;;; Commentary:
|
|
|
|
;; The file msdos.el in the next mail message opens an *msdos* buffer
|
|
;; in shell-mode and msdos-minor-mode. When cmdproxy.exe/command.com
|
|
;; is the emacs shell, then this gets various setting right that M-x
|
|
;; shell currently misses. The function M-x msdos-minor-mode could be
|
|
;; automatically run by emacs in shell-mode in that case.
|
|
|
|
;; When bash is the emacs shell, msdos.el still opens a
|
|
;; cmdproxy.exe/command.com shell in the buffer *msdos*. There are
|
|
;; occasions when it is necessary to run DOS character-based programs
|
|
;; in an emacs window.
|
|
|
|
;; I followed the suggestion by AndrewI to look at M-x shell and modify
|
|
;; it. It turns out not to have been trivial.
|
|
|
|
;; I've listed it as part of ESS (emacs speaks statistics) for now. I
|
|
;; will be happy to sign it over to FSF and have it become part of the
|
|
;; standard distribution for windows machines.

"Run an inferior msdos shell, with I/O through buffer *msdos*.
|
|
This function is intended to be used in an Ntemacs session in which
|
|
bash is the primary shell. But sometimes an MSDOS window, within emacs,
|
|
is also needed.
|
|
|
|
If buffer exists but shell process is not running, make new shell.
|
|
If buffer exists and shell process is running, just switch to buffer `*msdos*'.
|
|
Program used comes from variable `explicit-msdos-shell-file-name'.
|
|
If a file `~/.emacs_SHELLNAME' exists, it is given as initial input
|
|
(Note that this may lose due to a timing error if the shell
|
|
discards input when it starts up.)
|
|
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'.
|
|
|
|
The buffer is put into \\[msdos-minor-mode]. See `msdos-minor-mode'.
|
|
|
|
The COMSPEC environment variable in the inferior shell, but not in the emacs
|
|
process, is set to `explicit-msdos-comspec-file-name'.
|
|
The SHELL environment variable in the inferior shell, but not in the emacs
|
|
process, is set to `explicit-msdos-shell-file-name'.
|
|
|
|
The shell file name (sans directories) is used to make a symbol name
|
|
such as `explicit-csh-args'. If that symbol is a variable,
|
|
its value is used as a list of arguments when invoking the shell.
|

|
|
\(Type \\[describe-mode] in the shell buffer for a list of commands.)"
