80281b01 RS |
621 | |
622 | This construct makes buffer BUFNAME empty before running BODY. | |
623 | It does not make the buffer current for BODY. | |
624 | Instead it binds `standard-output' to that buffer, so that output | |
625 | generated with `prin1' and similar functions in BODY goes into | |
626 | the buffer. | |
627 | ||
628 | At the end of BODY, this marks buffer BUFNAME unmodifed and displays | |
629 | it in a window, but does not select it. The normal way to do this is | |
630 | by calling `display-buffer', then running `temp-buffer-show-hook'. | |
631 | However, if `temp-buffer-show-function' is non-nil, it calls that | |
632 | function instead (and does not run `temp-buffer-show-hook'). The | |
633 | function gets one argument, the buffer to display. | |
634 | ||
635 | The return value of `with-output-to-temp-buffer' is the value of the | |
636 | last form in BODY. If BODY does not finish normally, the buffer | |
637 | BUFNAME is not displayed. | |
638 | ||
639 | This runs the hook `temp-buffer-setup-hook' before BODY, | |
640 | with the buffer BUFNAME temporarily current. It runs the hook | |
641 | `temp-buffer-show-hook' after displaying buffer BUFNAME, with that | |
642 | buffer temporarily current, and the window that was used to display it | |
643 | temporarily selected. But it doesn't run `temp-buffer-show-hook' | |
644 | if it uses `temp-buffer-show-function'. | |
