If not, see . ;;; Commentary: ;; Hacked from tea.el by Olin Shivers (shivers@cs.cmu.edu). 8/88 ;; This file defines 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 customizing 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?

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 might need to change `inferior-lisp-buffer' to whichever process buffer you want to use.")
