -- which is to say, if you don't call it, you'll only get monochrome output. Also, without calling it, the terminal's default colors will be used, where supported (currently only in Win32). This is equivalent to the PDC_ORIGINAL_COLORS behavior introduced in 2.7, except that only the default colors will be used. (PDC_ORIGINAL_COLORS is still available, if you want to combine the use of specific colors and the default colors.)

  • New logic for termname() and longname(): termname() always returns "pdcurses"; longname() returns "PDCurses for [platform] [adapter] [COLOR/MONO]-YxX" (adapter is only defined for DOS and OS/2). This is the first time these functions return anything in Win32.

  • New installation method for XCurses: the header files are placed in a subdirectory "xcurses" within the include directory, rather than being renamed. (But the renamed xcurses.h and xpanel.h are also installed, for backwards compatibility.) curspriv.h and term.h are now available, and existing curses-based code need no longer be edited to use XCurses' curses.h. And with no more need for explicit XCursesExit() calls (see below), your code need not be changed at all to move from another curses implementation to XCurses. It can be as simple as "gcc -I/usr/local/include/xcurses -lXCurses -oprogname progname.c".

  • Combined readme.* into this HISTORY file, and incorporated the old 1.x (PCcurses) history.

  • New functionality for the testcurs demo: ACS character display; menu support for PgUp, PgDn, Home and End; centered menu; and it can now be resized in X.

  • Added modified versions of the rain and worm demos from ncurses.

Bug fixes and such:

  • Big cleanup of dead and redundant code, including unneeded defines, ifdefs, and structure elements.

  • flushinp() was not implemented for Win32.

  • resetty() was not restoring LINES and COLS.

  • nonl() made '\n' print a line feed without carriage return. This was incorrect.

  • Removed bogus implementation of intrflush().

  • The line-breakout optimization system, disabled by default in 2.7, is removed in 2.8. It simply didn't work, and never has. (The typeahead() function remains, for compatibility, but does nothing.)

  • The declarations for the printw() and scanw() function families were erroneously ifdef'd.

  • Safer printw() calls on platforms that support vsnprintf().

  • Use the native vsscanf() in DJGPP, MinGW and Cygwin.

  • ACS_BLOCK now works in X.

  • Explicit calls to XCursesExit() are no longer needed.

  • XCURSES is now defined automatically if not DOS, OS2 or WIN32.

  • The default icon for XCurses wasn't working (had to remove the focus hint code to fix this). Also, the default title is now "XCurses" instead of "main".

  • Incorrect dimensions (undercounting by two in each direction) were shown while resizing in X.

  • Scroll wheel events were not always correctly reported in X.

  • 32 bits are enough for the "long" chtype, but 64 bits were used on a 64-bit system, wasting memory. Now conditioned on _LP64. This could be faster, too.

  • The short, 16-bit chtype now works with XCurses.

  • Corrected return value for is_linetouched(), is_wintouched(), can_change_color() and isendwin() (bool instead of int).

  • timeout(), wtimeout(), idcok() and immedok() return void.

  • pair_content() takes a short.

  • Replaced incorrect usages of attr_t with chtype. attr_t is still typedef'd, for backwards compatibility. (It's supposed to be used for the WA_*-style functions, which PDCurses doesn't yet support.)

  • Added const where required by the spec, and in other appropriate places.

  • Removed PDC_usleep(). napms() is now the core delay routine.

  • Fixed poll() support in napms().

  • Various changes to the internal PDC_* functions -- don't depend on these, and don't use them unless you absolutely have to.

  • Some routines accessed window structures in their variable declarations, before checking for a NULL window pointer.

  • Dropped support for the undocumented PDC_FULL_DISPLAY, wtitle(), and PDC_print().

  • Cleaned up remaining warnings.

  • Reduced unnecessary #include directives -- speeds up compilation.

  • Fix for demos build in Borland/DOS -- the makefile in 2.7 didn't specify the memory model. Reported by Erwin Waterlander.

  • Simplified the makefiles; e.g., some now build each demo in a single step, and Watcom no longer uses demos.lnk. Also, the demo exes are now stripped when possible; maximum compression used for archives built by the makefiles; xcurses-config removed as part of "make distclean"; and I tweaked optimization for some platforms.

  • Reverted to /usr/local/ as default installation directory for XCurses.

  • Upgraded to autoconf 2.59... instantly doubling the size of the configure script. Ah well. Otherwise, simplified the build system.

  • Dropped support for pre-ANSI compilers. (It hasn't worked since at least version 2.4, anyway.)

  • Revised and, I hope, clarified the boilerplate and other comments.

  • Simplified logging and RCS ids; added RCS ids where missing.

  • Consistent formatting for all code, approximately equivalent to "indent -kr -i8 -bl -bli0", with adjustments for 80 columns.
