16 | * filesys.c (scm_directory_p): new procedure "directory?" Returns | |
17 | a boolean indicating whether its argument is a directory | |
18 | port as returned by opendir (thanks to Dirk Herrmann for the | |
19 | suggestion.) | |

31 | lacking a setter. | |
32 | ||
bc848f7f MD |
33 | * feature.c, feature.h: (scm_hook_p, scm_hook_empty_p): New |
34 | primitives. (Thanks to Greg Badros); | |

39 | * stime.c (bdtime2c): rewrite the ASSERTs. Accept a value | |
40 | of #f for the 10th vector element to avoid an exception | |
41 | seen by Bernard Urban. | |
42 | (scm_mktime): unneeded ASSERT removed. | |

60 | * guile-snarf.c: Deleted. Snarfing should respect CPP | |
61 | conditionals, so it needs to actually run CPP. Bleah. | |

65 | Handle errors properly in guile-snarf. (Thanks to Han-Wen Nienhuys.) |
66 | * guile-snarf.in: Be sure to exit with an error if CPP does. | |
67 | * Makefile.am (.c.x): Delete the .x file and exit with an error | |
68 | status if guile-snarf exits with an error status. | |
69 | * Makefile.in: Regenerated. | |
70 | ||
9d743bfb JB |
71 | * snarf.h (SCM_GLOBAL_KEYWORD): Call scm_c_make_keyword, not |
72 | scm_makekey, which doesn't exist any more. Guess nobody's using | |
73 | this. | |
74 | ||
2a94fc36 JB |
75 | * guile-snarf.c: New implementation of guile-snarf, meant to be |
76 | more robust than the shell script. I think it's complete, but I | |
77 | haven't tested it at all, and I haven't changed the build process | |
78 | to actually use it. We should compare its output against that of | |
79 | the existing shell script, for all source files. | |
80 | ||
9918cf63 JB |
81 | * guile-snarf.c (parse_args): Abort if we haven't handled some |
82 | character type. | |

84 | 1999-09-03 James Blandy <jimb@mule.m17n.org> |
85 | ||
86 | * load.c (scm_search_path): If the filename has any extension at | |
87 | all, ignore the entire list of extensions. Also, don't check whether | |
88 | the file is accessible. If the file exists, accessible or not, we | |
89 | should return it. Inaccessible files should cause an error later. | |
90 | (Thanks to Keisuke Nishida for the suggestions.) | |

92 | 1999-09-02 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se> |
93 | ||
94 | * gc.c (cleanup, scm_init_storage): Use on_exit if present and | |
95 | atexit not available. (sunos4.1.4 needs it.) | |

99 | I take it all back --- bcopy does handle overlapping source and |
100 | destination areas correctly. At least on every system I could | |
101 | find. But it is better to use AC_REPLACE_FUNCS than to introduce | |
102 | new CPP conditionals. | |
103 | * memmove.c: New file, implementing memmove in terms of bcopy. | |
104 | * scmconfig.h.in: Regenerated. | |
a4ea22c3 JB |
105 | |
106 | Allocators should use the `void *' type for generic pointers. | |
107 | * gc.c (scm_must_malloc, scm_must_realloc, scm_must_free): Change | |
108 | argument and return types. | |
109 | * gc.h: Corresponding changes to prototypes. | |
110 | (Thanks to Forcer.) | |

112 | 1999-08-31 James Blandy <jimb@mule.m17n.org> |
113 | ||
114 | * numbers.c (scm_init_numbers): Claim to support the `complex' | |
115 | feature, as expected by (ice-9 format). (Thanks to Ceri Storey.) | |
116 | ||
dd67f90b JB |
117 | * Makefile.am (check-local): Set GUILE_LOAD_PATH so the tests can |
118 | find (ice-9 boot-9) when Guile was compiled in a separate | |
119 | directory from the source. (Thanks to Rodney Brown.) | |
120 | * Makefile.in: Regenerated. | |
121 | ||
94b4c096 JB |
122 | * procs.c (scm_make_subr_opt): Fix typo. Remember to multiply |
123 | table lengths by the size of a single element when growing the | |
dd67f90b | 124 | table. (Thanks to Bill Schottstaedt.) |

126 | 1999-08-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
127 | ||
128 | * eval.c (SCM_CEVAL): Duplicated the method dispatch code at the | |
129 | SCM_IM_DISPATCH form instead of calling scm_mcache_lookup_cmethod | |
130 | since that cuts down the time for type dispatch by 50%. | |
131 | ||

132 | 1999-08-30 James Blandy <jimb@mule.m17n.org> |
133 | ||
134 | * gh_data.c (gh_set_substr): Revert change of 1999-08-29; bcopy is | |
135 | not a correct substitute for memmove, because it doesn't handle | |
136 | overlapping source and destination areas on many platforms. | |
137 | Overlaps are the primary reason to use memmove in the first place. | |
138 | * ports.c (scm_ungetc): Same. | |
139 | * strop.c (scm_substring_move_x): Same. | |
140 | ||

141 | 1999-08-30 Mikael Djurfeldt <mdj@mdj-pc.nada.kth.se> |
142 | ||
143 | * gc.c (scm_init_storage): Skip registration of cleanup on systems | |
144 | which lack atexit. (Is it important that cleanup is made | |
145 | properly? Maybe we should replace all `exit' with `scm_exit' and | |
146 | call cleanup there?) | |
147 | ||
148 | * struct.c, struct.h (scm_struct_free_0, scm_struct_free_light, | |
149 | scm_struct_free_standard, scm_struct_free_entity): Declared to | |
150 | return scm_sizet instead of size_t. | |
151 | ||
152 | * gdbint.c, strports.c: #include <unistd.h>. (SEEK_SET is defined | |
153 | there on sunos4.1.4.) | |
154 | ||
9a26d6f9 MD |
155 | 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
156 | ||
157 | * numbers.c (scm_lcm): Bugfix: BIGDIG --> SCM_BIGDIG; | |
158 | Account for the case when second argument is unbound. | |
159 | ||
160 | * strorder.c (scm_string_less_p, scm_string_ci_less_p): Bugfix. | |
161 | (Thanks to Karoly Lorentey.) | |
162 | ||
163 | * gh_data.c, ports.c, strop.c: Alternatively use bcopy if memmove | |
b074884f | 164 | isn't present. (Thanks to Suzuki Toshiya.) |
9a26d6f9 MD |
165 | |
166 | * ports.c: Use ANSI C prototypes in definitions. (Thanks to | |
167 | Bernard Urban.) | |
168 | ||
747117b0 MD |
169 | * filesys.c (scm_stat2scm): Conditionally use S_ISLNK. (Thanks to |
170 | Bernard Urban.) | |
9a26d6f9 MD |
171 | |
172 | * dynl-dl.c (RTLD_GLOBAL): Define if non-existent. (Thanks to | |
173 | Bernard Urban and Ian Grant.) | |
174 | ||
175 | * Makefile.am (libguile_la_LDFLAGS): Bumped libguile version | |
176 | again. (1.3.4 will be binary incompatible with 1.3.2 because of a | |
177 | change in the representation of entities and operators.) | |
178 | ||

179 | 1999-08-29 Gary Houston <ghouston@easynet.co.uk> |
180 | ||
181 | * ports.c (scm_ungetc): bugfix: if putback_buf is NULL | |
5c4fe34f | 182 | don't allocate zero bytes (thanks to Bill Schottstaedt). |
6e2e75db | 183 | |

a48a7629 MD |
186 | * procs.c (scm_setter): Converted to use generic dispatch. |
187 | ||
188 | * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized | |
189 | correctly. | |
190 | ||
191 | * load.c (scm_search_path): Don't try extensions which already are | |
192 | present at the end of the filename. | |
193 | (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.) | |
194 | ||
195 | * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.) | |
196 | ||
c5b738b5 MD |
197 | Cleanup and simplification of generic method dispatch. |
198 | Also, the quadruple representation of entity and operator | |
199 | procedures has been replaced with single. | |
200 | ||
201 | * tags.h (SCM_IM_HASH_DISPATCH): Removed. | |
202 | ||
203 | * print.c (scm_isymnames): Removed #@hash-dispatch. | |
204 | ||
205 | * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here | |
206 | from eval.c; Support 0 arity methods. | |
207 | (scm_set_object_procedure_x): Removed scm_sym_atdispatch; | |
208 | (scm_apply_generic_env): Removed. | |
209 | Replaced slots proc0-3 with procedure. | |
210 | ||
211 | * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1, | |
212 | SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by | |
213 | SCM_OPERATOR_PROCEDURE. | |
214 | (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2, | |
215 | SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE. | |
216 | ||
217 | * struct.c, struct.h: Replace 4 procedure slots with one. | |
218 | (scm_struct_i_procedure): Replaces scm_struct_i_procedure. | |
219 | ||
220 | * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of | |
221 | 4. | |
222 | ||
223 | * eval.c (scm_sym_args): Removed. | |
224 | (SCM_CEVAL): Simplified entity application. | |
225 | Moved dispatch code to objects.c. | |
226 | ||
227 | * procprop.c (scm_i_procedure_arity): Bugfix: Handle generics. | |
228 | ||
375c11a3 MD |
229 | 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
230 | ||
231 | * sort.c (closureless): Use scm_eval_body. | |
232 | ||
233 | * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure | |
234 | with a symbol as last form was first called normally and then via | |
235 | `map' or some other mechanism using primitive apply, an ILOC was | |
236 | returned. | |
237 | ||
9de33deb MD |
238 | 1999-08-26 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
239 | ||
240 | This change extends the representation of primitive procedures | |
241 | with more data fields, e.g. a place for documentation and true | |
242 | procedure properties. | |
243 | ||
244 | * procs.c, procs.h (scm_subr_entry): New type: Stores data | |
245 | associated with subrs. | |
246 | (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS, | |
247 | SCM_SUBR_DOC): New macros. | |
248 | (scm_subr_table): New variable. | |
249 | (scm_mark_subr_table): New function. | |
250 | ||
251 | * init.c (scm_boot_guile_1): Call scm_init_subr_table. | |
252 | ||
253 | * gc.c (scm_gc_mark): Don't mark subr names here. | |
254 | (scm_igc): Call scm_mark_subr_table. | |
255 | ||
256 | ||
257 | This change implements a scheme for letting a generic work as a | |
258 | shadow for a primitive procedure. If the primitive procedure | |
259 | can't dispatch on its arguments, control is left over to the | |
260 | generic. Normal wrong type arg errors will be generated until the | |
261 | user has hung the first method on the primitive. | |
262 | ||
263 | * snarf.h (SCM_GPROC, SCM_GPROC1): New macros. | |
264 | ||
265 | * procs.c, procs.h (scm_subr_p): New function (used internally). | |
266 | ||
267 | * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function. | |
268 | ||
269 | * objects.c, objects.h (scm_primitive_generic): New class. | |
270 | ||
271 | * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros. | |
272 | ||
273 | * print.c (scm_iprin1): Print primitive-generics. | |
274 | ||
275 | * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1, | |
276 | SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros. | |
277 | ||
278 | * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta --> | |
279 | SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point | |
280 | primitives). NOTE: This means that it is now *required* to use | |
281 | SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an | |
282 | obscured representation that will be removed in the future anyway, | |
283 | so backward compatibility is no problem here). | |
284 | ||
285 | * numbers.c: Converted most numeric primitives (all but bit | |
286 | comparison operations and bit operations) to dispatch on generic | |
287 | if args don't match. | |
288 | ||
289 | ||
290 | Better support for applying generic functions. | |
291 | ||
292 | * eval.c, eval.h (scm_eval_body): New function. | |
293 | ||
294 | * objects.c (scm_call_generic_0, scm_call_generic_1, | |
295 | scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New | |
296 | functions. | |
297 | ||
298 | ||
299 | Optimization of the generic function dispatch mechanism. | |
300 | ||
301 | * eval.c (SCM_CEVAL): Apply the cmethod directly after having | |
302 | called scm_memoize_method instead of doing a second lookup. | |
303 | ||
304 | * objects.h (scm_memoize_method): Now returns the memoized cmethod. | |
305 | ||
306 | ||
307 | Bugfix | |
308 | ||
309 | * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of | |
310 | scm_sysintern so that the binding connected with the subr name | |
311 | isn't cleared when we give set = 0. | |
312 | ||

314 | 1999-08-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |

9de33deb MD |
316 | More transparent handling of ports with print states. |
317 | ||
07910014 MD |
318 | * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT, |
319 | SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob | |
320 | instead of a pair of a port and a print state. We'll need to cons | |
321 | once extra in scm_printer_apply but the type system will be | |
322 | cleaner, it will mix better with GOOPS, and, it will be even more | |
323 | transparent to the user. | |
324 | ||
325 | * print.c (scm_get_print_state): New procedure: Given an output | |
326 | port, return the print state associated to it in the current print | |
327 | chain, if one exists; | |
328 | (scm_port_with_print_state): New procedure: Associate a | |
329 | print-state with a port. | |
330 | (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P; | |
331 | (scm_printer_apply): Wrap port and pstate as a smob; | |
332 | (print_state_printer): Removed. | |
333 | ||
334 | * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports. | |
335 | ||
336 | * eval.c (scm_init_eval): Use scm_make_smob_type instead of | |
337 | scm_newsmob. | |
338 | ||
339 | * ports.c (scm_output_port_p): Bugfix: Coerce output port before | |
340 | testing (otherwise the port-print-state trick won't be transparent | |
341 | to the user; one example where this caused problems was in the | |
342 | (ice-9 format) module). | |

344 | 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
345 | ||
346 | * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return | |
347 | SCM_UNSPECIFIED instead of the set value. | |

351 | * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH. |
352 | ||
a343458d JB |
353 | * ports.h (enum scm_port_rw_active): New enum, containing |
354 | SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of | |
355 | zero). The debugger knows about enums, but doesn't know about | |
356 | #defines. | |
357 | (typedef scm_port): Declare rw_active member to be an enum | |
358 | scm_port_rw_active. | |
359 | * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER | |
360 | instead of zero. | |
361 | * ports.c (scm_add_to_port_table): Same. | |
362 | * strports.c (st_flush, st_end_input): Same. | |
363 | ||
364 | * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc, | |
365 | scm_must_realloc, and scm_done_malloc as appropriate. | |

367 | 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |

370 | from crashing the interpreter if the less predicate is buggy. | |

375 | (scm_open_file): recognise 'l' for line-buffering. | |
376 | (scm_setvbuf): recognise _IOLBF for line-buffering. | |

381 | of libguile to 5.0. | |
382 | ||
3817c7ce MD |
383 | * eval.c (SCM_APPLY), sort.c (closureless): Expand body when |

387 | ||
388 | * fports.c (fport_write): use memcpy instead of strncpy, in case | |
389 | the data contains NUL. | |

393 | * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.) |
394 | ||
cce0d8d0 MD |
395 | * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h, |
396 | read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line, | |

403 | scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply, | |
404 | scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use | |
405 | scm_sym_ as prefix for symbols. | |
406 | ||
407 | * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed. | |
408 | ||
409 | * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and, | |
410 | scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do, | |

415 | ||
416 | * eval.c (scm_sym_args): Made global. | |
417 | ||
418 | * objects.c (scm_set_object_procedure_x): Disallow setting of | |
419 | procedures for pure generic functions. | |

421 | 1999-08-12 Gary Houston <ghouston@easynet.co.uk> |
422 | ||
423 | * ports.c (scm_seek): one more: was scm_lseek. Also changed the | |
424 | Scheme name from lseek to seek, but lseek was added recently so | |
425 | it shouldn't be a big problem. | |
426 | * ports.c, gdbint.c, ioext.c: changed callers. | |
427 | ||
affc96b5 GH |
428 | 1999-08-11 Gary Houston <ghouston@easynet.co.uk> |
429 | ||
430 | * fports.c (fport_input_waiting): if select is used, return 1 | |
431 | instead of whatever FD_ISSET expands to. maybe it will be useful | |
432 | to interpret the value from the input_waiting ptob procedure as a | |
433 | lower bound on the number of bytes available. | |
434 | ||
435 | * Mikael asked for a few names to be changed... | |
436 | ||
437 | * ports.c (scm_make_port_type): take the write procedure as the | |
438 | second argument instead of the flush procedure. | |
439 | * ports.h (scm_ptob_descriptor): rename the ptob procedures: | |
440 | fflush -> flush, read_flush -> end_input, fclose -> close, | |
441 | fill_buffer -> fill_input, ftruncate -> truncate, | |
442 | input_waiting_p -> input_waiting. | |
443 | ||
444 | * ports.c (end_input_void_port): was read_flush_void_port. | |
445 | (scm_set_port_end_input): was scm_set_port_flush_input. | |
446 | (scm_set_port_flush): was scm_set_port_write. | |
447 | (scm_set_port_input_waiting): was scm_set_port_input_waiting_p | |
448 | (scm_end_input): was scm_read_flush. | |
449 | (scm_fill_input): was scm_fill_buffer. | |
450 | (scm_flush): was scm_fflush. | |
451 | * fports.c (fport_input_waiting): renamed from fport_input_waiting_p. | |
452 | (fport_end_input): was local_read_flush. | |
453 | (fport_flush): was local_fflush. | |
454 | (fport_close): was local_fclose. | |
455 | (fport_truncate): was local_ftruncate. | |
456 | (fport_seek): was local_seek. | |

464 | ||
465 | * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c: | |
466 | change callers. | |

468 | 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
469 | ||
470 | * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch | |
471 | forms now contain the expressions to be dispatched upon instead of | |
472 | depending on a surrounding lambda or let; Generic function | |
473 | dispatch has been optimized; `apply' on a generic function now | |
474 | works a little bit strangely. It uses a trick so that the type | |
475 | dispatch code in SCM_CEVAL can be reused. | |
476 | ||
477 | * objects.h, objects.c (scm_apply_generic_env): Added (used by | |
478 | apply). | |
479 | (scm_operator_p): Added. | |
480 | (scm_sym_atdispatch): Added. | |
481 | (scm_set_object_procedure_x): Modified to handle the new style | |
482 | generic functions. | |
483 | (scm_object_procedures): New debugging procedure. | |

492 | ||
524da6b9 MD |
493 | * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to |

496 | 1999-08-04 Gary Houston <ghouston@easynet.co.uk> |
497 | ||
498 | * ports.c (scm_putc, scm_puts), | |
499 | * unif.c (scm_uniform_array_write): use scm_lfwrite. | |
500 | * ports.c (scm_putc): change type of first argument from int to char. | |

82cc1b11 MD |
502 | 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
503 | ||
504 | * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and | |
505 | SCM_IM_HASH_DISPATCH. | |
506 | ||
507 | * objects.h (SCM_CLASSF_GOOPS_VALID): Added. | |
508 | (scm_si_redfined, scm_si_hashsets): Moved. | |
509 | ||
510 | * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID | |
511 | flag which combines type and status info so that the class | |
512 | redefinition protocol has zero cost during normal execution. | |
513 | ||
31703ab8 GH |
514 | 1999-08-03 Gary Houston <ghouston@easynet.co.uk> |
515 | ||
516 | * ports.h (scm_ptob_descriptor): include a write procedure again. | |
517 | it's more efficient for unbuffered fports (e.g., sockets.) | |
518 | ||
519 | * ports.c (scm_puts): use ptob->write. | |
520 | * vports.c (scm_make_sfptob): set write proc in ptob. | |
521 | * strports.c (scm_make_stptob): set write proc in ptob. | |
522 | * ports.c (write_void_port): new procedure. | |
523 | * vports.c (sf_write): new procedure. | |
524 | * ports.c (scm_lfwrite): use ptob->write. | |
525 | * strports.c (st_write): new procedure. | |
526 | * fports.c (fport_write): new procedure. | |
527 | (scm_make_fptob): set write in ptob to fport_write. | |
528 | * ports.h: prototype for scm_set_port_write. | |
529 | * ports.c (scm_make_port_type): initialise ptob write procedure. | |
530 | (scm_set_port_write): new proc. | |

769f054d JB |
532 | 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com> |
533 | ||
534 | * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry | |
535 | until we've verified that it is actually a port. (Thanks to | |
536 | Lorentey Karoly.) | |

538 | 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
539 | ||
9ffdde1c MD |
540 | * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary |
541 | code, particularly an unnecessary test (len != size, where len == | |
542 | size). (Was this leftovers from debugging code, or have I missed | |
543 | something profound?) | |
544 | ||
5678aae0 MD |
545 | * hashtab.c: Bugfix: Don't declare s_hash_fold without storage |
546 | size. (Thanks to James Dean Palmer.) | |
547 | ||
548 | * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part. | |

551 | 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
552 | ||
553 | * eval.c (scm_m_expand_body): Use scm_cons_source. | |
554 | ||
555 | * struct.c (scm_print_struct): Use vtable name. | |
556 | ||
557 | * print.c (scm_init_print): Set name of print state type. | |
558 | ||
559 | * stacks.c (scm_init_stacks): Set name of stack type. | |

562 | ||
cb4832ae MD |
563 | * eval.c (SCM_CEVAL): Removed old implementation of internal |
564 | define. | |
565 | ||
566 | * gsubr.c, procprop.h (scm_i_inner_name): Removed. | |
567 | ||
568 | * debug.c, debug.h (scm_reverse_lookup): Added. | |
569 | (scm_procedure_name): Use scm_reverse_lookup to lookup the name of | |
570 | internal procedure definitions; Don't use scm_i_inner_name. | |
571 | ||
2a52b429 MD |
572 | * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X): |
573 | New isym operations. | |
574 | ||
b09ef679 MD |
575 | * eval.h: Added prototypes for multi language support functions. |
576 | ||
577 | * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use | |
578 | improper lists in the low-level representation, since that will | |
579 | cause a begin to be prepended at macro expansion. | |
580 | ||
2a52b429 MD |
581 | * eval.c (scm_cons_source): Version of cons which copies source |
582 | properties from an existing cell. | |
6e1fd264 | 583 | (scm_copy_tree, SCM_CEVAL): Use scm_cons_source. |
2a52b429 MD |
584 | |
585 | * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto | |
586 | procedure source before calling scm_unmemocopy instead of faking | |
587 | an environment. | |
588 | ||
589 | 1998-10-25 Marius Vollmer <mvo@zagadka.ping.de> | |
590 | ||
591 | Ported `internal defines' fix from SCM. Original ChangeLog entry: | |
592 | ||
593 | 1998-07-09 Radey Shouman <radey@colorage.com> | |
594 | ||
595 | * eval.c (ceval_1): Modifications to allow rewriting of interal | |
596 | DEFINE to LETREC: If an ISYM is evaluated in non-tail position the | |
597 | body of which it is the CAR is macro expanded by m_expand_body, | |
598 | which rewrites internal DEFINE. | |
599 | ||
600 | (m_expand_body): Added. | |
601 | ||
602 | (m_macroexp1): Added argument to control error checking: | |
603 | m_expand_body may speculatively expand forms in the wrong | |
604 | environments. Made argument number checks conditional on | |
605 | RECKLESS. | |
606 | ||
607 | (m_body): Added, error checks bodies and inserts the ISYM tokens. | |
608 | ||
609 | (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now | |
610 | call m_body. | |
611 | ||
612 | (m_cond): (m_case): (m_quote): Modified to avoid destructively | |
613 | changing their argument forms. Since m_expand_body | |
614 | speculatively macro expands forms the process must be | |
615 | reversible. | |
616 | ||
617 | (m_ident_eqp): Fixed to use proper environment. | |
618 | ||
619 | (renamed_ident): Added DEFER_INTS_EGC. | |
620 | ||
621 | Added prototypes for static functions. | |
622 | ||
623 | * eval.c | |
624 | ||
625 | (undef_cell): New. | |
626 | ||
627 | (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK | |
628 | is false, do not produce an error for unbound variables, return a | |
629 | pointer to cell_undef instead. | |
630 | ||
631 | (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1. | |
632 | ||
633 | (scm_m_body): New. | |
634 | ||
635 | (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid | |
636 | destructively changing their argument forms. Since m_expand_body | |
637 | speculatively macro expands forms the process must be reversible. | |
638 | ||
639 | (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for | |
640 | SCM_IM_LET introduced by named lets. | |
641 | ||
642 | (scm_m_letstar): Use scm_m_body instead of bodycheck. | |
643 | ||
644 | (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and | |
645 | scm_letrec. scm_letrec1 does not check for a null binding and | |
646 | takes an additional argument to specify the ISYM of the body. Use | |
647 | scm_m_body instead of bodycheck. | |
648 | ||
649 | (scm_m_let): Use scm_m_body instead of bodycheck. | |
650 | ||
651 | (scm_m_expand_body, scm_macroexp): New. | |
652 | ||
653 | (unmemocopy): Account for ISYMs introduced by scm_m_body. | |
654 | ||
655 | (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with | |
656 | check=1. Throw error for internal defined that have not been | |
657 | rewritten by scm_m_expand_body. | |
658 | ||
659 | * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp. | |
660 | Removed prototype for SCM_APPLY. | |
661 | ||
662 | * tags.h: Added extern declaration of scm_isymnames. | |

664 | 1999-07-27 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
665 | ||
666 | * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c. | |
667 | ||
668 | * lang.c: New file: Beginning of multi-language support. | |
669 | ||
670 | * init.c (scm_boot_guile_1): Added call to scm_init_lang (). | |
671 | ||
672 | * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case. | |
673 | (scm_dynamic_wind): Added argument checking for the after guard so | |
674 | that we don't add garbage on the dynwind chain. | |
675 | (scm_swap_bindings): Added. | |
676 | ||
677 | * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY, | |
678 | SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c | |
679 | (scm_isymnames): New isyms for multi-language support. | |
680 | ||
681 | * eval.c (scm_nil, scm_t): New symbols. | |
682 | (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special | |
683 | forms for multi-language support. | |

259529f2 MD |
685 | 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
686 | ||
687 | * random.c, random.h (scm_c_default_rstate, scm_c_uniform32): | |
688 | Added. | |
689 | Renamed functions in the random function library interface | |
690 | from scm_i_XXX --> scm_c_XXX. | |
691 | ||
1b9c3dae GH |
692 | 1999-07-25 Gary Houston <ghouston@easynet.co.uk> |
693 | ||

544e9093 MD |
696 | 1999-07-25 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
697 | ||

699 | scm_set_ptob_XXX --> scm_set_port_XXX. | |
700 | ||
f15913d0 MD |
701 | 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
702 | ||
703 | * ports.c, ports.h (scm_make_port_type): New interface for | |
704 | creation of port types (replaces scm_newptob). Just as for the | |
705 | smobs, we need to separate the internal representation of smob | |
706 | types from the interface, so that we easily can add new fields and | |
707 | rearrange things without caring about backward compatibility. | |
708 | This change was forced by the need in GOOPS to create classes | |
709 | representing port types. | |
710 | (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print, | |
711 | scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close, | |
712 | scm_set_ptob_seek, scm_set_ptob_truncate, | |
713 | scm_set_ptob_input_waiting_p): New setters. | |
714 | (scm_newptob): Rewritten to use scm_make_port_type. For backward | |
715 | compatibility. | |
716 | (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor. | |
717 | (scm_prinport): Removed. | |
718 | (scm_port_print): Added. | |
719 | (scm_print_port_mode): Added. | |
720 | (void_port_ptob, print_void_port, close_void_port, noop0): | |
721 | Removed. Removed #include "genio.h" Added #include "objects.h", | |
722 | #include "smobs.h" | |
723 | ||
724 | * fports.c (prinfport): Moved code from ports.c. | |
725 | (local_free): Added. | |
726 | (scm_fptob): Removed. Instead use new interface. | |
727 | (scm_make_fptob): Added. (Need to create basic ports in a | |
728 | specific order in ports.c.) | |
729 | ||
730 | * strports.c (scm_stptob, prinstpt, noop0): Removed | |
731 | (scm_make_stptob): Added. | |
732 | ||
733 | * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed. | |
734 | (scm_make_sfport): Added. | |
735 | ||
736 | * filesys.c (scm_dir_print): Don't use the port printing code. | |
737 | Instead provide specific directory printer. | |
738 | ||
739 | * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free. | |
740 | ||
741 | * ioext.c (scm_redirect_port): Replaced scm_ptobfuns --> | |
742 | scm_ptob_descriptor. | |
743 | ||
744 | * smob.c (scm_smob_print): Handle non-existing type name nicely. | |
745 | Removed #include "genio.h" | |
746 | ||
747 | * objects.c (scm_make_port_classes): New function ptr. | |
748 | ||
69bc9ff3 GH |
749 | 1999-07-24 Gary Houston <ghouston@easynet.co.uk> |
750 | ||
751 | * gdbint.c (gdb_print, gdb_read): call scm_truncate_file. | |
752 | ||
753 | * ports.c (scm_truncate_file): renamed from scm_ftruncate. | |
754 | allow the 1st argument to be a fdes or filename as well as a | |
755 | port (as in the filesys.c version). | |
756 | ||
757 | * filesys.c (scm_truncate_file): removed. | |
