3 Bug #21111. Reviewed by John Darrington.
5 * do-if.c: Fix ELSE and ELSE IF clauses.
6 (add_clause): Drop TARGET_INDEX argument and figure out the target
7 of the jump on our own. The caller couldn't compensate for the
8 inserted BREAK transformation. Updated all callers.

12 * repeat.c (parse_numbers): Fixed bug parseing ranges vs. lists.
13 Ensured that floats are accepted in lists, but not in ranges.

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