5 * loop.c (loop_trns_proc): Use gsl_finite instead of finite, , as
6 a stopgap measure for portability until appropriate gnulib modules
9 2007-09-23 Ben Pfaff <blp@gnu.org>
11 Bug #21111. Reviewed by John Darrington.
13 * do-if.c: Fix ELSE and ELSE IF clauses.
14 (add_clause): Drop TARGET_INDEX argument and figure out the target
15 of the jump on our own. The caller couldn't compensate for the
16 inserted BREAK transformation. Updated all callers.

20 * repeat.c (parse_numbers): Fixed bug parseing ranges vs. lists.
21 Ensured that floats are accepted in lists, but not in ranges.
23 Tue Dec 19 08:12:46 2006 Ben Pfaff <blp@gnu.org>
25 Fix LOOP. Thanks to Daniel Williams
26 <Daniel.E.Williams@state.or.us> for reporting one of the bugs
29 * loop.c (cmd_loop): Keep track of whether we created the index
30 variable and delete it if parsing fails, instead of creating it
31 after parsing the IF clause. This allows the index variable to be
32 used in the IF clause. This incidentally fixes a segfault when no
33 index variable was used. Also, return CMD_CASCADING_FAILURE if we
35 (parse_if_clause): Don't allow more than one IF clause.
36 (parse_index_clause): Don't allow more than one index clause.
37 Create the index variable if it doesn't exist.
38 (end_loop_trns_proc): Invert the sense of END LOOP's IF clause.
40 Sat Dec 9 20:12:34 2006 Ben Pfaff <blp@gnu.org>
42 * repeat.c (parse_lines): Issue an error when attempting to nest
43 DO REPEAT in compatibility mode.
45 Sat Dec 2 17:01:59 2006 Ben Pfaff <blp@gnu.org>
47 Significant cleanup to DO REPEAT.
49 * repeat.c: (struct line_list) Rename struct repeat_line. Use
50 struct ll instead of explicit "next" pointer. Make "file_name"
51 const. Change "const char *line" to "struct substring text". Add
52 `syntax' member. Update all references.
53 (enum repeat_entry_type) Rename repeat_macro_type, update all
55 (struct repeat_entry) Rename struct repeat_macro. Use struct ll
56 instead of explicit "next" pointer. Change "char[] id" to "struct
57 substring name". Change "char **replacement" to "struct substring
58 *replacements". Update all references.
59 (struct repeat_block) Use struct ll_list for lists of lines,
60 macros. Change "cur_line" to struct ll *.
61 (cmd_do_repeat) Don't bother adding an empty getl source at all.
62 This saves special-casing an empty source in repeat_read.
63 (parse_specification) Use new find_macro function.
64 (find_macro) New function.
65 (skip_indentor) Removed.
66 (recognize_keyword) Change interface, update callers.
67 (recognize_do_repeat) Ditto.
68 (recognize_end_repeat) Ditto.
69 (parse_lines) Use lex_preprocess_line to preprocess the input line
70 to check for DO REPEAT and END REPEAT, instead of coding it
72 (parse_ids) Need to make a copy of the array parsed by
73 parse_mixed_vars_pool, instead of using it verbatim, because we're
74 using struct substring now.
75 (add_replacement) Use struct substring in interface, instead of
76 const char *, and update all callers.
77 (find_substitution) Rewrite using substring, in terms of
79 (do_repeat_filter) Use struct substring to simplify code.
80 (current_line) New function.
82 Sat Dec 2 16:40:12 2006 Ben Pfaff <blp@gnu.org>
84 Fix lack of ->name and ->location in DO REPEAT's getl_interface.
87 * repeat.c: (cmd_do_repeat) Initialize name, location in
89 (do_repeat_read) Adjust semantics of cur_line so that, after the
90 call, it points to the line just returned, instead of to the next
91 line to be returned. Thus, do_repeat_name and do_repeat_location
92 can use cur_line to obtain the info they need.
93 (do_repeat_name) New function.
94 (do_repeat_location) New function.
96 Thu Nov 30 22:01:27 2006 Ben Pfaff <blp@gnu.org>
98 * repeat.c (do_repeat_read): Properly handle empty DO REPEAT...END
99 REPEAT block. Fixes bug #18407. Thanks to John Darrington for
102 Sat Oct 28 16:18:48 WST 2006 John Darrington <john@darrington.wattle.id.au>
104 * repeat.c: Eliminated references to extern variable getl_buf.
106 Sun May 7 18:18:33 2006 Ben Pfaff <blp@gnu.org>
110 * repeat.c: (parse_ids) Take pool parameter and allocate all
111 memory from pool. Reduce implementation from loop to single call
112 to parse_mixed_vars_pool().
113 (store_numeric) Removed.
114 (add_replacement) New function.
115 (parse_numbers) Take pool parameter and allocate all memory from
116 pool. Require ranges to be in increasing order.
117 (parse_strings) Take pool parameter and allocate all memory from
120 Wed May 3 22:45:41 2006 Ben Pfaff <blp@gnu.org>
122 Continue reforming procedure execution. In this phase, get rid of
123 many global variables, consolidating procedure execution in
124 procedure.c. Encapsulate transformations in new "struct
125 trns_chain". Also, change implementation of N OF CASES, FILTER,
126 and PROCESS IF from special cases to transformations.
128 * do-if.c: (cmd_do_if) Use finalizer to ensure control stack gets
130 (do_if_finalize_func) New function.
132 * loop.c: (create_loop_trns) Use finalizer to ensure control stack gets
134 (loop_trns_finalize) New function.
136 * temporary.c: (global var temporary) Removed. Changed references
137 to use proc_make_temporary_transformations_permanent() or
138 proc_in_temporary_transformations().
139 (global var temp_dict) Removed.
140 (global var temp_trns) Removed.
141 (cmd_temporary) Reimplement in terms of
142 proc_in_temporary_transformations() and
143 proc_start_temporary_transformations().
144 (cancel_temporary) Moved to procedure.c, renamed
145 proc_cancel_temporary_transformations().
147 Thu Mar 2 08:40:33 WST 2006 John Darrington <john@darrington.wattle.id.au>
149 * Moved files from src directory
