Be more consistent in the use of path separators.
Add a second version of Makefile variables that contain paths,
one with a trailing separator, and one without (prefixed with R_
for use in Makefile rules).
Also, in dat/luahelper,
Updates due to correspond to the Makefile.nmake changes.
Add Makefile variable AWK to use $(AWK) instead of hardcoded awk.
gcc has recognized various "magic comments" for white-listing
occurrences of implicit fallthrough in switch statements for
a long time:
The range and shape of "falls through" comments accepted are
contingent upon the level of the warning. (The default level is =3.)
-Wimplicit-fallthrough=0 disables the warning altogether.
-Wimplicit-fallthrough=1 treats any kind of comment as a "falls through" comment.
-Wimplicit-fallthrough=2 essentially accepts any comment that contains something
that matches (case insensitively) "falls?[ \t-]*thr(ough|u)" regular expression.
-Wimplicit-fallthrough=3 case sensitively matches a wide range of regular
expressions, listed in the GCC manual. E.g., all of these are accepted:
/* Falls through. */
/* fall-thru */
/* Else falls through. */
/* FALLTHRU */
/* ... falls through ... */
etc.
-Wimplicit-fallthrough=4 also, case sensitively matches a range of regular
expressions but is much more strict than level =3.
-Wimplicit-fallthrough=5 doesn't recognize any comments.
Plenty of other compilers did not recognize the gcc comment convention,
and up until now the compiler warning for detecting unintended
fallthrough had to be suppressed on other compilers. That's because the code
in NetHack has been relying on the gcc approach, and only the gcc approach.
The C23 standard introduces an attribute [[fallthrough]] for the
functionality, when implicit fallthrough warnings have been enabled.
Several popular compilers already support that, or a very similar attribute
style approach, today, even ahead of their C23 support:
C compiler whitelist approach
--------------------------- -------------------------------------
C23 conforming compilers [[fallthrough]]
clang versions supporting
standards prior to
C23 __attribute__((__fallthrough__))
Microsoft Visual Studio
since VS 2022 17.4.
The warning C5262 controls
whether the implict
fallthrough is detected and
warned about with
/std:clatest. [[fallthrough]]
This adds support to NetHack for the attribute approach by inserting a
macro FALLTHROUGH to the existing cases that require white-listing, so
other compilers can analyze things too.
The definition of the FALLTHROUGH macro is controlled in include/tradstdc.h.
The gcc comment approach has also been left in place at this time.
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

Default to INTERNET_AVAILABLE=Y. If the build computer is not
online with the internet available, an explicit
INTERNET_AVAILABLE=N
will be required for the build, if pdcurses and Lua are not already
staged in the lib folder. That can be done by editing the appropriate line
in the Makefile, or by altering the command line:
nmake INTERNET_AVAILABLE=N install
With Makefile.nmake:
Store pdcurses wingui and pdcurses wincon object files in separate
directories.
Rename the two pdcurses static libraries.
Because of the static library changes, the following will be required
prior to the next build:
nmake spotless
