CHANGES

For current users of S-mode, here are some of the incompatible
changes and features new to version 3.3 of S-mode:

• Command-line completion of object names, and faster completion in
  other situations.

• Hot Keys for the commonly-used functions objects(),
  search() and attach() and a facility to add your own hot keys
  with keyboard macros.

• Simultaneous multiple function editing, with integrated
  error-checking and parsing. Mnemonic names for edit buffers.

• Debugging features: facility for stepping through S code and
  evaluating portions of code with the output appearing as if the
  commands has been typed in manually.

• S can now be run from a different directory each session.

• A dedicated mode for viewing S help files. Individual help
  buffers are maintained for quick repeated access. Completion for
  help files without a corresponding object.

• Facility for maintaining organised backups of S source code.

• Indenting and formatting commands for editing S source code.

• Special handling of the S graphics facilities, including an
  experimental Tek graphics mode.

• Better handling of temporary files and buffers.

• Some keybindings have changed to conform to GNU guidelines.

Here are the changes to the keybindings from version 2.1:

INFERIOR-S-MODE:

C-c h    S-display-help-on-object    MOVED TO	   C-c C-h         [*]
C-c d    S-dump-object-into-scratch  MOVED TO	   C-c C-d	   [*]
C-c l    S-load-file		     MOVED TO	   C-c C-l	   [*]
C-c C-o  comint-kill-output          REDEFINED AS  S-kill-output
C-c C-z	 comint-stop-subjob	     REDEFINED AS  S-abort

S-MODE:

C-c h    S-display-help-on-object    MOVED TO	   C-c C-h	   [*]
C-c l    S-load-file		     MOVED TO	   C-c C-l	   [*]
C-c z    switch-to-S		     MOVED TO	   C-c C-y	   [*]
C-c C-k  S-eval-line-and-go          MOVED TO	   C-c M-j	   [*]
C-c k	 S-eval-line		     MOVED TO	   C-c C-j	   [*]
C-c C-e  S-eval-function-and-go      MOVED TO	   C-c M-f
				     REDEFINED AS  S-execute-in-tb
C-c e    S-eval-function	     MOVED TO	   C-c C-f	   [*]
C-c C-b	 S-eval-buffer-and-go	     MOVED TO	   C-c M-b
C-c b	 S-eval-buffer		     MOVED TO	   C-c C-b	   [*]
C-c C-r	 S-eval-region-and-go	     MOVED TO	   C-c M-r
C-c r	 S-eval-region		     MOVED TO	   C-c C-r	   [*]

If your fingers insist on using the old bindings, place the following
piece of code in your .emacs to emulate the bindings marked [*] above:

(setq S-mode-load-hook
      '(lambda nil
	 (define-key inferior-S-mode-map "\C-ch" 'S-display-help-on-object)
	 (define-key inferior-S-mode-map "\C-cl" 'S-load-file)
	 (define-key inferior-S-mode-map "\C-cd" 'S-dump-object-into-edit-buffer)
	 (define-key S-mode-map "\C-ch" 'S-display-help-on-object)
	 (define-key S-mode-map "\C-cl" 'S-load-file)
	 (define-key S-mode-map "\C-cz" 'S-switch-to-S)
	 (define-key S-mode-map "\C-c\C-k" 'S-eval-line-and-go)
	 (define-key S-mode-map "\C-ck" 'S-eval-line)
	 (define-key S-mode-map "\C-ce" 'S-eval-function)
	 (define-key S-mode-map "\C-cb" 'S-eval-buffer)
	 (define-key S-mode-map "\C-cr" 'S-eval-region)))

However, I do encourage you to become familiar with the new bindings.

• General code cleanups and optimizations.

In particular, a number of variable and function names have been
changed. You may need to modify any hooks you used in version 2.1. The
changes are:

(some of these symbols were not present in version 2.1 of S.el, but
have been used in private releases since 2.1)

In addition, many of the internal functions have been modified in
implementation and/or usage. See S.el for more information.

S-mode 2.1

Improvements since last release (unnumbered of Summer 1990):

• Better description provided of functions loaded.

• Better header for this file.

• S-directory is now a prescriptive rather than just
  descriptive variable.

• better syntax table, so |#; are better recognized and
  commands using them work better.

• we have a version number.
