   1 Mon May  1 15:56:56 2006  Ben Pfaff  <blp@gnu.org>
   2
   3         Remove vestiges of FILE TYPE support.
   4
   5         * command.def: Mark FILE TYPE, RECORD TYPE unimplemented.
   6
   7 Wed Apr 26 21:13:46 2006  Ben Pfaff  <blp@gnu.org>
   8
   9         CLEAR TRANSFORMATIONS is unsafe as implemented.  It's a fair
  10         amount of work to implement it correctly, so make it
  11         unimplemented.
  12
  13         * command.c: (cmd_clear_transformations) Removed.
  14
  15         * command.def: Mark CLEAR TRANSFORMATIONS as unimplemented.
  16
  17 Wed Apr 26 13:06:42 2006  Ben Pfaff  <blp@gnu.org>
  18
  19         Work on readline completion.
  20
  21         * command.c: (pspp_completion_function) Removed.
  22         (pspp_attempted_completion_function) New function.
  23         (command_generator) New function.
  24
  25 Wed Apr 26 13:04:48 2006  Ben Pfaff  <blp@gnu.org>
  26
  27         Improve the way we handle the various parsing "states".  Until now
  28         we've hard-coded the state transitions in the command definition
  29         file, but that's error-prone and, worse, it's redundant--we can
  30         figure out what state we're in anyhow.  We can cleanly handle
  31         INPUT PROGRAM and FILE TYPE with a nested command-processing loop.
  32
  33         * command.c: (cmd_result_is_success) New function.
  34         (cmd_result_is_failure) New function.
  35         (enum states) New enum.
  36         (enum flags) New enum.
  37         (struct command) Add states, flags members.  Remove transition,
  38         skip_entire_name, debug members.  Renamed func member as function.
  39         (macro DEFCMD) Removed.
  40         (macro DBGCMD) Removed.
  41         (macro SPCCMD) Removed.
  42         (macro UNIMPL) Removed.
  43         (macro DEF_CMD) New.
  44         (macro UNIMPL_CMD) New.
  45         (macro COMMAND_CNT) Changed to static const var, renamed
  46         command_cnt.  Updated all references.
  47         (FILE_TYPE_okay) Removed.
  48         (cmd_parse) Rewrote in terms of do_parse_command().
  49         (do_parse_command) New function.
  50         (find_command) New function.
  51         (unknown_command_error) Use struct string to simplify code.
  52         (parse_command_name) Recognize comment command names.  Handle
  53         flags.  Don't reject testing-mode-only commands here--let higher
  54         level do it.
  55         (verify_valid_command) New function.
  56         (cmd_comment) New function.
  57
  58         * command.def: Completely rewritten and now sensibly organized.
  59
  60         * command.h: (enum STATE_*) Renamed CMD_STATE_*.
  61         (CMD_*) Now "enum cmd_result".  Added CMD_QUIT.  New
  62         CMD_END_SUBLOOP.  Removed CMD_TRAILING_GARBAGE, CMD_PART_SUCCESS,
  63         CMD_PART_SUCCESS_MAYBE and replaced all references by CMD_FAILURE.
  64         Added CMD_NOT_IMPLEMENTED.
  65         (macro DEFCMD) Removed.
  66         (macro DBGCMD) Removed.
  67         (macro SPCCMD) Removed.
  68         (macro UNIMPL) Removed.
  69         (macro DEF_CMD) New.
  70         (macro UNIMPL_CMD) New.
  71
  72 Mon Apr  3 11:03:36 2006  Ben Pfaff  <blp@gnu.org>
  73
  74         * list.q: (write_all_headers) Adapt to new html and output
  75         internals.
