   2
   3         Further clean up the CMD_* command result codes.
   4
   5         * command.c (cmd_result_is_valid): New function.
   6         (cmd_result_is_success) Assert that argument is valid.  Simplified
   7         check to one for a positive result.
   8         (cmd_result_is_failure) Assert that argument is valid.  Simplified
   9         check to one for a negative result.
  10         (do_parse_command) Check that command's returned result is valid.
  11
  12         * command.h: (enum cmd_result) Renamed CMD_QUIT to CMD_FINISH and
  13         updated all users.  Removed CMD_END_SUBLOOP in favor of new
  14         CMD_PRIVATE_FIRST...CMD_PRIVATE_LAST range.  Changed failure codes
  15         to have negative values.
  16
  17 Mon May  1 15:56:56 2006  Ben Pfaff  <blp@gnu.org>
  18
  19         Remove vestiges of FILE TYPE support.
  20
  21         * command.def: Mark FILE TYPE, RECORD TYPE unimplemented.
  22
  23 Wed Apr 26 21:13:46 2006  Ben Pfaff  <blp@gnu.org>
  24
  25         CLEAR TRANSFORMATIONS is unsafe as implemented.  It's a fair
  26         amount of work to implement it correctly, so make it
  27         unimplemented.
  28
  29         * command.c: (cmd_clear_transformations) Removed.
  30
  31         * command.def: Mark CLEAR TRANSFORMATIONS as unimplemented.
  32
  33 Wed Apr 26 13:06:42 2006  Ben Pfaff  <blp@gnu.org>
  34
  35         Work on readline completion.
  36
  37         * command.c: (pspp_completion_function) Removed.
  38         (pspp_attempted_completion_function) New function.
  39         (command_generator) New function.
  40
  41 Wed Apr 26 13:04:48 2006  Ben Pfaff  <blp@gnu.org>
  42
  43         Improve the way we handle the various parsing "states".  Until now
  44         we've hard-coded the state transitions in the command definition
  45         file, but that's error-prone and, worse, it's redundant--we can
  46         figure out what state we're in anyhow.  We can cleanly handle
  47         INPUT PROGRAM and FILE TYPE with a nested command-processing loop.
  48
  49         * command.c: (cmd_result_is_success) New function.
  50         (cmd_result_is_failure) New function.
  51         (enum states) New enum.
  52         (enum flags) New enum.
  53         (struct command) Add states, flags members.  Remove transition,
  54         skip_entire_name, debug members.  Renamed func member as function.
  55         (macro DEFCMD) Removed.
  56         (macro DBGCMD) Removed.
  57         (macro SPCCMD) Removed.
  58         (macro UNIMPL) Removed.
  59         (macro DEF_CMD) New.
  60         (macro UNIMPL_CMD) New.
  61         (macro COMMAND_CNT) Changed to static const var, renamed
  62         command_cnt.  Updated all references.
  63         (FILE_TYPE_okay) Removed.
  64         (cmd_parse) Rewrote in terms of do_parse_command().
  65         (do_parse_command) New function.
  66         (find_command) New function.
  67         (unknown_command_error) Use struct string to simplify code.
  68         (parse_command_name) Recognize comment command names.  Handle
  69         flags.  Don't reject testing-mode-only commands here--let higher
  70         level do it.
  71         (verify_valid_command) New function.
  72         (cmd_comment) New function.
  73
  74         * command.def: Completely rewritten and now sensibly organized.

  80         Added CMD_NOT_IMPLEMENTED.
  81         (macro DEFCMD) Removed.
  82         (macro DBGCMD) Removed.
  83         (macro SPCCMD) Removed.
  84         (macro UNIMPL) Removed.
  85         (macro DEF_CMD) New.
  86         (macro UNIMPL_CMD) New.
  87
  88 Mon Apr  3 11:03:36 2006  Ben Pfaff  <blp@gnu.org>
  89
  90         * list.q: (write_all_headers) Adapt to new html and output
  91         internals.
