DEC C in one of its non-ANSI modes didn't like
fieldorder = test ? &array1 : &array2;
It first complained that '&' applied to an array has no effect (which
was typically true in pre-ANSI environments) and once those '&'s are
ignored, the attempted assignment didn't match the variable's type.
That code was actually more complicated that it needed to be; slightly
simpler code works as intended.
The curses interface wouldn't build with HILITE_STATUS disabled. I
started adapting it to handle genl_status_update() but that was taking
too much effort with each niggling detail leading to another. This
goes the opposite direction: forcing the old STATUS_VIA_WINDOWPORT
behavior without having that #define available. That dragged along a
bunch of unexpected changes too.
window.doc states that the colormasks argument to status_update() is
only relevant for BL_CONDITION, but curses was relying on it to be
passed for BL_FLUSH as well. Yesterday's changes stopped the latter
and broke highlighting of status conditions. Other interfaces appear
to honor the description in window.doc.
The unresolved "first problem" mentioned earlier in commit
382286cb99 was caused by stale values
in status fields which had become disabled. Polymorphing left an
old BL_XP value and returning to original form left an old BL_HD one.
They weren't displayed but the stale value was included in the line
length calculation, resulting in 4 or 5 columns being set aside for
a phantom value. That implicitly reduced the available length of the
line and could result in extra spaces separating other fields being
squeezed out while unused spaces remained at the end of the line.
Experience points, time, and score didn't trigger this problem because
they were being explicitly excluded if disabled. So stale values for
them when they had been enabled then later disabled didn't matter.
I noticed a couple of things wrong--that I was fairly sure that I
had working correctly before--and after fixing the second one, the
first has mysteriously disappeared.
First problem, which may or may not still be a problem: extra spaces
were being removed from the second line of 2-line status even though
there were still 4 or 5 available spaces to the right of the status
conditions. It was behaving as if it thought the line was narrower
than actual size, or conversely, that the sum of the widths of the
fields plus the extra spaces was bigger than it actually was.
Second problem, fixed here. The code to put '+' in the far right
column of the last status line when there is at least one condition
all the way off the display wasn't working right when windowborders
were displayed. That's down to curses wrapping to the next line but
user can't see it due to the window border overwriting. Single char
overflow stayed on same line, but two or more wrapped and then the
'x' coordinate didn't match tests for 'too wide'. Perform explicit
truncation instead of leaving that up to curses. Also truncate
encumbrance when warranted since it's feasible for it to overflow.
Anyone using a display narrower than 80 columns might still run
into odd status behavior because other fields than conditions and
encumbrance could go past the end of line. But they shouldn't be
wasting screen real estate with windowborders, and without borders,
curses will keep the cursor in the bottom right corner when the
program tries to go past, which should keep things reasonably sane.
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.
I've overhauled the status display for curses. Horizontal layout
supports both 2 lines and 3 lines which can be changed dynamically
via using 'O' to set 'statuslines'. Fields are spread out a little
more than they used to be, making it more readable--at least to me--
but the extra spaces get squeezed out when lines become too long.
If 'showexp' is on and either conditions or hunger+encumbrance go
off the right edge, experience points are suppressed (but the option
is left on, so they'll come back once there is room).
For traditional 2-line hozizontal status, if hunger+encumbrance+
conditions go off the right edge even after experience points are
knocked out, there will be a '+' in the rightmost column if there
are any conditions that are all the way off. At present it doesn't
use the tty method of switching to abbreviated condition names to
reduce their legnth. I'll probably tackle that eventually if no one
beats me to it.
For 3-line horizonal status, there was an older implementation (but
disabled via #if 0) with gold and score moving to the third line.
(I'm not sure how status conditions were handled.) This one ignored
that and modified 2-line from scratch, moving alignment from line one
to line 2 and level description, time, and conditions from line 2 to
line 3. It looks like this (view with a fixed-width font...).
Wizard the Hatamoto St:16 Dx:15 Co:18 In:8 Wi:11 Ch:7 S:25
Lawful $:21 HP:25(25) Pw:6(6) AC:4 Xp:2/21 Hungry Burdened
Dlvl:1 T:36 Blind Lev
Score is actually right aligned with the edge but I've deleted several
spaces to keep the line shorter here. The status conditions line up
with the hunger slot as that shifts due to changes in gold/HP/power/AC/
experience, and conditions prefer that column even when hunger and/or
encumbrance are blank. Howver, if the number of conditions increase to
the point where they would go off the edge, the whole list shifts left
instead of trying to stay lined up with hunger. (It's just coincidence
that the lefthand parts of lines 2 and 3 seem to line up in this sample.
In general, they don't.)
The vertical layout has reordered most of the fields and now has a few
blank lines to separate those fields into some groups for readability.
Lines have the form of
Field-name : Value
and when highlights apply, now they only affect the value portion.
Single digit characteristics are padded with a leading space so that
all six of them line up (for "18/xx", "/xx" protrudes to the right).
HP and Pw are aligned with each other. Hunger and encumbrance share a
line. When there are more than three conditions, they're shown three
per line instead of wrapping across lines. And if too many lines are
present, it will squeeze out enough blank ones to fit.
To see the vertical status, you need a display size of at least 106
columns with 'windowborders' explicitly off, or 110 with them on; also
set option 'align_status' to 'right' or 'left'. (With borders on,
including the default 'auto' setting, the vertical status appears at
width of 108 columns, but does so by hiding 2 columns of the map; using
110 columns avoids that.) Resizing from outside the game or changing
align_status via 'O' both cause dynamic reconfiguration of the layout;
there's no need to save, make config changes, then restore.
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.
Fixed declarations of draw_classic, draw_vertical and draw_horizontal.
Moved definitions of locals before code. Added initialization of
locals. Changed comments to c-style.
