PDCurses 2.7 - 2005/12/30

Note - new maintainer: William McBrine

NEW FEATURES:

• Functions: delscreen(), getattrs(), has_key(), slk_color(), wcolor_set(), wtimeout().

• Macros: color_set(), mvhline(), mvvline(), mvwgetnstr(), mvwhline(), mvwvline(), timeout(), wresize().

• Stub implementations of terminfo functions (including a term.h).

• More stubs for compatibility: filter(), getwin(), putwin(), noqiflush(), qiflush(), scr_dump(), scr_init(), scr_restore(), scr_set(), use_env(), vidattr(), vidputs().

• The terminal's default colors are used as curses' default colors when the environment variable "PDC_ORIGINAL_COLORS" is set to any value (Win32 only at the moment).

• Simplified build system.

• Replaced PDC_STATIC_BUILD with its opposite, PDC_DLL_BUILD (see .mak files for more info).

• Minimal implementation of color_content() -- no longer a stub.

• Added the remaining ACS defines (ACS_S3, ACS_BBSS, etc.) for DOS/OS2/Win; "enhanced" versions of existing ACS characters used.

• Support for scroll wheels.

• Support for Pacific C.

BUGS FIXED:

• Builds correctly (including demos) on all tested platforms (see below); nearly all compiler warnings have been cleaned up; the ptest demo is built on all platforms; "clean" targets are improved.

• The ability to build ncurses_tests has been restored (see demos dir).

• Line-breakout optimization now defaults to off (equivalent to "typeahead(-1)"), so output is not interrupted by keystrokes (it's supposed to resume on the next refresh(), which wasn't working).

• Implicit wrefresh() in wgetch() was not being invoked in nodelay mode.

• subpad() was erroneously offsetting from the origin coordinates of the parent pad (which are always -1,-1).

• In wborder(), whline(), and wvline(), the current (wattrset) attribute was being used, but not the current background (wbkgd).

• Allow Russian 'r' character ASCII 0xe0 to be returned.

• termattrs() now also returns A_UNDERLINE, A_REVERSE.

• In Win32, with large scrollback buffers set, there was an unwanted "scrollup" effect on startup.

• Revamped keyboard handling for Win32.

• New screen resize method for Win32.

• napms(), delay_output(), etc. now work with Cygwin.

• curs_set(0) wasn't working in Win32 in full-screen (ALT-ENTER) mode -- the cursor stayed on.

• The A_REVERSE attribute was broken in XCurses.

• On 64-bit systems, XCurses was ignoring every other keystroke.

• Added focus hints for XCurses.

• Demos (except for tuidemo) once again have their proper titles in XCurses (using Xinitscr() instead of the obsolete XCursesProgramName).

• The 16-bit chtype is a working option again (by removing #define CHTYPE_LONG from curses.h), except in XCurses. It's not recommended; but if your needs are limited, it still works.

• Reset screen size in resetty() under DOS, as in Win32 and OS/2.

• Changes for cursor size under DOS.

• Automatic setting of BIOS mode for CGA under DOS now works.

• The cursor is now always updated in PDC_gotoxy(); this fixes the problem of missing characters in BIOS mode.

• Macros nocbreak(), cbreak(), nocrmode(), crmode(), nodelay(), nl() and nonl() now return OK.

• ERR and OK are now defined as -1 and 0, respectively, for compatibility with other curses implementations -- note that this change is not binary compatible; you'll have to rebuild programs that use shared/dynamic libraries.

• Added "const" to prototypes where appropriate.

• Miscellaneous code cleanup.

and of course, MARK HESSLING, for his over 13 years of service as the maintainer of PDCurses. Plus, thanks to all who've reported bugs or requested features. Apologies to anyone I've forgotten.

This version was tested on Turbo C++ 3.0 and Borland C++ 3.1 for DOS; DJGPP 2.X; Open Watcom 1.3 for DOS (16 and 32-bit), Windows and OS/2; EMX 0.9d and the "newgcc" version of EMX; Borland C++ 5.5 for Windows; recent versions of MinGW, Cygwin, LCC-Win32 and Microsoft Visual C++; and gcc under several flavors of Linux, Mac OS X, *BSD and Solaris.

PDCurses 2.6 - 2003/01/08

BUGS FIXED:

• Allow accented characters on Win32 platform when run on non-English keyboards.

• Allow "special" characters like Ctrl-S, Ctrl-Q under OS/2 to be returned.

• Some bugs with halfdelay() fixed by William McBrine.

• pechochar() should now work correctly.

• redrawwin() macro in curses.h was incorrect - fixed by Alberto Ornaghi

• Don't include "special" characters like KEY_SHIFT_L to be returned in getnstr() family. Bug 542913

• Entering TAB in wgetnstr() no longer exceeds requested buffer size. Bug 489233

• Fixed bug 550066, scrollok() and pads. Also beep() called when buffer exceeded. Bug 562041.

• Reverse video of X11 selection reinstated. Pablo Garcia Abio??

• Right Alt modifier now works like left Alt modifier under Win32

• Add support for all libXaw replacement libraries with Scrollbar bug. Note that for this to work, you still have to change the libXaw replacement libraries to fix the bug :-(

• Don't trap signals in XCurses if calling application has ignored them. Change by Frank Heckenbach.

• Bug reports from Warren W. Gay: - Fix termattrs() to return A_REVERSE and A_BLINK on all platforms. - Fix definition of getsyx() and setsyx() to be consistent with ncurses. Bug 624424. - Fix definition of echo() and noecho(). Bug 625001. - Fix definition of keypad() and leaveok(). Bug 632653. - Missing panel_hidden() prototype. Bug 649320.

• Fixed bug with calling def_prog_mode(), resize_term(), reset_prog_mode(); the resize details were being lost.

NEW FEATURES:

• Clipboard support now available on DOS platform, but handled internally to the currently running process.

• New X11 resource: textCursor, allows the text cursor to be specified as a vertical bar, or the standard horizontal bar. Thanks to Frank Heckenbach for the suggestion.

NEW COMPILER SUPPORT:

• lcc-win32 now works correctly
