where calling term_start_color(NO_COLOR) would have the same
effect as calling term_end_color().
That change only included a change for termcap, but not any of
the NO_TERMS configurations. (NO_TERMS is defined for an
implementation where termcap is not used).
This attempts to make sys/msdos/video.c and sys/windows/consoletty.c
honor the change.
The msdos change has not yet been tested.
No attempt was made to alter the term_start_color() implementations
within the outdated tree.
If there were outdated savefiles encountered during
startup, each individual one was getting a wait_synch
that required a <return> even though a message window
wasn't being used at that point.
Allow suppression of the individual per-file wait_synch()
calls on Windows, so that a single one can be done once
the selectsave processing is overwith.
This was a little messy because an indicator had to flow
down through validate(), uptodate(), etc.
There shouldn't be any change in how things behave on
any non-Windows platforms.
- 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 Those have been replaced by an #include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
^ ^
Instead of using index() macro defined to strchr, use C99 strchr.
Instead of using rindex() macro defined to strrchr, use C99 strrchr.
If you want to try building on a platform that doesn't offer those
two functions, these are available:
define NOT_C99 /* to make some non-C99 code available */
define NEED_INDEX /* to define a macro for index() */
define NEED_RINDX /* to define a macro for rindex() */
(user-side decisions really, but as it stands right now
user-side decisions/options are made and processed by the core)
add a parameter to add_menu so color can be passed
Add a rudimentary experimental always-up inventory display
capability to tty when the perm_invent option is in effect.
It requires an additional 28 rows available on the terminal
underneath the bottom status line.
It hasn't been optimized for performance as of yet.
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
Incorporate the functionality of the loadable DLL's (nhraykey.dll,
nhdefkey.dll, and nh340key.dll) into the consoletty.c code and
remove the dll building
Microsoft has been making a recommendation that programs should switch
from using the classic low-level console API calls to virtual terminal
sequences for a couple of years.
References:
"Our recommendation is to replace the classic Windows Console API with virtual
terminal sequences. This article will outline the difference between the two
and discuss the reasons for our recommendation."
From:
Classic Console APIs versus Virtual Terminal Sequences
https://docs.microsoft.com/en-us/windows/console/classic-vs-vt
The online documentation for WriteConsoleOutputCharacter() and
WriteConsoleOutputAttribute() have this disclaimer on them:
"This document describes console platform functionality that is no longer a
part of our ecosystem roadmap. We do not recommend using this content in new
products, but we will continue to support existing usages for the indefinite
future. Our preferred modern solution focuses on virtual terminal sequences
for maximum compatibility in cross-platform scenarios. You can find more
information about this design decision in our classic console vs. virtual
terminal document."
Since NetHack started out as a terminal program, before there was a
Windows "classic" console API introduced with Windows NT, it seemed only
fitting that the Windows console port should evolve in the virtual terminal
direction.
This is a first stab at it. The performance won't be as instantaneous as
the low-level console API's. That's likely partly because of this consoletty.c
initial implementation, but it may also partly be because under the hood in
the OS, there's recognitions/translations/conversions going on. Microsoft
states it will continue to evolve the Windows Terminal and console, and
hopefully it will improve. Hopefully it isn't too slow to play. It still
attempts to take advantage of the back buffer stuff that Barton House
introduced to minimize screen updates. At this point, it can still be
recompiled without the virtual terminal support by defining NO_VT when
compiling consoletty.c, or by commenting out the definition of
VIRTUAL_TERMINAL_SEQUENCES at the top of sys/windows/consoletty.c
That's the informational news, and the negative news out of the way.
There's some good news too. Because the virtual terminal sequences
support include 24-bit color support, the Windows console under virtual
terminal sequence can provide a more pleasant set of colors to the NetHack
console interface. To that end, some color changes have been implemented
in consoletty.c now.
It makes the console port ready to accept and display 24-bit color from
the NetHack core, if that should ever happen, as well.
As usual with a first implementation, there may be some bugs. Reports
are welcome.
rename sys/winnt to sys/windows
move vs (visual studio) folder out of win/win32 and into sys/windows
rename include/ntconf.h to include/windconf.h
rename winnt.c to windsys.c
place visual studio projects into individual subfolders.
This will hopefully resolve GitHub issue #484 as well.
