SHORT-TERM TO-DO ITEMS:
Known Problems:
-* The form/menu libraries do not use wide-character features.
++ libtool does not work with GNAT.
-* Some users would like to build a single version of libtinfo which can be
- used from either libncursesw or libncurses.
-
-* libtool does not work with GNAT.

++ The screen optimization has been tested only in an ad hoc manner. We should
develop a good set of regression tests to cover lib_doupdate.c and
lib_mvcur.c.
-* Magic cookie support does not work, since the logic does not take into account
- refresh. Also, the initial optimize does not adjust the current location
- when a cookie is emitted.

++ Scrolling optimization has holes: for example, it forces repaints of the
screen between calls to refresh().
-* SVr4 uses slightly different rules for determining when softkeys are shown.
++ SVr4 uses slightly different rules for determining when softkeys are shown.
For example, they are initially displayed (before the ncurses 'e' test
activates them), and a touchwin can apparently also force them to be
displayed.
-* The code departs from perfect 8-bit cleanness in one respect; you cannot
- specify a character \200 as part of a capability string, because the terminfo
- library interprets \200 as a request to embed NUL (\000) at that point. This
- is a legacy terminfo property we can't mess with.

++ The window classes defined in the c++ subdirectory need documentation. Some
+ C++ programmer could earn a lot of good karma by doing this...
+
++ vid_attr() should support the set_a_attributes (sgr1) string, but does not.
+ There appear to be no terminals that require that functionality.
+
++ the configure --disable-ext-funcs option does not work for Ada95 tree.
+
++ the --with-pthread configuration builds for Cygwin, but does not work
+ properly (test/worm.c shows all of the worms in the same location).
-* The window classes defined in the c++ subdirectory need documentation.
- Some C++ programmer could earn a lot of good karma by doing this...
++ the --enable-rpath configure option builds for the corresponding platforms;
+ however combining it with --with-ticlib and --with-termlib does not always
+ produce libraries that can be run without setting environment variables.
+ Building those with libtool does not work either. (This is a problem with
+ the BSD platforms).
-* The resizeterm() function does not handle ripped-off lines such as that
- done for the slk_XXX functions.
++ more work is needed to make the MinGW port support ordinary terminals.
Portability (or lack thereof):
-* Users of older System V UNIXes (but not Solaris, and probably not SVr4)
- may trip over a known problem with the signal-handling code which causes
- abrupt termination of ncurses applications following resume from a ^Z
- suspend (this problem was first seen running lynx). You will not see
- this problem if you are running Linux or one of the 4.4BSD derivatives
- like FreeBSD, NetBSD, or BSDI. For details, see the analysis in the
- header comment of ncurses/tty/lib_tstp.c .
-
-* In theory, vwprintw and vwscanf are supposed to use the older varargs.h
- interface for handling variadic argument lists. Linux doesn't have
- varargs.h, it has the newer X/Open-standard stdargs.h equivalent. So
- these functions use stdargs instead. This is unlikely to be a problem
- unless you're building ncurses on a System V old enough to only have
- varargs.h. (Solaris 2.5.1 uses the stdarg.h binding as well).
-
-* If you're using a BSD earlier than 4.4BSD, or a Linux old enough not to
- have a native vsscanf(3) in its library, vwscanw() will not work. You lose.
- (It should work on any System V, however). If you want to fix this, add
- an implementation to ncurses/vsscanf.c.
-
-* The C++ binding fails to build with a few C++ compilers, mainly with
- configure script problems with vsscanf().
-
-* terminfo.5 does not format with the SunOS (and most other platform's) tbl
- utility because it relies on a diversion for each table entry. Get the groff
- package.

+There is an XPG4 standard released in 1996 which describes a superset
of the SVr4 API. The library is BASE conformant with this standard.
We would like to make ncurses fully conformant at the EXTENDED level
supporting internationalization.
2. DOS port

a small number of core files to produce a functionally-compatible
port that would do updates to a memory-mapped screen area. The first
result of this would be a DOS port.
