SHORT-TERM TO-DO ITEMS:
Known Problems:
+* GNAT does not put libraries in the correct order, so a build only links
+ properly if you use shared libraries since -lncurses is first.
+
+* XPG4 specifies that the enhanced features are not available unless the
+ _XOPEN_SOURCE_EXTENDED test macro is defined by the application. Ncurses uses
+ this macro (incorrectly) to address a dependency upon wchar_t. The functions
+ which use wchar_t are not implemented, so the effect of the test macro is
+ pointless.
+
* 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.
-* Ncurses cursor movement does not make effective use of hard tabs, as SVr4
- does.
-
-* Scrolling optimization has holes: for example, the ncurses 'p' test, which
- exercises scrolling in a pad does not (1996/12/24) use scrolling regions.
- Also, running other tests shows that scrolling optimization forces repaints
- of the screen between calls to refresh().
+* 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.
-* The stacking order of windows on the screen does not match that implemented
- in SVr4 (e.g., Solaris curses). XSI doesn't specify a stacking order, so
- full compatibility for this behavior must be achieved by testing/analysis.
-
-* The ncurses 'o' test does not behave the same on SVr4 (Solaris) as with
- ncurses (the latter pops windows up more). The former also produces 20%
- fewer characters in a 'script' output. Further analysis is needed.
+* 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.
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
++ 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 (the
- actual code that does this is in ncurses/lib_options.c:add_keytry().
- This is a legacy terminfo property we can't mess with.
-
-* Recognition of xterm mouse reports is implemented by setting the kmous
- capability to the mouse-report prefix. As a result, the kmous sequence is
- eaten even when mouse recognition is disabled. This could be fixed if
- necessary with special code that pokes the kmous value back into the
- input FIFO when KEY_MOUSE is seen and the mousemask is zero, but that would
- be kind of ugly.

* The window classes defined in the c++ subdirectory need documentation.
Some C++ programmer could earn a lot of good karma by doing this...
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.
+ 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.
* The demo build for the c++ library craps out with many link errors under gcc
2.6.3. We're told the C++ support in 2.6.3 is broken and that the right
- fix is to upgrade to 2.7.0.
+ fix is to upgrade to 2.7.0. This demo is also known to not build with
+ the Sun SPARCworks 4.1 C++ compiler, due to a problem resolving templates.
* Under Ultrix, configure craps out (Ultrix sh is lame). Run it under ksh.
Then, run "make mostlyclean", remove config.* from the top-level directory
and configure for the cross-compiler.
-Untested features:
++ 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.
-* The rep optimization in lib_doupdate.c is not yet thoroughly tested.
+Untested features:
* The code for the HP color model using set_color_pair is untested.
