11 * parse.c (parse_function): Accept TO in any case for use with
12 n-ary functions. Fixes bug #18923. Thanks to John Darrington for
15 Sat Dec 16 12:20:14 2006 Ben Pfaff <blp@gnu.org>
17 * operations.def: Reverse order of arguments to DATEDIFF, for
18 compatibility. Thanks to Daniel Williams
19 <Daniel.E.Williams@state.or.us> for reporting this bug.

23 Implement support for DATESUM, DATEDIFF expression functions. See

27 [!HAVE_TRUNC] (trunc): New function.
28 (recognize_unit): New function.
29 (year_diff): New function.
30 (month_diff): New function.

35 (recognize_method): New function.
36 (add_months): New function.
37 (expr_date_sum): New function.
39 * operations.def: Implement DATESUM, DATEDIFF functions. Mark
42 Sun Dec 10 16:49:33 2006 Ben Pfaff <blp@gnu.org>
44 * operations.def: Implement VALUELABEL function. Add DATEDIFF,
45 DATESUM unimplemented stubs.
47 * parse.c (type_coercion_core): Add support for OP_var type, which
48 is a name for a numeric or string variable.
49 (is_compatible) New function.
50 (check_operator) Only require values to be compatible with their
51 expected types, not identical.
52 (is_valid_node) Ditto.
53 (compare_names) Always return mismatch if the command name can't
55 (lookup_function_helper) Pass the new OPF_NO_ABBREV flag to the
58 * generate.pl (init_all_types): Add support for a type just called
59 "var" that may be a numeric or string variable name. Also, add a
60 no_abbrev option that prevents a function name from being
61 abbreviated (in case of naming conflict otherwise).
63 * parse.inc.pl: Output OPF_NO_ABBREV flag.
65 * private.h: Add OPF_NO_ABBREV flag.
67 Wed Jul 12 21:03:17 2006 Ben Pfaff <blp@gnu.org>
69 * evaluate.c (cmd_debug_evaluate): Don't try to resize a null
72 Fri Jun 9 13:59:15 2006 Ben Pfaff <blp@gnu.org>
74 Reform string library.
76 * generate.pl (init_all_types): `struct fixed_string' is now
79 Sun May 7 10:05:42 WST 2006 John Darrington <john@darrington.wattle.id.au>
81 * evaluate.c: Removed call to copy_mangle, and replaced with the
82 original buf_copy_rpad.
84 Mon May 1 15:11:48 2006 Ben Pfaff <blp@gnu.org>
86 Prohibit LAG following TEMPORARY. This both matches SPSS behavior
87 and fixes a bug: we saved the cases for LAG before TEMPORARY but
88 allowed access to variables created afterward anyhow (which could
91 * generate.pl: Parse "perm_only" flag on operations.
93 * operations.def: Add "perm_only" flag to LAG operations.
95 * parse.c: Disallow OPF_PERM_ONLY operations after TEMPORARY.
97 * parse.inc.pl: Output OPF_PERM_ONLY flag for "perm_only"
100 * private.h: Add OPF_PERM_ONLY flag.
102 Sun Apr 23 22:06:45 2006 Ben Pfaff <blp@gnu.org>
104 Continue reforming error message support. In this phase, get rid
105 of message "titles" and put the message text in `struct error'.
106 Now `struct error' encapsulates a message more properly.
108 * helpers.c: (expr_error) Use err_msg() instead of err_vmsg().
109 Format message ourselves.
