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

- MULTIPLE PROCESS SUPPORT
- ===========================================================================
- To run multiple Lisp processes, you start the first up
- with \\[inferior-lisp]. It will be in a buffer named `*inferior-lisp*'.
- Rename this buffer with \\[rename-buffer]. You may now start up a new
- process with another \\[inferior-lisp]. It will be in a new buffer,
- named `*inferior-lisp*'. You can switch between the different process
- buffers with \\[switch-to-buffer].
-
- Commands that send text from source buffers to Lisp processes --
- like `lisp-eval-defun' or `lisp-show-arglist' -- have to choose a process
- to send to, when you have more than one Lisp process around. This
- is determined by the global variable `inferior-lisp-buffer'. Suppose you
- have three inferior Lisps running:
- Buffer Process
- foo inferior-lisp
- bar inferior-lisp<2>
- *inferior-lisp* inferior-lisp<3>
- If you do a \\[lisp-eval-defun] command on some Lisp source code,
- what process do you send it to?
-
- - If you're in a process buffer (foo, bar, or *inferior-lisp*),
- you send it to that process.
- - If you're in some other buffer (e.g., a source file), you
- send it to the process attached to buffer `inferior-lisp-buffer'.
- This process selection is performed by function `inferior-lisp-proc'.
-
- Whenever \\[inferior-lisp] fires up a new process, it resets
- `inferior-lisp-buffer' to be the new process's buffer. If you only run
- one process, this does the right thing. If you run multiple
- processes, you can change `inferior-lisp-buffer' to another process
- buffer with \\[set-variable].")

- ;;; CHANGE LOG
- ;;; ===========================================================================
- ;;; 7/21/92 Jim Blandy
- ;;; - Changed all uses of the cmulisp name or prefix to inferior-lisp;
- ;;; this is now the official inferior lisp package. Use the global
- ;;; ChangeLog from now on.
- ;;; 5/24/90 Olin
- ;;; - Split cmulisp and cmushell modes into separate files.
- ;;; Not only is this a good idea, it's apparently the way it'll be rel 19.
- ;;; - Upgraded process sends to use comint-send-string instead of
- ;;; process-send-string.
- ;;; - Explicit references to process "cmulisp" have been replaced with
- ;;; (cmulisp-proc). This allows better handling of multiple process bufs.
- ;;; - Added process query and var/function/symbol documentation
- ;;; commands. Based on code written by Douglas Roberts.
- ;;; - Added lisp-eval-last-sexp, bound to C-x C-e.
- ;;;
- ;;; 9/20/90 Olin
- ;;; Added a save-restriction to lisp-fn-called-at-pt. This bug and fix
- ;;; reported by Lennart Staflin.
- ;;;
- ;;; 3/12/90 Olin
- ;;; - lisp-load-file and lisp-compile-file no longer switch-to-lisp.
- ;;; Tale suggested this.
- ;;; - Reversed this decision 7/15/91. You need the visual feedback.
- ;;;
- ;;; 7/25/91 Olin
- ;;; Changed all keybindings of the form C-c <letter>. These are
- ;;; supposed to be reserved for the user to bind. This affected
- ;;; mainly the compile/eval-defun/region[-and-go] commands.
- ;;; This was painful, but necessary to adhere to the gnumacs standard.
- ;;; For some backwards compatibility, see the
- ;;; cmulisp-install-letter-bindings
- ;;; function.
- ;;;
- ;;; 8/2/91 Olin
- ;;; - The lisp-compile/eval-defun/region commands now take a prefix arg,
- ;;; which means switch-to-lisp after sending the text to the Lisp process.
- ;;; This obsoletes all the -and-go commands. The -and-go commands are
- ;;; kept around for historical reasons, and because the user can bind
- ;;; them to key sequences shorter than C-u C-c C-<letter>.
- ;;; - If M-x cmulisp is invoked with a prefix arg, it allows you to
- ;;; edit the command line.
-
- (provide 'inf-lisp)
-
- ;;; inf-lisp.el ends here
