+
+ Continue reforming procedure execution. In this phase, remove
+ PROCESS IF, which was deprecated anyway and can be easily
+ simulated with TEMPORARY followed by SELECT IF.
+
+ * command.def: Removed PROCESS IF.
+
+Mon May 1 18:17:52 2006 Ben Pfaff <blp@gnu.org>
+
+ Further clean up the CMD_* command result codes.
+
+ * command.c (cmd_result_is_valid): New function.
+ (cmd_result_is_success) Assert that argument is valid. Simplified
+ check to one for a positive result.
+ (cmd_result_is_failure) Assert that argument is valid. Simplified
+ check to one for a negative result.
+ (do_parse_command) Check that command's returned result is valid.
+
+ * command.h: (enum cmd_result) Renamed CMD_QUIT to CMD_FINISH and
+ updated all users. Removed CMD_END_SUBLOOP in favor of new
+ CMD_PRIVATE_FIRST...CMD_PRIVATE_LAST range. Changed failure codes
+ to have negative values.
+
+Mon May 1 15:56:56 2006 Ben Pfaff <blp@gnu.org>
+
+ Remove vestiges of FILE TYPE support.
+
+ * command.def: Mark FILE TYPE, RECORD TYPE unimplemented.
+

+
+ CLEAR TRANSFORMATIONS is unsafe as implemented. It's a fair
+ amount of work to implement it correctly, so make it
+ unimplemented.
+
+ * command.c: (cmd_clear_transformations) Removed.
+
+ * command.def: Mark CLEAR TRANSFORMATIONS as unimplemented.
+
+Wed Apr 26 13:06:42 2006 Ben Pfaff <blp@gnu.org>
+
+ Work on readline completion.
+
+ * command.c: (pspp_completion_function) Removed.
+ (pspp_attempted_completion_function) New function.
+ (command_generator) New function.
+
+Wed Apr 26 13:04:48 2006 Ben Pfaff <blp@gnu.org>
+
+ Improve the way we handle the various parsing "states". Until now
+ we've hard-coded the state transitions in the command definition
+ file, but that's error-prone and, worse, it's redundant--we can
+ figure out what state we're in anyhow. We can cleanly handle
+ INPUT PROGRAM and FILE TYPE with a nested command-processing loop.
+
+ * command.c: (cmd_result_is_success) New function.
+ (cmd_result_is_failure) New function.
+ (enum states) New enum.
+ (enum flags) New enum.
+ (struct command) Add states, flags members. Remove transition,
+ skip_entire_name, debug members. Renamed func member as function.
+ (macro DEFCMD) Removed.
+ (macro DBGCMD) Removed.
+ (macro SPCCMD) Removed.
+ (macro UNIMPL) Removed.
+ (macro DEF_CMD) New.
+ (macro UNIMPL_CMD) New.
+ (macro COMMAND_CNT) Changed to static const var, renamed
+ command_cnt. Updated all references.
+ (FILE_TYPE_okay) Removed.
+ (cmd_parse) Rewrote in terms of do_parse_command().
+ (do_parse_command) New function.
+ (find_command) New function.
+ (unknown_command_error) Use struct string to simplify code.
+ (parse_command_name) Recognize comment command names. Handle
+ flags. Don't reject testing-mode-only commands here--let higher
+ level do it.
+ (verify_valid_command) New function.
+ (cmd_comment) New function.
+
+ * command.def: Completely rewritten and now sensibly organized.
+
+ * command.h: (enum STATE_*) Renamed CMD_STATE_*.
+ (CMD_*) Now "enum cmd_result". Added CMD_QUIT. New
+ CMD_END_SUBLOOP. Removed CMD_TRAILING_GARBAGE, CMD_PART_SUCCESS,
+ CMD_PART_SUCCESS_MAYBE and replaced all references by CMD_FAILURE.
+ Added CMD_NOT_IMPLEMENTED.
+ (macro DEFCMD) Removed.
+ (macro DBGCMD) Removed.
+ (macro SPCCMD) Removed.
+ (macro UNIMPL) Removed.
+ (macro DEF_CMD) New.
+ (macro UNIMPL_CMD) New.
