displaying the expected type. Use SCM_LISTn in a couple places
instead of scm_cons-ing by hand.
* __scm.h: Added SCM_ASSERT_TYPE macro.

version of the latter with SCM_ASSERT_TYPE used in
SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)

see ChangeLog entry for 1999-12-28.
GUILE_PROC1. Build guile-procedures.txt, and add that file to
pkgdata_DATA.
* load.c: Added `pkgdata-dir', `site-dir', `library-dir'
primitives.
* guile-doc-snarf.awk: Drop trailing space when no arguments:
e.g., "(foo )" is now "(foo)".
* *.c: moved all the documentation for primitives from
guile-doc/ref/{appendices,posix,scheme}.texi into the source code.
This leaves about half of the primitives undocumented. Also, all
the markup is currently still texinfo. I don't have a problem
with texinfo per se, but the markup is not very descriptive or
accurate.
function headers and argument checking. Switched SCM_PROC,
SCM_PROC1 macros to be GUILE_PROC, GUILE_PROC1 (may change names
later, but was useful to keep old versions around while migrate)
that has docstrings and argument lists embedded in the GUILE_PROC
macro invocations that expand into a function header. Use lots of
new SCM_VALIDATE_* macros to simplify error checking and reduce
tons of redundancy. This is very similar to what I did for Scwm.
Note that none of the extraction of the docstrings, nor software
engineering checks of Scwm is yet added to Guile. I'll work on
that tomorrow, I expect.
* Makefile.am: Added scm_validate.h to modinclude_HEADERS.
* chars.c: Added docstrings for the primitives defined in here.
* snarf.h: Added GUILE_PROC, GUILE_PROC1. Added
SCM_REGISTER_PROC to be like old SCM_PROC, though old SCM_PROC
still remains for now. Changed naming convention for the s_foo
string name of the primitive to be s_scm_foo for ease of use with
the macro.
* scm_validate.h: Lots of new SCM_VALIDATE macros to simplify
argument checking through guile. Maybe some of these should be
folded into the header file for the types they check, but for now
it was easiest to just stick them all in one place.
newline. A bit faster, and definitely hairier.
(scm_read_line): Count newlines here instead.
* strings.c (scm_take_str): New function.
(scm_take0str): Reimplement in terms of scm_take_str. * strings.h
(scm_take_str): New declaration. * ioext.c (scm_read_line): Use
scm_take_str, to avoid copying the string.
Add some simple-minded support for line buffered ports.
* ports.h (SCM_BUFLINE): New flag for ports.
* init.c (scm_init_standard_ports): Request line-buffering on
the standard output port.
* * ports.c (scm_mode_bits): Recognize 'l' as a request for line
buffering.
(scm_putc, scm_puts, scm_lfwrite): If the port is line-buffered,
and there's a newline to be written, flush the port.
* ports.c: (scm_lseek): clear buffers even if just reading current
position.
* fports.c (local_fclose): call local_fflush unconditionally.
(various): don't use the scm_must... memory procs.
* ports.h (scm_port): make read_pos a pointer to const.
strports.c: take care of rw_active and rw_randow.
fports.c: scm_fport_drain_input: removed. do it all in ports.c.
strports.c (scm_mkstrport): check that pos is reasonable.

adjust ptob tables.
* ports.c (scm_ftruncate): new procedure.
fports.c (local_ftrunate), strports.c (str_ftruncate): new procs.
strports.c (st_seek, st_grow_port): new procs.
fports.h (scm_port): change size types from int to off_t.
ports.c (scm_init_ports): initialise the seek symbols here
instead of in ioext.c.
strports.c (scm_call_with_output_string): start with an empty
string, so seek and ftruncate can be used.
* ports.h (scm_ptobfuns): add a read_flush procedure which is the
equivalent to fflush for the read buffer.
* ports.c (scm_newptob): set read_flush.
ports.c (void_port_ptob): set read_flush.
fports.c (local_read_flush): new proc. add to ptob.
strport.c (st_read_flush): likewise.
vport.c (sf_read_flush): likewise.
fports.h (struct scm_fport): remove random member. there's nothing
left but fdes. leaving it as a struct to allow for future changes.
fports.c: replace usage of scm_fport::random with scm_port::rw_random.
ports.c: (scm_putc, scm_puts, scm_lfwrite): call the read_flush
ptob proc if the read buffer is filled.
* ports.h (scm_port): add a rw_random member and replace
reading and writing members with rw_active member.
SCM_PORT_READ/SCM_PORT_WRITE: new values.
* ports.h (struct scm_port_table): add writing and reading members
to replace write_needs_seek: it isn't good enough for non-fports.
ports.c, ioext.c, fports.c: corresponding changes.
(struct scm_port_table): give it a typedef and rename to scm_port.
ports.c, fports.c, strports.c, vports.c, ioext.c, ports.h:
corresponding changes.

* * (scm_lseek): new procedure, using code from ioext.c:scm_fseek
and generalised to all port types.
* scmsigs.c (scm_init_scmsigs): set the SA_RESTART flag for all
signals (it was only being done for handlers installed from Scheme).
Otherwise (for example) SIGSTOP followed by SIGCONT on an interpreter
waiting for input caused an EINTR error from read.
* ports.h (struct scm_port_table): make all the char members
unsigned, so they convert to int without becoming negative if large.
* fports.c (scm_fdes_wait_for_input): forgot to check compilation
with threads enabled. rename this procedure to
fport_wait_for_input and take a port instead of a fdes.
use scm_fport_input_waiting_p instead of scm_fdes_waiting_p.
* readline.c (scm_readline): Applied a patch from Greg Harvey to
get readline support working again: use fdopen to get FILE objects.
* gc.c (scm_init_storage): install an atexit proc to flush the
ports.
(cleanup): the new proc. it sets a global variable which can be
checked by the ptob flush procs to avoid trying to throw
exceptions during exit. not very pleasant but it seems more reliable.
* fports.c (local_fflush): check terminating variable and if set
don't throw exception.
* CHECKME: that the atexit proc is installed if unexec used.
* throw.c (scm_handle_by_message): don't flush all ports here.

and move to ioext.c.
* fports.c (scm_fdes_waiting_p): merged into fport_input_waiting_p.
* ports.c (scm_char_ready_p): check the port buffer and call the
ptob entry if needed.

ptob initialisers. use it in char-ready
* ioext.c (scm_do_read_line): moved from ports.c. make it static.
* vports.c (sfflush): modified to write a char (since softports
currently use shortbuf.)
* fports.c (scm_standard_stream_to_port): moved to init.c and
made static.
* init.c (scm_init_standard_ports): make stdout and stderr
unbuffered if connected to a terminal. with stdio they
were line-buffered by default.
* ports.h (scm_ptobfuns): change fflush return to void.
change flush proc definitions.
* strports.c (scm_call_with_output_string): get size from
buffer instead of port stream.
(scm_strprint_obj): likewise.

* ports.h (struct scm_port_table): added write_end member,
as an optimisation. set it where write_buf_size is set.
* ports.h (struct scm_port_table): change stream from void *
back to SCM. SCM presumably must be large enough to hold a
pointer (and probably vice versa but who knows.)
(SCM_SSTREAM): deleted. change users back to SCM_STREAM.
(scm_puts): rewritten
* fports.c (local_ffwrite, local_fputs): removed.
* strports.c (stputc, stputs, stwrite): dyked out (FIXME)

* fports.h (SCM_MAYBE_DRAIN_INPUT): moved to ports.c.
use ptob for seek. take ptob instead of fport arg.
* ports.h (struct scm_port_table): new member write_needs_seek,
replaces reading member in fport struct.
* vports.c (sfgetc): store the getted char into the buffer.
rename to sf_fill_buffer and install it for fill-buffer in ptob.
the Scheme interface is still a procedure that gets a char.
(scm_make_soft_port): set up the port buffer (shortbuf).
* fports.c (local_fgetc, local_fgets): deleted.
* strports.c (stgetc): likewise.

atexit(). it's too late, errors will cause SEGV.
* fports.c (scm_fport_buffer_add): new procedure.
* fports.h (SCM_FDES_RANDOM_P): new macro. use it in
scm_fdes_to_port and scm_redirect_port.

new port. reset fp->random.
* fports.c (scm_fdes_to_port), ports.c (scm_void_port),

(SCM_FPORTP, SCM_OPFPORTP, SCM_OPINFPORTP, SCM_OPOUTFPORTP): moved
from ports.h.
* genio.c, genio.h: move contents into ports.c, ports.h. The
division wasn't useful.
* fports.c, fports.h (scm_fport_drain_input): new procedure.
* ports.c (scm_drain_input): call scm_fport_drain_input.
* scm_fdes_waiting_p: new procedure.
* fports.c (scm_fdes_to_port): allocate read and/or write buffers.
(scm_input_waiting_p): check the buffer.
(local_fgetc, local_fflush, local_fputc): likewise.
* fports.h (scm_fport): read/write_buf,_pos,_buf_end,,_buf_size:
new members.
* init.c (scm_init_standard_ports): pass fdes instead of FILE *.
* * ports.c (scm_drain_input): new procedure.
ports.h: prototype.
* fports.c (FPORT_READ_SAFE, FPORT_WRITE_SAFE, FPORT_ALL_OKAY,
pre_read, pre_write): removed.
(local_fputc, local_fputs, local_ffwrite): use write, not stdio.
(scm_standard_stream_to_port): change first arg from FILE * to
int fdes.
(local_fflush): flush fdes, not FILE *.
* fports.h (SCM_NOFTELL): removed.
* genio.c, ports.c: don't include filesys.h.
* genio.c (scm_getc): don't use scm_internal_select if FPORT.
do it in fports.c:local_fgetc.
* genio.c: don't use SCM_SYSCALL when calling ptob procedures.
do it where it's needed in the port smobs.
* filesys.c (scm_input_waiting_p): moved to fports.c, stdio
buffer support removed. take SCM arg, not FILE *.
* filesys.h: prototype moved too.
* fports.c (scm_fdes_to_port): new procedure.
(local_fgetc): use read not fgetc.
(local_fclose): use close, not fclose.
(local_fgets): use read, not fgets
* fports.h: prototype for scm_fdes_to_port.
* fports.h (scm_fport): new struct.
* fports.c (scm_open_file): use open, not fopen.
#include fcntl.h
* ports.h (struct scm_port_table): change stream from SCM to void *.
* ports.c (scm_add_to_port_table): check for memory allocation error.
(scm_prinport): remove MSDOS hair.
(scm_void_port): set stream to 0 instead of SCM_BOOL_F.
(scm_close_port): don't throw errors: do it in fports.c.
* configure.in: AC_CHECK_FUNCS: add "system".
* simpos.c (scm_system): always define: use sysmissing if not
available. Check for HAVE_SYSTEM instead of _Windows (does
Windows lack system or does it have an unusable one?).
Check for error conditions -1 and 127. Use SCM_DEFER_INTS.
Let the argument be optional: if not supplied, call system(NULL).
* ports.c (scm_close_port): relax the type check from OPPORTP to
PORTP; closing a closed port is allowed.
* stime.c (tzset): If tzset isn't provided, make it a NOP.
(scm_localtime): Change SCM_EOF to SCM_EOL.
(scm_mktime): Likewise.
* socket.c: Don't include sys/un.h unless autoconf tells
us Unix domain sockets are available.
(scm_fill_sockaddr): Ignore Unix domain code.
(scm_addr_vector): Likewise.
(scm_init_addr_buffer): Likewise.
(scm_socketpair): Don't include unless socketpair was
found during autoconf.
* simpos.c (SYSTNAME): Treat cygwin like Unix.
* scmsigs.c (scm_pause): Don't include unless pause was found
during autoconf.
* posix.c (scm_getgroups): Don't include unless support function
was found during autoconf (in this case, getgroups).
(scm_setpwent): For setpwent.
(scm_setegid): For setegid.
* net_db.c (scm_inet_netof): Don't include unless support
function was found during autoconf (in this case, inet_netof).
(scm_lnaof): For inet_lnaof.
(scm_inet_makeaddr): For inet_makeaddr.
(scm_getnet): For getnetent, getnetbyname, getnetbyaddr.
(scm_getproto): For getprotoent.
(scm_getserv): For getservent.

(scm_setproto): For setprotoent, endprotoent.
(scm_setserv): For setservent, endservent.
* scmconfig.h.in: Regenerated.
