+
+ * numbers.c (scm_logand, scm_logior, scm_logxor, scm_logtest,
+ scm_logbit_p): Do the computation in ulongs. This is not as nice
+ as doing it in bignums, but at least it's good enough for
+ manipulating flags in 32-bit words. (Thanks to Jim Wilson.)
+
+ * regex-posix.c (scm_regexp_exec): Reliably mark unmatched

+1998-11-23 Mikael Djurfeldt <mdj@kenneth>
+
+ * feature.c, feature.h (scm_make_hook, scm_add_hook_x,
+ scm_remove_hook_x, scm_run_hooks): Moved from ice-9/boot-9.scm.
+ (scm_make_named_hook): New function.
+
+ * feature.c: Added #include "eval.h".
+
+ * modules.c (scm_make_module): Beautify the module.
+
+1998-11-22 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
+
+ * modules.c, modules.h: New files: C interface to modules. (This
+ is necessary in order to interface the object system to Guile
+ properly. The guts of these modules will be replaced by the new
+ module system in the future.)
+
+ * init.c: Added #include "modules.h"
+ (scm_boot_guile_1): Call scm_init_modules.

+
+ * procs.c: #include "objects.h"
+ (scm_procedure_p): Return #t also on structs which are operators.
+
+ * objects.c (scm_init_objects): Renamed <standard-metaclass>,
+ <operator-metaclass> and <entity-class> to <standard-class>,
+ <operator-class> and <entity> in order to conform with STKlos
+ naming conventions.
+
+ * eval.c (SCM_CEVAL): Jump to badfun if trying to apply a struct
+ which isn't an operator.
+ (SCM_APPLY): Ditto, but jump to badproc.
+
+1998-11-21 Mikael Djurfeldt <mdj@kenneth>
+
+ * eval.c (SCM_CEVAL): Allow structs implanted in code.
+ Previously, structs implanted in code were interpreted as forms
+ the operator of which was a gloc. We solve this by checking for
+ the zero in the emulated vcell in the struct vtable. Since
+ implanted structs always will look like forms with a gloc
+ operator, execution will only be slowed down by maximally one
+ extra test-and-branch per application.
+
+ * evalext.c (scm_definedp): Removed check for isyms; Added a
+ second optional argument: It is now possible to supply an
+ evaluation environment in which to look for the symbol.

+
+ * coop.c (coop_condition_variable_wait): Removed
+ (coop_condition_variable_wait_mutex): Folded logic of
+ coop_mutex_unlock into coop_condition_variable_wait_mutex to
+ prevent condvar signal lossage. Previously, another thread could
+ start to run after unlocking the mutex but before putting the
+ current thread on the wait queue. If that thread then would
+ signal the first, the signal would be lost. (Thanks to Christian
+ Lynbech.)

+

+
+ * debug.h (SCM_MACROFRAME, SCM_MACROFRAMEP): New frame type.
+
+ * eval.c (SCM_CEVAL): Mark macro frames at `handle_a_macro' so
+ that we can identify these in a backtrace. (This change doesn't
+ introduce any significant speed penalty.)
+
+ * eval.c: Added note about `serial-map' using scm_map.
+
+ * read.c, read.h (scm_read_options, scm_read_opts): Removed
+ readline options. They should reside in their own options array.

+
+ * ports.h (SCM_CUC): #define as ~SCM_CRDY instead of 0x001fffffL.
+ This is quite important since the latter clears the

+ every single character read...
+
+1998-11-03 Mikael Djurfeldt <mdj@barbara.nada.kth.se>

+
+ * list.c (scm_sloppy_memq): Removed sloppy_mem_check.
+ (scm_memq, scm_memv, scm_member): Do argument checking *before*
+ starting to search the list. Removed call to sloppy_mem_check.
+
+ * list.c, list.h (scm_delq1_x, scm_delv1_x, scm_delete1_x): New
+ procedures: Same as scm_delq_x et al, but delete maximally one
+ element.
+
+ * options.c (scm_options, scm_init_options): GC-protect option

+
+1998-11-01 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
+

+1998-11-01 Mikael Djurfeldt <mdj@barbara.nada.kth.se>
+
+ * read.c, read.h (scm_read_opts): New read options

+
+ * eval.c (scm_s_expression, scm_s_test, scm_s_body,
+ scm_s_bindings, scm_s_variable, scm_s_clauses, scm_s_formals):
+ Renamed and made global.
+
+ * eval.c, eval.h (SCM_EVALIM): Renamed from EVALIM.
+ (SCM_XEVAL, SCM_XEVALCAR): Renamed from XEVAL, XEVALCAR.
+
+ * evalext.c, evalext.h: New files. Contain non-R5RS things
+ having to do with evaluation.
+
+ * evalext.c (scm_serial_map): New procedure: Version of `map'
+ which guarantees that the procedure is applied to the lists in
+ serial order.
+ (scm_m_sequence_to_list): New syntax: Version of `begin' which
+ returns a list of the results of the body forms instead of the
+ result of the last body form.
+ (scm_definedp, scm_m_undefine): Moved from eval.c
+
+ * evalext.h (scm_m_sequence_to_list): Added declaration.
+
+ * macros.c, macros.h: New files.
+ (scm_procedure_to_syntax, scm_procedure_to_macro,
+ scm_procedure_to_memoizing_macro, scm_macro_p, scm_macro_type,
+ scm_macro_name, scm_macro_transformer): Moved from eval.c
+ (scm_make_synt): Moved from eval.c
+
+ * procs.c, procs.h (scm_procedure_documentation): Moved from eval.c.
+
+ * init.c (scm_boot_guile_1): Added calls to scm_init_macros and
+ scm_init_evalext.
+
+ * Makefile.am: Added evalext.c, evalext.h, macros.c, macros.h.
+
+ * debug.c, print.c: Added #include "macros.h".

+
+ This change adds the ability to use `unread-char' multiple times
+ without interspersed reads and adds the new procedure
+ `unread-string'. The change is optimized for the common case of
+ unreading a single character. This is also the reason behind the
+ choice to store characters in the port itself: in most cases no
+ extra malloc is required.
+
+ The amount of code in some macros in ports.h has been increased to
+ the extent that they would fit better as C functions, but, since
+ this code belongs to the port representation, such functions
+ should be placed in ports.c which would cause calls back and forth
+ between ports.c and genio.c. That is not good for performance.
+ Also, keeping them as macros allows the compiler to do some
+ optimizations which are needed to make the current interface
+ (SCM_CRDYP, SCM_CGETUN, SCM_TRY_CLRDY) efficient.
+
+ One benchmark (Guile startup time) indicates an increase of
+ loading speed of 1%. Another (reading (using `read') boot-9.scm
+ 10 times) shows no change in performance.
+
+ (Caveat: Since Gary is redesigning I/O anyway, no big efforts were
+ made to find a beautiful solution.)
+
+ * ports.h (SCM_CLRDY, SCM_CUNGET, SCM_CGETUN): Rewritten.
+ (SCM_TRY_CLRDY): New macro: Only clear the first unread
+ character. (SCM_CLRDY clears all.)
+ (SCM_N_READY_CHARS): New macro: Returns number of unread
+ characters in a port. Returns wrong answer if SCM_CRDYP is false.
+ (struct scm_port_table): New fields: `entry' contains port table
+ index, `cp' points to last unread char, `cbuf' is the buffer for
+ unread chars, `cbufend' points after end of the character buffer.
+
+ * ports.h, ports.c (scm_unread_string): New procedure.
+ (scm_grow_port_cbuf): New function.
+
+ * ports.c (scm_add_to_port_table, scm_remove_from_port_table):
+ Handle new fields.
+ (scm_generic_fgets), fports.c (local_fgets): Use a loop
+ to read unread characters. Use SCM_TRY_CLRDY instead of
+ SCM_CLRDY.
+
+ * ioext.c (scm_ftell): Use SCM_N_READY_CHARS to correct position.
+
+ * genio.c (scm_getc): Use SCM_TRY_CLRDY instead of SCM_CLRDY.
+
+ * genio.c, genio.h (scm_ungets): New function.
+
+ * genio.c (scm_puts): Removed mysterious TRANSCRIPT_SUPPORT code
+ sections.
+
+1998-10-28 Mikael Djurfeldt <mdj@mdj.nada.kth.se>
