I'm not sure whether basic formatting cleanup belongs in 3.6.1, but
there are also a couple of strings that got split and require the
implicit concatenation of adjacent string literals introduced with
C89/C90. The code itself compiles with pre-ANSI compilers, or at
least used to--most of it was developed with one....
Much of it is tabs in comments. But there was one substantive item:
an obsolete reference to "use 'Q' to Quit" after however many years....
This is important for public servers. Setting the MAXPLAYERS
sysconf value to 0 (or commenting it out) constructs the lock
files with the player UID and player name, so each player may
have one game at a time.
Some commented make variables for X11 misspelled 'pilemark.xbm' with
bad '.xbm' suffix.
'symbols' was handled strangely, but it still should have been working
during playground installation. This removes the strangeness but I have
no idea whether it solves #H4015 ('unable to access "symbols" file' for
the Mac OSX binary).
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that sys/share/*_lex.c became out of date even though util/*_comp.l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.
SYSCF is enabled by default, but nethack won't run without the required
sysconf file. sys/vms/install.com expects to find a template one in
sys/vms/sysconf so create that.
Since the tarball will need repackaging, fix a comment typo (dyslexic
spelling of "nymph") in sys/unix/sysconf. Also, move DEBUGFILES to the
bottom so that more useful entries move up. And expand the comment for
the PANICTRACE options.
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.
This could use a bit of reformatting. I stripped off trailing spaces
from a handful of lines but otherwise have kept it as is since the
formatting issue is minor.
Change the 'make' rules for *_lex.c, *_yacc.c, and *_comp.h to put
the end files names into whatever #line directives that refer to
the generated names (lex.yy.c, y.tab.c, y.tab.h). This should not
produce any change in behavior during compilation except to provide
more accurate specifications of where any warnings or errors occur.
Add a 'make dist' target that copies generated scanner and parser
files to sys/share. (As mentioned in the previous patch, I haven't
committed any of those since I have different versions of flex and
also of bison.)
Changes to be committed:
modified: sys/winnt/Makefile.msc
I've noticed odd output from some of the echo statements
used in the Microsoft nmake Makefile before, but never
bothered to investigate why.
Pat observed that it was due to conversion of \t
in the path that resulted from expansion of the target
macro $@
This change uses the macro character substitution
feature to convert the back slashes to forward slashes
in the message, making the quirky conversion go away.
Add missing 'sysconf' to sys/unix/ and sys/winnt/ sections of Files.
Update sys/unix/sysconf; I started out just to remove the duplicate
DEBUGFILES entry but ended up expanding several of the comments too.
Also, fix a typo in the vms build/install instructions.
Update the unix Makefiles and the older OSX hints files to handle the
pile marker tile overlay. I didn't touch hints/macosx10.10 and .11
since I think there's still a merge for them pending.
A couple of formatting tweaks for bemain.c are included, for no
compelling reason. What are the odds that anyone will every build
that again?
Confusing build failure, explained by a typo in sys/unix/Makefile.utl.
dgn_lex.o didn't get rebuilt after modifying unixconf.h to take out
the #define MONITOR_HEAP I had in place, resulting in link failure for
dgn_comp because the old object file was referencing 'nhalloc' rather
than 'alloc'. dgn_lex.o accidentally didn't care about modifications
to config.h and the other headers that pulls in, such as unixconf.h.
This typo was already present when the last cvs repository was
initialized nearly 14 years ago.
dungeon.o depending on lev.h is the only change found by 'make depend'.
(I'm a bit suspicious about that.)
I haven't attempted to reconcile the vms Makefiles with the Unix ones,
just put in this one new dependency. I know vms/Makefile.src lacks
handling for sys/share/*regex.c and vms/Makefile.top and install.com
both lack handling for 'sysconf'.
README - add VMS back as a tested platform; thanks KevinS!
dat/history - add VMS update, remove trailing whitespace, two spaces;
instead of just one (recently added stuff) for sentence separation;
sys/vms/Install.vms - minimal update;
Files - reformat the win32 project section to fit within 80 columns.
Update the command procedure that can be used to compile and link
everything. The sys/vms Makefiles still need updating.
I added 'tribute' to the command procedure used to create and populate
the plaground directory but am not able to test it.
This makes installing NetHack on a public server much easier.
Required some minor changes to the unix top-level Makefile, and
the other hints files; Makefile variable HACKDIR may not be a
full path anymore, use INSTDIR instead.
