26 | ;; Hacked from tea.el by Olin Shivers (shivers@cs.cmu.edu). 8/88 |
27 | ||
d864d774 | 28 | ;; This file defines a lisp-in-a-buffer package (inferior-lisp mode) |
443e60bf JB |
29 | ;; built on top of comint mode. This version is more featureful, |
30 | ;; robust, and uniform than the Emacs 18 version. The key bindings are | |
d864d774 JB |
31 | ;; also more compatible with the bindings of Hemlock and Zwei (the |
32 | ;; Lisp Machine emacs). | |
b578f267 EN |
33 | |
34 | ;; Since this mode is built on top of the general command-interpreter-in- | |
690ec649 | 35 | ;; a-buffer mode (comint mode), it shares a common base functionality, |
b578f267 EN |
36 | ;; and a common set of bindings, with all modes derived from comint mode. |
37 | ;; This makes these modes easier to use. | |
38 | ||
39 | ;; For documentation on the functionality provided by comint mode, and | |
40 | ;; the hooks available for customising it, see the file comint.el. | |
41 | ;; For further information on inferior-lisp mode, see the comments below. | |
42 | ||
43 | ;; Needs fixin: | |
44 | ;; The load-file/compile-file default mechanism could be smarter -- it | |
45 | ;; doesn't know about the relationship between filename extensions and | |
46 | ;; whether the file is source or executable. If you compile foo.lisp | |
47 | ;; with compile-file, then the next load-file should use foo.bin for | |
48 | ;; the default, not foo.lisp. This is tricky to do right, particularly | |
49 | ;; because the extension for executable files varies so much (.o, .bin, | |
50 | ;; .lbin, .mo, .vo, .ao, ...). | |
51 | ;; | |
52 | ;; It would be nice if inferior-lisp (and inferior scheme, T, ...) modes | |
53 | ;; had a verbose minor mode wherein sending or compiling defuns, etc. | |
54 | ;; would be reflected in the transcript with suitable comments, e.g. | |
55 | ;; ";;; redefining fact". Several ways to do this. Which is right? | |
56 | ;; | |
690ec649 | 57 | ;; When sending text from a source file to a subprocess, the process-mark can |
b578f267 EN |
58 | ;; move off the window, so you can lose sight of the process interactions. |
59 | ;; Maybe I should ensure the process mark is in the window when I send | |
60 | ;; text to the process? Switch selectable? | |

180 | MULTIPLE PROCESS SUPPORT | |
181 | =========================================================================== | |
182 | To run multiple Lisp processes, you start the first up | |
183 | with \\[inferior-lisp]. It will be in a buffer named `*inferior-lisp*'. | |
184 | Rename this buffer with \\[rename-buffer]. You may now start up a new | |
185 | process with another \\[inferior-lisp]. It will be in a new buffer, | |
186 | named `*inferior-lisp*'. You can switch between the different process | |
187 | buffers with \\[switch-to-buffer]. | |
188 | ||
189 | Commands that send text from source buffers to Lisp processes -- | |
190 | like `lisp-eval-defun' or `lisp-show-arglist' -- have to choose a process | |
191 | to send to, when you have more than one Lisp process around. This | |
192 | is determined by the global variable `inferior-lisp-buffer'. Suppose you | |
193 | have three inferior Lisps running: | |
194 | Buffer Process | |
195 | foo inferior-lisp | |
196 | bar inferior-lisp<2> | |
197 | *inferior-lisp* inferior-lisp<3> | |
690ec649 | 198 | If you do a \\[lisp-eval-defun] command on some Lisp source code, |
cbd1f89c RS |
199 | what process do you send it to? |
200 | ||
690ec649 | 201 | - If you're in a process buffer (foo, bar, or *inferior-lisp*), |
cbd1f89c RS |
202 | you send it to that process. |
203 | - If you're in some other buffer (e.g., a source file), you | |
204 | send it to the process attached to buffer `inferior-lisp-buffer'. | |
205 | This process selection is performed by function `inferior-lisp-proc'. | |
206 | ||
207 | Whenever \\[inferior-lisp] fires up a new process, it resets | |
208 | `inferior-lisp-buffer' to be the new process's buffer. If you only run | |
209 | one process, this does the right thing. If you run multiple | |
210 | processes, you can change `inferior-lisp-buffer' to another process | |
211 | buffer with \\[set-variable].") | |

926d5019 JB |
612 | ;;; 7/21/92 Jim Blandy |
613 | ;;; - Changed all uses of the cmulisp name or prefix to inferior-lisp; | |
614 | ;;; this is now the official inferior lisp package. Use the global | |
615 | ;;; ChangeLog from now on. | |
2f790b20 | 616 | ;;; 5/24/90 Olin |
690ec649 | 617 | ;;; - Split cmulisp and cmushell modes into separate files. |
2f790b20 JB |
618 | ;;; Not only is this a good idea, it's apparently the way it'll be rel 19. |
619 | ;;; - Upgraded process sends to use comint-send-string instead of | |
620 | ;;; process-send-string. | |
621 | ;;; - Explicit references to process "cmulisp" have been replaced with | |
622 | ;;; (cmulisp-proc). This allows better handling of multiple process bufs. | |
623 | ;;; - Added process query and var/function/symbol documentation | |
624 | ;;; commands. Based on code written by Douglas Roberts. | |
625 | ;;; - Added lisp-eval-last-sexp, bound to C-x C-e. | |
626 | ;;; | |
627 | ;;; 9/20/90 Olin | |
628 | ;;; Added a save-restriction to lisp-fn-called-at-pt. This bug and fix | |
629 | ;;; reported by Lennart Staflin. | |
630 | ;;; | |
631 | ;;; 3/12/90 Olin | |
632 | ;;; - lisp-load-file and lisp-compile-file no longer switch-to-lisp. | |
633 | ;;; Tale suggested this. | |
daa37602 JB |
634 | ;;; - Reversed this decision 7/15/91. You need the visual feedback. |
635 | ;;; | |
636 | ;;; 7/25/91 Olin | |
637 | ;;; Changed all keybindings of the form C-c <letter>. These are | |
638 | ;;; supposed to be reserved for the user to bind. This affected | |
639 | ;;; mainly the compile/eval-defun/region[-and-go] commands. | |
640 | ;;; This was painful, but necessary to adhere to the gnumacs standard. | |
690ec649 | 641 | ;;; For some backwards compatibility, see the |
daa37602 JB |
642 | ;;; cmulisp-install-letter-bindings |
643 | ;;; function. | |
644 | ;;; | |
645 | ;;; 8/2/91 Olin | |
646 | ;;; - The lisp-compile/eval-defun/region commands now take a prefix arg, | |
647 | ;;; which means switch-to-lisp after sending the text to the Lisp process. | |
648 | ;;; This obsoletes all the -and-go commands. The -and-go commands are | |
649 | ;;; kept around for historical reasons, and because the user can bind | |
650 | ;;; them to key sequences shorter than C-u C-c C-<letter>. | |
651 | ;;; - If M-x cmulisp is invoked with a prefix arg, it allows you to | |
652 | ;;; edit the command line. | |
