A thought came to me that directory tracking in shell-mode can be done
in very simple and robust way. One just needs to call emacsclient from
prompt string in order to set value of default-directory of the shell
buffer. Name of the shell buffer can be transferred to the shell process
using environment. So I have the following solution.
In init.el:
(advice-add 'comint-exec :around
#'(lambda (f buffer &rest args)
(let ((process-environment (cons (concat "EMACS_BUFFER="
(buffer-name buffer))
process-environment)))
(apply f buffer args)))
'((name . "envbuf")))
At the end of ~/.bashrc:
if [ -n "$EMACS_BUFFER" ]; then
set_emacs_dir() {
>/dev/null 2>&1 emacsclient --eval \
'(with-current-buffer "'"$EMACS_BUFFER"'" (setq default-directory
"'"$PWD"'"))'
}
PS1='`set_emacs_dir`'"$PS1"
fi
