I realize that I should expect problems if I choose to live on the
bleeding edge, but I figure I might as well report this problem just
in case the developers aren't already aware of it.
The problem is with Emacs 21.3.50.1 that I checked out from CVS
sources and compiled using the emacs/mac/make-package shell script on
the Macintosh OS X (10.3.7). If I am editing in tex-mode and I run
the function 'tex-file' (by default bound to C-c C-f) emacs goes into
an infinite loop. The loop is in the function tex-mode.el:tex-start-shell
(defun tex-start-shell ()
(with-current-buffer
(make-comint
"tex-shell"
(or tex-shell-file-name (getenv "ESHELL") shell-file-name)
nil)
(let ((proc (get-process "tex-shell")))
(set-process-sentinel proc 'tex-shell-sentinel)
(set-process-query-on-exit-flag proc nil)
(tex-shell)
(while (zerop (buffer-size))
(sleep-for 1)))))
The function creates a shell using "make-comint", then waits for the
shell to start in the loop at the bottom. Presumably, when the shell
has started, it will issue a prompt and the (buffer-size) procedure
will return non-zero and break out of the loop. The problem is that
it never does.
I tried the following trivial program
(setq subshell (make-comint "subshell" "/bin/bash"))
(switch-to-buffer subshell)
And it does indeed create a subshell in a buffer, but the shell never
issues a prompt string. Setting the PS1 environment variable has no
effect in this buffer, for reasons I haven't figured out yet.
