27 ;; This file defines a lisp-in-a-buffer package (inferior-lisp mode)
28 ;; built on top of comint mode. This version is more featureful,
29 ;; robust, and uniform than the Emacs 18 version. The key bindings are
30 ;; also more compatible with the bindings of Hemlock and Zwei (the
31 ;; Lisp Machine emacs).
33 ;; Since this mode is built on top of the general command-interpreter-in-
34 ;; a-buffer mode (comint mode), it shares a common base functionality,
35 ;; and a common set of bindings, with all modes derived from comint mode.
36 ;; This makes these modes easier to use.
38 ;; For documentation on the functionality provided by comint mode, and
39 ;; the hooks available for customizing it, see the file comint.el.
40 ;; For further information on inferior-lisp mode, see the comments below.
43 ;; The load-file/compile-file default mechanism could be smarter -- it
44 ;; doesn't know about the relationship between filename extensions and
45 ;; whether the file is source or executable. If you compile foo.lisp
46 ;; with compile-file, then the next load-file should use foo.bin for
47 ;; the default, not foo.lisp. This is tricky to do right, particularly
48 ;; because the extension for executable files varies so much (.o, .bin,
49 ;; .lbin, .mo, .vo, .ao, ...).
51 ;; It would be nice if inferior-lisp (and inferior scheme, T, ...) modes
52 ;; had a verbose minor mode wherein sending or compiling defuns, etc.
53 ;; would be reflected in the transcript with suitable comments, e.g.
54 ;; ";;; redefining fact". Several ways to do this. Which is right?
56 ;; When sending text from a source file to a subprocess, the process-mark can
57 ;; move off the window, so you can lose sight of the process interactions.
58 ;; Maybe I should ensure the process mark is in the window when I send
59 ;; text to the process? Switch selectable?

173 MULTIPLE PROCESS SUPPORT
174 ===========================================================================
175 To run multiple Lisp processes, you start the first up
176 with \\[inferior-lisp]. It will be in a buffer named `*inferior-lisp*'.
177 Rename this buffer with \\[rename-buffer]. You may now start up a new
178 process with another \\[inferior-lisp]. It will be in a new buffer,
179 named `*inferior-lisp*'. You can switch between the different process
180 buffers with \\[switch-to-buffer].
182 Commands that send text from source buffers to Lisp processes --
183 like `lisp-eval-defun' or `lisp-show-arglist' -- have to choose a process
184 to send to, when you have more than one Lisp process around. This
185 is determined by the global variable `inferior-lisp-buffer'. Suppose you
186 have three inferior Lisps running:
190 *inferior-lisp* inferior-lisp<3>
191 If you do a \\[lisp-eval-defun] command on some Lisp source code,
192 what process do you send it to?
194 - If you're in a process buffer (foo, bar, or *inferior-lisp*),
195 you send it to that process.
196 - If you're in some other buffer (e.g., a source file), you
197 send it to the process attached to buffer `inferior-lisp-buffer'.
198 This process selection is performed by function `inferior-lisp-proc'.
200 Whenever \\[inferior-lisp] fires up a new process, it resets
201 `inferior-lisp-buffer' to be the new process's buffer. If you only run
202 one process, this does the right thing. If you run multiple
203 processes, you can change `inferior-lisp-buffer' to another process
204 buffer with \\[set-variable].")

213 Runs a Lisp interpreter as a subprocess of Emacs, with Lisp I/O through an

225 `inferior-lisp-mode-hook' (in that order).
227 You can send text to the inferior Lisp process from other buffers containing
229 `switch-to-lisp' switches the current buffer to the Lisp process buffer.
230 `lisp-eval-defun' sends the current defun to the Lisp process.
231 `lisp-compile-defun' compiles the current defun.
232 `lisp-eval-region' sends the current region to the Lisp process.
233 `lisp-compile-region' compiles the current region.
235 Prefixing the lisp-eval/compile-defun/region commands with
236 a \\[universal-argument] causes a switch to the Lisp process buffer after sending
239 Commands:\\<inferior-lisp-mode-map>
240 \\[comint-send-input] after the end of the process' output sends the text from the
241 end of process to point.
242 \\[comint-send-input] before the end of the process' output copies the sexp ending at point
243 to the end of the process' output, and sends it.
244 \\[comint-copy-old-input] copies the sexp ending at point to the end of the process' output,
245 allowing you to edit it before sending it.
246 If `comint-use-prompt-regexp' is nil (the default), \\[comint-insert-input] on old input
247 copies the entire old input to the end of the process' output, allowing
248 you to edit it before sending it. When not used on old input, or if
249 `comint-use-prompt-regexp' is non-nil, \\[comint-insert-input] behaves according to

603 ;;; 7/21/92 Jim Blandy
604 ;;; - Changed all uses of the cmulisp name or prefix to inferior-lisp;
605 ;;; this is now the official inferior lisp package. Use the global
606 ;;; ChangeLog from now on.
608 ;;; - Split cmulisp and cmushell modes into separate files.
609 ;;; Not only is this a good idea, it's apparently the way it'll be rel 19.
610 ;;; - Upgraded process sends to use comint-send-string instead of
611 ;;; process-send-string.
612 ;;; - Explicit references to process "cmulisp" have been replaced with
613 ;;; (cmulisp-proc). This allows better handling of multiple process bufs.
614 ;;; - Added process query and var/function/symbol documentation
615 ;;; commands. Based on code written by Douglas Roberts.
616 ;;; - Added lisp-eval-last-sexp, bound to C-x C-e.
619 ;;; Added a save-restriction to lisp-fn-called-at-pt. This bug and fix
620 ;;; reported by Lennart Staflin.
623 ;;; - lisp-load-file and lisp-compile-file no longer switch-to-lisp.
624 ;;; Tale suggested this.
625 ;;; - Reversed this decision 7/15/91. You need the visual feedback.
628 ;;; Changed all keybindings of the form C-c <letter>. These are
629 ;;; supposed to be reserved for the user to bind. This affected
630 ;;; mainly the compile/eval-defun/region[-and-go] commands.
631 ;;; This was painful, but necessary to adhere to the gnumacs standard.
632 ;;; For some backwards compatibility, see the
633 ;;; cmulisp-install-letter-bindings
637 ;;; - The lisp-compile/eval-defun/region commands now take a prefix arg,
638 ;;; which means switch-to-lisp after sending the text to the Lisp process.
639 ;;; This obsoletes all the -and-go commands. The -and-go commands are
640 ;;; kept around for historical reasons, and because the user can bind
641 ;;; them to key sequences shorter than C-u C-c C-<letter>.
642 ;;; - If M-x cmulisp is invoked with a prefix arg, it allows you to
643 ;;; edit the command line.
647 ;;; inf-lisp.el ends here
