- This file documents the changes from version 2.1 of S.el (also known
- as gnuemacs3 on Statlib) and the current version.
-
- 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.
