1 | 1999-08-29 Gary Houston <ghouston@easynet.co.uk> |
2 | ||
3 | * ports.c (scm_ungetc): bugfix: if putback_buf is NULL | |
5c4fe34f | 4 | don't allocate zero bytes (thanks to Bill Schottstaedt). |

8 | * procs.c (scm_setter): Converted to use generic dispatch. |
9 | ||
10 | * eval.c, eval.h: Bugfix: scm_sym_apply was not initialized | |
11 | correctly. | |
12 | ||
13 | * load.c (scm_search_path): Don't try extensions which already are | |
14 | present at the end of the filename. | |
15 | (scm_init_load): Check .scm first. (Thanks to Keisuke Nishida.) | |
16 | ||
17 | * stacks.c (scm_sym_apply): Removed. (Thanks to Ken Raeburn.) | |
18 | ||

19 | Cleanup and simplification of generic method dispatch. |
20 | Also, the quadruple representation of entity and operator | |
21 | procedures has been replaced with single. | |
22 | ||
23 | * tags.h (SCM_IM_HASH_DISPATCH): Removed. | |
24 | ||
25 | * print.c (scm_isymnames): Removed #@hash-dispatch. | |
26 | ||
27 | * objects.c, objects.h (scm_mcache_lookup_cmethod): Moved here | |
28 | from eval.c; Support 0 arity methods. | |
29 | (scm_set_object_procedure_x): Removed scm_sym_atdispatch; | |
30 | (scm_apply_generic_env): Removed. | |
31 | Replaced slots proc0-3 with procedure. | |
32 | ||
33 | * objects.h (SCM_OPERATOR_PROC_0, SCM_OPERATOR_PROC_1, | |
34 | SCM_OPERATOR_PROC_2, SCM_OPERATOR_PROC_3): Replaced by | |
35 | SCM_OPERATOR_PROCEDURE. | |
36 | (SCM_ENTITY_PROC_0, SCM_ENTITY_PROC_1, SCM_ENTITY_PROC_2, | |
37 | SCM_ENTITY_PROC_3): Replaced by SCM_ENTITY_PROCEDURE. | |
38 | ||
39 | * struct.c, struct.h: Replace 4 procedure slots with one. | |
40 | (scm_struct_i_procedure): Replaces scm_struct_i_procedure. | |
41 | ||
42 | * gc.c (scm_gc_mark): Mark 1 procedure slot in entities instead of | |
43 | 4. | |
44 | ||
45 | * eval.c (scm_sym_args): Removed. | |
46 | (SCM_CEVAL): Simplified entity application. | |
47 | Moved dispatch code to objects.c. | |
48 | ||

51 | 1999-08-29 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
52 | ||
53 | * sort.c (closureless): Use scm_eval_body. | |
54 | ||
55 | * eval.c (SCM_APPLY): Fixed serious evaluator bug: If a closure | |
56 | with a symbol as last form was first called normally and then via | |
57 | `map' or some other mechanism using primitive apply, an ILOC was | |
58 | returned. | |

61 | ||
62 | This change extends the representation of primitive procedures | |
63 | with more data fields, e.g. a place for documentation and true | |
64 | procedure properties. | |
65 | ||
66 | * procs.c, procs.h (scm_subr_entry): New type: Stores data | |
67 | associated with subrs. | |
68 | (SCM_SUBRNUM, SCM_SUBR_ENTRY, SCM_SUBR_GENERIC, SCM_SUBR_PROPS, | |
69 | SCM_SUBR_DOC): New macros. | |
70 | (scm_subr_table): New variable. | |
71 | (scm_mark_subr_table): New function. | |
72 | ||
73 | * init.c (scm_boot_guile_1): Call scm_init_subr_table. | |
74 | ||
75 | * gc.c (scm_gc_mark): Don't mark subr names here. | |
76 | (scm_igc): Call scm_mark_subr_table. | |
77 | ||
78 | ||
79 | This change implements a scheme for letting a generic work as a | |
80 | shadow for a primitive procedure. If the primitive procedure | |
81 | can't dispatch on its arguments, control is left over to the | |
82 | generic. Normal wrong type arg errors will be generated until the | |
83 | user has hung the first method on the primitive. | |
84 | ||
85 | * snarf.h (SCM_GPROC, SCM_GPROC1): New macros. | |
86 | ||
87 | * procs.c, procs.h (scm_subr_p): New function (used internally). | |
88 | ||
89 | * gsubr.c, gsubr.h (scm_make_gsubr_with_generic): New function. | |
90 | ||
91 | * objects.c, objects.h (scm_primitive_generic): New class. | |
92 | ||
93 | * objects.h (SCM_CMETHOD_CODE, SCM_CMETHOD_ENV): New macros. | |
94 | ||
95 | * print.c (scm_iprin1): Print primitive-generics. | |
96 | ||
97 | * __scm.h (SCM_WTA_DISPATCH_1, SCM_GASSERT1, | |
98 | SCM_WTA_DISPATCH_2, SCM_GASSERT2): New macros. | |
99 | ||
100 | * eval.c (SCM_CEVAL, SCM_APPLY): Replace scm_wta --> | |
101 | SCM_WTA_DISPATCH_1 for scm_cxr's (unary floating point | |
102 | primitives). NOTE: This means that it is now *required* to use | |
103 | SCM_GPROC1 when creating float scm_cxr's (float scm_cxr's is an | |
104 | obscured representation that will be removed in the future anyway, | |
105 | so backward compatibility is no problem here). | |
106 | ||
107 | * numbers.c: Converted most numeric primitives (all but bit | |
108 | comparison operations and bit operations) to dispatch on generic | |
109 | if args don't match. | |
110 | ||
111 | ||
112 | Better support for applying generic functions. | |
113 | ||
114 | * eval.c, eval.h (scm_eval_body): New function. | |
115 | ||
116 | * objects.c (scm_call_generic_0, scm_call_generic_1, | |
117 | scm_call_generic_2, scm_call_generic_3, scm_apply_generic): New | |
118 | functions. | |
119 | ||
120 | ||
121 | Optimization of the generic function dispatch mechanism. | |
122 | ||
123 | * eval.c (SCM_CEVAL): Apply the cmethod directly after having | |
124 | called scm_memoize_method instead of doing a second lookup. | |
125 | ||
126 | * objects.h (scm_memoize_method): Now returns the memoized cmethod. | |
127 | ||
128 | ||
129 | Bugfix | |
130 | ||
131 | * procs.c (scm_make_subr_opt): Use scm_sysintern0 instead of | |
132 | scm_sysintern so that the binding connected with the subr name | |
133 | isn't cleared when we give set = 0. | |
134 | ||

138 | More transparent handling of ports with print states. |
139 | ||
07910014 MD |
140 | * print.h (SCM_PORT_WITH_PS_P, SCM_PORT_WITH_PS_PORT, |
141 | SCM_PORT_WITH_PS_PS): Represent ports with print states as a smob | |
142 | instead of a pair of a port and a print state. We'll need to cons | |
143 | once extra in scm_printer_apply but the type system will be | |
144 | cleaner, it will mix better with GOOPS, and, it will be even more | |
145 | transparent to the user. | |
146 | ||
147 | * print.c (scm_get_print_state): New procedure: Given an output | |
148 | port, return the print state associated to it in the current print | |
149 | chain, if one exists; | |
150 | (scm_port_with_print_state): New procedure: Associate a | |
151 | print-state with a port. | |
152 | (scm_valid_oport_value_p): Use SCM_PORT_WITH_PS_P; | |
153 | (scm_printer_apply): Wrap port and pstate as a smob; | |
154 | (print_state_printer): Removed. | |
155 | ||
156 | * objects.c (scm_class_of): Treat scm_tc16_port_with_ps as ports. | |
157 | ||
158 | * eval.c (scm_init_eval): Use scm_make_smob_type instead of | |
159 | scm_newsmob. | |
160 | ||
161 | * ports.c (scm_output_port_p): Bugfix: Coerce output port before | |
162 | testing (otherwise the port-print-state trick won't be transparent | |
163 | to the user; one example where this caused problems was in the | |
164 | (ice-9 format) module). | |
165 | ||

166 | 1999-08-23 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
167 | ||
168 | * eval.c (SCM_CEVAL): Let the SCM_IM_SLOT_SET_X form return | |
169 | SCM_UNSPECIFIED instead of the set value. | |
170 | ||

171 | 1999-08-20 James Blandy <jimb@mule.m17n.org> |
172 | ||
f8c9d497 JB |
173 | * load.c (scm_init_load_path): Remove support for SCHEME_LOAD_PATH. |
174 | ||
a343458d JB |
175 | * ports.h (enum scm_port_rw_active): New enum, containing |
176 | SCM_PORT_READ, SCM_PORT_WRITE, and SCM_PORT_NEITHER (instead of | |
177 | zero). The debugger knows about enums, but doesn't know about | |
178 | #defines. | |
179 | (typedef scm_port): Declare rw_active member to be an enum | |
180 | scm_port_rw_active. | |
181 | * fports.c (fport_flush, fport_end_input): Use SCM_PORT_NEITHER | |
182 | instead of zero. | |
183 | * ports.c (scm_add_to_port_table): Same. | |
184 | * strports.c (st_flush, st_end_input): Same. | |
185 | ||
186 | * ioext.c (scm_do_read_line, scm_read_line): Use scm_must_malloc, | |
187 | scm_must_realloc, and scm_done_malloc as appropriate. | |
188 | ||

189 | 1999-08-20 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
190 | ||
191 | * sort.c (quicksort): Added condition to protect the algorithm | |
192 | from crashing the interpreter if the less predicate is buggy. | |
193 | ||

194 | 1999-08-19 Gary Houston <ghouston@easynet.co.uk> |
195 | ||
196 | * fports.c (fport_write): fix line-buffering mode again. | |
197 | (scm_open_file): recognise 'l' for line-buffering. | |
198 | (scm_setvbuf): recognise _IOLBF for line-buffering. | |

201 | ||
266bf340 MD |
202 | * Makefile.am (libguile_la_LDFLAGS): Increased the version number |
203 | of libguile to 5.0. | |
204 | ||
3817c7ce MD |
205 | * eval.c (SCM_APPLY), sort.c (closureless): Expand body when |
206 | evaluating closures. | |
207 | ||

208 | 1999-08-18 Gary Houston <ghouston@easynet.co.uk> |
209 | ||
210 | * fports.c (fport_write): use memcpy instead of strncpy, in case | |
211 | the data contains NUL. | |

215 | * gh.h (gh_vector_to_list): Bugfix. (Thanks to Frank Cieslok.) |
216 | ||
cce0d8d0 MD |
217 | * backtrace.c, debug.c, eval.c, eval.h, gsubr.c, procprop.h, |
218 | read.c, srcprop.c, srcprop.h (scm_i_filename, scm_i_line, | |
219 | scm_i_column, scm_i_copy, scm_i_name, scm_i_lambda, scm_i_source, | |
220 | scm_i_more, scm_i_procname, scm_i_dot, scm_i_arrow, scm_i_else, | |

225 | scm_i_define, scm_i_letrec, scm_i_let, scm_i_atapply, | |
226 | scm_i_atcall_cc, scm_i_breakpoint): Renamed: Consequently use | |
227 | scm_sym_ as prefix for symbols. | |
228 | ||
229 | * debug.c (scm_i_proc, scm_i_args, scm_i_eval_args): Removed. | |
230 | ||
231 | * eval.c, eval.h (scm_sym_begin, scm_sym_if, scm_sym_and, | |
232 | scm_sym_case, scm_sym_cond, scm_sym_letstar, scm_sym_do, | |
233 | scm_sym_define, scm_sym_letrec, scm_sym_atapply, | |
234 | scm_sym_atcall_cc): Made global. | |

236 | 1999-08-16 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
237 | ||
238 | * eval.c (scm_sym_args): Made global. | |
239 | ||
240 | * objects.c (scm_set_object_procedure_x): Disallow setting of | |
241 | procedures for pure generic functions. | |

c94577b4 GH |
243 | 1999-08-12 Gary Houston <ghouston@easynet.co.uk> |
244 | ||
245 | * ports.c (scm_seek): one more: was scm_lseek. Also changed the | |
246 | Scheme name from lseek to seek, but lseek was added recently so | |
247 | it shouldn't be a big problem. | |
248 | * ports.c, gdbint.c, ioext.c: changed callers. | |
249 | ||
affc96b5 GH |
250 | 1999-08-11 Gary Houston <ghouston@easynet.co.uk> |
251 | ||
252 | * fports.c (fport_input_waiting): if select is used, return 1 | |
253 | instead of whatever FD_ISSET expands to. maybe it will be useful | |
254 | to interpret the value from the input_waiting ptob procedure as a | |
255 | lower bound on the number of bytes available. | |
256 | ||
257 | * Mikael asked for a few names to be changed... | |
258 | ||
259 | * ports.c (scm_make_port_type): take the write procedure as the | |
260 | second argument instead of the flush procedure. | |
261 | * ports.h (scm_ptob_descriptor): rename the ptob procedures: | |
262 | fflush -> flush, read_flush -> end_input, fclose -> close, | |
263 | fill_buffer -> fill_input, ftruncate -> truncate, | |
264 | input_waiting_p -> input_waiting. | |
265 | ||
266 | * ports.c (end_input_void_port): was read_flush_void_port. | |
267 | (scm_set_port_end_input): was scm_set_port_flush_input. | |
268 | (scm_set_port_flush): was scm_set_port_write. | |
269 | (scm_set_port_input_waiting): was scm_set_port_input_waiting_p | |
270 | (scm_end_input): was scm_read_flush. | |
271 | (scm_fill_input): was scm_fill_buffer. | |
272 | (scm_flush): was scm_fflush. | |
273 | * fports.c (fport_input_waiting): renamed from fport_input_waiting_p. | |
274 | (fport_end_input): was local_read_flush. | |
275 | (fport_flush): was local_fflush. | |
276 | (fport_close): was local_fclose. | |
277 | (fport_truncate): was local_ftruncate. | |
278 | (fport_seek): was local_seek. | |
279 | (fport_free): was local_free. | |
280 | (fport_fill_input): was fport_fill_buffer. | |
281 | * strports.c (st_end_input): was st_read_flush. | |
282 | (st_truncate): was st_ftruncate. | |
283 | * vports.c: (sf_flush): was sfflush. | |
284 | (sf_close): was sfclose. | |
285 | (sf_fill_input): was sf_fill_buffer. | |
286 | ||
287 | * ports.c, fports.c, strports, vports.c, ioext.c, unif.c, filesys.c: | |
288 | change callers. | |

df061ffc MD |
290 | 1999-08-06 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
291 | ||
292 | * eval.c (SCM_IM_DISPATCH): Rewrote dispatch protocol. Dispatch | |
293 | forms now contain the expressions to be dispatched upon instead of | |
294 | depending on a surrounding lambda or let; Generic function | |
295 | dispatch has been optimized; `apply' on a generic function now | |
296 | works a little bit strangely. It uses a trick so that the type | |
297 | dispatch code in SCM_CEVAL can be reused. | |
298 | ||
299 | * objects.h, objects.c (scm_apply_generic_env): Added (used by | |
300 | apply). | |
301 | (scm_operator_p): Added. | |
302 | (scm_sym_atdispatch): Added. | |
303 | (scm_set_object_procedure_x): Modified to handle the new style | |
304 | generic functions. | |
305 | (scm_object_procedures): New debugging procedure. | |

312 | ||
eba96884 MD |
313 | * feature.c, feature.h (scm_c_run_hook): Added. |
314 | ||
524da6b9 MD |
315 | * eval.c (SCM_CEVAL:SCM_IM_DISPATCH): Bugfix: Jump back to |
316 | cdrxnoap and loopnoap instead of begin and loop. | |

318 | 1999-08-04 Gary Houston <ghouston@easynet.co.uk> |
319 | ||
320 | * ports.c (scm_putc, scm_puts), | |
321 | * unif.c (scm_uniform_array_write): use scm_lfwrite. | |
322 | * ports.c (scm_putc): change type of first argument from int to char. | |
323 | ||
82cc1b11 MD |
324 | 1999-08-04 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
325 | ||
326 | * eval.c (SCM_CEVAL): Improvements to SCM_IM_DISPATCH and | |
327 | SCM_IM_HASH_DISPATCH. | |
328 | ||
329 | * objects.h (SCM_CLASSF_GOOPS_VALID): Added. | |
330 | (scm_si_redfined, scm_si_hashsets): Moved. | |
331 | ||
332 | * objects.c (scm_class_of): Use the new SCM_CLASSF_GOOPS_VALID | |
333 | flag which combines type and status info so that the class | |
334 | redefinition protocol has zero cost during normal execution. | |
335 | ||
31703ab8 GH |
336 | 1999-08-03 Gary Houston <ghouston@easynet.co.uk> |
337 | ||
338 | * ports.h (scm_ptob_descriptor): include a write procedure again. | |
339 | it's more efficient for unbuffered fports (e.g., sockets.) | |
340 | ||
341 | * ports.c (scm_puts): use ptob->write. | |
342 | * vports.c (scm_make_sfptob): set write proc in ptob. | |
343 | * strports.c (scm_make_stptob): set write proc in ptob. | |
344 | * ports.c (write_void_port): new procedure. | |
345 | * vports.c (sf_write): new procedure. | |
346 | * ports.c (scm_lfwrite): use ptob->write. | |
347 | * strports.c (st_write): new procedure. | |
348 | * fports.c (fport_write): new procedure. | |
349 | (scm_make_fptob): set write in ptob to fport_write. | |
350 | * ports.h: prototype for scm_set_port_write. | |
351 | * ports.c (scm_make_port_type): initialise ptob write procedure. | |
352 | (scm_set_port_write): new proc. | |
353 | ||

354 | 1999-08-01 Jim Blandy <jimb@savonarola.red-bean.com> |
355 | ||
356 | * ports.c (scm_char_ready_p): Don't try to find PORT's ptab entry | |
357 | until we've verified that it is actually a port. (Thanks to | |
358 | Lorentey Karoly.) | |
359 | ||

360 | 1999-07-31 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
361 | ||
9ffdde1c MD |
362 | * gc.c (scm_must_malloc, scm_must_realloc): Removed unnecessary |
363 | code, particularly an unnecessary test (len != size, where len == | |
364 | size). (Was this leftovers from debugging code, or have I missed | |
365 | something profound?) | |
366 | ||
5678aae0 MD |
367 | * hashtab.c: Bugfix: Don't declare s_hash_fold without storage |
368 | size. (Thanks to James Dean Palmer.) | |
369 | ||
370 | * numbers.c (scm_makdbl): Bugfix: Initialize imaginary part. | |
371 | (Thanks to Lorentey Karoly.) | |

373 | 1999-07-30 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
374 | ||
375 | * eval.c (scm_m_expand_body): Use scm_cons_source. | |
376 | ||
377 | * struct.c (scm_print_struct): Use vtable name. | |
378 | ||
379 | * print.c (scm_init_print): Set name of print state type. | |

cb4832ae MD |
385 | * eval.c (SCM_CEVAL): Removed old implementation of internal |
386 | define. | |
387 | ||
388 | * gsubr.c, procprop.h (scm_i_inner_name): Removed. | |
389 | ||
390 | * debug.c, debug.h (scm_reverse_lookup): Added. | |
391 | (scm_procedure_name): Use scm_reverse_lookup to lookup the name of | |
392 | internal procedure definitions; Don't use scm_i_inner_name. | |
393 | ||
2a52b429 MD |
394 | * eval.c, tags.h, print.c (SCM_IM_SLOT_REF, SCM_IM_SLOT_SET_X): |
395 | New isym operations. | |
396 | ||
b09ef679 MD |
397 | * eval.h: Added prototypes for multi language support functions. |
398 | ||
399 | * eval.c (SCM_IM_DISPATCH, SCM_IM_HASH_DISPATCH): Don't use | |
400 | improper lists in the low-level representation, since that will | |
401 | cause a begin to be prepended at macro expansion. | |
402 | ||
2a52b429 MD |
403 | * eval.c (scm_cons_source): Version of cons which copies source |
404 | properties from an existing cell. | |
6e1fd264 | 405 | (scm_copy_tree, SCM_CEVAL): Use scm_cons_source. |
2a52b429 MD |
406 | |
407 | * debug.c (scm_procedure_source): Cons SCM_IM_LAMBDA onto | |
408 | procedure source before calling scm_unmemocopy instead of faking | |
409 | an environment. | |

413 | Ported `internal defines' fix from SCM. Original ChangeLog entry: | |
414 | ||
415 | 1998-07-09 Radey Shouman <radey@colorage.com> | |
416 | ||
417 | * eval.c (ceval_1): Modifications to allow rewriting of interal | |
418 | DEFINE to LETREC: If an ISYM is evaluated in non-tail position the | |
419 | body of which it is the CAR is macro expanded by m_expand_body, | |
420 | which rewrites internal DEFINE. | |
421 | ||
422 | (m_expand_body): Added. | |
423 | ||
424 | (m_macroexp1): Added argument to control error checking: | |
425 | m_expand_body may speculatively expand forms in the wrong | |
426 | environments. Made argument number checks conditional on | |
427 | RECKLESS. | |
428 | ||
429 | (m_body): Added, error checks bodies and inserts the ISYM tokens. | |
430 | ||
431 | (m_lambda): (m_letstar): (m_letrec1): (m_letrec): (m_let): Now | |
432 | call m_body. | |
433 | ||
434 | (m_cond): (m_case): (m_quote): Modified to avoid destructively | |
435 | changing their argument forms. Since m_expand_body | |
436 | speculatively macro expands forms the process must be | |
437 | reversible. | |
438 | ||
439 | (m_ident_eqp): Fixed to use proper environment. | |
440 | ||
441 | (renamed_ident): Added DEFER_INTS_EGC. | |
442 | ||
443 | Added prototypes for static functions. | |
444 | ||
445 | * eval.c | |
446 | ||
447 | (undef_cell): New. | |
448 | ||
449 | (scm_lookupcar1, scm_lookupcar): Added CHECK argument. When CHECK | |
450 | is false, do not produce an error for unbound variables, return a | |
451 | pointer to cell_undef instead. | |
452 | ||
453 | (EVALCELLCAR, XEVALCAR): Call scm_lookupcar with check=1. | |
454 | ||
455 | (scm_m_body): New. | |
456 | ||
457 | (scm_m_cond, scm_m_case, scm_m_quote): Modified to avoid | |
458 | destructively changing their argument forms. Since m_expand_body | |
459 | speculatively macro expands forms the process must be reversible. | |
460 | ||
461 | (scm_m_lambda): Use scm_m_body instead of bodycheck. Account for | |
462 | SCM_IM_LET introduced by named lets. | |
463 | ||
464 | (scm_m_letstar): Use scm_m_body instead of bodycheck. | |
465 | ||
466 | (scm_m_letrec1, scm_letrec): Split scm_letrec into scm_letrec1 and | |
467 | scm_letrec. scm_letrec1 does not check for a null binding and | |
468 | takes an additional argument to specify the ISYM of the body. Use | |
469 | scm_m_body instead of bodycheck. | |
470 | ||
471 | (scm_m_let): Use scm_m_body instead of bodycheck. | |
472 | ||
473 | (scm_m_expand_body, scm_macroexp): New. | |
474 | ||
475 | (unmemocopy): Account for ISYMs introduced by scm_m_body. | |
476 | ||
477 | (ceval, deval): Call scm_m_expand_body. Call scm_lookupcar with | |
478 | check=1. Throw error for internal defined that have not been | |
479 | rewritten by scm_m_expand_body. | |
480 | ||
481 | * eval.h: Added prototypes for scm_m_expand_body and scm_macroexp. | |
482 | Removed prototype for SCM_APPLY. | |
483 | ||
484 | * tags.h: Added extern declaration of scm_isymnames. | |

487 | ||
488 | * Makefile.am (EXTRA_libguile_la_SOURCES): Added lang.c. | |
489 | ||
490 | * lang.c: New file: Beginning of multi-language support. | |
491 | ||
492 | * init.c (scm_boot_guile_1): Added call to scm_init_lang (). | |
493 | ||
494 | * dynwind.c (scm_dowinds): Removed obsolete wind_key #f case. | |
495 | (scm_dynamic_wind): Added argument checking for the after guard so | |
496 | that we don't add garbage on the dynwind chain. | |
497 | (scm_swap_bindings): Added. | |
498 | ||
499 | * tags.h, print.c (SCM_IM_NIL_COND, SCM_IM_NIL_IFY, SCM_IM_T_IFY, | |
500 | SCM_IM_0_COND, SCM_IM_0_IFY, SCM_IM_1_IFY), print.c | |
501 | (scm_isymnames): New isyms for multi-language support. | |
502 | ||
503 | * eval.c (scm_nil, scm_t): New symbols. | |
504 | (nil-cond, nil-ify, t-ify, 0-cond, 0-ify, 1-ify): New special | |
505 | forms for multi-language support. | |

508 | ||
509 | * random.c, random.h (scm_c_default_rstate, scm_c_uniform32): | |
510 | Added. | |
511 | Renamed functions in the random function library interface | |
512 | from scm_i_XXX --> scm_c_XXX. | |

f15913d0 MD |
523 | 1999-07-24 Mikael Djurfeldt <mdj@thalamus.nada.kth.se> |
524 | ||
525 | * ports.c, ports.h (scm_make_port_type): New interface for | |
526 | creation of port types (replaces scm_newptob). Just as for the | |
527 | smobs, we need to separate the internal representation of smob | |
528 | types from the interface, so that we easily can add new fields and | |
529 | rearrange things without caring about backward compatibility. | |
530 | This change was forced by the need in GOOPS to create classes | |
531 | representing port types. | |
532 | (scm_set_ptob_mark, scm_set_ptob_free, scm_set_ptob_print, | |
533 | scm_set_ptob_equalp, scm_set_ptob_flush_input, scm_set_ptob_close, | |
534 | scm_set_ptob_seek, scm_set_ptob_truncate, | |
535 | scm_set_ptob_input_waiting_p): New setters. | |
536 | (scm_newptob): Rewritten to use scm_make_port_type. For backward | |
537 | compatibility. | |
538 | (scm_ptobs): Changed type scm_ptobfuns --> scm_ptob_descriptor. | |
539 | (scm_prinport): Removed. | |
540 | (scm_port_print): Added. | |
541 | (scm_print_port_mode): Added. | |
542 | (void_port_ptob, print_void_port, close_void_port, noop0): | |
543 | Removed. Removed #include "genio.h" Added #include "objects.h", | |
544 | #include "smobs.h" | |
545 | ||
546 | * fports.c (prinfport): Moved code from ports.c. | |
547 | (local_free): Added. | |
548 | (scm_fptob): Removed. Instead use new interface. | |
549 | (scm_make_fptob): Added. (Need to create basic ports in a | |
550 | specific order in ports.c.) | |
551 | ||
552 | * strports.c (scm_stptob, prinstpt, noop0): Removed | |
553 | (scm_make_stptob): Added. | |
554 | ||
555 | * vports.c (scm_sfport, prinsfpt, sf_read_flush, noop0): Removed. | |
556 | (scm_make_sfport): Added. | |
557 | ||
558 | * filesys.c (scm_dir_print): Don't use the port printing code. | |
559 | Instead provide specific directory printer. | |
560 | ||
561 | * gc.c (scm_gc_sweep): Use value returned from scm_ptobs[].free. | |
562 | ||
563 | * ioext.c (scm_redirect_port): Replaced scm_ptobfuns --> | |
564 | scm_ptob_descriptor. | |
565 | ||
566 | * smob.c (scm_smob_print): Handle non-existing type name nicely. | |
567 | Removed #include "genio.h" | |
568 | ||
569 | * objects.c (scm_make_port_classes): New function ptr. | |
570 | ||
69bc9ff3 GH |
571 | 1999-07-24 Gary Houston <ghouston@easynet.co.uk> |
572 | ||
573 | * gdbint.c (gdb_print, gdb_read): call scm_truncate_file. | |
574 | ||
575 | * ports.c (scm_truncate_file): renamed from scm_ftruncate. | |
576 | allow the 1st argument to be a fdes or filename as well as a | |
577 | port (as in the filesys.c version). | |
578 | ||
579 | * filesys.c (scm_truncate_file): removed. | |

596 | ||
597 | * init.c: Make sure that scm_post_boot_init_modules is called only | |
598 | once. (Important when using a dumped image.; Thanks to Bernard | |
599 | Urban.) | |
