arguments, don't set the car of (command-line) to scm_usage_name,
the prettified name of the guile executable; give it the full
path, the way shells usually handle $0.
makefile variable as a build parameter called LIBS. The
build-guile program will use this, for the time being.
* Makefile.in: Regenerated.
* Makefile.in: Regenerated with automake 1.2a.
`display-error' and `display-backtrace' so that error reporting
won't get into infinite loops if an error occurs during displaying
of the error. This can very easily happen with user supplied
print call-back routines.
Added #include "objects.h"
* eval.c (scm_makprom): Added SCM_DEFER_INTS and SCM_ALLOW_INTS.
Add #include "feature.h".
* ports.h (SCM_EOF_OBJECT_P): New macro predicate.
This test is needed at many places in the code and should be
abstracted. (Motivated by the need of this test in libguiletk.)
* ports.c (scm_eof_object_p), vports.c (sfgetc), strports.c
(scm_eval_string), load.c (scm_primitive_load,
scm_read_and_eval_x), gh_eval.c (gh_eval_str):
Use SCM_EOF_OBJECT_P.
* eval.c (scm_init_eval): Add feature `delay'.
* gsubr.c: New global symbol scm_i_inner_name.
* debug.c (scm_procedure_name): Try procedure property
`inner-name' if `name' fails.
* print.c (scm_iprin1): Use scm_macro_name.
* eval.c (scm_m_define): Give names to macros as well; Only the
first top-level definition gives a procedure/macro a name.
Otherwise confusing names can turn up in backtraces.
(SCM_CEVAL): SCM_IM_DEFINE: Set `inner-name' property instead of
`name'; Give names to macros as well.
* procs.c (scm_closure_p), print.c (scm_iprin1), eval.c
(scm_macro_transformer): Use SCM_CLOSUREP instead of
scm_closure_p.
procedures;
(prinmacro): Removed. The code has been moved/merged into print.c
in order to decrease code redundancy. We want macros to print in
a way equivalent to procedures, and it would be silly to duplicate
the required code. (We don't want to maintain two places.)
(macrosmob): Print field is now a NULL pointer.
* eval.h (scm_macro_p, scm_macro_type, scm_macro_name,
scm_macro_transformer): New prototypes.
(scm_tc16_macro): Declared.
* * print.c (scm_iprin1): Added code for printing of macros. Macros
are now printed in a way equivalent to procedures.
gh_vector_p, gh_pair_p, gh_number_p, gh_string_p, gh_procedure_p,
gh_list_p, gh_inexact_p, gh_exact_p, gh_eq_p, gh_eqv_p,
gh_equal_p): Use SCM_NFALSEP, instead of testing against
SCM_BOOL_T. Any non-false value is true.
scm_gensym): Added prototypes.
* symbols.c (scm_gensym): New function. This will speed up
certain types of applications (such as macro systems) which
generate lots of symbols.
* stime.c (scm_times): new procedure.
* ioext.c (scm_fseek): if the first argument is a file descriptor
call lseek.
(scm_ftell): if the first argument is a file descriptor call lseek
(sic).
* filesys.h: prototypes for scm_open_fdes, scm_fsync.
* filesys.c (scm_chmod): if the first argument is a file descriptor,
call fchmod.
(scm_chown): if the first argument is a port or file descriptor,
call fchown.
(scm_truncate_file): new procedure.
Add DEFER/ALLOW INTS to a few other procedures.
(scm_fsync): new procedure.
(scm_open_fdes): new procedure.
(scm_open): use scm_open_fdes. If mode isn't specified, 666 will
now be used.
(scm_fcntl): the first argument can now be a file descriptor. The
third argument is now optional.
* posix.c (scm_execl, scm_execlp): make the filename argument
compulsory, since omitting it causes SEGV.
(scm_sync): return unspecified instead of #f.
(scm_execle): new procedure.
(environ_list_to_c): new procedure.
(scm_environ): use environ_list_to_c. disable interrupts.
(scm_convert_exec_args): take pos and subr arguments and
improve error checking.
* boot-9.scm: define tms accessors: clock, utime, stime, cutime,
cstime.
(scm_call_with_new_thread): Bugfix: SCM_WNA should go as third
argument to SCM_ASSERT. Furthermore, the name of the function
should be passed as first argument when signalling
SCM_WNA. (Thanks to Thomas Morgan)
<shouman@zianet.com>: "The switch in scm_gsubr_apply that
dispatches on the number of actual args has a default case
reporting an internal error. This is a vestige from a version
that mallocated a SCM vector to hold the arguments. In the
current version this check is too late: if it ever happens we will
have already overstepped the bounds of the array.
Also, the patch [...] adds a check for too many actual arguments."
mdj: Removed check for "internal programming error".
throw.c (scm_internal_stack_catch): New sibling to the other catch
functions. Code moved from gh_eval.c.
throw.h: Added header.
gh_eval.c (gh_eval_str_with_stack_saving_handler): Renamed call to
scm_internal_stack_catch.
* ioext.c (scm_dup_to_fdes): renamed from scm_primitive_dup2.
Scheme name is now dup->fdes.
(scm_dup_to_fdes): make the second argument optional and
fold in the functionality of scm_primitive_dup.
(scm_primitive_dup): deleted.
* fports.h (SCM_P): prototypes for scm_setvbuf, scm_setfileno.
* fports.c (scm_setbuf0): don't disable the setbuf if MSDOS or
ultrix are defined. Use setvbuf instead of setbuf.
(scm_setvbuf): new procedure.
(scm_init_fports): intern _IOFBF, _IOLBF, _IONBF.
(scm_setfileno): moved from ioext.c.
(scm_fgets): cast SCM_STREAM to (FILE *), remove unused lp variable.
(top of file): Delete 25 lines of probably obsolete CPP hair for MSDOS.
* boot-9.scm (move->fdes, dup->port): use dup->fdes, not primitive-dup.
(dup->fdes): deleted, now done in C.
state as nested data while they are printed.
(print_state_fluid, print_state_fluid_num): New variables.
(scm_init_print): Initialize them.
(scm_iprin): If print_state_fluid carries a print_state, use that
instead of creating a new one.
(scm_printer_apply, apply_stub, struct apply_data): New
definitions to help with calling printer functions written in
Scheme.
* print.h (scm_printer_apply): New prototype.
