PDCurses_3_3

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.
