Fixes#235
For initial options under curses, specifying 'DECgraphics' as a
boolean rather than as 'symset:DECgraphics' wasn't overriding the
new default 'symset:curses'. Since previously DECgraphics was
rejected for curses, it's possible that no one noticed.
Primary and rogue symbols were being set to default if primary hadn't
been given a value, possibly clobbering rogue symbols if those had
been given a value. Initialize them independenly.
Return early from curses_convert_glyph() if the value doesn't have
the 8th bit set since it now deals exclusively with DECgraphics
handling. Force a sane value for returning early on rogue level.
This time I'm putting things in as-is before making a few tweaks.
The pull request was three or four separate changes. I used the
patch instead so they've been collected into one commit.
Highlighting for monsters shown due to extended monster detection and
for lava shown in black and white didn't work because that keys off
of 'iflags.use_inverse' (actually a macro for 'iflags.wc_inverse') and
curses wasn't enabling that window-capability option. To be fair, it
was probably unconditional at the time the curses interface was first
developed. It checked for whether a monster was supposed to be drawn
with inverse highlighting but wouldn't draw it that way because the
flag was always false. Inverse b&w lava is relatively new and curses
hadn't been taught about it.
Various other things such as pets (if hilite_pet is on) and object
piles (if hilite_pile is on) get highlighted with inverse video when
use_color is off, regardless of whether use_inverse is on or off.
That's probably a bug.
Fixes#230
Incorporate github pull request #230, support for DECgraphics-style
line drawing in the curses interface. I've rewritten the
curses_convert_glyph() part so that it doesn't require C99 and
doesn't reinitialize its pair of arrays for every character written
to the map. The DECgraphics conversion is now a straight char for
char one, DEC line drawing code to ACS, without regard to what map
symbol is intended or what 'cursesgraphics' uses for that symbol.
Right button is button3 rather than button2. Accept either and treat
both as "not left" to pass CLICK_2 back to the core.
Treat <Ctrl>+left-click as "not left" too, to simplify usage with Mac
one-button mouse (where <Ctrl>+left-click can be configured to send
"secondary click" but might not be set do so) or one-button laptop
trackpad (where having two fingers on the scrolling portion of the pad
while clicking the button is necessary to send "secondary click").
Autodescribe feedback and multi-digit count prompts are always shown
on the last line of the message window and are suppressed from message
history (both ^P and DUMPLOG). When the message window is using all
available lines, the last one was being overwritten (until the count
or the feedback was completed or dismissed, then last line returned).
Adopt the suggestion that it be scrolled up a line instead of being
overwritten. [I haven't been able to reproduce the reported problem
where shorter overlaid text left some of longer underlying text visible
but that should now become moot.]
Bonus fix: while testing, I noticed that if your screen only has room
for a one-line message window and you used ESC to cancel 'pick a spot
with cursor' prompting before moving the cursor, the prompt was left
intact on the message line. tty erases it in that situation, but the
clear_nhwindow(WIN_MESSAGE) was a no-op for curses because it usually
doesn't erase old messages. This changes the curses behavior when the
core asks it to erase the message window: now it forces one blank line
of fake autodesribe feedback (causing the prompt or other most recent
message to scroll off top), then removes that fake feedback (leaving
a blank message line). For multi-line message window, the old messages
scroll up by one line sooner than they would when waiting for the next
real message but are otherwise unaffected.
curses uses 'reversed' (LIFO) style when displaying previous messages.
Use the existing (previously tty-only) 'msg_window' option to also
support 'full' (FIFO). The actual code needed as just a couple of
lines; tweaking options parsing and the documentation was more work.
Using ^P right after resize or 'O' of align_message, align_status,
statuslines, or windowborders would result in
'curses_display_nhmenu: attempt to display empty menu'
because some memory cleanup I added several weeks back was being
executed when the curses interface tore down and recreated its
internal windows.
This fixes ^P handling by making sure that that menu (which is just
text but uses a menu to support '>'/'<'/'^'/'|' scrolling) will never
be empty and it also fixes the window deletion to not throw away
message history until it's final deletion at exit time.
^P uses a popup window to display previous messages and it was never
deleting that window, just creating a new one each time. Same with
the routine which displays an external help file. Using either or
combination of both close to 5000 times would probably make internal
window creation get stuck in an infinite loop. Delete those windows
after they're used so it'll never be put to the test.
The memory cleanup I added for map/status/messages/invent was only
being preformed at end of game, not when saving. Fix that too.
More groundwork for overhauling the status display for curses, plus
a few functional changes. It was doing a full status update for
every changed field (except conditions), instead of waiting for a
flush directive after gathering multiple changes at a time. Since
it already does gather every change, the fix to wait is trivial.
This decouples 'hitpointbar' from 'statushilites'. When highlighting
is off, it uses inverse video only. When on, it behaves as before:
using inverse video plus the most recent color used to highlight HP
(which can vary if that has rules to highlight changes or percentage
thresholds) but ignoring any HP attribute(s). This also enables the
latent 'statuslines' option and changes 'windowborders' option from
being settable at startup only to changeable during play.
'statuslines' can have a value of 2 (the default) or 3 and applies to
'align_status:bottom' or 'top'; it's ignored for 'left' and 'right'.
At the moment, setting it to 3 only allows status condition overflow
to wrap from the end of line to 2 to the beginning of line 3, and if
window borders are drawn they'll clobber the last character on line 2
and first one on line 3. There's no point in trying to fix that
because it will go away when the main status overhaul changes go in.
Condition wrapping for vertical orientation (left or right placement)
was already subject to the same phenomenon and will be superseded too.
This also changes the meaning of the 'windowborders' value so could
impact players using source from git (or possibly beta binaries for
Windows, but not for OSX where curses interface wasn't included).
Old:
0 = unspecified, 1 = On, 2 = Off, 3 = Auto (On if display is big
enough, Off otherwise; reevaluated after dynamic resizing);
Unspecified got changed to 3 during curses windowing initialization.
New:
0 = Off, 1 = On, 2 = Auto;
0 gets changed to 2 for default value at start of options processing.
So old value of 2 is changing meaning and explicit old value of 3 is
becoming invalid. Implicit 3 changes to default 2. Explicit 3 could
be the subject of a fixup but there isn't much point since 2 can't
have a similar fix. Users who are using old 2 or explicit 3 will need
to update their run-time config files.
This adds 'statuslines' to the Guidebook and moves some other recently
added documentation of curses options from among the general options
(section 9.4) to "Window Port Customization options" (section 9.5).
None of them have been added to dat/opthelp which seems to be missing
all the wincap options.
Originally I made a lot of changes (mostly moving C99 declarations to
start of their blocks) to the old '#if 0' code at end of cursstat.c,
but have tossed those, except for one subtle bug that assumed 'int'
and 'long' are the same size.
Miscellaenous stuff either groundwork for or noticed while updating
curses status. The status changes themselves need some more testing.
One or two of the comments refer to that revised status which hasn't
been checked in yet.
This started out as an attempt to document the curses options in the
Guidebook, but I didn't actually get that far. Instead, integrate
the curses options better via more consistent WC/WC2 usage. This
prevents 'guicolor' from showing up as a boolean option for non-curses
interface in curses+other binary.
For curses itself, let 'petattr' be set/reset via 'O'. Also, accept
'Dim' as a possible pet highlight attribute since it already handles
all the other ordinary attributes. I'm not sure what leftline and
rightline highlighting are supposed to do. They were missing for
ncurses (or maybe they're misspelled for PDcurses?) but adding them
didn't produce any visible effect (using TERM=xterm-256color on OSX
with default font/character set).
Not addressed:
1) general confusion about compile-time vs run-time option filtering;
2) curses pet highlighting only works if 'color' option is enabled.
Back out '#include "date.h"' so that cursinit.c won't be recompiled
every time any other file(s) need to be compiled. It doesn't need
patchlevel.h either. There is already a straightforward way to fetch
the copyright banner lines from version.c.
The splash screen (ascii art spelling "NetHack" preceding the normal
copyright lines) was invisible when showing white text on white-ish
background. Make it honor !guicolor.
"Shall I pick a character's role, race, gender and alignment for you?
[ynaq] (y) " was too wide to accept the answer on the same line on
an 80-column display so "(y) " was placed on the second line. That's
constructed in the core; change the construction to omit " a" when
using "character" rather than a role name. (tty shortens it by omitting
the default " (y)"; with " a" gone, it could revert to normal prompt.)
Also a bit of lint cleanup and some reformatting of cursinit.c....
