drkm was using code from my emacs-wiki program as an example for this.
You're right in that using a non-nil VISIT argument was a bad idea.
I've also worked around the "prompted to save a temp buffer" problem
by making a macro called `emacs-wiki-with-temp-buffer' as follows.
The condition-case call is mainly used for displaying diagnostic
information, so it might not be generally useful. A part of the
cleanup code,
(when (buffer-live-p ,temp-buffer)
(with-current-buffer ,temp-buffer
(set-buffer-modified-p nil))
(... (kill-buffer ,temp-buffer)))
might perhaps be generally useful, but this is mostly an FYI rather
than a feature request.
(defmacro emacs-wiki-with-temp-buffer (&rest body)
"Create a temporary buffer, and evaluate BODY there like `progn'.
See also `with-temp-file' and `with-output-to-string'.
Unlike `with-temp-buffer', this will never attempt to save the temp buffer."
(let ((temp-buffer (make-symbol "temp-buffer")))
`(let ((,temp-buffer (generate-new-buffer " *emacs-wiki-temp*")))
(unwind-protect
(condition-case err
(with-current-buffer ,temp-buffer
,@body)
(error
(if (fboundp 'display-warning)
(display-warning 'emacs-wiki
(format "%s: Error occurred: %s"
(emacs-wiki-page-name)
err)
:warning)
(message "%s: Error occurred: %s"
(emacs-wiki-page-name)
err))))
(when (buffer-live-p ,temp-buffer)
(with-current-buffer ,temp-buffer
(set-buffer-modified-p nil))
(unless debug-on-error (kill-buffer ,temp-buffer)))))))
(put 'emacs-wiki-with-temp-buffer 'lisp-indent-function 0)
(put 'emacs-wiki-with-temp-buffer 'edebug-form-spec '(body))
