Update tty command completion to ignore #shell and #suspend when
they're disabled. (Since they aren't flagged for command completion,
this should be unnoticeable.)
Update X11 extended command selection to not show shell and suspend
in the menu when they're disabled. (Trickier than I expected.)
X11 currently rejects #suspend (at run time, not compile time) but
allows #shell. If it was launched syncronously from a terminal
window, shell escape behaves sanely. Otherwise, that seems like
asking for trouble.
Both the "help" button at top and the "help" extended menu command
were hilighted by the X resources. Make the top buttons have
"btn_" prefix, so they're easily distinguished in the resources.
Due to the new player selection dialog I did, it was possible
to rename your character - but this didn't rename the lock files
and tried to load a save from the wrong name.
This is a bit of a hack, but seems to work and didn't seem to
cause problems for the tty.
A wishlist/TODO item: when "female" is highlighted, change "caveman"
to "cavewoman" and "priest" to "priestess". If it gets toggled to
"male", change them back.
This eliminates nearly 40 warnings, most by suppressing complaints of
used function arguments but a few for unused local variables. There's
also some reformatting thrown in....
There are still 18 warnings about uses of XtSetArg(), about assigning
const to non-const.
The dialog shows the player's name, race, role, gender, and
alignment in a single window, similar to the Qt4 dialog.
Also allows randomizing the character selection.
Use the dialog by setting OPTIONS=player_selection:dialog
Umpteenth revision of the X11 extended command menu. Add a new
resource to NetHack.ad to control its initial size.
I still hope there's a better way to do this, but this is my last
shot at it.
When the extended command menu auto-scrolls as the player types in
characters, scroll so that all matching entries come into view rather
than just the first one. For example, it someone types 'w', instead
of just highlighting and showing "wipe", it will highlight "wipe"
(because that has become the default response when <return> is used)
but also show "wiz-this", "wiz-that", and "wmode". It actually shows
one extra entry beyond the last matching one--so you can see that
there aren't any more ambiguous choices--except for 'w' where "wmode"
is the very last extended command.
Previously, on subsequent popups of the extended command menu, the
scrollbar's slider was left drawn in the position it was in during
the previous time even though menu content wasn't scrolled. Now it's
forced back to the top (non-scrolled) position when that menu is
popped up.
When the extended command menu is big enough to need a scrollbar,
leave more elbow room when forcing its height to fit on screen.
The last entry was frequently obscured by OSX's "docking tray"
desktop decoration and the resize hotspot (bottom right corner of
the menu popup) could be hard to access.
I'm not particularly happy with this code. There really has to be
a better way to accomplish what's needed.
I upgraded from OSX 10.5.8 via 10.6.3 to 10.6.8, plus Xcode to whatever
version was on the 10.6 dvd, and ended up with a more recent version of
gcc that is configured to use 64 bit longs and 64 bit pointers (by
default; presumably that can be changed if necessary). It triggered
several warnings about converting int to pointer of different size or
vice versa even when explicit casts were in use, and a couple of other
things.
The big memory allocation for tiles that was unfreed according to
heaputil was actually freed by X according to a comment in the code.
But free it explicitly for #if MONITOR_HEAP so that the alloc/free
tracking stays accurate.
Also, the cached extended commands menu was not being freed, so take
care of that. I wasn't sure where to handle it; I ended up making it
happen when the map window is torn down.
X11 had been ignoring add_menu(..., MENU_SELECTED) to specify a
pre-selected menu entry. This adds support for that.
Attempt to implement pre-selected entry for PICK_ONE menu sanely by
returning the pre-selected entry instead of toggling it off if the
user chooses it explicitly. Inner workings of menus are convoluted
so I'm not sure it's 100% correct, although testing hasn't found any
problems. (tty currently returns 0 for "nothing picked" when
explicitly picking a pre-selected entry in a PICK_ONE menu, and the
core jumps through hoops to handle it. That can't be cleaned up until
all interfaces which support pre-selected entries achieve sanity.)
Make "random" be chosen for <return> or <enter> during role selection
and highlight it to reflect that. (Role selection for X11 uses its
own code instead of nethack menus, so pre-selection isn't applicable.)
Without this, the keyboard commands don't work in the extended
command window on Linux. If the translations are removed from
menuformview, then the keyboard commands don't work on Mac.
Having the translations in both doesn't seem to hurt.
When entering an extended command, allow the user just type
and match a new command immediately, if no match was found,
instead of needing to wait the 2.5 seconds.
Restore the ability to select extended commands by keystroke.
The key translation stuff had gotten attached to the wrong widget.
When using keys to highlight an entry in the extended command menu,
don't reset the key-by-key handling so quickly. (On second and
subsequent keystrokes, if you waited more than 0.5 second, the new
key started picking an extended command from scratch rather than
continuing the current one, making it pretty hard to disambiguate
commands which have the same initial letter. Now the delay
threshold is 2.5 seconds. In theory that should become a user-
preference resource but I don't think it's worth the effort.)
Display the help choice in response to '?'.
Clean up the formatting of the top two buttons (dismiss + help).
Start with a scroll bar if the menu is too big to fit on the screen.
Prior to this, on OSX, the full menu would be constructed but any
of it that was 'displayed' beneath the bottom of the screen was
inaccessible because it couldn't be dragged higher and couldn't be
resized to get a scroll bar (since the way to resize on OSX is by
dragging the bottom right corner--which was off the screen).
The problems I mentioned recently are still present: when scroll
bar is present, I can click beneath it and it moves down, but
neither dragging it up nor clicking above it will move it back up.
Fortunately the recently implemented up and down arrows both work,
even after clicking/dragging starts failing.
There was a lot of trial and error involved here. Most of it
eventually got phased out, but the mystery of 'defaultDistance'
(which is reported to be 0 but is actually 4) remains. The screen
height stuff at the end ought to be fixed up if someone can figure
out how to get the width of a horizontal scroll bar or the height
of a title bar. (I'm sure I used to know how to do the latter,
but that was 25 or so years ago, and in Fortran with Xlib rather
than Xt or Xaw....)
I'll push a formatting guide at some point. There may still be
outstanding changes, but please feel free to resolve those as you arrive
a them.
To the best of my knowledge, there is no changes to the actual code
content, but the formatter does have the occasional bug. If you run into
an issue, please fix it!
Suppress close to 400 warnings generated by gcc on the win/X11/*.c code,
most due to -Wwrite-strings which makes string literals implicitly have
the 'const' attribute. (Since modifying a string literal results in
undefined behavior, that is an appropriate check to have enabled, but
it can be troublesome since string literals have type 'char *' and code
that uses them that way is correct provided it avoids modifying them.)
113 warning: initialization discards qualifiers from pointer target type
127 warning: assignment discards qualifiers from pointer target type

The nhStr() hack casts to 'char *', explicitly removing 'const', for
situations where it isn't feasible to make code directly honor const.
The vast marjority of uses are for the second parameter to XtSetArg(),
which is a macro that actually performs an assignment with the second
argument rather than passing it in a function. It takes values like
'XtNtop', which doesn't need to be altered (although in many places I
changed that to nhStr(XtNtop) for uniformity with the surrounding code,
and 'XtNbottom', which does need to have the extra const stripping to
avoid a warning. Go figure.
The nhUse() hack actually uses its argument in a meaningless way if the
code is compiled with FORCE_ARG_USAGE defined. When GCC_WARN is defined,
FORCE_ARG_USAGE will be enabled if it hasn't been already. Example:
/*ARGUSED*/
int foo(arg)
int arg; /* not used */
{
+ nhUse(arg);
return 0;
}
The extra line will expand to ';' when FORCE_ARG_USAGE is not defined
or too
nhUse_dummy += (unsigned)arg;
when it is. I figured direct assignment might lead to a different
warning by some compilers in a situation like
nhUse(arg);
nhUse(otherarg);
where the first assignment would be clobbered by the second, and using
bitwise operations or safer '+= (arg != 0)' would most likely generate
more non-useful code. Some tweaking might turn out to be necessary.
I noticed a few panic messages contained newlines, and one included a naked
carriage return. panic() adds a newline itself, and also generally ensures
the message will be on a new line (the initial "oops" ensures the message
itself will be on a new lines). This patch removes the unneeded characters.
Too much code was being shared between the extended command window
and the popup dialogs for player selection, causing an uninitialized
variable to be referenced, often resulting in a core dump.
