|
32 ;;; This file defines a general command-interpreter-in-a-buffer package
|
|
|
33 ;;; (term mode). The idea is that you can build specific process-in-a-buffer
|
|
|
34 ;;; modes on top of term mode -- e.g., lisp, shell, scheme, T, soar, ....
|
|
|
35 ;;; This way, all these specific packages share a common base functionality,
|
|
|
36 ;;; and a common set of bindings, which makes them easier to use (and
|
|
|
37 ;;; saves code, implementation time, etc., etc.).
|
|
|
38
|
|
|
39 ;;; For hints on converting existing process modes (e.g., tex-mode,
|
|
|
40 ;;; background, dbx, gdb, kermit, prolog, telnet) to use term-mode
|
|
|
41 ;;; instead of shell-mode, see the notes at the end of this file.

381 set immediately.
|
|
|
382
|
|

383 This mode is typically customised to create inferior-lisp-mode,

384 shell-mode, etc.. This can be done by setting the hooks
|

385 term-input-filter-functions, term-input-filter, term-input-sender and

389 An input history is maintained of size `term-input-ring-size', and
|
|
|
390 can be accessed with the commands \\[term-next-input], \\[term-previous-input], and \\[term-dynamic-list-input-ring].
|
|
|
391 Input ring history expansion can be achieved with the commands
|
|
|
392 \\[term-replace-by-expanded-history] or \\[term-magic-space].
|
|
|
393 Input ring expansion is controlled by the variable `term-input-autoexpand',
|
|
|
394 and addition is controlled by the variable `term-input-ignoredups'.
|
|
|
395
|

396 Input to, and output from, the subprocess can cause the window to scroll to
|

397 the end of the buffer. See variables `term-scroll-to-bottom-on-input',
