Reported directly to devteam last October, for 3.4.3 on NAO,
subject "UI flaw in message history":
"Applying the stethoscope at self informs:
"Status of Xxxxxxxx (piously neutral): Level 14 HP 138(138) AC -15, very
"fast, invisible.--More--
This is reproducible with shorter character name "wizard" by being
"nominally neutral" or "nominally chaotic". I had a 2 digit level
but didn't notice that my AC took up only 1 digit and ended up
using 125ish blessed potions of full healing to get 4 digits of hit
points in order to get the line to wrap between "very" and "fast".
"But the message history with Ctrl-P shows:
"Message History
"
"Status of Xxxxxxxx (piously neutral): Level 14 HP 138(138) AC -15, very
"invisible.
The key was "Message History", indicating msg_window:full or other
setting which causes ^P to bypass the top line message window and
use a general text window to deliver all history lines at once.
The original feedback splits the line by replacing the space
between "very" and "fast" with a newline, which topline handling
notices and processes as special, but then leaves in place.
msg_window:full results in tty_putstr() case NHW_TEXT, which treats
newline as an ordinary character since it doesn't expect to see
that in text. Squeezing out three doubled spaces made room for
"very\nfast," on the top line. process_text_window() attempted to
write it there, but putchar() wrote up through "very," on one line,
then output the newline which resulted in "fast," on the next line.
Then explicit cursor positioning set things up to put "invisible"
at the start of that line, overwriting "fast," so making it appear
to be missing.
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!
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.
This reverts commit 7f0f43e6f9 and some related
subsequent commits.
This compiles, but I have not done extensive testing.

Hide most of the Unicode support in tty's top line manipulation.
The new code is somewhat fragile, but the clutter from the many instances
of #if UNICODE_WIDEWINPORT was making it difficult to work on some other
changes.
[Make use of recent message history changes.]
Add support to makedefs and the core for including a line of summary
text with quest messages that don't use pline() delivery. The multi-line
record structure of quest.txt begins each entry with %C and ends with %E.
makedefs now examines the %E lines looking for "[anything]" and adds that
to quest.dat where deliver_by_window() can find it. The square brackets
are required in the input and intentionally carried along to the output.
putmsghistory() is used to put the summary text into the message history
buffer for use by ^P, without being displayed first. (So this is a no-op
for interfaces which haven't implemented putmsghistory yet. Maybe
genl_putmsghistory() should pass such text to pline() as a quick hack?)
This adds a few summary lines to quest.txt so that the feature can
be tested. Most of them were written by <Someone> nearly three years
ago. I'm planning to add a couple of new control codes that'll allow some
of them to expand into shorter text. (The one where the Archeologist
leader tells you that the nemesis stole the artifact so your mission is
to find the goal level, defeat the nemesis, and return with the artifact
ends up being roughly 160 characters long.)
[Third of three message history patches.]
Add another argument to putmsghistory() so that it can tell whether
it's processing multiple messages for restore (which should be treated as
being older than any current messages) or a single message to stuff into
history (which should be treated as the most recent message even though
it hasn't been displayed in the message window).
Explicitly truncate the query prompt string to QBUFSZ-1 characters.
For tty and Amiga, no longer include the choices and default within that
length limit; use a bigger buffer to hold them along with the prompt.
[See cvs log for doc/window.doc for more details.]
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.
<Someone> discovered that it is possible to
have wins[WIN_MESSAGE] be null during
a hangup, not sure why yet.
Put a guard in to prevent de-referencing a null pointer.
1. Switch to low-level console routines for performance improvements.
2. Instead of moving the cursor around like a real tty, just track the
destination coordinates of where the cursor should be, and
defer the movement until user input is expected.

This seemed like a reasonable request. This patch:
- adds the core support required.
- adds the tty supporting routines.
by <Someone>
(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.
- typing ESC would lose messages if msg_window was not displayed
- incorporate <Someone>'s fix, which causes them to be tracked, just not
displayed, and thus still available for ^P viewing later on
- 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
If you interrupt nethack (^C) in tty windowport mode while a pompt is
displayed and and msg_window=true, it can display the full message history
at an unexpected time. Detect this and display only the topl, as expected.
