I was experimenting with some potential changes to menu searching but
have not been satisfied with the result. However, this bit of code
consolidation is worthwhile regardless of that.
Restore handling for keystrokes on PICK_NONE menus so that scrolling
via keys works for them. (That handling was disabled as part of the
patch to support MENUCOLORS.)
Enable [cancel] button for all menus. (That had apparently been
grayed out for PICK_NONE menus since day 1 for X11 windowing.)
Previously the code used the ASCII Text Athena widgets for displaying
file contents. Unfortunately, the widget made it impossible to control
scrolling or pretty much anything else.
Use the menu code instead, making the file display window behave properly.
The core wants to reuse the permanent inventory window for choosing
an object from inventory, but the perm_invent window could be
hard to focus - it could even be on another display!
Instead, create a temporary new window from which the user can
pick an inventory item.
Replace the XawList with our own lists of labels and command widgets
to allow for menucolors. Supports only inverse line attribute for now.
Allow key translations to work with menus on Linux.
Bug report #H7156 listed three items, all relating to perm_invent:
1) it shouldn't persist across save/restore since restore might be
on a system which doesn't have enough room to display it (report
actually complained that config file setting was ignored when
restoring old games, which is an expected side-effect for options
that persist across save/restore);
2) permanent inventory wasn't updated when using scroll of charging;
3) attempts to update permanent inventory during restore could lead
to crash if it tries to access shop cost for unpaid items.
Items (2) and (3) have already been fixed. This fixes (1).
Replace 'flags.perm_invent' with a dummy flag, preserving save files
while removing it from flags. Add 'iflags.perm_invent' to hold the
value of the perm_invent option.
The win32 files that are updated here haven't been tested. Whichever
branch contains the curses interface needs to be updated; ditto for
any other pending/potential interfaces which support perm_invent.
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.)
Make the six buttons (ok, cancel, all, none, invert, search) on
menus for X11 all have the same width.
'ok' should probably be changed to 'okay' to be consistent with
X11_getlin(). (Another inconsistency: the extended commands
menu uses 'dismiss' rather than 'cancel'.)
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
29 warning: passing argument discards qualifiers from pointer target type
109 warning: unused parameter
12 warning: comparison between signed and unsigned
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.
Convert search in tty menus from pmatch to case-insensitive pmatchi;
convert search in X11 menus from substring strstri to wildcard pmatchi.
tty bug: if the menu is full screen, the search prompt and subsequent
user input clobbers the menu header.
Same functionality as was recently implemented for tty. If a
character like ':' is an explicit menu selector and the player
types it, select that menu entry rather than treating it as a
search request. (Same for other menu commands like '>', but
offhand I can't think of anything besides container looting's
': - look inside' that uses any non-letter selectors other
than '$', which isn't used as a menu meta command.)
When GOLDOBJ is defined, dropping partial amounts of gold using the D
command would not work because gold currently has the same inventory letter
as the coin group accelerator. In this case, the group accelerator should
not be used, since it confuses counts. tty and X11 ports are fixed. The
tty change should fix the Windows console version as well (untested).
