across a hexdigit after having read a # or if not reading a hex
value. This will enable the calling code to correctly handle
forms like 1e2. (The background is, that the exponent markers d,
e and f are also hexdigits.) Thanks to Mikael Djurfeldt for
providing this patch.
(mem2complex): Fix erroneous double-negation. Now, numbers like
1-i will be read correctly.
Initialize. These variables are now registered as gc roots.
(scm_current_pstate): Update documentation.
(scm_current_pstate, scm_make_print_state, scm_free_print_state,
scm_prin1, scm_init_print): print_state_pool is registered as a
gc root and thus does not need to be protected by a surrounding
pair any more.
(make_print_state): The car of print_state_pool no longer holds
the scm_print_state_vtable.
(scm_current_pstate, scm_make_print_state, print_circref,
scm_iprin1, scm_prin1, scm_iprlist): Prefer !SCM_<foo> over
SCM_N<foo>.
(scm_prin1): When building lists, prefer scm_list_<n> over
scm_cons[2]?.
(scm_iprlist): Removed a redundant SCM_IMP test.
(scm_simple_format): Use SCM_EQ_P to compare SCM values.
(scm_memcons, scm_mem_to_proc): When building lists, prefer
scm_list_<n> over scm_cons[2]?.
(scm_mem_to_proc): Prefer SCM_CONSP over SCM_NIMP.
(scm_procedure_name): Use SCM_CADR instead of explicit form.
(debugobj_print): Coerce scm_intprint arg 1 to long, not int.
Thanks to Rob Browning for the patch (see log entry 2001-09-21) -
for some reason his patch didn't make it into the cvs.
is known to be #f if no entry is found. Thus, use !SCM_FALSEP
instead of SCM_NIMP to test for that case.
* strings.h (SCM_SET_STRING_LENGTH): Cast the length to
scm_t_bits instead of long.
whether the integral type fits in a fixnum, not the compiler.
This removes a spurious compiler warning. Also, honor the
NO_PREPRO_MAGIC flag to suppress any preprocessor tests. This is
needed for `long long's.
SCM_T_SIGNED_BITS_MIN): New.
* numbers.h (SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM):
Use them to make these macros computable by the preprocessor.
(coop_create): Set mother_awake_p before creating or signalling
mother; wait until mother is going to sleep before returning.
(mother): Reset mother_awake_p before going to sleep.
protected_objects is now protected from garbage collection using
scm_gc_register_root instead of scm_permanent_object.
(get_option_setting): New static function that computes an option
setting as it was formerly done in the function scm_options.
(get_documented_option_setting): New static function that
returns option documentation as it was formerly done in the
function scm_options. Note that documentation C strings are no
longer precomputed into SCM objects. Instead, they are converted
into SCM strings every time get_documented_option_setting is
called.
(change_option_setting): New static functions that modifies the
option setting as it was formerly done in the function
scm_options. The function is now exception safe, i. e. won't
cause a memory leak when interrupted. Further, only non-immediate
option values are added to the protection list.
(scm_options): This function now has only the purpose to dispatch
to to get_option_setting, get_documented_option_setting or
change_option_setting, depending on the arguments given to
scm_options.
(scm_init_opts): Don't convert documentation C strings into SCM
strings. Further, don't protect any object values: They _must_
be immediate values, otherwise there is no guarantee that they
have not been collected before anyway.
* options.[ch] (scm_t_option): Made type unsigned, name into a
constant char* and val into a scm_t_bits type.
(scm_options, scm_init_opts): The number of options is guaranteed
to be larger or equal to zero. Thus, the type is changed to
unsigned.
non-pair cells.
(SCM_MOST_POSITIVE_FIXNUM, SCM_MOST_NEGATIVE_FIXNUM): Make sure
the return value is signed. Thanks to Brian Crowder for the bug
report.
(SCM_SRS): Avoid unnecessary casting and don't unpack input
values. With this patch, SCM_SRS can be safely used for other
types than scm_t_signed_bits. However, it should still better be
an internal macro and thus be renamed to SCM_I_SRS.
(SCM_MAKINUM, SCM_INUM): Use proper casting.
