Re: command-history-repeat used with query-search

[Alan <wehmann@fnal.gov>]

Although I intentionally did not include the code earlier, I'll do so now (it's been improved a bit since I started this topic).  In a similar vein, I've modified the operation of "occur" so that it can use "word-at-point" to define the default--following the example of what happens with "occur" in XEmacs (but I'm not including that code here).

(defun command-history-repeat ()
  "Repeat the command shown on the current line.
The buffer for that command is the previous current buffer.
If a query command, operate in the previous current buffer"
  (interactive)
  (let ((aw-cmd-buf (current-buffer))
        (aw-buf-list (buffer-list))
        aw-edit-buf aw-query aw-cmd-str aw-m1
        aw-edebug-data aw-edebug-def-mark aw-edebug-buffer)
    ;; running edebug results in the code buffer being present in (buffer-list), so delete that buffer from the
    ;; list that we actually use
    (when (featurep 'edebug)
      (setq aw-edebug-data (get edebug-function 'edebug)
            aw-edebug-def-mark (car aw-edebug-data)
            aw-edebug-buffer (marker-buffer aw-edebug-def-mark)))
    ;;(delq (get-buffer "chist-fix.el") aw-buf-list)
    (delq aw-edebug-buffer aw-buf-list)
    (setq aw-edit-buf (car (cdr aw-buf-list)))
    (save-excursion
      (beginning-of-line)
      (setq aw-m1 (point))
      (forward-sexp)
      (setq aw-cmd-str (buffer-substring aw-m1 (point)))
      (setq aw-query (string-match "query" aw-cmd-str)))
    (cond
     ((not aw-query)
      (save-excursion
        (eval (prog1 (read aw-cmd-str)
                (set-buffer aw-edit-buf)))))
     ;;
     (aw-query
      (pop-to-buffer aw-edit-buf)
      (eval (prog1 (read aw-cmd-str)
              (set-buffer aw-edit-buf)))
      (pop-to-buffer aw-cmd-buf)))))
