27 | ;;; This file defines a a lisp-in-a-buffer package (inferior-lisp |
28 | ;;; mode) built on top of comint mode. This version is more | |
29 | ;;; featureful, robust, and uniform than the Emacs 18 version. The | |
30 | ;;; key bindings are also more compatible with the bindings of Hemlock | |
31 | ;;; and Zwei (the Lisp Machine emacs). | |
2f790b20 JB |
32 | |
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. | |
37 | ||
38 | ;;; For documentation on the functionality provided by comint mode, and | |
39 | ;;; the hooks available for customising it, see the file comint.el. | |
926d5019 | 40 | ;;; For further information on inferior-lisp mode, see the comments below. |

42 | ;;; Needs fixin: | |
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, ...). | |
50 | ;;; | |
926d5019 | 51 | ;;; It would be nice if inferior-lisp (and inferior scheme, T, ...) modes |
2f790b20 JB |
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? | |
55 | ;;; | |
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? | |

167 | MULTIPLE PROCESS SUPPORT | |
168 | =========================================================================== | |
169 | To run multiple Lisp processes, you start the first up | |
170 | with \\[inferior-lisp]. It will be in a buffer named `*inferior-lisp*'. | |
171 | Rename this buffer with \\[rename-buffer]. You may now start up a new | |
172 | process with another \\[inferior-lisp]. It will be in a new buffer, | |
173 | named `*inferior-lisp*'. You can switch between the different process | |
174 | buffers with \\[switch-to-buffer]. | |
175 | ||
176 | Commands that send text from source buffers to Lisp processes -- | |
177 | like `lisp-eval-defun' or `lisp-show-arglist' -- have to choose a process | |
178 | to send to, when you have more than one Lisp process around. This | |
179 | is determined by the global variable `inferior-lisp-buffer'. Suppose you | |
180 | have three inferior Lisps running: | |
181 | Buffer Process | |
182 | foo inferior-lisp | |
183 | bar inferior-lisp<2> | |
184 | *inferior-lisp* inferior-lisp<3> | |
185 | If you do a \\[lisp-eval-defun] command on some Lisp source code, | |
186 | what process do you send it to? | |
187 | ||
188 | - If you're in a process buffer (foo, bar, or *inferior-lisp*), | |
189 | you send it to that process. | |
190 | - If you're in some other buffer (e.g., a source file), you | |
191 | send it to the process attached to buffer `inferior-lisp-buffer'. | |
192 | This process selection is performed by function `inferior-lisp-proc'. | |
193 | ||
194 | Whenever \\[inferior-lisp] fires up a new process, it resets | |
195 | `inferior-lisp-buffer' to be the new process's buffer. If you only run | |
196 | one process, this does the right thing. If you run multiple | |
197 | processes, you can change `inferior-lisp-buffer' to another process | |
198 | buffer with \\[set-variable].") | |

590 | ;;; 7/21/92 Jim Blandy |
591 | ;;; - Changed all uses of the cmulisp name or prefix to inferior-lisp; | |
592 | ;;; this is now the official inferior lisp package. Use the global | |
593 | ;;; ChangeLog from now on. | |
2f790b20 JB |
594 | ;;; 5/24/90 Olin |
595 | ;;; - Split cmulisp and cmushell modes into separate files. | |
596 | ;;; Not only is this a good idea, it's apparently the way it'll be rel 19. | |
597 | ;;; - Upgraded process sends to use comint-send-string instead of | |
598 | ;;; process-send-string. | |
599 | ;;; - Explicit references to process "cmulisp" have been replaced with | |
600 | ;;; (cmulisp-proc). This allows better handling of multiple process bufs. | |
601 | ;;; - Added process query and var/function/symbol documentation | |
602 | ;;; commands. Based on code written by Douglas Roberts. | |
603 | ;;; - Added lisp-eval-last-sexp, bound to C-x C-e. | |
604 | ;;; | |
605 | ;;; 9/20/90 Olin | |
606 | ;;; Added a save-restriction to lisp-fn-called-at-pt. This bug and fix | |
607 | ;;; reported by Lennart Staflin. | |
608 | ;;; | |
609 | ;;; 3/12/90 Olin | |
610 | ;;; - lisp-load-file and lisp-compile-file no longer switch-to-lisp. | |
611 | ;;; Tale suggested this. | |
daa37602 JB |
612 | ;;; - Reversed this decision 7/15/91. You need the visual feedback. |
613 | ;;; | |
614 | ;;; 7/25/91 Olin | |
615 | ;;; Changed all keybindings of the form C-c <letter>. These are | |
616 | ;;; supposed to be reserved for the user to bind. This affected | |
617 | ;;; mainly the compile/eval-defun/region[-and-go] commands. | |
618 | ;;; This was painful, but necessary to adhere to the gnumacs standard. | |
619 | ;;; For some backwards compatibility, see the | |
620 | ;;; cmulisp-install-letter-bindings | |
621 | ;;; function. | |
622 | ;;; | |
623 | ;;; 8/2/91 Olin | |
624 | ;;; - The lisp-compile/eval-defun/region commands now take a prefix arg, | |
625 | ;;; which means switch-to-lisp after sending the text to the Lisp process. | |
626 | ;;; This obsoletes all the -and-go commands. The -and-go commands are | |
627 | ;;; kept around for historical reasons, and because the user can bind | |
628 | ;;; them to key sequences shorter than C-u C-c C-<letter>. | |
629 | ;;; - If M-x cmulisp is invoked with a prefix arg, it allows you to | |
630 | ;;; edit the command line. | |
