2008-05-15 Ben Pfaff Patch #6512. * loop.c (loop_trns_proc): Use gsl_finite instead of finite, , as a stopgap measure for portability until appropriate gnulib modules are available. 2007-09-23 Ben Pfaff Bug #21111. Reviewed by John Darrington. * do-if.c: Fix ELSE and ELSE IF clauses. (add_clause): Drop TARGET_INDEX argument and figure out the target of the jump on our own. The caller couldn't compensate for the inserted BREAK transformation. Updated all callers. Fri Feb 2 22:41:43 WST 2007 John Darrington * repeat.c (parse_numbers): Fixed bug parseing ranges vs. lists. Ensured that floats are accepted in lists, but not in ranges. Tue Dec 19 08:12:46 2006 Ben Pfaff Fix LOOP. Thanks to Daniel Williams for reporting one of the bugs fixed here. * loop.c (cmd_loop): Keep track of whether we created the index variable and delete it if parsing fails, instead of creating it after parsing the IF clause. This allows the index variable to be used in the IF clause. This incidentally fixes a segfault when no index variable was used. Also, return CMD_CASCADING_FAILURE if we fail. (parse_if_clause): Don't allow more than one IF clause. (parse_index_clause): Don't allow more than one index clause. Create the index variable if it doesn't exist. (end_loop_trns_proc): Invert the sense of END LOOP's IF clause. Sat Dec 9 20:12:34 2006 Ben Pfaff * repeat.c (parse_lines): Issue an error when attempting to nest DO REPEAT in compatibility mode. Sat Dec 2 17:01:59 2006 Ben Pfaff Significant cleanup to DO REPEAT. * repeat.c: (struct line_list) Rename struct repeat_line. Use struct ll instead of explicit "next" pointer. Make "file_name" const. Change "const char *line" to "struct substring text". Add `syntax' member. Update all references. (enum repeat_entry_type) Rename repeat_macro_type, update all references. (struct repeat_entry) Rename struct repeat_macro. Use struct ll instead of explicit "next" pointer. Change "char[] id" to "struct substring name". Change "char **replacement" to "struct substring *replacements". Update all references. (struct repeat_block) Use struct ll_list for lists of lines, macros. Change "cur_line" to struct ll *. (cmd_do_repeat) Don't bother adding an empty getl source at all. This saves special-casing an empty source in repeat_read. (parse_specification) Use new find_macro function. (find_macro) New function. (skip_indentor) Removed. (recognize_keyword) Change interface, update callers. (recognize_do_repeat) Ditto. (recognize_end_repeat) Ditto. (parse_lines) Use lex_preprocess_line to preprocess the input line to check for DO REPEAT and END REPEAT, instead of coding it inline. (parse_ids) Need to make a copy of the array parsed by parse_mixed_vars_pool, instead of using it verbatim, because we're using struct substring now. (add_replacement) Use struct substring in interface, instead of const char *, and update all callers. (find_substitution) Rewrite using substring, in terms of find_macro. (do_repeat_filter) Use struct substring to simplify code. (current_line) New function. Sat Dec 2 16:40:12 2006 Ben Pfaff Fix lack of ->name and ->location in DO REPEAT's getl_interface. See bug #15702. * repeat.c: (cmd_do_repeat) Initialize name, location in getl_interface. (do_repeat_read) Adjust semantics of cur_line so that, after the call, it points to the line just returned, instead of to the next line to be returned. Thus, do_repeat_name and do_repeat_location can use cur_line to obtain the info they need. (do_repeat_name) New function. (do_repeat_location) New function. Thu Nov 30 22:01:27 2006 Ben Pfaff * repeat.c (do_repeat_read): Properly handle empty DO REPEAT...END REPEAT block. Fixes bug #18407. Thanks to John Darrington for reporting this bug. Sat Oct 28 16:18:48 WST 2006 John Darrington * repeat.c: Eliminated references to extern variable getl_buf. Sun May 7 18:18:33 2006 Ben Pfaff Fix memory leaks. * repeat.c: (parse_ids) Take pool parameter and allocate all memory from pool. Reduce implementation from loop to single call to parse_mixed_vars_pool(). (store_numeric) Removed. (add_replacement) New function. (parse_numbers) Take pool parameter and allocate all memory from pool. Require ranges to be in increasing order. (parse_strings) Take pool parameter and allocate all memory from pool. Wed May 3 22:45:41 2006 Ben Pfaff Continue reforming procedure execution. In this phase, get rid of many global variables, consolidating procedure execution in procedure.c. Encapsulate transformations in new "struct trns_chain". Also, change implementation of N OF CASES, FILTER, and PROCESS IF from special cases to transformations. * do-if.c: (cmd_do_if) Use finalizer to ensure control stack gets cleared. (do_if_finalize_func) New function. * loop.c: (create_loop_trns) Use finalizer to ensure control stack gets cleared. (loop_trns_finalize) New function. * temporary.c: (global var temporary) Removed. Changed references to use proc_make_temporary_transformations_permanent() or proc_in_temporary_transformations(). (global var temp_dict) Removed. (global var temp_trns) Removed. (cmd_temporary) Reimplement in terms of proc_in_temporary_transformations() and proc_start_temporary_transformations(). (cancel_temporary) Moved to procedure.c, renamed proc_cancel_temporary_transformations(). Thu Mar 2 08:40:33 WST 2006 John Darrington * Moved files from src directory
