Have the curses interface save and restore message history for use
by ^P. It doesn't spit the saved messages out into the visible
message window after restore; that's too distracting.
Using ^P right after resize or 'O' of align_message, align_status,
statuslines, or windowborders would result in
'curses_display_nhmenu: attempt to display empty menu'
because some memory cleanup I added several weeks back was being
executed when the curses interface tore down and recreated its
internal windows.
This fixes ^P handling by making sure that that menu (which is just
text but uses a menu to support '>'/'<'/'^'/'|' scrolling) will never
be empty and it also fixes the window deletion to not throw away
message history until it's final deletion at exit time.
^P uses a popup window to display previous messages and it was never
deleting that window, just creating a new one each time. Same with
the routine which displays an external help file. Using either or
combination of both close to 5000 times would probably make internal
window creation get stuck in an infinite loop. Delete those windows
after they're used so it'll never be put to the test.
The memory cleanup I added for map/status/messages/invent was only
being preformed at end of game, not when saving. Fix that too.
Miscellaenous stuff either groundwork for or noticed while updating
curses status. The status changes themselves need some more testing.
One or two of the comments refer to that revised status which hasn't
been checked in yet.
The curses interface was ignoring video attributes (bold, inverse, &c)
when color is toggled off or if built with TEXTCOLOR disabled. Honor
attributes regardless of whether color is displayed.
Also, toggling 'hilite_pet' On during play wouldn't do anything if the
curses-specific 'petattr' option had been left as None. (It worked as
intended if set in starting options.)
This started out as an attempt to document the curses options in the
Guidebook, but I didn't actually get that far. Instead, integrate
the curses options better via more consistent WC/WC2 usage. This
prevents 'guicolor' from showing up as a boolean option for non-curses
interface in curses+other binary.
For curses itself, let 'petattr' be set/reset via 'O'. Also, accept
'Dim' as a possible pet highlight attribute since it already handles
all the other ordinary attributes. I'm not sure what leftline and
rightline highlighting are supposed to do. They were missing for
ncurses (or maybe they're misspelled for PDcurses?) but adding them
didn't produce any visible effect (using TERM=xterm-256color on OSX
with default font/character set).
Not addressed:
1) general confusion about compile-time vs run-time option filtering;
2) curses pet highlighting only works if 'color' option is enabled.
Move the curses global variable defininitions to cursmain.c.
Make the references to those global variables extern in
include/wincurs.h
Get rid of a warning:
../win/curses/cursmesg.c:379:9: warning: declaration shadows a
variable in the global scope [-Wshadow] int orig_cursor = curs_set(0);
Kludge for Visual Studio compiler: Add a stub- file for use
in Windows curses port builds to ensure that a needed #pragma
is invoked prior to compiling the file pdcscrn.c in the
PDCurses source distribution. All command line options and
compile of the file. It is unreasonable to expect a NetHack
builder to have to tinker with the PDCurses source files in
order to build NetHack. This kludge means the NetHack builder
doesn't have to.
The file stub-pdcscrn.c contains only two lines:
#pragma warning(disable : 4996)
#include "pdcscrn.c"
Some day, if the PDCurses sources corrects the issue, this
can go away.
