7 * Revision 1.20 1996-03-20 09:35:16 adam
8 * Function dict_lookup_grep got extra parameter, init_pos, which marks
9 * from which position in pattern approximate pattern matching should occur.
11 * Revision 1.19 1996/02/02 13:43:50 adam
12 * The public functions simply use char instead of Dict_char to represent
13 * search strings. Dict_char is used internally only.
15 * Revision 1.18 1996/02/01 20:39:52 adam
16 * Bug fix: insert didn't work on 8-bit characters due to unsigned char
17 * compares in dict_strcmp (strcmp) and signed Dict_char. Dict_char is
20 * Revision 1.17 1995/12/06 17:48:30 adam
21 * Bug fix: delete didn't work.
23 * Revision 1.16 1995/10/09 16:18:31 adam
24 * Function dict_lookup_grep got extra client data parameter.
26 * Revision 1.15 1995/09/04 12:33:31 adam
27 * Various cleanup. YAZ util used instead.
29 * Revision 1.14 1994/10/04 17:46:55 adam
30 * Function options now returns arg with error option.
32 * Revision 1.13 1994/10/04 12:08:05 adam
33 * Some bug fixes and some optimizations.
35 * Revision 1.12 1994/10/03 17:23:03 adam
36 * First version of dictionary lookup with regular expressions and errors.
38 * Revision 1.11 1994/09/28 13:07:09 adam
39 * Use log_mask_str now.
41 * Revision 1.10 1994/09/26 10:17:24 adam
44 * Revision 1.9 1994/09/22 14:43:56 adam
45 * First functional version of lookup with error correction. A 'range'
46 * specified the maximum number of insertions+deletions+substitutions.
48 * Revision 1.8 1994/09/22 10:43:44 adam
49 * Two versions of depend. Type 1 is the tail-type compatible with
50 * all make programs. Type 2 is the GNU make with include facility.
51 * Type 2 is default. depend rule chooses current rule.
53 * Revision 1.7 1994/09/19 16:34:26 adam
54 * Depend rule change. Minor changes in dicttest.c
56 * Revision 1.6 1994/09/16 15:39:12 adam
57 * Initial code of lookup - not tested yet.
59 * Revision 1.5 1994/09/06 13:05:14 adam
60 * Further development of insertion. Some special cases are
61 * not properly handled yet! assert(0) are put here. The
62 * binary search in each page definitely reduce usr CPU.
64 * Revision 1.4 1994/09/01 17:49:37 adam
65 * Removed stupid line. Work on insertion in dictionary. Not finished yet.
67 * Revision 1.3 1994/09/01 17:44:06 adam
68 * depend include change.
70 * Revision 1.2 1994/08/18 12:40:54 adam
71 * Some development of dictionary. Not finished at all!
