before iterating over it. The table might change while the user
code is running. With the snapshot, the user can depend on the
fact that each port that was open at teh start of the iteration is
encountered exactly once. (ice-9 popen) depends on this.
read-string!/partial.
* ports.c (scm_take_from_input_buffers): new procedure used by
scm_read_string_x_partial.
(scm_drain_input): use scm_take_from_input_buffers.
* ports.c (scm_port_for_each): new proc. implements port-for-each,
which applies a procedure to each port in the port table.
ports.h: declare scm_port_for_each.
* ioext.c (scm_dup2): new proc. implements "dup2" which is a simple
wrapper for the dup2 system call (unlike dup->fdes or
primitive-move->fdes).
* ioext.h: declare scm_dup2.
* filesys.c (scm_close_fdes): new proc. implements "close-fdes"
which is a simple wrapper for close system call (unlike scm_close).
* filesys.h: declare for scm_close_fdes.
* Fix some string/symbol output problems with regards to substrings.
* Fix error output to prefer procedure name parameters over stack data.
* Use SCM_(SET_)?FILENAME where appropriate.
* Prefer calling scm_remember over scm_protect/unprotect_object calls.
and we don't want that.
(INCLUDES): Removed all -I options except for the root source
directory and the root build directory.
* *.*: Change includes so that they always use the "prefixes"
libguile/, qt/, guile-readline/, or libltdl/.
(Thanks to Tim Mooney.)
(end_input_void_port): renamed to end_input_default.
* init.c (scm_standard_stream_to_port): create a void port instead
of opening /dev/null if the standard file descriptors are bad.
advantages: no portability problems, doesn't waste a file descriptor,
simplifies the code (thanks to Marius for the idea).
* vports.c (s_scm_make_soft_port): call scm_port_non_buffer.
* void ports: make reading from a void port give EOF instead of
segv:
* ports.c (s_scm_sys_make_void_port): modified docstring.
(fill_input_void_port): new proc.
(scm_init_ports): set up fill_input_void_port.
* ports.c (scm_port_non_buffer): new proc.
(scm_void_port): call scm_port_non_buffer.
* fports.c (scm_setvbuf): docstring: remove the fcntl documentation
which was incorrectly appended.
name for a Scheme object (now a void*), and SCM as 32 bit word for
storing tags and immediates (now a long int). Introduced
SCM_ASWORD and SCM_ASSCM for conversion. Fixed various dubious
code in the process: arbiter.c (use macros), unif.c (scm_array_p),
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.
* validate.h, scm_validate.h: Added the former, as a renamed
version of the latter with SCM_ASSERT_TYPE used in
SCM_MAKE_VALIDATE (instead of just SCM_ASSERT)
* Makefile.am: Rename scm_validate.h to validate.h.
* *.c, *.h: Include validate.h, not scm_validate.h (old name's
prefix was superfluous).
added append docs from R4RS.
* strings.c: Docstring typo fix, + eliminate unneeded IMP tests.
Thanks Dirk Hermann!
* chars.h: Provide SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR and
deprecate SCM_ICHRP, SCM_ICHR, SCM_MAKICHR. Thanks Dirk Hermann!
* *.h, *.c: Use SCM_CHARP, SCM_CHAR, SCM_MAKE_CHAR throughout.
Drop use of SCM_P for function prototypes... assume an ANSI C
compiler. Thanks Dirk Hermann!
return SCM_UNSPECIFIED instead of a (not-scheme-object) integer
that caused a seg fault. Also fixed `set-port-column!'s
docstring. Thanks Han-Wen Nienhuys for finding the bug!
regex-posix.c, scmsigs.c, stime.c, strings.c, variable.c, stime.c,
strings.c, variable.c: Added lots of documentation, cleaned up
some existing documentation. Occasionally changed formal params
to match docs. Also folded an #ifdef into the inners of a
primitive instead of having two copies of the primitive
(`get-internal-real-time', from stime.c)
* error.c, gh_data.c, ports.c, script.c, strop.c: include <string.h>.
* strings.c (scm_string_ref): make the 2nd argument compulsory.
previously it defaulted to zero for no good reason that I can see.
use a local variable for SCM_INUM (k). replace
SCM_VALIDATE_INUM_DEF with SCM_VALIDATE_INUM_COPY.
(scm_makfromstr): cosmetic changes.
(scm_string): Accept only chars in the list, not strings, for
conformance to R5RS (particularly for list->string, which is
supposed to be the inverse of string->list.) remove
SCM_DEFER_INTS/SCM_ALLOW_INTS, which is unnecessary since
scm_makstr handles the cell allocation. when reporting wrong-type
arg, don't report the position as 1.
* posix.c (scm_init_posix): intern PIPE_BUF if it's defined.
* boot-9.scm (find-and-link-dynamic-module): pass strings, not symbols,
to string-append.
SCM_OUT_OF_RANGE use SCM_MAKINUM, not scm_long2num. Added
SCM_COERCE_ROSTRING macro. Added SCM_VALIDATE_NONEMPTYLIST
macro. Fix SCM_VALIDATE_STRINGORSUBSTR macro to not use SLOPPY
variants.
* ports.c (scm_port_closed_p): Validate that the arg is a PORT,
then return whether it's an open port (was validating that it was
an open port -- this was a bug I introduced back in December, but
my careful reading of diffs caught it).
* numbers.c: Recombine the two conditional-compilation paths for
all the log* primitives -- they were split based on #ifndef
scm_long2num; factored out a SCM_LOGOP_RETURN macro, and fixed
some bugs and inconsistencies in the two sets of implementations.
(scm_lognot) Fixed *atrocious* re-use of a SCM as an integer!
* ioext.c: Use SCM_ASSERT_RANGE in a couple places, and
SCM_VALIDATE_INUM_COPY once where it should've been used.
* fluids.c (scm_internal_with_fluids): Use
SCM_VALIDATE_LIST_COPYLEN.
* filesys.c: Use SCM_NUM2LONG instead of SCM_VALIDATE_INUM_COPY;
this is questionable as it relaxes type safety, but other changes
were useful and all SCM_NUM2LONG's should probably be
revisited. Use SCM_OUT_OF_RANGE, SCM_WRONG_TYPE_ARG.
* evalext.c: line-break change on 1 line.
* eval.c (nconc2last): Takes a non-empty list as its first
argument, not just a list.
* dynl.c: Use new SCM_COERCE_ROSTRING macro.
strop.c: Use SCM_VALIDATE_ICHR, SCM_VALIDATE_ICHR_COPY instead of
SCM_VALIDATE_CHAR, SCM_VALIDATE_CHAR_COPY. Change made for
consistency with the other macros dealing with immediate
characters. (Similar to INT -> INUM change a week or so ago).
net_db.c, read.c, socket.c: Update error messages to use ~A for
%s, ~S for %S to work with new `simple-format' format and be
standardized better.
* print.h, print.c (scm_simple_format): Added `simple-format'
primitive. It's the old scm_display_error, with ARGS now a rest
parameter, and the destination first instead of last (and a couple
new capabilities inspired by `format' -- #t as destination means
current-output-port, #f means return the formatted text as a
string.
* gh.h, gh_data.c, ports.h, ports.c: Added some missing const specifications.
* backtrace.c (scm_display_error_message): Rewrote to use
scm_simple_format() procedure.
* __scm.h: Added commented-out #define of GUILE_DEBUG_FREELIST
