With TEXTCOLOR disabled, compiler warnings about term_start_color()
and term_end_color() not being declared were followed by link failure
because they weren't available.
This tries to simplify color handling in the tty status code without
resorting to #if TEXTCOLOR (the proper fix, but somewhat intrusive).
For the usual case where TEXTCOLOR is defined, there were instances
of
if (color != NO_COLOR && color != CLR_MAX)
term_start_color();
...
if (color != NO_COLOR)
term_end_color();
and also of
if (color != NO_COLOR)
term_start_color();
...
if (color != NO_COLOR)
term_end_color();
I've changed both types to be
if (color != NO_COLOR && color != CLR_MAX)
term_start_color();
...
if (color != NO_COLOR && color != CLR_MAX)
term_end_color();
so that start/end pairing will always be consistent.
Also, ((color_and_attr & 0xFF00) >> 8) might not work as intended if
using 16-bit int and color_and_attr happened to have its sign bit set.
Change to ((color_and_attr >> 8) & 0x00FF) to ensure just the desired
bits.
Also also, a couple more formatting bits.
Started by removing two or three unused variables, ended up cleaning
up a lot of formatting (tabs, trailing spaces, indentation, a few
wide lines, 'if (test) return' on same line). Marked some static
functions as static in their definitions instead of leaving it hidden
in their prototypes. Moved a pair of short-circuit checks to skip
several initializations.
When a getlin() response is being typed, it wraps to second line if
the cursor tries to go past COLNO-1, but if a previous response is
treated as part of the prompt, using pline() to write prompt+space+text
wraps at a whole word boundary. tty's getlin() assumes that the screen
position can be derived from that prompt+space+text_so_far but that
doesn't match if wrapping at a word boundary leaves blank space at end
of the top line.
When a prompt is accompanied by default answer, output the answer
separately instead of pretending it is part of the prompt. Line-wrap
should occur at same point as when it was originally typed and avoid
the confusion about how far to back up when deleting characters.
This hasn't been exhaustively tested but it seems to work correctly
for ordinary input, input erased one character at a time, and input
killed all at once. One thing which definitely hasn't been tested is
having the prompt itself be so long that it needs to wrap.
After about the third time typing '#' and getting a prompt of "# K", I
decided that it wasn't clumsy typing. The call chain for get_ext_cmd()
was passing an uninitialized output buffer to [hooked_tty_]getlin()
which treated random junk as the previous result to be used as current
default. Other interfaces may need a similar fix.
ensure tty_curs() behaves the same whether DEBUG defined or not
when it comes to positioning the cursor.
The return statement, in the debug case only, was preventing
the cursor from being moved following a range check, so the
next output was written whereever the cursor happened to be
previously.
The messaging that detects the failed range check will get
written in the DEBUG defined case hopefully allowing resolution
to the range check failure, but now the cmov will still
be attempted just as it is in the case where DEBUG is not
defined.
Before this change, more-prompts and input text -prompts could not
be accepted with carriage return. Now, just like in menus, carriage
return is treated the same as a newline.
To test, use 'stty -icrnl'
When built without STATUS_HILITES, don't treat highlighting options as
if they were unknown. This may need some tweaking; the feedback feels
a bit intrusive so perhaps 'statushilites' and 'hilite_status' should
just be ignored when not available.
'hitpointbar' now relies on wc2 handling instead of being conditionally
present.
I couldn't reproduce the reported problem of the "In what direction?"
being issued after the screen was cleared, but bypassing pline() in
favor of putstr(WIN_MESSAGE) for tty prompts did also bypass
if (vision_full_recalc) vision_recalc(0);
if (u.ux) flush_screen(1);
done in pline(). Inadvertent loss of the latter could conceivably be
responsible for the problem. If so, the escape code used by cl_end()
may be broken for somebody's termcap or terminfo setup since clearing
to the end of the line in the message window shouldn't erase the rest
of the screen.
Regardless, the prompting change also bypassed the ability to show
the prompt with raw_printf() if the display wasn't fully intialized
yet, so some change to the revised prompting was necessary anyway.
Switching back from putstr(WIN_MESSAGE) to pline() resulted in
duplicated entries in DUMPLOG message history, one with bare prompt
followed by another with response appended, so more tweaking was
needed. The result is use of new custompline() instead of normal
pline(). custompline() accepts some message handling flags to give
more control over pline()'s behavior. It's a more general variation
of Norep() but its caller needs to specify an extra argument.
Update DUMPLOG's message history to include player responses to
most queries. For tty, both getlin() and yn_function(). For other
interfaces, only yn_function() is covered. (It's intercepted by a
core routine that can take care of the logging; getlin() isn't.)
Also includes saved messages from previous session(s), for the
interfaces which support that (tty), to fill out the logging when
a game ends shortly after a save/restore cycle.
The tty interface was using pline() to display prompt strings.
Having 'MSGTYPE=hide "#"' or 'MSGTYPE=hide "yn"' in .nethackrc
would suppress many prompt strings (in the two examples mentioned,
entering extended commands or the vast majority of yes/no questions,
respectively) and generally lead to substantial confusion even if
done intentionally, so switch to putstr(WIN_MESSAGE) instead.
Rewrite 3.6.1's compress_str() to avoid peeking past the end of the
input string. This should eliminate the reported valgrind complaint.
The problem was noticed for post-3.6.0 code introduced [by me...] last
June, but it looks like it was present in the old code too.
Also, fix the wording in the paragraph about NUL in the keyhelp text.
tty_putstr() always passes non-message window text through compress_str(),
clobbering usage of two spaces to separate sentences. putstr()'s caller
ought to have more control over that (possibly via its hardly ever used
'attribute' arg?).
This is a modified version of Jason Dorje Short's key rebinding
patch, and allows also binding special keys, such as the ones
used in getloc and getpos.
One of the ways to play NetHack on nethack.alt.org is via a HTML
terminal in browser. Unfortunately this means several ctrl-key
combinations cannot be entered, because the browser intercepts
those. Similar thing applies to some international keyboard layouts
on Windows. With this patch, the user can just rebind the command
to a key that works best for them.
I've tested this on Linux TTY, X11, and Windows TTY and GUI.
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.
Add MG_BW_LAVA to mapglyph() instead of hijacking MG_DETECT. Used
to display lava in inverse video if color is disabled and lava is
using the same display character as water (which is the default).
(The use_inverse option must be enabled for tty to honor it. X11's
text mode doesn't care. Win32 does care but probably shouldn't--it's
not a case like tty where the hardware might not support it.)
This implements both MG_DETECT and MG_BW_LAVA for X11, but only if
the program is built with TEXTCOLOR enabled. Those should work even
when color is not supported, but I suspect that configuration is
unlikely to ever be used so didn't want to spend the time to figure
out how to do it. (The relevant data is overloaded on the color
data, so not available when TEXTCOLOR is disabled.)
The win32 revision is untested.
When --More-- was written to leftmost column of line 2 while the
hero was swallowed, after player acknowledged it and the top line
was cleared, the cursor ended up in the wrong place. I still
don't understand what in the world is going on here, but adding
'flush_screen(0)' after 'swallowed(1)' in docorner() makes the
problem go away. Why is the behavior different when --More-- is
in the first column than when it's anywhere else?
After that fix, I commented the whole thing out. The swallowed
optimization is just not significant enough to justify peeking at
core internals.
Core bit: prior to those two changes, I tried inserting 'bot()'
into swallowed(). It moved the mis-positioned cursor from the
end of the second status line to on the map just right of the
bottom right corner of the swallowed display. That didn't fix
anything, but I've left it in place. bot() to update status is
needed following cls(); now it happens before redrawing the map
instead of at some point after.
Start coloring after the space which follows the selection indicator
instead of on that space. The difference isn't noticeable when the
highlighting is just a color, but it is if that highlighting includes
inverse video or underline which visibly apply to spaces. So for
a - entry A
the old code produced
a -########
and this revised code produces
a - #######
where '#" indicates characters subject to menu coloring.
This reverts commit 2ff96797a8.
Since this pull request was made to the DevTeam, a commit has appeared
in the official repo's NetHack-3.6.0 branch which effectively does the
same thing: NetHack commit 98b5f58 (tty menu coloring) by PatR.
There was a report during beta testing that menu lines which were
displayed in color showed the whole line in color, unless/until an
item was selected or unselected, in which case the '-', '+', or '#'
was rendered in monochrome. The suggestion then was to redraw the
selection character in color, but I went the other way. Menu
entries will render the selector letter and selection indicator in
monochrome all the time, and only the text of the menu entry will
honor menucolors.
