   2
   3         CLEAR TRANSFORMATIONS is unsafe as implemented.  It's a fair
   4         amount of work to implement it correctly, so make it
   5         unimplemented.
   6
   7         * command.c: (cmd_clear_transformations) Removed.
   8
   9         * command.def: Mark CLEAR TRANSFORMATIONS as unimplemented.
  10
  11 Wed Apr 26 13:06:42 2006  Ben Pfaff  <blp@gnu.org>
  12
  13         Work on readline completion.
  14
  15         * command.c: (pspp_completion_function) Removed.
  16         (pspp_attempted_completion_function) New function.
  17         (command_generator) New function.
  18
  19 Wed Apr 26 13:04:48 2006  Ben Pfaff  <blp@gnu.org>
  20
  21         Improve the way we handle the various parsing "states".  Until now
  22         we've hard-coded the state transitions in the command definition
  23         file, but that's error-prone and, worse, it's redundant--we can
  24         figure out what state we're in anyhow.  We can cleanly handle
  25         INPUT PROGRAM and FILE TYPE with a nested command-processing loop.
  26
  27         * command.c: (cmd_result_is_success) New function.
  28         (cmd_result_is_failure) New function.
  29         (enum states) New enum.
  30         (enum flags) New enum.
  31         (struct command) Add states, flags members.  Remove transition,
  32         skip_entire_name, debug members.  Renamed func member as function.
  33         (macro DEFCMD) Removed.
  34         (macro DBGCMD) Removed.
  35         (macro SPCCMD) Removed.
  36         (macro UNIMPL) Removed.
  37         (macro DEF_CMD) New.
  38         (macro UNIMPL_CMD) New.
  39         (macro COMMAND_CNT) Changed to static const var, renamed
  40         command_cnt.  Updated all references.
  41         (FILE_TYPE_okay) Removed.
  42         (cmd_parse) Rewrote in terms of do_parse_command().
  43         (do_parse_command) New function.
  44         (find_command) New function.
  45         (unknown_command_error) Use struct string to simplify code.
  46         (parse_command_name) Recognize comment command names.  Handle
  47         flags.  Don't reject testing-mode-only commands here--let higher
  48         level do it.
  49         (verify_valid_command) New function.
  50         (cmd_comment) New function.
  51
  52         * command.def: Completely rewritten and now sensibly organized.
  53
  54         * command.h: (enum STATE_*) Renamed CMD_STATE_*.
  55         (CMD_*) Now "enum cmd_result".  Added CMD_QUIT.  New
  56         CMD_END_SUBLOOP.  Removed CMD_TRAILING_GARBAGE, CMD_PART_SUCCESS,
  57         CMD_PART_SUCCESS_MAYBE and replaced all references by CMD_FAILURE.
  58         Added CMD_NOT_IMPLEMENTED.
  59         (macro DEFCMD) Removed.
  60         (macro DBGCMD) Removed.
  61         (macro SPCCMD) Removed.
  62         (macro UNIMPL) Removed.
  63         (macro DEF_CMD) New.
  64         (macro UNIMPL_CMD) New.
  65
  66 Mon Apr  3 11:03:36 2006  Ben Pfaff  <blp@gnu.org>
  67
  68         * list.q: (write_all_headers) Adapt to new html and output
  69         internals.
