Use vi (cursor_invisible) and ve (cursor_normal) to hide and show
cursor, if the terminal supports those. This way on a slower
connection the cursor doesn't jump all over the place when doing
map or menu updates.
Unresolved display issues with rxvt-unicode after the optimizations
dealing with switching between DECgraphics line-drawing character set
and normal character set.
Effectively comment them out rather than revert the commits.
move the custom color data into its own field in the glyphmap
and disassociate it from the unicode/utf8 stuff.
move the glyphcache stuff during options processing and parsing
into new file glyphs.c and out of utf8map.c, and make it
general, and not part of ENHANCED_SYMBOLS.
Do the groundwork for allowing glyph color customizations to
work when any symset is loaded and not restrict it only to
the enhanced1 H_UTF8 symsets.
The customizations in effect are still affiliated with a particular
symset.
Also closes#1224, but the PR itself references a data structure
made obsolete by this commit. The curses comment from the PR was
added into the code.
The PR also made several suggestions, but only the first
one has been included in this commit (and no longer based on
the handler), that being:
"allow defining colors if other symbol handling modes are used
(possibly limited to the standard 16 colors)."
FredrIQ also wrote the following suggestions in PR#1224:
Something I was also contemplating, unrelated to implementation of this
support in curses, would be the ability for the following:
allow defining colors if other symbol handling modes are used (possibly limited to the standard 16 colors)
allow defining attributes (for example: glyph:G_pet_female_kitten:U+0066/red/underline)
allow specifying glyphs as wildcards for defining global color/attribute changes
Something I also want to see are keywords for "don't change the current defined data". If this
were to be added, you could for example do this:
OPTIONS=glyph:G_*_fox:U+0064/blue
OPTIONS=glyph:G_statue_*:basechar/gray/underline
for "make all foxes use a blue color, make all statues gray with underline" without needing
to specify the relevant character for every statue. This ("basechar", "basefg", etc)
should perhaps also be added for MENUCOLORS and statushilites, so that you can, for
example, underline all items being worn without needing to specify a bunch of
near-duplicate rules for combining BUC colors + underline worn items
as per #1064
If a termcap entry for ending attributes and color also contains
the code to switch from secondary font back to primary (HE_resets_AS
hack), maybe strip the AS code out of HE (and clear the HE_resets_AS
flag) when setting up DECgraphics. Affects whether nethack sends
extra AS sequences while rendering a run of VT line-drawing chars.
My HE doesn't reset AS so that aspect hasn't been exercized.
When switching back and forth between normal and line-drawing,
defer the switch away from line-drawing if the character will be
rendered the same in both character sets (uppercase letter, digit,
most punctuation). That might just defer the AE, but could skip it
and next AS depending on what characters are written. The cycle
might repeat an arbitrary number of times, avoiding sending many
AS+AE combinations rather than just one.
Both of these optimizations are pretty small but reducing the number
of characters sent from a server to a remote user is worthwhile.
Make term_start_color() more versatile. If it gets passed NO_COLOR
then it performs term_end_color(). Should be able to streamline
some of the color handling this way although this hasn't done so.
Rest of 'not PR #1102'. Resizing the terminal while getpos was in
operation recalculated the map from scratch instead of redrawing what
the core considers to already be shown. And it was always operating
while an asynchronous signal was excuting which could potentially
clobber whatever was running at the time the signal arrived.
This uses same redrawing as the prior '^R during getpos()' fix. It
also only performs the resize while tty_nhgetch() is waiting for
input. If that is the situation at the time that the signal arrives
then it will resize immediately (while in the asynchronous signal
handler); if not, it will set a flag and tty_nhgetch() will do the
resize the next time it gets called.
This builds with TTY_PERM_INVENT enabled and doesn't seem to be any
worse than before, but there are bugs with that. The only way I could
get perminv to appear was to save and restore, then perm_invent was
honored for both RC file and mO command. And once I managed to get it
to display, moving an item from a lower case slot to slot 'A', made
that item vanish; nothing appeared in the invent's right hand panel.
Both of those misbehaviors already happen prior to this commit. I
also saw an abort+panictrace if I resized while at the "Dump core?"
prompt when running the pre-commit code and didn't see that with the
post-commit code (although the prompt wasn't shown so I couldn't tell
that it was waiting for an answer). The abort probably sounds scarier
than it warrants; I suspect that the pre-commit code just treated the
resize as answering 'y' for some reason, possibly a stale value in the
variable it uses.
My guess about NCURSES_CONST was right; it expands to nothing in the
/usr/include/term.h on my old OSX system. There aren't any levers or
knobs available to avoid that so this adds casts of string literals
to avoid warnings about passing a literal to something that expects
non-const.
There's a lot of conditional code in termcap.c and the nhStr("foo")
(hidden cast) changes only got tested for my default configuraiton.
I tried to avoid typos but I attempt such all the time and we know
how that tends to go.
Are we sure that systems which need to install a curses development
package have term.h without that? A tty-only build shouldn't require
that.
- Move secondary preprocessor defines down further in config.h
so that they can be overridden via [platform]conf.h which is
included from global.h, specifically:
LIVELOGFILE when LIVELOG is defined
DUMPLOG_FILE when DUMPLOG is defined
- Minimize platform-specific, or compiler-specific code in hack.h and decl.h.
- reorganize src/decl.c to align with include/decl.h.
- a new header file cstd.h added, containing calls to C99
standard header files.
- hack.h, decl.h, and decl.c have been cleaned up and had code
moved so that things line up as follows:
hack.h defines values that are available to all
NetHack source files, contains enums for use in all
NetHack source files, and contains a number of
struct definitions for use in all NetHack source files.
It does not contain variable declarations or variable
definitions.
decl.h contains the extern declarations for variables that
are defined in decl.c. These variables are global and
available to all NetHack source files. The location of
the variables within decl.h was random, so give it some
order for now.
decl.c contains the definition of the variables declared in
decl.h, and initializes them where appropriate. The
variable definitions are laid out in much the
same order as their declarations in decl.h.
- wintty.h: There were some varying terminal-related prototypes in
system.h, and that was the only thing left that demanded that
system.h be included. Those have been replaced by an #include
<term.h> in include/wintty.h to get the more current (and hopefully
more correct) prototypes, rather than hardcoding them in NetHack
sources.
For edge-case platform compatiblity, there is no #include <term.h>
if the build defines NO_TERMCAP_HEADERS. In that case one set of
hardcoded prototypes is still used in include/wintty.h.
The added #include "term.h" is also bypassed for NO_TERMS builds (builds
that don't link to terminfo/termcap at all, but still present a tty
interface using platform or window-port specific functions to fulfill
the same role as that of terminfo/termcap).
- some scattered, unnecessary #include "integer.h" were removed from
various files, since that's always included in current NetHack-3.7
sources, either directly from config.h or indirectly from #include
"hack.h".
- system.h references removed.
- new cstd.h added; the #include "system.h" references in Makefiles
and project files (Xcode, visual studio), were replaced
with #include "cstd.h" references. A "make depends" is probably
warranted.
Also:
- Use of <term.h>, which defines clear_screen() as a macro, conflicts
with an actual function with that name in win/tty/termcap.c. The most
straight-forward course of action was to rename the NetHack function,
and change the references to it, from clear_screen() to
term_clear_screen(), so that was done.
Also includes support by paxed for polearm targeting using the
frame color.
Also renames USE_TILES to TILES_IN_GLYPHMAP which is a more
accurate description.
Not all window interfaces have full support for the color framing
of the background square yet.
MS-DOS needs further work (to bring it to both VESA and VGA, with
and without tiles.
Windows GUI is missing support.
X11 and Qt have been started, but may require further refinement.
The consolidation of global variables from scattered source
files into decl.c and declared in decl.h was begun in 3.7.0.
Their placement in common files was done for centralized
initialization and potential re-initialization during a
"play again" scenario.
It wasn't really necessary for all of them to be housed in a
single huge structure to meet the "play again" requirement,
and the single huge structure has been a little unwieldy when
it comes to maintenance.
Following this commit, instead of one single extremely large structure
named 'g' to house all of the relocated global variables, they
are distributed into several ga through gz.
To make things easy for the developer, each variable is placed
into the struct corresponding to the starting letter of the variable.
That way, no lookup is required in order to know which struct houses
a particular variable, it is a simple match to the starting letter
for all the centralized global variables.
A global variable named 'amulets', would be found in ga.
ga.amulets
^ ^
A global varable named 'move', would be found in gm.
gm.moves
^ ^
A global variable named 'val_for_n_or_more' would be found in gv.
gv.val_for_n_or_more
^ ^
A global variable named 'youmonst' would be found in gy.
gy.youmonst
^ ^
A new feature, enabled by default to maximize testing, but one which can
be disabled by commenting it out in config.h
With this, some additional information is added to the glyphmap entries
in a new optional substructure called u with these fields:
ucolor RGB color for use with truecolor terminals/platforms.
A ucolor value of zero means "not set." The actual
rgb value of 0 has the 0x1000000 bit set.
u256coloridx 256 color index value for use with 256 color
terminals, the closest color match to ucolor.
utf8str Custom representation via utf-8 string (can be null).
There is a new symset included in the symbols file, called enhanced1.
Some initial code has been added to parse individual
OPTIONS=glyph:glyphid/R-G-B entries in the config file.
The glyphid can, in theory, either be an individual glyph (G_* glyphid)
for a single glyph, or it can be an existing symbol S_ value
(monster, object, or cmap symbol) to store the custom representation for
all the glyphs that match that symbol.
Examples:
OPTIONS=glyph:G_fountain/U+03A8/0-150-255
(Your platform/terminal font needs to be able to include/display the
character, of course.)
The NetHack core code does parsing and storing the customized
entries, and adding them to the glyphmap data structure.
Any window port can utilize the additional information in the glyphinfo
that is passed to them, once code is added to do so.
Also, consolidate some symbol-related code into symbols.c, and remove it from
files.c and options.c
Redo the tty handling for raw_print_bold() intended to keep it working
after exit_nhwindows(). Don't assign static addresses to nh_HI and
nh_HE in case the routine to free dynamic termcap data somehow gets
called again.
This fixes the broken code that was using a boolean as an integer.
I didn't try to track down when it changed or what it looked like
before the change. The intended effect is fairly straightforward;
just padding a bold line with spaces. I've no idea why someone
deciced that that was useful though.
It also fixes something I broke six years ago: tty_exit_nhwindows()
releases the termcap data needed for turning bold on and off, so
raw_print_bold() used by topten() stopped working on tty then.
Not fixed: the code in really_done() for dealing with topten() vs
the 'toptenwin' option really ought to be redone.
Terminals supporting more than 8 colors can directly display the bright
colors (upper 8 colors of the 16 color palette).
The tty port now only uses bold for displaying bright colors as a fallback to
previous behavior for terminals with 8 colors.
This didn't crash since xputs is defensive and checks if it got a NULL
string, but it also didn't display black entries (dragons, unicorns,
orcish arrows, ...) as black or otherwise different from gray entries.
(strings to switch color) for ANSI_DEFAULT. Instead of lumping
more conditional code into tty_shutdown() I put the new code
into a separate routine and also pulled the existing setup code
out of tty_startup() into a separate routine too.
It will be a miracle if this doesn't break anything due to the
crazy amount of convoluted conditionals present in termcap.c.
On the other hand, I found and fixed a bug while trying to test.
The ANSI_DEFAULT hilites for Gray and No_Color were null instead
of an empty string. MS-DOS stdio apparently fixes that up, but
on OSX (after #undef UNIX and TERMLIB and TERMINFO and #define
ANSI_DEFAULT in termcap.c) I started seeing instances of "(null)"
on the map (OSX stdio does a different fix up for Null pointers)
as soon as I enabled 'color'. It was an attempt to set No_Color.
Closes#411
An Undefined reference to decgraphics_mode_callback was possible
if built for tty only.
drawing.c had an #include "tcap.h" which is what actually defined
TERMLIB. It isn't needed in drawing.c anymore, but it is needed
in symbols.c, in order to get the define for TERMLIB so that
decgraphics_mode_callback variable gets defined.
The undefined reference was from win/tty/termcap.h in code that
was #ifdef TERMLIB, but win/tty/termcap.h has the #include "tcap.h"
Performance profiling showed that multiple strcmpi() calls were
occurring each and every time a character was going to the map.
This update:
- honors the WC_COLOR capability
- It allows a window-port to control individual color availability should the window-port wish to do so.
- Makes checking on the individual colors for the active window-port is a straightforward table lookup at the CLR_ offset.
iflags.use_color remains a master on/off switch for use of color, regardless of the capability
compiled into the game (default TRUE).
The has_color() routine, which is now a shared routine in src/windows.c, could likely be made
into a simple macro to eliminate the function call, but this update does not go that far.
This hits a lot of port files due to the window-port interface change, mostly cookie-cutter.
Another part of github issue 227. Casting a function pointer when
passing it to another function is iffy when lying about the return
type. tputs() expects a routine which returns int, so give it one.
Other xputc() usage is equivalent to putchar(), so define xputc()
with the same function signature as that has.
The tputs() declarations in system.h should probably be changed
(third argument is a function which takes an int rather than
unspecified parameters) but I've left them alone. I made that change
to tputs() in sys/share/tclib.c though.
NT and MSDOS changes are untested. tclib.c compiles ok with clang-
as-gcc on OSX but hasn't been tested with the port that uses it (VMS).
Highlighting via attributes got broken three months ago. May or
may not have been noticeable depending upon which attributes are
supported. Too many variations of attribute designations...
Enable blink and dim for the TERMLIB + !NO_TERMS configuration of the
tty interface. Blink now works the same as in the curses interface
for status highlights. The terminal emulator I'm using has an escape
sequence for dim but it evidently doesn't do anything (same no effect
as with curses), so that isn't adequately tested.
Implement the 'statuslines' option for tty. 2 and 3 line status are
similar to curses. Tty's version doesn't include insertion of extra
spaces for enhanced readability, or ignoring 'showexp' when space is
needed for other fields, or right justifying 'score' and suppressing
it when there isn't room for the entire number. It continues to have
abbreviated condition and encumbrance descriptions that curses lacks
which get used when the normal ones take up too much space.
'statuslines' can be set with 'O' so it is feasible to switch back
and forth between 2 and 3 lines on the fly. But only if the display
is at least 25 lines (actually ROWNO+4) or else CLIPPING is enabled
at build time.
This fixes the bug where after resorting to abbreviated condition
values it sometimes (always?) wouldn't switch back after more room
became available. Abbreviated encumbrance values had problems too
(lack of leading space and not changing value if encumbrance changed
to anything other than unencumbered) and this fixes that as well.
Add code to run a fuzz tester, simulating (more-or-less) random
keyboard mashing. There's no option to turn it on, you need to
set iflags.debug_fuzzer on via a debugger or something along
those lines.
