When dgn_comp.l and lev_comp.l are processed by older versions of
flex, 'gcc -Wunused' complains when compiling dgn_lex.c and lev_lex.c
because flex creates 'static void yyunput()' and nethack doesn't use
it. Newer versions honor macro YY_NO_UNPUT to hide the offending
code, but that doesn't help with older versions (like the one
masquerading as 'lex' on OSX). Adding a dummy usage would probably
cause problems with other lexers, so change it from static to
'void yyunput()' as a 'sed' fixup in util/Makefile after flex has
finished. That will be a no-op when yyunput doesn't exist or isn't
static.
In addition to the sys/unix/Makefile.utl change, this checks in new
sys/share/{dgn,lev}_lex.c with the fixup in place.

github pull request #19 made reference to resulting code behaviour
being better when windows were resized when USE_WIN_IOCTL was defined.
The logic for including the necessary enabling code in the build in
sys/share/ioctl.c was an explicit "opt-in" strategy, so anything not
deliberately and explicitly listed was not able to take advantae
of the potentially useful code. The need to add #defines to that
list would have been perpetual as new platforms came online, and
unnecessarily restrictive for everything else.
This switches the logic to include the code by default now,
and thus
unless there is an explicit "opt-out" by uncommenting
AVOID_WIN_IOCTL in include/unixconf.h
Some platforms, and we have no way of knowing which ones, may have
to ensure that AVOID_WIN_IOCTL is #define'd.
Incorporate some git information into NetHack so that it
is potentially visible to a player. That's useful when
collecting details about the version that they are
running and, if the gitinfo is present, it can tie the
code to a specific git commit in the repository.
This modifies 'makedefs -v' to check for the presence of a data file
called dat/gitinfo.txt and if it is there, parse out its
contents, then write additional lines to include/date.h beyond
what 'makedefs -v' was previously putting in there, similar to
this sample:
#define NETHACK_GIT_SHA "0c84e564c78e2024e562d39539376ce2e21eec8e"
#define NETHACK_GIT_BRANCH "NetHack-3.6.0"
The contents of an appropriate dat/gitinfo.txt are as follows,
and trailing/leading whitespace is not significant:
githash = 0c84e564c78e2024e562d39539376ce2e21eec8e
gitbranch = NetHack-3.6.0
It also adjusts the contents of the 'v' version information to
include the additional git info when available.
Also adds some hooks DEVEL/hooksdir and a perl file to DEVEL
for simplifying and automating the deposit of dat/gitinfo.txt
so that it generally reflects the most current git commit.
DEVEL/gitinfo.pl can be used to build dat/gitinfo.txt at any
time without doing a commit, merge, or checkout.
perl DEVEL/gitinfo.pl
command line --version and -version support
To complement the extra information being provided in the
version by the 'v' command, this also adds support for the
following new command line arguments:
--version
-version Output the NetHack version string then exit.
--version:paste Output the NetHack version string and also copy it to
-version:paste the platform's paste buffer for insertion somewhere,
then exit.
If the paste variation of -version is requested on a platform that
hasn't incorporated any support for the capability, it will deliver
the version info then an error message, prior to exiting.
To support the extended -version:paste variation, a port needs to:
- provide a port-specific routine to perform
the paste buffer copy in a port code file.
- #define RUNTIME_PASTEBUF_SUPPORT in the include/portconf.h header file.
--skeleton--
void port_insert_pastebuf(buf)
char *buf;
{
/* insert code to copy the version info from buf into
platform's paste buffer in a supported way */
}
macosx and Windows have both added support for RUNTIME_PASTEBUF_SUPPORT
Defined strbuf_t and related routines to support dynamically sized
strings. Modified strip_newline() to strip the last newline in a string
instead of the first.
Simplified splash window code using new strbuf_t.
Prior to exiting game, re-enable getreturn and call wait_synch() in
case there is buffered raw prints that must be displayed to user.
If user can make NETHACKOPTIONS point to a file, that user could then
get the file contents via the extended config file error reporting.
Add CONFIG_ERROR_SECURE compile-time option to make that case output
only the first error, no line number or error context.
This is from the pull request for the assertion failure fix. It
did not mention how to reproduce the assertion failure, just added
casts to a bunch of isspace/isprint/tolower calls that didn't already
have such.
I removed an obsolete change for win/tty/topl.c and changed the
win/win32/mswproc.c code to avoid using an expression with side-effects
(*colorstring++) in calls to tolower() in case someone overrides that
with a macro which evaluates its argument more than once as some pre-
ANSI ones used to do. Not tested, might have typos....
sys/wince/*.c still needs similar casts.
Since the attempted fix for the warning about has_color() being
implicitly declared introduced a worse problem of conflicting
declaration in cases where it's already declared, back that change
out.
Increase the lex paramaters in lev_comp.l and replace use of snprintf
with sprintf in lev_comp.y and lev_main.c.
Also some reformatting for lev_comp.y, but I gave up pretty quickly:
some early tab replacement and adjusting of the spacing for casts.

Related to #H4170, bz274
The current startup code seeks out the SYSCONFPREFIX using:
envp = nh_getenv("COMMONPROGRAMFILES");
which is fine and usually translates to something like
"C:\\Program Files (x86)\\Common Files\\
NetHack then tacks on the NetHack subfolder to the path
"C:\\Program Files (x86)\\Common Files\\NetHack\\"
That should always be the definitive location.
However, in the event that there is no SYSCF_FILE actually
located at that system-wide spot (and ONLY in that event),
fall back to a secondary location of HACKDIR for locating
the SYSCF_FILE.
Also, there's some explicit tweaking added for the Microsoft
visual studio compiler debug execution to all a debug
session to correctly locate things. By default, on a
visual studio build, the executables are linked down in
subfolders of the build directory (Release, or Debug,
depending on visual studio build configuration options).
_M_UNIX (SCO UNIX) and __linux__ (all flavors of linux?) both call
has_colors() for TTY_GRAPHICS+TEXTCOLOR configuration, but neither
declared it. The new declaration is just a guess based on usage.

Bug 123 Report 4030:
Minor thing I've noticed - if I quit the game, at the "Hit <Enter> to end."
prompt, if I close the window rather than pressing Enter, I get the following:
Bug 138 - #H4045:
"nethack -s" leads to "-s is not supported for the Graphical Interface".
That's wrong.
(The Graphical Interface comes with "nethackw".)
The HP C compiler for VMS issued a pair of diagnostics for both *_lex.c
files, about an expression of the form (unsigned_var <= 0) maybe not
being what was really intended, and it was right. Changing that to
'< 1' would have suppressed the diagnostic but left the bug, which was
in code that performed a subtraction and then checked for a negative
result. It worked in older flex versions when the variables were
signed, but got broken when they were changed to unsigned (no doubt in
respose to gcc complaining about comparing signed and unsigned in some
other spot where one of them was used).
The bug is in flex's original skeleton, so was inherited by our new
custom skeleton. I've fixed it in the custom skeleton, which means
that sys/share/*_lex.c became out of date even though util/*_comp.l
remain unchanged.
Generated with flex 2.6.0 and a new custom skeleton for that version
(which almost certainly won't work with any older or newer version of
flex, but that limitation has no effect on the usefulness of the
generated scanner code).
Function definitions are oldstyle:
int foo(bar)
char *bar;
{...}
rather than ANSI, like nethack's core code. Advance declarations use
FDECL for prototypes, so should also fit nethack, although the usage
'FDECL(, (arglist))' makes me feel a bit uneasy. gcc doesn't mind the
omitted first argument but other compilers might not like it.
The system headers (stdlib.h and a few others) that flex has been
insisting on including are gone (with this skeleton). It starts out
including "config.h" and that header has the responsibility for any
definitions and declarations necessary. That shouldn't be a big deal
since config.h -> XXXconf.h -> system.h is what we're already relying
on for everything else, but it does need testing for any configuration
that uses sys/share/{dgn,lev}_{lex,yacc}.c.
I'll be checking the skeleton into the NHinternals repository after
adding some documentation, but I'm wondering whether it should really
become part of the source distribution.
I started out cleaning up a bit of lint in the recent run-time options
handling and discovered that pmatchregex wasn't finished. Finish it and
also deal with the version lint. Argument declarations for function
definitions in pmatchregex.c have been switched to K&R style. (The ones
in posixregex.c have been left in ANSI style.)
There wasn't any build rule for pmatchregex.o; now there is (for Unix).
posixregex.o is still the default.
There isn't any build rule for cppregex.o (again, for Unix); the change
to cppregex.cpp is untested.

Some options in 3.6.0 are determined by what you link with.
The choice of regex support is one.
Let #version show that linked option along with the compile-time options.
I did my best to exempt some of the bigger aligned blocks from the reformatting
using the /* clang-format off */ and /* clang-format on */ tags. Probably some
that shouldn't have been formatted were anyway; if you encounter them, please
fix.
The clang-format tags were left in on the basis that it's much easier to prune
those out later than to put them back in, and it means that, modulo my custom
version of clang-format, I should be able to run clang-format on the source tree
again without changing anything, now that Pat has fixed the VA_DECL issues.
Make the variadic functions look more like ordinary code rather than
have the function opening brace be hidden inside the VA_DECL() macro.
That brace is still there, but VA_DECL() now needs to be followed by
a visible brace (which introduces a nested block rather than the
start of the funciton). VA_END() now provides a hidden closing brace
to end the nested block, and the existing closing brace still matches
the one in VA_DECL().
Sample usage:
void foo VA_DECL(int, arg) --macro expansion has a hidden opening brace
{ --new, explicit opening brace (actually introduces a nested block)
VA_START(bar);
...code for foo...
VA_END(); --expansion now provides a closing brace for the nested block
} --existing closing brace, still pairs with the hidden one in VA_DECL()
This should help if/when another round of reformatting ever takes place,
and also with editors or other tools that do brace/bracket/parenthesis
matching.
I had forgotten that there were variadic functions in sys/* and ended
up modifying a lot more files than intended. The majority of changes
to those just inserted a new '{' line so that revised VA_END()'s '}'
won't introduce a syntax error. A couple of them needed VA_END() moved
so that local variables wouldn't go out of scope too soon. Only the
Unix ones have been tested.
I'll push a formatting guide at some point. There may still be
outstanding changes, but please feel free to resolve those as you arrive
a them.
To the best of my knowledge, there is no changes to the actual code
content, but the formatter does have the occasional bug. If you run into
an issue, please fix it!

Adjust the code and the command line Makefile so that
you no longer have to choose whether to build the tty
version NetHack.exe, or the gui version NetHackW.exe.
Both will now be built in a single 'nmake install' pass.
