number_pad==1 adds
'5' => 'G'
M-5 => 'g'
'0' => 'i'
number_pad==2 swaps 5 and M-5 and adds M-0
'5' => 'g'
M-5 => 'G'
'0' => 'i'
M-0 => 'I'
M-5 and M-0 were missing from the bound key handling; they still
used hardcoded digits even though the actions for plain 5 and
plain 0 can be bound to other keys these days. This implements
the M-5 variation as NHKF_RUSH2. Changing numpad from 1 to 2
or vice versa will swap the NHKF_RUN2 and NHKF_RUSH2 actions
regardless of what keys they're assigned to. I haven't done
anything for unimplemented NHKF_DOINV2 though (and am not
planning to in case someone else wants to jump in...).
This also fixes the description of the 'I' command. The extended
command name for that still misleadingly refers to "type" rather
than "class" though.
While testing some addtional ?i (list of key assignments)
changes, I wanted to give every key a binding. When I tried
BIND=M-^A:exploremode
the text to key conversion didn't like that. This adds support
for M-^x and M-C-x plus variations where dashes are omitted.
This adds support for ^? even though that isn't really a
control character. I bound #terrain to it and surprising--to
me at least--the <delete> key worked to invoke that command.
Also changes 'char txt2key(...)' to be 'uchar txt2key(...)'.
Provide a hook to inhibit unixconf.h from defining SUSPEND
without the need to modify it: #define NOSUSPEND in config.h
or add -DNOSUSPEND to CFLAGS. Similar to long-standing NOSHELL
for inhibiting SHELL.
I started activating new program_state.saving and discovered that
saving of ball and chain could access freed memory. The change
for the former and fix for the latter are mixed together here (but
easily distinguishable).
The saving flag inhibits status updating and perm_invent updating,
also map updating that goes through flush_screen(). That should
fix the exception triggered after an impossible warning was issued
during a save operation. impossible() goes through pline() which
tries to bring the screen up to date before issuing a message.
During save, data for that update can be in an inconsistent state.
The code to save ball and/or chain when not on floor or in invent
(I think swallowed is the only expected case) was examining the
memory pointed to by uball and uchain even if saving the level had
just freed floor objects and saving invent had just freed carried
objects. So for the usual cases, stale pointer values for uball
and uchain would be present and checking their obj->where field
was not reliable.
Move the core's global restoring flag (not the same as main()'s
local resuming flag) to a more logical place. Add a saving flag
in the process, but it isn't being set or cleared anywhere yet.
(Once in use it will probably fix the exception during save that
was just reported, but before that it would be useful to figure
out what specifically caused the event.)
The program_state struct really ought to be standalone rather
than part of struct g but I haven't made that change.
Removing an unused variable for wishing and some reformatting
that whent along with it got mixed in. Removes some trailing
whitespace in sfstruct.c too.
Only lightly tested...
