3 * examine.q factor_stats.[ch] Changed stderr to se_mean to avoid
6 Sun Nov 21 10:32:41 WST 2004 John Darrington <john@darrington.wattle.id.au>
8 * var-labs.c (var_to_string) Now returns null if the variable is null

23 John Darrington <john@darrington.wattle.id.au>
25 * settings.h set.c glob.[ch] frequencies.q q2c.c error.c lexer.[ch]
28 Plugged some memory leaks
30 Mon Nov 15 23:47:40 2004 Ben Pfaff <blp@gnu.org>
32 Adopt GSL random number generators, paving the way for providing
33 the complete suite of random number generators on expressions.
35 * Makefile.am: Remove random.c, random.h.
41 * algorithm.c: (algo_default_random) Use GSL functions.
43 * casefile.c: (test_casefile) Use GSL RNG functions.
45 * expr-evl.c: (expr_evaluate) Use GSL RNG functions for OP_NORMAL,
48 * sample.c: (cmd_sample) Use GSL RNG functions.
49 (sample_trns_proc) Ditto.
51 * set.q: (static var set_seed) Removed.
52 (static var seed_flag) Removed.
53 (static var rng) New variable.
54 (aux_stc_custom_seed) No seed value anymore, don't print anything.
55 (stc_custom_seed) Use new seed functions.
56 (seed_is_set) Removed.
57 (get_rng) New function that composes the entire external
59 (set_rng) New function.
60 (random_seed) New function.
62 Mon Nov 15 22:08:25 2004 Ben Pfaff <blp@gnu.org>
64 * expr-evl.c: (expr_evaluate) Fix XDATE.JDAY formula. Thanks to
65 John Darrington <john@darrington.wattle.id.au> for reporting this
68 Tue Nov 16 13:19:18 WST 2004 John Darrington <john@darrington.wattle.id.au>
70 * permissions.c command.def Added the PERMISSIONS command
73 Mon Nov 15 01:33:32 2004 Ben Pfaff <blp@gnu.org>
75 * q2c.c: (dump_header) Don't try to emit #includes at very top of
76 output file because that will precede #include <config.h>, which
78 (main) Add needed headers to /* (header) */ code.
80 Mon Nov 15 01:21:36 2004 Ben Pfaff <blp@gnu.org>
82 Instead of making system or portable file readers responsible for
83 dropping and reordering variables, make them read full cases and
84 let the caller take care of any changes.
86 * get.c: New "case map" structure to handle this. Use for GET,
87 IMPORT, MATCH FILES. Essentially rewrite the whole file.
89 * pfm-read.c: (pfm_read_case) Read into provided case. Signature
90 changed appropriately.
92 * sfm-read.c: (sfm_read_case) Ditto.
94 Mon Nov 15 00:47:45 2004 Ben Pfaff <blp@gnu.org>
96 Decided that case_serialize() and case_unserialize() were too
97 abstract. Also we need a couple more functions to avoid excessive
98 copying for data in/out fast paths.
100 * case.c: (case_serial_size) Removed.
101 (case_serialize) Rename case_to_values() and make its argument
102 explicitly an array of union values.
103 (case_unserialize) Rename case_from_values() and make its argument
104 explicitly an array of union values.
105 (case_data_all) New function.
106 (case_data_all_rw) New function.
108 * casefile.c: (struct casefile) Change buffer from array of
109 unsigned char to array of union value for better accuracy.
110 Redefine buffer_used and buffer_size in terms of values, not
111 bytes. Remove case_size because it is now redundant with
112 value_cnt. Fix up all references to these members.
114 Mon Nov 15 00:45:46 2004 Ben Pfaff <blp@gnu.org>
116 * barchart.c: (struct subcat) Make `label' member const to silence
117 GCC warning with -Wwrite-strings.
119 * cartesian.c: (struct dataset) Ditto.
121 * case.c: Don't re-define NDEBUG if already defined.
122 Add lots of comments.
124 * str.c: Fix includes.
126 * crosstabs.q: Fix includes.
128 * examine.q: Fix includes. Fix GCC warning about unused
131 * frequencies.q: (stat macro) Removed and replaced where used by
134 * list.q: Fix includes.
136 * oneway.q: Fix includes.
138 * piechart.c: Fix includes. Only define M_PI if not already
141 * sfm-read.c: (bswap) New function.
142 (bswap_int32) Write in terms of bswap.
145 * str.c: (ds_data) Add external definition here, needed because
146 str.h has only an `extern inline' version.
148 * value-labels.c: Fix includes.
150 Mon Nov 15 00:40:55 2004 Ben Pfaff <blp@gnu.org>
152 Instead of providing a system or portable file writer with a raw
153 case in the format needed for output, provide it with a regular
154 case. The writer takes care of any needed translation.
156 * aggregate.c: Adopt new scheme for AGGREGATE.
157 (struct agr_proc) sfm_agr_case member removed.
158 (write_case_to_sfm) Removed because the new interface is easier to
161 * get.c: Adopt new scheme for SAVE, XSAVE, EXPORT.
163 * pfm-write.c: Implement new scheme.
165 * sfm-write.c: Ditto.
167 Mon Nov 15 00:32:24 2004 Ben Pfaff <blp@gnu.org>
169 Instead of treating `struct file_handle' as a class to subclass
170 into data files, system files, and portable files, instead use it
171 as a helper that coordinates access. Now it is opaque, too.
173 This means that most references to a struct file_handle are now
174 changed into references to one of struct dfm_reader, struct
175 dfm_writer, struct sfm_reader, struct sfm_writer, struct
176 pfm_reader, or struct pfm_writer, according to what's being read
179 Most related changes are only worth summarizing briefly.
181 * dictionary.c: (dict_clear) Destroy aux data in deleted
183 (dict_clear_aux) New function.
184 (dict_create_var) Initialize aux, aux_dtor.
185 (dict_delete_var) Destroy aux data in deleted variable.
187 * file-handle.h: (struct fh_ext_class) Removed.
188 (struct file_handle) Removed.
189 (fh_init_files) Removed.
191 * file-handle.q: Changed references to a handle's `private' member
192 to direct references.
193 (struct private_file_handle) Renamed file_handle.
194 Add next, open_cnt, type, open_mode, aux members.
195 (struct file_handle_list) Removed.
196 (extern var inline_file) Removed.
197 (static var file_handles) Changed from file_handle_list * to
199 (create_file_handle) Initialize new members.
200 (fh_close_handle) Removed.
201 (mode_name) New function.
202 (fh_open) New function.
203 (fh_close) New function.
204 (fh_parse_file_handle) Renamed fh_parse().
206 * glob.c: (init_glob) Remove fh_init_files() call.
208 * aggregate.c: use sfm_writer.
209 (create_sysfile) Removed because the new interface is simpler.
211 * apply-dict.c: Use sfm_reader.
213 * data-list.c: Use dfm_reader.
215 * file-type.c: Use dfm_reader.
217 * get.c: Use sfm_reader, sfm_writer, pfm_reader, pfm_writer.
219 * inpt-pgm.c: Use dfm_reader.
221 * print.c: Use dfm_writer.
223 * sysfile-info: Use sfm_reader.
225 * dfm-read.c: Adopt new file handle infrastructure.
227 * dfm-write.c: Ditto.
231 * pfm-write.c: Ditto.
235 * sfm-write.c: Ditto.
237 Mon Nov 15 00:31:44 2004 Ben Pfaff <blp@gnu.org>
239 Break dictionary functions into separate header file.
241 * dictionary.h: New file.
243 * var.h: Moved dict_*() functions to dictionary.h.
245 Mon Nov 15 00:30:33 2004 Ben Pfaff <blp@gnu.org>
247 Get rid of procedure-specific union in struct variable, using
248 instead a void * pointer and a destructor function.
250 Most related changes are only worth brief summaries.
252 * crosstabs.q: Fix includes. Use new struct var_range in lieu of
253 old p.crs member in struct variable.
255 * frequencies.q: Fix includes. Use new struct var_freqs in lieu
256 of old p.frq member in struct variable.
258 * histogram.c: (draw_histogram) Takes new freq_tab arg because
259 it's no longer possible to grab this from var->p.frq.
261 * piechart.c: (draw_piechart) Ditto.
263 * group.c: (group_proc_get) New function.
265 * levene.c: Use group_proc_get() in lieu of old p.grp_data member
272 * main.c: (execute_command) Clear aux data in default_dict after
273 each command. (It's debatable whether this should be done.)
275 * matrix-data.c: Use new struct mxd_var in lieu of old p.mxd
276 member in struct variable.
278 * means.q: Get rid of integer mode, which is not included in
279 recent SPSS and was the only code that wanted per-variable private
282 * var.h: (struct crosstab_proc) Removed.
283 (struct frequencies_proc) Removed.
284 (struct list_proc) Removed.
285 (struct get_proc) Removed.
286 (struct means_proc) Removed.
287 (struct matrix_data_proc) Removed.
288 (struct match_files_proc) Removed.
289 (lots of enums) Removed.
290 (struct variable) Removed members `p', `get'. Add member
293 * vars-atr.c: (var_attach_aux) New function.
294 (var_detach_aux) New function.
295 (var_clear_aux) New function.
296 (var_dtor_free) New function.
297 (discard_variables) Use NULL instead of inline_file.
300 Fri Nov 12 10:07:11 WST 2004 John Darrington <john@darrington.wattle.id.au>
302 * value-labs.c Fixed the implmentation of value_to_string, so
303 that it properly handles alpha values.
305 * oneway.q Changed instances where labels were being probed manually,
306 to use the canonical {var,value}_to_string functions
308 Thu Nov 11 21:01:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
310 * examine.q cartesian.c chart.[ch] Added normal and detrended normal
311 plots. Changed the API of the cartesian plot to be a much lower level
314 Sun Nov 7 17:25:04 WST 2004 John Darrington <john@darrington.wattle.id.au>
316 * examine.q Added some of the parametric calculations
318 * factor_stats.[ch] Created
320 Sat Nov 6 21:24:31 WST 2004 John Darrington <john@darrington.wattle.id.au>
322 * examine.q Changed the definition of factors to be a composite, and
323 dealt with the consequences.
325 Sat Nov 6 20:40:38 WST 2004 John Darrington <john@darrington.wattle.id.au>
327 * examine.q Fixed problem where examine wasn't dealing properly with
330 Sat Nov 6 14:49:47 WST 2004 John Darrington <john@darrington.wattle.id.au>
332 * oneway.q Fixed problem where oneway wasn't dealing properly with
335 Thu Nov 4 11:09:01 WST 2004 John Darrington <john@darrington.wattle.id.au>
337 * q2c.c examine.q Fixed a bug (feature?) whereby arrays in the
338 command which had settings didn't get the appropriate code
341 * val.h value-labels.[ch] var-labs.c Added v*to_string functions
342 to convert variables/values to strings.
344 * examine.q Added framework for the EXAMINE command.
346 Mon Nov 1 12:46:17 WST 2004 John Darrington <john@darrington.wattle.id.au>
348 * q2c.c frequencies.q set.q t-test.q Fixed the q2c parsing of DBL
349 subcommand types. Changed frequencies.q to use it rather then the
350 custom parser. Dealt with the consequences. Added a test for NTILES
351 subcommand of frequencies.
353 Sat Oct 30 09:16:29 WST 2004 John Darrington <john@darrington.wattle.id.au>
355 * oneway.q Fixed up the behaviour when given missing values
357 * levene.c oneway.q Fixed a buglet with the levene statistic and
358 incorporated the levene test into the oneway command.
360 * group.h t-test.q Moved the CMP_EQ and CMP_LE symbols out of
361 global scope, since they're only relevant to T-TEST
363 Fri Oct 29 17:39:03 WST 2004 John Darrington <john@darrington.wattle.id.au>
365 * group.c group.h group_proc.h levene.c oneway.q t-test.q
367 Made the t-test more consistent
368 with the way it handles groups. That is, it now uses a hash instead
369 of an array of 2. Also, made the levene.c file independent of the
370 implementation of the t-test. So now levene should be fine for both
373 * Added an oneway.q file for one way anova
375 Wed Jun 2 22:08:02 2004 Ben Pfaff <blp@gnu.org>
377 * descript.c: (cmd_descriptives) Remove harmless but bogus test in
380 Mon May 31 20:45:24 2004 Ben Pfaff <blp@gnu.org>
384 * data-list.c: (cmd_data_list) Free dls->delims on lossage.
385 (data_list_trns_free) Free dls->delims.
387 * t-test.q: (tts_custom_pairs) Free vars.
388 (ssbox_one_sample_init) Fix tab_vline() argument.
389 (ssbox_independent_samples_init) Ditto.
390 (trbox_paired_init) Ditto.
391 (trbox_one_sample_init) Ditto.
393 Mon May 31 17:19:27 2004 Ben Pfaff <blp@gnu.org>
395 Generalize casefiles to the extent that we can use them for
396 sorting and other kinds of data transformations. Change cases to
397 be copy-on-write to improve memory efficiency in common cases.
398 Every access to a member of a `struct ccase' was changed to be a
399 call to a case_*() function, especially case_data(), case_num(),
400 case_str(), or case_data_rw(). Many instances of a local variable
401 named "case_num" were changed to "case_idx" as a consequence.
402 Many `struct ccase *' were changed to actual `struct ccase'
403 because of copying semantics of cases. In several places there
404 was a choice between updating debug code to work with the new ADTs
405 or just deleting it because it was useless; I chose to delete it.
407 * Makefile.am: (pspp_SOURCES) Add case.c, case.h.
413 * aggregate.c: (struct agr_proc) Change type of `sort' to
414 sort_criteria *. Add `break_vars', `break_var_cnt' members.

425 (sort_agr_to_sysfile) Removed.
427 * alloc.c: (out_of_memory) Make non-static.
429 * alloc.h: Prototype out_of_memory().
431 * casefile.c: Switched from a linked list in-memory representation
432 to a two-level array-style representation. The linked list was
433 appropriate when we could stick a header onto cases, but that's no
434 longer the case. Also, the two-level array will allow for random
435 in-memory access in case that's ever wanted. Also added the
436 concept of a `destructive casereader', one that destroys cases in
437 the underlying casefile as they are read out.
438 (macro CASES_PER_BLOCK) New macro.
439 (struct casefile) New members `value_cnt', `case_list_size',
440 `case_acct_size', `being_destroyed', `cases'. Removed `head',
442 (struct casereader) Removed `cur'. Added `destructive', `c'.
443 (global var casefiles) Made static.
444 (static var case_bytes) New var.
445 (casefile_create) Takes a value count, not a case size in bytes,
446 to conform to the case interface. All callers updated. Deal with
447 new and removed members.
448 (casefile_destroy) Deal with new and removed members.
449 (casefile_sleep) New function.
450 (casefile_get_case_size) Removed.
451 (casefile_get_value_cnt) New function.
452 (casefile_append) Rewritten to deal with new and removed members.
453 (casefile_append_xfer) New function.
454 (write_case_to_disk) Use case_serialize().
455 (call_posix_fadvise) Removed because posix_fadvise64 segfaults.
456 Couldn't figure out why.
457 (casefile_to_disk) Don't call call_posix_fadvise. Rewritten to
458 deal with new and removed members.
460 (merge_sort) Removed.
461 (casefile_sort) Removed.
462 (casefile_get_reader) Deal with new and removed members.
463 (casefile_get_destructive_reader) New function.
464 (reader_open_file) Make code more readable. Create case for
466 (casereader_get_casefile) New function.
467 (casereader_read) Deal with new and removed members. Now returns
468 a copy of the case, so that the caller is responsible for
469 destroying the returned case.
470 (casereader_read_xfer) New function.
471 (casereader_destroy) Destroy reader's case.
472 (test_casefile) Second arg is now a value count, all callers
473 updated. Now tests destructive readers too.
474 (get_random_case) Deal with new case ADT.
475 (write_random_case) Ditto.
476 (read_and_verify_random_case) Ditto.
478 * crosstabs.q: Remove debug code.

487 * expr-prs.c: Remove debug code.
489 * exprP.h: Remove debug code.
491 * flip.c: (flip_file) Use fseeko() if available.
493 * formats.c: Remove debug code.
495 * get.c: Remove debug code.
496 (struct mtf_file) Change `input' from `union value *' to `struct
497 ccase', all references updated.

501 * list.q: Remove debug code.
503 * loop.c: Remove debug code.
505 * matrix-data.c: Remove debug code.

532 (sort_active_file_in_place) New function.
533 (sort_active_file_to_casefile) New function.
534 (parse_sort) Renamed sort_parse_criteria(), rewritten & interface
535 changed, all callers updated.
536 (destroy_sort_cases_pgm) Renamed sort_destroy_criteria(),
537 rewritten & interface changed, all callers updated.
538 (sort_cases) Renamed sort_execute(), rewritten & interface
539 changed, all callers updated.
540 (struct internal_sort) Removed.
541 (do_internal_sort) Rewritten, interface changed.
542 (destroy_internal_sort) Removed.
543 (compare_case_dblptrs) Use sort_criteria instead of sort_case_pgm.
544 (struct initial_run) Removed; an initial run is now just a
546 (compare_initial_runs) Rewritten.
547 (struct external_sort) Changed almost completely.

564 (struct initial_run_state) Remove `idx_to_fv', `free_list',
565 `file_idx', `output_file'. Add `run', casefile'. Change
566 `last_output' from `struct case_list *' to `struct ccase'.
567 (write_initial_runs) Change interface, rewrite.
568 (sort_sink_write) Renamed process_case(), changed interfaced,

753 (casefile_to_disk) Use call_posix_fadvise().
754 (reader_open_file) Ditto.

795 Mon Apr 26 22:40:07 2004 Ben Pfaff <blp@gnu.org>
797 We're abusing the current ASCII driver by telling it to allocate a
798 9999-line, 9999-character page in the tests. This causes some
799 systems to curl up and die because it allocates 20 MB of
800 contiguous RAM. This change alleviates at least part of the
801 problem. It is mostly a stop-gap until the new output system is
804 * ascii.c: (struct line) New structure.

825 Fri Apr 16 23:59:51 2004 Ben Pfaff <blp@gnu.org>

839 avoid subtracting huge numbers from huge numbers, on Michael
842 Sun Apr 11 14:22:12 2004 Ben Pfaff <blp@gnu.org>
844 Rework moments routines for improved numerical stability based on
845 Michael Kiefte's advice. Any bugs or remaining numerical problems
846 are still mine though.
848 There is now a struct moments1 for use with one-pass moments. It
849 uses a provisional means algorithm as an attempt to improve
850 accuracy of higher moments. The older struct moments now only
851 handles two-pass moments.
853 * aggregate.c: Use moments1 instead moments.
855 * descript.c: Revert previous change, which is no longer needed
856 due to the moments revision.

860 (moments_pass_one) Only accumulate weights bigger than zero.
861 (moments_calculate) Allow calculating the mean on pass one, others
862 require pass two. Implement in terms of calc_moments().

864 (init_moments1) New function.
865 (moments1_clear) Ditto.
866 (moments1_create) Ditto.

881 * descript.c (calc_descriptives): Fix assert failure when only
882 MOMENT_MEAN is needed.
884 2004-04-09 Michael Kiefte <mkiefte@dal.ca>
888 fixed problem with parsing in match_statistic() causing
889 "DESCRIPTIVE STAT=MEAN." to barf.
891 "MEAN" is now default if "SORT" given without specification.
893 Fixed infinite loop with "DESCRIPT GIBBERISH=ALL." Parsing is
894 generally less forgiving of syntax errors: better to have it do
895 nothing and type it in again then to not know what it actually did
898 z-score transformation now checks score for user-missing values
899 and checks std_dev for SYSMIS.
901 2004-04-06 Michael Kiefte <mkiefte@dal.ca>
903 * aggregate.c, crosstabs.q, descript.c, dictionary.c, frequencies.q, levene.c, t-test.q, var.h:

955 Tue Mar 30 22:04:19 2004 Ben Pfaff <blp@gnu.org>
957 * vfm.c: Had to get last call to multipass_split_output() inside
958 open_active_file()/close_active_file() pairing, so introduce new
960 (internal_procedure) Move procedure() code here, except for calls
961 to open_active_file() and close_active_file().

995 nonterm_node's n earlier.
996 (generic_str_func) Ditto.
998 Mon Mar 29 15:32:17 2004 Ben Pfaff <blp@gnu.org>
1000 Add support for multipass procedures. Rewrite DESCRIPTIVES to
1001 test multipass support, take advantage of new moments

1331 Sat Mar 20 15:18:16 2004 Ben Pfaff <blp@gnu.org>
1333 Changed DFM from open-at-first-access to explicit-open. Before,
1334 calling dfm_get_record() or dfm_put_record() would automatically
1335 open the file. Now, you have to call dfm_open_for_reading() or

1453 Fixed cmd_parse() so that it always skips past a full command
1454 name. A few special commands for which this would be bad get
1455 special treatment. This lets us drop code for skipping past the
1456 end of a command name in most cmd_*() functions. It's not worth
1457 listing all the commands affected.
1459 * command.c: (struct command) Remove `cmd' member, replace by

1520 Added a handler for SIGWINCH so that viewlength and viewwidth follow
1521 changes as the window size is changed.
1523 Added fallback to set viewlength and viewwidth from LINES and COLUMS
1524 environment variables if other methods are not available.
1526 glob.c: Removed a lot of global variables from glob.c and encapsulated

2731 NO_RETURN or PRINTF_FORMAT instead.
2733 * alloc.h: Move definitions for local_alloc(), local_free() here
2734 from ../pref.h.orig and simplify.

2819 so much, by adding a "device-independent" output driver. The idea
2820 is to write out only a single output stream, then use separate
2821 processes to translate them into whatever formats we want. This
2822 is similar to how "groff" works with its various output drivers
2823 (grops, grotty, grodvi, ...).

2849 * Removed bletcherous alloca() workarounds for AIX from top of

3182 (dict_get_vars) New function, replaces fill_all_vars().

3184 drops `type' parameter, using a zero `width' to designate numeric.
3185 (dict_clone_var) New, replaces dup_variable().
3186 (dict_rename_var) New, replaces rename_variable().
3187 (dict_lookup_var) New, replaces find_variable(),

3223 calling dict_destroy().
3225 * data-list.c: (dls_var_spec) Remove `type' member, replace by

3248 * title.c: (add_document_line) Use dict_get_documents(),
3249 dict_set_documents().
3251 * vars-atr.c: (discard_variables) Use dict_clear(default_dict),

3253 there's no need for that by hand.

3256 earlier, so that we can do the compaction as a single step using
3257 dict_compact_values(). Use dict_clear_vectors().

3274 * aggregate.c: Eliminate separation of weighted and unweighted
3275 case. It made the code too obscure and I doubt it was actually
3276 faster. Instead, all code uses the "weighted" code, because
3277 that's a generalization of the "unweighted" code.
3280 (parse_aggregate_functions) No need to set FWEIGHT.
3281 (accumulate_aggregate_info) Get rid of FWEIGHT cases.
3282 (dump_aggregate_info) Ditto.

3289 (aggregate_single_case) Don't use approx_ne().

3893 Fri Dec 12 13:31:58 2003 Ben Pfaff <blp@gnu.org>

3957 enumerals, rather than a magic value. This meant that all
3958 commands had to be modified, and they were.
3959 (figure_out_command) New function.
3961 * command.def: Add CORRELATIONS, PEARSON CORRELATIONS. Add
3962 #defines for INIT, INPU, etc.

4562 Thu Jun 3 18:40:42 1999 Ben Pfaff <blp@gnu.org>
4564 Using alphanumeric variables in functions under AGGREGATE
4565 segfaulted. Fixed. Thanks to Dr. Dirk Melcher
4566 <BZN-mdksh@t-online.de> for reporting this bug.
4568 * aggregate.c: (parse_aggregate_functions) When setting the
4569 FSTRING bit, also allocate memory for the `string' member of
4571 (free_aggregate_functions) Free iter->string. Don't use the
4572 non-function bits when indexing the array of functions.
4573 [DEBUGGING] (debug_print) Don't use the non-function bits when
4574 indexing the array of functions.
4576 Sun May 30 00:00:54 1999 Ben Pfaff <blp@gnu.org>
4578 Under certain circumstances, the final case would be omitted from
4579 the results of an AGGREGATE operation. Fixed. Thanks to Dr. Dirk
4580 Melcher <BZN-mdksh@t-online.de> for reporting this bug.
4582 * aggregate.c (agr_00x_end_func): Increment number of cases in
4583 sink before writing case. For streams that keep track of how many
4584 cases there are based on this value, this means that the last case
4585 will be read in on the next stream read.
4587 Sat May 29 22:03:31 1999 Ben Pfaff <blp@gnu.org>
4589 Undefined behavior was invoked by referencing a freed pointer.
4591 * vfm.c (memory_stream_write): Free pointer *after* checking for
4594 Sat May 29 22:02:22 1999 Ben Pfaff <blp@gnu.org>
4596 A wrong record size was displayed when paging the active file to
4599 * vfm.c: (memory_stream_write) Fix off-by-one error.
4601 Sat May 29 21:50:26 1999 Ben Pfaff <blp@gnu.org>
4603 Not having enough temporary space for sorting caused a core dump.
4606 * sort.c: (allocate_cases) Initialize i.
4608 Sat May 29 21:40:54 1999 Ben Pfaff <blp@gnu.org>
4610 Syntax errors in function descriptions on AGGREGATE caused core
4613 * aggregate.c (cmd_aggregate): Don't free agr_dict after calling
4614 free_aggregate_functions(), since that function already frees
4617 Sat May 29 21:06:10 1999 Ben Pfaff <blp@gnu.org>
4619 A null pointer was dereferenced, causing a core dump, when
4620 PERCENTILES was specified on FREQUENCIES. This fixes the problem,
4621 but PSPP still doesn't calculate percentiles. Thanks to Regnor
4622 Jernsletten <rjernsle@eunet.no> for reporting this problem.
4624 * arena.c: (arena_malloc) If the arena hasn't been initialized
4625 already, initialize it.
4627 Sat May 29 20:47:29 1999 Ben Pfaff <blp@gnu.org>
4629 * Makefile.cygwin: New file supplied by Hankin <hankin@dunno.com>
4630 for compilation with Cygnus Windows B20. Not used by other
4633 Sat May 29 20:36:04 1999 Ben Pfaff <blp@gnu.org>
4635 SORT always sorted in ascending order. Fixed. Thanks to Dr. Dirk
4636 Melcher <BZN-mdksh@t-online.de> for reporting this bug.
4638 * sort.c: (compare_case_lists) Reverse sense of comparison if
4639 sorting in descending order.
4640 (compare_record) Ditto.
4642 Tue Mar 9 13:18:54 1999 Ben Pfaff <blp@gnu.org>
4644 SPLIT FILE with a string variable caused a core dump. Fixed.
4646 * vfm.c: If the variable is a string then make a temporary value
4647 struct pointing to it. The underlying problem is a lot bigger
4648 than this (see TODO) but this is a stopgap for the simple case at
4651 Tue Mar 9 13:15:53 1999 Ben Pfaff <blp@gnu.org>
4653 Nested INCLUDEs didn't work. Fixed.
4655 * getline.c: (getl_include) Set first_line to NULL in allocated
4658 Tue Mar 9 13:13:46 1999 Ben Pfaff <blp@gnu.org>
4660 The MATCH FILES procedure set the values of variables not present
4661 to 0. It should have been SYSMIS. This is now fixed.
4663 * get.c: (mtf_delete_file_in_place) Replace 0.0 by SYSMIS.
4665 Tue Mar 9 12:52:23 1999 Ben Pfaff <blp@gnu.org>
4667 The REMARK command was too aggressive about skipping lines. It
4668 didn't like being the last command in a file.
4670 * command.c: (cmd_remark) Call get_entire_line() instead of
4673 Tue Mar 9 12:48:05 1999 Ben Pfaff <blp@gnu.org>
4675 Comment parsing wasn't consistent with the rest of the code in its
4676 idea of where one command ends and another starts. This meant
4677 that sometimes commands would be mysteriously ignored. Thanks to
4678 Dr. Dirk Melcher <BZN-mdksh@t-online.de> for reporting this bug.
4680 * command.c: (parse_cmd) Hand off comment parsing to new function
4681 skip_comment() in lexer.c.
4682 * lexer.c: (skip_comment) New function.
4684 Wed Jan 20 20:22:07 1999 Ben Pfaff <blp@gnu.org>
4686 The TABLE subcommand on MATCH FILES worked only erratically at
4687 best. This fixes it. Thanks to Dr. Dirk Melcher
4688 <BZN-mdksh@t-online.de> for reporting this bug.
4690 * get.c: (mtf_compare_BY_values) When comparing string values, a
4691 difference of 1 is still a difference :-)
4692 (mtf_processing) Inverted TABLE reading logic fixed. Also don't
4693 advance TABLE files automatically when matched. Comment fixes.
4695 Tue Jan 19 22:32:31 1999 Ben Pfaff <blp@gnu.org>
4697 VARIABLE LABELS rejected a slash before the first variable
4698 specification, contradicting the documentation. Thanks to Walter
4699 M. Gray <graywm@northernc.on.ca> for reporting this bug.
4701 * var-labs.c: (cmd_variable_labels) Ignore a leading slash in
4702 command specification.
4704 Tue Jan 19 22:29:54 1999 Ben Pfaff <blp@gnu.org>
4706 Because of an incorrect optimization in memory allocation,
4707 CROSSTABS sometimes segfaulted when asked to output multiple
4708 tables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
4711 * crosstabs.q: (postcalc) New variables maxcols, maxcells, which
4712 are passed to output_pivot_table() for its use.
4713 (output_pivot_table) Instead of assuming the number of columns is
4714 constant, keep track with maxcols. In general mode, use maxcells
4715 to determine whether more matrix cells need to be allocated.
4717 Tue Jan 19 22:27:46 1999 Ben Pfaff <blp@gnu.org>
4719 CROSSTABS didn't display value labels for column and row
4720 variables. Thanks to Walter M. Gray <graywm@northernc.on.ca> for
4723 * crosstabs.q: (table_value_missing) If the specified value has a
4724 value label for this variable, then show it instead of the raw
4726 (display_dimensions) Delegate display of value_labels to
4727 table_value_missing.
4729 Mon Jan 18 20:04:06 1999 Ben Pfaff <blp@gnu.org>
4731 WRITE didn't write line ends. Fixed. Thanks to Dr. Dirk Melcher
4732 <BZN-mdksh@t-online.de> for reporting this bug.
4734 * print.c: (print_trns_proc) Write (CR/)LF if PRINT is used _or_
4735 if the file isn't declared as binary.
4737 Mon Jan 18 19:56:45 1999 Ben Pfaff <blp@gnu.org>
4739 MATCH FILES corrupted memory and dumped core on some syntax
4742 * get.c: (cmd_match_files) Set file->handle to NULL before
4744 (mtf_free_file) Don't free a null dictionary.
4746 Mon Jan 18 19:27:57 1999 Ben Pfaff <blp@gnu.org>
4748 MATCH FILES should set numeric values not available to the
4749 system-missing value, not to 0. Thanks to Dr. Dirk Melcher
4750 <BZN-mdksh@t-online.de> for reporting this bug.
4752 * get.c: (mtf_processing) Set unused records to system-missing,
4755 Mon Jan 18 15:06:46 1999 Ben Pfaff <blp@gnu.org>
4757 KEEP didn't work properly on the SAVE procedure. Fixed. Thanks
4758 to Ralf Geschke <ralf@kuerbis.org> for reporting this bug.
4760 * temporary.c: (save_dictionary) Initialize var_by_name AVL tree
4761 in newly created dictionary, and add each copied variable to the
4764 Mon Jan 18 15:04:48 1999 Ben Pfaff <blp@gnu.org>
4768 * get.c: (trim_dictionary) Free variable list for KEEP after
4771 Mon Jan 18 12:57:36 1999 Ben Pfaff <blp@gnu.org>
4773 Some systems didn't like the way open_file was coded. Thanks to
4774 Hankin <hankin@rogue.consultco.com> for pointing this out.
4776 * filename.c: (open_file) Don't try to store stdin, stdout,
4777 stderr as part of an array, because that doesn't always work.
4779 Mon Jan 18 12:53:27 1999 Ben Pfaff <blp@gnu.org>
4781 The SAVE procedure didn't save long string variables properly.
4782 Fixed by this patch. Thanks to Hankin
4783 <hankin@rogue.consultco.com> for this patch.
4785 * sfm-write.c: (write_variable) Fix off-by-one error in writing
4786 out variable pad records.
4788 Tue Jan 5 14:29:27 1999 Ben Pfaff <blp@gnu.org>
4790 Previously, if PRINT SPACE were given a negative argument, it
4791 would report an error, then spin in an (almost) infinite loop.
4792 This fixes that behavior.
4794 * print.c: (print_space_trns_proc) After reporting a negative
4795 argument, set number of lines to print to 1.
4797 Tue Jan 5 13:59:55 1999 Ben Pfaff <blp@gnu.org>
4799 SPSS 8.0 outputs some new record types in its system files, and it
4800 allows longer value labels. Accept these system files.
4802 * sfm-read.c: (sfm_read_dictionary) Ignore record type 7 subtype
4803 11 emitted by SPSS 8.0.
4805 Tue Jan 5 13:55:50 1999 Ben Pfaff <blp@gnu.org>
4807 The LIST procedure was too conservative in allocating space for
4808 buffers, which caused a bug that only showed up with very long
4809 output variables. Thanks to Hankin <hankin@dunno.com> for this
4812 * list.q: (determine_layout) Allocate 1022 bytes instead of 256.
4814 Tue Jan 5 13:34:34 1999 Ben Pfaff <blp@gnu.org>
4816 Typo meant string format specifiers weren't checked properly. I
4817 think that Hankin <hankin@dunno.com> sent me this report, but I'm
4818 willing to be corrected on this point.
4820 * format.c: (check_string_specifier) Fix obvious typo.
4822 Tue Jan 5 12:50:42 1999 Ben Pfaff <blp@gnu.org>
4824 Using $CASENUM in an expression didn't work. Here's a fix.
4825 Thanks to Dirk Melcher <BZN-mdksh@t-online.de> for reporting this
4828 * expr-evl.c: (evaluate_expression) Add OP_CASENUM case.
4830 * expr-opt.c: (dump_node) OP_CASENUM is acceptable.
4832 Tue Jan 5 12:47:48 1999 Ben Pfaff <blp@gnu.org>
4834 The changes in 0.2.1 to fix DATA LIST FREE parsing broke some
4835 other behavior, *sigh*. This patch hopefully fixes that. This
4836 time I've actually tested it.
4838 Thanks to Hankin <hankin@dunno.com> for reporting this bug.
4840 * data-list.c: (read_from_data_list_free,
4841 read_from_data_list_list) Call parse_string_as_format() directly
4842 without mucking around with the field width.
4844 Tue Jan 5 12:31:19 1999 Ben Pfaff <blp@gnu.org>
4846 Occasionally, you may encounter a script that wants to be
4847 interpreted in interactive mode. Make -i emulate this behavior to
4848 allow such scripts to be executed with PSPP.
4850 Thanks to Hankin <hankin@dunno.com> for reporting this behavior.
4852 * cmdline.c: (pre_syntax_message[]) Update -i description.
4854 * lexer.c: (preprocess_line) When getl_interactive is 2 (i.e.,
4855 when -i is given on the command line) don't treat unindented lines
4856 as starting a new command.
4858 Tue Jan 5 12:30:10 1999 Ben Pfaff <blp@gnu.org>
4860 In conjunction with egcs 1.1.1, Checker emits some bogus warnings,
4861 mostly caused by local initialized aggregates. After egcs is
4862 fixed upstream these can be removed, but for now they're not a big
4865 * ascii.c: (ascii_postopen_driver) Checker chokes on local
4866 initialized arrays. Avoid this.
4868 * sfm-write.c: (sfm_write_dictionary) Don't use a local
4871 Tue Jan 5 12:07:24 1999 Ben Pfaff <blp@gnu.org>
4873 egcs 1.1.1 has some new warnings relative to gcc 2.8.1, which the
4874 following changes avoid. Currently I compile sources with egcs
4875 1.1.1 and gcc 2.7.2.3 before sending them out.
4877 * apply-dict.c: (apply_dict) Use new avl_traverser_init() macro.
4879 * ascii.c: (option_tab[]) Initialize all struct members.
4881 * avl.h: (avl_traverser_init) New macro.
4883 * command.c: (DEFCMD, UNIMPL macros, cmd_table[]) Initialize all
4886 * crosstabs.q: (enum_var_values) Use new hsh_iterator_init()
4889 * hash.c: Comment fix.
4891 * hash.h: (hsh_iterator_init) New macro.
4893 * html.c: (option_tab[]) Initialize all struct members.
4895 * pfm-write.c: (write_value_labels) Use new avl_traverser_init()
4898 * postscript.c: (option_tab[]) Initialize all struct members.
4899 (output_encodings, preclose, dump_lines) Use new
4900 hsh_iterator_init() macro.
4902 * sfm-write.c: (write_value_labels) Use new avl_traverser_init()
4905 * sysfile-info.c: (describe_variable) Use new avl_traverser_init()
4908 Thu Nov 19 12:32:45 1998 Ben Pfaff <blp@gnu.org>
4910 * data-in.c: Examined each of the parsing functions to make sure
4911 that they wouldn't dump core if they were passed a string of the
4912 wrong length, since now the DATA LIST FREE/LIST routines don't
4913 check for field width before passing it to the data parser.
4914 (parse_RBHEX, parse_AHEX) Reject odd length input.
4915 (parse_string_as_format) Reject input that's too short or too
4918 * data-list.c: Before, the DATA LIST FREE/LIST routines would pad
4919 a field to its entire declared output width then pass it to the
4920 data-in parsing routines. This contradicted the documented
4921 behavior. This is fixed in these changes. Thanks to Mark H. Wood
4922 <mwood@IUPUI.Edu>. In addition, this fixes a few more details of
4923 free-format parsing that differed from SPSS.
4924 (cut_field) Commas and spaces are treated identically. Returns
4925 the proper column instead of a fixed 1 value.
4926 (parse_field) Removed.
4927 (read_from_data_list_free, read_from_data_list_list) Call
4928 parse_string_as_format directly instead of parse_field.
4930 * heap.c: (heap_delete) Stylistic fixes.
4932 Sun Aug 9 11:12:13 1998 Ben Pfaff <blp@gnu.org>
4934 * loop.c: (loop_2_trns_proc) Formatting fix.
4936 * sel-if.c: (cmd_filter) Set FILTER_before_TEMPORARY.
4938 * var.h: (glob var FILTER_before_TEMPORARY) New global var.
4940 * vfm.c: (macro FILTERED) New.
4941 (static var filter_var) New.
4942 (process_active_file_write_case) Use FILTERED.
4943 (setup_filter) Set filter_var.
4944 (close_active_file) Delete the filter if not
4945 FILTER_before_TEMPORARY.
4946 (procedure_write_case) Use FILTERED.
4948 Sat Aug 8 00:20:14 1998 Ben Pfaff <blp@gnu.org>
4950 * crosstabs.q: Changed /PIVOT={ON,OFF} to /FORMAT={PIVOT,NOPIVOT}.
4952 * data-in.c: (parse_day_count) Message fix.
4953 (parse_month) Style fix.
4955 * data-list.c: (struct data_list_pgm) New member eof.
4956 (cmd_data_list) Init eof to 0.
4957 (do_reading) Implement the /END subcommand and read-past-eof
4960 * do-if.c: Include stdio.h when debugging.
4961 (cmd_else_if) Make sure the command is .-terminated.
4963 * glob.c: (init_glob) Capitalize the command prompt.
4965 * inpt-pgm.c: (end_case_trns_proc) Debugging message.
4966 (end_file_trns_proc) Debugging message.
4968 * loop.c: (internal_cmd_loop) Make it work when there's no loop
4970 (loop_2_trns_proc) Enable MXLOOPS (why was this disabled?)
4972 * main.c: (dump_token) Make kwtab[] const.
4974 * set.q: Spelling, comment fixes.
4976 * sysfile-info.c: (cmd_display) DISPLAY VECTORS not DISPLAY
4979 * vars-prs.c: (fill_all_vars) Style fix.
4981 * vfm.c: (index_to_varname) Return const.
4983 Tue Aug 4 23:49:23 1998 Ben Pfaff <blp@gnu.org>
4985 * Changes in many source files for partial -ansi -pedantic and
4986 no-debugging compliance: Remove trailing common in enum
4987 declarations; add `unused' attributes; insert some appropriate
4990 * cmdline.c: (parse_command_line) Add new --testing-mode flag.
4992 * command.c: (shell) Make static.
4993 (run_command) Make static.
4995 * data-list.c: (dump_fixed_table) Remove use of local_strdup().
4997 * dfm.c: (cmd_begin_data) I18n fix.
4999 * error.c: (verbose_msg) Define if __STRICT_ANSI__.
5001 * error.h: (macro verbose_msg) Define if __STRICT_ANSI__.
5003 * expr-opt.c: (evaluate_tree) Don't initialize local arrays if
5006 * file-handle.q: Don't prepend the source file directory name to
5007 the data file name. (Ongoing issue.)
5008 (prepend_current_directory) Comment out.
5009 (internal_cmd_file_handle) Don't call prepend_current_directory().
5010 (fh_get_handle_by_filename) Ditto.
5012 * filename.c: Append zero byte to readlink() return value.
5014 * getline.c: (getl_read_line) I18n fix.
5016 * lexer.h: Don't use gcc features if __STRICT_ANSI__.
5018 * misc.h: Don't use gcc features if __STRICT_ANSI__.
5020 * pfm-write.c: (bufwrite) Don't try to increment a void * pointer
5023 * postscript.c: (output_encodings) Don't use local_strdup().
5026 * print.c: Don't use gcc features if __STRICT_ANSI__.
5028 * q2c.c: (dump_vars) Don't put a , at the end of the last enum.
5030 * recode.c: (parse_src_spec) Fully brace nested if's.
5032 * set.q: (global var set_testing_mode) New var.
5034 Wed Jul 29 22:01:44 1998 Ben Pfaff <blp@gnu.org>
5036 * ascii.c: Add some more `unused' attributes that only come into
5037 play when NDEBUG is defined.
5038 (ascii_close_page) Set s_len when reallocating s.
5040 * crosstabs.q: (delete_missing) New function.
5041 (output_pivot_table) Call delete_missing() if /MISSING=REPORT.
5042 (make_summary_table) Create summary table reallocable.
5044 * postscript.c: Add more `unused' attributes as above.

5049 * tab.h: (struct tab_table) [GLOBAL_DEBUGGING] New `reallocable'
5052 * var.h: (macro force_dup_variable) [!GLOBAL_DEBUGGING] Remove
5053 gratuitous space between parameter definition.
5055 * vars-atr.c: Changed some assert(0)'s to abort()'s to prevent
5056 complaints about running off the end of functions with NDEBUG
5059 Sun Jul 5 00:17:25 1998 Ben Pfaff <blp@gnu.org>
5061 * Several source files: Removed some PORTME notes when reflection
5062 revealed that ANSI forbids that sort of breakage. Also, added
5063 lots of `unused' qualifiers here and there.

8234 `long_options' array definition.
8235 (pre_syntax_message) Fixes.

8298 (static var ps_fontmaps) Removed.
8300 (ps_init_driver) Removed obsolete references, updated.
8301 Initializes `translate_x', `translate_y', `scale'. Doesn't read
8302 fontmap, of course. Refers to font names through internal_name
8303 rather than subversive means. Frees proper items.
8304 (static var option_tab[]) Removed `fontmap-file' option; renamed
8305 `fixed-font', `prop-font'.
8306 (ps_option) Corresponds to option_tab[].
8307 (read_fontmap, release_fontmap, ps_to_dit, compare_ps2dit,
8308 hash_ps2dit, compare_dit2family, hash_dit2family, compare_family,
8309 hash_family) Removed.

8311 PostScript font name properly. New prologue file comment `!!!'
8313 (ps_open_page) Adds translate_x, translate_y to BP prologue
8314 function; gives SF argument floating-point format.
8315 (ps_text_set_font_by_name) Doesn't try to map PostScript->Groff
8316 font name. Doesn't change font family.
8317 (ps_text_set_font_by_position) Generates Groff font name from font
8318 family name instead of through table lookup.
8319 (ps_text_set_font_by_family) Renamed `ps_text_set_font_family',
8320 all references changed. Reduced to simple string assignment.
8321 (ps_get_font_name) Removed.
8322 (ps_get_font_family) Reduced to string return.
8323 (text) Doesn't save `position' since it no longer exists. Ugly
8324 kluge to save font family--fix soon?
8325 (load_font) Removed PostScript name argument.

8343 of comments in script files. Now more liberal on criteria for
8344 performing a state transition--if *anything* happened correctly,
8345 not just if *everything* happened correctly.
8347 * data-out.c: (convert_F) Comment fix. Why in the fsck does
8348 Checker segfault on formatting large numbers and why in the fsck
8349 hadn't I noticed this before?
8351 * expr.h, exprP.h: No longer turn off GLOBAL_DEBUGGING.
8353 * list.q: (cmd_list) Commented out the actual output routine
8354 because of various problems. Probably will abandon the idea of
8355 using the general `crushed tables' for the LIST procedure.
8357 * temporary.c: (restore_dictionary) Sets var_by_name to NULL after
8358 clearing it. Allocates a new var_by_name dictionary before trying
8359 to add members to it.
8361 * vars-atr.c: [DEBUGGING] (dump_one_var_node) Removed argument
8362 `sib'. Changed type of `node' argument.
8363 [DEBUGGING] (dump_var_tree) Replaced avlwalk() with
8365 (clear_variable) Only dumps the var tree if var_by_name non-NULL.
8366 [DEBUGGING] Only deletes the variable from var_by_name if that var

8458 FSF address; reformatted to better conform to GNU standards;
8459 comment fixes. Added markups to prevent GNU indent from messing
8460 up my beautiful formatting :-).
8462 * q2c.c: (get_line) Ignores lines that begin with `/* *INDENT' so
8463 that GNU indent markups can be passed through without problems.

8485 calculate `min_n', `max_degree'.
8486 (postcalc) Passes new arg to dump_statistics().
8487 (dump_full) Honor NOLABEL option. Buggy? Adds variable name
8489 (dump_condensed) Adds variable name title.
8490 (sum_freqs) Removed.

8534 * descript.g: Removed; merged into `descript.q'.
8536 * expr-evl.c: (evaluate_expression) Now returns a double. For
8537 numeric results, it returns the result as well as storing it in
8538 the passed `value' structure if non-NULL. For string results it
8539 just returns 0.0 and it must be passed non-NULL. Many references
8540 to this function were optimized by use of this change, especially
8541 but not exclusively in `compute.c'.
8543 * frequencies.g: Comment fix.
8545 * glob.c: (glob var process_if_expr) New global var.

8559 and write the number of cases in its proper slot.
8561 * som-frnt.c: (som_insert_table) Masks off expansion options since
8562 only SOPT_X_NORM seems to work sensibly.
8564 * som-low.c: (get_cell_size) Fixed bug when a table cell was sized
8565 with a `fixed' value of 2.
8567 * sort.c: (cmd_sort_cases) Cancels PROCESS IF.

8585 * sysfile-info.c: (cmd_sysfile_info) When adjusting table size,
8586 doesn't have to take into account number of value labels since
8587 they're in a subtable anyway. Also, doesn't display more than 10
8588 value labels since we can't yet break pages in subtables.
8590 Tue Feb 4 15:15:50 1997 Ben Pfaff <blp@gnu.org>
8592 * som-frnt.c: (som_change_table_size) Simple change for elegance
8593 that shouldn't change behavior.
8594 (som_set_value) Comment fix.
8596 * som-high.c: (som_submit_table) Message fix.

8624 * sfm.h: (struct sfm_read_info) New struct for use by
8625 sfm_read_dictionary().
8627 * som-frnt.c: (som_create_table) New argument CREATE_FLAGS,
8628 currently used just for tables that can be dynamically resized and
8629 thus have to be allocated with arena_malloc() instead of

8900 (output_record) Removed debug code.
8901 (merge) Added code to close all the input files that are currently
8902 open. This is a likely location for bugs, because I'm not sure
8903 about boundary conditions. Removed an unnecesary heap_delete().
8904 (merge_once) Removed input file "optimization" that in fact
8905 screwed up the rest of the code. Message and comment fixes.

10665 Sun Jul 14 15:45:31 1996 Ben Pfaff <blp@gnu.org>
10667 * Many more changes to som.c especially, but these will not be
10668 documented as I have resolved to remove them. This patchlevel is
10669 being released solely so that I can fall back to it if I decide
10670 that removing the changes is not a good idea.
10672 Sat Jul 13 09:58:44 1996 Ben Pfaff <blp@gnu.org>
10674 * som.c: (global var som) New member `cum_y'.

10720 (convert_F) Comment fix. Now won't print `-.000', etc.

10739 frequencies.q, list.q, vars-prs.c, vfm.c: Removed reference to
10740 HAVE_MALLOC_H because Borland C++ alloca() is broken, so why
10741 include the corresponding header?

10775 * Thanks to an unreliable IDE hard drive, I have spent the last
10776 day reconstructing my Debian GNU/Linux installation and redoing
10777 the previous day's changes--somehow I managed to save every file
10778 except for output.c and output.h. So the following changes could
10779 really be considered independent of the output.c, output.h changes
10782 * output.h, output.c: Moved the outp_configure_vec global var,
10783 outp_names struct, and enum set OUTP_S_* from output.h to output.c.
10784 outp_configure_vec is now static.
10786 Thu Jul 4 20:20:24 1996 Ben Pfaff <blp@gnu.org>
10788 * The entire philosophy behind configuration of the output drivers
10789 changed. Now there is a termcap-type configuration where drivers
10790 to be read are determined beforehand, rather than parsing the
10791 entire output init file and storing it in memory & deciding what
10792 to actually use later. Faster & more memory-efficient at the same
10795 * output.c: Comment fix. Removed outp_init_drivers global var.
10796 Removed all references to synonyms. New structure outp_defn. New
10797 global vars outp_macros, outp_configure_vec.

10807 (outp_list_classes) Bug fix, cleaned up.
10808 (outp_list_drivers) Not implemented anymore.
10809 (outp_configure_driver) Now a static function; simplified; now

10823 * cmdline.c: (parse_command_line) New option -v --verbose;
10824 --version changed to -V. --device option changed syntax to just
10825 take a single device name. Accepts key=value declaration of
10826 output init file macros. Syntax message updated.

10832 overridden by real environment vars.
10833 (search_path) Uses verbose_msg() instead of #ifdef'd printf().
10834 * filename.h: interp_environ_vars() renamed interp_vars().
10836 * error.c, error.h: Added extern variable `verbosity', message
10839 * error.c: (vmsg) Support message class MM.
10840 (verbose_msg) New function.
10842 * descript.q: (generate_z_varname) Bug fix in generation of
10844 (dump_z_table) Bug fix in column headers.
10846 * ascii.c: (ascii_init_driver) Changed minimum number of lines per
10847 page from 29 to 15. Don't set a default for ops[OPS_INIT,
10848 OPS_DONE]. Writes the uninit string when the driver is closed.
10849 (ascii_open_page) Write the init string before the first page.
10850 (output_shorts) Form of main loop changed from `while' to `for'.
10851 Bug fix with overstrikes: the character is printed *after* the
10852 backspace. Eliminated a lot of `& 0xff' modifiers.
10853 (advance_to_left_margin) New function.
10854 (return_carriage, output_lines) Handle left margin.

10879 (text_draw) No longer considers fully justified text an internal
10882 * output.h: New flag OUTP_T_VERT; other OUTP_T_ values changed.

10914 (dump_page) New arguments.
10915 (som_submit_table) Handle new variables.
