Instead of using index() macro defined to strchr, use C99 strchr.
Instead of using rindex() macro defined to strrchr, use C99 strrchr.
If you want to try building on a platform that doesn't offer those
two functions, these are available:
define NOT_C99 /* to make some non-C99 code available */
define NEED_INDEX /* to define a macro for index() */
define NEED_RINDX /* to define a macro for rindex() */
(user-side decisions really, but as it stands right now
user-side decisions/options are made and processed by the core)
add a parameter to add_menu so color can be passed
While testing the new mouse action menus, it was quite annoying
to try and hit some shorter entries. Make all the selectable entries
the same maximum length, and with text left justified.
Catch up with tty and curses. Menu items flagged as skip-invert will
not be toggled On by select-all and select-page. If menuinvertmode
is 2 they also won't be toggled Off by deselect-all and deselect-page.
I don't try to toggle 'number_pad' very often, but when I do I almost
always type '0' instead of 'a' for Off or '1' instead of 'b' for On
on the first attempt. The menu shows
| a - 0 (off)
| b - 1 (on)
| c - 2 (on, MSDOS compatible)
| d - 3 (on, phone-style digit layout)
| e - 4 (on, phone-style layout, MSDOS compatible)
| f - -1 (off, 'z' to move upper-left, 'y' to zap wands)
This change makes '0' through '4' be undocumented group accelerators
for 'a' through 'e' (and '5' for 'f') in the sub-menu put up by 'O'.
tty and X11 worked as-is for '0' and required what amounts to a pair
of one-line changes to handle the other digits.
It doesn't work for curses and Qt (no idea about Windows GUI) because
they insist on treating any typed digit as the start of a count even
if one or more menu entries include that digit as a group accelerator.
(They also fail to support '0' as the group accelerator for iron-ball
class in the menu for multiple-drop.)
Change the '|'/#perminv final positioning for X11 to be the same
as for curses: finishing with <escape> leaves the current view,
with <return> resets to unscrolled.
Actually getting ESC and RET to the right place wasn't trivial;
down the rabbit hole and out the other side. Using yn_function()
to get the #perminv keystrokes is less than ideal. (curses also
started that way but switched to raw character input for this.)
Add new '|' command, aka #perminv, which allows the player to
send menu scrolling keystrokes to the persistent inventory window.
Implemented for X11, where its usefulness is limited, and for
curses, where it is more needed and also more fully functional.
The interface can either prompt for one keystroke, act upon it,
and return to normal play, or it can loop for multiple keystrokes
until player types <return> or <escape>. X11 does the former if
the 'slow' application resource is False so that prompting uses
popups, and the latter when 'slow' is True where prompting is in
a fixed spot and doesn't end up causing the persistent inventory
window to be stacked behind the map window. curses always does
the loop-until-done approach. It also accepts up and down arrow
keys to scroll one line at a time.
Also adds two new menu scrolling commands, menu_shift_right (key
'}' by default) and menu_shift_left ('{') if wincap2 flags contain
WC2_MENU_SHIFT. Shifting allows different substrings of too-long
lines to be seen.
For X11, neither works because their handling requires a horizontal
scrollbar and for some reason that escapes me our menus don't have
one of those. If they did, shifts could work for all menus but a
shifted window would hide the selection letters. So shifting would
be most usefully done as: pan right, read more of any long lines,
immediately pan back to the left.
For curses, they only apply to the persistent inventory window.
Shift right redraws it with class headers and inventory letters
shown normally but the item descriptions omit their leftmost
portion, showing more text towards the end. Shift left reverses
that and does nothing if the beginning is already in view. Forward
and backward scrolling while shifted leave the shift in place.
Looking up scrollbars did not work as intended. The code wanted an
ancestor widget that had both horizontal and vertical scrollbars,
but menus either have none or just vertical. The lookup code found
some top level widget and returned bad data.
In a couple of places, call menu_popdown instead of duplicating
its contents. I'm fairly sure that executing the is_active bit
that the duplications omitted is safe.
Several minor formatting bits are mixed in.
When persistent inventory window is up, remove it if 'perm_invent'
option gets set to False. This has a side-effect of fixing the
end-of-game prompting problem it caused.
further adjustments to the window port interface to pass a pointer
to a glyph_info struct which describes not just the glyph number
itself, but also the ttychar, the color, the glyphflags, and the
symset index.
This affects two existing window port calls that get passed glyphs
and does the parameter consistently for both of them using the
glyph_info struct pointer:
print_glyph()
add_menu().
The recently added glyphmod parameter is now unnecessary and has been
removed.
Provide a way to communicate additional behaviors and/or appearances
desired from NetHack window port menus.
This is foundation work for changes to follow at a future date.
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

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.
