;; This is a grab bag of stuff for doing "gdb guile" in Emacs.
;; The var `gdb-guile-suggested-gdbinit' has a string that is
;; snarfed from ../HACKING.  (todo: Write `gdb-guile-init' to
;; send it to gdb...)

;;; Code:

(require 'cl)

(defun gdb-guile-display-scm ()
  (interactive)
  (save-excursion
    (let ((sym (thing-at-point 'symbol))
          (proc (get-buffer-process

                            (string-match "^.gud-." (buffer-name buf)))
                          (buffer-list)))))
      (mapc (lambda (template)
              (process-send-string proc (format template sym)))
