PDCurses 3.4 - 2008/09/08

=========================

Nothing much new this time, but I've been sitting on some bug fixes for

almost a year, so it's overdue. Apart from bugs, the main changes are in

the documentation.

New features:

- setsyx() is now a function rather than a macro.

Bug fixes and such:

- In x11, the xc_atrtab table size was under-calculated by half,

  resulting in crashes at (oddly) certain line counts. (It should've

  crashed a lot more.) Reported by Mark Hessling.

- Test for moved cursor was omitting the window origin offset. Reported

  by Carey Evans.

- Is DOS and OS/2, the value for max items in key_table was still wrong.

  Reported by C.E.

- Changed isendwin() so it won't crash after delscreen().

- Ensure zero-termination in PDC_mbstowcs() and PDC_wcstombs().

- Disable QuickEdit Mode when enabling mouse input for the Win32

  console; reported by "Zalapkrakna".

- Fix for building under Innotek C (I hope). Report by Elbert Pol, fix

  courtesy of Paul Smedley.

- Unified exports list with no duplicates -- pdcurses.def is now built

  from components at compile time.

- Don't install curspriv.h, and don't include it with binary

  distributions.

- Building DLLs with LCC is no longer supported, due to the primitive

  nature of its make.exe.

- Export the terminfo stub functions from the DLLs, too.

- Added support for Apple's ".dylib" in configure. Suggested by Marc

  Vaillant (who says it's needed with OS 10.5.)

- In sdl1/Makefile.mng, ensure that CC is set.

- In the gcc makefiles, "$?" didn't really have the desired effect --

  _all_ the dependencies showed up on the command line, including

  curses.h, and pdcurses.a twice.  And apparently, this can mess up some

  old version (?) of MinGW. So, revert to spelling out "tuidemo.o

  tui.o". Reported by "Howard L."

- Extensive documentation revision and reorganizing. More to do here.

  For example, I moved the build instructions from INSTALL (which never

  really described installation) to the platform-specific READMEs.

- New indentation standard: four spaces, no tabs.

------------------------------------------------------------------------

PDCurses 3.3 - 2007/07/11

=========================

This release adds an SDL backend, refines the demos, and is faster in

some cases.

New features:

- SDL port. See INSTALL, doc/sdl.txt and sdl1/* for details.

- Double-buffering -- minimize screen writes by checking, in doupdate()

  and wnoutrefresh(), whether the changes to curscr are really changes.

  In most cases, this makes no difference (writes were already limited

  to areas marked as changed), but it can greatly reduce the overhead

  from touchwin(). It also helps if you have small, separated updates on

  the same line.

- The PDC_RGB colors can now be used, or not, with any platform (as long

  as the same options are used when compiling both the library and

  apps). This may help if you have apps that are hardwired to assume

  certain definitions.

- Restored the use_default_colors() stuff from the ncurses versions of

  the rain and worm demos, to make them "transparent" (this is useful

  now, with the SDL port); added transparency to newdemo.

- Added setlocale() to tuidemo, to make it easier to browse files with

  non-ASCII characters.

- Sped up firework demo by replacing unneeded clear() and init_pair()

  calls.

- Allow exit from ptest demo by typing 'q'.

- New functions for implementors: PDC_pair_content() and PDC_init_pair()

  (the old pdc_atrtab stuff was arguably the last remnant of code in the

  pdcurses directory that was based on platform details).

Bug fixes and such:

- Implicit wrefresh() needs to be called from wgetch() when the window's

  cursor position is changed, even if there are no other changes.

- Set SP->audible on a per-platform basis, as was documented in

  IMPLEMNT, but not actually being done.

- Minor tweaks for efficiency and readability, notably with wscrl().

- tuidemo didn't work correctly on monochrome screens when A_COLOR was

  defined -- the color pair numbers appeared as the corresponding

  character; also, the input box was (I now realize) broken with ncurses

  since our 2.7, and broke more subtly with PDCurses' new implicit

  refresh handling; also, the path to the default file for the Browse

  function was a bit off.

- Assume in the demos that curs_set() is always available -- there's no

  good test for this, and the existing tests were bogus.

- Made the command-line parameter for ptest work. (If given an argument,

  it delays that number of milliseconds between changes, instead of

  waiting for a key, and automatically loops five times.)

- Building the Win32 DLL with MinGW or Cygwin wouldn't work from outside

  the platform directory.

- Building the X11 port with Cygwin required manually editing the

  Makefile after configuring; no longer. Reported by Warren W. Gay.

- Minor tightening of configure and makefiles.

- Bogus references to "ACS_BLCORNER" in the border man page. Reported by

  "Walrii".

- slk_wlabel() was not documented.

- Spelling cleanup.

- Changed RCSIDs to not end with a semicolon -- avoids warnings when

  compiling with the -pedantic option.

- Merged latin-1.txt into x11.txt.

- Updated config.guess and config.sub to more recent versions.

------------------------------------------------------------------------

PDCurses 3.2 - 2007/06/06

=========================

This release mainly covers changes to the build process, along with a

few structural changes.

New features:

- The panel library has been folded into the main library. What this

  means is that you no longer need to specify "-lpanel" or equivalent

  when linking programs that use panel functionality with PDCurses;

  however, panel.lib/.a is still provided (as a copy of pdcurses.lib/.a)

  so that you can, optionally, build your projects with no changes. It

  also means that panel functionality is available with the DLL or

  shared library. Note that panel.h remains separate from curses.h.

- Setting the PDCURSES_SRCDIR environment variable is no longer required

  before building, unless you want to build in a location other than the

  platform directory. (See INSTALL.)

- MinGW and Cygwin makefiles support building DLLs, via the "DLL=Y"

  option. Partly due to Timofei Shatrov.

- Support for the Digital Mars compiler.

- Watcom makefiles now use the "loaddll" feature.

Bug fixes and such:

- Eliminated the platform defines (DOS, WIN32, OS2, XCURSES) from

  curses.h, except for X11-specific SCREEN elements and functions.

  Dynamically-linked X11 apps built against an old version will have

  their red and blue swapped until rebuilt. (You can define PDC_RGB to

  build the library with the old color scheme, but it would also have to

  be defined when building any new app.) Any app that depends on

  PDCurses to determine the platform it's building on will have to make

  other arrangements.

- Documentation cleanup -- added more details; removed some content that

  didn't apply to PDCurses; moved the doc-building tool to the doc

  directory; changed *.man to *.txt.

- The EMX makefile now accepts "DLL=Y", builds pdcurses.dll instead of

  curses.dll, builds either the static library or the DLL (not both at

  once), and links all the demos with the DLL when building it.

- In Win32, read the registry only when needed: when init_color() or

  color_content() is called, instead of at startup.

- A few additional consts in declarations.

- The Win32 compilers that build DLLs now use common .def files.

- panel.h functions sorted by name, as with other .h files; curses.h is

  no longer included by repeated inclusions of panel.h or term.h.

- Simplified Borland makefiles.

- Makefile.aix.in depended on a file, xcurses.exp, that was never there.

  This problem was fixed as part of the change to common .def files;

  however, I still haven't been able to test building on AIX.

------------------------------------------------------------------------

PDCurses 3.1 - 2007/05/03

=========================

Primarily clipboard-related fixes, and special UTF-8 support.

New features:

- "Force UTF-8" mode, a compile-time option to force the use of UTF-8

  for multibyte strings, instead of the system locale. (Mainly for

  Windows, where UTF-8 doesn't work well in the console.) See INSTALL.

- Multibyte string support in PDC_*clipboard() functions, and in Win32's

  PDC_set_title().

- Added the global string "ttytype", per other curses implementations,

  for compatibility with old BSD curses.

- Real functions for the "quasi-standard aliases" -- crmode(),

  nocrmode(), draino(), resetterm(), fixterm() and saveterm().

  (Corresponding macros removed.)

Bug fixes and such:

- In Win32, under NT-family OSes, the scrollback buffer would be

  restored by endwin(), but would not be turned off again when resuming

  curses after an endwin(). The result was an odd, partly-scrolled-up

  display. Now, the buffer is toggled by PDC_reset_prog_mode() and

  PDC_reset_shell_mode(), so it's properly turned off when returning

  from an endwin().

- In 3.0, selection in X11 didn't work. (Well, the selecting worked, but

  the pasting elsewhere didn't.) This was due to the attempted fix

  "don't return selection start as a press event," so that's been

  reverted for now.

- PDC_setclipboard() was locking up in X11. Reported by Mark Hessling.

- Missing underscore in the declaration of XC_say() prevented

  compilation with PDCDEBUG defined.  Reported by M.H.

- Off-by-one error in copywin() -- the maximum coordinates for the

  destination window should be inclusive. Reported by Tiago Dionizio.

- Start in echo mode, per X/Open. Reported by T.D.

- Strip leading and trailing spaces from slk labels, per a literal

  reading of X/Open. Suggested by Alexey Miheev (about ncurses, but it

  also applies here).

- The #endif for __PDCURSES__ needs to come _after_ the closing of the

  extern "C". This has been broken since June 2005. Fortunately (?), it

  only shows up if the file is included multiple times, and then only in

  C++. Reported on the DOSBox forums.

- Use CF_OEMTEXT instead of CF_TEXT in the narrow versions of the

  clipboard functions in Win32, to match the console.

- Changed the format of the string returned from longname().

- In the clipboard test in the testcurs demo, use a single mvprintw() to

  display the return from PDC_getclipboard(), instead of a loop of

  addch(), which was incompatible with multibyte strings.

- Moved has_key() into the keyname module, and documented it.

- Moved RIPPEDOFFLINE to curspriv.h.

- Typos in IMPLEMNT.

------------------------------------------------------------------------

PDCurses 3.0 - 2007/04/01

=========================

The focuses for this release are X/Open conformance, i18n, better color

support, cleaner code, and more consistency across platforms.

This is only a brief summary of the changes. For more details, consult

the CVS log.

New features:

- An almost complete implementation of X/Open curses, including the

  wide-character and attr_t functions (but excluding terminfo). The

  wide-character functions work only in Win32 and X11, for now, and

  require building the library with the appropriate options (see

  INSTALL). Note that this is a simplistic implementation, with exactly

  one wchar_t per cchar_t; the only characters it handles properly are

  those that are one column wide.

- Support for X Input Methods in the X11 port (see INSTALL). When built

  this way, the internal compose key support is disabled in favor of

  XIM's, which is a lot more complete, although you lose the box cursor.

- Multibyte character support in the non-wide string handling functions,

  per X/Open. This only works when the library is built with wide-

  character support enabled.

- Mouse support for DOS and OS/2. The DOS version includes untested

  support for scroll wheels, via the "CuteMouse" driver.

- An ncurses-compatible mouse interface, which can work in parallel with

  the traditional PDCurses mouse interface. See the man page (or

  mouse.c) for details.

- DOS and OS/2 can now return modifiers as keys, as in Win32 and X11.

- COLORS, which had been fixed at 8, is now either 8 or 16, depending on

  the terminal -- usually 16. When it's 8, blinking mode is enabled

  (controlled as before by the A_BLINK attribute); when it's 16, bright

  background colors are used instead. On platforms where it can be

  changed, the mode is toggled by the new function PDC_set_blink().

  PDCurses tries to set PDC_set_blink(FALSE) at startup. (In Win32, it's

  always set to FALSE; in DOS, with other than an EGA or VGA card, it

  can't be.) Also, COLORS is now set to 0 until start_color() is called.

- Corresponding to the change in COLORS, COLOR_PAIRS is now 256.

- Working init_color() and color_content(). The OS/2 version of

  init_color() works only in a full-screen session; the Win32 version

  works only in windowed mode, and only in NT-family OSes; the DOS

  version works only with VGA adapters (real or simulated). The Win32

  version is based mostly on James Brown's setconsoleinfo.c

  (www.catch22.net).

- use_default_colors(), assume_default_colors(), and curses_version(),

  after ncurses.

- Added global int TABSIZE, after ncurses and Solaris curses; removed

  window-specific _tabsize.

- Logical extension to the wide-character slk_ funcs: slk_wlabel(), for

  retrieving the label as a wide-character string.

- A non-macro implementation of ncurses' wresize().

- Working putwin(), getwin(), scr_dump() and scr_restore().

- A working acs_map[]. Characters from the ACS are now stored in window

  structures as a regular character plus the A_ALTCHARSET attribute, and

  rendered to the ACS only when displayed. (This allows, for example,

  the correct display on one platform of windows saved from another.)

- In X11, allow selection and paste of UTF8_STRING.

- The testcurs demo now includes a color chart and init_color() test, a

  wide character input test, a display of wide ACS characters with

  sample Unicode text, a specific test of flash(), more info in the

  resize test, and attempts to change the width as well as the height.

- Command-line option for MSVC to build DLLs (see INSTALL). Also, the

  naming distinction for DLLs ("curses" vs. "pdcurses") is abandoned,

  and either the static lib or DLL is built, not both at once (except

  for X11).

- For backwards compatibility, a special module just for deprecated

  functions -- currently PDC_check_bios_key(), PDC_get_bios_key(),

  PDC_get_ctrl_break() and PDC_set_ctrl_break(). These shouldn't be used

  in applications, but currently are... in fact, all the "private"

  functions (in curspriv.h) are subject to change and should be avoided.

- A new document, IMPLEMNT, describing PDCurses' internal functions for

  those wishing to port it to new platforms.

- Mark Hessling has released the X11 port to the public domain.

  (However, x11/ScrollBox* retain their separate copyright and MIT-like

  license.)

Bug fixes and such:

- Most of the macros have been removed (along with the NOMACROS ifdef).

  The only remaining ones are those which have to be macros to work, and

  those that are required by X/Open to be macros. There were numerous

  problems with the macros, and no apparent reason to keep them, except

  tradition -- although it was PCcurses 1.x that first omitted them.

- Clean separation of platform-specific code from the rest. Outside of

  the platform directories, there remain only a few ifdefs in curses.h

  and curspriv.h.

- General reorganization and simplification.

- Documentation revisions.

- When expanding control characters in addch() or insch(), retain the

  attributes from the chtype.

- Preserve the A_ALTCHARSET attribute in addch() and insch().

- Per X/Open, beep() should always return OK.

- On platforms with a controlling terminal (i.e., not X11), curs_set(1)

  now sets the cursor to the shape it had at the time of initscr(),

  rather than always making it small. (Exception for DOS: If the video

  mode has been changed by PDC_resize_screen(), curs_set(1) reverts to

  line 6/7.) The shape is taken from SP->orig_cursor (the meaning of

  which is platform-specific).

- Stop updating the cursor position when the cursor is invisible (this

  gives a huge performance boost in Win 9x); update the cursor position

  from curs_set() if changing from invisible to visible.

- Some tweaking of the behavior of def_prog_mode(), def_shell_mode(),

  savetty(), reset_prog_mode(), reset_shell_mode() and resetty()...

  still not quite right.

- flash() was not implemented for Win32 or X. A portable implementation

  is now used for all platforms. Note that it's much slower than the

  old (DOS and OS/2) version, but this is only apparent on an extremely

  slow machine, such as an XT.

- In getstr(), backspacing on high-bit characters caused a double

  backspace.

- hline() and vline() used an incorrect (off by one) interpretation of

  _maxx and _maxy. If values of n greater than the max were specified,

  these functions could access unallocated memory.

- innstr() is supposed to return the number of characters read, not just

  OK or ERR. Reported by Mike Aubury.

- A proper implementation of insch() -- the PDC_chadd()-based version

  wasn't handling the control characters correctly.

- Return ASCII and control key names from keyname() (problem revealed by

  ncurses' movewindow test); also, per X/Open, return "UNKNOWN KEY" when

  appropriate, rather than "NO KEY NAME".

- Turn off the cursor from leaveok(TRUE), even in X11; leaveok(FALSE)

  now calls curs_set(1), regardless of the previous state of the cursor.

- In the slk area, BUTTON_CLICKED events now translate to function keys,

  along with the previously recognized BUTTON_PRESSED events. Of course,

  it should really be checking the events specified by map_button(),

  which still doesn't work.

- napms(0) now returns immediately.

- A unified napms() implementation for DOS -- no longer throttles the

  CPU when built with any compiler.

- Allow backspace editing of the nocbreak() buffer.

- pair_content(0, ...) is valid.

- There was no check to ensure that the pnoutrefresh() window fit within

  the screen. It now returns an ERR if it doesn't.

- In X11, resize_term() must be called with parameters (0, 0), and only

  when SP->resized is set, else it returns ERR.

- Copy _bkgd in resize_window(). Patch found on Frederic L. W. Meunier's

  web site.

- slk_clear() now removes the buttons completely, as in ncurses.

- Use the current foreground color for the line attributes (underline,

  left, right), unless PDC_set_line_color() is explicitly called. After

  setting the line color, you can reset it to this mode via

  "PDC_set_line_color(-1)".

- Removed non-macro implementations of COLOR_PAIR() and PAIR_NUMBER().

- Dispensed with PDC_chadd() and PDC_chins() -- waddch() and winsch()

  are now (again) the core functions.

- Dropped or made static many obsolete, unused, and/or broken functions,

  including PDC_chg_attrs(), PDC_cursor_on() and _off(),

  PDC_fix_cursor(), PDC_get_attribute(), PDC_get_cur_col() and _row(),

  PDC_set_80x25(), PDC_set_cursor_mode(), PDC_set_rows(),

  PDC_wunderline(), PDC_wleftline(), PDC_wrightline(),

  XCursesModifierPress() and XCurses_refresh_scrollbar().

- Obsolete/unused defines: _BCHAR, _GOCHAR, _STOPCHAR, _PRINTCHAR

  _ENDLINE, _FULLWIN and _SCROLLWIN.

- Obsolete/unused elements of the WINDOW struct: _pmax*, _lastp*,

  _lasts*.

- Obsolete/unused elements of the SCREEN struct: orgcbr, visible_cursor,

  sizeable, shell, blank, cursor, orig_emulation, font, orig_font,

  tahead, adapter, scrnmode, kbdinfo, direct_video, video_page,

  video_seg, video_ofs, bogus_adapter. (Some of these persist outside

  the SCREEN struct, in the platform directories.) Added mouse_wait and

  key_code.

- Removed all the EMALLOC stuff. Straight malloc calls were used

  elsewhere; it was undocumented outside of comments in curspriv.h; and

  there are better ways to use a substitute malloc().

- Single mouse clicks are now reportable on all platforms (not just

  double-clicks). And in general, mouse event reporting is more

  consistent across platforms.

- The mouse cursor no longer appears in full-screen mode in Win32 unless

  a nonzero mouse event mask is used.

- ALT-keypad input now works in Win32.

- In Win32, SetConsoleMode(ENABLE_WINDOW_INPUT) is not useful, and

  appears to be the source of a four-year-old bug report (hanging in

  THE) by Phil Smith.

- Removed the PDC_THREAD_BUILD stuff, which has never worked. For the

  record: PDCurses is not thread-safe. Neither is ncurses; and the

  X/Open curses spec explicitly makes it a non-requirement.

- With the internal compose key system in the X11 port, modifier keys

  were breaking out of the compose state, making it impossible to type

  accented capitals, etc. Also, Multi_key is now the default compose

  key, instead of leaving it undefined by default; and a few more combos

  are supported.

- In X11, the first reported mouse event after startup always read as a

  double-click at position 0, 0. (This bug was introduced in 2.8.)

- In X11, don't return selection start as a press event. (Shift-click on

  button 1 is still returned.)

- In X11, properly handle pasting of high-bit chars. (It was doing an

  unwanted sign extension.)

- In X11, BUTTON_MOVED was never returned, although PDC_MOUSE_MOVED was

  set.

- The fix in 2.8 for the scroll wheel in X11 wasn't very good -- it did

  report the events as scroll wheel events, but it doubled them. Here's

  a proper fix.

- Changed mouse handling in X11: Simpler translation table, with

  XCursesPasteSelection() called from XCursesButton() instead of the

  translation table; require shift with button 1 or 2 for select or

  paste when mouse events are being reported (as with ncurses), allowing

  passthrough of simple button 2 events. This fixes the previously

  unreliable button 2 behavior.

- Modifier keys are now returned on key up in X11, as in Win32. And in

  general, modifier key reporting is more consistent across platforms.

- Modifiers are not returned as keys when a mouse click has occurred

  since the key press.

- In BIOS mode (in DOS), count successive identical output bytes, and

  make only one BIOS call for all of them. This dramatically improves

  performance.

- The cursor position was not always updated correctly in BIOS mode.

- In testcurs, the way the ACS test was written, it would really only

  work with a) PDCurses (with any compiler), or b) gcc (with any

  curses). Here's a more portable implementation.

- Better reporting of mouse events in testcurs.

- Blank out buffer and num before the scanw() test in testcurs, in case

  the user just hits enter or etc.; clear the screen after resizing.

- Allow tuidemo to use the last line.

- Separate left/right modifier keys are now reported properly in Win32.

  (Everything was being reported as _R.)

- Attempts to redirect input in Win32 now cause program exit and an

  error message, instead of hanging.

- Dropped support for the Microway NDP compiler.

- Some modules renamed, rearranged.

- Fixes for errors and warnings when building with Visual C++ 2005.

- In MSVC, the panel library didn't work with the DLL.

- Complete export lists for DLLs.

- Simplified makefiles; moved common elements to .mif files; better

  optimization; strip demos when possible.

- Changed makefile targets of "pdcurses.a/lib" and "panel.a/lib" to

  $(LIBCURSES) and $(LIBPANEL). Suggestion of Doug Kaufman.

- Changed "install" target in the makefile to a double-colon rule, to

  get around a conflict with INSTALL on non-case-sensitive filesystems,

  such as Mac OS X's HFS+. Reported by Douglas Godfrey et al.

- Make PDCurses.man dependent on manext. Suggestion of Tiziano Mueller.

- Set up configure.ac so autoheader works; removed some obsolescent

  macros. Partly the suggestion of T.M.

- The X11 port now builds in the x11 directory (including the demos), as

  with other ports.

- The X11 port should now build on more 64-bit systems. Partly due to

  M.H.

- The default window title and icons for the X11 port are now "PDCurses"

  instead of "XCurses".

- Internal functions and variables made static where possible.

- Adopted a somewhat more consistent naming style: Internal functions

  with external linkage, and only those, have the prefix "PDC_";

  external variables that aren't part of the API use "pdc_"; static

  functions use "_"; and "XC_" and "xc_" prefixes are used for functions

  and variables, respectively, that are shared between both processes in

  the X11 port. Also eliminated camel casing, where possible.

- Changed the encoding for non-ASCII characters in comments and

  documentation from Latin-1 to UTF-8.

------------------------------------------------------------------------

PDCurses 2.8 - 2006/04/01

=========================

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.

PDCurses 2.7 - 2005/12/30

=========================

INTRODUCTION:

 Hello all. As of a few weeks ago, I'm the new maintainer for PDCurses.

 Here's a brief summary of changes in this release. (More details are

 available in the CVS log and trackers on SourceForge.)

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.

 maintainer of PDCurses. Plus, thanks to all who've reported bugs or

 requested features. Apologies to anyone I've forgotten.

 I've tested this version 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.
