;; 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 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].")

Runs a Lisp interpreter as a subprocess of Emacs, with Lisp I/O through an

You can send text to the inferior Lisp process from other buffers containing

Lisp source.

switch-to-lisp switches the current buffer to the Lisp process buffer.

lisp-eval-defun sends the current defun to the Lisp process.

lisp-compile-defun compiles the current defun.
|
||
lisp-eval-region sends the current region to the Lisp process.
|
||
lisp-compile-region compiles the current region.

|
||
Prefixing the lisp-eval/compile-defun/region commands with

a \\[universal-argument] causes a switch to the Lisp process buffer after sending

the text.

Commands:

Return after the end of the process' output sends the text from the

Return before the end of the process' output copies the sexp ending at point
|

to the end of the process' output, and sends it.

Delete converts tabs to spaces as it moves back.
|

Tab indents for Lisp; with argument, shifts rest

of expression rigidly with the current line.

C-M-q does Tab on each line starting within following expression.

|
||
;;; 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.
