35 ;;; This file defines a general command-interpreter-in-a-buffer package
|
|
|
36 ;;; (comint mode). The idea is that you can build specific process-in-a-buffer
|
|
|
37 ;;; modes on top of comint mode -- e.g., lisp, shell, scheme, T, soar, ....
|
|
|
38 ;;; This way, all these specific packages share a common base functionality,
|
|
|
39 ;;; and a common set of bindings, which makes them easier to use (and
|
|
|
40 ;;; saves code, implementation time, etc., etc.).
|
|
|
41
|
|
|
42 ;;; Several packages are already defined using comint mode:
|
|
|
43 ;;; - shell.el defines a shell-in-a-buffer mode.
|
|
|
44 ;;; - cmulisp.el defines a simple lisp-in-a-buffer mode.
|
|
|
45 ;;;
|
|
|
46 ;;; - The file cmuscheme.el defines a scheme-in-a-buffer mode.
|
|
|
47 ;;; - The file tea.el tunes scheme and inferior-scheme modes for T.
|
|
|
48 ;;; - The file soar.el tunes lisp and inferior-lisp modes for Soar.
|
|
|
49 ;;; - cmutex.el defines tex and latex modes that invoke tex, latex, bibtex,
|
|
|
50 ;;; previewers, and printers from within emacs.
|
|
|
51 ;;; - background.el allows csh-like job control inside emacs.
|
|
|
52 ;;; It is pretty easy to make new derived modes for other processes.
|
|
|
53
|
|
|
54 ;;; For documentation on the functionality provided by comint mode, and
|
|
|
55 ;;; the hooks available for customising it, see the comments below.
|
|
|
56 ;;; For further information on the standard derived modes (shell,
|
|
|
57 ;;; inferior-lisp, inferior-scheme, ...), see the relevant source files.
|
|
|
58
|
|
|
59 ;;; For hints on converting existing process modes (e.g., tex-mode,
|
|
|
60 ;;; background, dbx, gdb, kermit, prolog, telnet) to use comint-mode
|
|
|
61 ;;; instead of shell-mode, see the notes at the end of this file.

366 This mode is customised to create major modes such as Inferior Lisp

|
|
368 `comint-input-filter-functions', `comint-input-filter', `comint-input-sender'
|
|
|
369 and `comint-get-old-input' to appropriate functions, and the variable

370 `comint-prompt-regexp' to the appropriate regular expression.

372 An input history is maintained of size `comint-input-ring-size', and

|
|
373 can be accessed with the commands \\[comint-next-input], \\[comint-previous-input], and \\[comint-dynamic-list-input-ring].
|
|
|
374 Input ring history expansion can be achieved with the commands
|
|
|
375 \\[comint-replace-by-expanded-history] or \\[comint-magic-space].
|
|
|
376 Input ring expansion is controlled by the variable `comint-input-autoexpand',
|
|
|
377 and addition is controlled by the variable `comint-input-ignoredups'.
|
|
|
378
|

379 Commands with no default key bindings include `send-invisible',
|

|
|
|
381 `comint-magic-space'.
|
|
|
382
|
|
|
383 Input to, and output from, the subprocess can cause the window to scroll to
|
|
|
384 the end of the buffer. See variables `comint-output-filter-functions',
|
|
|
385 `comint-scroll-to-bottom-on-input', and `comint-scroll-to-bottom-on-output'.

1242 point as input to the process. Before the process output mark, calls value
|
|
|
1243 of variable `comint-get-old-input' to retrieve old input, copies it to the
|
|
|
1244 process mark, and sends it. If variable `comint-process-echoes' is nil,
|
|

1245 a terminal newline is also inserted into the buffer and sent to the process
|
|
|
1246 \(if it is non-nil, all text from the process mark to point is deleted,

1247 since it is assumed the remote process will re-echo it).

1251 of `comint-input-filter-functions' is called on the input before sending it.
|
|
|
1252 The input is entered into the input history ring, if the value of variable
|
|

1253 `comint-input-filter' returns non-nil when called on the input.
|
|
|
1254

1255 If variable `comint-eol-on-send' is non-nil, then point is moved to the

1256 end of line before sending the input.

1257
|
|
|
1258 If variable `comint-append-old-input' is non-nil, then the results of
|
|
|
1259 calling `comint-get-old-input' are appended to the end of the buffer.
|

1260 The new input will combine with any partially-typed text already present

1262 appended input, and a message is displayed prompting the user to type
|

1263 \\[comint-send-input] again.

|
|
|
1265 The values of `comint-get-old-input', `comint-input-filter-functions' and

1266 `comint-input-filter' are chosen according to the command interpreter running
|
|
|
1267 in the buffer. E.g.,
|
|
|
1268
|
|
|
1269 If the interpreter is the csh,
|
|
|
1270 comint-get-old-input is the default: take the current line, discard any
|
|
|
1271 initial string matching regexp comint-prompt-regexp.
|
|
|
1272 comint-input-filter-functions monitors input for \"cd\", \"pushd\", and
|
|
|
1273 \"popd\" commands. When it sees one, it cd's the buffer.
|
|
|
1274 comint-input-filter is the default: returns t if the input isn't all white
|
|
|
1275 space.
|
|
|
1276
|
|
|
1277 If the comint is Lucid Common Lisp,
|
|
|
1278 comint-get-old-input snarfs the sexp ending at point.
|
|
|
1279 comint-input-filter-functions does nothing.
|
|
|
1280 comint-input-filter returns nil if the input matches input-filter-regexp,
|
|
|
1281 which matches (1) all whitespace (2) :a, :c, etc.
