3 * parse.c (parse_function): Accept TO in any case for use with
4 n-ary functions. Fixes bug #18923. Thanks to John Darrington for
7 Sat Dec 16 12:20:14 2006 Ben Pfaff <blp@gnu.org>
9 * operations.def: Reverse order of arguments to DATEDIFF, for
10 compatibility. Thanks to Daniel Williams
11 <Daniel.E.Williams@state.or.us> for reporting this bug.
13 Wed Dec 13 19:30:26 2006 Ben Pfaff <blp@gnu.org>
15 Implement support for DATESUM, DATEDIFF expression functions. See
18 * helpers.c (enum date_unit): New enum.
19 [!HAVE_TRUNC] (trunc): New function.
20 (recognize_unit): New function.
21 (year_diff): New function.
22 (month_diff): New function.
23 (quarter_diff): New function.
24 (date_unit_duration): New function.
25 (expr_date_difference): New function.
26 (enum date_sum_method): New function.
27 (recognize_method): New function.
28 (add_months): New function.
29 (expr_date_sum): New function.
31 * operations.def: Implement DATESUM, DATEDIFF functions. Mark
34 Sun Dec 10 16:49:33 2006 Ben Pfaff <blp@gnu.org>
36 * operations.def: Implement VALUELABEL function. Add DATEDIFF,
37 DATESUM unimplemented stubs.
39 * parse.c (type_coercion_core): Add support for OP_var type, which
40 is a name for a numeric or string variable.
41 (is_compatible) New function.
42 (check_operator) Only require values to be compatible with their
43 expected types, not identical.
44 (is_valid_node) Ditto.
45 (compare_names) Always return mismatch if the command name can't
47 (lookup_function_helper) Pass the new OPF_NO_ABBREV flag to the
50 * generate.pl (init_all_types): Add support for a type just called
51 "var" that may be a numeric or string variable name. Also, add a
52 no_abbrev option that prevents a function name from being
53 abbreviated (in case of naming conflict otherwise).
55 * parse.inc.pl: Output OPF_NO_ABBREV flag.
57 * private.h: Add OPF_NO_ABBREV flag.
59 Wed Jul 12 21:03:17 2006 Ben Pfaff <blp@gnu.org>
61 * evaluate.c (cmd_debug_evaluate): Don't try to resize a null
64 Fri Jun 9 13:59:15 2006 Ben Pfaff <blp@gnu.org>
66 Reform string library.
68 * generate.pl (init_all_types): `struct fixed_string' is now
71 Sun May 7 10:05:42 WST 2006 John Darrington <john@darrington.wattle.id.au>
73 * evaluate.c: Removed call to copy_mangle, and replaced with the
74 original buf_copy_rpad.
76 Mon May 1 15:11:48 2006 Ben Pfaff <blp@gnu.org>
78 Prohibit LAG following TEMPORARY. This both matches SPSS behavior
79 and fixes a bug: we saved the cases for LAG before TEMPORARY but
80 allowed access to variables created afterward anyhow (which could
83 * generate.pl: Parse "perm_only" flag on operations.
85 * operations.def: Add "perm_only" flag to LAG operations.
87 * parse.c: Disallow OPF_PERM_ONLY operations after TEMPORARY.
89 * parse.inc.pl: Output OPF_PERM_ONLY flag for "perm_only"
92 * private.h: Add OPF_PERM_ONLY flag.
94 Sun Apr 23 22:06:45 2006 Ben Pfaff <blp@gnu.org>
96 Continue reforming error message support. In this phase, get rid
97 of message "titles" and put the message text in `struct error'.
98 Now `struct error' encapsulates a message more properly.
100 * helpers.c: (expr_error) Use err_msg() instead of err_vmsg().
101 Format message ourselves.

105 * Moved files from src directory
