From: "Craig Amey" <camey(a)reshape.com&gt; Date: Wed, 12 Dec 2001 10:35:32 -0800 This doesn't seem to work in Xemacs, except for the trivial case of typing cd pathname at the prompt. shellt.el, the fix for GNU Emacs doesn't seem to work (this works by appending an ; echo 'pwd' to the input stream). Just about anything I've tried confuses or fails to resync the tracking ... such as cd $ENV_DIR This works if xemacs knows the value of $ENV_DIR (cd $HOME works) cd dir # where dir is in cdpath cd 'pwd' You can advise shell-process-cd, for example, here, I advise the function to strip off string quotes (this is needed for cd "/Program Files/foobar") (defadvice shell-process-cd (before strip-quotes first activate) "jwm: Strip quotes from filename" (if (and (> (length arg) 2) (eql (aref arg 0) ?\") (eql (aref arg (1- (length arg))) ?\")) (setq arg (subseq arg 1 (- (length arg) 1))))) You could advise shel-process-cd and shell-process-pushd to handle cdpath and ` quotes. -jeff

Specifically, there are escapes that let me put the "\w" directory code into the window title bar. Could not the terminal emulator be programmed to respond to the escape sequences by setting some variable and/or running a hook? -- David A. Cobb, Software Engineer, Public Access Advocate. Just to make sure that I understand, are you suggesting doing something like this: In bash, do export PS1="[cd=\\w]\\s%" Which causes the prompt to be something like: [cd=/home/jeff/.xemacs]bash% And then making comint strip off the [cd=...] stuff to track the current directory, which, I think could be done by using a comint-output-filter-function. Ok, this might not be the most wacky idea I've heard all day... -jeff

But your basic point that you can't really keep up with the directory tracking is taken. So just for amusement, I implemented what is a proof of concept hack. I went to the bash shell, and did the following bash% export PS1='\e]0;\w\a\s% ' This is pretty much equivalent to export PS1=$(echo -e '\033]0;\\w\007[\\u＠\\h \\W]\\$ ') Except that I prefer a shorter prompt. Funny how I have completely forgotten anything about term escape sequences. I reclaimed that memory years ago. Then I defined the following elisp hack that is copied from comint-strip-ctrl-m. (defun comint-strip-cd-hack (&optional string) (interactive) (let ((pmark (process-mark (get-buffer-process (current-buffer))))) (save-excursion (goto-char (if (interactive-p) comint-last-input-end comint-last-output-start)) (while (re-search-forward "^[\e][\]][0][;][^\a]+[\a]" pmark t) (let ((match (match-string 0))) (message "cd is %s" (subseq match 4 (1- (length match))))) (replace-match "" t t))))) (add-hook 'comint-output-filter-functions 'comint-strip-cd-hack) The shell echoes something like \033]0;~/.xemacs\007bash% The comint-strip-cd-hack is run and matches the \033]0;~/.xemacs\007 and removes that out of the buffer, and prints out the message that cd is ~/.xemacs, and leaves only 'bash% ' in the buffer. So, this could be a useful hack, at least for comint shells that support this type of prompt. -jeff
