Fix filtering used by the 'D' command, and a few other activities that
allow both object class filtering and bless/curse state filtering, so
that when both class(es) and state(s) are specified, objects need to
match both rather than either. D?C will present the player with cursed
scrolls to drop rather than all scrolls plus all other cursed objects.
This also fixes another instance when gold could end up with its bknown
flag set.
are being flat-dumped into save file and this causes segfault in restore()
whenever data segment layout changes (e.g. global variables added/removed).
bmask should either be stored with the objects.
Allow the 'I' command to show inventory of known blessed items via
pseudo object classes B, C, U, and X. That's instead of an showing
inventory of specific object class. The two can't be combined
because 'I' operates on single character input.
I had to modify tty_yn_function to prevent it from forcing a BUCX
character into lower case (simply using lower case would cause a
conflict with 'u' and 'x' for inventory of shopping bill), and did
that by checking whether any of the acceptable response characters
are upper case. Pretty straightforward and shouldn't impact any
other uses that don't specify upper case choices.
I did the same thing for X11. Other interfaces most likely need
to do something similar. If they don't, a response of 'B' or 'C'
(for menustyle:traditional or menustyle:combination) will simply
not work, without causing any problems, same as typing an invalid
choice, and 'U' or 'X' will give shop feedback instead of the
requested subset of inventory.
The Guidebook revisions are untested.
When you turn on the automatic description of a glyph under cursor,
we want to show the short description of what glyph it actually is.
The long full description of all possibilities is far too long, so
may cause more-prompts, and is awkward for blind players.
Replace most uses of isspace() with a simple test for ' ' after
processing the string buffer with mungspaces (which replaces tab
with space, converts instances of consecutive whitespace into a
single space, and removes leading and trailing spaces). The uses
where this wasn't done now cast their argument to (uchar) so that
platforms with signed chars will never pass negative values to it.
I didn't mess with the menu coloring code (except for casts to the
isspace() argument); it almost certainly could benefit from using
mungspaces. I did mess with the symset processing quite a bit,
and hope I haven't accidentally broken anything. Default symbols
and DECgraphics symbols still parse and display ok, so the rest of
dat/symbols should be ok too. I didn't test symbols in the user's
config file because I don't remember how that's supposed to work.
Avoid initializer for auto-class array since many pre-ANSI compilers
didn't support that. Also, when ESC is used to cancel inventory
selection, don't continue on searching for that selection in invent.
Still doesn't address the reported stack corruption.
* 'alt' points to a buffer which has already been processed by
lcase(), so remove the redundant call to that routine;
* common error exit accessed via 'goto' could potentially leave
a dangling window structure (only if 'data' is corrupted though;
it's the only way a failure at that late point could occur).
I didn't find Michael's crasher, but I did find a couple of minor
problems:
knight's saddled pony wasn't found in the file lookup either though
there is an entry for pony ("tame saddled <foo>" stripped off "tame "
but not "saddled "; "saddled <foo>" would only be found of there was
a wildcard entry key of "*<foo>", like "*horse" to catch both horse
and warhorse);
"wombat" matched the bat entry rather than reporting an unknown
entity.
Remove the code that converted statues shown as monsters into stautes
shown as big rocks when saving and then reversed the effect when
restoring. It was done to preserve save file compatability with 3.4.3
where statue-as-monster glyphs didn't exist, so is no longer useful.
* remove several unreachable panic() calls; alloc() already panics
rather than return a null pointer;
* replace a couple of calls to malloc() with alloc() so that
MONITOR_HEAP won't produce spurious alloc/free discrepancies;
* replace several instances of variable 'd' with 'd0' so that it
doesn't conflict with the name of a function;
* comment out opvar_new_region() since it isn't used anywhere.
