25 | ;;; This is a customisation of comint-mode (see comint.el) |
26 | ;;; | |
27 | ;;; Written by Olin Shivers (olin.shivers@cs.cmu.edu). With bits and pieces | |
28 | ;;; lifted from scheme.el, shell.el, clisp.el, newclisp.el, cobol.el, et al.. | |
29 | ;;; 8/88 | |
30 | ;;; | |
31 | ;;; Please send me bug reports, bug fixes, and extensions, so that I can | |
32 | ;;; merge them into the master source. | |
33 | ;;; | |
34 | ;;; The changelog is at the end of this file. | |
35 | ;;; | |
36 | ;;; NOTE: MIT Cscheme, when invoked with the -emacs flag, has a special user | |
37 | ;;; interface that communicates process state back to the superior emacs by | |
38 | ;;; outputting special control sequences. The gnumacs package, xscheme.el, has | |
39 | ;;; lots and lots of special purpose code to read these control sequences, and | |
40 | ;;; so is very tightly integrated with the cscheme process. The cscheme | |
41 | ;;; interrupt handler and debugger read single character commands in cbreak | |
42 | ;;; mode; when this happens, xscheme.el switches to special keymaps that bind | |
43 | ;;; the single letter command keys to emacs functions that directly send the | |
44 | ;;; character to the scheme process. Cmuscheme mode does *not* provide this | |
45 | ;;; functionality. If you are a cscheme user, you may prefer to use the | |
46 | ;;; xscheme.el/cscheme -emacs interaction. | |
47 | ;;; | |
48 | ;;; Here's a summary of the pros and cons, as I see them. | |
49 | ;;; xscheme: Tightly integrated with inferior cscheme process! A few commands | |
50 | ;;; not in cmuscheme. But. Integration is a bit of a hack. Input | |
51 | ;;; history only keeps the immediately prior input. Bizarre | |
52 | ;;; keybindings. | |
53 | ;;; | |
54 | ;;; cmuscheme: Not tightly integrated with inferior cscheme process. But. | |
55 | ;;; Carefully integrated functionality with the entire suite of | |
56 | ;;; comint-derived CMU process modes. Keybindings reminiscent of | |
57 | ;;; Zwei and Hemlock. Good input history. A few commands not in | |
58 | ;;; xscheme. | |
59 | ;;; | |
60 | ;;; It's a tradeoff. Pay your money; take your choice. If you use a Scheme | |
61 | ;;; that isn't Cscheme, of course, there isn't a choice. Xscheme.el is *very* | |
62 | ;;; Cscheme-specific; you must use cmuscheme.el. Interested parties are | |
63 | ;;; invited to port xscheme functionality on top of comint mode... | |

65 | ;; YOUR .EMACS FILE | |

68 | ;; | |

70 | ;; ; where to get it. This may or may not be necessary. | |
71 | ;; (setq load-path (cons (expand-file-name "~jones/lib/emacs") load-path)) | |
72 | ;; | |
73 | ;; ; Autoload run-scheme from file cmuscheme.el | |
74 | ;; (autoload 'run-scheme "cmuscheme" | |
75 | ;; "Run an inferior Scheme process." | |
76 | ;; t) | |
77 | ;; | |
78 | ;; ; Files ending in ".scm" are Scheme source, | |
79 | ;; ; so put their buffers in scheme-mode. | |
80 | ;; (setq auto-mode-alist | |
81 | ;; (cons '("\\.scm$" . scheme-mode) | |
82 | ;; auto-mode-alist)) | |
83 | ;; | |
84 | ;; ; Define C-c t to run my favorite command in inferior scheme mode: | |
85 | ;; (setq cmuscheme-load-hook | |
86 | ;; '((lambda () (define-key inferior-scheme-mode-map "\C-ct" | |
87 | ;; 'favorite-cmd)))) | |
88 | ;;; | |
89 | ;;; Unfortunately, scheme.el defines run-scheme to autoload from xscheme.el. | |
90 | ;;; This will womp your declaration to autoload run-scheme from cmuscheme.el | |
91 | ;;; if you haven't loaded cmuscheme in before scheme. Three fixes: | |
92 | ;;; - Put the autoload on your scheme mode hook and in your .emacs toplevel: | |
93 | ;;; (setq scheme-mode-hook | |
94 | ;;; '((lambda () (autoload 'run-scheme "cmuscheme" | |
95 | ;;; "Run an inferior Scheme" t)))) | |
96 | ;;; (autoload 'run-scheme "cmuscheme" "Run an inferior Scheme" t) | |
97 | ;;; Now when scheme.el autoloads, it will restore the run-scheme autoload. | |
98 | ;;; - Load cmuscheme.el in your .emacs: (load-library 'cmuscheme) | |
99 | ;;; - Change autoload declaration in scheme.el to point to cmuscheme.el: | |
100 | ;;; (autoload 'run-scheme "cmuscheme" "Run an inferior Scheme" t) | |
101 | ;;; *or* just delete the autoload declaration from scheme.el altogether, | |
102 | ;;; which will allow the autoload in your .emacs to have its say. | |

371 | MULTIPLE PROCESS SUPPORT | |
372 | =========================================================================== | |
373 | Cmuscheme.el supports, in a fairly simple fashion, running multiple Scheme | |
374 | processes. To run multiple Scheme processes, you start the first up with | |
375 | \\[run-scheme]. It will be in a buffer named *scheme*. Rename this buffer | |
376 | with \\[rename-buffer]. You may now start up a new process with another | |
377 | \\[run-scheme]. It will be in a new buffer, named *scheme*. You can | |
378 | switch between the different process buffers with \\[switch-to-buffer]. | |
379 | ||
380 | Commands that send text from source buffers to Scheme processes -- | |
381 | like scheme-send-definition or scheme-compile-region -- have to choose a | |
382 | process to send to, when you have more than one Scheme process around. This | |
383 | is determined by the global variable scheme-buffer. Suppose you | |
384 | have three inferior Schemes running: | |
385 | Buffer Process | |
386 | foo scheme | |
387 | bar scheme<2> | |
388 | *scheme* scheme<3> | |
389 | If you do a \\[scheme-send-definition-and-go] command on some Scheme source | |
390 | code, what process do you send it to? | |
391 | ||
392 | - If you're in a process buffer (foo, bar, or *scheme*), | |
393 | you send it to that process. | |
394 | - If you're in some other buffer (e.g., a source file), you | |
395 | send it to the process attached to buffer scheme-buffer. | |
396 | This process selection is performed by function scheme-proc. | |
397 | ||
398 | Whenever \\[run-scheme] fires up a new process, it resets scheme-buffer | |
399 | to be the new process's buffer. If you only run one process, this will | |
400 | do the right thing. If you run multiple processes, you can change | |
401 | scheme-buffer to another process buffer with \\[set-variable]. | |
402 | ||
403 | More sophisticated approaches are, of course, possible. If you find youself | |
404 | needing to switch back and forth between multiple processes frequently, | |
405 | you may wish to consider ilisp.el, a larger, more sophisticated package | |
406 | for running inferior Lisp and Scheme processes. The approach taken here is | |
407 | for a minimal, simple implementation. Feel free to extend it.") | |

430 | ;;; Created. | |
431 | ;;; | |
432 | ;;; 2/15/89 Olin | |
433 | ;;; Removed -emacs flag from process invocation. It's only useful for | |
434 | ;;; cscheme, and makes cscheme assume it's running under xscheme.el, | |
435 | ;;; which messes things up royally. A bug. | |
436 | ;;; | |
437 | ;;; 5/22/90 Olin | |
438 | ;;; - Upgraded to use comint-send-string and comint-send-region. | |
439 | ;;; - run-scheme now offers to let you edit the command line if | |
440 | ;;; you invoke it with a prefix-arg. M-x scheme is redundant, and | |
441 | ;;; has been removed. | |
442 | ;;; - Explicit references to process "scheme" have been replaced with | |
443 | ;;; (scheme-proc). This allows better handling of multiple process bufs. | |
444 | ;;; - Added scheme-send-last-sexp, bound to C-x C-e. A gnu convention. | |
445 | ;;; - Have not added process query facility a la cmulisp.el's lisp-show-arglist | |
446 | ;;; and friends, but interested hackers might find a useful application | |
447 | ;;; of this facility. | |
448 | ;;; | |
449 | ;;; 3/12/90 Olin | |
450 | ;;; - scheme-load-file and scheme-compile-file no longer switch-to-scheme. | |
451 | ;;; Tale suggested this. | |
