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!
On NAO, one of the major complaints was accidental escaping
from wishing prompt when using cursor keys. The users were
trying to go "back" on the entry to fix a typo, but lost
the wish instead.
This prevents escaping out of a text prompt if there is any
text entered into the prompt; pressing escape clears the prompt.
This reverts commit 7f0f43e6f9 and some related
subsequent commits.
This compiles, but I have not done extensive testing.

The presence of conditional code for both UNICODE_WIDEWINPORT and
NEWAUTOCOMP in hooked_tty_getlin() was making it be pretty hard to read.
This simplifies the UNICODE_WIDEWINPORT parts similar to what was done in
topl.c a year or two back. The NEWAUTOCOMP parts are still cluttered.
This compiles successfully with UNICODE_WIDEWINPORT enabled but that
configuration is otherwise untested.
The hangup check added to xwaitforspace() (which gets tty user's
response to --More-- and "Press Return to continue: ") wouldn't be good
enough if hangup occurred while that routine's input loop was executing.
NOSAVEONHANGUP isn't documented anywhere. I don't see why it should
wipe out recoverable level files just because it doesn't want to build a
save file out of them during the hangup. Leave them intact if checkpoint
is active. If someone really wants to make them always go away, they'll
need to disable INSURANCE as well as enable NOSAVEONHANGUP.
tty's getret() -> xwaitforspace() could get stuck in a loop after
hangup, depending upon the state of terminal shutdown (accepting EOF or
ESC cares about cbreak mode?). Make xwaitforspace() become a no-op during
hangup processing.
vms's call to hangup() from an exit handler took place after the
terminal has been reset (the exit handler for the latter is registered
later so executes sooner). Then exit_nhwindows() resulted in a second tty
reset attempt and settty() -> setctty() encountered an error (which it
reported, triggeting a getret() call). Make the vms code correctly guard
against multiple resets.
This patch attempts to add some levels of unicode support
to NetHack.
The master on/off switch for any Unicode support is
defining UNICODE_SUPPORT in config.h. Currently
there is code support for two subsets of unicode support:
UNICODE_DRAWING
If UNICODE_DRAWING is defined, then the data
structures used to house drawing symbols are expanded
to the size of wchar_t, big enough to hold unicode characters.
A typdef called `nhsym' is involved and if UNICODE_DRAWING
is defined, it is wchar_t, otherwise it is uchar.
UNICODE_WIDEWINPORT
If UNICODE_WIDEWINPORT is defined, then the data
structures inside the window port are expanded to the size of
wchar_t, big enough to hold unicode characters. Both map
symbols and text within the window port are expanded, in order
for potential support for displaying multinational characters some
day, but this patch only provides viewing of map symbols.
A typdef called `nhwchar' is involved and if UNICODE_WIDEWINPORT
is defined, it is wchar_t, otherwise it is char.
The only window port with code support for UNICODE_WIDEWINPORT
currently is the TTY port. Don't enable UNICODE_WIDEWINPORT
unless:
- it is a TTY port
- the underlying platform specific routines can
handle the larger data structures.
Don't enable UNICODE_SUPPORT unless:
- your compiler can handle wchar_t.
- your compiler can accept L'a' characters.
- your compiler can accept L"wide" strings.
Note that if your compiler can handle the above, you could
enable the larger data structures (currently if TTY) even if your
platform can't actually display unicode or UTF-8, by messing
with u_putch() in win/tty/wintty.c to only deal regular chars.
That should be the only function that actually pushes wide characters
out to the display.
If you enable UNICODE_SUPPORT, and your platform is capable
you will need to turn on the unicode run-time option to be able to
load unicode character sets from the symbol file, to be able to
push unicode characters to the display. You'll also want to load
a unicode symbol set once the unicode option is toggled on. In
a config file you would do that via these two lines:
OPTIONS=unicode
OPTIONS=symset:Unicode_non_US
The repository was stamped with NETHACK_PRE_UNICODE
prior to applying this patch, and stamped with
NETHACK_POST_UNICODE afterwards. The code differences
between those two tagged versions are this patch.
This is an initial round of SAFERHANGUP hangup changes. It introduces
SAFERHANGUP, provides the core framework, and enables it for UNIX.
Window-port changes are provided for win/tty, win/X11 and win/gnome. Qt
changes should be forthcoming after having Warwick look at them.
window.doc is updated so windowport maintainers have an clue what needs to
be done to support SAFERHANGUP.
The problem with the new autocomplete was tracked down to
be the result of differences between different implementations
of backsp(). The differences go all the way back to the
early MSDOS port by the look of it, and the win32,
and Mac tty ports all seemed to pattern themselves after the
MSDOS port for that routine. Apparently, it didn't cause any
harm until now.
The problem is that backsp() sends a character sequence
of 0x08, 0x20, 0x08 on at least those ports, where the Unix
tty code only sends 0x08. So the characters in the new
autocomplete were all being erased from the screen.
This patch only fixes the win32 tty port, so I've left the
conditional code in getline.c for DOS and Mac. I
Change tty extended command autocomplete, based loosely on <Someone>'s
patch, to allow you to type autocompleted characters. That is, you can type
characters the autocompleter inserted without invalidating the command.
I haven't looked closely, but at least some other windowport extended
command readers seem to already behave similarly.
I've found myself adding a trailing space to various extend
commands from time to time, and the program fails to recognize then
when that happens. It might be less likely once none of them has
any embedded spaces, but this wouldn't hurt anything if that becomes
the case.

(the following text accompanies the patch at <Someone>'s web page)
add more configurability to the new msg_window option of [..]3.4.0.
It allows the configuration option to take an optional parameter to
specify the style of message history display to use.
allows the following configuration options:
msg_window:s - single message (as was the default in 3.3.0)
msg_window:c - combination; two messages in 'single', then as 'full'
msg_window:f - full window; oldest message first
msg_window:r - full window reversed; newest message first
In the event of no parameter being provided,
the patch is compatible with the current 3.4.0 behaviour:
msg_window = 'full'
!msg_window = 'single'
msg_window can be configured for these options in the
Options menu (Shift-O)
msg_window stores the current window type in the non-persistent
iflags structure, which means that savefile/bones files should be
100% compatible with Vanilla, but at the disadvantage that your
customisations to msg_window will be replaced with your
defaults.nh (or ~/.nethackrc) value every time you restart a saved game.
Credits:
The patch draws inspiration (and code snippets) extensively
from <Someone>'s original msg_window patch, [...] as well as <Someone>'s code for reverse ordering implemented until recently in
Slash'em.
- attempt to determine if tty_wait_synch() is called during the ending
dialogs due to an interrupt, and not re-display the previous message
at the wrong time
- also, "msg_window display anomaly" fix was missing code to still treat ^P
properly while in a prompt
