;; This file defines a shell-in-a-buffer package (shell mode) built on
;; top of comint mode. This is actually cmushell with things renamed
;; to replace its counterpart in Emacs 18. cmushell is more
1996-01-14 07:34:30 +00:00
;; featureful, robust, and uniform than the Emacs 18 version.

;; Since this mode is built on top of the general command-interpreter-in-
;; a-buffer mode (comint mode), it shares a common base functionality,
1996-01-14 07:34:30 +00:00
;; and a common set of bindings, with all modes derived from comint mode.
;; This makes these modes easier to use.
1990-11-05 10:06:02 +00:00
1996-01-14 07:34:30 +00:00
;; 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 shell mode, see the comments below.

;; When sending text from a source file to a subprocess, the process-mark can
1996-01-14 07:34:30 +00:00

"Major mode for interacting with an inferior shell.
\\[comint-send-input] after the end of the process' output sends the text from
the end of process to the end of the current line.
\\[comint-send-input] before end of process output copies the current line minus the prompt to
the end of the buffer and sends it (\\[comint-copy-old-input] just copies the current line).
\\[send-invisible] reads a line of text without echoing it, and sends it to
the shell. This is useful for entering passwords. Or, add the function
`comint-watch-for-password-prompt' to `comint-output-filter-functions'.
1990-11-05 10:06:02 +00:00
If you want to make multiple shell buffers, rename the `*shell*' buffer
using \\[rename-buffer] or \\[rename-uniquely] and start a new shell.
If you want to make shell buffers limited in length, add the function
`comint-truncate-buffer' to `comint-output-filter-functions'.
1990-11-05 10:06:02 +00:00
If you accidentally suspend your process, use \\[comint-continue-subjob]
to continue it.
`cd', `pushd' and `popd' commands given to the shell are watched by Emacs to
keep this buffer's default directory the same as the shell's working directory.
While directory tracking is enabled, the shell's working directory is displayed
by \\[list-buffers] or \\[mouse-buffer-menu] in the `File' field.
\\[dirs] queries the shell and resyncs Emacs' idea of what the current
1990-11-05 10:06:02 +00:00
directory stack is.
\\[dirtrack-mode] turns directory tracking on and off.

Customization: Entry to this mode runs the hooks on `comint-mode-hook' and
`shell-mode-hook' (in that order). Before each input, the hooks on
`comint-input-filter-functions' are run. After each shell output, the hooks
on `comint-output-filter-functions' are run.
1990-11-05 10:06:02 +00:00
Variables `shell-cd-regexp', `shell-chdrive-regexp', `shell-pushd-regexp'
and `shell-popd-regexp' are used to match their respective commands,
while `shell-pushd-tohome', `shell-pushd-dextract' and `shell-pushd-dunique'
control the behavior of the relevant command.

If BUFFER exists and shell process is running, just switch to BUFFER.
Program used comes from variable `explicit-shell-file-name',
1991-05-08 07:47:45 +00:00
or (if that is nil) from the ESHELL environment variable,
or else from SHELL if there is no ESHELL.
1992-09-04 07:35:10 +00:00
If a file `~/.emacs_SHELLNAME' exists, it is given as initial input
1991-05-08 07:47:45 +00:00
(Note that this may lose due to a timing error if the shell
discards input when it starts up.)
1992-09-04 07:35:10 +00:00
The buffer is put in Shell mode, giving commands for sending input
and controlling the subjobs of the shell. See `shell-mode'.
See also the variable `shell-prompt-pattern'.
1990-11-05 10:06:02 +00:00
1997-08-04 03:06:28 +00:00
To specify a coding system for converting non-ASCII characters
in the input and output to the shell, use \\[universal-coding-system-argument]
before \\[shell]. You can also specify this with \\[set-buffer-process-coding-system]
in the shell buffer, after you start the shell.
The default comes from `process-coding-system-alist' and
`default-process-coding-system'.
1991-05-08 07:47:45 +00:00
The shell file name (sans directories) is used to make a symbol name
1993-01-15 07:02:35 +00:00
such as `explicit-csh-args'. If that symbol is a variable,
1990-11-05 10:06:02 +00:00
its value is used as a list of arguments when invoking the shell.
Otherwise, one argument `-i' is passed to the shell.
\(Type \\[describe-mode] in the shell buffer for a list of commands.)"

;;; 2. It cannot infallibly deal with command sequences, though it does well
;;; with these and with ignoring commands forked in another shell with ()s.
;;; 3. More generally, any complex command is going to throw it. Otherwise,
;;; you'd have to build an entire shell interpreter in emacs lisp. Failing
;;; that, there's no way to catch shell commands where cd's are buried
;;; inside conditional expressions, aliases, and so forth.
1990-11-05 10:06:02 +00:00
;;;
;;; The whole approach is a crock. Shell aliases mess it up. File sourcing
;;; messes it up. You run other processes under the shell; these each have
;;; separate working directories, and some have commands for manipulating
;;; their w.d.'s (e.g., the lcd command in ftp). Some of these programs have
1991-05-08 07:47:45 +00:00

1990-11-05 10:06:02 +00:00
;;; do (e.g., the cd command in ftp). In shells that allow you job
;;; control, you can switch between jobs, all having different w.d.'s. So
;;; simply saying %3 can shift your w.d..
;;;
;;; The solution is to relax, not stress out about it, and settle for
;;; a hack that works pretty well in typical circumstances. Remember
;;; that a half-assed solution is more in keeping with the spirit of Unix,
1990-11-05 10:06:02 +00:00
;;; anyway. Blech.
;;;
;;; One good hack not implemented here for users of programmable shells
;;; is to program up the shell w.d. manipulation commands to output
;;; a coded command sequence to the tty. Something like
;;; ESC | <cwd> |
;;; where <cwd> is the new current working directory. Then trash the
;;; directory tracking machinery currently used in this package, and
;;; replace it with a process filter that watches for and strips out
;;; these messages.
(defun shell-directory-tracker (str)
"Tracks cd, pushd and popd commands issued to the shell.
This function is called on each input passed to the shell.
It watches for cd, pushd and popd commands and sets the buffer's
default directory to track these commands.
You may toggle this tracking on and off with M-x dirtrack-mode.
1990-11-05 10:06:02 +00:00
If emacs gets confused, you can resync with the shell with M-x dirs.

"Dynamically complete the environment variable at point.
Completes if after a variable, i.e., if it starts with a \"$\".
See `shell-dynamic-complete-as-environment-variable'.
This function is similar to `comint-dynamic-complete-filename', except that it
searches `process-environment' for completion candidates. Note that this may
not be the same as the interpreter's idea of variable names. The main problem
with this type of completion is that `process-environment' is the environment
which Emacs started with. Emacs does not track changes to the environment made
by the interpreter. Perhaps it would be more accurate if this function was
called `shell-dynamic-complete-process-environment-variable'.
Returns non-nil if successful."
